ABSTRACT

Congenital entropion, an abnormal condition in which the eyelids roll inward, with the eyelashes losing their normal angulation and tilting toward the eye, especially in the lower eyelids and inner canthus, often occurs in infants and young children. Congenital entropion may lead to corneal epithelial abrasion, inflammation and ulcer, which may affect the function of the eye if not treated in time. Early surgical intervention is helpful to the health of children's eyes. The purpose of surgery is to change the structure of eyelid and weaken the force of entropion, thus improving the symptoms and corneal astigmatism. At present, there are many surgical treatments for congenital entropion. In this paper, the advantages, disadvantages and indications of these treatments are analyzed and summarized, providing a reference for clinical practice.

ABSTRACT

Tongxie Yaofang, also known as Baizhu Shaoyaosan, was first recorded in Danxi's Experiential Therapy (《丹溪心法》) by ZHU Danxi in the Yuan dynasty. It is composed of Atractylodis Macrocephalae Rhizoma, Paeoniae Radix Alba, Citri Reticulatae Pericarpium, and Saposhnikoviae Radix, and serves as the representative prescription for the treatment of painful diarrhea. It has the functions of tonifying the spleen, emolliating the liver, relieving pain, and checking diarrhea, and is mainly used in the treatment of gastrointestinal diseases such as irritable bowel syndrome (IBS) and ulcerative colitis (UC). In addition, it is effective in treating gastrointestinal disorders with mental and psychological abnormalities, as well as obstinate anorexia in children, depression syndrome, and respiratory diseases. Experimental research and clinical practice have shown that Tongxie Yaofang has multi-component, multi-pathway, and multi-target characteristics in the treatment of diseases. The mechanism of Tongxie Yaofang in treating diseases is mainly attributed to anti-inflammation, immune function regulation, intestinal hypersensitivity improvement, emotion regulation, etc. Monoterpene glycosides, flavonoids, chromones, lactones, and other components contained play an important therapeutic role. The research on the systems biology of Tongxie Yaofang, such as metabolomics, proteomics, and network pharmacology, provides a scientific basis for clarifying its mechanism of action and expanding its clinical application. However, there are still some problems to be solved, such as difficulty in combining diseases and syndromes and lack of in-depth systematic research. Through the retrieval and collation of relevant literature, this paper systematically reviewed the material basis, pharmacological effects, and systems biology research of Tongxie Yaofang, aiming to lay a foundation for in-depth research on its mechanism in treating diseases and rational application in clinical practice.

ABSTRACT

ObjectiveTo compare the effects of different processing methods in ancient and modern times on the chemical components of Lilii Bulbus decoction, and to provide experimental support for the origin processing, decoction piece processing and clinical application of this herb. MethodUltra high performance liquid chromatography tandem quadrupole electrostatic field orbitrap high resolution mass spectrometry(UHPLC-Q-Orbitrap HRMS) was used for structural identification of the compounds using excimer ions, secondary MS and characteristic fragment ions, and referring to relevant literature and database information. Principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were used to screen the main differential components, the differential components were quantitatively studied by high performance liquid chromatography(HPLC), in order to compare the types and contents of chemical components in the decoction of different processing products of Lilii Bulbus. ResultA total of 24 chemical components were identified from the decoction of different processed products of Lilii Bulbus, water extract and scalding liquid of fresh Lilii Bulbus, including 17 phenols, 5 saponins and 2 alkaloids. Compared with the fresh Lilii Bulbus decoction, the contents of regaloside A, p-coumaric acid, colchicine and other components in the decoction of dry Lilii Bulbus processed by scalding method decreased, the content of regaloside C in the decoction of dry Lilii Bulbus processed by steaming method decreased, and the contents of regaloside A and regaloside C in the decoction of fresh Lilii Bulbus processed by water immersion also decreased. Compared with the decoction of dry Lilii Bulbus processed by scalding method, the overall content of components in the fresh Lilii Bulbus decoction and the decoction of fresh Lilii Bulbus processed by water immersion was higher, the contents of components in the decoction of dry Lilii Bulbus processed by steaming method was higher, except for the slightly lower content of regaloside C. ConclusionDifferent processing processes have a certain effect on the types and contents of chemical components in Lilii Bulbus decoction. Scalding process is beneficial to the preservation of Lilii Bulbus, but can cause the loss of effective components. Compared with scalding method, steaming method can prevent browning of Lilii Bulbus and reduce the loss of its active ingredients. The processing method of removing foam after overnight immersion proposed by ZHANG Zhongjing may be more conducive to the treatment of Baihe disease, which can provide reference for the clinical rational application and mechanism research of different processed products of Lilii Bulbus.

ABSTRACT

OBJECTIVE To optimize the pressurized processing technology of Strychnos nux-vomica boiled with mung beans. METHODS The least squares method was used to establish a one-dimensional model for the effects of four factors, namely, processing time, processing pressure, mung bean dosage and water added, on the contents of strychnine and toxiferine, and the multivariate model hypothesis was proposed by analyzing the function of one-dimensional model. Based on the orthogonal experiment, the genetic algorithm was used to solve the undetermined coefficients in the model. A bi-objective optimization model based on strychnine and toxiferine content was constructed according to the actual conditions, and the optimal technology was obtained by solving the model function and validated. RESULTS The optimal processing technology was boiling S. nux-vomica with mung beans at 2.393 MPa saturated steam pressure for 5.5 h, and then draining; rinsing to remove mung beans, scraping off the bark of S. nux-vomica and cutting into slice of 0.6 mm; using 180 g of mung beans and 15 L of water per 500 g of S. nux- vomica. CONCLUSIONS The optimized pressurized processing technology is stable and feasible, and can provide a reference for the optimization of processing technology of S. nux-vomica boiled with mung beans.

ABSTRACT

As an important element of medical and health sector innovation, the translation of scientific and technological achievements plays a key role in promoting their clinical application and meeting the medical needs of the people. The authors sorted out the problems in such translation at these affiliated hospitals in terms of " people", " finance", " material", and " system". Starting from 2017, the Tenth People′s Hospital Affiliated to Tongji University has explored such practices as establishing hospital-led clinical medical science and technology innovation parks and technology service limited companies. These practices aimed to address the issues of insufficient hospital scientific and technological innovation capabilities and the gap between the hospital′s operation mechanism to translate its scientific and technological achievements and the enterprises and the market. The clinical medical science and technology innovation park integrating administration, industry, education, research, medicine and application, has taken multiple measures to attract excellent research talents and projects from within and beyond the hospital, promote the implementation of innovative scientific research projects. The hospital also established a health industry mode with engagement of social capital from large enterprises. The Technology Services Co., Ltd. was based on the incubation and translation of hospital achievements, combining market and clinical needs, promoting multi-party cooperation between hospitals and external enterprises, improving the chain operation mechanism of hospital scientific and technological achievements translation work, and alleviating the problem of insufficient research pilot funds and productibility funds by means of hospital-led fundraising. The number of patent authorizations of hospitals had increased from 23 cases in 2018 to 105 in 2022, and the amount of patent conversion had increased from 2 million yuan in 2020 to 11 million yuan in 2022. It is recommended that affiliated hospitals of universities further improve the organizational structure of achievement translation, strengthen their professional talent teams, improve their operation mechanism of achievement translation, build a platform for medical school-enterprise cooperation, and improve the evaluation mechanism of translation assessment, in order to promote a virtuous cycle of hospital′s scientific and technological achievement translation work.

ABSTRACT

Objective:To explore the role of navigation-assisted valgus stress method in avoiding excessive correction of lower limb mechanical axis after high tibial osteotomy (HTO).Methods:A retrospective study was carried out on osteoarthritis (OA) patients who were treated with HTO for medial compartment pain of knee from January 2020 to March 2022 in the Department of Joint Surgery, Shanghai Changhai Hospital, the First Affiliated Hospital of Naval Medical University. According to the different ways of confirming alignment during operation, they were divided into computer navigation assisted valgus stress HTO group (referred to as navigation group) and traditional rod fluoroscopy HTO group (referred to as traditional group). There were 28 patients in the navigation group, 10 males and 18 females, with age of 54.4±9.1 years (range, 41-73 years) and body mass index of 26.1±3.3 kg/m 2 (range, 19.8-35.2 kg/m 2); There were 30 patients in the traditional group, 13 males and 17 females, aged 56.9±8.5 years (range, 40-70 years), with a body mass index of 25.7±4.0 kg/m 2 (range, 19.2-32.9 kg/m 2). Measuring the mechanical femoral tibial angle (mFTA), joint line convergence angle (JLCA), medial proximal tibial angle (MPTA), Lysholm score and Hospital for Special Surgery (HSS) score before operation and at the last follow-up of the two groups, and conduct statistical analysis. Results:Both groups were followed up. The follow-up time of navigation group and traditional group was 21.3±8.7 months and 22.5±7.6 months, respectively, with no significant difference ( t=0.53, P=0.596). There were significant differences between the two groups in the amount of mechanical axis correction (ΔmFTA) and the amount of bone correction (ΔMPTA) ( t=2.09, P=0.041; t=2.58, P=0.012), while there was no significant difference in ΔJLCA ( t=0.32, P=0.753). In the navigation group, there were 9 cases (32%) of undercorrection, 17 cases (61%) with acceptable alignment, and 2 cases (7%) with over correction, while in the traditional group, there were 5 cases (17%) with under correction, 13 cases (43%) with acceptable alignment, and 12 cases (40%) with over correction. There was significant difference in the distribution rate of alignment between the two groups ( P=0.012), and the rate of overcorrection in the navigation group was significantly lower than that in the control group (7% vs. 40%, P=0.005). The intra group correlation coefficient between the navigation correction mechanical axis and ΔmFTA was 0.787. There was no significant difference in Lysholm score and HSS score between the two groups before and after surgery (all P>0.05), and they were significantly improved after operation (all P<0.05). Conclusion:Navigation-assisted valgus stress method HTO is reliable, which can accurately achieve the target alignment, reduce the incidence of over correction, and obtain good clinical results.

ABSTRACT

【Objective】 To investigate the improvement of signal uniformity in cardiac magnetic resonance image by adjusting the transmit gain (TG). 【Methods】 For this study we recruited 11 volunteers for cardiac MR scans between July and September 2018. The scanner of US GE Discovery 750 3.0T superconducting MRI was used. We divided the volunteers into normal group and overweight group according to their individual BMI index. The imaging sequences consisted of the black blood double inversion recovery sequence (T1 weighted image and T2 weighted image) and breath-holding black blood three-inversion recovery sequence (FST1 weighted image and FST2 weighted image). All sequences were performed across different TG values, including 150, 160, 170, 180, and 190. The images’ quality was scored by two experienced radiologists using a four-point system based on the blinding principle. The paired variance analysis was made to compare the image quality of different TG groups. 【Results】 We observed consistent results in both normal and overweight groups. The optimal TG value was 160 for black blood triple inversion recovery sequence and 170 for black blood double inversion recovery sequence. 【Conclusion】 Adjusting the TG value can improve the signal uniformity of the myocardium, thereby improving the quality of images.

ABSTRACT

Objective:To evaluate the role of epidermal growth factor (EGF) in repair of lung tissues in mice with acute respiratory distress syndrome (ARDS).Methods:Fifty SPF male C57BL/6 mice, aged 6-8 weeks, weighing 21-23 g, were divided into 5 groups ( n=10 each) using a random number table method: control group (group C), EGF group, LPS+ PBS group, LPS+ EGF group and AG1478+ LPS+ EGF group.PBS 0.1 ml was intraperitoneally injected in group C. EGF 10 μg (0.1 ml) was intraperitoneally injected in group EGF.The equal volume of PBS and EGF 10 μg was intraperitoneally injected at 12 h after tracheal infusion of LPS in group LPS+ PBS and group LPS+ EGF, respectively.EGF receptor (EGFR) antagonist AG1478 1 mg was intraperitoneally injected, 30 min later LPS was tracheally instilled, and 12 h later EGF 10 μg was intraperitoneally injected in group AG1478+ LPS+ EGF.ARDS model was developed by endotracheal instillation of LPS 3 mg/kg.The mice were sacrificed on the 1st and 5th days after development of the model, and lung tissues were obtained for microscopic examination of the pathological changes which were scored after HE staining.Bronchoalveolar lavage was performed on 5th day after development of the model and before sacrifice, and bronchoalveolar lavage fluid (BALF) was collected to detect total protein concentration (by BCA method) and IL-6 and TNF-α concentrations (by enzyme-linked immunosorbent assay). Lung tissues were obtained for determination of the wet/dry lung weight ratio (W/D ratio), expression of lung surfactant associated protein C (SP-C) and proliferating nuclear antigen (PCNA) (by immunofluorescence method), and expression of EGFR, phosphorylated EGFR (p-EGFR), protein kinase B (Akt), and phosphorylated Akt (p-Akt) (by Western blot). Results:Compared with group C, the pathological score, W/D ratio, concentrations of total protein, IL-6 and TNF-α in BALF and neutrophil count were significantly increased, the number of cells co-expressing SP-C and PCNA was increased, and p-EGFR/EGFR and p-Akt/Akt ratios were increased in group LPS+ PBS ( P<0.01), and no significant change was found in the indexes mentioned above in group EGF ( P>0.05). Compared with group LPS+ PBS, the pathological score, W/D ratio, concentrations of total protein, IL-6 and TNF-α in BALF and neutrophil count were significantly decreased, the number of cells co-expressing SP-C and PCNA was increased, and p-EGFR/EGFR and p-Akt/Akt ratios were increased in group LPS+ EGF ( P<0.01). Compared with group LPS+ EGF, the pathological score, W/D ratio, concentrations of total protein, IL-6 and TNF-α in BALF and neutrophil count were significantly increased, the number of cells co-expressing SP-C and PCNA was decreased, and p-EGFR/EGFR and p-Akt/Akt ratios were decreased in group AG1478+ LPS+ EGF ( P<0.01). Conclusions:EGF can promote the repair of lung tissues in mice with ARDS, and the mechanism may be related to activation of EGFR signaling pathway and promotion of proliferation of alveolar epithelial cell type Ⅱ.

ABSTRACT

Objective:To perform cross-cultural adaption of the KING′s Parkinson′s Disease Pain Scale (KPPS), explore its reliability and validity in Chinese Parkinson′s disease (PD) patients, and to create the new version of the pain scale which adapts to the Chinese PD patients.Methods:This study enrolled 225 patients, including 121 men and 104 women who were selected from the Outpatient Center of Movement Disorders Clinic of the Second Affiliated Hospital of Soochow University from July 2018 to July 2020. All patients completed the evaluation of the Chinese Version of KPPS (KPPS-CV). According to the preliminary evaluation results, the expert group modified KPPS-CV after discussion, and developed a Modified KPPS-CV (MKPPS-CV). These patients then completed the MKPPS-CV evaluation during the 3-month follow-up. Cross-cultural adaptation was performed according to published international guidelines that include translation, back-translation, expert review, and pretesting. The following psychometric properties were evaluated: basic item analysis; floor and ceiling effects; construct validity; content validity; criterion validity (Spearman′s rho between the KPPS-CV and Numeric Rating Scale); internal consistency reliability (Cronbach′s alpha); test-retest reliability (intra-class correlation coefficient, ICC).Results:In item analysis, 50% of the items had poor discrimination (critical ratio<3.0), and floor effect was found in all domains (proportion of 0 point>15%). The items were reclassified after exploratory factor analysis. The content validity of item 3, item 10 and item 11 was low (item-level content validity index<0.78). Criterion validity showed the highest correlations (Spearman′s rho>0.88) between the KPPS-CV and Numeric Rating Scale. While overall scale reliability was minimally acceptable at 0.46, which showed a poor reliability of this scale. Test-retest reliability was excellent for each item (Spearman's rho>0.85). The Cronbach′s alpha of MKPPS-CV (0.76) was higher than that of KPPS-CV (0.46). It showed a great improvement after the modifying.Conclusions:When using scales that are not developed for local populations, differences in culture and clinical practices should be taken into account. MKPPS-CV is an acceptable, valid measure to evaluate pain in Chinese PD patients, which is more suitable for Chinese people.

ABSTRACT

Objective:To investigate the effects of sacral neuromodulation (SNM)using the new six-contact electrode vs. the four-contact electrode in patients with refractory overactive bladder.Methods:The clinical data of 29 patients underwent SNM testing therapy from January 2018 to January 2020 in China Rehabilitation Research Center were reviewed. In six-contact points electrode group 16 patients accepted SNM with new six-contact points electrode, while 13 patients in four-contact points electrode group accepted SNM with four-contact points electrode. There were no significant differences between the two group in age [(51.63±4.67) vs. (51.85±7.18) years], gender (male/female, 4/12 and 5/8), urination frequency [(22.10±9.05) vs. (21.79±8.05) times/24h], mean voided volume [(135.68±56.98) vs. (131.00±53.05) ml], and urgency score [(2.78±0.97) vs. (3.02±0.91)] (all P>0.05). The number of sensitive contact points, the ratio of reaction contact points, operation time of stage I and the success rate of two groups were calculated. Results:The mean number of sensitive points of six-contact points electrode group (3.31± 0.95) was significantly higher than that of the four-contact points electrode group (1.85± 0.38), ( P<0.05). There was no significant difference in the ratio of reaction contact points [ (96.87±6.71)% vs. (96.15± 9.39)%] and operation time of stage I [(71.25± 18.21)min vs.(68.85± 10.83)min]between six-contact points electrode group and four-contact points electrode group ( P<0.05). The contact E4 and E5 of six-contact electrodes had similar reaction voltage ( P>0.05). The implant rate of six-contact points electrode group was (14/16, 87.5%), which was higher than that of four-contact points electrode group (10/13, 76.9%), but there was no statistical difference ( P>0.05). Conclusions:This study showed that six-contact electrodes has more sensitive points compared with four-contact electrodes. Application of six contact electrodes, patients might get a higher implant rate.

ABSTRACT

Objective:To investigate the long term outcome of artificial urinary sphincter implantation for patients with stress urinary incontinence.Methods:The data of 46 patients who underwent artificial urethral sphincter implantation in China Rehabilitation Research Center from April 2002 to April 2022 were retrospectively analyzed.The patients’ age ranged from 19-80 years old (median 45.6 years). There were 45 males and 1 female. The history of illness was 8 months to 33 years. The patients category were urethral injuries associated urinary incontinence ( n=24), neurogenic urinary incontinence ( n=9) and post-prostatectomy incontinence ( n=13). Preoperative daily pad usage was 3.5±1.0. The impact of incontinence on the quality of life (QOL)measured by the visual analogue scale (VAS)was 7.1±1.2. All 46 patients underwent artificial urethral sphincter implantation, of which 20 patients were treated with anticholinergic drugs (5 cases) or urinary tract related surgery (urethral stenosis incision in 2 cases, sphincterectomy in 3 cases, urethral dilation in 5 cases, urethral calculus lithotripsy in 1 case, and augmentation cystoplasty in 4 cases) before artificial urethral sphincter implantation. Of the 45 male patients, 25 patients had the transperineal approach and 20 had the trans-scrotal approach. The female case had a trans-retropubic approach. Different cuffs size was used based on individual circumference of bulbar urethra (45 male cases: 4.5cm in 16 cases, 4.0cm in 29 cases; one female case: 8.0cm). Long-term surgical efficacy was evaluated. Assessments included postoperative urinary continence (socially continent: one pad per day or less; complete dry: wearing no pads), artificial urinary sphincter status and complications. The influences of patients of different etiologies, surgical approaches and cuff size on surgical results were compared. Results:The mean follow-up time was 7.1 years ranged from 6 months to 19 years. At the latest visit, 32 patients (69.6%) maintained the primary functional artificial urinary sphincter. Three patients (6.5%) had artificial urinary sphincter revisions and maintained continence with the new device. 11 patients (23.9%) removed the artificial urinary sphincter because of post-complications. Thirty-five patients were socially continent, of which 16 patients were totally dry, leading to the overall social continent rate as 76.1%(35/46). There was a significant reduction in pad usage to 1.2±0.6 diapers per day ( P<0.001). The impact of incontinence on the QOL measured by the VAS dropped to 2.6±1.9 ( P<0.001). The complication rate was 32.6%(15/46), including infections ( n=4), erosions ( n=5), mechanical failure ( n=3), dysurie ( n=2) and urethral atrophy ( n=1). There were no significant differences in social continent rate between patients with different etiologies[75.0%(18/24)vs. 66.7%(6/9) vs. 84.6%(11/13)], perioperative complications [37.5%(9/24)vs. 33.3%(3/9) vs. 23.1%(3/13)] and device re-intervention rate[37.5%(9/24) vs. 33.3%(3/9)vs. 15.4%(2/13)]. There were no statistically significant differences in postoperative complete dry rate [32%(8/25)vs. 40%(8/20), P=0.76] and postoperative device failure free rate [60%(15/25)vs. 80%(16/20), P=0.20] between trans-perineal group and trans-scrotal group. There was no statistically significant difference in postoperative social continent rate between 4.5cm cuff and 4.0 cuff[75%(12/16) vs. 65.5%(19/29), P=0.74]. Conclusions:Artificial urethral sphincter implantation is an effective treatment for stress urinary incontinence due to intrinsic sphincter deficiency. There was no difference in the continent rate and complication rate between patients of different etiologies, different surgical approaches and cuff size selection.

ABSTRACT

Objective:To investigate the long-term efficacy and complications of augmentation uretero-enterocystoplasty (AUEC).Methods:The clinical data of 262 patients with lower urinary tract dysfunction who underwent AUEC at our center from January 2003 to June 2022 were analyzed retrospectively. There were 193 males and 69 females, the median age was 24 (4, 67) years, the median disease duration was 12.0 (0.2, 56.0) years and the preoperative creatinine was 91.5 (68.1, 140.0) μmol/L. 320 ureters had high-grade UUTD, 216 ureters had VUR, 14 of which had low-pressure reflux.The number of low-grade VUR ureter was 22 (10.2%) and the number of high-grade VUR ureter was 194 (89.8%). Video-urodynamics showed that the maximum bladder capacity was 102 (47, 209) ml, the maximum detrusor pressure was 33.0 (15.5, 50.5) cmH 2O, and the bladder compliance was 6.4 (3.0, 12.3) ml/cmH 2O. All patients underwent AUEC. The surgical method is to cut a segment of sigmoid colon, open the sigmoid colon along the mesenteric margin, fold and suture it into " U" or " S" shaped intestinal mesh according to the principle of " detubulization" . At the same time, perform ureteroplasty and replanting, and then anastomosis the intestinal mesh with the opened bladder flap to form an expanded new bladder. Follow-up was performed via outpatient clinic or telephone. The creatinine, maximum bladder capacity, maximum detrusor pressure, bladder compliance, ureteral reflux and upper urinary tract dilatation were compared preoperatively and postoperatively. The postoperative complications were also evaluated. Results:The median follow-up time was 57.4 (4, 151) months after surgery. At 1-3 months after surgery, the maximum bladder capacity and bladder compliance increased to 303.9% and 189.9% of the preoperative level, and the maximum detrusor pressure decreased to 63.6% of the preoperative level. At 6-10 years after surgery, the maximum bladder capacity and bladder compliance increased to 490.2% and 627.9% and the maximum detrusor pressure decreased to 25.8% of the preoperative level. The UUTD of the patients was significantly reduced after surgery. The number of the high grade UUTD decreased to 116 (116/398, 29.2%) at 1-3 months and 51 (51/274, 18.6%) at 4-6 months. At 6-10 years, the number of the high-grade UUTD decreased to 4 (4/76, 5.3%) ( P<0.001), which was significantly lower than that before operation. The VUR was significantly relieved after operation, and 393 ureters had no VUR at 1-3 months, accounting for 97.8% (393/402) of the total ureters. Sustained remission of VUR was observed during follow-up. 73 ureters had no VUR at 6-10 years, accounting for 96.1% (73/76) of total ureters ( P<0.001). Patients' creatinine decreased to 79.0 (65.0-128.2) μmol/L at 1-3 months postoperatively, with a downward trend but no statistical difference, and creatinine levels were not significantly elevated at any postoperative time point compared with preoperative levels ( P>0.05). Postoperative complications included metabolic acidosis in 26 cases (9.9%), vesicoureteral anastomosis stenosis in 15 cases (5.7%), recurrent urinary tract infection in 16 cases (6.1%), and urinary calculi in 20 cases (7.6%), and intestinal obstruction requiring laparotomy in 8 cases (3.1%), all of them could be improved after treatments. Conclusions:AUEC is a safe and effective method for treating high-grade VUR or VUR with impaired anti-reflux mechanism, high-grade UUTD or UUTD with ureteral or vesicoureteral junction obstruction, and all of the complications can be improved after treatment. This technique can increase the bladder capacity and compliance, reconstruct the anti-reflux mechanism, and release upper urinary tract obstruction. It may play an important role in stabilizing and protecting the residual renal function from further deterioration.

ABSTRACT

Objective:To investigate the effect of N-acetylcysteine (NAC) on endoplasmic reticulum stress (ERS) and oxidative stress(OS) induced by tunicamycin (Tm) and its mechanism.Methods:Mouse derived brain microvascular endothelial cells cultured in vitro were divided into control group (normal cell culture), TM group (cells were intervened with 5 μg/mL Tm for 24 h), NAC + TM group (cells were pretreated with 1 mmol/L NAC for 1 h, then were intervened with 5 μg/mL Tm for 24 h) and NAC group (cells were intervened with 1 mmol/L NAC for 24 h) according to different intervention methods.CCK-8 and FITC-Annexin V/PI were used to detect the survival rate and apoptosis rate of cells.Western blot was used to detect the expression of GRP78、CHOP、p-eNOS and caspase-12 protein. Laser confocal microcopy was used to detect the expression of ROS, and colorimetry was used to detect the activity of MDA and SOD.Results:There were significant differences in apoptosis rate and survival rate among the four groups ( F=62.57, 35.00, both P<0.05). The apoptosis rate of TM group ((25.49±1.55)%) was higher than that of Control group ((13.76±1.48)%)( P<0.01), while the apoptosis rate of NAC+ TM group ((17.65±1.00)%) was lower than that of TM group ( P<0.01). The survival rate of TM group ((66.33±5.69)%) was lower than that of Control group ((100.00±2.12)%)( P<0.01), while the survival rate of NAC+ TM group ((85.67±4.04)%) was higher than that of TM group ( P<0.01). Western blot showed that there were significant differences in the expression levels of GRP78、CHOP and p-eNOS among the four groups ( F=32.39, 68.66, 13.12, all P<0.01). The expression levels of GRP78 and CHOP protein in TM group were higher than those of Control group (both P<0.05), while the expression level of p-eNOS was lower than that of Control group ( P<0.01). The expression levels of GRP78 and CHOP protein in NAC+ TM group were lower than those of TM group (both P<0.05), while the expression level of p-eNOS was higher than that of TM group ( P<0.01). There was no significant difference in the expression level of caspase-12 protein among the four groups ( F=0.33, P>0.05). Laser confocal showed that there was significant difference in the average fluorescence intensity of ROS among the four groups ( F=77.66, P<0.01). The average fluorescence intensity of ROS in TM group (32.67±1.53) was higher than that in Control group (12.67±2.08) and NAC+ TM group (18.33±1.53) (both P<0.01). Colorimetry showed that there were significant differences in the activity of SOD and the concentration of MDA among the four groups ( F=40.53, 34.99, both P<0.01). The results of colorimetry showed that the activity of SOD in TM group((41.60±1.53)U/mg) was lower than that in Control group((65.39±4.60)U/mg) and NAC+ TM group((58.72±1.64)U/mg)(both P<0.01). The concentration of MDA in TM((2.27±0.11)μmol/mg) group was higher than that in Control group((1.39±0.13)μmol/mg) and NAC+ TM group((1.44±0.11)μmol/mg) (both P<0.01). Conclusion:NAC can reduce Tm-induced apoptosis of cerebral micro-vascular endothelial cells, which may be related to its inhibition of ERS/ OS-related pathways.

ABSTRACT

Objective:To investigate the changes of default network functional connectivity (FC) in resting state of patients with insomnia disorder (ID).Methods:Fifty-six patients with insomnia disorder and fifty healthy controls were recruited. All subjects were assessed with Pittsburgh sleep quality index (PSQI), insomnia severity index (ISI), Epworth sleepiness score (ESS) and Hamilton depression scale (HAMD-17). All subjects were scanned with resting state functional magnetic resonance imaging (rs-fMRI). SPM12 and CONN18b were used to preprocess rs-fMRI data on MATLAB (R2013b).The medial superior frontal gyrus was defined as the seed point, and the differences in the functional connection strength of the two groups of subjects were compared. Pearson correlation analysis was performed between the FC value of the brain area with statistical significance and scores of PSQI and ISI.Results:(1)FC analysis showed that compared with the control group, patients with ID had abnormal default mode network (DMN) connection, as follows: FC of left medial superior frontal gyrus and left central anterior gyrus (MNI: x, y, z=-30, -15, 51) and anterior cingulate gyrus (MNI: x, y, z=-6, 24, 36), FC of right medial forehead between the last gyrus and the left central anterior gyrus (MNI: x, y, z=-48, -6, 48), FC of left anterior cuneiform and the left central back (MNI: x, y, z=-54, -18, 54) and left superior occipital gyrus (MNI: x, y, z=-21, -69, 30), FC of right precuneus and left central posterior gyrus (MNI: x, y, z=-60, -21, 48) was enhanced. The FC of left anterior cuneiform lobe and the right middle frontal gyrus (MNI: x, y, z=42, 33, 42) and the right angular gyrus (MNI: x, y, z=54, -51, 45), FC of right precuneus and left inferior temporal gyrus (MNI: x, y, z=-51, -12, -42) was weakened. (2)With the left medial superior frontal gyrus as the seed point, FC values in anterior cingulate gyrus ( r=0.451, 0.338, both P<0.01) and left anterior central gyrus ( r=0.324, 0.402, both P<0.05) were positively correlated with PSQI and ISI scores. With the right precuneus as the seed point, FC value of left posterior central gyrus was positively correlated with PSQI( r=0.333, P=0.013) and ISI scores( r=0.418, P=0.008), while FC value of left inferior temporal gyrus was negatively correlated with PSQI( r=-0.662, P=0.001) and ISI scores( r=-0.402, P<0.01).With the left precuneus as the seed point, FC value of left superior occipital gyrus was positively correlated with PSQI( r=0.438, P=0.001) and ISI scores( r=0.495, P=0.011). Conclusion:Patients with ID may have changes in the functional connection of multiple networks. The decrease of FC in DMN may be one of the potential causes of insomnia. The increase in FC between DMN and the visuospatial attention network may be the core of the mechanism of damage to the brain function network of insomnia link.

ABSTRACT

【Objective】 To compare the enhancement effects of lean body weight (LBW) and total body weight (TBW) as indexes to calculate the contrast agent dosage under the condition of energy spectrum CT scanning. 【Methods】 A total of 218 patients who received liver enhancement CT from November 2018 to January 2019 were enrolled in this study. There were 101 patients in LBW group and 117 patients in TBW group. Both groups were scanned by energy spectrum CT, and the parameters of scanning and reconstruction were identical. The contrast agent dose was 500 mgI/kg (LBW) in LBW group and 450 mgI/kg (TBW) in TBW group, and the injection rate was 2.8 mL/s. Images were transferred to a GE AW4.7 workstation and the 50 keV monochromatic images were analyzed. We compared the dosage of contrast medium, CT value of aorta in arterial phase (HU-aorta), hepatic enhancement CT value in venous phase (-liver), the rate of reaching the enhancement standard and variability in the two groups. 【Results】 Compared with TBW group, LBW group had lower contrast agent dosage, HU-aorta and ∆-liver (P0.05). The variation rate of HU-aorta and ∆-liver in LBW group was lower than that in TBW group. Using LBW as an index to calculate the dosage of liver enhanced CT also made the enhancement of liver parenchyma more consistent in different patients. 【Conclusion】 Even on the premise of energy spectrum CT scanning, using LBW-based contrast injection in liver enhanced CT can not only reduce contrast dose, but also make the enhancement in liver parenchyma more consistent among different patients.

ABSTRACT

OBJECTIVE@#To investigate the expression of DNMT3b in human bladder cancer tissues and its correlation with postoperative survival of patients with bladder cancer.@*METHODS@#Thirty-eight pairs of surgically resected human bladder cancer tissues and adjacent bladder tissues were detected by immunohistochemistry for DNMT3b expression, and the correlations of DNMT3b expression level were analyzed with the patients'age, gender, pathological grade, tumor size, T stage, lymph node metastasis and TNM stages. Kaplan-Meier survival analysis was performed to assess the effect of DNMT3b expression on survival outcomes of the patients.@*RESULTS@#High DNMT3b protein expression was detected in 63.16% of the bladder cancer tissues and in 13.16% of the adjacent tissues ( < 0.05). The expression level of DNMT3b was associated with the pathological grade (=0.002), tumor size ( < 0.001), T stage ( < 0.001), lymphatic metastasis (=0.039) and TNM stage ( < 0.001), but not with gender or age of the patients. Multivariate logistic regression analysis showed that the protein expression level of DNMT3b was correlated with tumor size (=0.008) and TNM grades of the tumor (=0.042). Kaplan-Meier analysis showed that the patients with a high DNMT3b expression had a significantly shorter overall survival than those with a low DNMT3b expression (=0.021).@*CONCLUSIONS@#DNMT3b overexpression in bladder cancer is closely related to such clinicopathological factors as pathological grade, tumor size, T stage, lymphatic metastasis, and TNM stage and a shorter overall survival of the patients, suggesting the potential value of DNMT3b as a prognostic marker and a new therapeutic target for bladder cancer.

ABSTRACT

Objective:To evaluate the role of spinal peroxisome proliferation-activated receptor-γ (PPAR-γ) in protectin D1 (PD1)-induced reduction of neuropathic pain (NP) in rats.Methods:Forty-eight clean-grade healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 200-250 g, were divided into 4 groups ( n=12 each) by a random number table method: sham operation group (Sham group), NP group, NP plus PD1 group (NP+ PD group), and NP plus PD1 plus GW9662 group (NP+ PD+ GW group). Neuropathic pain was induced by spared nerve injury in anesthetized rats.In NP+ PD and NP+ PD+ GW groups, PD1 900 ng (diluted to 20 μl in dimethyl sulfoxide [DMSO]) was intrathecally injected once a day for 8 consecutive days starting from 30 min before establishing the model.In NP+ PD+ GW group, the PPAR-γ antagonist GW9662 200 ng (diluted to 20 μl in DMSO) was intrathecally injected once a day for 8 consecutive days starting from 45 min before establishing the model.The equal volume of DMSO was intrathecally injected in Sham group.The mechanical paw withdrawal threshold (PWT) was measured before establishing the model and at 1, 3, 5, 7, 10 and 14 days after establishing the model.Six rats in each group were sacrificed on day 14 after establishing the model, and their lumbar enlargements were removed for determination of the expression of PPAR-γ, TNF-α and IL-6 by Weston blot.Six rats in each group were sacrificed on day 14 after establishing the model, L 4, 5 segments of the spinal cord were removed, and the co-expression of PPAR-γ with neuron-specific nucleoprotein (NeuN), glial fibrillary acidic protein (GFAP) or serum calcium binding adapter molecule 1 (Iba-1) was determined by immunofluorescence staining. Results:Compared with group Sham, PWT was significantly decreased at each time point after establishing the model, the expression of PPAR-γ was down-regulated, and the expression of TNF-α and IL-6 was up-regulated in the other three groups ( P<0.05). Compared with group NP, PWT was significantly increased at 7-14 days after establishing the model, the expression of PPAR-γ was up-regulated, and the expression of TNF-α and IL-6 was down-regulated in group NP+ PD, and no significant change was found in the parameters mentioned above in group NP+ PD+ GW ( P>0.05). Compared with group NP+ PD, PWT was significantly decreased at 7-14 days after establishing the model, the expression of PPAR-γ was down-regulated, and the expression of TNF-α and IL-6 was up-regulated in group NP+ PD+ GW ( P<0.05). The results of immunofluorescence staining of the spinal cord showed that PPAR-γ was co-expressed with NeuN and GFAP. Conclusion:The mechanism by which PD1 mitigates NP is related to promoting the activation of PPAR-γ in spinal cord neurons and astrocytes and inhibiting inflammatory responses in rats.

ABSTRACT

Objective: To preliminary explore the effect of decellularized adipose tissue (DAT) combined with vacuum sealing drainage (VSD) on wound inflammation in pigs. Methods: The DAT was prepared through the process of freeze-thaw, enzymatic digestion, organic solvent extraction, and vacuum freeze-drying. The appearance of DAT was observed before and after freeze-drying. HE staining was used to observe its structure and acellular effect. Eighteen male Bama minipigs were recruited, and four dorsal skin soft tissue wounds in diameter of 4 cm were made on each pig and randomly divided into 4 groups for different treatments. The wounds were treated with DAT combined with VSD in DAT/VSD group, DAT in DAT group, VSD in VSD group, and sterile gauze dressing in control group. HE staining was performed at 3, 7, 10, and 14 days after treatment. Moreover, the expressions of inflammatory factors [interleukin 1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α)], as well as the phenotypes of M1 and M2 macrophage phenotypic markers [inducible nitric oxide synthase (iNOS) and arginase 1 (ARG-1)] were detected by real-time fluorescence quantitative PCR (qRT-PCR). ELISA was used to determine the content of iNOS and ARG-1. Results: General observation and HE staining showed that DAT obtained in this study had a loose porous structure without cells. The neutrophils of wounds were significantly less in DAT/VSD group than in control group and DAT group ( P0.05) between DAT/VSD group and VSD group. And the neutrophils were significantly less in DAT/VSD group than in other three groups ( P<0.05) at 7, 10, and 14 days. The mRNA expressions of IL-1β, IL-6, TNF-α, and iNOS were significantly lower in DAT/VSD group than in other three groups at 3, 7, 10, and 14 days ( P<0.05), while the mRNA expression of ARG-1 was significantly higher in DAT/VSD group than in other three groups ( P<0.05). ELISA showed that the content of iNOS was significantly lower in DAT/VSD group than in other three groups at 3, 7, 10, and 14 days ( P<0.05), while the content of ARG-1 was significantly higher in DAT/VSD group than in other three groups ( P<0.05). Conclusion: DAT combined with VSD can significantly reduce inflammatory cell infiltration during wound healing, regulate the expressions of inflammatory factors and macrophage phenotype, and the effect is better than single use of each and conventional dressing change.

ABSTRACT

ObjectiveTo investigate the effect of longitudinal trajectories of body mass index (BMI) on new-onset gallstone disease. MethodsA prospective cohort study was conducted for 44168 employees who underwent physical examination in Kailuan General Hospital in 2006, 2008, and 2010, and related data, including BMI, were collected. Physical examination was performed once every two years, and the employees were followed up to observe the onset of gallstone disease. According to the longitudinal trajectories of BMI, the employees were divided into low-stable group with 14888 employees, medium-stable group with 22334 employees, and high-stable group with 6948 employees. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between multiple groups; the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to calculate the cumulative incidence rate of gallstone disease in each group, and the log-rank test was used for comparison between groups. The Cox proportional-hazards regression model was used to analyze the influence of longitudinal trajectories of BMI on the onset of gallstone disease. Resultsthe mean follow-up of 5.41 years, a total of 902 patients with gallstone disease were observed, and the cumulative incidence rates of gallstone disease in the low-stable group, the medium-stable group, and the high-stable group were 4.80%, 5.25%, and 9.45%, respectively, with a significant difference between groups based on the log-rank test (χ2=81.86, P<0.01). After adjustment for confounding factors in the Cox proportional hazards model, compared with the low-stable group, the medium-stable group and the high-stable group had a risk of gallstone disease increased by 1.55 times (95% confidence interval[CI]: 1.31-1.84) and 2.29 times (95% CI: 1.86-2.80), respectively. ConclusionThe ncreased longitudinal trajectory of BMI is an independent risk factor for the onset of gallstone disease.
