ABSTRACT

Five patients with mediastinal bronchogenic cyst (MBC) were treated with endoscopic submucosal tunnel dissection (ESTD) between January 2018 and October 2019 at the Department of Gastroenterology in Henan Provincial People′s Hospital. Lesions were located in the middle or lower esophageal level, with diameters≤3.5 cm. The tunnel establishment time was 13-18 min, and the tumor stripping time was 30-51 min. The number of titanium clips used for tunnel closure was 5-8. The tumors were completely resected. No major bleeding or hypoxemia occurred during the operation and no serious adverse reactions occurred after the operation. Postoperative pain scores were all ≤3. The hospital stay was 4-7 days. There was no tumor residue and recurrence during 4-23 months of follow-up.It is suggested that ESTD for MBC which derived from post mediastinum and located at the lower or middle level esophagus is safe and effective.

ABSTRACT

Objective:To analyze the changes in biological characteristics including infectivity, growth and pathogenicity of Chlamydia muridarum ( Cm) after serial passage in vitro in special conditions in order to provide reference for screening attenuated live vaccines and virulence-related genes. Methods:Wild-type Cm strain (G0) was cultured for several passages using conventional cell culture method under alternate unassisted and assisted culture conditions. Then, the 28th generation (G28) of Cm was selected and compared with the parental G0 strain in terms of centrifugation dependence, attaching ability, intracellular growth curve, plaque size and fallopian tube lesions after genital tract infection in a mouse model. Results:Compared with the parental G0 strain, the G28 strain showed significantly decreased dependence on centrifugation during cell infection ( P<0.05) and increased attachment capacity to cells ( P<0.05). No significant differences were observed in the growth curves 32 h after cell infection or in the plaque sizes between the parental G0 and G28 strains. In the in vivo virulence test, fallopian tube lesions were observed in 87.5% of G0-infected mice and 37.5% of G28-infected mice ( P<0.05). Conclusions:Compared with the parental G0 strain, the G28 strain showed significantly enhanced in vitro infection ability, but decreased in vivo pathogenicity, which brought hope for further identification of virulence genes, isolation of attenuated strains with single genotype and development of live attenuated Chlamydia vaccines.

ABSTRACT

Objective:To evaluate the effects of stellate ganglion block (SGB) on the activation of M1 microglia during cerebral ischemia-reperfusion (I/R) in rats.Methods:Fifty-four SPF healthy male Sprague-Dawley rats, aged 8-10 weeks, weighing 240-270 g, were divided into 3 groups ( n=18 each) using a random number table method: sham operation group (group Sham), cerebral I/R group (group IR) and SGB group.Blood vessels were only exposed, without occlusion in group Sham.Cerebral I/R was induced by occlusion of the middle cerebral artery for 90 min followed by reperfusion in group IR.Cervical sympathetic trunk transaction was performed to induce left SGB immediately after onset of reperfusion in group SGB.Blood samples were collected from the apex of the heart at 6, 12 and 24 h of reperfusion for determination of the concentrations of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β in the serum (using enzyme-linked immunosorbent assay). The animals were sacrificed after the neurological function was evaluated at 24 of reperfusion, and brain tissues were removed for microscopic examination of the pathological changes in cortex, for determination of percentage of cerebral infarct size (by TTC staining), for assessment of cell apoptosis and apoptosis rate in cortex (by TUNEL), and for determination of the expression of microglial biomarker Iba-1 and activated M1 microglia biomarker CD68 (by Western blot). Results:Compared with group Sham, the neurological function score, percentage cerebral infarct size, apoptosis rate in cortex, concentrations of TNF-α, IL-6 and IL-1β in the serum, and the expression of Iba-1 and CD68 were significantly increased in IR and SGB groups ( P<0.05). Compared with group IR, the neurological function score, percentage cerebral infarct size, apoptosis rate in cortex, concentrations of TNF-α, IL-6 and IL-1β in the serum, and the expression of Iba-1 and CD68 were significantly decreased in group SGB ( P<0.05), and the pathological changes of brain tissues were significantly attenuated in group SGB. Conclusion:The mechanism by which SGB reduces cerebral I/R injury is related to inhibiting activation of M1 microglia in rats.

ABSTRACT

Objective:To culture and identify dermal mesenchymal stem cells (DMSCs) in skin lesions of patients with psoriasis, and to determine the expression of hairy and enhancer of split-1 (HES1) and chemokine ligand 6 (CXCL6) in DMSCs.Methods:DMSCs were isolated from skin lesions of 15 patients with psoriasis and normal skin tissues of 18 healthy controls, and then subjected to culture. Cell phenotypes were identified by flow cytometry, and mRNA and protein expression of HES1 and CXCL6 was determined by real-time fluorescence-based quantitative PCR (RT-PCR) and Western blot analysis respectively. Comparisons were performed between 2 groups by using t test. Results:There was no difference in the morphology of DMSCs between the psoriasis group and control group. The mRNA expression of HES1 and CXCL6 in the psoriasis group was 3.56 and 3.44 times that in the control group respectively, and there was a significant difference between the two groups (both P < 0.05) . The protein expression of HES1 and CXCL6 in DMSCs was significantly higher in the psoriasis group than in the control group (both P < 0.05) . Conclusion:The high expression of HES1 and CXCL6 in DMSCs from lesions may be involved in the occurrence of psoriasis.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is well known as a chronic lung disease. In recent years, with the deepening of its understanding, various complications of COPD, especially pulmonary hypertension(PH) have received more and more attention. COPD patients with PH have an increased fatality rate and a poor prognosis, which seriously affects the quality of life of the patients, and the treatment of the disease lacks effective drugs. In order to fully understand the current status of the treatment of the disease, the research progress of the drug treatment of COPD combined with PH was reviewed. The results show that for patients with COPD and PH, the best treatment should be given to their underlying diseases. The use of statins and fasudil may be beneficial, but the effect of targeted drugs is still controversial. In the future, more large randomized controlled trials need to be carried out to further clarify the efficacy of various drugs on COPD.

ABSTRACT

Objective To explore the molecular pathological mechanism of gout, and to explore the mechanism of how interleukin (IL)-37 influencing PDZK1 protein in gout through nuclear factor κB (NF-κB) pathway. Methods HK-2 cells were stimulated with inflammatory signal IL-37. The expression of PDZK1 and its subcellular localization were detected by real-time fluorescence quantitative polymerase chain reaction (real-time PCR) at different concentrations of IL-37 (defined as group A), PDTC+IL-37 (defined as group B), Wortmannin+IL-37 (defined as group C), respectively.The changes of PDZK1 protein expression in HK-2 cells were detected by adding inhibitor PDTC (NF-κB pathway inhibitor) or Wortmannin (PI3K pathway inhibitor) and inflammatory signal stimulating protein imprinting method. The comparative t test was used for statistical analysis between groups A, B and A and C. Results The average levels of PDZK1 mRNA were as follows:(group A: 28.71 ±0.35, 28.57 ±0.31, 28.78 ±0.28, 28.63 ±0.29, 28.62 ±0.19; group B: 28.71 ±0.31, 28.83 ±0.27, 28.58±0.26, 28.73±0.36, 28.68±0.35;group C:28.81±0.32, 28.91±0.29, 28.72±0.24, 28.59±0.18, 28.58±0.22). There was no significant change in PDZK1 mRNA level in group A and B. The same IL-37 was found in group A and B. The values of T were 5.73, 4.72, 4.69, 5.86 and 6.79, respectively. The P values were all greater than 0.05, and there was no significant difference between the two groups. The values of T were 6.78, 7.13, 7.47, 6.38 and 5.98 in the same IL-37 concentration groups of A and C, respectively, and the P values were all greater than 0.05, with no significant difference. The levels of PDZK1 protein in the three groups by Western blot analysis were as follows: (group A: 0.200±0.082, 0.412±0.032, 0.723±0.063, 1.202±0.021, 1.222±0.023;group B: 0.124±0.064, 0.303±0.081, 0.325±0.062, 0.223±0.071, 0.343±0.052; group C: 0.017±0.022, 0.204± 0.015, 0.187±0.053, 0.302±0.051, 0.404±0.051), The levels of PDZK1 protein in group A treated with different concentrations of IL-37 followed by the concentration of IL-37. The level of PDZK1 protein in group B increased with the increase of IL-37 concentration, but the level of PDZK1 protein in group B was lower than that in the group treated with IL-37 only, and decreased when the concentration of IL-37 was 40 ng/ml.The level of PDZK1 protein in group C increased with the increase of IL-37 concentration, but the level of PDZK1 protein in group C was lower than that in the group treated with IL-37 only, and the same concentration of IL-37 in group A and B. The values of T were 1.83, 1.37, 1.64, 1.57 ,1.49, with P values greater than 0.05. There was no significant difference between the two groups. The values of T were 1.28, 1.37, 1.26, 1.42, 1.39 in the same concentration of IL-37 in group A and C, with P values greater than 0.05, with no significant difference.The results of immunofluorescence analysis showed that the trend of the three groups was basically consistent with that of Western-Blot. Conclusion The pathogenesis of gout induced by IL-37 through PDZK1 protein may not occur at the transcriptional level, but may occur at the level of protein translation.

ABSTRACT

Objective@#To study the tissue size, calcification characteristics and the correlation between calcification and age and lateral side of 6, 7 and 8 costal cartilage in women, so as to provide reference for clinical application.@*Methods@#From the radiology storage center of Second Xiangya Hospital, 70 cases of female costal cartilage were treated with dual-source CT three-dimensional reconstruction. The reconstructed images were treated with maximum intensity projection (MIP) and volume reconstruction (VR). The length, width and thickness of bilateral 6, 7 and 8 costal cartilage were measured by VR images, and the correlation between calcification rate, calcification degree, calcification type, calcification location, calcification with age and side was observed and analyzed on VR and MIP images. The data were analyzed by SPSS 20.0 and compared by corresponding statistical method, including independent sample t test, chi-square test, logistic regression analysis and variance analysis.@*Results@#(1) The length of costal cartilage on the left was (98.7 ±12.7) mm, (132.8 ±13.8) mm, (81.5 ±11.6) mm, width (12.6 ±1.5) mm, (11.0 ±1.4) mm, (7.4 ±1.1) mm, thickness (8.1 ±0.5) mm, (7.7 ±0.6) mm, (6.6 ±0.6) mm. On the right side, the length of costal cartilage was (95.8 ±11.3) mm, (133.1 ±12.0) mm, (81.7 ±12.3) mm, width (12.2 ±1.4) mm, (11.11 ±1.5) mm, (7.4 ±1.1) mm, thickness (8.2 ±0.6) mm, (7.7 ±0.5) mm, (6.5 ±0.6) mm. There was no significant difference in the length, width and thickness of the left and right sides of the costal cartilage in the same sequence (P>0.05). There were significant differences in length, width and thickness between unilateral costal cartilage with different ordinal numbers (P<0.01). (2) The total calcification rates of left and right costal cartilage were 61.9% (130/210) and 60.0% (126/210), respectively, and there was no significant difference between the two groups (The chi-square was equal to 0.160. The P value was equal to 0.689), but there was no significant difference in left and right total calcification types, total calcification location and total calcification count (P>0.05). There was no significant difference in the total calcification type between left and right, the total calcification location and the total calcification degree count (P>0.05). There was also no significant difference between the two groups (P>0.05). There was no significant difference in the calcification rate between the left and right sides of the 6th, 7th and 8th costal cartilage, but there was significant difference in the total calcification types of the 6th, 7th and 8th costal cartilage (The chi-square was equal to 61.541, P value was less than 0.001). (3)The relationship between calcification rate and age was analyzed by univariate analysis and logistic regression equation. The higher the age, the higher the calcification rate. The relationship between the calcification degree and age of the 6th, 7th and 8th costal cartilage was tested by variance test, and the regression equation showed that the calcification degree of the 6th, 7th and 8th costal cartilage was higher with the age.@*Conclusions@#Preoperative three-dimensional reconstruction and image post-processing of costal cartilage with dual-source CT can accurately measure the amount of cartilage tissue and define the characteristics of calcification, so as to guide the clinical selection of costal cartilage that meets the requirements of operative method. In female patients of different ages undergoing rhinoplasty and external ear reconstruction, the calcification rate of costal cartilage increased with age, but there was no positive correlation. With the increase of calcification with age, artificial materials can be used for cases with severe calcification to avoid the blindness of surgery.

ABSTRACT

Objective@#To explore the anatomy and clinical application of stepladder V-Y advanced flaps based on the lateral calcaneal artery perforator.@*Methods@#Twenty-four lower extremities from 12 adult cadavers were dissected to investigate the perforators emerging along the lateral edge of the achilles tendon, in terms of amount and distribution, relative to the tip of the lateral malleolus. Based on the anatomical findings, stepladder V-Y advanced flaps, based on the perforator(s) of the lateral calcaneal artery (LCA) or the peroneal artery (PA), were used for reconstruction of lower-posterior heel defects in 22 cases.@*Results@#Twenty-four lower extremities from 12 adult cadavers were successfully dissected. The peroneal artery continued to be the lateral calcaneal artery at the level of (6.0±1.4) cm above the tip of the lateral malleolus. Both of them have the perforators distributed to the skin in the achilles tendon area. In the space from the tip of the lateral malleolus to 8.0 cm and above, a total of 71 perforators with diameter larger than 0.5 mm were found in all extremities. Among them, 9%(7/71) were originated from peroneal artery, and 91%(64/71) were the lateral calcaneal artery. In the 22 cases of clinical application, the pedicle of flaps were used, based on the perforator of lateral calcaneal artery and (or) peroneal artery. The size of flaps ranged from 3.5 cm×9.0 cm to 5.0 cm×10.0 cm.There were 3 cases of skin necrosis at the tip of the flap, which were healed after dressing change. The other flaps had completely survived, and the wound healed in the first stage. Follow-up last for 8-24 months after operation. All patients had well recovery of ankle flexion, extension and appearance. They were able to weight-bearing walk, with natural gait. The texture and sensation of the flaps were similar to that of the surrounding skin. There were few obvious scar or contracture deformity. The functional recovery was satisfied.@*Conclusions@#The blood supply in the achilles tendon region is mainly from the lateral calcaneal artery, and partly from the peroneal artery. Stepladder V-Y advanced flap based on the lateral calcaneal artery perforator can be used with reliable blood supply and sensation reconstruction, which is a good choice to repair small to medial wounds in heel area.

ABSTRACT

OBJECTIVE:To develop a method for rapid determination of moisture and salidroside in Rhodiolae crenulatae.METHODS:The content of moisture was determined by the methods of oven drying (as reference value);the content of salidroside was determined by HPLC (as reference value).Near infrared spectroscopy (NIR) combined with partial least squares (PLS) algorithm were adopted to establish quantitative model for the contents of moisture and salidroside.According to reference value,83 samples were collected for preprocessing spectra by Savitsky Golay with second derivative and Norris Derivative with first derivative.The optimal spectrum range of moisture and salidroside were 7 343.60-6 865.34,5 183.72-4 890.59 cm-1 and 7 050.47-4 327.48 cm-1,respectively.RESULTS:The content determination methodology of salidroside was in line with the requirement.The correlation coefficients of calibration for moisture and salidroside were 0.968 9 and 0.920 3,and the root mean square errors of calibration were 0.273 0 and 0.085 0,respectively.The correlation coefficients of predication were 0.977 1 and 0.930 0,and the root mean square errors of prediction were 0.222 0 and 0.075 5,respectively.CONCLUSIONS:The method is proved to be simple,rapid,non-destructive and accurate,which can be used for the rapid determination of moisture and salidroside in R.crenulatae.

ABSTRACT

Objective To evaluate the clinical value of 6 androgens in the serum of Sj?gren's syndrome (SS) measured by liquid chromatography tandem mass spectrometry (LC-MS).Methods 32 SS patients (SS group) and 25 healthy people (healthy group) were included in this study.6 androgens in the serum were analyzed by LC-MS after prepared.PCA,PLS-DA models and t-test were used to class differentiation of androgens between two groups.Results The results of PLS-DA showed that SS group and healthy group could be well classed by 6 androgens.The levels of testerone (T),dihydrotestosterone (DHT),dehydroepiandrosterone (DHEA),androsterone and DHEAS in SS group were significantly lower than those in healthy group (t=8.536,2.438,3.172,4.158,4.489,all P<0.05).The samples before or after menopause could be distinguished between the two groups by PLS-DA.Conclusion The significant difference of androgens was discovered between SS patients and healthy people via the measurement of 6 androgens in serum.It may arise a new idea for diagnosis and treatment of SS.

ABSTRACT

AIM To prepare the moisture-proof granules of polysaccharides from Astragali Radix.METHODS Mixture design was adopted in the optimization of excipient proportion after moisture absorption determination of mixed powder of polysaccharides and seven excipients.With the influencing factors of ethanol concentration,ethanol amount,drying temperature and drying time,together with the evaluation indices of moisture absorption rate and non-forming rate,the preparation was optimized by orthogonal test based on single factor test.The critical relative humidities were then compared after drawing moisture absorption curves of polysaccharides,mixed powder and granules.RESULTS The mixed powder with an optimal ratio (1 ∶ 2) of polysaccharides to mixed excipients (46.3% lactose,14.5% mannitol and 39.2% microcrystalline cellulose) was found to remain the moisture absorption rate of 11.6% within 168 h.The optimal conditions were determined to be 70% for ethanol concentration,0.125 times for ethanol amount,55 ℃ for drying temperature,and 60 min for drying time,the moisture absorption rate was 8.1% within 168 h,and the non-forming rate was 11.46%.Compared with polysaccharides and mixed powder,the granules showed relatively lower initial velocity and acceleration (absolute value) of moisture absorption,and relatively higher critical relative humidity.CONCLUSION The granules of polysaccharides from Astragali Radix prepared by this method show a good moisture-proof effect.

ABSTRACT

Objective: To investigate the relationship between blood triglyceride (TG) level and brachial-ankle pulse wave velocity (baPWV) in relevant population. Methods: A total of 22622 participants in Kailuan area were enrolled and divided into 4 ranks: Stroke rank, n=5219, Aged rank n=1754, Pregnancy hypertension Rank, n=1561and Peripheral vascular diseases rank, n=14088. All participants finished baPWV examination. The relationship between TG and baPWV was studied by partial correlation analysis, the impact of TG on baPWV was assessed by multivariate linear regression and multivariate Logistic regression analysis. Results: There were 21713 subjects finally enrolled for cohort study and 909 subjects excluded for missing TG information. With elevated TG levels, the average baPWV and the detection rate of baPWV≥1400 cm/s showed the increasing trend. Partial correlation analysis presented that TG level was positively related to baPWV, r=0.235; with adjusted age and gender, TG was still positively related to baPWV, r=0.080. Logistic regression analysis indicated that with other adjusted confounding factors, compared with the first quartile of TG, the second quartile, third quartile and fourth quartile of TG were the risk factors for baPWV≥1400 cm/s, OR=1.161, 95% CI (1.035-1.302), OR=1.312, 95% (1.165-1.476) and OR=1.652, 95% CI (1.463-1.865) respectively. Conclusion: Blood TG level was positively and independently related to baPWV in relevant population.
