ABSTRACT
Objective:To explore the prognosis of epithelial ovarian cancer patients with multiple recurrences (≥2 times) who underwent three times or more cytoreductive surgeries, and to analyze the factors associated with prognosis.Methods:The clinicopathological data and follow-up data of 23 patients with ovarian cancer admitted to the Obstetrics and Gynecology Hospital of Fudan University from January 1, 2015 to January 30, 2022 with three times or more cytoreductive surgeries were collected. The degree of surgical resection, site of recurrence and metastasis, postoperative complications, and prognosis were retrospectively analyzed. The univariate Cox proportional hazards model was performed to identify the variables associated with survival.Results:(1) The median age of 23 patients with multiple recurrent ovarian cancer was 48 years old (44-55 years). Among them, 18 cases underwent tertiary cytoreductive surgery (TCS), 2 cases underwent quaternary cytoreductive surgery, 2 cases underwent quinary cytoreductive surgery, and 1 case underwent senary cytoreductive surgery. Among the 23 patients with multiple recurrent ovarian cancer, 21 cases (91%, 21/23) had serous carcinoma, 16 cases (70%, 16/23) had advanced stage (stage Ⅲ-Ⅳ), and 19 cases (83%, 19/23) had high differentiation. (2) Based on the premise that satisfactory cytoreduction was achieved by primary debulking surgery (PDS) and no visible residual disease (R0) was achieved by secondary cytoreductive surgery (SCS), the maximum diameter of the recurrent tumors was up to 10.0 cm and 62% (20/32) of patients with multiple metastatic sites. The R0 rate for three times or more cytoreductive surgeries (32 times in total) reached 88% (28/32), with a postoperative complication rate of 47% (15/32), and only 3% (1/32) for grade Ⅲ or above. During a median follow-up time of 31.1 months (20.6-43.9 months) after TCS, 20 patients (87%, 20/23) recurred after TCS, and 8 patients (35%, 8/23) eventually died of ovarian cancer. Among them, the three-year postoperative survival rate of 22 patients with R0 was 57.6%, and the patient with residual lesions ≥1 cm died at 9.2 months after TCS. (3) In univariate analysis, ages, the time interval between PDS and SCS >32 months, the interval between SCS and TCS >16 months, and no metastatic peritoneal carcinoma were associated with longer progression free survival after TCS (all P<0.05); while treatment-free interval (TFI) >10 months after SCS, the interval between SCS and TCS >16 months, no ascites and platinum-sensitive status were associated with disease-specific survival after TCS (all P<0.05). Conclusions:It is feasible to perform three times or more cytoreductive surgeries in patients with multiple recurrent ovarian cancer who are expected to achieve R0 and have manageable complications. However, the pros and cons of surgery need to be carefully evaluated for the patients whose ascites are massive and whose previous cytoreduction does not achieve R0. A prolonged TFI and previously longer surgical interval might get potential survival benefits.
ABSTRACT
ObjectiveTo analyze the induction effect of Fusobacterium nucleatum （Fn） on endoplasmic reticulum stress-related proteins Glucose-regulating protein 78（GRP78） and X-box binding protein 1（XBP1） in esophageal squamous cell carcinoma （ESCC）， and to explore its potential mechanism and clinical significance. MethodsESCC cells KYSE150 and KYSE140 were infected with Fn for 12 h， 24 h and 48 h. The oxidative stress indexes （ROS， MDA and SOD） and the expression of GRP78 and XBP1 in each group were detected by oxidative stress index kit and Western blot. The experiment was divided into Fn groups， Fn+siNC1 groups， Fn+siGRP78 groups， Fn+siNC2 groups and Fn+siXBP1 groups； the oxidative stress indexes， paclitaxel （PTX） response efficacy， abilities of proliferation， invasion and metastasis in each group were compared. The infection of Fn and the expression of GRP78 and XBP1 in 234 ESCC and paracancerous tissues were detected by RNA scope and immunohistochemistry. The correlation between each factor and clinicopathological characteristics of patients was analyzed by Chi-square test. The influence of each factor on the survival of patients was compared by Kaplan-meier survival estimate. ResultsCompared with Fn uninfected KYSE150 and KYSE140 cells， the content of ROS and MDA was gradually increased， the activity of SOD was gradually decreased， and the expression of GRP78 and XBP1 was gradually increased in Fn infected groups （12 h， 24 h and 48 h） （P < 0.05）. Compared with Fn groups， Fn+siNC1 groups， and Fn+siNC2 groups， ROS and MDA contents were decreased， SOD activity was increased， PTX response efficacy was enhanced， and abilities of proliferation， invasion and metastasis were decreased in Fn+siGRP78 and Fn+siXBP1 groups （P < 0.05）. The rates of Fn， GRP78 and XBP1 in ESCC tissues were 43.16%， 69.66% and 60.68%， respectively. And the three indexes were significantly consistent （P < 0.05）. The patients with positive Fn infection and high expression of GRP78 and XBP1 were mostly males with a history of smoking and drinking， and the tumor differentiation degree was low， the invasion degree was deep， the lymph node metastasis rate was high， and the clinical stage was mostly stage Ⅲ/Ⅳ. The 5-year survival time of patients with above positive indexes was shortened （P < 0.05）. ConclusionsFn could induce endoplasmic reticulum stress by inducing the high expression of GRP78 and XBP1， and promote the malignant evolution of ESCC.
ABSTRACT
Two male patients with bifid rib-basal cell nevus-jaw cyst syndrome (BCNS) were admitted to Department of Stomatology, the First Affiliated Hospital of Bengbu Medical College due to radiological findings of multiple low density shadows in the jaw. Clinical and imaging findings showed thoracic malformation, calcification of the tentorium cerebellum and falx cerebrum as well as widening of the orbital distance. Whole exon high-throughput sequencing was performed in two patients and their family members. The heterozygous mutations of c.C2541C>A(p.Y847X) and c.C1501C>T(p.Q501X) in PTCH1 gene were detected in both patients. Diagnosis of BCNS was confirmed. The heterozygous mutations of PTCH1 gene locus were also found in the mothers of the two probands. Proband 1 showed clinical manifestations of low intelligence, and heterozygous mutations of c.C2141T(p.P714L) and c.G3343A(p.V1115I) were detected in FANCD2 gene. Proband 2 had normal intelligence and no FANCD2 mutation. The fenestration decompression and curettage of jaw cyst were performed in both patients. Regular follow-up showed good bone growth at the original lesion, and no recurrence has been observed so far.

Objective:To investigate the clinical effect of spousal kidney transplantation , and to explore the significance in today's society.Methods:We retrospectively collected the relevant clinical data from the transplantation department of the first hospital of jilin university, from October 2009 to December 2018. Receptors who accepted spousal, parental and compatriot donor kidney is respectively obtained.Then the postoperative efficacy of the three groups were compared.Results:The graft survival rates of spousal kidney transplantation were 94.1% at 3 years and 83.7% at 5 years, which were not significantly different from other types of living kidney transplantation ( P=0.260). There was no significant difference in creatinine at each time point within 3 years after operation between three groups. At 3 years and 5 years after operation, there was no significant difference in creatinine between spouse group and sibling group.But the creatinine of spouse group was lower compared with parent group ( P=0.014, 0.038). The incidence of rejection within 1 years after spousal renal transplantation was 25%, which was significantly higher than parent group and sibling group ( P=0.029). Age of donor, gender of recipient, D/R BMI and incidence of AR or not in recipient were independent predictors for 1-year creatinine in living kidney transplantation (correlation coefficient: 0.048、-26.03、-15.95、10.23; P=0.003、<0.001、0.021、0.013). Conclusions:Spousal kidney transplantation has same clinical efficacy compared with other types of living kidney transplantation, which can greatly improve the donor kidney resource.So it worth being further promotion, but compared with other types of living kidney transplantation, we should be more alert to the incidence of rejection reaction, so as to obtain better curative effect.
ABSTRACT
Diabetic cardiomyopathy occurs in diabetic patients and is different from hypertensive heart disease， coronary atherosclerotic heart disease， and other cardiac abnormalities. The main clinical symptoms are systolic and diastolic cardiac dysfunction， myocardial fibrosis， congestive heart failure， and angina pectoris. As one of the main complications of diabetes， its incidence and fatality rates have been on the rise year by year. However， modern medicine still fails to figure out its pathogenesis and no specific drug is available， which has seriously affected the survival and quality of life of patients. Cardiomyocytes contain a large number of mitochondria， which participate in cardiac energy metabolism and other biological activities and occupy an important position in the development of diabetic cardiomyopathy. Mitochondrial quality control mainly involves mitochondrial oxidative stress， mitochondrial dynamics， mitochondrial autophagy， and intracellular calcium regulation， which is an important condition for stabilizing the normal mitochondrial structure and exerting normal mitochondrial functions. In recent years， the efficacy of traditional Chinese medicine in intervening in mitochondrial quality control through multiple angles， pathways， and targets to affect the structure and function of myocardial mitochondria and significantly improve the clinical symptoms of patients with diabetic cardiomyopathy has attracted wide attention from scholars. Therefore， this paper reviewed the experimental studies and/or clinical observations concerning the treatment of diabetic cardiomyopathy with effective compounds of Chinese herbs and/or Chinese herbal compounds in the past ten years to further explain the pathogenesis of diabetic cardiomyopathy， clarify the regulatory mechanism of traditional Chinese medicine in mitochondrial quality control， and summarize the scientific connotations and shortcomings of traditional Chinese medicine in the treatment of diabetic cardiomyopathy， hoping to provide certain ideas and methods for further clinical application of traditional Chinese medicine in the treatment of diabetic cardiomyopathy.
ABSTRACT
Objective:To investigate the clinical efficacy of psychotherapy combined with auricular plaster therapy in the auxiliary treatment of insomnia caused by liver fire disturbance in a sub-healthy population.Methods:Eighty sub-healthy patients with insomnia caused by liver fire disturbance who received treatment in Wenzhou Hospital of Traditional Chinese Medicine from June 1, 2017 to December 31, 2018 were included in this study. These patients were randomly assigned to receive cognitive behavioral therapy (control group, n = 40) or cognitive behavioral therapy combined with auricular plaster therapy (observation group, n = 40) for 4 weeks. Polysomnography was used to evaluate the sleep condition before and after treatment. The Pittsburgh Sleep Quality Index was used to evaluate the severity of insomnia. The World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF) was used to evaluate the quality of life of patients. The therapeutic effect was compared between the two groups. Results:After treatment, total sleep time [(421.25 ± 11.58) min vs. (456.25 ± 11.23) min], sleep efficiency [(70.32 ± 4.44)% vs. (76.58 ± 5.89)%], non-rapid eye movement stage 2 (N2) sleep [(43.25 ± 4.44)% vs.(45.62 ± 4.36)%], N3 sleep [(14.25 ± 4.52)% vs. (18.52 ± 5.55)%], rapid eye movement (R) sleep [(21.98 ± 5.21)% vs. (24.66 ± 4.87)%] in the control group were significantly shorter or lower than those in the observation group ( t = 13.723, 5.367, 9.035, 2.408, 3.772, 2.376, all P < 0.05). After treatment, sleep quality [(1.85 ± 0.54) points vs. (1.10 ± 0.42) points], sleep-onset latency [(1.52 ± 0.51) min vs. (1.08 ± 0.35) min], sleep duration [(1.30 ± 0.41) min vs. (0.75 ± 0.41) min], sleep efficiency [(1.53 ± 0.44) points vs. (1.02 ± 0.33) points], sleep disturbance [(1.20 ± 0.41) points vs. (0.78 ± 0.31) points], hypnotics [ (0.11 ± 0.02) points vs. (0.04 ± 0.01) points], daytime dysfunction [(1.65 ± 0.47) points vs. (1.03 ± 0.28) points] and total scores [(9.11 ± 1.33) points vs. (5.80 ± 1.01) points] in the control group were significantly higher than those in the observation group ( t = 6.933, 4.499, 5.999, 5.864, 5.167, 19.789, 7.167, 12 535, P < 0.05). After treatment, the scores in physical health [(13.85 ± 2.22) points vs. (17.86 ± 2.01) points], psychological domain [(15.52 ± 1.89) points vs. (16.35 ± 1.33) points], social relationships [(16.01 ± 1.58) points vs. (19.52 ± 1.85) points] and environment domain [(17.52 ± 1.90) points vs. (20.89 ± 2.22) points] in the control group were significantly lower than those in the observation group ( t = 8.468, 4.499, 9.124 and 7.294, all P < 0.05). After treatment, total effective rate in the observation group was significantly higher than that in the control group [95.0% (38/40) vs. 72.5% (29/40), χ 2 = 7.440, P < 0.05]. Conclusion:Psychotherapy combined with auricular plaster therapy can significantly increase the sleep duration and sleep efficiency and improve the quality of life of sub-healthy patients with insomnia caused by liver fire disturbance, which is worthy of clinical promotion.
ABSTRACT
OBJECTIVE@#To investigate the prevalence rate of hypothyroidism in children with β-thalassemia major (β-TM) and its risk factors.@*METHODS@#A total of 86 children with β-TM treated and followed up in the Department of Pediatrics of the Fifth Affiliated Hospital of Sun Yat-Sen University, Zhuhai Municipal Maternal and Child Health Care Hospital from August 2018 to August 2020 were enrolled. The clinical data of the children were analyzed to investigate the prevalence rate of hypothyroidism in children with β-thalassemia major (β-TM) and its risk factors.@*RESULTS@#The prevalence rate of hypothyroidism in children with β-TM in Zhuhai area was 17.4%. The level of serum ferritin(SF) (4948.27±1225.33 μg/L) in hypothyroidism children was significantly increased(t=10.273，P<0.05). The prevalence rate of hypothyroidism was significantly higher in β-TM children(age ≥10 years old, SF ≥2 500 μg/L and irregular iron removal) (P<0.05). Logistic regression result showed that age ≥10 years old was the independent risk factor affecting the increasing of hypothyroidism rate in the children. The levels of SF(3880.60±1269.17 μg/L), TSH(4.43±1.52 mIU/L) and the prevalence rate of hypothyroidism(37.14%)(P<0.05) were higher for the children in irregular iron removal group.@*CONCLUSION@#The prevalence rate of hypothyroidism in children with β-TM in Zhuhai area is high, and it is related to the age ≥10 years old, SF ≥2 500 μg/L and irregular iron removal of the children.

Besides the advantages of high sensitivity, non-invasive, and real-time imaging that the general optical imaging technologies have, the second near-infrared (1 000-1 700 nm) in vivo imaging is regarded as one of the most promising optical imaging technologies in clinical applica-tion at present due to its advantages such as low autofluorescence background, deep tissue penetration and clear imaging. In the second near-infrared imaging system, the fluorescence probe is the most critical technical difficulty and the current research hotspot. Thereinto, due to the unique physical and chemical properties of nanomaterials, the second near-infrared fluorescent nanoprobe is an ideal contrast agent for the current second near-infrared optical imaging technology. The reported inorganic materials that can be used as the second near-infrared fluores-cent nanoprobes include quantum dots, rare earth nanoparticles, and single-walled carbon nanotubes, and the reported organic materials are mainly conjugated polymers. In this paper, the research progresses of the second near-infrared fluorescence nanoprobes mentioned above are re-viewed in order to better understand their application to the field of biomedicine, and promote the further research and clinical application of the second near-infrared in vivo imaging to the biomedical field.
ABSTRACT
OBJECTIVE@#To evaluate the effect of using free double- leaf perforator flap posterolateral calf peroneal artery in anatomical reconstruction of the oropharyngeal structure after ablation of advanced oropharyngeal carcinoma.@*METHODS@#Twenty-six patients with oropharyngeal defects after ablation of oropharyngeal malignancies were recruited, including 12 with carcinoma in the tongue base, 5 in the latenral pharyngeal wall and 9 in the soft palate. Between July, 2016 and July, 2018, the patients underwent surgeries for reconstruction of the oropharyngeal defects using flaps. The areas of tissue defects repaired by double-leaf perforator flaps ranged from 40.5 to 72.5 cm. Reconstruction was performed for oropharyngeal defects in the soft palate, pterygopalate, parapharyngeal, pterygo- mandibular, and tongue base tissues. The patients' outcomes including mouth opening, functions of deglutition, linguistic function, restoration of palatopharyngeal anatomical structure and postoperative survival were evaluated, and their quality of life was assessed using FACT-H&N scale (Chinese Edition).@*RESULTS@#All the 26 patients with transplantation of the free flaps survived. Six months after the operation, the oropharyngeal function and anatomical structure of the patients were basically restored. The questionnaire survey showed that the patients' physical, social/family, emotional and functional conditions, the total score of the core scale, items scores for the head and neck, and the total score of the scale all improved significantly after the operation compared with those before the operation ( < 0.05).@*CONCLUSIONS@#The free peroneal artery bilobate perforator flap in the posterolateral crus, which seldom has anatomical variations of the blood vessels, allows flexible design and contains rich tissue volume to facilitate defect repair with different approaches and ranges. The application of this flap, which is an ideal perforator flap for reconstruction of the oropharyngeal structure and function, can improve the quality of life of patients following operations for advanced oropharyngeal cancer.

Objective To evaluate the effect of double-leaf perforator free flap pedicled with posterolateral calf peroneal artery on repairing facial through-and-through defect after oral cancer oblation.Methods Nine patients with facial through-and-through defects after oblation of oral and maxillofacial malignancies,including 4 cases of buccal mucosa carcinoma,2 cases of maxilla osteosarcoma,1 case of carcinoma of the maxillary sinus and 2 cases of parotid duct carcinoma,were recruited from May,2016 to May,2018.The flap was used to repair the facial defect of recruited patients.The area of the bigger leaf of bilobed perforator flap was 7.0 cm×8.0 cm-6.0 cm×7.0 cm and the small leaf was 4.5 cm×4.5 cm-4.0 cm×4.0 cm,respectively.The intraoral and facial defects needed to be reconstructed contained the oral mucosal of the upper palate,the skin,subcutaneous tissue and mucosa of the cheek.The radiotherapy was performed 1.0-1.5 months after the operation.The prognosis including appearance,mouth opening,and the functions of deglutition,and language were assessed.Results Through 3-18 months outpatient followed-up,all 9 cases of transplanted flaps survived well and the incisions of the donor and recipient areas healed by first intention.The patients were satisfied with the facial appearance,mouth opening,and the functions of deglutition and language at the 6 months follow-up.The radiotherapy had no damage on the survival of the bilobed perforator flap.There was no recurrence or metastasis in follow-up.Conclusion The double-leaf perforator free flap pedicled with posterolateral calf peroneal artery is an ideal free tissue for repairing the facial perforating defect after oral cancer oblation because of its constant blood vessel,abundant tissues,flexible design and operating methods.
ABSTRACT
To evaluate the clinical effect of application of free peroneal artery perforator flap in repairing postoperative tissue defect after resection of oral maxillary malignant tumor. Methods From January, 2016 to June, 2018, 14 patients with maxillary malignant tumor were treated with tumor excision. Then the free per-oneal artery perforator flap was used to reconstruct tissue defect caused by tumorectomy. There were 6 cases of squa-mous-cell carcinoma of palatine, 2 cases of adenoid cystic carcinoma of palatine, and 6 cases of maxillagingiva squa-mous cell carcinoma. The incised area of flap was 4.0 cm×5.0 cm to 7.0 cm×8.0 cm. There were 5 cases of hard palate soft tissue defect repair and 9 cases of simultaneous repair of soft and hard palate. Followed-up by outpatient service in 3-12 months after operation, postoperative maxillamorphology, phonetic function, swallow function, opening degree and prognosis of the patients were evaluated. Results All 14 implanted flaps were alive.One flap had vas-cular crisis, and rescued by surgical exploration and timely rescue.Three flaps were prolonged healing.All donor sites were sutured directly.All surgical incisions healed primarily.Half a year after the operation, the appearance of maxilla was formed gradually. The phonetic function, swallowing function, opening degree and movement of lower leg were all recovered normal. One year after the operation, epithelization was done in 6 cases. And there was no tumor recur-rence.Conclusion The peroneal artery perforator flap has long vascular pedicle, larg diameter, high survival rate after vascular anastomosis and relatively concealed donor area. It can be used to repair and reconstruct the tissue defect in maxillary malignant tumor resection and achieved good result.
ABSTRACT
Objective: To analyze the current non-linear and spatial dependence of health industry clustering and residents' health level in China. Methods: Using the panel data of China from 2002 t0 2017, the panel threshold model and the spatial Dubin model were constructed to conduct empirical tests. Results and Conclusion: Based on the internal perspective of the region, it was found that whether the health industry cluster would inevitably promote the improvement of residents' health level was bound by the threshold of agglomeration scale. Only when the agglomeration scale was in the median interval of [1.209, 1.763], the output effectiveness of the health industry cluster was more significant; based on the spatial spillover perspective, the positive health "spill effect" caused by the accumulation of health and health industries in the surrounding areas had made compensation on the “health short board” of the health and health industry in the region although the health and industrial clusters in the region had not made significant contributions to the improvement of the health of local residents.
ABSTRACT
Thyroid nodule is a very common disease, and most of the diseases are asymptomatic with benign ultrasound or cytology,which do not require treatment. A regular observation is commonly required, and its frequency should be determined based on the potential risk of malignancy. Only a few benign nodules need intervention due to some certain factors including neck discomfort,cosmetic problem and patients' desire. The nonsurgical treatments include thyroxine suppression therapy, percutaneous ethanol injection, thermal ablation, and radioactive iodine therapy, etc. Currently, active surveillance and thermal ablation are still an experimental treatment in debate for low-risk thyroid cancer. In a patient-centered approach, clinicians should assess the indications,benefits, and risks of various nonsurgical treatments in order to avoid over-treatment.
ABSTRACT
Plant type Ⅲ polyketide synthases (PKSs), the pivotal enzymes in the biosynthesis of polyketides, produce backbones of many structurally diverse and functionally different polyketides. So far, a variety of functionally diverse plant type Ⅲ PKSs have been cloned and identified from plant origin. Site-directed mutagenesis is a useful technique to study the complex relationship between protein structure and function. This review summarized advances in the structure-function relation of plant type Ⅲ polyketide synthases by site-directed mutagenesis in recent years, including the modification of the amino acid residues influencing enzyme architectures (such as controlling the specificity of starter substrates, the number of condensation reactions, and the cyclization reactions of the intermediate product). This review provides information to study the structure-function relation of plant type Ⅲ polyketide synthases.
ABSTRACT
Objective To explore the dosimetric characteristics of single photon emission computed tomography(SPECT)combined with bone marrow sparing intensity modulated radiotherapy in patients with cervical cancer.Methods Twenty patients with cervical cancer after hysterectomy were performed on 99Tc thiocolloid SPECT bone marrow imaging to determine the active bone marrow in the pelvis.SPECT image combined with the simulation CT was used as the primary planning data set.Two plans for bone marrow sparing modulated radiotherapy were generated according to the bone marrow volume defined by SPECT and outline of the pelvis(SPECT-IMRT planning and BMS-IMRT planning).Furthermore,the target section and the dosimetric distribution in organs at risk(bone marrow,small intestine,rectum and bladder)in the two plannings were compared.The prescribed dose to the PTV was 45 Gy.Results The volume of the bone marrow in SPECT-IMRT planning and BMS-IMRT planning was(238.15 ±36.82)and(1 100.61 ±109.92)cm3,respectively(t＝33.273,P＜0.05).The average bone marrow volume of SPECT-IMRT planning in high-dose radiation region(V30,V40and V45)was decreased by 6.9％,5.7％and 2.6％respectively compared with BMS-IMRT planning(t ＝3.540,3.4261,3.448,P＜0.05),but there was no statistical significant difference between the two plannings in the dose volume of low-dose radiation(V10and V20,P＞0.05).The PTV coverage rate and exposure dose of other organs at risk(small intestine,rectum and bladder)in the two plannings were not significantly different(P＞0.05).Conclusions SPECT bone marrow imaging could clearly show the range of active bone marrow on CT scan images.Compared with BMS-IMRT,SPECT-IMRT could further reduce the dose volume of high-dose radiation(V30,V40and V45).Yet the clinical significance of this advantage also needs to be confirmed by large-scale clinical studies.

IL-10 mainly plays biological functions via JAK-STAT signaling pathway. IL-10 is a crucial anti-inflammation cytokine taking part in immune regulation and having significant effect on autoimmune diseases. This paper reviews the relationships be-tween IL-10 and autoimmune diseases according to research achievements in recent years.
ABSTRACT
Objective To assess the value of outflow angle-assisted (OA-assisted) approach in diagnosing and differentiating sidewall cerebral aneurysms (SCAs) with magnetic resonance angiography (MRA). Methods A total of 438 patients with suspected SCAs and other cerebrovascular diseases were separately evaluated by OA-assisted approach MRA and digital subtraction angiography (DSA). An OA of ≥90o was considered to represent SCA. The diagnostic accuracy, sensitivity, and specificity of SCAs with OA assisted approach were evaluated with the number of aneurysms and the size of aneurysms. Results DSA revealed 301 SCAs in 267 patients, and no SCAs was detected in the remaining 171 patients, among them a total of 55 infundibulae were observed in 52 patients. OA-assisted approach MRA revealed 300 SCAs in 267 patients, among which 271 aneurysms in 238 patients had an OA of ≥90o(true positive of 90.3％) and 29 aneurysms in 29 patients had an OA of <90° (false negative of 9.7％). Based on the patient, the number of aneurysms and the size of aneurysms, OA-assisted approach MRA had higher accuracy, sensitivity and specificity in diagnosing SCAs. The OA of all 54 infundibulae observed in 51 patients was <90°(98.2％), and only one infundibula in one patient was ≥90° (false positive). Conclusion MRA with OA-assisted approach has higher accuracy in diagnosing SCAs and in differentiating SCAs with infundibula, therefore, it can substitute DSA for the diagnosis and differentiation of SCAs.
ABSTRACT
Objective: To investigate the effect of macrophage-capping protein (CapG) on migration and proliferation of human gastric cancer cell line.Methods: Real-time PCR method was used to detect the expression of CapG gene in four gastric cancer cell lines, and AGS cells with low expression and transfection were selected as the research objects.Specific primers were designed for CapG and recombinant plasmids synthesized.A lentivirus packaging system which could express CapG was constructed, and a cell line stably expressing CapG was established by infecting human gastric cancer cell line AGS cells.The effect of overexpression of CapG gene on the growth and proliferation of AGS cells was analyzed by CCK8 assay.Cells cratch and Transwell assay were used to analyze the effect of overexpression of CapG gene on AGS cell migration.Results: After the overexpression of CapG, the growth rate of AGS cells was slightly lower than that of the control group, but there was no significant difference between the two groups (t=2.424, P=0.073).Scratch test showed that the average narrowing distance of the scratches in the CapG experimental group was significantly reduced compared with the control group, the average narrowing distance of the CapG experimental group and the control group was 336.99 μm and 45.54 μm, the difference was statistically significant (t=14.97, P=0.004).The average number of cell penetra-ting membrane in the CapG experimental group and the eGFP control group was 176 and 70, the number of the cells in the CapG experimental group was significantly higher than that of the control group (t=40.00, P<0.001).Conclusion: The overexpression of CapG gene has no significant effect on the growth and proliferation of AGS cells of gastric cancer cell line.Overexpression of CapG gene can promote the migration of AGS cells of gastric cancer cell lines.
ABSTRACT
Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in China and manifests as simple fatty liver, non-alcoholic steatohepatitis, liver cirrhosis, and hepatocellular carcinoma. Studies have shown that intestinal flora can affect the development and progression of NAFLD via the "gut-liver axis" . Probiotics are active microorganisms with beneficial effects on the host, and more and more studies have found that probiotics play a positive role in improving NAFLD. They are cheaper, less harmful, and safer compared with antibiotics and surgery, and therefore, it may become a new method for the prevention and treatment of NAFLD. This article reviews the research advances in probiotics in the treatment of NAFLD, in order to provide a basis for the treatment of NAFLD using probiotics.

Objective:To explore influence of preoperative intensive atorvastatin therapy on no-reflow and cardiac function after selective percutaneous coronary intervention (PCI).Methods:A total of 96 selective PCI patients treated in our hospital from Feb 2015 to Feb 2016 were selected.According to complete random grouping method, patients were randomly and equally divided into normal dose group (received atorvastatin of normal dose)and inten-sive group (received intensive atorvastatin therapy).Corrected TIMI frame count (CTFC),left ventricular ejection fraction (LVEF),left ventricular end-systolic volume index (LVESVI),left ventricular end-diastolic volume index (LVEDVI)before and one month after PCI,incidence rate of no-reflow were observed and compared between two groups.Results:Compared with normal dose group on one month after PCI,there were significant reductions in CTFCs of right coronary artery [(36.96±5.48)vs.(29.87±6.03)],left anterior descending artery [(37.57± 6.31)vs.(30.25±5.74)],left circumflex artery [(37.01±6.04)vs.(26.52±5.73)],mean CTFC [(37.03± 6.21)vs.(29.24±6.02)],incidence rate of no-reflow (16.67% vs.4.17%),LVESVI [(37.23±10.49)ml/m2 vs.(30.46±11.53)ml/m2 ]and LVEDVI [(80.02±14.38)ml/m2 vs.(71.34±16.52)ml/m2 ],and significant rise in LVEF [(43.11±5.23)% vs.(47.37±7.57)%]in intensive group,P <0.05 or <0.01. Conclusion:Preop-erative intensive atorvastatin therapy can effectively reduce incidence rate of no reflow and improve cardiac function of patients after PCI,which is worth extending.
