Objective To observe the effect of Ginkgo Biloba Extract Injection on urinary albumin excretion rate in patients with diabetic nephropathy (DN). Methods A total of 90 patients with DN were divided into two groups: group A was micro-urinary-albumin group; group B was multiple-urinary-albumin group. Both groups were treated with routine therapy plus Ginkgo biloba extract injection (at a dose of 15ml) q.d. for 4 consecutive weeks. The urinary albumin excretion rate was compared between the two groups before and after treatment. Results As compared with the group B, urinary albumin excretion rate was significantly lowered in the group A (P＜0.01). Conclusion Ginkgo Biloba Extract Injection had effects in lowering microalbumin in urine and therapeutic effect for patients with early DN.

Purpose To investigate the adverse reactions and management in the process of transvaginal real-time three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy).Materials and Methods A total of 976 patients with infertility accepting 3D-HyCoSy in Jiangsu Provincial Hospital of Traditional Chinese Medicine,Affiliated Hospital of Nanjing University of Traditional Chinese Medicine,from December 2014 to August 2016 were retrospectively analyzed.The pain degree was evaluated using visual analog scale (VAS).Adverse reactions,including contrast countercurrent,vomiting,syncope and allergies,were recorded.The relationship between adverse reactions and ultrasound imaging signs was explored.Results There were 66 cases (6.76％) of VAS grade 0,346 cases of mild pain (35.45％),374 cases of moderate pain (38.32％) and 190 cases (19.47％) of severe pain.With the increase in the degree of tubal obstruction,the degree of pain gradually increased.Pain was the most common adverse reaction among patients,followed by vomiting (15 cases,1.54％),syncope (1 case,0.10％),and allergies (1 case,0.10％).The incidence of contrast countercurrent was 12.30％ (120 cases).The adverse reaction incidence of patients with abnormal ultrasound imaging signs was significantly higher than that of patients with normal signs (x2=29.02,P＜0.01).Conclusion With the extensive use of 3D-HyCoSy examination,its clinical application value has attracted a lot of attention,meanwhile,the understanding of its safety and related adverse reactions should also be improved.The state of patients should be closely observed before,during and after 3D-HyCoSy.Medical personnel should watch out for syncope and allergic reactions,and prepare for emergency management.

Aim To investigate the expression of Notch pathway and Nephrin in angiotensin Ⅱ ( AngⅡ)-stimulated mice podocyte. Methods Mice podo-cyte was stimulated by AngⅡ, and then was treated with valsartan. The levels of Notch1, Notch intracellu-lar domain 1 ( NICD1 ) , Hes1 and Nephrin were deter-mined by immunofluorescence, Western blot and Real-time PCR. Results AngⅡincreased Notch1, NICD1 and Hes1 expression, and decreased Nephrin expres-sion in a time-dependent manner ( P<0. 01 ) . Valsar-tan inhibited AngⅡ-induced activation of Notch path-way and enhanced Nephrin level ( P <0. 01 ) . Con-clusion AngⅡdecreases Nephrin expression in podo-cyte by activating Notch pathway.

Purpose To investigate the role of SOCS3 on diabetic renal injury. Methods Male CD-1 mice were randomly divided into four groups:control group, diabetic group, empty plasmid vector transfection group and SOCS3 plasmid transfection group. The diabet-ic mice were induced by intraperitoneal injection of STZ at a dose of 150 mg/kg body weight. The mice of transfection group were re-ceived an injection of SOCS3 plasmid or empty vector at every 7 days thereafter. Specimens were collected at 12 week after STZ injec-tion. The morphological changes of tubular epithelial cells were observed by transmission electron microscope. RT-PCR and immuno-histochemistry were used to determine the mRNA and protein expression of CK18 and α-SMA. Western blotting analysis was used to determine the protein expression of SOCS3, p-STAT3, CK18 and α-SMA. Results SOCS3 overexpression in kidney down-regulated the levels of p-STAT3 andα-SMA but up-regulated the expression of CK18. Conclusion Overexpression of SOCS3 can ameliorate the tubular epithelial-mesenchymal transdifferentiation of diabetic mice via inhibiting the phosphorylation of STAT3.

Objective To evaluated intra-articular injection of TNF-α inhibitors into the sacroiliac joint as an effective and viable alternative. Methods Sixteen patients with documented ankylosing spondylitis (AS), without steroids or disease modifying anti-rheumatic drugs (DMARDs) were performed CT-guided intra-articular injections of etanercept (TNF-α antagonist) at week 0, 4 and 8 (25 mg per dose). Similarly, 20 patients with AS in the control group received systemic etanercept therapy at a dose of 50 mg per week for 8 weeks. All patients were followed up clinically and evaluated periodically. Pathological features of sacroiliitis were observed with light microscopy and immunohistochemistry. Expression of cytokines in joint biopsy samples was estimated by RT-PCR. Image changes of sacroiliitis were observed by SPECT/CT and MRI. Ttest, t'tesr and χ2 Fisher's test were selected. Results All the 16 patients who received intra-articular etanercept, the mean value of radiological nuclide decrease of the SIJ ROI (region of interest) in the SPECT improved significantly after 8 weeks treatment [(1.38±0.16 vs 1.45±0.14) P<0.05] . Bone marrow edema and fat deposition in MRI were relieved significantly after 8 weeks (P<0.05). In 8 patients the expression of TNF-α and TGF-β mRNA in joint tissue decreased significantly after 8 weeks [(0.89±0.06, 0.84±0.05) vs (l.08± 0.19, 1.13±0.33) (P<0.05)]. The occurrence of gynonitis, enthesitis, chondritis, subehondral bony plate destruction, bone marrow inflammation and inflammatory cell index also decreased significantly (P<0.05). Participants given intra-articular injection showed significant clinical improvement after 8 weeks and 12 weeks treatment(P<0.01 ) in BASDAI score [(32±13) mm]. Conclusion This study has shown that intra-articular injection of etanercept in SIJ can improve joint function and quality of life. It has a satisfactory safety profile and is cost effective. This mode of treatment is most beneficial in local arthropathy of recent onset and in those patients who do not tolerate systemic etanercept therapy.

OBJECTIVETo investigate the role of apoptosis in radiation-induced mouse thymus lymphocyte damage and repair and provide the basis for understanding the molecular mechanism of radiation-induced lymphocyte damage and repair as well as the prevention and treatment of acute radiation sickness.

METHODSWe studied the dynamic changes of apoptosis of mouse thymus lymphocytes and the expression of bax and bcl-2 gene products after 2, 4, 6 and 8 Gy of whole body gamma-irradiation using in situ terminal labeling, DNA electrophoresis and immunohistochemical techniques.

RESULTSAt the early stage after irradiation, the percentage of apoptotic lymphocytes increased rapidly in accordance with the increasing of radiation doses, while the counts of the thymus and peripheral lymphocytes decreased sharply, showing an opposite change to lymphocyte apoptosis. After 6 Gy gamma-irradiation, typical morphological characteristics of thymus apoptotic lymphocytes in early, middle and late stages were found by transmission electron microscopy. The thymus lymphocytes displayed characteristic DNA ladders 4 hr and 8 hr after 2-6 Gy gamma-irradiation,using DNA gel electrophoresis techniques. Abnormal expression of bcl-2 and bax gene products were shown in irradiated lymphocytes.

CONCLUSIONSApoptosis plays an important role in the process of radiation-induced mouse thymus lymphocyte damage and repair. Bcl-2 and Bax proteins may regulate the process of lymphocyte apoptosis.

Objective:To investigate the expressions and significances of autophagy-related genes Beclin-1, LC3 and p62 in esophageal squamous cell carcinoma (ESCC).Methods:The clinical data of 112 patients with primary ESCC who underwent surgery at the 81st Group Army Hospital of Chinese PLA from January 2015 to December 2016 were retrospectively analyzed. Immunohistochemistry was used to examine the expressions of Beclin-1, p62 and LC3 proteins in 112 ESCC tissues and 31 adjacent normal esophageal mucosa tissues. Furthermore, the expressions of the above three autophagy-related markers in ESCC and the relationship between their expressions and the clinicopathological characteristics of patients were analyzed.Results:The positive expression rates of Beclin-1, LC3 and p62 in ESCC tissues were 32.14% (36/112), 37.50% (42/112) and 63.39% (71/112), The positive expression rates of Beclin-1, LC3 and p62 in adjacent normal esophageal mucosa tissues were 61.29% (19/31), 64.52% (20/31) and 32.26% (10/31), and the differences were statistically significant ( χ2 values ??were 8.715, 7.216 and 9.584, all P < 0.01). The positive expression rates of Beclin-1 and LC3 in ESCC were lower than those in adjacent normal esophageal mucosa tissues, and the positive expression rate of p62 in ESCC was higher than that in adjacentnormal esophageal mucosa tissues. In ESCC patients, the expression of Beclin-1 was related to histological grade, infiltration depth, TNM staging and lymph node metastasis (all P < 0.05); the expression of LC3 was related to infiltration depth and TNM staging (both P < 0.01); the expression of p62 was related to lymph node metastasis ( P < 0.01). In ESCC, the expression of LC3 was positively correlated with the expression of Beclin-1 ( r = 0.731, P = 0.001), and negatively correlated with the expression of p62 ( r = -0.215, P = 0.023). Conclusions:Autophagy plays a certain role in the occurrence and development of ESCC. Combined detection of autophagy-related genes Beclin-1, p62 and LC3 can assist clinical diagnosis and guide follow-up comprehensive treatment.

Objective:To investigate the incidence characteristics and influencing factors of non-alcoholic fatty liver disease (NAFLD) in rural Uyghur ethnic group residents in Xinjiang Production and Construction Corps and to provide scientific evidence for early identification and prevention of NAFLD for residents.Methods:A total of 10 158 participants were included from the Xinjiang Uygur ethnic group population cohort. A prospective cohort study and Cox proportional hazards regression model analysis were used to explore the influencing factors and clustering of NAFLD, and the dose-response relationship between related biochemical indicators and the risk of NAFLD was studied using a restricted cubic spline.Results:The cumulative incidence rate of NAFLD was 6.9%, and the incidence density of NAFLD was 12.06/1 000 person-years. The incidence density of NAFLD in females was higher than in males (14.72/1 000 person-years vs. 9.17/1 000 person-years, P<0.001). The incidence density of NAFLD gradually increased with age in the total population, both men and women (all P<0.001). In the general population, an education level of junior high school or above was a protective factor for NAFLD, while older age, divorce, widowhood, overweight, obesity, hypertension, increased glomerular filtration rate, decreased HDL-C, increased LDL-C, and increased ALT were risk factors for NAFLD. Estimated glomerular filtration rate (eGFR), HDL-C, LDL-C, and ALT were non-linearly correlated with the incidence of NAFLD, and there was a significant dose-response relationship between them. Only 19.1% of residents had no NAFLD risk factors; over 80.9% had ≥1 NAFLD risk factors. The risk of NAFLD increased with the number of risk factors. Conclusions:The incidence of NAFLD in rural Uygur ethnic group residents in Xinjiang Production and Construction Corps was relatively low, but most residents had one or more risk factors for NAFLD. Prevention and control of NAFLD in this population cannot be ignored. In addition, people of older age, divorced or widowed, low education level, overweight or obese, hypertension, and abnormal eGFR, HDL-C, LDL-C, and ALT were the high-risk groups of NAFLD that need to be paid attention to in this population.

Objective:To explore the risk factors of pinhole infection in patients with external fixators, and build a risk prediction model.Methods:From January 2018 to June 2019, the data of patients ( n=300) with external fixators in the Department of Trauma and Orthopedics, South Hospital, South Medical University, were selected by retrospective survey, and were divided into infection group and non-infection group according to whether pinhole infection occurred in the postoperative case records. Single factor analysis and Logistic regression analysis were used to establish the risk factors of pinhole infection and its prediction model. The grade of risk prediction was constructed by the assignment method. Results:Among 300 patients with external fixators, 103 (34.33%) had pinhole infection and 197 (65.67%) had no infection. Logistic regression analysis showed that basic disease [ OR=4.726 (one of diabetes, pulmonary infection), 17.053 (two of diabetes, pulmonary infection, cardiovascular diseases) ], postoperative albumin [ OR=0.082 (<25 g/L) ], postoperative hemoglobin [ OR=3.715 (>90-120 g/L), 9.720 (>60-90 g/L), 7.338 (30~60 g/L) ], intraoperative bleeding volume [ OR=2.196 (200-400 ml), OR=3.256 (>400 ml) ] and the type of disinfectant [ OR=3.897 (chlorhexidine), 3.625 (iodophor + chlorhexidine) ] were risk factors for pinhole infection in patients with external fixators ( P<0.05). The constructed model was divided into high-risk group (≥ 7 points), higher-risk group (5-6 points), medium-risk group (4 points), low-risk group (3 points) and lower-risk group (0-2 points) . Conclusions:The model can well predict the risk of pinhole infection of orthopedic external fixator, provide reference for medical and nursing staff to identify the risk of external fixation infection in time, and prevent the occurrence of infection as soon as possible.
