Objective To investigate the effects of Shugan Huoxue Huatan Decoction (SHHD) on non-alcoholic steatohepatitis (NASH) of rats. Methods 32 SD male rats were randomly allocated into 4 groups:normal group, model group, Dongbao Gantai (DBG) group, SHHD group. NASH model was induced by hyperlipid diet. General condition and pathological changes of liver tissues were observed. Liver function, blood lipids, liver tissue Hyp and serum LEP were dectected. Fasting insulin resistance index (FIRI) was evaluated according to the levels of fasting blood glucose (FBG) and fasting serum insulin (FINS). Results Compared with model group, SHHD had the effects of improving liver function and blood lipids, decreasing liver tissue Hyp, LEP and FIRI siginificantly. Conclusion Inhibiting leptin and insulin resistances, enhancing the lipid metabolism are probably the main mechanisms of SHHD in preventing and treating NASH.

Objective To investigate the effect of advanced glycation end products(AGEs)on expression of vascular endothelial growth factor(VEGF)in rabbit retinal M?ller cells in vitro.Methods We successfully cultured rabbit retinal M?ller cells and made AGEs-BSA as well as its control in vitro.Study with M?ller cells were divided into AGEs-BSA group,AGEs-BSA control group and blank control group.AGEs-BSA group and AGEs-BSA control group were respectively treated with 5 different concentration series of AGEs-BSA and AGEs-BSA control and cultured for 3,6 and 9 days,while blank control group was incubated without any intervention.Then VEGF expression in M?ller cells was observed by immunocytochemistry(ICC).Results Compared with control group,VEGF expression in cultured retinal M?ller cells was significantly enhanced in AGEs-BSA group.And the effects were in the time-and concentration-dependent manners.Conclusions AGEs increases VEGF expression in rabbit retinal M?ller cells in vitro,which indicates that AGEs may promote the progression of diabetic retinopathy(DR)through the induction of VEGF expression.

Objective To verify the safety and advantages of total transperitoneal laparoscopic nephroureterectomy (ttLNU) in the treatment of upper urinary tract urothelial carcinoma (UTUC).Methods From Jun.2013 to Jun.2014,there were 13 UTUC patients treated with ttLNU,including 7 males and 6 females.The mean age was 70.4 ± 8.3 yrs,and BMI was 23.3±4.1.Of them,11 cases were diagnosed with renal pelvis carcinoma,6 in the left and 5 in the right.2 cases were diagnosed with left ureteral carcinoma.TNM stages were T1-T3N0M0.Patients were put on lateral position and the position was not changed during the operation.A ttLNU was performed,and the specimen was removed from the middle extended inferior umbilical incision.Results The mean operative time was 188±33 (150-240) min,the intraoperative blood loss was 150.5±60.1 (50-700) ml,and the time of out-of-bed activity was between 1 and 4 d.The mean postoperative drainage time was 6.8±4.6 (3-6) d.The mean postoperative bowel function recovery time was 1.5± 1.0 (2-4) d and postoperative hospital stay was 12.8±7.0 (3-27) d.The ttLNU procedures were successfully performed in all cases without conversion to open surgery.Pathological results showed urothelial carcinoma in all cases,including 8 high grade and 5 low grade.All the surgical margins were negative.The followed up was from 2 to 12 mon,and there was no tumor recurrence and metastasis found.Conclusions Total transperitoneal laparoscopic nephroureterectomy in the treatment of upper urinary tract urothelial carcinoma is characterized by short operative time,low blood loss,decreased trauma and quick recovery.This is a safe and effective treatment option for the treatment of upper urinary tract urothelial carcinoma.

OBJECTIVETo evaluate the relationship between CT findings and immunohistochemical types of gastrointestinal stromal tumors (GIST).

METHODSCT imaging and clinicopathological data of 85 patients with GIST were analyzed retrospectively. The CT findings of GIST including lesion location, size, contour, boundary, tumor growth pattern, degree of enhancement, necrosis and calcification, were summarized and compared with the immunohistochemical types of the GIST.

RESULTSOf the 85 patients, smooth muscle differentiation was in 26 cases (30.6%), neural differentiation in 20 (23.5%) , both smooth muscle and neural differentiation in 10 (11.8%) and no obvious differentiation in 29 (34.1%) cases. GISTs occurred in the duodenum were more frequently seen in muscle type than in any other types, GIST with smooth muscle differentiation had higher prevalence of huge mass (larger than 10 cm), distinctive enhancement and extensive necrosis than other types (P < 0.05). There was no significant difference in the relationships of immunohistochemical types with tumor contour, boundary, growth pattern and calcification among the four groups of GIST (P > 0.05).

CONCLUSIONSCT scan is the most important and effective method for diagnosis of GIST. Analyzing CT signs has some potential value in judgmet of immunohistochemical types of GIST.

Objective To investigate the clinical efficacy of intraoperative fluorouracil implant combined with raltitrexed chemotherapy in advanced gastric cancer. Methods The clinical data of patients with advanced gastric cancer from November 2013 to November 2014 were retrospectively analyzed. The patients were divided into 2 groups according to intraoperative treatment method. Sixty-two cases (observation group) received intraoperative fluorouracil implant combined with raltitrexed regional chemotherapy, and 54 cases (control group) were not given the intraoperative chemotherapy drugs. The postoperative ventilation time, incidence of complications, peripheral blood white blood cell and platelets 1st, 3rd, 5th and 7th day after operation, cumulative recurrence rate and cumulative survival rate 3 years after operation were compared between 2 groups. Results There were no significant differences in postoperative ventilation time and incidence of complications between 2 groups (P > 0.05). The white blood cell 1st and 3rd day after operation in observation group was significantly lower than that in control group: (5.21 ± 1.03)×109/L vs. (6.52 ± 1.08)×109/L and (5.29 ± 1.11)×109/L vs. (6.37 ± 1.06)×109/L, the platelet 1st, 3rd and 5th day after operation in observation group was significantly lower than that in control group: (172.64 ± 31.48) × 109/L vs. (188.34 ± 30.05) × 109/L, (175.81 ± 31.77) × 109/L vs. (190.36 ± 31.12) ×109/L and (178.46 ± 32.04) ×109/L vs. (191.18 ± 31.29) ×109/L, and there were statistical differences (P＜0.05); but the white blood cell and platelets in 2 groups were in the normal range at all time points. The 3-year cumulative recurrence rate in the observation group was significantly lower than that in control group: 75.8% (47/62) vs. 83.3% (45/54), the 3-year cumulative survival rate was significantly higher than that in control group: 71.0% (44/62) vs. 51.9% (28/54), and there were statistical differences (P＜0.05). Further analysis of patients with recurrent 3 years after operation, the incidence of local recurrence and extensive peritoneal metastasis in observation group was significantly lower than that in control group: 40.4% (19/47) vs. 68.9% (31/45), and there was statistical difference (P＜0.01). Conclusions It is a safe and effective treatment for intraoperative fluorouracil implant combined with raltitrexed regional chemotherapy to inhibit local recurrence and peritoneal metastasis in patients with advanced gastric cancer.

Cholestatic liver disease is a common disease of the hepatobiliary system. Its etiology and pathogenesis are complex. The establishment of an appropriate animal model of cholestatic liver disease is the basis for further study of its pathogenesis and prevention. This study summarized the existing modeling methods， mechanisms， and characteristics of this model， and analyzed its alignment with the clinical disease and syndrome characteristics of integrated traditional Chinese and Western medicine based on the modern clinical diagnostic criteria and traditional Chinese medicine syndrome characteristics of cholestatic liver disease， so as to provide a reference for establishing standard animal models and evaluation methods for cholestatic liver disease that accord better with the clinical practice of integrated traditional Chinese and Western medicine.

Saponins are widely found in various Chinese medicines such as Ginseng Radix et Rhizoma， Notoginseng Radix et Rhizoma， and Bupleuri Radix. They possess multiple biological activities， including anti-inflammatory， antioxidant， antitumor， hepatoprotective， lipid-lowering， and hypoglycemic effects. They play an important role in the prevention and treatment of diseases such as acute lung injury， hyperlipidemia， and diabetic cardiovascular complications， and hold significant research potential and value. Metabolism-related fatty liver disease is a prevalent chronic liver disease characterized by excessive lipid accumulation in hepatocytes. According to the "multiple hit" theory， its occurrence is the result of systemic homeostasis disorder， influenced by abnormal lipid metabolism， oxidative stress， inflammation， insulin resistance， mitochondrial dysfunction， and intestinal microbiota. However， there is currently no effective treatment available in clinical practice. Recent studies have found that Chinese herbal saponins can alleviate metabolism-related fatty liver disease through various pathways， including regulating abnormal lipid metabolism， inhibiting inflammatory responses， alleviating oxidative stress， reducing insulin resistance， improving mitochondrial dysfunction， modulating intestinal flora， inhibiting hepatocyte programmed death， regulating liver autophagy， and correcting immune imbalances. Therefore， this review summarized the pharmacological effects and related mechanisms of Chinese herbal saponins in improving metabolism-related fatty liver disease in recent years， aiming to provide a theoretical reference for the clinical application and experimental research of Chinese herbal saponins in the prevention and treatment of metabolism-related fatty liver disease.

Objective: To investigate the expression of integrin β₃ in the endometrial implantation window of patients with cesarean scar and infertility, and its correlation with endometrial receptivity. Methods: A total of 40 patients with previous cesarean scar defect (PCSD) secondary infertility treated in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from April 2018 to December 2019 were enrolled as the observation group.The natural cycle of 40 normal women who were examined in our hospital at the same time were selected as the control group.The two groups were enrolled in the endometrium of the glandular epithelial cells for MMP-9, TIMP-1 and LIF immunohistochemical staining, and statistical analysis was performed.The serum E₂ and P levels of the implantation group were compared.The E₂/P ratio was measured and compared, and the expression level of integrin β₃ endometrial planting window was compared. Results: The MMP-9, TIMP-1 and LIF in the observation group [(175.31±56.36), (201.46±51.34), (209.23±45.23)] were significantly lower than those in the control group [(252.35±78.43), (257.23±74.13), (298.34±72.35)] (t=5.334, 5.766, 6.023, all P<0.05), but the E₂, P and E₂/P in the observation group [(515.31±56.36)pmol/L, (53.71±8.34)pmol/L, (13.23±5.23)] were higher than those in the control group[(352.35±78.43)pmol/L, (33.13±4.13)pmol/L, (8.17±2.91)] (t=7.334, 4.251, 3.241, all P<0.05). The level of beta 3 in the observation group (0.163±0.013) was significantly lower than that in the control group (0.253±0.031) (t=4.342, P<0.05). The thickness of endometrium in the observation group [(9.12±2.03)mm] was significantly thinner than that in the control group [(12.24±2.45)mm] (t=3.226, P<0.05). Conclusion The expression of integrin β₃ in the endometrial implantation window of patients with cesarean section scar infertility has a certain influence on endometrial receptivity.

Objective To evaluate the clinical value of holographic image navigation in urological laparoscopic and robotic surgery.Methods The data of patients were reviewed retrospectively for whom accepted holographic image navigation laparoscopic and robotic surgery from Jan.2019 to Dec.2019 in Beijing United Family Hospital and other 18 medical centers,including 78 cases of renal tumor,2 cases of bladder cancer,2 cases of adrenal gland tumor,1 cases of renal cyst,1 case of prostate cancer,1 case of sweat gland carcinoma with lymph node metastasis,1 case of pelvic metastasis after radical cystectomy.All the patients underwent operations.In the laparoscopic surgery group,there were 27 cases of partial nephrectomy,1 case of radical prostatectomy,2 cases of radical cystectomy and 2 cases of adrenalectomy.In the da Vinci robotic surgery group of 54 cases,there were 51 cases of partial nephrectomy,1 case of retroperitoneal lymph node dissection,1 case of retroperitoneal bilateral renal cyst deroofing and 1 case of resection of pelvic metastasis.There were 41 partial nephrectomy patients with available clinical data for statistic,with a median age of 53.5 years (range 24-76),including 26 males and 15 females.The median R.E.N.A.L score was 7.8 (range 4-11).Before the operation,the engineers established the holographic image based on the contrast CT images and reports.The surgeon applied the holographic image for preoperative planning.During the operation,the navigation was achieved by real time fusing holographic images with the laparoscopic surgery images in the screen.Results All the procedures had been complete uneventfully.The holographic images helped surgeon in understanding the visual three-dimension structure and relation of vessels supplying tumor or resection tissue,lymph nodes and nerves.By manipulating the holographic images extracorporeally,the fused image guide surgeons about location vessel,lymph node and other important structure and then facilitate the delicate dissection.For the 41 cases with available clinical data including 23 cases of robotic-assisted partial nephrectomy and 18 cases of laparoscopic nephrectomy,the median operation time was 140 (range 50-225) min,the median warm ischemia time was 23 (range 14-60) min,the median blood loss was 80(range 5-1 200) ml.In the robotic surgery group,the median operation time was 140 (range 50-215)min,the median warm i schemia time was 21 (range 17-40)min,the median blood loss was 150(range 30-1 200)ml.In the laparoscopic surgery group,the median operation time was 160(range 80-225)min,the median warm ischemia time was 25 (range 14-60)min,the median blood loss was 50 (range 5-1 200) ml.All the patients had no adjacent organ injury during operation.There were 2 cases with Clavien Ⅱ complications.One required transfusion and the other one suffered hematoma post-operation.However,the tumors were located in the renal hilus for these 2 cases and the R.E.N.A.L scores were both 11.Conclusions Holographic image navigation can help location and recognize important anatomic structures during the surgical procedures..This technique will reduce the tissue injury,decrease the complications and improve the success rate of surgery.

OBJECTIVE: To investigate the protective effect of procyanidin B2 (PCB2) on the intestinal barrier and against enteritis in mice with trinitrobenzene sulphonic acid (TNBS)-induced colitis and explore the possible mechanism. METHODS: A mouse model of TNBS-induced colitis was established in male Balb/c mice aged 6-8 weeks. The successfully established mouse models were randomly divided into PCB2 treatment group (=10) and model group (=10) and were treated with daily intragastric administration of PCB2 (100 mg/kg, 0.2 mL) and 0.2 mL normal saline, respectively. After 4 weeks, the disease symptoms, intestinal inflammation, intestinal mucosal cell barrier function and the changes in PI3K/AKT signaling were evaluated using HE staining, immunofluorescence assay and Western blotting. RESULTS: The disease activity index of the mice was significantly lower and the mean body weight was significantly greater in PCB2 group than in the model group in the 3rd and 4th weeks of intervention ( < 0.05). The levels of colonic inflammation and intestinal mucosal inflammatory mediators IL-1β and TNF-α were significantly lower while IL-10 was significantly higher in PCB2 group than in the model group ( < 0.05). Compared with those in the model group, the mice in PCB2 treatment group showed a significantly lower positive rate of bacterial translocation in the mesenteric lymph nodes and a lower thiocyanate-dextran permeability of the intestinal mucosa ( < 0.05). Western blotting showed that PCB2 treatment significantly increased the expressions of claudin-1 and ZO-1 ( < 0.05) and significantly lowered the expression levels of p-PI3K and p-AKT in the intestinal mucosa as compared with those in the model group ( < 0.05). CONCLUSIONS PCB2 suppresses intestinal inflammation and protects intestinal mucosal functions and structural integrity by inhibiting intestinal PI3K/AKT signaling pathway, suggesting the potential of PCB2 as a new drug for Crohn's disease.
