Objective To explore the effect of Bailing capsule on epithelial-mesenchymal transition( EMT) in rats with adenine-in-duced tubulointerstitial fibrosis. Methods Tubulointerstitial fibrosis animal models were established and SD rats were divided into mo-del group ( n = 30), treatment group ( n = 30) and control group( n = 30), randomly. Experimental rats were harvested at 7 w, 12 w,17 w after onset of experiment and functional evaluations were performed. Histology, immunohistology were examined to investigateboth histolopathology changes and the expression of bone morphogenic protein-7 (BMP-7), transforming growth factor-β1 (TGF-β1 )and a-smooth muscle actin (α-SMA) in kidneys at three time points mentioned above, respectively. Results Compared with controlgroup, 24 h urinary protein in model group lost increasingly and significantly difference appeared at three time points relative to controlgroup ( P < 0.01 ). Urinary NAG in model group was markedly higher than that in control group from 7 w after onset (P < 0.01 ) andwas increasingly raised at 12 w and 17 w (P<0.01). The value of blood BUN and Cr in model group increased at 7 w (P>0.05) rel-ative to control group. There was significant difference at 12 w and 17.w (P < 0.01 ). Histologically, kidneys in model group, at 7 w,exhibited tubular casts and gently tubular dilation, granuloma in cortex, mononuclear cells infiltration in tubulointerstitial areas, andmild interstitial fibrosis. At 12 w, the degree of tubular injury and tubulointerstitial fibrosis gradually aggravated. Up to 17 w, diffusetubular dilation or atrophy was observed and focal tubules disappear. Diffuse interstitial fibrosis was exhibited. In normal kidneys, im-munohistochemistry suggested that the light expression of BMP-7 was detected in proximal renal tubular epithelial cells and marked ex-pression was identified in distal tubule, collecting duct, and renal tubular epithelial in junction area between cortex and medulla. How-ever, the expression of BMP-7 in kidneys of model group significantly decreased with increasing tubulointerstitial fibrosis and was nega-tive correlation with the expression of TGF-β1(r = -0. 981 P<0.01) and α-SMA (r= -0.975 P<0.01). Bailing capsule ad-ministration protected the expression of BMP-7 and reduced TGF-β1 and α-SMA expression before 12 w(P< 0.01 ). Conclusions Ourstudy shows an anti-fibrotic reno-protective function of Bailing capsule in rats with tubulointerstitial fibrosis via prevention of epithelial-mesenchymal transition at early stage. However, the beneficial effect lost with increasing tubulointerstitial fibrosis.

Through scale-up cultivation of Eriobotrya japonica suspension cells using WAVE bioreactor, the cell growth and ursolic acid (UA) accumulation were studied. The comparison test was carried out in the flask and the reactor with cell dry weight (DW) and UA content as evaluation indexes. The culture medium, DW and UA content were compared in 1 L and 5 L working volumes of bioreactor. The orthogonal test with main actors of inoculation amount, speed and angle of rotation was developed to find the optimal combination, in 1 L working volume of bioreactor. DW of the cell growth and the UA content in bioreactor were higher than those of the shaker by 105.5% and 27.65% respectively. In bioreactor, the dynamic changes of elements in the fluid culture, the dry weight of the cell growth and the UA content in 1 L and 5 L working volumes were similar. Inoculation of 80 g, rotational speed of 26 r · min(-1), and angle of 6 ° was the optimal combination, and the cell biomass of 19.01 g · L(-1) and the UA content of 27.750 mg · g(-1) were achieved after 100 h cultivation in 1 L working volume of bioreactor. WAVE Bioreactor is more suitable than flasks for the E. japonica cell suspension culture, and culture parameters can be achieved from 1 L to 5 L amplification.

Objective To assess the prevalence of carotid atherosclerosis in adult patients with KaschinBeck disease(KBD) in endemic area, and to investigate the association between KBD and atherosclerosis. Methods B-mode ultrasound was used to investigate carotid atherosclerosis in patients with KBD over 40 years old in Shanhe farm and Shangzhi city and residents in Shuangcheng county in 2009. Ultrasonography images were saved and graded according to intima media morphology. Results The prevalence rates of carotid atherosclerosis in patients with KBD from the 5 villages affiliated to Shanhe farm were 50.0%(26/52),37.3%( 19/51 ),42.5%(30/71 ),58.2% (39/67) and 44.0% (22/50) , respectively. The prevalence rates of carotid atherosclerosis in patients with KBD from the 5 villages affiliated to Shangzhi city were 63.0% (34/54), 45.3% (24/53), 47.2% (25/53), 60.0% (30/50)and 51.9% (28/54), respectively. The prevalence rates of carotid atherosclerosis in people without KBD in the 5 control villages affiliated to Shuangcheng county were 63.9% (46/72),43.1% (31/72),57.1% (40/70),46.9% (30/64) and 53.0%(35/66), respectively. Ten villages in KBD endemic area and 5 villages in control area were investigated. The prevalence rates of carotid atherosclerosis in the 15 villages were standardized and compared by Wilcoxon test. The differences were not significant between two KBD endemic areas and one control( T = 25.0,24.5,all P > 0.05). There was no significant difference in prevalence of atherosclerosis in the 3 areas(x2 = 0.36, P>0.05). Comparing the severity of carotid atherosclerosis in 3 locations, the difference was statistically significant (x2 = 15.28, P < 0.05) and there was significant difference statistically between the subjects in Shangzhi city and that in the control group(x2 = 8.92, P < 0.05). There was no significant difference between the detection rate of atherosclerosis and the severity of KBD, and similar results in the grade of atherosclerosis and the severity of KBD were found (x2 = 1.88,5.07, all P > 0.05). Conclusions The prevalence rate of carotid atherosclerosis in historical endemic area in Heilongjiang province is not higher than that in the control area.

OBJECTIVETo explore the mechanism of the eye-acupuncture for treatment of acute cerebral ischemia-reperfusion injury.
METHODSThirty-two healthy SD rats were randomly divided into a normal group, a sham operation group, a model group and an eye-acupuncture group, 8 rats in each group. The rat model of cerebral ischemia-reperfusion was established with thread occlusion method in the model group and the eye-acupuncture group. The eye-acupuncture group was treated by eye-acupuncture at "liver region", "upper energizer area", "lower energizer area" and "kidney region" for 20 min immediately after reperfusion and at 30 min before sampling. No treatment was done in the normal group and the sham operation group, and no thread occlusion was performed in the sham operation group. The Neurologic impairment was scored and the methods of immunohistochemistry staining, western-blotting and real-time fluorescent quantitation polymerase chain reaction (RQ-PCR) were taken to detect the expression of the aquaporin protein 4 (AQP4) and its mRNA in cerebral cortex after reperfusion for 3 hours.
RESULTSThe neurologic impairment score of 1.50 +/- 0.54 in the eye-acupuncture group was significant lower than 2.63 +/- 0.92 in the model group (P < 0.01). The expression of the AQP4 protein by immunohistochemistry and western-blot respectively were 116.33 +/- 10.24 and 0.53 +/- 0.04 in the normal group, 118.97 +/- 12.72 and 0.55 +/- 0.07 in the sham operation group, and 129.30 +/- 18.36 and 0.67 +/- 0.08 in the eye-acupuncture group, with statistical significance compared to 150.88 +/- 15.82 and 0.94 +/- 0.04 in the model group (all P < 0.01), and there were significant differences between the eye-acupuncture group and the normal group (both P < 0.01). The tendency in the expression of AQP4 protein and its mRNA in all the group were almost the same.
CONCLUSIONThe eye-acupuncture therapy can relieve the cerebral ischemia-reperfusion injury and the protective mechanism is related to the downregulation of the cerebral AQP4 expression.

The preliminary metabolic profile of total diterpene acid (TDA) isolated from Pseudolarix kaempferi was investigated by using in vivo and in vitro tests. Pseudolaric acid C2 (PC2) was identified as the predominant metabolite in plasma, urine, bile and feces after both oral and intravenous administrations to rats using HPLC-UV and HPLC-ESI/MS(n), and demethoxydeacetoxypseudolaric acid B (DDPB), a metabolite proposed to be the glucoside of PC2 (PC2G), as well as pseudolaric acid C (PC), pseudolaric acid A (PA), pseudolaric acid A O-beta-D glucopyranoside (PAG), pseudolaric acid B O-beta-D glucopyranoside (PBG) and deacetylpseudolaric acid A (DPA) originated from TDA could also be detected. It was demonstrated by tests that the metabolism of TDA is independent of intestinal microflora, and neither of pepsin and trypsin is in charge of metabolism of TDA, TDA is also stable in both pH environments of gastric tract and intestinal tract. The metabolites of TDA in whole blood in vitro incubation were found to be PC2, DDPB and PC2G, which demonstrated that the metabolic reaction of TDA in vivo is mainly occurred in blood and contributed to be the hydrolysis of plasma esterase to ester bond, as well as the glucosylation reaction. These results clarified the metabolic pathway of TDA for the first time, which is of great significance to the in vivo active form and acting mechanism research of P. kaempferi.

In this study, the rat type 2 diabetes mellitus (T2DM) model was established through tail vein injection with low dose of streptozotocin (STZ) and high fat diet for 8 weeks, and then treated with Jiaotai Pill. The oral glucose tolerance test (OGTT), fasting serum insulin (FINS), free fatty acid(FFA) levels and blood lipid were assayed. HOMA-IR was calculated. Pancreatic pathology was performed. And pancreatic triglyceride (TG) content was examined by the lipid extraction method. Pancreatic islet cell apoptosis were detected by terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). According to the results, the model group showed abnormal OGTT, increased FINS, HOMA-IR, FFA, lipid disorder, obvious fat accumulation and significantly increased TG content in pancreatic tissues, and enhanced pancreatic islet cell apoptosis. Compared with the model group, the Jiaotai Pill group displayed improved OGTT, reduced FINS, HOMA-IR, FFA, recovered lipid disorder, decreased fat accumulation and significantly declined TG content in pancreatic tissues, and lowered pancreatic islet cell apoptosis. In summary, Jiaotai pill could effectively treat type 2 diabetes in rats. Its mechanism may be related to the reduction in pancreatic fat accumulation and islet cell apoptosis.

OBJECTIVETo improve the diagnosis and treatment of testicular teratoma in children by analysis of clinical data.
METHODSWe retrospectively analyzed the clinical data about 64 cases of testicular teratoma treated in the Children's Hospital of Chongqing Medical University from 1995 to 2014.
RESULTSSixty-one of the cases presented painless scrotal mass with a sense of bearing down and the other 3 cases were confirmed because of empty scrotum diagnosed as cryptorchidism. The level of serum alpha fetal protein ( AFP) was obviously increased in 46 cases but normal in the other 18 preoperatively. Ultrasonography manifested abnormal inhomogeneous echo zones with calcification or necrosis. X-ray examination presented patchy or curvilinear high-density shadows in 28 cases. Forty-one of the patients underwent testis-sparing surgery (TSS) , 20 received high inguinal orchiectomy, and 3 refused surgical treatment. Pathological examination revealed 3 mature germinal layers in the 49 cases of mature teratoma and immature germinal tissue, including the original neural tube, and 11 cases of immature teratoma. The mature cases were exempted from chemotherapy, while the immature cases received the combination of cisplatin, etoposide, and bleomycin (PEB). The patients were followed up for 2 years postoperatively, which revealed no recurrence or metastasis.
CONCLUSIONMost children with testicular teratoma presented painless scrotal mass with a sense of bearing down and with abnormal serum AFP in most cases. Ultrasonography and plain radiography of the scrotum contribute to the diagnosis of the tumor. TSS is the main treatment option and intraoperative frozen-section can help the surgeons decide on the surgical mode. Postoperative chemotherapy is necessitated for immature teratoma but not for mature cases.
