Neurogenic bladder caused by herpes zoster is not common.An 86 years old male patient with 6 months of dysuria and urinary retention caused by herpes zoster underwent sacral neuromodulation (SNM) operation. The symptoms of dysuria and fecal incontinence were improved significantly after operation.

Objective To explore the radiosensitivity ofβ-elemene on Colo320 cells transplanted tumor in nude mice and its molecular mechanisms.Methods Colo320 cells transplanted tumor model was established by cell suspension inoculation in nude mice.Then the transplanted mice with 0.8-1.0 cm3 tumor were randomly divided into 4 groups:control,β-elemene (40 mg/kg),radiation (4 Gy),andβ-elemene (40 mg/kg)+ radiation (4 Gy) groups,with four to five mice in each.Tumor weight and morphology were observed in each group.In addition,the apoptosis of tumor cells was measured by TUNEL and the expression of Fas gene was detected by immunohistochemistry.Results The nude mice transplanted tumor model was successfully established.Compared with that in control and simple radiation groups,tumor weight was significantly decreased inβ-elemene combined with irradiation group (P <0.05).At the same time,the apoptosis rate and the expression of Fas gene in tumor cells were significantly increased (P <0 .0 5 )inβ-elemene combined with irradiation group compared with control and simple radiation groups. Conclusion β-elemene could enhance the radiosensitivity of Colo320 cells transplanted tumor in nude mice probably by inducing Fas-mediated apoptosis of tumor cells.

Objective To investigate the function of apoptosis in the renal injury by observing change of renal pathology and ultrastructure in the rat with obstructive jaundice(OJ) and if salvia miltiorrhiza(SM) can lighten the renal dysfunction of obstructive jaundice.Methods A total of 100 adult Sprague-Dawley rats were studied.Among them,the 80 models of obstructive jaundice were established by ligating bile duct(BDL),then divided into two groups: the OJ rats administered daily abdomen injections of SM(1.7g per rat) after operation of bile duct ligation(the SM group,n= 40);the OJ rats receiving only the same normal saline(the OJ group,n=40).The other rats with sham operation receiving only normal saline(the control group,n=20).Three groups of rats were sacrificed in groups at postoperation 1,2,3 and 4 week,respectively.Then serum BUN & Cr were tested and renal change of histopathology and ultrastructure were observed;Apoptosis of renal tissue were assayed by TUNEL method.Results With the time of BDL extending,the value of serum BUN & Cr increased;Apoptotic cells increased in renal tissue.After treatment with SM,the injury degree of renal function and histopathologic changes decreased.Conclusion Obstructive jaundice can lead to renal injury.Apoptosis had an important effect on renal function injury in the rat with obstructive jaundice.Salvia miltiorrhiza can ease the degree of renal function injury.

Objective To investigate the relationship of the expression of Bcl-2 and Bax protein with apoptosis of renal tubular epithelia in rats with obstructive jaundice(OJ).Methods A total of 60 adult Sprague-Dawley(SD) rats were divided into two groups: OJ rats by ligating bile duct(OJ group,n= 40) and the sham-operation rats(the control group,n=20).The two groups of rats were sacrificed at postoperative 1,2,3 and 4 week,respectively.Then serum BUN and Cr levels were tested and renal histopathological and ultrastructural changes were observed.Apoptosis of renal tissues was assayed by TUNEL method.The immunohistochemical Elivision~(TM) technique was adopted for detecting the Bcl-2 and Bax protein expression.Results With the time of OJ prolonging,the value of serum BUN and Cr increased;apoptotic cells of renal tubular epithelia increased.There were obvious differences in Bcl-2 and Bax protein expression of between OJ and control groups(P

Objective To investigate effects of hyperbaric oxygen (HBO) therapy on C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) levels in patients with moderate or severe traumatic brain injury (TBI)and to analyze its therapeutic efficacy. Methods One hundred and eight patients with moderate or severe TBI were randomly divided into a control group (54 cases) and an HBO adjunctive therapy group (HBO group, 54 cases).Both groups received essential neurosurgical treatment and conventional drug treatment, and the HBO group was given one session of HBO therapy in addition. Serum CRP and TNF-α were detected, and the scores on the Glasgow coma scale (GCS) were measured before and after treatment. CRP was detected by turbidimetric immunoassay and TNF-α using ELISA. Glasgow outcome scale (GOS) scores were evaluated in a follow-up 6 months after injury. Results Average CRP, TNF-α and GCS measurements showed no statistically significant difference between the groups before treatment. After treatment, CRP and TNF-α were significantly lower and GCS scores significantly better in both groups, but patients in the HBO group were, on average, significantly better than the controls on all three measures.Six months later, GOS evaluation gave a significantly larger number of patients with a better prognosis in the HBO group compared with the controls. Conclusion HBO therapy can significantly decrease serum CRP and TNF-α after severe TBI, thus enhancing therapeutic efficacy.

Objective To investigate the efficacy of hyperbaric oxygen combined with donepezil in the treat-ment of patients with vascular dementia(VD). Methods Sixty-four patients with VD were randomly divided into a control group(donepezil group,n=32)and a treatment group(hyperbaric oxygen combined with donepezil,n=32).The course of treatment was 12 weeks.All patients were tested using the Mini-Mental State Examination(MMSE)and Hasegawa's dementia scale(HDS)before and after treatment. Results After 12 weeks of treatment,the MMSE scores and HDS scores of patients increased significantly in both the control and treatment groups.There were signifi-cant differences between the control and treatment groups in terms of MMSE and HDS scores.Conclusion Hyperbar-ic oxygen combined with donepezil could significantly improve cognition in VD patients.

Objective To explore the potential role of apolipoprotein A5 (ApoA5) on the hypertriglyceridemia (HTG)-lowering effects of statin. Methods Twenty-four Sprague-Dawley rats were assigned to 3 groups:(1)control group, with no special treatment. (2) HTG group, treated with 10% fructose water for 6 weeks. (3) statin 4 weeks. Body weight, fasting plasma lipids, and the hepatic expressions of ApoA5 and PPARα were determined. In separate in vitro experiments, the effects of atorvastatin on triglyceride (TG) and the expressions of ApoA5 and PPARα in HepG2 cells were tested. Results (1) Plasma TG was higher in HTG group than in controls group, which was significantly reduced in statin group (both P ＜ 0. 05). (2) Rat hepatic ApoA5expression in HTG group was significantly lower than in control group and it was significantly higher in statin group than in HTG group (both P＜0. 05). (3) Similarly, rat PPARα mRNA expression in HTG group was lower than in control group and it was higher in statin group than in HTG group (both P ＜ 0.05). (4) Statin significantly upregulated the expressions of ApoA5 and PPARα and decreased TG in HepG2 cells, which was blocked in the presence of PPARα inhibitor. Conclusion Upregulation of ApoA5 expression contributes to TG lowering effect of statin via PPARα signaling pathway.

Objective To detect the expression of KiSS-1, KiSS-1R and MMP-9 in hepatocellular carcinoma (HCC). To study the correlation of KiSS-1, KiSS-1R and MMP-9 expression with invasion and metastasis of HCC, and to explore the underlying mechanisms. Methods The expression of KiSS-1 , KiSS-1R mRNA in 33 HCC samples, 26 non-neoplastic adjacent liver tissue samples and 13 non-neoplastic distant liver tissue samples were detected by RT-PCR. Tissue chips were constructed by modified manual tools, which contained HCC, non-neoplastic adjacent liver tissues, non-neoplastic distant liver tissues, normal liver tissues and intrahepatic metastasis lesions. The expression of KiSS-1 and MMP-9 protein was determined by tissue chips, immunohistochemistry and semi-quantitative image analysis in 150 HCC, 137 non-neoplastic adjacent liver tissue, 98 non-neoplastic distant liver tissues, 16 normal liver tissues and 37 intrahepatic metastasis lesion samples. Results The results of RT-PCR showed that compared with the non-neoplastic adjacent liver tissues and the non-neoplastic distant liver tissues, the expression of KiSS-1 mRNA in HCC was significantly lower (P＜0.01). The expression of KiSS-1R mRNA did not changed in HCC and non-neoplastic liver tissues (P＞0.05). The expression of KiSS-1 protein was lower in HCC with metastasis and in clinical stage Ⅲ than that in those with non-metastasis, and in clinical stages Ⅰ and Ⅱ . It was also higher in the primary than in the metastasis lesions (P＜0.01, respectively). The expression of MMP-9 was higher in tumors having peplos invasion and metastasis than in those with negative peplos invasion and non-metastasis. It was lower in the primary than the metastasis lesions (P＜0. 01, respectively).Negative correlation between KiSS-1 and MMP-9 expression was found in HCC(r=- 0.340,P＜0.01). Conclusions The imbalance between KiSS-1 and MMP-9 expression might play an important role in enhancing the invasive and metastatic capacity of HCC. Loss of KiSS-1 expression might predict an aggressive clinical behavior and was associated with metastatic potential in HCC.
