Objective To explore the mechanism of LMWH therapy for SAP.Methods 48 wistar rats were random divided into 3 groups,sham group(S group),severe acute pancreatitis group(SAP group)and LMWH therapy group(H group).Serum amylase,IL-6,acinar cell apoptosis and the activity of NF-κB were detected and compared.Results The expression of amylase and IL-6 in SAP group was significantly higher than that in H group(P＜0.01).The apoptosis index of acinar cell in SAP group wag significantly lower than that in H group(P＜0.01),while the activity of NF-κB in SAP groupwas stronger than that in H group.Conclusions LMWH therapy may ameliorate SAP by inducing acinar cell apoptosis through suppressing the activity of NF-κB.

Objective To establish a stable HCV full-length genome replication cell model which is labeled with reporter gene and easyly to quantify intracellular HCV proteins and RNA level. Methodsneo gene was inserted into Luc-JC1 to make Luc-JC construct. Luc-JC RNA was obtained by in vitro transcription and then delivered into Huh7 cells by transfection. G418-resistant clones of Huh7 cells were obtained by selection. Clones of HCV full-length genome replication cell were confirmed by luciferase activity assay, Western blot and cleaveage of eYFP-MAVS by HCV NS3/4A protease. Then, HCV replication cell colonies were treated by different dose IFN-α in order to observe the change of luciferase activity, HCV protein and RNA level. Results At 3-4 weeks post-transfection, visible colonies were selected and stained by crystal violet. Luciferase activity and HCV NS3, NS5A protein were detected by luciferase activity assay and Western blot, respectively. Subcellular localization of eYFP-MAVS transferred from mitochondria to cytoplasms by cleavage of NS3/4A protease in cell colonies. Luciferase activity, HCV protein and RNA diminished obviously after IFN-α treatment. Conclusion A stable HCV full-length genome replication cell model labeled by reporter gene was successfully established and reporter activity can be used to indicate level of HCV proteins and RNA in cells. This cell model is a useful tool for the study on HCV pathogenesis and the screening of antiviral drugs.

Objective To investigate the efficacy of emergency vacuum sealing drainage (VSD) in the treatment of crush syndrome. Methods A total of 102 patients with crush injury were randomly screened out and divided into emergency VSD group (n = 50), delayed VSD group (n = 22) and control group (n = 30). The variances of indices of crush syndrome after VSD between three groups were analyzed. Results The vital sign, urine volume, laboratory examination results were improved and the incidence rate of crush syndrome, complications and mortality rate were significantly decreased in emergency VSD group than those in delayed VSD group and control group (P < 0.05). For patients with crush syndrome, the incidence of complications, duration of hospital stay and mortality rate were significantly decreased in emergency VSD group and delayed VSD group than those in control group (P < 0.05). Conclusion Emergency VSD can suck the exudate of the necrotic tissues and the wounds, maintain draining wounds and prevent infection and hence is helpful to prevent and treat the crush syndrome.

A chiral LC-MS/MS method for the simultaneous analysis of desvenlafaxine (DVS) enantiomers in human plasma was developed and applied to a pharmacokinetic study on 12 Chinese healthy volunteers. d6-Desvenlafaxine was used as internal standard (IS). Chromatographic separation was performed on the Astec Chirobiotic V chiral column (150 mm x 4.6 mm, 5 μm). The assay was linear over the concentration range of 0.500-150 ng x mL(-1) for both enantiomers (r2 > 0.99). The method was successfully applied to a stereoselective pharmacokinetic study of 100 mg desvenlafaxine sustained release tablets on 12 Chinese healthy volunteers under fasting conditions. The results showed that the pharmacokinetic parameters were similar to both enantiomers in Chinese healthy volunteers. The AUC(0-t), and C(max) of the two enantiomers were about 1.5 times higher than those of blacks and whites reported in the literature.

OBJECTIVETo investigate the role of endogenous hydrogen sulfide (H2S) in erectile dysfunction (ED) induced by androgen deficiency.

METHODSWe randomly divided 30 eight-week-old healthy male SD rats into six groups: 2-week control (A), 4-week control (B), 2-week castration (C), 4-week castration (D), 2-week castration + androgen replacement (E), and 4-week castration + androgen replacement (F), those in groups E and F subcutaneously injected with testosterone propionate (TP) at the physiological dose of 3 mg/kg per day after castration, while those in the other groups with isodose oil instead. At 2 and 4 weeks after operation, we determined the level of serum testosterone (T) , intracavernous pressure (ICP) , mean carotid arterial pressure (MAP) of the rats, measured the concentration of H2S in the plasma and corpus cavernosum tissue, and detected the expressions of cystathionine-P3-synthase (CBS) and cystathionine-gamma-lyase (CSE) by immunohistochemistry and Western blot.

RESULTSThe serum T level was significantly lower in group C ([0.63 +/- 0.15] nmol/L) than in A ( [ 16.55 +/- 4.17] nmol/L) and E ( [ 18.99 +/- 4.62] nmol/L) (P <0.05), as well as in group D ([0.70 +/-0.22] nmol/L) than in B ([15.44 +/-5.18] nmol/L) and F ([20.99 +/-6.41] nmol/L) (P <0. 05) , and so were ICP/MAP after 5 and 7 V electrical stimulation of the pelvic ganglia (P <0. 05) , H2 S concentration (P <0.05), and the expressions of CBS and CSE (P <0.05). The expressions of CBS and CSE proteins were also significantly decreased in group C as compared with D (P <0.05).

CONCLUSIONThe reduced expressions of CBS and CSE may inhibit the H2 S signaling pathway, which might be one of the mechanisms underlying androgen deficiency-induced ED in rats.

OBJECTIVETo evaluate the clinical outcomes of percutaneous intervertebral foramina endoscopic lumbar discectomy for elder patients with lumbar spinal stenosis syndrome.

METHODSFrom July 2006 to July 2011, 60 elder patients with lumbar spinal stenosis syndrome were treated with surgical operation, including 32 males and 28 females with an average age of (66.7 +/- 2.5) years old ranging from 72 to 83 years. These patients were divided into the traditional surgery group and percutaneous intervertebral foramina endoscopic discectomy groups (PTED group), 30 cases in each group. The index of the preoperative and postoperative, operative incision visual analogue scale (VAS) of two groups were compared. The Oswestry disability index (ODI) of two groups at 6, 24 months of the follow-up were also evaluated on activity of daily living.

RESULTSThe average operative time, the average blood loss, the number of cases using analgesic drug, hospitalization time of PTED group were better than those of the traditional surgery group (P < 0.05). The improvement of incision VAS in PTED group was better than that in the traditional surgery group (P < 0.05). All patients were followed up for 24 months at least. The ODI at 1, 24 month after operation were better than that of preoperative in two group respectively (P < 0.05), but the improvement of PTED group was better than that of the traditional surgery group (P < 0.05).

CONCLUSIONPTED has the advantages of smaller incision, less bleeding, less postoperative stay and hospitalization time, tissue trauma and quicker recovery. It is a safe and efficacious minimally invasive surgical technique for elder patients with lumbar spinal stenosis syndrome.

Objective To study the curative effect and the prognostic factors of endoscopic traumatic optic neuropathy (TON). Methods The clinical data of 53 patients with TON from 2010 to 2015 years was retrospectively analyzed. Divided the patients into the surgery group and the non-surgery group, according to whether or not accept the treatment of endoscopic optic decompression. And evaluating the potential prognostic factors in chi-square test, group t-test and multiple regression analysis. Results In 53 patients (55 eyes ), 31 eyes have no visual acuity before treated: 8 eyes’ visual acuity was improved in 16 eyes (8/16) that accepted operation; 3 eyes’ visual acuity was improved in 15 eyes (3/15) that with non-operation;24 eyes have visual acuity before treated:11 eyes’ visual acuity was improved in 14 eyes (11/14) that accepted operation;3 eyes’ visual acuity was improved in 10 eyes (3/10) that with non-operation;19 eyes’ visual acuity was improved in 30 eyes (19/30) that accepted operation, the total effective rate was 63.3%, and there was no complications happened in the patients who accepted operation. The age, eye-side, sex, visual acuity, optic canal fracture , orbit fracture , all these factors have no correlation to the prognosis (P>0.05), but the interval time between injury and operation (less than 3 days) and the way of the treatment are benefit to improve vision (P<0.05). Conclusions The endoscopic optic decompression is an effective treatment in TON, and it’s better to improve vision in 3-day after TON.
