RESULTS: The linear range of Matrine was 0.27～ 8.66 ?g(r=0.999 8) and the average recovery of Matrine was 99.52 %(RSD=0.91%,n=6). CONCLUSION: The method is simple, accurate and reproducible, and it is applicable for the quality control of Baishan tablets.

Desmoid tumor also known as aggressive fibromatosis,are rare fibroblastic tumors which are derived from deep fascia planes or muscuofascia structures.Resectable extra-abdominal and abdominal desmoid tumor should always be treated with the aim of achieving a negative margin through wide radical resection with margins above 2 cm.Ifthis is not feasible,function-sparing surgical resection is suggested.Adjuvant radiation should be considered for patients with positive margins,recirrent tumors or unresectable diseases.Intra-abdominal desmoid tumor is common in patients with familial adenomatous polyposis.It has a high recurring rate after surgical resection and therefore a high dosage of tamoxifen and sulindac are recommended as first-line treatment.Due to the variable nature of the outcome and vague reaction to drug therapy,individualized treatments,including the wait and see policy,has been widely investigated and thought to be a promising strategy for the future.

Objective To improve the rate of early diagnosis and prolong the survival of patients with gallbladder carcinoma.Method Clinical data of 111 cases of primary carcinoma of the gallbladder undergoing surgery from Jan 2002 to Dec 2010 were analyzed retrospectively.Result The preoperative diagnositic rate was 61.3％.Among the 111 cases of primary carcinoma of the gallbladder,22 patients received simple cholecystectomy,47 patients received radical resection,18 patients received extended radical resection,12 patients received palliative operation while the other 12 patients only got biopsy due to widespread intraabdominal metastasis.The 3 years survival rate of the patients was 29.7％ (33/111) while the 5 years survival rate was 9.9％ ( 11/111 ).Conclusions B-ultrasonography and CT are the mainstay for the diagnosis of primary carcinoma of the gallbladder.For those suspected of having the carcinoma,an exploration is recommended.

OBJECTIVE The status and risk factors of nosocomial infections in intensive care unit(ICU) were investigated to make the intervention strategy. METHODS Use prospective monitoring and retrospective investigation to analyze the 198 nosocomial infections patients. RESULTS The lower respiratory tract infection was the main infection in ICU,about 69.4%.The risk factors were old ages,long hospitalization time,the use of many antibiotics,severe underlying illness,invasive operation manipulation and so on. CONCLUSIONS General intervention strategy should be adopt in the control of ICU nosocomial infections to low the infection rate and raise the rate of rescue.

AIM To investigate the protective effects and mechanisms of TMP on accelerated anti-glomerulus basement membrane(GBM) antibody nephritis of rats. METHODS Model of accelerated anti-GBM nephritis was established in rats and TMP was administrated 120 mg?kg -1 ?d -1 by ip since the day before the model established, consecutively for 15 days. Content of 24h urine protein was detected after model established and rats were killed on d 7 and d 14. Contents of blood urine nitrogen (BUN) and serum creatinine (SCr) were detected. Renal cortex cytoplasm and mitochondria were produced and change of content of lipid peroxidation products malondialdehyde(MDA), activities of glutathione peroxidase(GSH-Px) and catalase(CAT) and superoxide dismutase(SOD) were investigated. RESULTS Compared with model group, TMP group showed significant inhibition in changes of proteinuria and BUN, SCr(P

Prostaglandin (PG) D_2 is one of unsaturated fatty acids with 20 carbon atoms, which is synthesized by PGD synthase (PGDS) in the brain. PGD_2 has been identified to be a sleep-inducing substance that becomes bound to the DP receptor (DPR) exclusively localized on the surface of the basal forebrain, leading to an increase in extracellular adenosine levels there. Through A_ 2A receptors (A_ 2A R), the adenosine activates neurons in the ventrolateral preoptic area (VLPO), a putative sleep center, and inhibits neurons in the histaminergic tuberomammillary nucleus (TMN), a putative wake center, via GABA to induce sleep. Studying the effect and the molecular mechanisms of sleep-induced by PGD_2 would be helpful in the development of novel sleeping drugs for more rational treatment of sleep disorders.

AIM: To explore the curative effect of different ways of silicone tube catheter for the treatment of children`s lacrimal canaliculi rupture.METHODS: A retrospective analysis from January 2014 to December 2015 were taken.According to admission time sequence,42 children with lacrimal canaliculi rupture was divided into two groups.One group was treated with single silicone tube insertion,the other was treated with annular silicone tuber insertion.The treatment results were comparatively analyzed.RESULTS: There were 4 eyes in single silicone tube group occurred fall off in 2wk to 1mo after operations because of improper nursing and the second operations were taken.There was no eye with this in annular silicone tuber groups,the difference between the two groups was significant(P<0.05).In single silicone tube group,16 eyes were cured,1 eye improved,3 eyes unchanged which were the 3 eyes with fall off.Those 3 eyes were 1 patient bitten by dog,2 bombed;the effective rate was 85%.In annular silicone tuber insertion,20 eyes were cured,2 eyes improved and the effective rate was 100%,the difference between the two groups was significant (P<0.05).CONCLUSION: Children`s lacrimal canaliculi rupture should be timely given surgical treatment,reasonable surgical treatment can achieve good operation effect.Annular silicone tube has good stability,fewer complications than single silicone tube,and clinical treatment effect is good.

Objective To investigate the efficiency of liver cancer with portal vein tumor thrombus (MPVTT),hepatic artery portal vein fistula (APVS) in patients with hepatic artery chemoembolization (TACE) combined with the clinical value of portal vein stent during treatment with APVS embolization.Methods From January 2012 to October 2014,59 cases of HCC patients who accepted the treatment of TACE + stent in portal vein embolization of + APVS surgery,companied with MPVTT and APVS were ret rospectively analyzed.The liver function,portal vein angiography and pressure at different time points were measured and compared before and after treatment,and follow-up and prognosis were recorded.Results After treatment with albumin,platelets (PLT) levels were higher than those before treatment (P ＜ 0.05),with PT values lower than before treatment (P ＜ 0.05).No statistical significance was found for aspartate aminotransferase (AST),alanine aminotransferase (ALT) before and after treatment (P ＞ 0.05).Stent implantation before and after stent implantation,the portal venous pressure of APVS embolization had signif icant difference (P ＜ 0.05).Portal venous pressure level of stent implantation was lower than before stent implantation (P ＜ 0.05).The portal venous pressure level of APVS embolization was lower than the stent implantation before and after stent implantation (P ＜ 0.05).At the 12 months after treatment,28 cases survived (47.46％);24 months after treatment,11 cases survived (18.64％) of the group;a total of 3 patients was lost to follow-up,the median survival time of the patients 24 months 16.5 months.Conclusions Liver cancer with MPVTT and APVS in the TACE combined with portal vein stent in the treatment process using APVS embolization can further improve the portal vein blood flow,and reduce the pressure of Dortal vein.
