Objective: To investigate the effect of astragalus on the serum levels of hepatocyte growth factor (HGF), renal function and the damage of renal morphology in ischemic acute renal failure (IARF). To study the protective mechanism of astragalus in IARF. Methods: The rats were pretreated with astragalus or vehicle for 3 days. IARF was induced by left renal artery clipping for 60 min, after the right kidney was removed. Biochemical parameters for serum HGF,blood urea nitrogen(BUN),creatinine(Cr) were measured and histological analyses of the kidneys were performed by tubular grading. Results: There have no significant difference between the serum HGF levels of I/R controls and the levels observed in sham-operated group (P > 0.05). Serum HGF levels in astragalus treated group was significantly increased than those of I/R control group(P < 0.01) .After 4 h of I/R, serum levels of BUN and Cr were increased in I/ R control rats compare with Sham-operated rats(P < 0.01). Astragalus treatment reduced the levels elevation(P < 0.05). Simultaneously,. I/R-induced severe damage in renal morphology were significantly ameliorated by astragalus treatment(P < 0.01). Conclusions: Astragalus pretreatment can alleviate the damage of renal function in IARF. It is may be one of the mechanisms of astragalus for protecting renal tissue in IARF that astragalus can induce the expression of HGF.

Objective To investigate the clinical manifestation of convulsive status epilepticus (CSE) associated with the outcome of children contracted this illness in order to make an effort to prevent and treat those children. Method The patients with CSE admitted from October 1998 to October 2008 were prospectively and consecutively enrolled. All the patients met the diagnostic criteria set by International Anti-epilepsy Union (ILAE) in 1993. The prognosis predictors of outcome were analyzed with the Rank sum test, Chi-square analysis and Logistic regression analysis. Results A total of 169 patients with CSE were enrolled. Of them, 92 patients were from rural areas (54.4% ). The primary cause was central nervous system infection, and the minor ones were a reduction of dose or withdrawal of the antiepileptics, and cerebral hemorrhage. The duration of CSE before treatment was longer in rural patients than in urban residents ( P < 0.01) . The duration of CSE before treatment and the total persistence time of CSE was significantly associated with the mortality 14.2% . The source of patients, the duration before treatment, and respiratory depression were independent prognostic predictor variables of CSE (P < 0.05) .Conclusions The rural patients account for the major ratio of convulsive status epilepticus. Central nervous system infection is the primary cause. The duration before treatment and total persistence time of CSE are highly related to the mortality and morbidity.

Objective To explore the clinical characteristics of localized peritoneal mesothelioma by the retrospective analysis of the clinical data and its relationship with asbestos exposure.Methods A total of 22 cases with localized peritoneal mesothelioma confirmed by pathological test and they were selected as our subjects in the Central Hospital of Cangzhou from Jan.2007 to Dec.2012.The information of all cases was collected.The incidence,asbestos exposure history,clinical manifestations,imaging studies,pathological type,immunohistochemistry and tumor markers of peritoneal mesotheliom patients were recorded or measured.Results Of 22 cases,female accounted for 68.18％.The periods from onset symptoms to treatment time was from 2 days to 1 year with an average of 83 days.Clinical symptoms were verified including localized abdominal pain (11 cases,50.00％),abdominal mass (8 cases,36.36％),abdominal distension (6 cases,27.27％),ascites (10 cases,45.45％).Patient was with increased platelet and carcinoma antigen 125.Abdominal computerized tomography showed that local mass was seen and 12 cases were with asbestos spot.Ultrasound-guided peritoneal biopsy was confirmed as the main diagnostic method followed by Laparotomy.Epithelial type was the main pathological type (19 cases,86.36％),following the fleshy tumor type and mixed type.Eighteen cases had asbestos exposure history.Conclusion Localized peritoneal mesothelioma is a rare disease.However,the incidence is high in the current region due to asbestos exposure.Abdominal pain and local mass are the main clinical symptoms,and the main pathology is epithelial typeas well as surgery is the main therapy.

Objective To observe the effect of Wenxiao Decoction in treating the patients with carotid atherosclerostic (CAS) plaque and assess the safety. Methods Sixty patients with CAS plaque were randomly allocated to treatment group (33 cases) and control group (27 cases). The control group was given routine therapy, and the treatment group was given Wenxiao Decoction additionally. And they were further divided into half-year treatment group and half-year control group, 1-year treatment group and 1-year control group. Carotid artery color Doppler ultrasound and hepatorenal function were examined before and after treatment. Results Compared with the control groups after therapy, the average numbers of plaques, maximal plaque thickness, Crouse plaque integral were decreased both in 1-year and half-year treatment groups (P<0.05, P<0.01). The plaque stability of 1-year treatment group was better than that of half-year treatment group. The average numbers of plaques, plaques size and Crouse plaque integral increased in control groups after routine therapy (P<0.05, P<0.01). Bilateral common carotid artery diameter, intima-medial thickness (IMT) and hepatorenal function had no statistical difference between before and after treatment both in treatment and control groups (P>0.05). Conclusion Wenxiao Decoction is effective and safe in treatment of CAS plaque, and plaque stability is more obvious with the extension of treatment time.

Objective To investigate the suitable treatment of post operative anastomotic recurrence after anterior resection of rectal cancer and analyze the relationship between different kinds of therapy with prognosis. Methods The clinical data of 41 cases of local recurrent rectal cancer after anterior resection admitted in our hospital from 1999 to 2009 were analyzed retrospectively. The median survival time and survival rate were calculated by Life Tables method. The influence of different kinds of treatment to prognosis was evaluated by Kaplan-Meier method and the variability was analyzed by Log-rank method. P <0.01 means statistical significance. Results Thirty-three (80.5 %) of 41 patients were recurrent in the first 3 years and the median survival time was 23 months. Seventeen (41.5 %) of 41 patients underwent radical R0 resection. The median survival time of radical resection patients and non-radical resection ones were 49 months and 18 months, respectively, and the difference was significant (χ2=12.245, P=0.000). Thirty-one patients with radiotherapy and/or chemotherapy showed a statistically longer median survival time than the other 10 patients without these adjuvant treatment (39 months and 9 months, respectively) (χ2=17.533, P =0.000). Conclusion Most post operative anastomotic recurrent of rectal cancer cases occurs in the first 3 years after primary surgery. Radical resection, radiotherapy and chemotherapy can improve the prognosis.

Objective: To learn the mutation types and hearing screening results in local newborns of Zhoushan,in order to provide evidence for prevention and early detection of deafness. Methods: The newborns in Zhoushan Maternal and Child Health Hospital from August 2015 to May 2018 were recruited and detected by matrix-assisted laser desorption ionization time of flight mass spectrometry（MALDI-TOF-MS）for twenty-two mutation sites of GJB2,SLC26A,GJB3 and 12SrRNA genes. The results of genotyping and hearing screening were analyzed and the hearing condition of abnormal newborns was followed up. Results: Among 4 029 newborns,180（4.47%）newborns were identified to carry mutations,including 94 males（4.66%）and 86 females （4.28%）. There was no statistically significant difference in the rate of carrying mutations between male and female infants （P>0.05）. Totally 135 （3.35%）newborns failed in primary hearing screening,13（9.63%）of whom carried the deafness genes;3 894（96.65%）newborns passed,167（4.29%）of whom carried the deafness gene. There was statistically significant difference in the the rate of carrying mutations between newborns who passed and failed in primary hearing screening （P<0.05）. Eleven newborns were diagnosed with hearing loss,with a rate of 2.73‰. Among 180 mutations identified,there were 91 GJB2 mutations（2.26%）,57 SLC26A4 mutations（1.41%）,14 GJB3 mutations （0.35%）,15 mtDNA 12SrRNA mutations （0.37%）and 3 with mutations of two genes （0.07%）. Sixteen mutation sites （184 cases）were found,and the detection rate was 4.57%. Conclusion The rate of carrying deafness genes in Zhoushan newborns was 4.47%. The deafness genes found were mainly GJB2 and SLC26A4,the carrying rate of mtDNA 12SrRNA gene mutation was also high.
