Objective To observe the therapeutic effect of Gegen Decoction plus Sini Powder for polycystic ovarian syndrome(PCOS) women with acne and to explore its possible therapeutic mechanism.Methods Seventy cases of PCOS women with acne aged 18-45 years were randomized into treatment group and control group,35 cases in each group.The treatment group was given Gegen Decoction plus Sini Powder orally and the control group was given Diane-35 orally.The treatment lasted for 12 weeks.After treatment,the skin lesions and symptom scores were observed.The body mass index (BMI),serum dihydrotestosterone (DHT),interleukin-6 (IL-6) and interleukin-8 (IL-8) were detected before and after treatment.Results (1) The markedly effective rate of the treatment group was 80.00％ and that of the control group was 57.14％,the difference being significant between the two groups(P ＜ 0.05).(2) After treatment,the total scores of the symptoms and the scores of each symptom such as sweating,sleeping and physical strength in both groups were decreased(P ＜ 0.01),and the decrease in the treatment group was superior to that in the control group(P ＜ 0.05).(3) The BMI and serum levels of DHT,IL-6 and IL-8 in both groups were significantly decreased after treatment (P ＜ 0.01),and the decrease in the treatment group was superior to that in the control group(P ＜ 0.05).Conclusion Gegen Decoction plus Sini Powder is effective for the treatment of PCOS women with acne,and the mechanism is probably related with the decrease of BMI and serum DHT,IL-6 and IL-8 levels.

Objective To evaluate the value of bedside index for severity in acute pancreatitis (BISAP) in predicting the severity and prognosis of acute pancreatitis (AP) by comparison with traditional scoring systems.MethodsFour hundred ninety-seven patients of AP admitted into Wuxi People's Hospital from January 2005 to December 2010 were studied retrospectively.BISAP,APACHE Ⅱ,Ranson and Balthazar CT (CTSI) scores were calculated,respectively,in order to evaluate the severity.The AUC of ROC was used to evaluate the ability of BISAP and the other scoring systems in predicting the severity of AP and the occurrence of pancreatic necrosis,organ failure and mortality.Results Among 497 patients,mild acute pancreatitis (MAP) was identified in 396 patients and severe acute pancreatitis (SAP) in 101 patients.The gender,age and etiological factors between MAP and SAP were not statistical different.The BISAP,APACHE Ⅱ,Ranson scores of the 4 9 7 patients were 1.08 ± 1.01,5.79 ± 4.00,1.69 ± 1.59,and the scores were intercorrelated(r =0.612,0.568,0.577,P ＜0.001).In addition,the BISAP,APACHE Ⅱ,Ranson scores of SAP patients were significantly higher than those in MAP patients.The AUC of BISAP for SAP was 0.762(95％ CI 0.722 ～0.799),when the cutoff value was 2,the sensitivity,specificity,positive predictive value (PPV),negative predictive value ( NPV ) were 63.39％,83.08％,48.1％,89.4％ ; the AUC of BISAP for pancreatic necrosis was 0.711 (95％ CI 0.612 ～ 0.797),when the cutoff value was 2,the sensitivity,specificity,PPV,NPV were 84.6％,46.7％,35.5％,89.7％ ; the AUC of BISAP for organ failure was 0.777( 95％ CI0.683 ～ 0.854),when the cutoff value was 2,the sensitivity,specificity,PPV,NPV were 93.1％,51.4％,43.5％,94.9％ ; the AUC of BISAP for mortality was 0.808(95％ CI 0.718 ～0.880),when the cutoff value was 3,the sensitivity,specificity,PPV,NPV were 83.3％,67.4％,25.6％,96.8％.In the cases of SAP,the ability of BISAP and the other scoring systems in predicting the prognosis showed no statistical difference.ConclusionsThe BISAP has the prediction ability for AP severity and prognosis similar to other scoring systems,and it consists of only 5 parameters and can be completed in the fast 24 h of admission,therefore it can be used for early predication of SAP,which is worth of clinical application.

Objective To investigate 4 variants single nucleotide polymorphisms (SNPs) of 5-lipoxygenase-activating protein(ALOX5AP) in lipoxygenase pathway and in cytochrome P450 pathway as susceptibility genes for stroke in a southeastern Chinese population,and evaluate the associations between susceptibility genes and cerebral infarction,to find whether gene-gene interactions increase the risk of cerebral infarction.Methods By case-control study,two hundred and ninety-two patients with cerebral infarction and 259 healthy control subjects were included.Eight variants in 5 candidate genes were examined for stroke risk,including the SG13S32 (rs9551963),SG13S42 (rs4769060),SG13S89 (rs4769874),and SG13Sl14 (rs10507391) variants of the ALOX5AP gene,the G860A (rs751141) variant of the soluble epoxide hydrolase (EPHX2) gene,the A1075C (rs1057910) variant of the CYP2C9 *2 gene,the C430T (rs1799853) variant of the CYP2C9* 3 gene,and the A6986G (rs776746) variant of the CYP3A5 gene.Gene-gene interactions were explored using generalized multifactor dimensionality reduction (GMDR)methods.Results There were no statistically significant differences in the frequencies of the genotypes of the 8 candidate genes.The GMDR analysis showed a significant gene-gene interaction between SG13S114 and A6986G,with scores of 10 for cross-validation consistency and 9 for the sign test (P =0.011).These genegene interactions predicted a significantly higher risk of cerebral infarction (adjusted for age,hypertension,and diabetes mellitus;OR =1.804,95％ CI 1.180-2.759,P =0.006).Conclusions A two-loci gene interaction confers significantly higher risk for cerebral infarction.The combinational analysis used in this study may be helpful in the elucidation of genetic risk factors for common and complex diseases.

Objective To compare the effects of peripherally inserted central catheter(PICC)and venous port access (VPA)on the complication incidence of breast cancer.Methods A total of 191 breast cancer patients with VPA and 218 ones with PICC for chemotherapy from January 2012 to January 2014 were involved.The two groups were compared in respect of incidence of complications during intubation.Result The complication incidence in the VPA group was lower than the PICC group(P<0.05). Conclusion VPA is an ideal pathway for intravenous infusion in breast cancer patients undergoing chemotherapy.

Objective To investigate the interrelations of ALOX5AP SG13S114A/T , COX-2 765G/C , COX-1-50C/T polymorphisms and cerebral infarction. Methods The ALOX5AP SG13S114A/T, COX-2 765G/C and COX-1 50C/T polymorphisms in 411 cases with cerebral infarction and 411 controls were measured by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism method. The generalized multifactor dimensionality reduction (GMDR) method was employed to detect gene-gene interactions. Results Single-gene analysis showed that there were no significant differences in the genotype and allele frequency distributions of ALOX5AP SG13S114A/T, COX-2 765G/C and COX-1 50C/T between two groups. However, in those cases carrying ALOX5AP SG13S114AA as well as COX-2 765CC , the risk of cerebral infarction increased significantly by 2.842 times. Conclusions The combinational analysis among genes used in this study may be helpful in the elucidation of genetic risk factors for common and complex diseases.

Objective To investigate the clinical features of glucose transporter 1 deficiency syndrome(GLUT1-DS) and summarize the characteristics of GLUT1-DS through reviewing related references.Methods The clinical data including manifestation,cerebrospinal fluid (CSF) glucose,electroencephalogram,MRI and gene mutation of a patient with GLUT1-DS was collected and the related literatures were reviewed.Results The patient was a 6 years old boy.The patient,whose seizures occurred at the age of 9 month-old and prolonged to 6 year-old,attacked before breakfast.Physical examination showed microcephaly with head circumference 47.5 cm.Laboratory tests showed that CSF glucose decreased (1.87 mmol/L) and CSF-serum ratio was 0.36.And meantime the MRI was normal and electroencephalogram showed general spike and slow wave complex paroxysm.Mutation of SLC2A1 gene,c.350_385del,was found in the patient.There were 219 cases with GLUT1-DS had been reported and the age of onset was 15.69 months.In 219 patients,159 cases (72％) suffered seizures,105 cases (47％) had motor abnormalities,61 cases (27％) suffered intellectual disability.The CSF glucose values were (1.92±0.31) mmol/L,CSF-serum ratio was 0.36±0.07.SLC2A1 gene mutations were detected in 183 patients(96％)in which missense mutation was the most mutation.Conclusion A wide range of phenotypes of GLUT1-DS include seizures,motor abnormalities,mental retardation.The diagnosis is confirmed when CSF glucose and CSF-serum ratio are continuously decreased which in the absence of meningitis.The SLC2A1 gene should be detected in suspicion of GLUTI-DS patients.Early diagnosis and treatment may improve the prognosis of those GLUTI-DS patients.

Objective To explore the effect and its clinical significance of different dose of glucocorticoids on inflammation mediators in patients with acute exacerbation of chronic obstructive pulmonary diseases.Methods 45 patients admitted to our hospitals from March 2007 to March 2011 were randomly divided into 3 groups:methylprednisolone 40 mg group (methylprednisolone 40mg,iv,qd),methylprednisolone 80 mg group (methylprednisolone 80mg,iv,bid),and control group (without any glucocorticoids).The changes of dyspnea scores,arterial blood gas analysis,clinical symptom scores and serum IL-6,IL-8 and tumor necrosis factor (TNF) levels were detected in patients of each group before and at the 7th day after treatment.The related adverse drug reactions were recorded.Results The improvements in clinical symptom scores,Borg scores,PaCO2,PaO2 after treatment were higher in methylprednisolone 40 mg group and methylprednisolone 80 mg group than in control group (F=3.6747.162 and 42.88,respectively,P＜0.01 or 0.001),and the above improvements was better in methylprednisolone 80 mg group than in methylprednisolone 40 mg group (all P＜0.05).The decreases in levels of serum IL-8,TNF-α,IL-6,C-RP after the treatment were more significant in methylprednisolone 40 mg group and methylprednisolone 80 mg group than in control group (F=12.65,16.17,30.99,respectively,all P＜0.001),and the decrements were more significant in methylprednisolone 80 mg group than in methylprednisolone 40 mg group(all P＜0.05).NO serious adverse drug reactions happened during the course of treatment in the three groups.Conelusions Short-term and moderate dose of glucocorticoid treatment is effective and safe in treating the patients with acute exacerbation of chronic obstructive pulmonary diseases.Methylprednisolone 80 mg injection daily can more obviously improve AECOPD symptoms,and reduce the levels of inflammatory factors better.

[ ABSTRACT] AIM:To investigate the effect of hydrogen sulfide ( H2 S) on airway inflammation induced by ozone (O3) exposure and its mechanisms.METHODS:C57BL/6 mice (n=32) were randomly divided into control group, O3 group, NaHS+O3 group and NaHS group.The mice in O3 group and O3 +NaHS group were exposed to 2.14 mg/m3 O3 for 3 h on days 1, 3 and 5, while the mice in control group and NaHS group were exposed to filtered air .NaHS (14μmol/kg) was administered intraperitoneally to the mice in NaHS group and O 3 +NaHS group 30 min before each exposure .After the last exposure for 24 h, the airway responsiveness was determined , and bronchoalveolar lavage fluid ( BALF) was collected for counting inflammatory cells and measuring total protein concentration .The lung tissues were collected for observing the morphological changes with HE staining .The levels of interleukin-6 ( IL-6 ) , interleukin-8 ( IL-8 ) , malondialdehyde ( MDA) and NF-κB p65 protein in the lungs were determined .RESULTS: Compared with control group , the airway re-sponsiveness, inflammatory cells, protein concentration, inflammation score, levels of IL-6, IL-8, MDA and NF-κB p65 in O3 group increased significantly , but these in NaHS+O3 group decreased compared with O 3 group.CONCLUSION: The present findings suggest that H 2 S attenuates O3 induced airway inflammation by inhibiting NF-κB expression and preventing lipid peroxidation .

ObjectiveThe clinical features, bacteria distribution and antibiotic resistance proifle of blood stream infection(BSI) were investigated in the patients with decompensated liver cirrhosis for better management of such infections.MethodsThe clinical data of BSI were collected in the patients with decompensated liver cirrhosis between January, 2012 and December, 2014, and reviewed retrospectively in terms of risk factors, diagnosis and treatment, pathogen distribution and prognosis.ResultsOf the 1 071 patients with decompensated liver cirrhosis and suspected bacterial infection, 154 (14.4%) were diagnosed as BSI evidenced by blood culture. Of these patients, the leukocyte count in the peripheral blood was higher than 10×109/L in only 48 (31.2%) patients; neutrophil proportion>0.75 in 133 patients (86.4%); serum procalcitonin level>0.5 ng/mL in 74 patients (68.5%). A total of 155 bacterial strains were isolated, including 115 strains of gram-negative bacilli and 40 strains of gram-positive cocci. Most patients (68.8%) recovered and 31.2% died or discharged from hospital voluntarily. All these BSI patients had Child-Pugh grade C liver function. Some patients also had other serious systemic diseases or repeated hospitalization.ConclusionThe prevalence of BSI is high in the decompensated liver cirrhosis patients with poor prognosis. Gram-negative bacilli are the major pathogens of such septicemia. Early diagnosis and proper use of antibiotics based on antimicrobial susceptibility testing are important to improve patient outcome.
