Objective To study the effect of levels of 24-hour mean blood pressure(BP)and blood pressure diurnal rhythm on renal function of patients with chronic renal failure(CRF).Methods 24-hour blood pressure monitoring was obtained in patients with CRF(117cases),the GFR was determined periodically.Results The rate of decline of GFR in patients with CRF to a target blood pressure was slower than in patients with CRF not to a target BP(P

Objective To investigate the clinical value of neutrophil-to-lymphocyte ratio,platelet-to-lymphocyte ratio and red blood cell distribution width in discriminating disease activity of rheumatoid athritis.Methods Eighty-nine rheumatoid arthritis out-patients of the Affiliated Hospital of Jiangsu University from Jan.2012 to Mar.2013 were recruited into this study.The disease activity index,such as swollen joint count and tender joint count were made by rheumatologists,and laboratory parameters（blood cell analysis,erythrocyte sedimentation rate and C-reactive protein) were measured as well.The enrolled patients were divided into the active RA group and remission RA group based on the DAS28 definition.Differences of NLR,PLR and RDW among groups were analyzed by t test and relations between variables were assessed by Spearman correlation analysis.The t test,non-parametric test and Spearman analysis were used for statistical analysis.Results The levels of NLR (3.2±2.0,2.4±0.9,respectively) and PLR (167±70,133±43,respectively) in active RA group were higher than that of the RA remission group (t=2.28 and 2.50,P=0.02 and 0.01).The level of RDW [(13.9±2.5)％,(13.9±2.4)％,respectively] was not significantly different between the active RA group and the RA remission group (t=0.14,P=0.89).However,compared with healthy controls,the level of RDW [(13.9±2.5)％,(13.2±0.2)％,respectively] was significantly increased in RA patients (t=2.74,P=0.006 9).NLR and PLR were positively correlated with DAS28 (r=0.23,P=0.03;r=0.26,P=0.04,respectively),ESR (r=0.28,P=0.03;r=0.43,P＜0.01,respectively) and CRP (r=0.33,P=0.006;r=0.41,P＜0.01,respectively).However,there was no association between RDW and DAS28 (r=0.01,P=0.93),ESR (r=0.20,P=0.15) and CRP (r=0.05,P=0.71).Areas under curve of receiver operating characteristic (ROC) for assessing disease activity of rheumatoid athritis by NLR and PLR were 0.802 and 0.753 respectively.The cut-off values for discriminating active/remission RA were 2.86 and 143.05,with the sensitivity as 0.66 and 0.63,specificity as 0.72 and 0.65.Conclusion NLR and PLR are significantly associated with the disease activity of RA and can be useful to understand the activity state of the illness.

Objective To discuss the effect of DNA extraction of bloodstain on the filter paper with four methods of solid phase absorption.Methods 180 bloodstain samples on the iflter paper, each one contains 1 microlitre anticoagulation peripheral venous blood, divided into 4 groups with 45 samples, respectively. All samples were treated with four methods of solid phase absorption, i.e. DNA IQ? System, D-shield sensitive DNA Extraction Kit, High efficiency Silica Bead DNA Extraction Kit and Conventional silica bead method. The concentration of DNA and the results of STR typing of four groups were compared each other.Results The concentration of DNA was 3.764±1.790μg/mL and 3.634±1.112μg/mL by using D-shield sensitive DNA Extraction Kit and High efifciency Silica Bead DNA Extraction Kit, respectively. However, the concentration of DNA by using Conventional silica bead method group (3.350±1.250) was not signiifcantly different from each other (P<0.05), while the concentration of DNA extracted with above three methods were higher than by using DNA IQ? System (1.864±1.207)(P<0.001); Signiifcant differences of peak height existed between DNA IQ? System and other three methods (P<0.001); As the same time, the peak height of samples by using High efficiency Silica Bead DNA Extraction Kit and Conventional silica bead method were signiifcantly different from D-shield sensitive DNA Extraction Kit (P<0.01).Conclusions The DNA extracted in bloodstain on the iflter paper by using D-shield sensitive DNA Extraction Kit, High efifciency Silica Bead DNA Extraction Kit and Conventional silica bead method was more than DNA IQ? System. Meanwhile, the quality of DNA using High efifciency Silica Bead DNA Extraction Kit and Conventional silica bead method may be higher.

This study was aimed to evaluate impacts on immune regulation with spleen-strengthening and kidney-tonifying method among advanced malignant tumor patients. The enrolled advanced malignant tumor patients were randomly divided into the control group and the treatment group. The control group was treated with conventional treatment plan. The treatment group was treated with spleen-strengthening and kidney-tonifying Chinese herbs on the basis of conventional treatment plan for three months. Clinical effect, integral of clinical symptom (ICS), T-lym-phocyte subsets, and drug safety index were observed and detected before and after treatment. The results showed that the effective rate and response rate in the control group were 31.1% and 71.1%, respectively. And the effective rate and response rate in the treatment group were 54.2% and 85.4%, respectively. The treatment group was better than the control group (P< 0.05). Compared to the control group, the treatment group had obvious regulation on T-lymphocyte subsets. The improvement on ICS in the treatment group was better than the control group (P < 0.05). There was no obvious adverse reaction with the application of Chinese herbs. It was concluded that the spleen-strengthening and kidney-tonifying method can improve clinical effect, life of quality, and reduce adverse reaction a-mong advanced malignant tumor patients. Its mechanism may be through the regulation of immune function.

Objective To investigate the effective regimen to treat the hepatitis C virus (HCV) recurrence after orthotopic liver transplantation (OLT). Methods The clinical data of 4 cases of HCV recurrence after OLT were retrospectively analyzed. Of the 4 cases, there were 3 cases of HCV related liver cirrhosis and 1 case of HCV related liver cirrhosis in combination with hepatocellular carcinoma. The immunosuppression regimen as FK506, MMF and corticosteroids was used after OLT. As soon as HCV recurrence was confirmed by liver biopsy during 8 to 12 weeks after OLT, pegylated interferonα-2a (PEG-IFNα-2a) and ribavirin (RIB) were used for 48 weeks. PEG-IFNα-2a was started at a dose of 180 μg per week subcutaneously and RIB at a dose of 1000 mg per day orally, respective-ly. Blood routine, liver and kidney function test, HCV-RNA and transplanted liver biopsy were per-formed when necessary and biochemical response, sustained virologic response and histological re-sponse were tested in due time. Remits All of the 4 cases except for 1 achieved sustained virologic re-sponse and the liver function was as normal as before. The histological activity index was improved significantly for both inflammatory activity and fibrosis according to liver biopsy in 0, 48, 72 week srespectively. Case 4 was given corticosteroids for consecutively 3 days when acute rejection was veri-fied by liver biopsy and the condition improved. None of them stopped treatment or withdrew from them directly. Conclusion The combination of PEG-IFNα-2a and RIB was an effective regimen to treat the HCV recurrence after OLT and the side effects could be overcame easily.

Objective To investigate the relationship between rapists and related allele genes based on the analysis of 15 short tandem repeats (STRs) loci genetic polymorphism. Methods The method of Genome-wide scan was being used. Buccal swab samples of 129 rapists and 156 random populations were collected and PCR compound amplification was carried out with the aid of AmpFISTR Identifiler system. Then the products were subjected to electrophoresis and gene detection with AB13100 type gene analysis system so as to calculate and compare the alleles of 15 STRs gene frequency in the two groups. Results All the 15 STRs loci allele gene frequency in rapists and random population was found to coincide with Hardy-Weinberg law(P>0. 05). Allele 28 of D21S11 (rapists: 1.55% ,control group:5. 13%) ,allele22 of FGA(rapists:24.03% ,control group:16.99%),allele23 of FGA(rapists: 17.05% ,control group:26.28%) ,allele 10 of TH01(rapists:1.16% ,control group:4.17%) ,allele 8 of TPOX(rapists:55.77% ,control group:63.77%),allele 12 of TPOX(rapists:4.26% ,control group: 1.28%) were different between the two groups (P< 0.05) .while it is no differ significantly in other STRs loci allele gene(P >0.05). Conclusion Allele 28 of D21 S11,allele 22 and 23 of FGA, allele 10 of TH01, allele 8 and 12 of TPOX may be associated with the violent crime of rape. It is suggested that there are existing sensitive or resistance genes about the violent crime of rape in chromosome 2,4,11,21.

Objective To evaluate the effects of ulinastatin on hemorrhagic shock and resuscitation ( HS∕R)?induced acute lung injury in rats. Methods Fifteen SPF adult Sprague?Dawley rats, aged 2-3 months, weighing 300-400 g, were divided into 3 groups ( n=5 each) using a random number table:sham operation group ( group S ) , HS∕R group and ulinastatin group ( group U ) . Carotid arteries were cannulated for blood pressure monitoring and blood?letting. HS∕R was induced by blood?letting and maintained for 1 h, followed by resuscitation with autologous blood transfusion and infusion of normal saline. After cannulation of carotid arteries ( T0 ) , at 5 min after hemorrhagic shock ( T1 ) , before resuscitation ( T2 ) , at 5 min after the expected blood pressure was achieved following resuscitation ( T3 ) , and at 30 min, 1?5 h and 2?5 h after resuscitation ( T4?6 ) , arterial blood samples were collected for determination of interleukin?6 ( IL?6 ) and tumor necrosis factor?α ( TNF?α) concentrations ( by enzyme?linked immunosorbent assay) . Arterial blood samples were collected at T0 , T2 and T6 for blood gas analysis. The pH value, partial pressure of arterial carbon dioxide ( PaCO2 ) , HCO-3 and base excess ( BE) value were recorded, and oxygenation index ( PaO2∕FiO2 ) was calculated. Lungs were removed at T6 , and pulmonary specimens were obtained for examination of pathological changes which were scored, and nucleus was extracted for determination of nuclear factor?kappa B ( NF?κB ) p65 expression by enzyme?linked immunosorbent assay. Results Compared with group S, the pH values, HCO-3 , BE values and OI were significantly decreased, and PaCO2 , plasma IL?6 and TNF?α concentrations, expression of NF?κB p65 in lung tissues, and pathological scores were increased in U and HS∕R groups. Compared with group HS∕R, the plasma concentrations of IL?6 and TNF?α, expression of NF?κB p65 in lung tissues, and pathological scores were significantly decreased, and no significant changes were found in parameters of blood gas analysis in group U. Conclusion Although ulinastatin can alleviate HS∕R?induced acute lung injury, it is insufficient to improve lung oxygenation in rats.

The effect of initial substrate concentration on the growth,metabolic activities of Photosynthetic bacteria (PSB) in the process of hydrogen production is studied.The empirical relation of the initial substrate concentration to the specific growth rate,specific substrate consumption rate and specific hydrogen production rate of PSB are developed based on the modified Monod model.It is found that the results given by the model are well agreed with the experimental data in growth phase and stationary phase of PSB.Meanwhile,the optimal substrate concentration in the process of growth,metabolism and hydrogen production is 50 mmol/L.Furthermore,when the initial substrate concentration deviates 50 mmol/L,the activation of PSB is limited or inhibited,and the inhibiting effect is more prominent than the limiting effect.In addition,it is demonstrated that initial substrate concentration has little effect on the specific substrate consumption rate.

Objective To explore the effects of skill-training on social function in patients with schizophrenia recession. Methods 60 patientswith schizophrenia recession were divided into 2 equal groups (n=30) for 1-year treatment. The control group was treated only withdrugs, and the treatment group was treated with skill-training in addition. The patients were assessed with the Scale of Social Skill of ChronicSchizophrenic Inpatients (SSSI) and the Positive and Negative Symptom Scale (PANSS) before, 6 months and 12 months after treatment.Results The total scores of PANSS decreased significantly in the treatment group compared with the control group (P<0.01). The scores ofSSSI decreased significantly in the treatment group after treatment. However, there was no significant differences in the control group (P>0.05) 6 months after treatment, but was 12 months after treatment (P<0.05). Conclusion Based on the medicine treatment, skill-training mayimprove the flinched mental symptom to remain the social function.

Objective: To understand the behavioral characteristics of vaccination of human papillomavirus (HPV) vaccine based on diffusion of innovation theory, and to put forward suggestions for improving the vaccination willingness. Methods: The women who had made an appointment or received at least one dose of HPV vaccine in two community health service centers with HPV vaccination qualification in Hangzhou were recruited by convenience sampling method. A questionnaire survey was conducted according to cervical cancer risk factors, HPV vaccine knowledge and the time of vaccination. The diffusion of HPV vaccination and the characteristics of vaccinees in different stages was analyzed. Results: A total of 448 women, aged from 18 to 45 years old, with a median of 30.5 years old, were investigated. The spread of HPV vaccine were divided into five stages: April 2017 and before was the initial stage, with 8 leaders, accounting for 1.79%; October 2017 to February 2018 was the slowly rising stage, with 59 early vaccinees, accounting for 13.17%; April 2018 to April 2019 was the rising stage, with 160 most early vaccinees, accounting for 35.71%; May to August 2019 was the rapidly rising stage, with 170 most late vaccinees, accounting for 37.95%; September 2019 to the end of the survey was the standstill stage, with 51 laggards, accounting for 11.38%. All of the leaders had participated in cervical cancer screening, voluntarily vaccinated, and knew the susceptible population of cervical cancer, the targeted HPV types and the suitable population of vaccine. The median age of the first pregnancy was 27 years old. Six of them had three pregnancies. The early vaccinees and the most early vaccinees were recommended by doctors or friends to get HPV vaccine. The median age of first pregnancy was 26 and 28 years old, respectively. Their other characteristics were similar to those of the leaders. The characteristics of most late vaccinees were similar to those of the laggards. They were were mainly students who were recommended by their friends to receive HPV vaccination, did not participate in cervical cancer screening, did not know the susceptible population of cervical cancer, the targeted HPV types and the suitable population of vaccine. Conclusions People with high risk of HPV exposure, awareness of cervical cancer and screening are more likely to receive HPV vaccination at the early stage. It is necessary to strengthen the health education of HPV vaccination, and make full use of the influence of doctors and early vaccinees, which is helpful to promote the early vaccination of HPV vaccine among the right age population.
