Objective To explore the roles of macrophage inflammatory protein-1?(MIP-1?)in hypoxic-ischemic encephalopathy(HIE)of newborn infarnts.Methods Serum samples were obtained in 24,72 h and 7 d after birth respectively from 34 newborn infants with HIE,and 20 newborn infants without HIE as control group.Enzyme-linked immunosorbent assay(ELISA)method was used to determine the serum concentrations of MIP-1?.Results Levels of MIP-1? in newborn infants with HIE [(12.47?2.51)ng/L]were significantly higher than that of newborn infants without HIE [(8.63?2.63)ng/L](P0.05).Conclusions MIP-1? are involved in HIE of neonates,and the more severe damage,the higher levels in serum,which suggests that,as an inflammatory mediator,the MIP-1? may play an important role in involvement of brain hypoxic-ischemic damage.

AIM : To construct and analyze eukaryotic expression plasmid inserted by Cx50 with V64G mutation through bioinformatics software.METHODS: The full coding domain sequence of Cx50 with V64G mutation was acquired from the blood of patients with cataract and was cloned into pcDNA3.1 /Amp (+).The constructed plasmid was identified with PCR , enzyme digestion and sequencing. The analysis of Cx50 with V64G mutation was performed with bioinformatics software.RESULTS : Cx50 with V64G mutation was successfully amplified and its eukaryotic expression plasmid was constructed. Valine-64 is well conserved in the first extracellular loop of connexin 50 in different species and also in different human α -type gap junctional proteins.CONCLUSION : The successive reconstruction and verification of eukaryotic expression plasmid containing Cx50 with V64G mutation established the foundation for further studying the mechanism of cataract.

OBJECTIVETo compare the effect of transumbilical single-site single-port with that of transumbilical single-site double-port laparoscopic varicocelectomy in the treatment of varicocele in adolescents.

METHODSWe randomly assigned 80 varicocele patients aged 10 - 16 years to two groups of equal number to receive transumbilical single-site single-port and single-site double-port laparoscopic varicocelectomy, respectively. We compared the operation time, postoperative hospital stay, incisional pain, complications and satisfaction with the abdominal cosmetic outcomes between the two groups.

RESULTSAll the operations were successfully performed. The double-port group showed a significantly higher score on the Visual Analogue Scale than the single-port group (4.8 +/- 1.4 vs 3.6 +/- 1.1, t = -4.986, P < 0.01), but there were no significant differences between the two groups in the operation time ([29.8 +/- 4.2] vs [31.2 +/- 4.6] min, t = 1.383, P = 0.171), postoperative hospital stay ([1.95 +/- 0.7] vs [1.82 +/- 0.8] d, t = -0.784, P = 0.436), complications (0 vs 0) and scores on the satisfaction with abdominal cosmetic outcomes (4.6 +/- 0.6 vs 4.8 +/- 0.5, t = 1.253, P = 0.214). No recurrence, umbilical hernia, hydrocele and orchiatrophy were found in the two groups of patients at 6 months after operation, and no visible scar was observed on the abdominal surface.

CONCLUSIONWith strict surgical indications, single-site single-port and single-site double-port laparoscopic varicocelectomies have similar clinical effects in the treatment of varicocele, which leave no scar on the abdominal surface. Single-site double-port laparoscopy needs no special instruments and therefore is worthier of wide clinical application.

OBJECTIVETo observe the efficacy and safety of acupuncture therapy on moderate and severe allergic rhinitis via the comparison evaluation of western medicine.

METHODSSixty cases of moderate and severe allergic rhinitis were divided into an acupuncture group (30 cases) and a western medicine group (30 cases). In the acupuncture group, the main acupoints included Yingxiang (LI 20), Shangxing (GV 23), Fengchi (GB 20), Quchi (LI 11), Xuehai (SP 10), Feishu (BL 13), Geshu (BL 17), Pishu (BL 20), etc. The supplementary points were selected according to syndrome differentiation. In the western medicine group, budesonide nasal spray and cetirizine tablets were prescribed. All the cases were treated for 8 weeks in the two groups. Separately, before treatment, in 4 weeks and 8 weeks of treatment, the scores of clinical symptoms and physical signs were observed and the clinical efficacy and safety were compared between the two groups.

RESULTSIn 4 weeks and 8 weeks of treatment, the scores of symptoms such as sneezing, nasal discharge, nasal obstruction, nasal itching, eye itching and turbinate hypertrophy, the score of physical signs and total score were all reduced apparently as compared with those before treatment (all P<0. 05). The differences were not significant between the acupuncture group and the western medicine group (all P>0. 05). The total effective rates were 90. 0% (27/30) and 93. 4% (28/30) in the acupuncture group after 4 and 8 weeks of treatment, and were 76. 6% (23/30) and 80. 0% (24/30) in the western medicine group separately, without significant difference in comparison (all P>0. 05).

CONCLUSIONAcupuncture achieves the similar efficacy on moderate and severe allergic rhinitis as western medicine. It is the safe therapy and has no apparent adverse reactions.

The severe fever with thrombocytopenia syndrome virus (SFTSV) is a new member in the genus Phlebovirus of the family Bunyaviridae identified in China. The SFTSV is also the causative pathogen of an emerging infectious disease: severe fever with thrombocytopenia syndrome. Using immunofluorescent staining and confocal microscopy, the intracellular distribution of nucleocapsid protein (NP) in SFTSV-infected THP-1 cells was investigated with serial doses of SFTSV at different times after infection. Transmission electron microscopy was used to observe the ultrafine intracellular structure of SFTSV-infected THP-1 cells at different times after infection. SFTSV NP could form intracellular inclusion bodies in infected THP-1 cells. The association between NP-formed inclusion bodies and virus production was analyzed: the size of the inclusion body formed 3 days after infection was correlated with the viral load in supernatants collected 7 days after infection. These findings suggest that the inclusion bodies formed in SFTSV-infected THP-1 cells could be where the SFTSV uses host-cell proteins and intracellular organelles to produce new viral particles.

Objective To study the effect of the uncertain deflection of the Delta4 phantom (ScandiDos AB,Sweden) in setting up on the Gamma index passing rate during the VMAT plan verification.Methods Two patients with head and neck cancer,two with lung cancers and one with pelvic cancer receiving VMAT radiotherapy were randomly chosen.By means of Eclipse8.6 TPS the treatment plans elaborated for the five patients were picked up to make the verification plans and Delta4 was used to perform dose verification On VARIAN Clinac Ⅸ.The Delta4 phantom was precisely set up first,and then it was deflected in a given angle towards the horizontal direction in relation to the center of the linear accelerator isocenter to perform the dose verification for 11 times successively.To figure out the relationship between the deflection angle of the Delta4 phantom and the Gamma index passing rate.Results As the Delta4 phantom was deflected by 0.0°,0.2°,0.4°,0.6°,0.8°,1.0°,1.2°,1.4°,1.6°,1.8° and 2.0° in sequence,the measured Gamma index passing rates presented a slight decline,but all greater than 90％ (DD 3％,DTA 3 mm).Conclusions In the VMAT plan verification,the Gamma index passing rate of Delta4 has no dependence on the uncertain deflection of the Delta4 phantom provided that the uncertain deflection of the Delta4 phantom is no greater than 2°,but the passing rates of DD and DTA vary significantly with the uncertain deflection of the Delta4 phantom.

Low frequency sensorineural deafness is a common subtype of idiopathic sudden deafness. Certain patients suffered recurrent attacks without vertigo, much alike Meniere's disease. Few of them developed into definite Meniere's disease during long-term follow-up in many clinical studies. Although the pathophysiology of recurrent low frequency deafness is yet unknown, the desease is considered associated with early state of endolymphatic hydrops or migraine. Otologists shall be aware of its clinical course and careful explanation is necessary at time of initial informed consent.

Objective To analyze the therapeutic effect and prognosis of peritoneal dialysis in patients with end-stage polycystic kidney disease.Methods A retrospective analysis was performed on patients with polycystic kidney disease who were treated with peritoneal dialysis for more than 3 months between July 2007 and September 2016 in the Second Hospital Affiliated to Soochow University.A total of 45 patients were enrolled in this study.Another 45 patients of non-diabetic nephropathy were selected as the control group matched by gender,age,and time of PD initiation.The information of the two groups such as general data,dialysis related complications,incidence of peritonitis,prognosis was recorded.Survival analysis was performed using the Kaplan-Meier method and Log-rank test.The risk factors affecting patients' survival were analyzed with Cox regression model.Results There were no significant difference in pre-dialysis age,sex ratio,blood pressure,urine volume,body weight,eGFR,biochemical data,and the proportion of hypertension and diabetes mellitus in the polycystic kidney group and control group.24 h ultra-filtration volume,4 h D/Pcr,Kt/V and Ccr between the two groups showed no significant difference (all P ＞ 0.05).The incidence of peritonitis and the time of the first peritonitis in the two groups respectively as one episode per 82.4 months vs one episode per 81.5 months,(35.8±22.8) months vs (34.5±20.9) months had no statistical difference.The ratio of hernia (6.6％ vs 2.2％),thoracic and abdominal leakage (4.4％ vs 2.2％),dialysate leakage (0 vs 0),catheter dysfunction (4.4％ vs 6.6％),exit-site infections (11.1％ vs 6.6％),tunnel infections (4.4％ vs 2.2％) and non PD related infections (11.1％ vs 13.3％) had no significant difference.The 1-year,3-year,5-year patient survival of two groups respectively were 95.2％ vs 93.3％,78.9％ vs 75.0％,67.6％ vs 64.9％ (P=0.475),and 5-year technique survival was 78.7％ vs 76.7％ (P=0.623),demonstrating no obvious difference.Cox regression analysis showed that age and serum albumin were risk factors for the survival of patients.Conclusions The effect and prognosis of peritoneal dialysis in patients with polyeystic kidney and non polyeystic kidney were similar.Peritoneal dialysis is not the contraindication of polycystic kidney.Peritoneal dialysis can be used as a routine renal replacement therapy in patients with polycystic kidney disease.

OBJECTIVETo examine fractional exhaled nitric oxide (FeNO) values in 1-3-year-old children with asthma and analyze the correlation of FeNO with peripheral blood eosinophils (EOS) and lung function in these children.

METHODSA total of 111 children aged 1-3 years with asthma were enrolled. The children were classified into acute exacerbation (n=62) and remission groups (n=49) according to their symptoms. FeNO values, lung function, and peripheral blood EOS count were measured in these children. Sixty age-matched healthy children were enrolled as the control group.

RESULTSFeNO values were significantly higher in the acute exacerbation group (24.4 ppb) than in the remission group (18.0 ppb) and the control group (13.7 ppb) (P<0.05). The FeNO values in the remission group were significantly higher than in the control group (P<0.05). FeNO values were not significantly correlated with peripheral blood EOS count and lung function parameters (PEF, TEF25, TEF50, and TEF75).

CONCLUSIONSMeasurement of FeNO is useful to evaluate the disease activity in children with asthma aged 1 to 3 years, but the FeNO values are not correlated with peripheral blood EOS count and lung function.

To explore the feasibility of chemical and biological method in evaluation of the in vitro dissolution rate of Liuwei Wuling tablet (LWT), this experiment investigated the inhibitory effect of LWT dissolving solutions on LX-2 hepatic stellate cells in 0.1% SDS dissolution medium in different dissolving periods. From these results, the cumulative dissolution rate of LWT was obtained based on the cell inhibitory rate. The dissolution rates of deoxyschizandrin, phillyrin, and Specnuezhenide were determined by HPLC method. A novel approach of self-defined weighting coefficient had been created to establish the integrated dissolution rate model. Then f2 similar factor method was used to evaluate the relevance of these two methods. The results showed that f2 values for deoxyschizandrin, phillyrin, Specnuezhenide, and the integrated dissolution were 61, 43, 61 and 75 respectively, indicating that the dissolution of multi-component integration could fully reflect the biological potency of the whole recipe. The dissolution evaluation method for multicomponent integration based on biological activity is expected to be one of the effective means for in vitro dissolution test of LWT.
