ObjectiveTo study the clinical characteristics of the temperature instability in Prader-Willi syndrome (PWS). MethodsThe clinical characteristics of one case of PWS with recurrent fever were retrospectively analyzed.ResultsA 5-month-old boy who had such clinical characteristics as low central muscle tension, sucking weakness, feeding dififculties, cryptorchidism and white skin was diagnosed as PWS by chromosomal microarray analysis and methylation-speciifc PCR. In the course of the disease, the infant presented recurrent fever. The pathogenic bacteria culture and virus antibody detection showed negative, and the treatment of reducing fever, anti-infection and immune support were ineffective.ConclusionsThe cause of the recurrent fever is unknown and central fever is suspected. Whether the temperature instability is the clinical feature of PWS still needs a lot of clinical researches.

We carried out parallel design and development of two differently structured auto sampler based on a multi-axis and multi-mode high-precision closed-loop servo control system. An integrated embedded control drive module was developed based on the idea of compatibility and inter-changeability, so that DC motor and encoder were standardized into uniform models. Meanwhile, electric and mechanical interfaces were uniformed to a same standard. This allows the direct exchange of above-mentioned components between the two models. A 1-μL manual sample injection syringe was installed on both standard 110-sample and platform 40-sample liquid auto sample injectors connected with gas chromatographer. Approximately 0. 5μL of cetane-isooctyl was sampled for 6 consecutive times at six different positions in the sample bottle. The repeatability RSDs of the injection peak areas of the two systems were 1. 1% and 1. 5%, respectively. A linear correlation coefficient (0. 9947) of peak area with injection volume was achieved based on the gradient sampling volume of 0. 1, 0. 3, 0. 5, 0. 7 and 0. 9 μL.

Objective To summarize the experience in diagnosis and treatment of popliteal vein entrapment syndrome (PVES). Methods A total of 57 patients with PVES were selected from the Department of Vascular Surgery in Xinxiang Central Hospital from March 2009 to October 2015. Of which 43 patients were severe stenosis of popliteal vein (stenosis degree>90%), and another 14 cases were with stenosis less than 90%. All the patients underwent ascending venography of low limb to confirm the clinical classification after admission. Forty-three cases with severe stenosis of the popliteal vein were treated with releasing popliteal vein of entrapment and stripping varicose veins. The static pressure and dynamic pressure of popliteal vein and foot dorsal vein were measured before and after operation. Another 14 patients were treated with medical circulation driven sock and medical therapy. Results The degrees of popliteal vein stenosis were more than 75% in all patients. The patients were divided into bove-knee stenosis (n=9), knee stenosis (n=18), and below-knee stenosis (n=30) according to the different parts of stenosis. Forty-three patients treated with surgery showed relief of leg swelling and pain, and ulcer healing. And the imaging examination showed that there were no obvious compression and stenosis of popliteal vein, and vascular filling was well. The static pressure and dynamic pressure of the popliteal vein and dorsal vein were lower than those before surgery (P<0.05). The lower limb swelling and pain were relieved, and varicose veins of lower limbs were no longer continued to increase in 14 patients with conservative treatment. Conclusion PVES is easy to be misdiagnosed, which should be paid attention to, and satisfactory clinical results can be achieved by releasing popliteal vein of compression combined with stripping varicose veins in patients with serious symptoms .

Transforming growth factor-?_1 (TGF-?_) mRNA or protein expression in renal cortex of diabetic rats was assessed by real-time quantitative RT-PCR with SYBR Green,immunohistochemistry or Western blot.After melatonin treatment,the expressions of TGF-?_1 mRNA and protein were decreased,suggesting that beneficial effect of melatonin may result from its antioxidative property and inhibiting TGF-?_1 expressions.

Objective To estimate the life expectancy of persons with physical disabilities in China based on data related to representative national disability.Methods Life table technique was used to estimate the life expectancy and its standard error by various characteristics on the basis of average mortality rates from the monitoring cases during 2007-2010.Results (1)Females were expected to live longer than males.The life expectancy at birth for females was 63 years with standard error(SE)=2.6 while for males it was 55 years(SE=3.1).(2)Persons aged 35-50 in urban areas had higher life expectancy than those in rural areas.(3)Life expectancy of persons with mild disability [62.5 years(SE=2.4)] was higher than that of persons with severe disability[42 years(SE=5.4)].(4)Life expectancies of persons with physical disability were much lower than that of the Chinese general population.Gaps of male and female life expectancy at birth were 17.1 years and 12.7 years,respectively.Conclusion Persons with physical disability had higher mortality and actions should be taken to improve their life expectancy,accordingly.

Objective To investigate the possibility of detection of the human papillomavirus (HPV)L1 capsid protein to predict the coarse of mild or moderate cervical intraepithelial neoplasia(CIN).Methods Immunocytochemical analysis using antibody against HPV L1 capsid protein was carried out on 274 samples obtained from women performed Tri Path Pap tests.positive for high-risk HPV DNA detected by hybrid capture Ⅱ (HC-Ⅱ)or cytologic diagnosed atypical squamous cells of undetermined significance (ASCUS)or more severe.For cytological diagnosed,there were ASCUS 105 cases,low-grade squamous intraepithelial lesions (LSIL) 119 cases,atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H)9 cases,high-grade squamous intraepithelial lesions(HSIL)36 cases,and squamous cell carcinoma(SCC)5 cases.But for the pathologic diagnosed,there were chronic cervicitis 96 cases.CIN Ⅰ 55 cases,CIN Ⅱ 55 cases,CIN Ⅲ 32 cases,and SCC 6 cases.Results Of the 274 cases,HPV L1 capsid protein was positive in 69.8%(67/96) of cervicitis,83.5%(71/85)of CIN Ⅰ,41.8% (23/55)of CIN Ⅱ,3.1%(1/32)of CIN Ⅲ and 0(0/6)of SCC.Cytologic diagnosis revealed a higher expression rate in LSIL(75.6%.90/119) than that in ASCUS(63.8%,67/105)or in HSIL + SCC (9.8%,4/41;all P<0.01).Of 71 cases with ASCUS and ISIL without treated,none of HPV L1 positive cases(0/55)progressed in cytology,while 19%(3/16)of HPV L1 negative cases progressed to ASC-H,HSIL(P<0.01).Conclusion The expression rates of HPV L1 protein in liquid-based cell specimen is decreased as the cytopathology diagnosis severe degree.which may imply the histopathology diagnosis of cervix,predict the progression of cervical lesion,and help to treat the cases with ASCUS and LSIL.

Objective To investigate the clinical characteristics and mutations of guanosine triphosphate eyclohydrolase (GCH) Ⅰ gene in patients with dopa-responsive dystonia (DRD). Methods Five families with 18 affected family members and 17 patients with sporadic DRD were examined. Patients were allocated into 3 groups according to onset time, either in childhood, or in adolescence or adult. Interview, physical examination, psychologic testings and CT/MR scan were performed. Mutation screening was performed on 26 patients and 1 normal family nember. Thirty-five healthy control subjects were matched for age and sex. Statistical analysis were conducted with the use of SPSS 13.0 computer software. Results(1)Most of patients started with dystonia. The main clinical manifestation was dystonia too. There was no difference among 3 groups.(2) There were significant differences in diurnal fluctuation among 3 groups(15/15,6/6,7/14, χ2=13.125,P=0.001). Diurnal fluctuation negatively correlated with age (r=-0.720, P<0.01).(3)The differences in postural tremor were also found among 3 groups (7/15,5/6,1/14, χ2=8.073, P=0.018). Postural tremor positively correlated with age (r=0.399, P=0.018).(4)There were differences in exaggeration of tendon among three groups(11/15,1/6,4/14, χ2=8.309, P=0.016). Exaggeration of tendon reflexes negatively correlated with age (r=-0.429, P=0.010).(5)The scores of Hamilton Depression Scale and Hamilton Anxiety Scale in patients were higher than those in controls.(6)DNA sequencing revealed a heterozygous A224G missense mutation(Tyr75Cys)located within exon 1 in one autosomal dominant inheritance family. Conclusions The manifestations of DRD varies. The clinical course is closely correlated with age. A missense mutation(A224G)in coding region of the GCH 1 gene probablyleads to the occurrence of DRD.
