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 .

Objective To investigate the application value of multi-slice CT enterography (MSCTE)in diagnosing intestinal tuberculosis (ITB)and Crohn’s disease (CD).Methods MSCTE findings were retrospectively analyzed in 25 patients with ITB and in other 25 patients with CD diagnosed through endoscopy,pathologic examination and clinical follow-up.Statistical analysis was performed to find out the difference in CT findings between the ITB and CD.Results 25 patients with CD included the involved ileum in 23,involved duode-num and jejunum in 8,multiple segmental lesions in 20,asymmetrically thickened intestinal wall in 20,hierarchical reinforcement in 1 9,mesenteric vascular hyperplasia in 20,fibrofatty hyperplasia in 18,peritoneal abscess or fistula in 8,anal fistula in 1,and pseu-do-diverticulum formation in the intestinal wall on the opposite side of the mesentery in 2.Meanwhile,the other 25 patients with ITB included the involved terminal ileum in 25,symmetrically thickened intestinal wall in 23,annular enhancement of lymph nodes in 11,thickened peritoneum and omentum together with distinct enhancement,or intestinal adhesion,or ascites appeared in 15.The CD was more likely to represent multiple segmental lesions,asymmetrically thickened intestinal wall,hierarchical reinforcement,mesenteric vascular hyperplasia,fibrofatty hyperplasia,and peritoneal abscess or fistula formation (P <0.05).Meanwhile,the ITB was more likely to represent the lesion only in ileum,symmetrically thickened intestinal wall,and annular enhancement of lymph nodes (P <0.05).Conclusion MSCTE shows promising clinical application in diagnosis and differential diagnosis of CD and ITB.

OBJECTIVETo evaluate the clinical effect and safety of dapoxetine in the treatment of premature ejaculation (PE).

METHODSWe randomly assigned 116 PE patients to receive dapoxetine on demand at 30 mg qd (dapoxetine group, n = 60, aged 23-49 years) or oral tamsulosin at 20 mg qd (control group, n = 56, aged 24-46 years). After 4 weeks of medication, we compared the clinical global impression of change (CGIC) , PE profile (PEP) scores, intravaginal ejaculation latency time (IELT) , and adverse reactions between the two groups of patients.

RESULTSCompared with the baseline, the IELT was remarkably prolonged after treatment both in the dapoxetine group ([0.86 ± 0.17] vs [4.32 ± 2.23] min, P < 0.05) and the control ([0.88 ± 0.15] vs [4.17 ± 2.26] min, P < 0.05), with no statistically significant difference between the two groups (P > 0. 05). The post-treatment rate of CGIC in the dapoxetine group had no statistically significant difference from that in the control (85.00% vs 82.14%, P > 0.05). In comparison with pre-treatment, the patients of both the dapoxetine and control groups showed dramatically improved scores after medication in perceived control over ejaculation (0.85 ± 0.23 vs 2.13 ± 0.97 and 0.88 ± 0.21 vs 2.06 ± 0.34, both P < 0.05), ejaculation-related personal distress (1.15 ± 0.64 vs 2.89 ± 0.26 and 1.19 ± 0.53 vs 2.82 ± 0.69, both P < 0.05), satisfaction with sexual intercourse (0.81 ± 0.33 vs 2.58 ± 0.37 and 0.79 ± 0.28 vs 2.45 ± 0.32, both P < 0.05), and ejaculation-related interpersonal difficulty (2.05 ± 0.61 vs 3.24 ± 0.35 and 2.03 ± 0.65 vs 3.18 ± 0.76, both P < 0.05), with no significant differences between the two groups (P > 0.05). The incidence of adverse reactions was significantly lower in the dapoxetine than in the control group (3.33% vs 30.36%, P < 0.05).

CONCLUSIONDapoxetine is effective for the treatment of PE, with its advantages of prolonging the intravaginal ejaculation latency time, improving the quality of sexual life, and low incidence of adverse reactions.

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.

BACKGROUND:Retinal diseases are caused by damage or apoptosis of the retinal cel s and lack of ideal treatment. Induced pluripotent stem cel s have self-renewal ability and differentiation potential. A new potential source from which to produce stem cel s as a therapeutic platform for the treatment of retinal diseases and avoid ethics issues is the research focus currently.
OBJECTIVE:To review recent advancement of induced pluripotent stem cel s and the potential utility for retinal diseases.
METHODS:The first author searched related articles published from 2006 to 2011 by computer retrieval in PubMed database using the keywords of“induced pluripotent stem cel s, retinal, photoreceptor, retinal pigment epithelium, retinal ganglion cel”in English. Final y, total y 42 papers were involved.
RESULTS AND CONCLUSION:Induced pluripotent stem cel s can be induced to differentiate into retinal cel s which have a possibility to be used as donor cel s for transplantation therapies. Patient-derived induced pluripotent stem cel s can be used as disease models for mechanistic studies and drug screening. It is a promising therapy for retinal degenerative diseases. However, some problems stil remain, such as risk of teratoma formation and low efficiency of somatic cel s to be successful y induced into induced pluripotent stem cel s. It stil requires further more studies.
