Objective Explore the feasibility of minute cells STR typing.Methods Minute cells which were obtained by micromanipulation method were amplified with MiniFiler kit,and detected by ABI 3130 genetic analyzer.Results Ten cells can be successfully genotyped.Complete genotyping results can be obtained for one,three or five cells but with stochastic effect.Conclusion Instability is observed in minute cells genotyping,so it can not be used in actual case work.Maybe increase the quantity of DNA template can improve the success rate.

Sphingosine kinase 1 (SphK1) plays critical roles in cell biological functions. Here we investigated the effects of SphK1 inhibitor SKI II on hepatoma HepG2 cell cycle progression and invasion. Cell survival was determined by SRB assay, cell cycle progression was assayed by flow cytometry, the ability of cell invasion was measured by Matrigel-Transwell assay and protein expression was detected by Western blotting. The results showed that SKI II markedly inhibited HepG2 cell survival in a dose-dependent manner, induced G1 phase arrest in HepG2 cell and inhibited cell invasion. SKI II markedly decreased the expressions of G1-phase-related proteins CDK2, CDK4 and Cdc2 and the levels of cell invasion-associated proteins MMP2 and MMP9. The results showed that SKI II inhibited cell cycle progression and cell invasion, implying SphK1 as a potential target for hepatoma treatment.

Objective To discuss the effect of comprehensive mental intervention on mental health and sleep quality among the crew members during the Escort Mission in the Gulf of Aden.Methods The same batch of two escort ships was divided into study group and control group.The study group was intervened by comprehensive psychological intervention methods involving diversified forms of psychological training, counseling, behavioral intervention and cooperation between various departments.A psychological survey was conducted with Symptom Checklist 90( SCL-90) , Self-rating Anxiety Scale (SAS), Self-rating Depression Scale(SDS) and Pittsburgh Sleep Scale(PSQI) before and 3 months after intervention. Results There was no significant difference between the two groups before intervention (P>0.05).After intervention,the score of SCL-90 of study group was significantly better than that of the control group in somatization,obsessive compulsive disorder,interpersonal relationship,depression, anxiety,bigotry and hostility (P<0.05), while the score of SAS and SDS was lower(P <0.05).Sleep quality, the time taken to fall asleep, sleep time, dyssomnia,sleep efficiency,daytime dysfunction factor and the total score of PSQI were significantly more desirable than in control group (P<0.01).Conclu-sion Comprehensive intervention can effectively improve mental health and sleep quality of the crew members in the escort mission in the Gulf of Aden.It is worthy of popularization and application.

Objective To investigate the change of indications of emergency obstetric hysterectomy and the clinical application of intraoperative interventions. And to provide evidence for prevention of hysterectomy and improvement of obstetric quality. Methods Clinical data were collected from 97 patients who received emergency obstetric hysterectomy at Shengjing Hospital of China Medical University between January 1st, 2004 and December 31st, 2013. The patients were divided into two groups by the time point of January 1st, 2009: the first group was cases treated between January 1st, 2004 and December 31st, 2008, while the second group was cases treated between January 1st, 2009 and December 31st, 2013. The clinical indicators, surgical indications, intraoperative interventions, and blood loss between the two groups were analyzed retrospectively. Results (1) Incidence:54 857 women delivered at Shengjing Hospital of China Medical University between January 1st, 2004 and December 31st, 2013. Of them, 97 patients received emergency obstetric hysterectomy, with an incidence of 0.177% (97/54 857). (2) The 17 patients delivered vaginally (18%,17/97) and 80 by caesarean section (83%,80/97). Forty-nine patients experienced repregnancy with scar uterus (51%, 49/97). About 41 patients underwent abdominal total hysterectomy (42%,41/97) and 56 received subtotal hysterectomy (58%,56/97). (3) The number of patients were comparable between the two groups (50 vs 47;P>0.05). (4) The main surgical indication was uterine inertia (45%, 44/97). The main causes of uterine inertia were excessive uterine tension (45%, 20/44) and placental abruption due to gestational hypertension (32%, 14/44). Of all the indications, 29 patients in the first group (58%, 29/50) and 15 patients in the second group (32%, 15/47) suffered from postpartum hemorrhage. Pathological placenta embedment occurred in 15 patients in the first group (30%, 15/50) and 25 patients in the second group (53%, 25/47). The incidences of postpartum hemorrhage due to uterine inertia or pathological placenta embedment were significantly different between the two groups (both P<0.05), respectively. (5) In the first group, the average preoperative blood loss was (2 900±1 900) ml, and the average intraoperative amount of infused white&red blood cells was (5.9±3.5) U, with the average operation time of (2.2 ± 1.8) hours and the average in-hospital duration of (7.8 ± 2.3) days. In the second group, the average preoperative blood loss was (3 100± 2 200) ml, and the intraoperative amount of infused white&red blood cells was (6.2± 5.2) U, with the average operation time of (2.5± 2.1) hours and the average in-hospital duration of (7.9 ± 2.9) days. There was no significant difference between the two groups in any of these indicators (P>0.05). Postpartum hemorrhage was usually treated with uterine packing in the first group, but was preferentially treated with potent uterine contraction agents, arterial ligation, uterine balloon compression or B-Lynch suture in the second group. The therapeutic effects of these new treatments were significantly better than uterine packing (P<0.05). Conclusions The incidence of emergency obstetric hysterectomy did not change significantly in the past decade. However, the indications and intraoperative interventions have changed significantly in the second five years compared with the first five years. The main surgical indications were uterine inertia and postpartum hemorrhage due to pathological placenta embedment. Therefore, strict control of caesarean section indications was important to reduce emergency obstetric hysterectomy.

Objective Many studies have suggested that cardiovascular risk factors seem to be more common in psoriasis patients than in general population.In this study we aimed to investigate the prevention and treatment of cardiovascular risk in psoriasis patients by Framingham cardiovascular risk assessment in patients with psoriasis vulgaris and normal people using Framingham score.Methods We conducted a prospective study including 90 outpatients with psoriasis vulgaris and 137 controls without psoriasis from October 2015 to October 2016 in our hospital.All psoriasis patients were diagnosed clinically and histopathologically.The severity of psoriasis was assessed according to the psoriasis area and severity index (PASI) score.Along with a thorough medical history and physical examination, serum lipid profile, blood pressure and fasting plasma glucose tests were carried out.The 10-year Framingham risk score (FRS) for general cardiovascular disease included indexes concerning age, gender, total cholesterol, HDL-cholesterol, systolic blood pressure and smoking history.Results We found the 10-year FRS was significantly higher in patients with psoriasis vulgaris than in controls (P<0.05).The 10-year FRS was in positive relation with gender(r=0.358), age(r=0.678) and course of disease(r=0.257).No relation has been found in 10-year FRS and psoriasis features(r=0.184, P>0.05).No significance was found in the 10-year FRS of patients with mild and severe psoriasis (P>0.05).FRS was significantly higher in male patients and in patients above 50 years old (P<0.05).Conclusion Psoriasis patients, especially the older male patients, tend to have high risks of cardiovascular disease.Therefore, risk assessment for cardiovascular diseases should be conducted in psoriasis patients, and complications should be actively prevented and treated.

Objective To explore the developmental characteristics of different functional levels of autism and the diffe-rence in children. Methods A total of 159 autistic children aged 13-71 months including 85 high-functioning autistic (HFA) chil-dren and 74 low-functioning autistic (LFA) children were evaluated for their developmental characteristics by the development scales from the psycho-educational profile-revised (PEP-R). Results Within the same age group, both HFA and LFA children had obvious unbalance in individual ability development (H=41.68~113.51, P<0.01). Impaired cognitive performance is most common in HFA children. The development of cognitive performance was inconsistent with cognitive expression while the gross motor development was normal. The ability development in LFA children were all impaired, especially in imitation, cogni-tive performance and cognitive expression. With increasing age, the scores of imitation, perception, cognitive performance, cog-nitive expression and overall development quotient were increased gradually in HFA children (P<0.05) while the scores of cogni-tive performance and overall development quotient were decreased in LFA children. Conclusions Autistic children tend to have abnormal developmental progress and order, and individual ability development varies by functional level in autistic children with increasing age.

Objective This study aims to analyze if high sensitivity C Reactive Protein (hs-CRP) was a independent risk factor of acute kidney injury(AKI) after A type aortic dissection surgery.Methods Clinical data of the 169 patients who underwent A type acute aortic dissection surgery from February 2009 to October 2010 were collected.Patients without preoperative detection of hs-CRP,patients with preoperative infection and patients diagnosed infection before AKI were excluded.Enrolled patients were divided into AKI group and non-AKI group,and according to using RRT or not,the patients were divided into RRT group and non-RRT group.All the factors were evaluated by means of univariate and multivariate logistic regression analysis to identify relative risk factors of AKI.Results AKI occurred in 95 cases(56.2％),Using RRT in 8 cases (4.7％).hsCRP is an independent risk factor of AKI(OR =0.975,95％ CI 0.952-0.999,P =0.041).hs-CRP and aortic cross clamping time were the independent risk factors of using RRT,The in-hospital mortality was significant difference between RRT group and non-RRT group (P ＜ 0.05).The area under the ROC curve of hs-CRP on RRT diagnosis was 0.733,95％ CI 0.570-0.896,P =0.026.The sensitivity of CRP ＞ 30.42 mg/L warning AKI need RRT was 87.5％,the specificity was 53.4％.Conclusion AKI after A type aortic dissection surgery was a severe complication and RRT associated with in-hospital mortality,hs-CRP was higher in acute aortic dissection patients.The level of hs-CRP and aortic cross clamping time were independent risk factors of AKI and RRT.

ObjectiveTo analyze the clinical characteristic of the nasal type extranodal NK/T cell lymphoma(ENKL)as well as the therapeutic effects for different treatment methods and element that would affect prognosis.MethodsReview and analyze the 27 patients with pathologically confirmed ENKL patients received radiotherapy (3 cases),chemotherapy (9 cases),combination of radiotherapy and chemotherapy (15 cases),3 of whom received auto-HSCT.Detailed B symptoms,lactate dehydrogenase (LDH),performance status(PS)scores,international prognostic index(IPI),Ann Arbor stage and therapeutic modality were included in univariate analysis.ResultsThe average overall survival time was 32 (2-42) months.The 1,2and 3 year overall survival (OS) rates were 79.5 ％,71.6 ％,53.7 ％,respectively.The 2-year overall survival of patients who was early stage (stage Ⅰ + Ⅱ ) was 83.3 ％,and those who was advanced stage(stage Ⅲ+Ⅳ) was 62.3 ％ (P =0.368).Among the patients in early stage,after radiotherapy or chemotherapy,4 cases achieved OR (overall response) which is complete remission (CR) or partial remission (PR),9/10 in combination of radiotherapy and chemotherapy achieved OR. While among those in their advantage stage,the OR in chemotherapy is 2 cases,2/5 in combination of radiotherapy and chemotherapy.In univariate analysis,age and short-term response were main factors of survival(P ＜0.05).ConclusionTo treat the nasal ENKL in the early stage,radiotherapy can achieve a better effect,while combination of radiotherapy and chemotherapy is an important method for patients in advantage stage.Age and short-term response may be.prognostic factors of nasal type ENKL.

Objective To investigate the expression and its significance of BMI-1 gene in leukemia patients.Methods BMI-1 gene level was assessed by reverse transcription polymerase chain reaction (RT-PCR)in acute leukemia patients,chronic myeloid leukemia(CML)patients,chronic lymphoblastic leukemia(CLL)patients,and bone marrow mononuclear cells(BMMNC)as normal controls,as well as leukemia cell line K562.The expression of BMI-1 gene in leukemia and the relationship was explored.Results The expression of BMI-1 gene was positive in leukemia cell line K562.but negative in 10 controls as well as in CLL.The BMI-1 gene was expressed in 15.4% of CML patients and 47.1% of AL patients.The positive expression of BMI-1 gene in CML-CR was significandy lower than that in CML-BP (P＜0.05).Conclusion BMI-1 gene was over expressed in leukemia patients,and may be related to curative effect of the disease.It may be used for leukemia treatment targeting the provision of new sites.

Objective To explore the effects of traditional Chinese medicinal herbs (TCMHs) on the expression of tyrosinase gene, melanogenesis and proliferation of melanocytes and elucidate the mechanism of TCMHs in promoting melanogenesis. Methods Seven TCMHs including Herba Ecliptae, Spica Prunellae, Caulis Spatholob, etc, which were known to be effective in activating tyrosinase in vivo, were selected. Brownish guinea pigs were selected as the experimental model. The mRNA in situ hybridization (ISH), Schmorl-staining and dopa-oxygenase staining were performed to observe the effects of TCMHs on gene expression of tyrosinase, melanogenesis and melanocyte proliferation. Results The mRNA ISH showed that these seven drugs, especially Herba Ecliptae,Spica Prunellae and Tribulus terrestris could significantly increase the number of positive cells and the intensity of hybridization signal in the treated group as compared with that in the control group (P 0.1). Conclusions These results suggested that these 7 TCMHs including Herba Ecliptae can upregulate the gene expression of tyrosinase, enhance the melanogenesis and promote the proliferation of melanocytes.
