Objective: To observe the clinical effects of acupoint injection therapy plus massage on primary dysmenorrhea (PD).
Methods: Ninety patients with PD were randomly divided into a treatment group or a control group, 45 cases in each group. The treatment group was treated by injection of Vitamin K3into Sanyinjiao (SP 6) plus massage on Diji (SP 8). The control group was treated by oral administration of Ibuprofen sustained-release capsule. Before and after the treatment, visual analogue scale (VAS) was adopted to assess pain degree of the patients. The therapeutic effects were observed after continuous treatment of three cycles of menstruation.
Results: After treatment, VAS scores were obviously decreased in both groups and the differences were statistically significant (allP<0.05). The difference in VAS score after treatment was more significantin the treatment group than that in the control group (P<0.01). The total effective rate was significantl higher in the treatment group than that in the control group (P<0.05).
Conclusion: Acupoint injection therapy plus massage for PD is effective and better than simple oral administration of Ibuprofen sustained-release capsule.

Objective To explore the relationship between nonalcoholic fatty liver (NFALD)and apolipoprotein E (ApoE)gene polymorphism in Shanghai undergraduate students. Methods A cross-sectional survey was performed in 4 148 students from Shanghai Tongji University. Quesgionary, physical measurement, ultrasonography and biochemical parameters were used to diagnose NFALD. In patients with NAFLD and 200 healthy subjects (served as control), ApoE genotypes were determined by PCR-RFLP. Results (1)Totally 398 subjects were diagnosed as NAFLD (prevalence 9.6%). Body mass index, waist-to-hip ratio, triglycerides, total cholesterol, alanine transaminase, aspartate aminotransferase and γ-glutamyltransferase in NAFLD group were higher than those in control, which were related to the degree of NAFLD (P＜0.01). (2)ApoE genotypes distributions were significantly different between two groups (χ2=10.52, P＜0.01). In NAFLD,E4/4 genotype frequency (5.5%)increased, and E3/3 (61.8%)decreased . (3)Unconditional logistic regression showed that E4/4 were closely associated with lipid profiles. Conclusion ApoE point mutations 112 and 158 may cause different dyslipidosis. E4/4 genotype seems to be one of the genetic predisposition factors of NAFLD.

To explore the effects of Shengmai injection and Xuesaitong injection, compound Chinese herbal medicines for replenishing qi and activating blood, on ventricular fibrillation threshold, heart structure and connexin 43 (Cx43) expression in rats with myocardial infarction (MI).

A method was developed for the determination of zeranols (α,β-zearalanol,α,β-zearalenol,zear-alanone,zearalenone) with RRLC-MS/MS in the plant tissue. The samples were extracted with acetonitrile and reextracted with aqueous alkaline solution,cleaned up with MAX column and then determined by RRLC-MS/MS using multiple reaction monitoring ( MRM) scan mode. The results showed that the working curves were linear in the range of 0 -20 μg/kg. The limits of detection ( LOD) of zeranols were 0.5 μg/kg and the limits of quantification (LOQ) was 1. 0μg/kg. Extraction recoveries for zeranols ranged from 75. 8% to 105.4% and RSD was between 2.4% and 12.1%. The method is suitable for the determination of zeranols in the plant tissue.

Objective To investigate the correlation between gene polymorphism within human β defensin 1 (DEFB1) and fungal susceptibility to severe sepsis through case-control association study.Methods A total of211 patients with severe sepsis in ICU were enrolled in the present case control study. Sepsis in this study was diagnosed according to the definition of American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference in 1992 and 2002. Based on the development of fungal infection during ICU stay, all 211 patients were divided into fungal infection group (Group Ⅰ) and control group (Group C). Alleles and genotypes of-1816A/G, -390A/T, -52A/G, -44C/G and-20A/G within DEFB1 gene were assayed in all 211 patients by means of DNA direct sequencing, Allele-specific PCR amplifications or high-throughput site-specific TaqMan assay. Genetic analysis was employed to calculate the distribution frequency of haplotypes. The correlation between the genomic variations (allele,genotype and haplotype) and fungal infection was analyzed by Chi-square test or Fisher's exact test.Odds ratio (OR) was employed to reflect the correlation degree of genetic factor with fungal susceptibility to severe sepsis. Results Group Ⅰ enrolled 80 patients, of whom 43 pstients were male, at age of (60.81 ± 18.30) years. Group C enrolled 131 patients, of whom 80 patients were male, at mean age of (60.42 ± 17.03) years. No significant difference was found between two groups in aspect of gender and age (P＞0.05). The genetic locus of -1816A/G, -390A/T, -52A/G, -44C/G and -20A/G of both groups were in agreement with Hardy Weinberg equilibrium. No significant difference was found between two groups in the distribution of allelic frequencies and genotype frequencies (P ＞0.05). No significant difference was found in the distribution frequency of four common haplotypes of the above five genetic locus such as AAACG, ATGCA, GTGGG and ATACG (all P ＞ 0.05). Conclusions Genetic locus of -1816A/G, -390A/T, -52A/G, -44C/G and-20A/G within DEFB1 gene have no correction with fungal infections in severe sepsis, suggesting that DEFB1 gene polymorphism may not serve as a key genetic marker for the predisposition to fungal infection in severe sepsis.

Objective To discuss the initial expression of serum procalcitonin (PCT) in patients with severe traumatic brain injury (TBI) and determine the potential value of PCT to predict the neurological outcome.Methods A retrospective analysis was made on patients admitted due to severe TBI (GCS≤8 points) from July 2011 to August 2012.Mortality and neurological outcome of the survivors were determined using Glasgow outcome scale (GOS) at 6 months after TBI.Results A total of 52 patients (39 males and 13 females),at median age of 38 years (range,15-65 years) were included in the study.Twenty-eight patients had good outcome (GOS of grade Ⅳ-Ⅴ),whereas 24 patients had poor outcome or died (GOS of grade Ⅰ-Ⅲ).Within 24 hours after TBI,serum PCT level was significantly higher in patients with bad outcome compared to those with good outcome (0.778 ng/ml:0.094 ng/ml,P ＜0.01).Enhanced PCT level presented a close correlation with the poor outcome (r =0.657,P ＜0.01).Area under the receiver operating characteristic curve (ROC) was 0.879 [95％ CI (0.757,1.000)].A cutoff value of 0.2 ng/ml had a sensitivity of 100％ and a specificity of 72.2％.Once the PCT level was superior to 4.7 ng/ml,none of the patients regained consciousness.Conclusion PCT is a simple and effective method for prediction of the outcome after severe TBI.

Post competency-based medical education complies to the development and philosophy of modern medicine. This paper completely illustrates how to construct a scientific and diversified assessment evaluation system guided by post competency for medical students which combines formative assessment and summative assessment. Through the objective measurement and timely feedback of various abilities of medical students, the closed-loop feedback system of assessment and evaluation can be constructed to guide the exploration and practice of teaching process in reverse.

One hundred children aged 8-10 years and 100 adults aged 18-45 from their families in three townships Baoshan,Mingcheng,and Yantongshan of Panshi city,Jilin province were selected in April 2009. In addition,50 pregnant or lactating women,and their 50 infants aged 0-2 years were selected.The median level of iodine in salt at household was 30.2 mg/kg and that of drinking water was 2.8 μg/L.The median levels of urine iodine in school age chidren ( 196.5 μg/L),during pregnancy( 198.5 μag/L),lactation( 224.9 μg/L),and in infants (209.0 μg/L) all were optimal according to World Health Organization criteria.Only the median urine iodine in adults ( 269.0 μg/L) was more than adequate.The prevalence of goiter evaluated by B-ultrasound was 1.8％ in 8-10year-old children.The incidences of various thyroid dysfunctions were low in these residents,such as subclinical hyperthyroidism ( 2.1％ ),subclinical hypothyroidism ( 1.5％ ),and hyperthyroidism ( 1.2％ ). Subclinical hypothyroidism occurred mostly in adults (2.7％),pregnant women ( 1.7％ ),and lactating women ( 1.8％ ) ; and subclinical hyperthyroidism occurred mostly in 8-10 years old school chidren (4.5％) and lactating women (3.6％).These results show that the current iodized salt content has no harmful effect on thyroid function of rural residents in Jilin province.
