Trauma is one of the main reasons for the death and disability in children.Ultrasonic tech-nology has been applied in the early assessment and diagnosis of trauma.it is quick,effective,non-invasive, fast imaging,mobile and suitable for different patients and different parts of the body.It has been used to as-sess the organs in patients with severe trauma widely.

Objective To investigate serum levels of β-human chorionic gonadotrophin (β-HCG) and progesterone (P) in early pregnant women,and their relation to luteal maintenance therapy for early pregnancy protection.Methods One hundred and thirty five infertility women treated in Department of Gynecology and Obstetrics of Beijing Chaoyang Hospital from January 2007 to December 2011.Total 150pregnancy cycles,including 84 with intrauterine insemination (IUI) and 66 with natural conception,were divided into two groups:normal intrauterine pregnancy group (group A,n =80) and early pregnancy loss group (group B,n =70).Medical history,ultrasonic findings,serum female hormone,P and β-HCG levels at early pregnancy stage were analyzed.Results The age of group A and group B was (30.0 ± 3.9) years and(30.7 ± 4.9) years,respectively (P ＞ 0.05).The follicle-stimulating hormone/luteinizing hormone in group A and group B was 1.57 ±0.96 and 1.56 ± 1.08 ; the estradiol levels in two groups were (152 ±66) pmol/L and (147 ± 69) pmol/L,respectively (both P ＞ 0.05).There were no differences in dominant follicles and endometrial thickness between groups A and B (P ＞ 0.05).Ovulation promotion and luteal support treatments were adopted in both groups:50％ (40/80) of cycles in group A received ovulation promotion,73％ (58/80) of cycles received luteal support,while 44％ (31/70) and 76％ (53/70) received in groups B,respectively.The levels of serum progesterone in group A during 14-21 d,22-27 d and ≥ 28 d after ovulation were higher than those in group B at each time points (P ＜ 0.0l).There were no significant differences in serum progesterone levels between women with luteal support treatment and those without luteal support treatment in both groups (P ＞ 0.05).Conclusion Dynamic monitoring of serum progesterone level in early pregnancy may be used as an auxiliary index for prediction of pregnancy outcome,but it may not be an indicator for luteal maintenance therapy.

Gastrointestinal microbiota is a huge and complex system that has multiple influential factors. As an exogenous pathogen,Helicobacter pylori(Hp)may interact with gastrointestinal microbiota. It has been revealed that Hp infection led to an increase in Lactobacillus acidophilus in intestinal tract and a decrease in Actinobacteria,Bacteroidetes and Firmacutes in stomach. Proton pump inhibitors and antibiotics,the major components of eradication regimens for Hp infection,may also have an impact on gastrointestinal microbiota. On the other hand,gastrointestinal microbiota interferes with Hp’s attachment into gastric mucosa. Probiotics combined with eradication therapy could benefit the eradication rate of Hp infection and reduce adverse events.

Objective To study the expression of Sox2 in human prostate cancer and pericarcinomatous tissue,and the relation between its expression and the pathological type and clinical stage of prostate cancer.Methods Immunohistochemisty,Western blot and reverse transcription-polymerase chain reaction (RT-PCR)were used to detect the expression of Sox2 in 86 cases of prostate cancer tissues and 40 cases of pericarcinomatous tissues.The relation between Sox2 expression and the pathological type and clinical stage of prostate cancer was analyzed.Results The expression of Sox2 in prostate cancer tissue (71.9％) was significantly higher than that in pericarcinomatous tissue (7.5％),and the difference was statistically significant (x2 =53.98,P ＜ 0.05).Sox2 expression in prostate cancer tissues was significantly related to Gleason score (x2 =19.49,P ＜ 0.05).The positive rate of Sox2 in lymphatic metastasis group and negative lymphatic metastasis group was 92.3％ and 73.3％ respectively,and the difference was statistically significant (x2 =3.95,P ＜ 0.05).While there was no significant difference among clinical stages (x2 =0.16,P ＞ 0.05).Moreover,Western blot and RT-PCR revealed that the expression of Sox2 in prostate cancer tissue was significantly higher than that in pericarcinomatous tissue (t =-2.93,P ＜ 0.05 ; t =3.29,P ＜ 0.05).Conclusion The high expression of Sox2 is closely related to the Gleason score and lymphatic metastasis of prostate cancer,but not to the clinical stage.The overexpression of Sox2 may play an important role in formation,differentiation and metastasis of prostate cancer.

Purpose:To detect the expression of a novel i nh ibitor gene of apoptosis,survivin,in gastric cancer and in gastric carcinoma MGC -803 cell line,also to analyze its correlation with the expression of COX-2. Methods:In 93 stomach carcinoma tissues and 20 normal gastric tissues , the expression o f survivin and COX-2 were examined by using the streptavidin-biotin peroxidase (SP) method. Results:In contrast to negative expression in normal gastric mucosa,survivin was express ed in 66 of 93(71%) cases of gastric cancer samples,Overexpression of survivin i n gastric carcinoma MGC-803 cell line was also found,There was a relationship b etween survivin gene expression and degrees of differentiation,lymph node metast ases and TNM stages.The expression of survivin was positively correlated with th at of COX-2(liner index of Pearson=0.227 P

Purpose:To investigate the roles of artesunate on the proliferation and apoptosis of gastric carcinoma cells,also to explore it s possible mechanism of anticancer effects. Methods:The inhibition on the proliferation of cultured stomach carcinoma cell line(MGC-803) was observed by using MTT analysis.and apo ptosis was assessed by flow cytometry together with transmission electron micros copy.Using reverse transcriptase polymerase chain reaction,the expression of sur vivin mRNA was evaluated before and after action of artesunate on malignant cell s. Results:The proliferation of MGC-803 was inhibited notably by artesunate with a dosage-dependant character(P

Now the in-service staff have been permitted to apply for master's degree with the same educational level aspostgraduates. This is a signal reforming policy in postgraduate education and degrees management area in China. Manyhigher professionals are trained for our socialist modernization construction by this education technology. Although therelatively perfect system to manage this project was established in China, there are still some problems demandingprompt solution on the management thoughts, management process as well as management methods in some authorizedunits.

Objective To evaluate the effects on mechanical ventilation in ICU patients with dexmedetomidine merely and combined with dezocine, fentanyl, respectively.Methods Fifty-seven patients with mechanical ventilation in ICU were collected during Jun till Dec in 2016, 35 males and 22 females, aged 18-75 years, and classified into three groups with random number table method, among whom there were 17 patients treated with dexmedetomidine, 20 patients treated with dexmedetomidine combined with dezocine and 20 with dexmedetomidine plus fentanyl, the general condition, pain score, MAP and HR were compared before and after the treatment, ideal treatment time and mechanical ventilation time were also compared among the different groups.Results There were no statistical differences in the general condition, CPOT score, MAP and HR at different points and mechanical ventilation time.Whereas, the time of ideal sedation and analgesia was significantly faster in group C than that of groups A and B (P<0.05).Conclusion Dexmedetomidine combined with dezocine can reach the ideal analgesic effect more rapidly than dexmedetomidine solely or combined with fentanyl.

Objective To study the role TGF-? 1 expression in the gastric cancer and to evaluate its clinical and pathological significance.Methods The expression of TGF-? 1 was studied by using S-P immunohistochemical technique in 20 cases of normal gastric tissue and 46 cases of gastric carcinoma.Results in the gastric cancer patients,the positive rate of TGF-? 1 expression was 100%,but there was 50% positive rate in the normal gastric tissues.The TGF-? 1 expression in group with lymph node metastasis was higher than that without lymph node metastasis.Conclusion TGF-? 1 plays an important role in the progress of gastric cancer.
