Cloning and identification of differentially expressed genes or proteins is helpful not only for finding the functions of genes and proteins, but also for discovery of the mechanism of some diseases. Some methods have been developed for screening differentially expressed genes, such as differential display RT-PCR (DDRT PCR), subtractive hybridization (SH), DNA chip technique, and serial analysis of gene expression (SAGE). In subtractive hybridization, there have advanced three improved methods which include representational difference analysis (RDA), suppression subtractive hybridization (SSH), and full-length-gene-obtainable subtractive hybridization. For obtaining differentially expressed proteins, scientists have only two choices so far. One is two-dimentional gel electrophoresis. The other is phage display antibody repertoire library technique. Since all of the methods above have their own advantages and disadvantages, they should be used according to different needs.screening, differentially expressed genes, differentially expressed proteins

Several important issues about internal strength massage and Shaolin Internal Qigong were discussed in this article, which verified the following aspects:Shaolin Internal Qigong was written into the massage textbook formally in 1960; Special material Shaolin Internal Qigong was first proposed in 1963; Internal strength massage schools were first proposed in 1979's National Massage Symposium. The author holds that Shaolin Internal Qigong is not the Kungfu from Shaolin Temple, and it has nothing to do with Dharma; Shaolin Internal Qigong of Massage exercises belongs to external Gong, the internal Qigong content of Xingqi Neishi need to be excavated; The method of stick-beating with mulberry stick of Internal Strength Massage is closely related to the patting method of Yi Jin Jing school in the Ming and Qing Dynasties and Zhen Ting method ofThe Golden Mirror of Medicine.

Objective To assess the influence of timing of tracheostomy performed on ICU patientswith mechanical ventilation support for long-term.Methods A retrospective study was carried out in 94 patients under mechanical ventilation support with tracheostomy from January 2012 to October 2014.The patients were divided into early stage group (group A) in which the tracheostomy was done within 7 days after endotracheal intubation and late stage group (group B) in which the tracheostomy was performed at above 7 days after endotracheal intubation.The differences in lengths of mechanical ventilation support (MVS),ICU stay,and hospital stay,incidence of ventilator-associated pneumonia (VAP) and mortality were compared between two groups using nonparametric statistics.Results Compared with group B,there were statistically significant reduction in duration of mechanical ventilation (7d vs.17 d;P ＜ 0.05),shorter length of ICU stay (10 d vs.19 d;P ＜ 0.05),and lower incidence of VAP (21.05％ vs.36.84％;P ＜ 0.05) in group A.There were no significant differences in hospital stay and mortality between two groups (P ＞0.05).There was a correlation between the duration of mechanical ventilation and timing of tracheostomy (R2 =0.680) and a correlation between the length of ICU stay and the timing of tracheostomy (R2 =0.662) was found.Conclusions Early tracheostomy has a significant positive impact on critically ill patients hospitalized in this ICU.These results support the tendency to balance the risk-benefit analysis in favor of early tracheostomy.

Objective To evaluate the risk factors for surgical site infection(SSI)following ankle joint and Pilon fracture surgery,and provide theoretical basis for the prevention of postoperative SSI.Methods Clinical data of pa-tients who underwent ankle joint and Pilon fracture surgery in a hospital between June 2005 to May 2013 were sur-veyed retrospectively,risk factors for SSI were analyzed.Results Among 356 patients with ankle joint and Pilon fracture surgery,22 developed 25 times of SSI,SSI rate was 6.18%,case infection rate was 7.02%.Univariate analysis showed that elderly patients (> 60 years old),history of diabetes,pre-operative calcaneal traction, perioperative irrational antimicrobial use,incision type,and long duration of operation (>3 h)were risk factors for SSI following ankle joint and Pilon fracture surgery (all P <0.05).Multivariate logistic regression analysis showed that the independent risk factors for SSI were incision type(OR,3.58[95%CI ,3.24-12.07]),history of diabetes (OR,2.75[95%CI ,1 .54-4.75]),duration of operation(OR,2.15[95%CI ,1 .32-3.64]),and patients age(OR, 1 .68[95%CI ,1 .25-2.37]).Conclusion Occurrence of SSI following ankle joint and Pilon fracture surgery is related to multiple factors,corresponding prevention and control measures should be taken to reduce the occurrence of SSI.

Objective To investigate the clinical value of clinical application in diagnosis of prostate cancer (PCa) by prostate biopsy guided by rectal ultrasound contrast guided biopsy.Methods One hundred and ninety-eight patients with prostate in Punan Hospital of Pudong New District of Shanghai were investigated.According to different detection methods, the research objects were divided into two groups, the patients were performed with the ultrasound contrast guided biopsy as the imaging group (n =96), the patients with Doppler ultrasound guided biopsy as the ultrasonic group(n =102).The puncture Results were compared with pathological diagnosis.The positive rate of PCa and number of puncture needle were compared with the two puncture methods.The value of the application of the prostate biopsy guided by rectal ultrasound in diagnosis of prostate cancer was evaluated.Result One hundred and ninety-eight patients were all received pathological diagnosis,78 cases benign lesions, 120 cases were diagnosed as PCa.Thirty-six cases of benign lesions were confirmed by pathological biopsy, 60 case PCa.There were 42 cases of benign lesions in ultrasonic group, 60 case PCa.The positive rate of PCa in the imaging groupwas 62.5％ (60/96), the ultrasonic group was 58.82％ (60/102).There was no difference in Pca positive rate between the ultrasound group and the contrast group(x2 =0.104, P=0.747).The positive number of Pca in the imaging group was 28.50％ (17/60), the difference was statistically significant higher than that of the common group(18.80％ (11/60), P =0.001).The average of the patients in the imaging group was 8.19 needle,less than the ultrasonic group per capita 11.31 needle less.When f/tPSA less than or equal to 0.15, Pca positive rate of the contrast group was 46.55％ (27/55), higher than the ultrasonic group(9.30％ (4/43)), the difference was statistically significant (P =0.001);when f/tPSA more than 0.15, the positive rate of Pca in the contrast group was 92.11％ (35/38), less than the ultrasound group (94.92 (56/59)), the difference was not statistically significant (P =0.89).Anal pain, hematuria and hematochezia in contrast group (7.29％ (7/96), 2.08％ (2/96), 10.42％ (10/96)) were significantly less than the ultrasound group(22.55％ (23/102), 8.82％ (9/102), 23.53％ (24/102)), the difference was statistically significant (P =0.003,0.039,0.014).Conclusion Under the guidance of ultrasound contrast, rectal biopsy has important diagnostic value for prostate cancer.Under the premise of reducing the number of puncture needle,can improvethe positive rate of Pca, reduce the pain of patients and the occurrence of complications after puncture.When f/tPSAless than or equal to 0.15,puncture positive rate in contrast group is higher than the ultrasonic group, puncture effect is better.

Objective To explore the influence of Helicobacter pylori (Hp) on the proliferation, apoptosis and expression of p27kipl protein of gastric epithelial cells in vitro. Methods SC, C-7901 cell pro-liferation was examined by flow cytometry after incubation with different concentration of NCTC11637. The effect of NCTC11637 on cell apoptosis was also evaluated by flow cytometryo And the expression of p27kipl of gastric epithelial cells was detected by immunohistochemical analysis and in situ hybridization, respectively. Results Cell proliferation was enhanced when co-incubated with the Hp in low concentration (3.4 x 104 to 1.9 x 105 CFU/ml) but inhibited in higher concentration (≥4.8×106CFU/ml). However, cell apoptosis was increase when co-incubated with the Hp in high concentration (≥9.6 ×105 CFU/ml) showing concen-tration dependent picture. In addition, the co-incubation of SGC-7901 with Hp led to decrease of the expres-sion of p27kipl protein but not mRNA in a Hp concentration dependent way. Conclusion Hp could effect the gastric epithelial cells apoptosis and proliferation directly and influence the expression of p27kips protein which might facilitate gastric carcinoma.

Objective To assess the value of C-reactive protein(CRP) for the prognosis of acute pulmonary embolism (PE). Methods 56 acute pulmonary embolism patients, confirmed by spiral computed tomography (sCT), magnetic resonance imaging(MRI), or pulmonary angiography (CTPA). CRP as well as electrocardiogram (ECG), echocardiography(UCG), blood gas analysis, were taken after admission. Results Among these patients,24 cases with higher CRP(≥10 mg/L),were diagnosed as massive (50.0%), sub-massive PE(45.8%), mini-massive (4.2%) or died(25.0%). 24 cases (100.0%) showed right heart dysfunction and 24 cases showed pulmonary hy-pertension on UCG, right ventricular 20 (83.8%) on ECG, 22 cases (91.7%) showed hypoxemia. 8 cases (33.3%) had syncope,and 9 cases (37.5%) had cardiogenic shock. CRP was lower than 10 mg/L in 32 patients, among whom,3 cases (9.4%) were with massive PE,6 cases (18.8%) were with sub-massive PE,23(71.8%) were with small PE,1 cases(6.3%) died. 13 (40.6%) had right heart dysfunction and 16(50.6%) had pulmona-ry hypertension on UCG, right ventricular on ECG in 15 cases (46.9%), hypoxemia in 11 cases (34.4%), syncope in 2 cases (6.3%), cardiogenic shock in 4 cases (12.5%). The occurrence of massive PE, mortality (P<0.01) and sub-massive PE (P<0.05)were statistically different between the groups with higher CRP and the groups with lower CRP. The ratio of right heart dysfunction, pulmonary hypertension, right ventricular overloading, hypoxemia had statistical significance (P<0.01). There was statistical significance in the occurrence of syncope, cardiogenic shock (P<0.05). Conclusions CRP can be used as a parameter for PE, and can be used to stratify risk levels for severi-ty and assess the effectiveness of treatment.
