In recent years , along with the continuous accumulation of clinical experiences and the improvement of surgical devices, the percutaneous coronary intervention (PCI) has become a perfect treatment method and been widely used in the clinic . Hence , the coronary heart disease ( CHD ) patients have received better treat-ment results. However, the in-stent restenosis is still a big problem after PCI. The combination of Chinese and modern medicine in the prevention of restenosis has become a focused hotspot . In order to further under-stand this issue , this article discussed the Chinese and modern medicine mechanism in order to provide more thoughts for clinical practice .

Objective:To investigate the distribution of abnormal eating behaviors among middle school girls in Beijing and the psychological factors having influence on these behaviors Methods: HDI and ESC-21 were used to investigate 636 female middle school students in Beijing Results: (1) According to the BMI of the subjects, 80 3% of the subjects answered that they had paid attention to their weight and stature (2) The mean BMI of the subjects were 19 38, which is in the normal range, but their ideal body mass index(IBMI)was lower than the normal standard (IBIM

Objective: To develop a computer game addiction inventory (CGAI) for Chinese college students. Methods:A primary inventory made by the authors was applied to 477 college students from 8 universities in Beijing for exploratory factor analysis, and then to 405 college students for confirmatory factor analysis. Results: After exploratory factor analysis, a questionnaire consisted of 33 items were established, which had four factors: dependence and addict behavior, emotion arousal, functional impairment, and shame and un-satisfaction. These four factors could explain 55.1 of the total variance, were confirmed by confirmatory factor analysis (?~2/df=2.304; IFI=0.885; CFI=0.884; NFI=0.813; RSMEA=0.057). The internal consistency of the questionnaire was good (r=0.77~0.94), the test-retest reliability was 0.907. Criteria validity shown by higher scores in addiction group than normal control was also satisfying. Conclusion: The CGAI has good psychometric features and could be applied to college students.

Objective To analyze the clinical value of ovarian surgery in the treatment of primary ovarian mucinous carcinoma patients with fertility requirements.Methods 51 cases with fertility requirements with primary ovarian mucinous carcinoma who received surgical treatment were analyzed.The postoperative serum follicle stimulating hormone (FSH) and luteinizing hormone (LH),estradiol (E-2),anti Mullerian hormone (AMH) were deteced.The patients were followed up for 3 years,the survival rate and fertility were observed.Results Of 51 patients underwent surgery,postoperative 7d,14d,the FSH,LH levels in serum were higher than before operation (F=24.198,21.554,all P<0.05),E-2,AMH,PSV values were lower than before operation (F=24.407,35.028,11.064,all P<0.05).During the follow-up period to June 2015,there were 4 patients died of tumor recurrence,2 patients were lost to follow-up,45 patients survived,the survival rate was 88.23%.Of 45 patients survived,41 patients were normal menstrual cycle,menstruation,menstrual cycle 26-31 d,average (28.2±2.2)d;4 patients with irregular menstruation.Married women in the follow-up of 44 cases,including 28 patients with successful pregnancy,the pregnancy rate was 63.64%,there were 4 cases of spontaneous abortion,pregnancy in 3 patients because of abortion,pregnancy examination found 17 cases of abnormal pregnancy,4 cases of premature delivery.Conclusion In patients with primary ovarian mucinous carcinoma,it is feasible to use fertility preserving function,and the pregnancy rate is high,but the follow-up and monitoring should be strengthened to avoid the bad prognosis.

BACKGROUND:β-catenin is the most critical signaling molecule in the Wnt/β-catenin signaling pathway, which is involved in the regulation of cellproliferation, differentiation and tissue self-healing balance.
OBJECTIVE:To construct a stableβ-catenin over-expression lentivirus-mediated vector and to transfect mesenchymal stem cells line for investigating its effects on proliferation and migration of mesenchymal stem cells.
METHODS:Over-expression vector, PLV-EF1A-catenin-RFP, was constructed and transfected the 293T cellto infect mesenchymal stem cells, and positive cells were selected with puromycin. The up-regulated efficiency of targetingβ-catenin gene at mRNA level was detected by real-time quantitative PCR, the effect on proliferation of mesenchmal stem cellwas assayed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and growth curve, and the migration ability was detected by Transwel motility assay.
RESULTS AND CONCLUSION:The lentiviral vector targetingβ-catenin gene was constructed successful y, and a stable mesenchymal stem cellline that up-regulatedβ-catenin was established. Real-time quantitative PCR results showed that the expression ofβ-catenin gene was efficiently up-regulated by infecting PLV-EF1A-catenin-RFP (P<0.05). The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and growth curve showed that celldoubling time was shortened after infected with pLV-EF1A-catenin-RFP (P<0.05), indicating that the over-expression of theβ-catenin gene successful y increased the proliferative capability of mesenchymal stem cells. The Transwel assay also showed similar increasing results on the migration ability (P<0.01). The lenvivirus-mediated over-expression of theβ-catenin gene can be used to increase the proliferation and migration abilities of the mesenchymal stem cells.

BACKGROUND:As an important cytokine, interleukin-6 regulates immune responses in inflammation sites and has an autocrine/paracrine activity that stimulates osteoclast formation and bone resorption, which is related to bone remodeling during orthodontic tooth movement.
OBJECTIVE:To investigate the effects of orthodontic force on the expression of interleukin-6 mRNA in the periodontal tissue of rats.
METHODS:In situ hybridization was performed to measure the expression of interleukin-6 mRNA at 1, 3, 5, 7, 10 and 14 days after the application of orthodontic force on the maxil ary first molars of rats.
RESULTS AND CONCLUSION:The expression of interleukin-6 mRNA was observed at a low level in the normal periodontal tissue of rats. After the application of force, the induction of interleukin-6 mRNA was observed to reach a maximum on day 3 and to decline thereafter. The expression of interleukin-6 mRNA can be evoked by orthodontic force but with a certain self-limiting. As a multifunctional cytokine, interleukin-6 plays a very important role in periodontal remodeling during orthodontic tooth movement.

Objective To evaluate the clinical efficacy of nerve-related acupoints electrical stimulation in preventing urinary retention after hemorrhoid surgery. Method Ninety-seven patients were randomized into two groups: the treatment group received nerve-related acupoints electrical stimulation 1 h after Milligan-Morgan hemorrhoidectomy for mixed hemorrhoids, while the control group was taken as a blank control. The incidence of postoperative urinary retention, residual urine volume after the first urination, general urinary condition score, and satisfaction evaluation were compared between the two groups. Result The incidence of postoperative urinary retention and residual urine volume after the first urinary were lower, and the general urination condition and satisfaction evaluation were higher in the treatment group compared to those in the control group. Conclusion Nerve-related acupoints electrical stimulation can prevent and reduce the adverse reactions such as urinary retention after hemorrhoidectomy, and it can effectively protect the bladder function and improve the prognosis.

Objective To assess the safety and effect of intraoperative cell salvage (ICS) during cesarean section.Methods This was a case-control study in which 60 gravidas who received ICS (ICS group) and 60 gravidas who received allogenic transfusion (control group) during caesarean section in Obstetrics and Gynecology Hospital of Fudan University during January 2014 to December 2016 were enrolled.Subjects in the two groups were matched in age,gestational age,gestational complications (placenta increta,placenta previa,scarred uterine,leiomyomas and anemia) and hemorrhagic volume during cesarean section.Several indicators including complications of transfusion,postoperative recovery,expense of transfusion,as well as the complete blood count and body temperature before and after operation were compared between the two groups.T,rank-sum or Chi-square test was used for statistical analysis.Results (1) No significant difference in age,gestational age,twin gestation,complications,preoperative body temperature,or the volume of hemorrhage or transfusion was observed between the two groups (all P＞0.05).(2) The autotransfusion volume was 385 (161-583) ml in the ICS group.Fifteen cases (20.0％) in the ICS group also received additional transfusions of leukocyte-reduced red blood cell (RBC) suspension,fresh frozen plasma and cryoprecipitate and two cases (3.3％) received additional transfusions of leukocyte reduced RBC suspension and fresh frozen plasma.The two groups showed no significant difference in the cost of transfusion or per-capita transfusion volume of fresh frozen plasma or cryoprecipitate.However,the transfusion volume of leukocyte-reduced RBC suspension was lower in the ICS group as compared with that in the control group [M(P25-P75),1.9 (1.5-4.5) vs 4.1 (2.8-6.2) U,Z=-2.800,P=0.005].(3) There was no significant difference in complete blood count or coagulation function between the two groups before the operation.White blood cell (WBC) counts in the two groups were elevated following operation.Postoperative WBC count in the control group was higher than that in the ICS group,while the levels of RBC and hemoglobin were lower than those in the ICS group following operation (all P＜0.05).(4) No amniotic fluid embolism was reported in the two groups.Only one case of rash was reported in the ICS group,which was fewer than the transfusion reactions occurred in the control group [1.7％ (1/60) vs 13.3％ (8/60),x2=5.886,P=0.016].(5) The two groups showed no significant difference in preoperative temperature,the highest temperature within three days after operation or incision healing.Compared with the patients in the control group,those in the ICS group had shorter hospital stay [(4.7± 1.1) vs (6.3 ±1.8) d,t=3.341,P＜0.05].Conclusion ICS is a safe and effective measure for gravidas at higher risk of hemorrhage during cesarean section.

Objective To study the clinical value of magnetically controlled capsule endoscopy in diseases screening. Method We retrospectively analyzed 61 cases which were evaluated by magnetically controlled capsule endoscopy from March 2015 to December 2016. The items include operating time, the divergence rate score and cleanliness score of stomach. The consistency was compared between magnetically controlled capsule endoscopy and gastric duodenal endoscopy. Results 61 upper gastrointestinal tract studies were included. The mean age was (49.4 ± 11.6) years. No capsule retention, perforation or bleeding occurred. There was 98.4% patients, which cleanliness of stomach was good. There was 68.9% patients, which filling degree of stomach was good. The concordance rate of the two tests of gastrduodenoscopy and magnetically controlled capsule endoscopy was 89.9% (80/89). The concordance rate of the two tests was 78.9% (15/19) in esophageal and cardia, 92.9% (52/56) in stomach, 92.9% (13/14) in duodenum. Conclusion Our experience shows that magnetically controlled capsule endoscopy is a safe and useful tool for the diagnosis of upper gastrointestinal tract disease. The detection rate is similar to gastrduodenoscopy.

Objective To evaluate the effects of inhalation sevoflurane in the early ischemia and reperfusion on pulmonary inflammatory response in patients undergoing cardiac surgery with extracorporeal circulation (ECC). Methods Forty patients with rheumatic heart disease scheduled for elective valve replacement were randomly assigned into 2 groups (20 patients in each group): control group and sevoflurane group. In sevoflurane group, 2% sevoflurane was inhaled for 15 min before and after the ascending aorta was blocked, and also before and after the ascending aorta was opened. Paitents in control group didn′t inhale sevoflurane. Time was defined as the followings: after anesthesia and before skin incision (T0), immediately before ECC (T1), immediately after ECC (T2), 2 h after ECC (T3), 6 h after ECC (T4) and 24 h after ECC (T5). At T0, T2, T3, T5, the radial artery blood was obtained to detect the levels of plasma tumor necrosis factor-α(TNF-α), interleukin-8(IL-8) and soluble intercellular adhesion molecule-1(sICAM-1). At T1, T2, the pulmonary artery and pulmonary vein blood was obtained to detect the neutrophil count and calculate the differences between the vein and artery. At T0, T2, T3, T4, T5, the arterial blood gas was detected and differences of alveoli-arterial oxygen pres [P(A- a)O2], oxygenation index (OI), static compliance (Cst) were calculated. Results The levels of plasma TNF-α, IL-8 and sICAM-1 were higher at T2, T3, T5 than those at T0 in two groups (P<0.05). The levels of plasma TNF-α, IL-8 and sICAM-1 were decreased in sevoflurane group at T2 and T3, compared with those in control group (P<0.05). The neutrophil counts of pulmonary artery, pulmonary vein and the differences between the vein and artery were higher at T2 than those at T0 in two groups (P<0.05). The neutrophil counts of pulmonary artery, pulmonary vein and the differences between the vein and artery were decreased in sevoflurane group at T2 compared with those of control group (P<0.05). The level of P(A- a)O2 was higher at T2, T3, T4 and T5 than that at T0 in two groups (P<0.05). The level of OI was decreased at T2, T3, T4 and T5 compared with that at T0 in two groups (P<0.05). The level of Cst was decreased at T2, T3 and T4 compared with that at T0 in two groups (P<0.05). The level of P(A-a)O2 was decreased in sevoflurane group at T2, T3 and T4 compared with that in control group (P<0.05). The levels of OI and Cst were higher in sevoflurane group at T2, T3 and T4 compared with those in control group (P<0.05). Conclusions Severe pulmonary inflammation often occurs during cardiac surgery with ECC, and it can be relieved by inhalation of sevoflurane in the early ischemia and reperfusion.
