Objective To clarify malaria infection and the incidence in first Chinese medical team of United Nation peacekeeping mission in Democratic Republic of Congo and evaluate the effect of prevention measures so that provide reference for studying on malaria prevention and the precautionary measures for the follow-up personnel in Africa. Methods 43 cases (male 30, female 13) were observed between Apr. and Dec. 2003 when they were deployed in D.R.of Congo. Eliminating mosquito was used to decrease the density, including the usage of driving mosquito machine, killing mosquito lamp and chlorine cyanogens chrysanthemum ester, ”Prevent malaria-3”and COTECXIN as the precautionary medicines. Plasmodiums in blood were checked periodically. The cases with positive result of blood test and without clinical symptom was considered as infection, otherwise as disease with symptom appeared. Results The density of mosquito in house decreased. 3 cases (male 2, female 1) suffering from malaria, the incidence was 6.98%. Plasmodium was found in 39 individuals (male 26, female 13), the infection rate was 90.70%. The incidence was the lowest compared with contingents from other countries. Conclusion It was effective that these measures taken by reducing mosquito density and ”Prevent malaria-3”and COTECXIN usage in Chinese medical team during peacekeeping mission .

Objective:To test the effects of roxithromycin(RM) on TNF? and IL-6 release from periodontal ligment fibroblasts(PDLCs) stimulated with lipopolysaccharide(LPS).Methods:PDLCs of passage 4~8 were cultured with RM at 2,20 and 200 ?g/ml respectively with 10 ?g/ml of LPS.The control cells were cultured with culture medium only.The cultures were continued for 3,6,12 and 24 hours respectively.ELISA method was used to measure TNF-? and IL-6 released into the culture medium from PDLCs in the different groups.Results:LPS increased both TNF-? and IL-6 release from PDLCs at all the time points(P

Background and purpose: Docetaxel/cisplatin are widely used in chemo-naive patients with advanced non-small cell lung cancer(NSCLC),but the standard 3-weeks'project of docetaxel caused significant toxicity.We performed this study to compare the effect and toxicity of modified and standard 3-weeks'docetaxel/cisplatin as first line chemotherapy for advanced NSCLC.Methods:68 patients with stage ⅢB or Ⅳ NSCLC(proven by histology or cytology) were randomly divided into two groups,modified(A) and standard(B) chemotherapy.Group A: docetaxel 75 mg/m2,divided into 2 days,ivgtt d1 and d 8,cisplatin 25 mg/(m2?d),ivgtt d 1-d 3,q3w;Group B: docetaxel 75 mg/m2,ivgtt d 1,cisplatin was administered as Group A,q3w.The effect and toxicity were assessed after two cycles and one-year survival was followed up.Results:There was no CR in both groups.10 PR,20 SD,4 PD were found in group A,the overall response rate is 29%;whereas 11 PR,20 SD,3 PD were found in group B,the overall response rate is 32%.The one-year survival rate were 38% and 35% in group A and B,respectively.There were no significant difference about the overall response rate(P=0.793) and one-year survival rate(P=0.801) between group A and B.The rates of grade Ⅲ/Ⅳ neutropenia were 18% and 47% in group A and B respectively.The difference was statistically significant(P=0.010).Conclusions:In comparison with the standard 3-weeks'docetaxel/ cisplatin chemotherapy,the modified one has similar response rate but lower hematologic toxicity,and thus it was well tolerated.

Objective To research the important of prenatal diagnosis and effect of intervention to fetal hydrothorax. Methods The cases of fetal hydrothorax (n=5) were obtained from the Shengjing Hospital,China Medical University between December 2014 and May 2015. All pregnancies were uncomplicated, excluded congenital organic and chromosomal abnormalities during prenatal diagnosis and with a 37 average gestational weeks. The case 1, 2, 4 were unilateral hydrothorax and the case 3, 5 were bilateral. We performed an antenatal thracocentesis to case 1, 2, 3. In case1, the hydrothorax increased rapidly after 5 days, and the patient underwent a cesarean section and ex utero intrapartum treatment (EXIT);in case 2, the fetal heart rate was decreased to 40-50 bpm suddenly during thracocentesis, and we performed an emergent cesarean section and EXIT for the patient; in case 3, the patient underwent thracocentesis and a meanwhile cesarean section and EXIT procedure. We performed a conservative management to case 4, 5, the hydrothorax resolved spontaneously during the pregnancy and after birth, both patients underwent cesarean section. Results All fetuses were survived, the neonates of case 1, 2 and 3 underwent assited mechanical ventilation, thoracic close drainage, then discharged after hydrothorax resolved and feeding tolerance;in case 4, there was no respiratory distress and hospital treatment;in case 5, the neonate underwent assited mechanical ventilation and conservative management, the hydrothorax has resolved gradually. Conclusions The prenatal diagnosis and antenatal intervention (thracocentesis) may play an important role in fetal hydrothorax treatment. In clinical, we should choose different plan according to the gestation weeks and classification of hydrothorax of the patient.

Objective To explore the correlation between thyroid peroxidase antibody (TPOAb) and outcomes during pregnancy and the effects of treatment on outcomes. Methods PubMed, Cochrane Library, Science Direct, Embase, Chinese Biomedicine, and Wanfangdata had been searched. Case-control and cohort studies about TPOAb and pregnancy outcomes were searched according to the inclusion and exclusion criteria. Fifty studies were finally recruited (all of cohort-studies, 10 for English and 5 for Chinese). Review Manager 5.3 were used to test the heterogeneity of the results among the different studies and amalgamate the effect size using fixed or random effect models. Results Meta-analysis showed TPOAb (+)with normal thyroid function increase the risks of miscarriage,and premature delivery, OR calculated were 2.02(95%CI:1.13-3.62, P=0.001)and 1.39(95%CI:1.11-1.76, P=0.005), while showed no relative risk to hypertensive disease,placental abruption in pregnancy and fetal growth restriction, OR calculated were 1.29(95%CI:1.00-1.67, P=0.080),0.42(95%CI:0.12-1.43, P=0.210)and 1.61(95%CI:0.23-11.12, P=0.100). TPOAb(+)with normal thyroid function increase miscarriage in in vitro fertilization and embryo transfer (IVF-ET), OR calculated were 2.14(95%CI:1.43-3.21, P=0.000). Levothyroxine (LT4) for patients of TPOAb(+)with normal thyroid dysfunction decrease adverse obstetric outcomes, OR calculated were 0.43(95%CI:0.22-0.85, P=0.020). Conclusions TPOAb(+)with normal thyroid function increase the risks of miscarriage,and premature delivery. TPOAb(+) with normal thyroid function increase miscarriage in IVF-ET. LT4 for patients of TPOAb(+)with normal thyroid dysfunction decrease adverse obstetric outcomes.

Objective To introduce the treatment efficacy of using allograft muscle ligament anatomical to rebuild anterior cruciate ligament (ACL) of knee joint under the arthroscopy.Methods Sixty-two cases patients with ACL rupture in anterior cruciate ligament reconstruction under arthroscopy.Allograft ligaments were used as graft,a bone tunnel was established in the proximal tibia and distal femur,and the graft was fixed by the extrusion screw.After the operation,the knee joint was fixed for 12 weeks,and the subjective evaluation was carried out according to the Lysholm and Larson knee score standards;in order to assess the stability of the ligament and the functional recovery of the knee joint,objective evaluation was carried out according to Lachman test in patients.Results The preoperative average Lysholm scale was (43.1±2.1) points,the final average score of 2 years after the reconstruction of the ligament was (91.0+2.3) points,there was significant difference (t=3.460,P=0.001).The preoperative average Larson scale was (41.0±2.9) points,the final average score of 2 years after the reconstruction of the ligament was (90.1±3.5) points,there was significant difference (t=3.232,P=0.001).Lachman test results were negative in 62 patients at the end of the review.No serious postoperative complications occurred,no knee infection,deep vein thrombosis and stiffness.All the patients can be completely straight 1 year after operation,knees up to 120 degrees.All patients were satisfied with the function at the end of the follow-up,no joint instability,no re-rupture occurred during the follow-up period.Conclusion Using the allogeneic single beam anatomy of anterior cruciate ligament reconstruction under arthroscopy can obtain satisfactory clinical efficacy.

Objective:To analyse the evaluation and experience of clinical effect of minimally invasive drainage and craniotomy in the treatment of patient with epidural hematoa.Methods:100 cases of patients who were diagnosed as epidural hematoma from January 2015 to January 2016 were selected and randomly divided into two groups,where the control group were given craniotomy,and the observation group were given minimal invasive drainage.The effect of the surgery and the life qualities before and after treatment of the two groups were compared.Results:The effect of observation group is better than that of control group (P ＜ 0.05);craniocerebral defect and the re-hemorrhage incidence occurrence in the observation group were obviously lower than those in the control group,(0 ％,6 ％ vs 12 ％,20 ％) (P＜0.05).Conclusion:Compared with craniotomy,minimal invasive drainage in clinical treatment of epidural hematoma showed advantage in at smaller trauma,faster recovery,and better effect,thus deserving further promotion of clinic application.

Objective To investigate the dynamic changes of endoplasmic reticulum stress-related molecules including glucose regulated protein (GRP78), C/EBP homologous protein (CHOP), and caspase-12 in sciatic nerve of diabetic rats and explore its mechanisms.Methods Rats were randomly divided into normal control group (NC) and diabetes mellitus group (DM) that were induced by intraperitoneal injection of Streptozocin after 4 weeks of high-fat chow feeding.Sciatic nerves were isolated for three times at 4 weeks, 8 weeks and 12 weeks after induction of diabetes.The expressions of GRP78, CHOP,and caspase-12 were detected with quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot analyses.The morphology of sciatic nerve was investigated with electron microscope.Results With the extension of the course, demyelinating and axonal injury appeared in sciatic nerve of diabetic rats.The expressions of GRP78 mRNA and protein in DM group were significantly higher than NC group at 4 weeks and 8 weeks after induction of diabetes(P ＜0.05, P ＜0.01).The expressions of CHOP mRNA and protein in DM group were significantly higher than NC group at 8 weeks and 12 weeks after induction of diabetes (P ＜ 0.05).The expressions of caspase-12 mRNA and protein in DM group were significantly higher than NC group at 8 weeks after induction of diabetes(P ＜ 0.05, P ＜ 0.01).Conclusions Endoplasmic reticulum stress-related molecules (GRP78, CHOP, and caspase-12) contributed to the peripheral nerve injury of diabetic rats, and displayed dynamic changes.

Objective To discuss the methods and outcomes of twin reversed arterial perfusion sequence in different stage. Methods From August 2012 to December 2013, 11 cases were diagnosed with twin reversed arterial perfusion sequence (TRAP) by 3d color Doppler ultrasound in the Maternal ang Fetal Medicine Center ,Affiliated Shengjing Hospital, China Medical University, including 3 cases in stageⅠa, 7 in stageⅡa and 1 case in stageⅡb. We performed expected therapy to 3 cases in stageⅠa and 4 cases in stageⅡa [1 case (case 9) in stageⅡa developed to stageⅡb and was terminated by emergency cesarean section], radio frequency ablation (RFA) selective reduction to 3 cases in stage Ⅱa, emergency cesarean section to 1 case in stageⅡb. All cases except case 1,4 took cesarean section to terminate pregnancy and would be followed up on the aspect of infant′s growth. Results (1) 3 cases in stageⅠa were monitored by sequential ultrasound examination, all donors grew normally, in which 2 acardias arised spontaneous cessation of flow and were implemented of cesarean section after the normal period of gestation; 1 case suffered premature rupture of membrane and experienced the natural childbirth at 34 gestation weeks plus 5 days. The survived average labor weight was 2 923 g. (2) In the 7 stage Ⅱa cases, 3 cases were implemented of RFA selective reduction, 2 cases survived and the average labor gestation was 35 weeks plus 1 day and average labor weight was 2 050 g;in 3 expected therapy cases, 1 case suffered premature rupture of membrane at 34 gestation weeks plus 5 days and experienced cesarean section; 1 case was observed for 3 weeks and the donor was stillborn; 1 case progressed to stage Ⅱb and experienced cesarean section at 34 gestation weeks plus 5 days;and 1 case was lost of follow up. (3) For 2 cases of stageⅡb cases, one was progressed from stage Ⅱa during expected therapy; the other one had been already in stage Ⅱb since visiting and experimented an emergency cesarean section, but the neonate died of heart failure two days after labor. (4) 7 survived neonates were followed up, all had a normal condition compared to kids of the same age, except one suffering a congenital heart disease, patent ductus arteriosus and atrial septal defect and whose weight (6 kg at 7 months) was lighter. Conclusions We should make the diagnosis of TRAP as early as soon and choose appropriate therapy according to the stage. According to our research, cases in stage Ⅰa can undergo an expected therapy under a sequential ultrasound examination;cases in stageⅡa can undergo a RFA selective reduction to improve the prognosis of the donor, which can make a good perinatal outcome.
