Objective To investigate Chlamydia trachomatis infection and gene variants in child- bearing women in Beijing. Methods Endocervical samples were collected from 177 patients in a family planning clinic and a gynecologic clinic. C.trachomatis infection was screened with a fast diagnostic kit .Major outer membrane protein(MOMP) gene was amplified by a nested PCR . A 1.1kb amplified product was obtained and studied by restriction fragment length polymorphism analysis(RFLP). Variant domains of MOMP gene VS1,VS2,VS3,VS4 were sequenced with 373A automated sequencing system. Results C. trachomatis was found in 9 of 177 samples. Four samples were identified as F genotype, 3 E genotype and 2 D genotype. Variant domains of MOMP gene, VS1, VS2, VS3, VS4 were sequenced and the results were consistent with those of RFLP, however, mutations were found in MOMP gene in 4 samples. Conclusion C.trachomatis urogenital infection has been identified in a portion of child- bearing women in Beijing. C.trachomatis can be well genotyped with RFLP or gene sequencing of MOMP gene.

Objective To observe the self-efficacy and body image changes of the patients with oral and maxillofacial deformity in pre-and post-operative.Methods 183 patients with oral and maxillofacial deformity and 200 relatives as control group were measured by applying General Self-Efficacy Scale (GSES) of Chinese version and Self-rating Scale of Body Image(SSBI).Postoperative satisfaction degree was scored by applying attitude measurement method of interval scale.Perioperative GSES,SSBI score,and postoperative satisfaction degree were statistically analyzed.Results GSES score (26.79 ± 5.26) was lower than that in control group in preoperative (29.69 ± 5.37),and the difference was statistically significant (P ＜ 0.05).While SSBI score (24.35 ± 8.59) was higher than that in control group(11.04 ± 6.67),and the difference was also statistically significant (P ＜ 0.05).GSES score in postoperative(29.52 ± 3.80) was significantly higher than that in preoperative (P ＜ 0.05).SSBI score in postoperative(18.88 ± 8.19) was significantly higher than that in preoperative (P ＜ 0.05).Postoperative satisfaction was comparatively lower for the patients whose GSES score was higher than 32 and 36 for SSBI in preoperative.Conclusion Oporation can enhance the self-efficacy of patients with oral and maxillofacial deformity and reduce the incidence of patients with body dysmorphic disorder tendency.

Angiogenesis-related diseases involving EGF include acherosclerotic plaques, haemangioma, angiofibroma, tumor growth and arthritis. EGF may serve as a drug target and its antagonists may have important clinical applications.Peptide phage display libraries have been successfully applied in areas of finding ligands for enzymes, receptors, and many other molecules. A pⅧ-based peptide phage display library was panned with the cytokine EGF and several EGF-binding clones were selected based on ELISA and micropanning assays. The selected EGF-binders from peptide phage display library may be utilized in affinity chromatography in EGF downstream processing and even act as potential antagonists of EGF if their affinity is further improved through secondary library strategy.

Objective To explore the feasibility of using the consensus of European Working Group on Sarcopenia in Older People(EWGSOP) to diagnose sarcopenia among community-dwelling women aged from seventy to seventy-nine in Shanghai.Methods Twenty-two healthy community-dwelling women were recruited as the subject group(group S),and another ten young girls were randomly selected as the control group(group C).The anthropometry,bioelectrical impedance analysis(BIA)and dual energy X-ray absorptionmetry(DEXA)were used to evaluate the circumferences of upper and lower limbs,and the dimension of muscle mass,according to relative appendicular skeletal mass(RASM)and skeletal muscle index(SMI).The grip dynamometer and isokinetic dynamometer were used to measure the muscle strength of upper and lower limbs.The ten meters gait speed,functional reach test,timed up and go test,Berg balance scale and short physical performance battery were all applied to assess the physical performance.The criteria of EWGSOP consensus were applied to diagnose the situation of sarcopenia.Results Firstly,the average biceps circumference and fat mass of upper limbs in group S were significantly higher than group C (P＜0.01),while no significant differences were observed in the muscle mass(P＞0.05).Secondly,RASM values gained from BIA and DEXA in S group were significantly higher than C group(P＜0.05),while the SMI values of the former were significantly lower than the latter(P＜ 0.01).Thirdly,absolute grip strength,relative grip strength and other bio-mechanical indexes of lower limbs in the s group were significantly lower than the C group(P＜0.01);the relative grip strength showed significant correlation with most bio-mechanical indexes of lower limbs.Fourthly,the physical performance in group S declined significantly compared with that of the c group(P＜O.05),and no significant correlation was found between muscle strength and physical performance of upper limbs except the absolute grip strength and gait speed.The prevalence was 0％ according to the RASM index,while the prevalence was 63.6％ and 45.4％ according to the BIA and DEXA respectively.Conclusion The assessing pattern from EWGSOP consensus could not be simply copied to applying on Chinese old people due to serious difference between RASM and SMI.The combination of SMI+relative grip strength+ TUG/SPPB/Berg may be better than the classical mode of RASM+absolute grip strength+gait speed in diagnosing sarcopenia.

[Objective ] Intrastriatal Parr interneurons are considered to be the junction between striatal input and output neurons. This study purposes to confirm the morphology of Parr neurons and their distribution in striatum. [Method] Adult male SD rats were perfused and the brains were removed. The sections were conducted with a semiconductor-frozen microtome, then single labeling and double labeling were immunocytochemically conducted with PAP technique. Positive neurons were observed, counted, and calculated, and analyzed with SPSS. [Results] The distribution of Parr positive neurons in striatum was inhomogeueous, and was the most dense in the dorsal lateral area (P<0.001) ; the distribution of Parr positive neurons in matrix compartment was apparently more than patch compartment (82.0% vs 18.0%, P<0.001); Parr positive neurons in striaturn were medium-sized cell bodies with polygonal or oval in shape (mean diameter is 11.68 μm), and were larger in the lateral area than that in the medial area (P<0.01) ; the positive dendrites were dense and smooth without dendrite spines; the positive axons 1 were slender and their collaterals extended in striatum. [Conclusion] The characteristic of Parr positive neurons collecting mostly in lateral striatum and matrix eompartment, as well as their traits of intemeurons, indicated that they would affect the striatal projection neuronal function.

ObjectiveTo observe the effect and safety of postoperative patient-controlled epidural analgesia with dezocine plus ropivacaine in patients underwent hysterectomy.Methods60 patients,ASA Ⅰ ～ Ⅱ,undergoing hysterectomy operation.were randomly divided into two groups.0.225％ ropivacaine with 0.005％ dezocine ( DR group) or 0.225 ％ ropivacaine with 0.003％ morphine (MR group) were given epidurally after surgery,respectively,with an initial loading dose 5m l,basal dose of 2ml/h,PCA dose of 0.5ml and lockout time of 15 min.Visual analogue score(VAS),Bruggemann comfort scale(BCS),Ramsay sedation score(RSS),PCEA effective compression of the times and adverse effects were determined and compared at 1 h,4h,8h,12h,24h 36h and 48h after operation.PCEA effective compression of the number and incidence of adverse reactions were observed.ResultsThere were no significant differences in VAS,BCS,RSS and PCEA effective compression of the times between two groups( all P ＞ 0.05 ).The percentage of nausea,vomiting and pruritus were significantly lower in group DR than that in group MR( all P ＜0.05).ConclusionPatient-controlled epidural analgesia with dezocine plus ropivacaine in patients underwent hysterectomy had analgesic effect and safety,with less advers eeffects.

Objective To explore the influence of cognitive-behavioral intervention on the anxiety and oral health-related quality of life in adult orthodontic patients.Methods 152 adult orthodontic patients whose MDAS scores were greater than 11 were divided into the intervention group and the control group according Multistage Grouping Process.The former were treated with MBT appliance combined with cognitive-behavioral intervention,and the latter were treated with MBT appliance only.The State-Trait Anxiety Inventory(STAI) was adopted to evaluate anxiety in all patients during orthodontic treatment,and the UK oral health-related quality of life questionnaire(OHRQoL-UK) was adopted to evaluate the oral health-related quality of life in all patients before and after orthodontic treatment,respectively.Results 1.After 3 and 6 months cognitive-behavioral intervention,the scores of SAI in the intervention group(50.37±9.18,35.65±8.92) were significantly reduced compared to the control group(56.62± 10.52,54.13± 10.03) (P＜0.01).After 6 months cognitive-behavioral intervention,the scores of TAI in the intervention group(47.92±6.82) were significantly reduced compared to the control group(51.52±7.41) (P ＜0.05).2.After the orthodontic treatment,the scores of OHRQoL-UK in the intervention group(58.27±13.43) were significantly improved compared to the control group (51.99± 11.69) (P＜ 0.01).3.The oral health-related quality of life after the orthodontic treatment were significantly related to post-treatment anxiety of adult orthodontic patients(r=-0.192 ～-0.459,P＜ 0.05).Conclusion Cognitive-behavioral intervention can effectively reduce anxiety and improve the oral health-related life quality in the adult orthodontic patients.
