Objective To study blood lipids levels of patients with ischemic cerebral vascular disease (ICVD).Methods The blood lipids levels were measured in 2886 subjects with ICVD enrolled from 1991 to 2004,in which 1430 subjects from 2000 to 2004 were classified into a sub-group;400 healthy persons receiving physical examination were enrolled as controls.Results The blood TC,TG and LDL-C levels were significantly higher in the sub-group than those in the control group.Both in males and females, the morbidity of abnormal blood lipid metabolism and blood lipids level gradually increased with the age and the lapse of decades.Total cholesterol level of male younger than fifty,averaging (4.43?0.51) mmol/L, increased to (4.96?0.85) mmol/L after fifty years old.The same thing happened to females,from (4.30?0.49) mmol/L to (5.01?0.90) mmol/L.TG and LDL-C increased in patients older than fifty compared with those younger than fifty.In the groups above 50 years old,the blood lipids levels of females were significantly higher than those of males.The morbidity of abnormal blood lipid metabolism of male increased from 24.5% in (1991 to 1994) to 38.1% (2001 to 2004) and of female from 22.3% (1991 to 1994) to 38.5% (2001 to 2004).Conclusions Abnormal blood lipid in Foshan is one of the most important reasons to ICVD.

A secretive expression vector of Pichia pastoris system which can be used for the direct cloning of PCR products was constructed,and was verified through the expression of recombinant cellobiohydrolase II in Pichia pastoris.A randomly selected fragment was amplified with properly designed primers by PCR.The XhoI and Eam1105Ⅰ restriction sites were included in the 5'end of the fragment,and the Eam1105Ⅰ and XbaI restriction sites were included in its 3'end.The PCR amplified product was inserted into the P.pastoris expression plasmid pPICZ?A through XhoI and XbaI restriction sites and the resultant plasmid was digested with Eam1105Ⅰ,and lastly the big fragment was recovered,generating the P.pastoris expressive Tvector pPICZ?T.Then the cellobiohydrolase II of T.reesei was successfully expressed in P.pastoris with this expressive Tvector.Such results indicated that the constructed expression Tvector was convenient for PCR product cloning,and was effective for heterologous protein expression in P.pastoris.On the other hand,the application of the expression Tvector avoided the introduction of additional amino acids at the Nterminus of the expressed protein,which generally occurred when normal expression vectors were used in secretive expression system.

The incidence of male infertility increased year by year, which seriously affects family welfare and social development. This article reviews and sorts out recent years’ studies on acupuncture treatment for male infertility. The results show that acupuncture treatment has produced a good clinical effect on this disease. Some progresses have been made in clinical acupuncture point selection, operating methods, complex treatment and therapeutic mechanism. The clinical effect and the mechanism of action of acupuncture treatment for this disease have been deeply explored from symptom differentiation and classification, acupoint selection and prescription, acupoint stimulation mode, and combined acupuncture and moxibustion therapy so as to provide new ideas for clinical acupuncture treatment and basic study.

Objective To investigate the clinical effect of radiofrequency ablation (RF) combined with digital subtraction angiography (DSA)-guided percutaneous ethanol injection sclerotherapy in the management of high-return flow venous malformation (VM).Methods Forty-one patients,who were diagnosed as high-return flow VM with clinical and radiographic evidence,were divided into the observation group (n=19) and the control group (n=22) using a random number table.All high-return flow VM patients received DSA-guided percutaneous ethanol injection sclerotherapy while the patients in observation group were given radiofrequency ablation.The clinical effect,treatment times and adverse effect of the two groups were analyzed.Results The effectiveness of the observation group was significantly higher than those of the control group [94.7％ (18/19) vs 81.8％ (18/22)].The facial paralysis occurred in three patients (13.6％) after ethanol injection in the control group,while the observation group had no facial nerve injury after treatment.The patients in observation group had significantly fewer numbers of ethanol injection.Conclusions RF can improve the efficacy of high-return flow VM and reduce the number of ethanol injection.The scheme is safe and effective.

ObjectiveTo analyze the classifications of the abnormalities of cervical curvature and its treatments with manipulation. Methods209 patients with cervical lordosis were analyzed. The abnormalities of the cervical curvature were classified as over-curvature (>45°), hypo-curvature (0°～30°), the straightened cervix (0°), backward curvature(0°～―20°), multiple curvatures (the cervical curvature showed "S" shaped). The C_5 subluxation were restored with manipulation in patients with hypo-curvature and straightened cervix, or other vertebra subluxation in multiple curvatures. Results1~4 yeared follow-up, 127 cases were excellently well being, 59 were well being, 23 were improved.ConclusionManipulation is effective on abnormalities of cervical curvature.

The intubation of conventional transesophageal echocardiography (TEE) probes into patients causes serious esophagus irritation,and thus the use of TEE probes in pediatric practice is limited.In this study,we aimed at the development of a special probe which could be inserted through the nasopharyngeal cavity into the esophagus to obtain the same high-quality echocardiography images as those obtained by conventional TEE and improve patients' experience.During the examination,the patients felt relaxed for a longer time and cooperated with the sonographers in the process of cardiac catheterization conducted in the surgery room or the intensive care unit (ICU),resulting in improved accuracy of the diagnosis and timely administration of appropriate treatment.Two years ago,Prof.Xin-fang WANG put theories into practice by inserting the probe through the nasal cavity and pharynx into the esophagus of volunteers to successfully detect the heart and great vessels at the retrocardiac space.Later,Prof.Ming-xing XIE performed the transnasal TEE examination in 12 atrial septal defect (ASD) patients and proved the safety and reliability of this method,which could become a new way for clinical diagnosis and treatment.
