Journal of Chinese Physician 2010;12(8):1019-1021
Objective To study the effect of using improved loop electrosurgical excision procedure for diagnosis and treatment of cervical diseases. Methods The clinical data of 70 cases of cervical intraepithelial neoplasia or carcinoma in situ from January 2006 to Decemder 2008 in our hospital was collected.The operation time, the mean volume of blooding, days of blooding, relationship between the mean blood and areas of pyramid area of pyramid was compared between study group and control group. Improved loop electrosurgical excision procedure was executed on 21 cases of study group ( CIN Ⅰ 4 cases, CIN Ⅱ 10 cases,CIN Ⅲ4 cases, CIS3 cases ) and loop electrosurgical excision procedure was used on 49 cases in control group (CIN Ⅰ7 cases,CIN Ⅱ21 cases, CIN Ⅲ 16 cases, CIS5 cases). Results Blood loss [(16.57 ±17. 47 ) ml], operative time [( 9.07 ± 3.34 ) min] and postoperative bleeding time [(9.10 ± 2.23) d] in study group were lower than that in control group [( 39.80 ± 37.43 ) ml, ( 12. 19 ± 5.34 ) min, ( 10. 49 ±2. 76)d], and the differences were statistically significant ( P < 0. 05 ). Cervical cone volume [( 14. 70 ±13. 35 ) mm3] and blood loss [(32. 83 ± 14. 32 ) ml] were positively correlated ( r = 0. 430, P < 0. 05 ). No significant difference between prognosis of two groups was found( P >0. 05 ). Conclusion There was positive relationship between the averge blood loss in surgery and areas of pyramid excision. It'd be better to stitch the ramus descendents of uterine artery at three and nine o'clock of the cervix uteri, when the patients were expected to have large pyramid areas and abundant blood flow who may bleed more than normal. which can reduce the blood loss after surgery and reduce the time of surgery.

Chinese Acupuncture & Moxibustion 2015;35(4):413-416
According to topographic anatomy, pathogenesis and by retrieving, summarizing and analyzing literature regarding needle-knife and needles with knife-edge for carotid cardiac syndrome, it is found out that clinical misdiagnosis rate of carotid cardiac syndrome is considerably high. Needle-knife and needles with knife-edge could significantly improve the clinical symptoms of carotid cardiac syndrome, showing characteristic and advantage in treatment, but it is deficient in technique standard and efficacy criteria that should be united and authoritative. Researches regarding pathogenesis of carotid cardiac syndrome are not systematic. Clinical observation regarding long-term efficacy and relapse of needle-knife and needles with knife-edge treatment is rare. It is believed that the awareness on carotid cardiac syndrome should be increased to reduce misdiagnosis; scientific and standardized technique standard and efficacy criteria should be established; systematic and comprehensive researches regarding mechanism of needle-knife and needles with knife-edge for carotid cardiac syndrome should be launched; besides, clinical discussion regarding its long-term efficacy should start to provide a better clinical guideline.

Objective To evaluate the effectiveness and safety of percutaneous subclavian venous catheterization through the point of insertion medial to the middle of clavicle in infants.Methods One hundred and fifty infants(88 male,62 female)aged 1-12 months scheduled for major operation were enrolled in this study. Subclavian venous catheterization was performed via supraclavicular approach.The needle was inserted at a point midway between the middle of clavicle and the inner third of clavicle(group Ⅰ,n=50)or at the point where the posterior border of sterno-cleidomastoid muscle(SCM)meets the upper border of clavicle(Yoffa method group Ⅱ, n=50)or at the posterior border of SCM,0.5-1.0 cm above the upper border of clavicle(modified James method,group Ⅲ,n=50).The overall success rate,the success rate at first attempt,the failure rate,the depth of insertion and complications were recorded.Results The 3 groups were comparable with respect to sex ratio,age and body weight.There were no significant differences in overall success rate and failure rate among the 3 groups. The success rate at first attempt in group Ⅰ(86%)was significantly higher than that in group Ⅱ(74%)and group Ⅲ(80%)(P<0.05).The depth of insertion was significantly greater in group Ⅰ[(2.21+0.28)cm]than in group Ⅱ[(1.79?0.33)cm]and group Ⅲ[(1.84?0.38)cm].No pneumothorax and in advertent arterial puncture and nerve injury occurred in the 3 groups.Conclusion Supraclaricular subclavian venous catheterization through the insertion point medial to the middle of clavicle is better than the conventional methods(Yoffa,James) in terms of success rate at first attempt in infants.

HIV-1 integrase (IN) is an essential enzyme for retroviral replication. There is no analogue for this enzyme in human cells so that inhibition of IN will not bring strong effect on human body. Thus, HIV-1 IN has become a rational target for therapy of AIDS. This review provides a comprehensive report of alpha, gamma-diketo IN inhibitors discovered in recent years. Compilation of such data will prove to be beneficial in developing QSAR, pharmacophore hypothesis generation and validation, virtual screening and synthesis of compounds with higher activity.
