1.Identification of human papillomavirus in vulvar intraepithelial neoplasia
Chinese Journal of Clinical Laboratory Science 2006;0(06):-
Objective To evaluate the rate and types of human papillomavirus (HPV) in vulvar intraepithelial neoplasia (VIN).Methods We detected HPV DNA in 67 lesion tissues collected from 40 VIN patients with PCR based reverse line blot hybridization and DNA sequencing. The PCR using GP5/GP6 primers in HPV L1 region resulted in a 150-bp fragment. When the PCR did not amplify the target DNA,another PCR using SPF1/SPF2 primers was performed to amplify the 65-bp fragment.Results HPV DNA amplified with primers GP5/GP6 was positive in 52.2% (35/67) of the lesions. Of the 32 negative lesions,26 (81.2%) were positive for HPV DNA amplified with SPF1/SPF2 primers. The total positive rate was 91.0% (61/67). Ninety percent of the HPV belonged to high risk types. Sequencing data showed that the genotypes of 31 mono-infection lesions were the same as those of the reverse line blot results,yet the sequences in 4 multi-infection samples could not be determined. Of the 26 SPF PCR products,24 could be sequenced. 80.6% (25/31) patients with multiple lesions displayed the same genotype,suggesting HPV in the different lesions from the same patient was monoclonal.Conclusion The high risk type of HPV is associated with vulvar intraepithelial neoplasia and may play an important role in the development of invasive vulvar carcinoma.

Objective To investigate the efficacy and safety of hypertonie saline enhanced radiofrequency ablation (RFA) in the treatment of liver cancer. Methods The clinical data of 42 patients with primary liver cancer (n = 28) or metastatic liver eancer (n = 14) who had been admitted to First Affiliated Hospital of Nanjing Medical University from September 2001 to December 2007 were collected. Forty-eight lesions were detected with a diameter ranging from 1.2 cm to 7.5 cm. RFA electrode and 20G needle were pricked into the target lesion under the guidance of B ultrasound or computed tomography (CT) through percutaneoas puncture or open approaches. An amount of 5-10 ml hypertonie saline was infused through the needle at regular intervals during RFA. All patients were followed up for 3-79 months. Contrast-enhanced ultrasound and CT scanning were performed postoperatively to determine the efficacy of RFA. The levels of alpha-fetoprotein (AFP) before and after treatment were compared using t test, and the survival of the patients were analyzed using a Kaplan-Meier survival curve. Results The AFP expression changed to negative in 14 out of the 18 AFP-positive patients, with statistical difference (t =7.703, P <0.05). The complete necrosis rate of tumors was 94% (45/48), and the necrosis rate of tumors with diameter of ≤4.0 cm reached 100% (35/35). The incidence of complication was 5% (2/42). No perioperative mortality occurred. The 1-, 2-, 3-year survival rates were 91%, 85% and 70%, respectively. Conclusions Hypertonic saline enhanced RFA in the treatment of liver cancer was proved to be safe and effective.

In this study, solvent evaporation method was used to preparing baicalin ethylcellulose microspheres for intranasal administration. The prepared microspheres were round with certain rough surface. The average drug loading and entrapment efficiency was (33. 31 ± 0. 045)% , (63. 34 ± 0. 11)% , respectively. As the characteristic crystalline peaks of baicalin were observed in the microspheres sample, the result of X-ray diffractometric analysis indicated that the baicalin was present in crystalline form after its entrapment in ethylcellulose matrix. By investigating the thermogram of microspheres sample, it was found that endothermic peak of baicalin was shifted from 211. 8 °C to 244. 2 °C and associated with the first broad endothermic peak of ethylcellulose. This could confirm that baicalin was loaded into ethylcellulose, nor simply physical mixture. The powder flowability test exhibited that the specific energy of microspheres was 3. 57 mJ . g-1 and the pressure drop was 2. 22 mBar when air kept the speed of 2 mm . s-1 through the powder bed with the force was 15 kPa. The consequence of the baicalin in vitro released from microspheres showed that the pure baicalin sample displayed faster (90%) release than microspheres sample (75%) in 7 h. Fitting model for release curve before 7 h, the results showed that the pure baicalin sample and the microsphere sample accorded with first order model (R2 = 0. 990 4) and Riger-Peppas model(R2 = 0. 961 2), respectively. Ex vivo rabbit nasal mucosa permeability experiment revealed that the value of cumulative release rate per unit area of the microsphere sample was 1. 56 times that of the pure baicalin sample. This provided the foundation for the in vivo pharmacokinetic study.

The international NGOs have been playing an important role in global health governance, and also represent a channel for countries to exert international influence. However, the Chinese NGOs are not actively in-volved in global health so far. This purpose of this paper is to analyze and show the picture of the social and political context of NGOs in China, to learn from the experience of emerging global health-related NGOs through describing their development, provides a strategy for China to support NGO participation in the global health governance, and to put forward recommendation on how to develop China’s global health NGOs based on experiences from international counterparts. The results of this paper found that China has a better international environment, which is a beneficial opportunity for the country to engage in global health governance. Domestic social NGOs are developing progressive-ly, while they are still being harnessed by political safety considerations, for example being affiliated to public admin-istrative system and policy orientation development. However, this would possibly not obstruct health-related NGOs for its minimal political relevance as it is oriented at professionalism, i. e. specialization, public service attributes and relevance to public governance. Therefore, health-related NGOs can have more support from governments since their number is relatively small, with less foundation ( they are undeveloped) and less participation in international cooper-ation ( they lack international involvement) . International experience indicates that supports from governmental enti-ties represent a backbone of the emerging institutions in the participation into the global health programs. The author suggests that the Chinese government should establish a specific global health development strategy of “prioritizing and improving the whole” and setting up the global development strategy in the county. The government should attach more importance to the government-owned and affiliated and private-capital-supported (social elites) NGOs, guide and subsidize them to the international stage, to engage intensely in global health.

The global health system is undergoing dramatic reforms, which would further bring about signifi-cant changes in key global health stakeholders. As a key actor and decision maker in global health system, NGO owns extensive experiences in global health governance and can provide a systematic experience for China’s participa-tion in global health decision-making as a reference model. This paper aimed at studying the roles of NGOs in the field of global health, the roles which can be summarized in four aspects of advocacy, implementation, support, and community mobilization. In addition, NGOs also developed some potential risks and unexpected impacts on global health governance. As represented by some typical examples, there occurred conflicts of interests between some NGOs and the local governments. A number of local health systems suffered from a considerable brain drain of health personnel to NGOs, especially the health officials and technical staff, which weakened the country’s health workforce and system. The financing model driven by external donors could weaken the influences and capacity of local govern-ments on health planning. As a key member involved in global health, we that suggested China and Chinese NGOs should strategically and rationally borrow their experiences and try to avoid these risks.
