Precision medicine promotes the development of individual medicine,but also brings about problems to patients' personal privacy,especially for the protection of genetic information.The priority is to establish relative legal framework and specific regulations.America has issued Precision Medicine Initiative:Privacy and Trust Principles and Data Security Policy Principles and Framework,which have become the pioneer in the establishment of related principles and systems.In order to promote the development of Chinese laws and regulations,it is essential to use American practice as reference according to the specific national conditions,and definitely build up several principles,such as informed consent,honesty and credibility,reasonable care and benefit balance,in order to provide perfect genetic data protection system for patients.

OBJECTIVE:To investigate therapeutic efficacy and recurrence rate of vaginal administration of lactobacillus com-bined with chlorquinaldol-promestriene for senile patients with atrophic vaginitis. METHODS:150 senile patients with atrophic vag-initis were selected and divided into group A,B,C according to random number table,with 50 cases in each group. Group A was given Lactobacillus vaginal capsules,2 capsules,qd (at bedtime);group B given Chlorquinaldol-promestriene vaginal tablets,1 tablet,qd(at bedtime);group C given Chlorquinaldol-promestriene vaginal tablets,1 tablet,qd(at bedtime),and Lactobacillus vaginal capsules,2 capsules,qd,next morning,implanting into vagina. 3 groups received treatment for 18 d. Clinical efficacy, vaginal health score,vaginal symptom score and vaginal pH value were observed in 3 groups,and the occurrence of ADR and re-currence rate during follow-up period (12 months) were recorded. RESULTS:The total effective rate of group C was 94.00%, which was significantly higher than group A(72.00%)and B(74.00%),with statistical significance(P<0.05). Before treatment, there was no statistical significance in vaginal health score,vaginal symptom score and vaginal pH value among 3 groups (P>0.05). After treatment,vaginal health score of 3 groups were increased significantly,while vaginal symptom score and vaginal pH value were decreased significantly;and the improvement of above indexes in group C were significantly better than in group A and B,with statistical significance(P<0.05). No obvious ADR was found in 3 groups during treatment. The recurrence rate of group C during follow-up period(4.00%)was significantly lower than that of group A(18.00%)and group B(20.00%),with statistical significance(P<0.05). CONCLUSIONS:Vaginal administration of lactobacillus combined with chlorquinaldol-promestriene for se-nile patients with atrophic vaginitis can effectively relieve clinical symptoms and signs,improve vaginal cleanliness,regulate the lo-cal pH value and reduce the risk of recurrence,with good safety.

Objective To investigate the regulation of protein kinase C(PKC) to the expression of β-1,4-galactusyhransferase- Ⅰ ( β-1,4-GalT- Ⅰ ) and the influence on cytoskeleton and adherence ability of human umbilical vein endothelial cells(HUVECs) when stimulated by lipopolysaccharide (LPS). Methods Cultured HUVECs were pretreated by various PKC inhibitors or phorbol 12-myristate 13-acctate( PMA), an excitomotor of PKC respectively for 30 min, then stimulated by LPS for 4 h. β-1,4-GalT-Ⅰ expression were detected by RT-PCR and Western blot, expression of β-1,4-galactosylated carbohydrate chains and cytoskeleton were assayed by immumofluorescence, and adherence ability of HUVECs was observed by endothelialmonocyte cell adherence test. Results Up-regulated expression of β-1,4-GalT- Ⅰ and β-1,4-galactosylated carbohydrate chains in HUVECs stimulated by LPS were suppressed by PKC inhibitors and increased by PMA. F-actin and β-1,4-GalT- Ⅰ were partly co-localized in HUVECs. PKC inhibitor inhibited the effect of LPS on the distribution of F-actin and β-1,4-GalT- Ⅰ. Adherence ability of HUVECs enhanced by LPS was significantly suppressed by PKC inhibitor. Conclusion PKC signal transduction pathway may participate in regulating β-1,4-GalT-Ⅰ expression in endothelial cells stimulated by LPS. Furthermore, polytypes of PKC may participate in this regulating process; PKC might regulate cytoskeleton reorganization and adherence ability of EC through β-1,4-GalT-Ⅰ during inflammation.

Objective To investigate serum alpha2-Heremans-Schmid glycoprotein ( AHSG ) level and its relationship with associated clinical parameters in subjects with simple overweight and obesity. Methods Forty-nine subjects with obesity ( OB group) , 176 subjects with overweight ( OW group) , and 327 individuals with normal weight ( NW group) were randomly enrolled. The clinical data were collected and serum levels of AHSG and adiponectin ( APN) were determined by ELISA. The associations of serum AHSG level with other clinical parameters were assessed by Pearson correlation analysis and multiple linear regressive model. Results Serum AHSG levels were higher in OW and OB groups than that in NW group[(276. 30 and 302. 10 vs 241. 60)μg/ml], being especially higher in OB group (P<0. 05 or P<0. 01). Serum AHSG level in NW group was positively associated with fasting plasma glucose, homoeostasis model assessment of insulin resistance index, C-reactive protein (CRP), triglycerides, and free fatty acids ( FFA ) , but negatively associated with age and APN. In OW and OB groups, AHSG was also positively associated with body mass index, waist hip ratio(WHR), and low density lipoprotein cholesterol(P<0. 05 or P<0. 01) except the aforementioned clinical parameters. In multiple linear regression model, AHSG was positively associated with WHR, CRP, and FFA, and was negatively associated with APN ( P<0. 05 or P<0. 01). Conclusion The raised AHSG level in overweight and obese subjects may be a risk factor for obesity-related diseases.
