Objectives To observe the effects of varied doses of L-thyroxin sodium ( L-T4) on congenital hypothyroidism ( CH) and to determine appropriate dose for early therapeutic intervention. Methods Totally, 108 cases of confirmed CH were divided into two groups (54 in each group). All the cases were administered with L-T4 at varied doses( 10. 1? - 15. 0 ?g ? kg-1? d-1 for large-dose group and 6. 0 - 10. 0 ?g ?kg-1? d-1 for small-dose group) after their parents were trained for basic knowledge of CH by specialists. Their serum levels of T3, T4 and TSH, as well as their body height, weight and head circumference, were measured during follow-up. L-T4 was maintained at doses of 1. 0 - 4. 0 ?g ? kg -1 ? d-1 when their serum levels of T3, T4 and TSH returned to normal. Results All the 108 cases had their clinical symptoms quickly improved and development and growth accelerated after L-T4 substitution. Their serum level of T3 returned to normal in all cases, that of T4 did not return to normal in six cases of large-dose group and in 16 cases of small-dose group, and that of TSH did return to normal in 22 cases of large-dose group and in 39 cases of small-dose group, respectively, after one-month treatment, with a significant difference between the two groups. Cases in large-dose group gained more weight in average than those in small-dose group when they were three months old. Conclusions Early therapeutic intervention for babies with CH with L-thyroxin sodium of 10. 1 -15. 0 ?g ? kg-1? d-1 could quickly correct abnormal function of their thyroid and could avoid abnormal development of their intelligence due to CH.

Objective To study the effect of gambogic acid on apoptosis and autophagy in human hepatoma cells HepG2, and to detect its possible mechanism. Methods After exposure of HepG2 cells to gambogic acid at different concentration for 24 h, cell proliferation rates was determined by MTT assay, apoptosis rate was detected by the flow cytometry (FCM), formation of autophagic vacuoles was observed by the monodansyl cadaverine (MDC) fluorescence staining, expression level of apoptosis-related proteins Bax, bcl-2 and autophagy related protein Beclin 1 was detected by Western blot. Results HepG2 cell growth was inhibited by the gambogic acid dose dependence. After exposure to gambogic acid at 0, 2.0, 4.0 and 8.0 μmol/L for 24 h, cell apoptosis rate was significantly increased to 5.31 %, 29.18 %, 31.50 % and 46.09 %(P <0.05), MDC average fluorescence intensity was also significantly increased to 6.3 ±1.1, 82.6 ±4.5, 132.9±15.7 and 157.7±9.0 (P<0.01). Western blot showed that gambogic acid could promote the expression of apoptosis protein Bax (0.17 ±0.02, 0.75 ±0.06, 0.78 ±0.05, 0.89 ±0.10, P <0.05), and decrease the expression of anti-apoptosis protein bcl-2 (1.18 ±0.04, 0.90 ±0.06, 0.64 ±0.08, 0.57 ±0.05, P <0.05), meanwhile, it could also increase the expression of autophagy related protein Beclin (0.67±0.03, 0.92±0.04, 0.95±0.07, 1.04±0.06, P<0.05). Conclusion Gambogic acid can inhibit the growth of human hepatoma HepG2 cells by inducing apoptosis and autophagic cell death.

Objective :
To analyze the status and influencing factors of the intention of people aged 18 to 25 years to primary medical institutions and their satisfaction for health services in Zhejiang Province, so as to provide basis for the improvement of health services in primary medical institutions.
Methods:
During November and December in 2019,the 18-25 year-old people in Zhejiang Province were recruited to investigate the general information, intention to seek medical advice and satisfaction for health services in primary medical institutions through WeChat. Logistic regression was performed to analyze the influencing factors of the intention and the satisfaction. Importance matrix was used to analyze the key drivers of the satisfaction.
Results:
Among the 620 people surveyed, with a response rate of 93.37%, 142 (22.90%) chose primary medical institutions for advice. Actually 516 (83.23%) people went to primary medical institutions last year, and 384 ( 74.42% ) of them were satisfied with the health services. The results of multivariate logistic regression analysis showed that the people aged 18-25 years who were under the new rural cooperative medical care system ( OR=3.062, 95%CI: 1.745-5.373 ) and who had records in community health centers ( OR=0.547, 95%CI: 0.308-0.970 ) were more likely to go to primary medical institutions for medical advice; the ability of doctors ( OR=1.478, 95%CI:1.168-1.871 ) ,the drug notification by medical staff ( OR=1.308, 95%CI: 1.065-1.606 ) , routine examination items ( OR=1.523, 95%CI: 1.227-1.889 ) , the ways of payment ( OR=1.168, 95%CI: 1.017-1.340 ) , the comfort of environment ( OR=1.785, 95%CI: 1.437-2.219 ) and the bulletin boards of health knowledge ( OR=1.302, 95%CI: 1.086-1.561 ) were associated with the satisfaction. The results of importance matrix analysis showed that the ability of doctors and routine examination items were the priorities to improve, followed by the drug notification by medical staff; the comfort of environment had competitive advantages; the ways of payment and the bulletin boards of health knowledge needed to be further analyzed.
Conclusions
The 18-25-year-old people in Zhejiang Province were less intended to seek medical advice in primary medical institutions, which was associated with the type of medical insurance and records in community health centers. They were satisfied with the health services, the ability of doctors and routine examination items were the key drivers.
