Objective To evaluate and monitor the efifcacy of GnRH analogs (GnRHa) therapy. Methods Thirty girls with central precocious puberty diagnosied by LHRH stimulation test were treated with GnRHa for 6-24 months. The LHRH stimula-tion test were performed again at 3 months after initiation of therapy and then every 6 months during treatment. The relationship of peark LH and clinical suppressing pubertal (including Turner stage, bone age, grwoth speed) were compared. The monitor effect of peak LH to efifcacy of GnRHa were eveluated. Results Ninety LHRH stimulation tests were performed, only 7 cases were found to have clinical pubertal development. After 6 months treatment, the base LH level of thirty girls (0.48±0.20) IU/L was signiifcantly lower than that before the treatment (0.75±0.35 IU/L) (P=0.000). The correlation coefifcient between base LH and peak LH was 0.62. The best correlation between clinical suppressing pubertal and LHRH stimulation test was achieved when peak LH was less than 2 IU/L (85.7%sensitivity, 100%speciifcity). Conclusions Base LH value can be used in preliminary as-sessment of the efifcacy of GnRHa therapy for girls with central precocious puberty. The peak LH less than 2 IU/L can be as the indicator of treatment efifcacy.
3. Effects of electroacupuncture combined with passive stretch exercise on disused muscle atrophy and expression of skeletal troponin in mice
Acupuncture Research 2020;45(9):720-725
OBJECTIVE: To observe the efficacy of electroacupuncture (EA) plus passive stretch exercise in the treatment of disused atrophy of gastrocnemius and soleus muscles in mice. METHODS: Fifty C57BL/6 mice were randomly and equally divided into 5 groups: blank control, model, passive stretch exercise (exercise), EA and EA+exercise groups. The muscular atrophy model was established by fixing the gastrocnemius and soleus muscles with plaster immobilization (by putting the right leg into a plastic vial and then twining the vial with medical plaster bandage from the ankle upwards to the thigh and groin to maintain the knee-joint flexion and ankle joint plantar flexion for 7 days). EA (2 Hz/100 Hz, 1 mA)was applied to bilateral "Zusanli"(ST36) for 10 min, once a day for 4 weeks. For mice with the passive exercise, the plastic vial was removed first, followed by pulling out the hindleg to seize the toes to stretch them until the right hindleg is fully extended, then, pushed the leg towards the body. The procedures were repeated once again and again for 10 min. The exercise was conducted once daily, for 4 weeks. The cross-sectional area of fast and slow muscle fibers of the soleus and gastrocnemius was measured under electronic microscope after ATPase histochemical stain and the expression of slow skeletal muscle troponin (TNNI1) and fast skeletal muscle troponin (TNNI2) in the soleus and gastrocnemius was detected by Western blot. RESULTS: Compared with the blank control group, the cross-sectional areas of the fast and slow muscle fibers of the soleus and gastrocnemius muscles were significantly decreased in the model group (P<0.05, P<0.01). Following the interventions, the cross-sectional areas of the fast and slow muscle fibers of soleus muscle in the EA+exercise group, and those of the fast and slow muscle fibers of the gastrocnemius muscle in the EA and EA+exercise groups, and the expression levels of TNNI1 and TNNI2 proteins in the gastrocnemius muscle of the EA+exercise group were significantly increased in comparison with the model group (P<0.05, P<0.01). CONCLUSION: EA combined with passive stretch exercise can promote the recovery of the soleus and gastrocnemius muscles in disused muscle atrophy mice, which may be related to its effect in up-regulating the expression of TNNI1 and TNNI2 proteins.

To establish a UPLC-MS/MS method for the simultaneous determination of geniposide, genipin 1-O-beta-D-gentiobioside and geniposidic acid in rat brains and study the brain pharmacokinetics of the three iridoid glycosides in stroke rat after the oral administration of Xingnaojing. In this experiment, brain samples were precipitated with protein for twice. Acquity BEH C18 column was adopted, with acetonitrile-0.1% formic acid-water as the mobile phase for gradient elution. ESI source was adopted for mass spectra; multiple reaction monitoring (MRM) was conducted to detect negative ions. The time for sample analysis was 3.5 min. the results showed good linear relations among the three iridoid glycosides, with the extraction recovery between 99.6% and 114.3%, good intra- and inter-day precisions and accuracies and stability in line with the requirements. The t1/2 and MRT in the three components were similar in brains of stroke rats. Geniposide and genipin 1-O-beta-D-gentiobioside showed double peaks; where as geniposidic acid showed a single peak. In conclusion, the method is so specific, sensitive, accurate and reliable that it can be used to study the brain pharmacokinetics of Xingnaojing oral preparation.

Objective To know the quality of iodized salt and the current situation of the salt coverage in Tibet,and to provide scientific basis for proposing proper prevention and control measures to Iodine dificiency disorders(IDD). Methods In 2008, according to the "Sampling Methods of the Main Products in the Salt Industry",one batch fifteen salt samples were collected in iodized salt processing factory in Tibet. Five townships were chosen in each county based on 5 different directions of east, south, west, north and center. If the monitoring county has less than five townships, then all of the townships were sampled. In each township, four villages were selected withrandom sampling and importance sampling. In each township, 15 households were selected for salt collection. Results A batch of 15 salt samples in a salt processing plant were tested, and all of them were qualified with salt iodine(34.6±1.58) mg/kg. A total of 21 107 edible salt samples were tested, and 11 203 of them were qualified iodized salt. These results meant that the provincial iodized salt coverage rate was 53.08%. Shannan iodized salt coverage rate was 94.31% (3395/3600) which was the highest in Tibet. Those of Nagqu, Changdu, Ngari were lower, they were 29.84% (897/3006), 24.94% (823/3300) and 17.08% (205/1200), respectively. Conclusions The quality of iodized salt in Tibet is up to the national standard, but the coverage rate of iodized salt is very low.We suggest that the strategy should be carried out according to the national overall program strategy and supplement iodized oil capsule for special groups.
