A method for determinations of germanium in garlic was developed by means of acid digestion and extraction under reflux. It obriated not only the volatile loss of Ge but also the loss of volatile Allicin in the Allium sativum, with usual distillation methods. At the same time the sensitivity was remarkably increased under coprecipitation with ferric hydroxide and extraction operation. A good linear relation was obtained in the range of 0-2.0?g Ge. The average recovery of Ge is 90.9%, coefficient of variation is 4.0%, and detection limit in the Allium sativum is 0.14?g. The method is suitable for determination of Ge in other biological samples as well.

AIM : To prepare a phase-specific drug delivery system withfloating and pulsatile release of sinome-nine hydrochloride and evaluate in vitro drug release behavior. METHODS: The floating and pulsatile-release of coat-core tablets were prepared by press-coated technics. The effects of factors influencing release characteristic of the drug were investigated by dissolution test, and to elucidate the mechanism of drug releaseof the tablets with erosion and water-uptake test. RESULTS: The tablets had typical floating and pulsatile release properties with a lag time rapid release. The lag-time was shortened with the increase of expansion ratio of tablet core and rotation speed of stirrer. The lag-time was prolonged with the increase of pH and ionic strength of dissolution media.CONCLUSION: The tablet could float and rapidly release drug at the predetermined time.

ObjectiveTo analyze the seroepidemiologic of Mycoplasma pneumoniae infection and evaluate antibiotics medication of some positive patients by follow-up. Methods Serodia-MycolⅡ particle agglutination assay was used to detect serum antibodies against Mycoplasma pneumoniae in 3 134 clinically suspected infections. Mycoplasma pneumoniae infection was determined and seroepidemiologic was analyzed by results of the test, including positive antibody rates in whole subjects, in male or female groups, in different seasons or age groups as well as in different sources. Evaluate antibiotics medication of some positive patients by follow-up. The average days of medication were counted, different antibiotics medication and medication effect were analyzed. Results In 3 134 serum samples from clinically suspected Mycoplasma pneumoniae infections, 350 ( 11.2％ ) were tested with positive antibodies. The positive antibody rate in female patients was 12. 3％ ( 198/1 604), which was higher than 9. 9％ ( 152/1 530) in males (X2 =4. 58,P ＜0. 05). The peak season was found in the fourth quarter (October-December) with 13.2％ of positive antibody and the highest positive rate (32. 8％, 45/137 ) was found in school aged (5 -9 years old )children. Samples from pediatrics clinic and ward were tested to have highest positive rates ( 27. 9％ and 26. 5％, respectively ), comparing that from other sources. Infection due to Mycoplasma pneumoniae was identified in 28％ (7/25) of community-acquired pneumonia (CAP) patients, which is higher than other diseases. Based on the follow-up of 91 antibody positive patients, between 5 to 120 days ( mean 24. 2 days )were counted from appearance of clinical symptoms to clinic visiting/testing. 71 of 91 (78. 0％ ) patients was medicated with macrolide antibiotics, 4 (4. 4％ ) with quinolones, 4 (4. 4％ ) with cephalosporin, and the rest 12 ( 13.2％ ) patients were medicated with other antibiotics or only symptomatic treatment. The average period of antibiotics medication was between 3 to 21 days (mean 8. 2 days). Medication effect results by follow-up were cure in 35 ( 38. 5％ ), improvement in 50 (54. 9％ ), and poor responses in 6 (6. 6％ ).ConclusionsMycoplasma pneumoniae positive rate in female patients was higher than in males, and peak rate was found in the fourth quarter and in school aged children. Samples from pediatrics clinic and ward were tested to have highest positive rates. Physicians could choose first line antibiotics according to laboratory test results of Mycoplasma pneumoniae, and gain good effect.

Objective:To investigate the clinical efficacy and safety of modified Shaoyao Gancao decoction in the treatment of hyperprolactinemia caused by amisulpride. Methods:Ninety patients with hyperprolactinemia caused by amisulpride who received treatment in Kangci Hospital from June 2018 to October 2019 were included in this study. They were randomly divided into the placebo control, control and observation groups ( n = 30/group). The placebo control group was treated with the decoction with the taste and color (without drug ingredients) similar to that of modified Shaoyao Gancao decoction. The control group was treated with Shaoyao Gancao decoction. The observation group was treated with modified Shaoyao Gancao decoction. All patients were treated for 8 weeks. Clinical efficacy, serum prolactin level and Positive and Negative Syndrome Scale score before and after treatment, Treatment Emergent Symptom Scale score after treatment, glucose and lipid metabolism, liver and kidney function before and after treatment were compared among the three groups. Results:The effective rate in the placebo control, control and observation groups was 90.0% (27/30), 96.7% (29/30) and 100.0% (30/30), respectively, and the difference among the three groups was statistically significant (χ 2 = 7.027, P < 0.05). After treatment, serum prolactin level in the observation group [(48.2 ± 15.7) μg/L] was significantly lower than that in the control group [(52.5 ± 13.7) μg/L] and placebo control group [(57.7 ± 16.9) μg/L, t = 7.134, 7.034, both P < 0.05]. After treatment, Positive and Negative Syndrome Scale score in the observation group [(51.02 ± 3.98) points] was significantly lower than that in the control group [(54.07 ± 4.19) points] and placebo control group [(58.13 ± 4.24) points, t = 5.813, 6.317, both P < 0.05]. After treatment, Treatment Emergent Symptom Scale score in the observation group [(5.2 ± 1.3) points] was significantly higher than that in the control group [(4.9 ± 1.4) points] and placebo control group [(4.4 ± 1.2) points, t = 7.011, 7.231, both P < 0.05]. After treatment, blood glucose, low-density lipoprotein cholesterol, triglyceride, total cholesterol, alanine aminotransferase, aspartate aminotransferase levels in the observation group were significantly lower than those in the placebo control and control groups (all P < 0.05). Serum level of high-density lipoprotein cholesterol in the observation group was significantly higher than that in the placebo control and control groups (both P < 0.05). Conclusion:Modified Shaoyao Gancao decoction is highly effective in the treatment of hyperprolactinemia caused by amisulpride. It can reduce serum prolactin level and has good safety.
