OBJECTIVETo observe the clinical efficacy of treating chronic persistent bronchial asthma (CPBA) children with abnormal myocardial enzyme spectrum (AMES) by Yupingfeng Powder (YP) combined routine therapy.
METHODSFrom January 2010 to December 2012, 156 CPBA children patients with AMES were randomly assigned to the treatment group (80 cases) and the control group (76 cases). All patients received routine treatment (inhaled corticosteroids and/or leukotriene regulator). Besides, those in the treatment group took YP. The treatment duration was 3 months. The scores of children asthma control test (C-ACT), pulmonary function (FEV,% and PEF%), myocardial enzyme spectrum were observed before and after treatment, and 3 months before and after treatment. The myocardial enzyme spectrum of 40 healthy children at the baby clinics during the same period were recruited as the control.
RESULTSCompared with the control group, creatine kinase isoenzyme (CK-MB), creatine kinase(CK), and lactate dehydrogenase (LDH) increased in the two treatment groups (P <0.01), but there was no statistical difference in AST (P >0.05). Compared with before treatment in the same group, CK-MB, CK, LDH, and AST decreased in the treatment group after treatment and 3 months after treatment (P <0.01). CK-MB, CK, LDH, and AST decreased in the control group 3 months after treatment (P <0.01, P <0.05).Compared with after treatment, CK decreased in the control group 3 months after treatment (P <0.01). C-ACT score, FEV(1),%, and PEF% all increased in the two groups after treatment and 3 months after treatment (P <0.01, P <0.05). Compared with after treatment in the same group, CK decreased in the control group 3 months after treatment (P <0. 01). Compared with the control group in the same period, post-treatment CK-MB and CK decreased (P <0. 01, P <0. 05), while post-treatment C-ACT score, FEV, %, and PEF% increased (P <0.05) in the treatment group (P <0.05).
CONCLUSIONYP could strengthen specific and non-specific immunity of the organism, and improve clinical symptoms and the level of myocardial enzyme spectrum.

Forest musk deer (Moschus berezovskii), a rare wild medicinal animal, is listed under the category of the state key protected wildlife list of China. Musk, secreted by the musk glands, is with high economic and medicinal value and used as precious traditional medicine in China. In order to meet the needs of musk in Chinese traditional medicine, forest musk deer farming was conducted in 1950s, but the research progress on musk secretion mechanism was slow. Therefore, by reviewing the histological and anatomical structure of forest musk deer musk gland, the relationship between sex hormones and the musk secretion process, and the molecular mechanism of the musk secretion, the existing problems in investigating the musk secretion mechanism were analyzed and the development trends in this field were also discussed, in order to provide a reference for further studies on the musk secretion mechanism and improve musk production of forest musk deer.

OBJECTIVE:
To discuss the efficacy and safety of simultaneous bilateral endoscopic surgery (SBES) for bilateral upper urinary tract calculi, and to summarize the initial experience.
METHODS:
Patients diagnosed with bilateral upper urinary tract calculi who underwent SBES in the Department of Urology, Beijing Chao-Yang Hospital from January 2019 to January 2020 were enrolled retrospectively. The demographic and clinical data of the patients were recorded, and the operation status, stone free rate (SFR) and peri-operative complications were analyzed. The primary end point was SFR, and second end point was peri-operative complications.
RESULTS:
A total of 23 patients underwent SBES, of which SBES was completed in 19 patients (12 males, and 7 females). The mean age was (41.3±12.0) years. Fourteen patients underwent modified supine position surgery and 4 patients in prone split-leg position. There was no statistical difference in the demographic and baseline clinical data of the patients in different positions. One patient underwent right percutaneous nephrolithotomy (PCNL) and left endoscopic combined intra-renal surgery (ECIRS) in the prone split-leg position, while 18 patients received simul-taneous surgery with PCNL and contralateral retrograde intra-renal surgery (RIRS). The mean anesthesia and operation time was (128.7±26.5) min and (70.7±20.3) min, respectively, which was significantly longer in the patients with prone split-leg position than in the patients with modified supine position, anesthesia time in the patients with prone split-leg position and modified supine position: (148.4±20.4) min vs. (121.6±25.3) min, respectively, t=-2.121, P=0.049, while the operation time in the patients with prone split-leg position and modified supine position: (86.4±21.1) min vs. (65.1±17.4) min, respectively, t=-2.222, P=0.040. There was no significant difference between the two groups in indwelling of nephrostomy [prone split-leg position and modified supine position: (2.6±0.9) d vs. (2.1±1.0) d, respectively; t=-0.880, P=0.391] and the length of hospital stay [prone split-leg position and modified supine position: (6.0±2.7) d vs. (5.2±1.8) d, respectively; t=-0.731, P=0.475]. One month after the operation, the SFR was 78.9%, and 3 patients had minor peri-operative complications (Clavien-Dindo grades Ⅰ/Ⅱ) without any serious complications (Clavien-Dindo grades Ⅲ/Ⅳ/Ⅴ).
CONCLUSION
The simultaneous bilateral endoscopic surgery would decrease the operation time and anesthesia exposure under the premise of ensuring the SFR, which is helpful to reduce the risk of peri-operative complications, especially to the patients who can not tolerate the second-stage or long-time operation.
