OBJECTIVE：To analyze the metabolites of tetrahydroxystilbene glucoside （THSG）and speculate its metabolism pathway in rats. METHODS ：Male SD rats were randomly divided into plasma group （n＝3），urine group （n＝3），bile group （n＝3），and tissue group （n＝9）. Each group was given single dose of THSG 200 mg/kg intragastrically. Plasma samples 10，30 min and 1，1.5，2，4 h after medication ，the unrine 0-6 h after medication ，the bile 0-4 h after medication ，the tissue of heart ， liver，spleen，lung，kidney and stomach 30 min and 1，2 h after medication （3 at each time point ）were collected respectively.After precipitated with methanol ，the metabolites of samples were analyzed and identified by UHPLC-Q-Exactive Orbitrap MS and mass loss filtration （MDF）. Its metabolism pathway was speculated. RESULTS：In the blood ，urine，bile，heart，liver，spleen， lung，kidney，stomach samples ，6，7，11，1，5，1，3，4，4 metabolites were detected ，including two phase Ⅰ（hydrolysis， hydrogenation and hydroxylation ）metabolites，18 phase Ⅱ（glucuronic acid binding and sulfation ）metabolites. There were 12 glucuronic acid binding products. CONCLUSIONS：Most of the metabolites of THSG are found in bile ，mainly glucuronic acid binding products of phase Ⅱ metabolite THSG ； main metabolic pathways involve glucose hydrolysis ， hydrogenation， hydroxylation，glucuronic acid binding and sulfation.

Objective:To analyze the clinical characteristics and experiences in diagnosis and treatment of the patients with novel coronavirus pneumonia (NCP).Methods:Clinical data of 28 patients with NCP in the Fourth People′s Hospital of Nanning from January 22 to February 5 in 2020 were collected. The clinical manifestations, epidemiological history, laboratory tests, imaging examinations and treatments of patients were analyzed retrospectively.Results:The 28 patients with NCP included one mild case, 25 ordinary cases and two severe cases. They were all positive for 2019 novel coronavirus (2019-nCoV) nucleic acid in throat swabs. There were four groups of family clusters. The clinical symptoms were mainly fever and cough, which progressed rapidly in a short period of time. Since the onset of illness, the peak values of axillary temperature of the 28 patients were 36.6 ℃ to 39.5 ℃, while five patients had no fever throughout the course of the disease with the peak temperature ≤37.0 ℃. The illness onset ranged from 1 to 12 days after exposure, and the time from the symptom onset to the positive results of the nucleic acid tests was 0 to 13 days. There were two patients presented with decreased white blood cell counts, five patients with elevated C reactive protein, six patients with abnormal alanine aminotransferase, three patients with abnormal aspartate aminotransferase, 10 patients with elevated creatine kinase, three patients with elevated creatine kinase isoenzyme, four patients with elevated lactate dehydrogenase, and all with normal procalcitonin levels. The chest computed tomography examinations showed that the common features of patients with NCP were ground glass shadows (21 cases), blurred edges (18 cases), speckles and patchy shadows (17 cases), thickening and disorder of some lung textures (seven cases), and visible band shadows (seven cases). Pulmonary lesions often progressed rapidly. A included 11-year-old child was treated with alpha-interferon alone. A total of 27 patients were treated with alpha-interferon inhalation and lopinavir/ritonavir, while four occured withdrawal due to adverse reactions. Up to February 12, nine patients had been cured and discharged who were all ordinary cases, without death cases.Conclusions:The NCP patients mostly present with fever and cough. Pulmonary lesions often progress rapidly. Respiratory pathogen testing should be conducted as early as possible and repeatedly. Disisolation should be cautious for suspected people who are negative for 2019-nCoV nucleic acid in pharynx swabs.

OBJECTIVE：To establ ish the fingerprint of Sojae Semen Nigrum and content determination method of 5 kinds of isoflavones，so as to provide reference for controlling its quality better. METHODS ：HPLC method was adopted to establish the fingerprint and detect the contents of 5 kinds of isoflavones. The determination was performed on Phenomenex C 18 column with mobile phase consisted of acetonitrile- 0.12％ formic acid solution （gradient elution ）at the flow rate of 1 mL/min. The detection wavelength was set at 260 nm；the column temperature was 30 ℃ and sample size was 10 μL. Using daidzin as reference，HPLC fingerprints of 12 batches of samples were determined. The similarity of 12 batches of samples was evaluated by TCM Chromatographic Fingerprint Similarity Evaluation System （2012A） to confirm common peak. Cluster analysis and principal component analysis were performed by using SPSS 20.0 software and SIMCA 13.0 software. RESULTS ：There were 19 common peaks in HPLC fingerprints of 12 batches of samples ，the similarity of which was higher than 0.94. Totally 5 components were identified，such as daidzin ，glycitin，genistin，daidzein，genistein. Cluster analysis showed that 12 batches of Sojae Semen Nigrum were clustered into 2 categories，i.e. S 1-S3 clustered into one category ，and S 4-S12 clustered into the other category. By principal component analysis ，the contribution rates of two principle components were 53.261％ and 40.715％；accumulative contribution rate was 93.976％. The linear range of above 5 components were 5.97-191.00 µg/mL（r＝0.999 9），1.05-33.46 µg/mL（r＝0.999 9）， 8.93-285.61 µg/mL（r＝0.999 5），0.82-26.33 µg/mL（r＝0.999 9），0.93-29.64 µg/mL（r＝0.999 7），respectively. The limits of quantitation were 0.881 1，0.611 6，0.078 6，0.243 3，0.511 6 μg/mL，respectively. The limits of detection were 0.264 3，0.244 7， 0.021 4，0.124 8，0.106 7 μg/mL，respectively. RSDs of precision ，stability，reproducibility and durability tests were all lower than 5％. Recoveries were 95.15％-96.56％（RSD＝0.51％，n＝6），98.52％-103.45％（RSD＝1.88％，n＝6），95.37％-97.91％ （RSD＝0.95％，n＝6），99.75％-102.00％（RSD＝0.78％，n＝6），100.26％-103.65％（RSD＝1.21％，n＝6）. Among 12 batches of Sojae Semen Nigrum ，the contents of above 5 components were 0.178 3-0.265 9，0.021 7-0.096 2，0.288 5-0.597 2，0.014 1- 0.058 8，0.012 9-0.082 9 mg/g. CONCLUSIONS ：Established HPLC fingerprint and content determination method of 5 kinds of isoflavones can be used for quality control of Sojea Semen Nigrum. The Isoflavone components are similar ，but the contents are different among Sojae Semen Nigrum from different producing areas.

Objective:To explore the occurrence of adverse reactions of lopinavir/ritonavir (LPV/r) in the treatment of coronavirus disease 2019 (COVID-19).Methods:The medical records of patients with COVID-19 who received LPV/r treatment in the Fourth People′s Hospital of Nanning from January 24th to February 6th, 2020 were collected and the occurrence of adverse events during the treatment was retrospectively analyzed. According to the 5 principles of adverse drug reaction correlation evaluation proposed in the Handbook of Adverse Drug Reaction Reporting and Monitoring in China, adverse events that were certainly related, probably related, and possibly related to LPV/r were defined as LPV/r-related adverse reactions. The incidence of adverse reactions was calculated and the main clinical manifestations and severity of adverse reactions [grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (life-threatening), and grade 5 (death); grade 3-5 was defined as severe adverse reaction] were analyzed. Results:A total of 28 patients were enrolled in the analysis, including 13 males and 15 females, aged from 18 to 70 years with an average age of 44 years. The courses of treatment with LPV/r of patients ranged from 2 to 12 days, with a median course of 6 days. Of the 28 patients, 18 developed LPV/r related adverse reactions, with an incidence of 64.3%. The LPV/r-related adverse reactions in 18 patients included gastrointestinal reactions in 14 patients (grade 1 in 13 patients and grade 2 in 1 patient), bradycardia in 2 patients (grade 2 in both patients), and acute hemolysis in 1 patient (grade 3), and liver injury in 1 patient (grade 3), and no grade 4 or 5 adverse reactions occurred. The incidence of severe adverse reactions was 7.1%. Thirteen patients with grade 1 adverse reactions did not affect the treatment, and the symptoms were relieved after 2-7 days of continuous medication. LPV/r was discontinued in 5 patients with grade 2 or 3 adverse reactions, 4 of whom received symptomatic treatment, and the symptoms disappeared 2-10 days later.Conclusions:The incidence of adverse reactions in COVID-19 patients treated with LPV/r in our hospital was 64.3%. LPV/r mainly leads to mild gastrointestinal reactions and can also lead to bradycardia, acute hemolysis, and liver injury. Blood routine, liver function, and electrocardiogram need to be monitored during the treatment.

Autophagy, a cellular housekeeping process, is indispensable to controlling the homeostasis of cytoplasm by removing unused proteins and damaged cell organelles. This process involves different types of human diseases, including cancers, neurodegenerative diseases and infectious diseases. Neurodegeneration is a critical pathological process of many eye diseases, such as glaucoma and age-related macular degeneration. The retina and all intraocular cells are constantly exposed to environmental stress and injuries, including oxidative stress and starvation, which lead to autophagy. Autophagy promotes cell survival through the recycling of metabolic precursors, or promotes cell death if autophagy is over-active. Additionally, autophagy and apoptosis have been shown to be harmonious or contrasting, depending on different experimental contexts. All of this contributes to the pathogenesis of many diseases. This paper reviews the mechanisms and regulation involved in autophagy, current understandings of neuronal autophagy in glaucoma and retina and strategies for therapeutic modulation.

Objective To observe the clinical efficacy of sulfonic acid L-amlodipine and its influence on vascular endothelial function in treatment of primary hypertension.Methods Two hundred primary hypertension patients(hypertension group) were divided into amlodipine group and telmisartan group by random digits table method with 100 cases each.The patients of amlodipine group were given the sulfonic acid L-amlodipine treatment,while the patients of telmisartan group were given the telmisartan treatment.The change of systolic blood pressure (SBP),diastolic blood pressure(DBP),nitric oxide (NO),endothelin (ET)-1 and blood lipid before and after treatment,and the adverse reaction were observed continuously for 4 weeks.Also 80 cases of healthy people (control group) were included as a comparative study.ResultsBefore treatment,the lipid levels,blood pressure,NO,ET-1 of hypertension group showed significant difference compared with those of control group (P ＜0.05).The effective rate of amlodipine group and telmisartan group was 97.0％(97/100) and 88.0％(88/100) respectively,and there was significant difference between two groups (x2 =5.838,P ＜ 0.05).After treatment,DBP and SBP of amlodipine group and telmisartan group significantly improved,the difference was significant compared with that before treatment [(77.93 ±24.74) mm Hg (1 mm Hg =0.133 kPa) vs.(103.37 ±34.46) mm Hg,(113.83 ±36.14) mm Hg vs.(167.74 ± 55.91) mm Hg and (85.93 ± 27.28) mm Hg vs.(104.23 ± 34.74) mm Hg,(135.93 ± 43.15)mm Hg vs.(164.57 ±54.86) mm Hg] (P ＜0.05).The blood pressure of amlodipine group meliorated more significantly,and the difference was significant compared with that of telmisartan group (P ＜ 0.05).NO and ET-1 of amlodipine group basically reached normal levels,and the difference was significantly compared with that of telmisartan group [(70.28 ±22.31) μmol/L vs.(50.97 ± 16.99) μmol/L,(60.93 ± 19.34)μ mol/L vs.(51.15 ± 17.05) μ mol/L and (52.69 ± 16.73) ng/L vs.(69.38 ± 23.13) ng/L,(65.71 ± 20.86)ng/L vs.(71.58 ± 23.86) ng/L] (P ＜ 0.05).The adverse reaction was not observed during treatment.Conclusions The clinical efficacy of sulfonic acid L-amlodipine on vascular endothelial function in treatment of primary hypertension is obvious and safe,which could improve the endothelial dysfunction.So this method is worthy of popularizing.

Objective To explore the influence factors of survival quality in cardiac intervention patients of different age.Methods 96 patients with routine cardiac interventional surgery were divided into three groups by age(the juvenile group,the middle-aged group,the elderly group).All the patients were surveyed by the Quality of life scale(SAQ)and questionnaire sheet of the general condition of patients 24h before treatment,3 months after treatment,respectively.The serum biochemical indicators were also detected,and the multivariate analysis was teken by the non-conditional logistic regression analysis.Results The differences of the average score of SAQ in the patients of three groups before and after treatment were statistically significant(all P＜0.05).Multivariate analysis showed that TC and LDL were independent risk factors affecting the quality of life in juvenile patients;the history of hypertension,smoking history,TC,LDL were independent risk factors affecting the quality of life in middle-aged patients,and HDL was the protective factor;the history of hypertension,history of diabetes,history of smoking,TG,TC and LDL were independent risk factors that affected the quality of life in elderly patients,and HDL was the protective factor.Conclusion TheThe survival quality of cardiac intervention patients of different age was influenced by TC and LDL,while HDL is the protective factor;adult patients was also impacted by the history of hypertension,history of diabetes,smoking history.

ObjectiveTo study the relation between premature and cerebral palsy(CP).MethodsTo sample all the children between the age of 1 to 6 years old for investigating CP situation in Nanning city, Heng county and Qinbei region of Qinzhou city (once named Qinzhou county ) from May to December, 1998 by qualified pediatricians.ResultsThe total investigating cases were 150,806,in which diagnosed CP were 193 cases and the incidence of CP was 1.28‰. Among them, premature infants were 872 and diagnosed CP were 46,the incidence of CP was 52.75‰ in this group. While term laboring infants were 149,934 with CP 142 and the incidence of CP was 0.95‰. The difference between two groups was very significant(P<0.001).The shorter the gestational weeks were, the higher the incidence of the CP was. Among 46 premature infants with CP, there were 18 cases' mothers(26 person times) involved in abnormal pregnancy and delivery history, accounted for 39.1%, while 36 with pregnancy complications(78.3%). There were 23 cases (30 person times) suffered from the disease during neonate, accounted for 50%.ConclusionThe premature delivery is a risk factor associated with childhood CP.
