OBJECTIVES: To study the difference in intestinal flora between children with focal epilepsy and healthy children and the change in intestinal flora after treatment in children with epilepsy. METHODS: A total of 10 children with newly diagnosed focal epilepsy were recruited as the case group and were all treated with oxcarbazepine alone. Their clinical data were recorded. Fecal specimens before treatment and after 3 months of treatment were collected. Fourteen aged-matched healthy children were recruited as the control group. Total bacterial DNA was extracted from the fecal specimens for 16S rDNA sequencing and bioinformatics analysis. RESULTS: After 3 months of carbamazepine treatment, the seizure frequency was reduced by >50% in the case group. At the phylum level, the abundance of Actinobacteria in the case group before treatment was significantly higher than that in the control group (P<0.05), and it was reduced after treatment (P<0.05). At the genus level, the abundances of Escherichia/Shigella, Streptococcus, Collinsella, and Megamonas in the case group before treatment were significantly higher than those in the control group (P<0.05), and the abundances of these bacteria decreased significantly after treatment (P<0.05). CONCLUSIONS There is a significant difference in intestinal flora between children with focal epilepsy and healthy children. Oxcarbazepine can significantly improve the symptoms and intestinal flora in children with epilepsy.

Galangal (Alpinia officinaruim Hance) is the rhizome of the perennial herb belonging to Zingiberaceae family. There are many active components in galangal, such as volatile oil, flavonoids, terpenoids, phenylpropanoids and glycosides, among which the content of volatile oil is higher. The bioactivities of galangal volatile oil on health effect includesanti-inflammatory, anti-hypertension, anti-oxidation and prevention of cardiovascular diseases. Cardiovascular disease (CVD) is a kind of diseases related to circulatory system, which is also called circulatory system diseases. Over the past decade, the number of people dying from CVD has increased by 12.5％ worldwide, and it is now the leading cause of human death worldwide. Studies have shown that galangal volatile oil has good pharmacological effects in treating CVD. ① Regulation of glucose and lipid metabolism: studies have found that abnormal lipid metabolism can lead to obesity, diabetes, CVD and other diseases. The serum total triglyceride (TG) content in liver and serum will increase in patients with abnormal fat metabolism. The results showed that the volatile oil of galangal could increase the excretion of neutral cholesterol, significantly reduce liver TG and serum TG, and thus regulate glucose and lipid metabo?lism, prevent lipid deposition and prevent CVD. ② Improving insulin resistance (IR): inhibition of inflammatory cytokines such as IL-1, IL-6 activation and expression of TNF-α, improves IR, thereby protecting myocardium from IR-mediated damage. Through the establishment of endothelial cell injury model induced by high glucose in vitro, it was found that the volatile oil of galangal can significantly reduce the secretion of pro-inflammatory cytokines TNF-αand IL-8, and inhib?it the expression of ICAM-1 and VCAM-1 induced by high glucose, suggesting that it has protective effect on endothelial dysfunction and inflammation induced by high glucose.③Regulate blood oxygenation:during acute myocardial hypoxia, the activity of free radical scavenging system is decreased, and oxygen free radicals are produced in large quantity, which reacts with unsaturated fatty acids on the cell membrane and forms lipid peroxidation, resulting in myocardial structural damage. The results showed that the water extract of Galangal could reduce the content of MDA in blood and protect the SOD activity of ischemic and hypoxic myocardium.④ Protective effect of vascular endothelial cells (ES):ES injury is the pathological basis of some cardiovascular diseases. The results showed that the volatile oil of galangal had a protective effect on ES apoptosis. Compared with the morphology and activity of ES treated with oxidized LDL, galan?gal volatile oil could ameliorate these morphological changes and improve cell viability. ⑤ Antiplatelet agglutination:inhibit platelet aggregation and thromboxane release, improve blood circulation, and have obvious anti-thrombotic effect, which has a good effect on the treatment and prevention of cardiovascular diseases. The results showed that the volatile oil of galangal had inhibitory effect on platelet aggregation and anticoagulant effect. In conclusion, the volatile oil of galangal can be used to prevent and treat cardiovascular diseases. Based on the mechanism of CVD, this study summa?rized the role of the essential oil of Alpinia officinaruim in CVD, providing basis for the clinical application of alpiniaoffici?nalis essential oil in the prevention and treatment of CVD and the development of new drugs.

OBJECTIVE: To establish a screening model for females of reproductive age carrying Duchenne muscular dystrophy (DMD) variants based on a current community health examination platform. METHODS: A total of 61 870 participants were recruited between October 2017 and October 2019. Serum creatine kinase (CK) was measured with a Roche Cobasc 701/702 using an enzymatic rate method. Genetic testing was offered to those with a CK level of ≥ 200 U/L. For carriers of DMD variants, genetic counseling and follow up were provided. RESULTS: For the 61 870 females participating in the program, 1078 were found with raised serum CK (≥ 200 U/L), of which 618 (57.33%) accepted CK re-measurement after at least a two-week interval. One hundred and twenty cases were found with sustained serum CK elevation, of which 6 were confirmed to be definite DMD carriers regardless of family history. Genetic testing was provided to 33 females with a family history for DMD, and 13 were determined as definite carriers. An affected fetus was detected by prenatal diagnosis. After genetic counseling, the parents had opted induced abortion. CONCLUSION Large-scale DMD carrier screening through a three-step approach based on the current community health examination platform is both feasible and cost effective.

OBJECTIVETo investigate the role and significance of FHIT genes depletion, p53 overexpression and HPV16/18 infection in cervical intraepithelial neoplasia (CIN) and cervical carcinoma (CC).

METHODSTumor samples taken from 52 cases of CIN and 69 cases of CC were processed by immunohistochemistry (SP) to determine the expression of FHIT genes and p53 protein, by in situ hybridization to detect HPV16/18 infection, and were compared with those in 18 cases of normal cervical tissues as control.

RESULTS(1) The FHIT expression was positive in normal cervical tissue with no depletion occurred, and was 30.8% in CIN. It was significantly higher in CIN III and carcinoma groups than that in normal and CIN I/II groups (P < 0.01). The depleted expression of FHIT in infiltrating cervical carcinoma group was 66.7% (46/69), significantly higher than that in normal and CIN groups (P < 0.01). Along with the decreasing of cell differentiation, the negative rate of FHIT raised. (2) The positive expression of p53 in CC group was 56.5% (39/69) and the HPV16/18 was 84.1% (58/69), both higher than that in CIN and normal groups (P < 0.05). (3) In CIN and CC groups, the positive rate of p53 in cases with positive or negative FHIT expression was similar (P > 0.05). (4) There is a negative correlation between FHIT and p53 expression. The rate of HPV16/18 infection in the depleted expression of FHIT group was significantly higher than that in FIHT normal expression group (P < 0.01).

CONCLUSION(1) The FHIT-depletion is related with cervical carcinogenesis. It may be used as a marker to serve mass screening of CIN-high risk subjects and diagnostic indicator for early cervical carcinoma. (2) Depleted expression of FHIT is frequently associated with p53 over-expression in CIN and CC subjects, but there is no direct correlation between them. (3) HPV16/18 infection may probably be the common cause leading to altered FHIT and p53 expression.

To analyze and identify the constituents in rat plasma after oral administration of the active fraction of Corydalis yanhusuo, a LC-MS/MS method was established. The constituents absorbed into blood, their original crude drugs and their metabolites were identified either by comparing the retention time and mass spectrometry data with that of reference compounds or by mass spectrometry analysis and retrieving the reference literatures. Nine species are the original form in Corydalis yanhusuo, moreover, some metabolites in blood identified as glucuronide were found. The constituents absorbed into blood and the possible metabolites which demonstrate to originate from the active fraction of Corydalis yanhusuo are responsible for the observed efficacy. Its serum pharmacochemistry should be subjected to complete investigation so as to illuminate the pharmacology and active mechanism of the active fraction of Corydalis yanhusuo.

OBJECTIVE: To present the surgical outcomes of advanced epithelial ovarian cancer (AEOC) since the implementation of a personalized approach and to validate multiple predictive models for R0 resection. METHODS: Personalized strategies included: 1) Non-invasive model: preoperative clinico-radiological assessment according to Suidan criteria with a predictive score for all individuals. Patients with a score 0–2 were recommended for primary debulking surgery (PDS, group A), or otherwise were counseled on the choices of PDS, neoadjuvant chemotherapy (NAC, group B) or staging laparoscopy (S-LPS). 2) Minimally invasive model: S-LPS with a predictive index value (PIV) according to Fagotti. Individuals with a PIV < 8 underwent PDS (group C) or otherwise received NAC (group D). Intraoperative assessment (with Eisenkop, peritoneal cancer index [PCI], and Aletti scores) and surgical results were prospectively collected. RESULTS: Between September 2015 and August 2017, 161 pathologically confirmed epithelial ovarian cancer patients were included. A total of 52 (32.3%) patients had a predictive score of 0–2, and 109 (67.7%) patients had a score ≥ 3. Among these individuals, 41 (25.5%) patients received S-LPS. Finally, 110 (68.3%) patients underwent PDS (A+C), and 51 (31.7%) patients received NAC (B+D). The R0 resection rates in PDS and NAC patients were 56.4% and 60.8%, respectively. The area under the curve (AUC) of Suidan criteria was 0.548 for group (A+C). The AUC of Fagotti score was 0.702 for group C. The AUC of Eisenkop, PCI, and Aletti scores were 0.808, 0.797, and 0.524, respectively. CONCLUSION: The Suidan criteria were not effective in these AEOC patients. S-LPS was helpful in decision-making for PDS and should be endorsed in the future.

Objective To observe the clinical efficacy of self-prescribed Guchong Decoction combined with Ferroids for the treatment of iron deficiency anemia (IDA)patients with unconsolidation of thoroughfare and conception vessels. Methods A total of 70 IDA patients with unconsolidation of thoroughfare and conception vessels were randomized into treatment group and control group,35 cases in each group. The control group was given oral use of Ferroids, and the treatment group was treated with self-prescribed Guchong Decoction combined with Ferroids. One month constituted a treatment course,and both groups were treated for 2 courses. Before and after treatment,we compared the parameters of blood routine test for red blood cells(RBC),hemoglobin (HGB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC),white blood cells(WBC)and platelets,as well as reticulocytes(Ret)and iron metabolism indexes including serum iron(SI),serum ferritin(SF),and total iron-binding capacity(TIBC). The adverse reaction was monitored during the treatment. After treatment,both western medicine clinical efficacy and traditional Chinese medicine (TCM)syndrome clinical efficacy of the two groups were evaluated. A 3-month follow-up was carried out after treatment to evaluate the recurrence rate. Results(1)Drop-out occurred in one case from the treatment group and in 2 cases from the control group because of short-term medication suspension.(2)After treatment for 2 months, western medicine clinical cure rate of the treatment group was 82.4％ and that of the control group was 60.6％, and TCM syndrome clinical cure rate of the treatment group was 94.1％ and that of the control group was 51.5％,the difference being significant(P < 0.05 or P < 0.01).(3)The levels of RBC,HGB,Ret, MCV, MCH, MCHC, and WBC of the two groups were obviously increased after treatment (P < 0.01), and PLT level was markedly decreased (P < 0.01)as compared with those before treatment,but the inter-group differences after treatment were insignificant (P > 0.05). (4)After treatment,iron metabolism indexes of SF and SI of the two groups were significantly increased (P < 0.01), and TIBC of the treatment group was significantly decreased (P < 0.01). The treatment group had stronger effect on increasing SF and SI and on decreasing TIBC than the control group (P < 0.05 or P < 0.01). (5)The incidence of adverse reaction and the recurrence rate in the treatment group were lower than those of the control group,the difference being significant (P< 0.01). Conclusion Guchong Decoction combined with Ferroids is effective for the treatment of IDA with unconsolidation of thoroughfare and conception vessels through relieving symptoms rapidly, reducing gastrointestinal adverse reaction,and decreasing recurrent rate.

OBJECTIVE: To investigate the health status of workers exposed to 7-aminocephalosporanic acid( 7-ACA) and6-aminopenicillanic acid( 6-APA) in an antibiotics enterprise. METHODS: Using simple random sampling method,207 workers exposed to 7-ACA and 6-APA from an antibiotic production enterprise were selected as the exposed group,and 162 workers with no dust exposure history from the same antibiotic production enterprise were selected as control group. Health examinations were performed. The health status of the workers were analyzed. RESULTS: The detection of symptoms( chest distress,shortness of breath,cough,wheezing,itchy skin) and allergic diseases( bronchial asthma,allergic rhinitis,allergic dermatitis) in exposed group were higher than those in control group( P < 0. 05). The lung function indexes such as forced vital capacity( FVC),forced expiratory volume in first second( FEV1) and FEV1/ FVC in the exposed group were lower than those in control group( P < 0. 05). There was no significant difference in the lung function indexes,respiratory and skin allergy symptoms,and allergic diseases between 7-ACA subgroup and 6-APA subgroup( P < 0. 017).The incidence of bronchial asthma,allergic rhinitis had statistical differences in the length of dust exposure in service workers( P < 0. 05). CONCLUSION: Workers exposed to 7-ACA and 6-APA have a high occurrence rate of respiratory symptoms. These workers also suffered from occupational diseases such as bronchial asthma,allergic rhinitis and others.
