Objective To compare the efficacy of oral rehydration salts(ORS),health education and autonomic nervous activity training with health education and autonomic nervous activity training on children with postural orthostatic tachycardia syndrome (POTS).Methods Fifty-two children with POTS based on head-up test or head-up tilt test were divided into ORS treatment group and conventional treatment group.ORS treatment group included 33 children,and they received ORS and health education and autonomic nervous activity training therapy.Conventional treatment group included 19 children who received health education and autonomic nervous activity training therapy only.Telephone follow-ups were made after the therapy for 1-3 months.The contents of follow-up were the compliance of ORS treatment,the implementation of health education and POTS related symptom frequency.Results 1.The compliance of doctor's advice in ORS treatment group was better than that in the conventional treatment group.2.There was no significant difference in the symptom scores before therapy between ORS treatment group and conventional treatment group [(6 ± 3) scores in ORS treatment group vs (5 ± 3) scores in conventional treatment group,t =0.799,P ＞ 0.05].After 1 to 3 months therapy,the symptom scores were significantly lowered in both groups.The symptom scores in ORS treatment group was lower than those of the conventional treatment group[(2 ± 1) scores in ORS treatment group vs(3 ± 1)scores in conventional treatment,t =-2.189,P ＜ 0.05].3.If the therapy was determined to be effective when the symptom scores decreased by at least 2 scores,the effective rate in ORS treatment group was significantly higher than that of the conventional treatment group(78.8％ in ORS treatment group vs 42.1％ in conventional treatment group,x2 =7.169,P ＜ 0.01).Conclusions The efficacy of ORS,health education and autonomic nervous activity training therapy is better than that of the health education and autonomic nervous activity training therapy only in POTS children.

OBJECTIVE:To probe into the integrity of package insert for 75 kinds of commonly used antiinfective agents for injection in our hospital and to provide reference for rational use of antiinfective agents for injection. METHODS:According to Drug Description Specification and Management Regulation for Drug Description and Label,the terms included in package insert for antiinfective agents for injection were analyzed statistically. RESULTS:The package inserts for 75 kinds of antiinfective agents for injection were enrolled. The proportion of integral items were high while that of some terms related to clinic were low such as dosage and usage,medication for children,over dosage and skin test. The descriptions of PK,pharmacology,toxicdogy, ADR,et al. were very simple and different. CONCLUSION:It is suggested that items about over dosage and medication for special population should be detailed as well as usage so that package insert can guide rational use of drugs in the clinic.

AIM: To analyze and summarize the effect of glaucoma trabeculectomy in the department of ophthalmology in basic hospital.
METHODS: Postoperative intraocular pressure ( IOP ) , filtering bleb and complications of 316 cases (405 eyes) of patients with glaucoma after trabeculectomy were analyzed.
RESULTS: After follow- up 12mo, 76. 5% IOP was controlled in normal level. 42. 5% was filtration bleb typeⅠ, 33. 1% typeII, 14. 6% in typeⅢand 9. 9% in typeⅣ. Intraoperative complication rate was 2. 5%, that was 31.4% at postoperative early stage ( before discharge ) , and 6. 7% at postoperative long - term ( 6mo after discharge) .
CONCLUSION:Trabeculectomy for glaucoma can better solve the problem of high IOP. It is more mature in primary hospitals, but there are still a variety of intraoperative and postoperative complications.

To study the clinical features, diagnosis, and treatment of SCN8 A-related infantile spasm, one 21-month-boy identified a de novo mutation of SCN8 A-related infantile spasm was admitted to West China Second University Hospital, Sichuan University in September 2019 and was enrolled as a research subject.The clinical manifestation and diagnosis process were analyzed by carrying out the retrospective analysis method.This case is the first report on SCN8 A-related infantile spasm in China.This child had hiatal hernia, which has never been reported in SCN8 A gene mutation people.The boy shows marked developmental regression after the onset of seizures at 8-month-old, and a variety of antiepileptic drugs are ineffective.Recently, seizure types have changed into infantile spasm.Levetiracetam was stopped, and provided adrenocorticotropic hormone (ACTH). After treatment, the spasm was relieved.Hiatal hernia may be a phenotype of SCN8 A gene mutation.Sodium channel blockers display high efficacy in SCN8 A-related epilepsy.ACTH therapy for SCN8 A-related infantile spasm is effective.

The oil content and fatty acid composition of Ganoderma lucidum collected from different producing areas, varieties, tissue types and growth periods were measured and analyzed. The results showed that the oil content was 23. 61%-34.17% in different domestic producing areas of China; the oil content of fruiting bodies from major varieties cultured in Zhejiang province were 0.81%-1.87%, wall-unbroken spores were 0.07%-0.24%, wall-broken spores were 27.54%-34.17%, so the oil content of wall-unbroken spores were much higher than fruiting bodies, and wall-breaking treatment would increase the oil extraction rate 150-340 times. G. lucidum spores oil was mainly composed of unsaturated fatty acid composition. oleic acid and linoleic content were 53.26%-58.16% and 10.69%-16.87% respectively. Fatty acid composition ratio of spores and fruiting bodies were significantly different by PLS-DA. Determining the composition of fatty acid, especially the content of oleic acid, stearic acid and palmitic acid, could identify the tissue types of G. lucidum products' sources. In addition, the study result showed that the spores and fruiting bodies collected in the first year contained richer oil and fatty acid than second year's samples from the same variety of G. lucidum.

Objective:To study the in vitro and in vivo transdermal enhancement of one kind of arginine oligomer-chitosan ( CS-R9). Methods: In vitro mouse skin as the barrier, Franz diffusion cells were used to study the transdermal property of tinidazole ( TNZ) solution in vitro enhanced by CS-R9 using TNZ solution as the negative control and TNZ solution with Azone as the positive control. The rats were randomly divided into three groups, TNZ solution group ( the negative group) , TNZ solution with Azone group (the positive group) and TNZ solution with CS-R9 group. At the predetermined time intervals, 0. 5 ml blood was withdrawn from the rats and TNZ concentration was detected by HPLC to evaluate the enhancement of CS-R9 on TNZ in vivo. Results:Compared with the negative group, CS-R9 had significant enhancement on TNZ trandermal penetration in vitro(P <0.05), and showed no significant difference with Azone (P>0. 05). The in vivo results showed CS-R9 exhibited similar transdermal enhancement on TNZ as Azone at the same concentration (P>0. 05), and CS-R9 had sustalned-release property. Conclusion: CS-R9 has promising transdermal en-hancement on TNZ, which is valuable to be studied further.
