ABSTRACT
Objective@#To study the relationship between human cytomegalovirus (HCMV) envelope glycoprotein gene H and clinical features of children with congenital cytomegalovirus infection.@*Methods@#A cohort study was conducted. Newborns diagnosed with congenital cytomegalovirus infection, hospitalized in the Department of Neonatology and Neonatal Intensive Care Unit (NICU) of the Children′s Hospital, Zhejiang University School of Medicine, were included from July 2013 to December 2015.HCMV-DNA gH typing in urine, sputum or blood was conducted. Patients then were divided into gH1 group and gH2 group according to gH genotypes. Patients′ data during hospitalization in newborn and 3-5 years of follow-up were collected.The relationships between gH genotype and clinical manifestations, laboratory examinations, hearing loss and neurological prognosis were analyzed by chi-square test, t test and non-parametric test.@*Results@#A total of 21 cases were enrolled as congenital HCMV infection and followed-up for 3-5 years. Among them, 14 (67%) were gH1 type and 7 (33%) were gH2 type. No mixed infection was found. In the two groups, there were no significant differences in the ratio of males (9/14 vs. 3/7,P=0.397), or birth weight ((2 609±686) vs. (3 021±451) g, t=-1.436, P=0.167). Gestational age of gH1 group was younger than that of gH2 group (38 (29-40) vs. 39(38-40) weeks, Z=-2.18, P=0.029). Moderate to severe hearing loss detected by neonatal auditory brainstem response were found in 40 ears (20 cases). It was higher in gH1 group than that in gH2 group (4/22 vs.0/18, χ2=5.145, P=0.023). In the imaging examination of the nervous system, the Alarcon score of gH1 group was lower than that of gH2 group (0.4±0.3 vs. 1.3±1.1, t=-2.459,P=0.024).No significant statistical difference was found in the probability of motor or language development lag in gH2 group and gH1 group (4/7 vs.4/14, P=0.346).@*Conclusions@#Compared with gH2 infection, gH1 infection in children has a younger gestational age. The major type of hearing loss in neonatal period is gH1 infection. Children with gH2 congenital infections are more likely to suffer from nervous systems damage.

ABSTRACT
Objective: To understand the combination use and rationality of Chinese patent drugs containing Salvia Miltiorrhiza or its active ingredients and western medicines to provide reference for regulating prescriptions and improving rational drug use level. Methods: The prescriptions of outpatients in our hospital during January 2016 and December 2016 were collected by a retrospective study method, and the ones with the combination use of Chinese patent drugs containing Salvia Miltiorrhiza or its active ingredients and western medicines were analyzed. The rationality of the combination use was analyzed in aspects of physicochemical properties, phar-macological effects, pharmacodynamics and pharmacokinetics. Results: Totally 257 730 prescriptions were examined selectively, and among them, 8 894 were with the combination use of western medicines and Chinese patent medicines containing Salvia Miltiorrhiza or its active ingredients including 1 213 irrational prescriptions (13. 64% ). The irrational prescriptions showed such problems as antago-nism in pharmacologic action causing decreased efficacy (510, 42. 04% ), overlaying in pharmacological effects causing increased effi-cacy (492, 40. 56% ), precipitation because of physical and chemical reactions and chemical taboos (299, 24. 65% ) and reduced bioavailability and affected efficacy due to complex reactions (174, 14. 34% ). Conclusion: The combination use of western medicines and Chinese patent medicines containing Salvia Miltiorrhiza or its active ingredients should be careful to avoid irrational problems. When they are auditing prescriptions and monitoring medication, clinical pharmacists should strengthen intervention of the combination use of Chinese patent medicines and western medicines reasonably combining with physical and chemical properties of medicines, phar-macological effects, pharmacodynamics and other characteristics.
ABSTRACT
Objective To study the removal effect of Moringa seedprotein on turbidity water. Methods The protein of Moringaoleifera seed was extracted by salting out and salting out methodand the protein concentration of Moringa oleifera seed wasdetermined by Coomassie blue staining;The removal effect of Moringa seed protein on turbidity water was determined by coagulation test.The contents of COD, ammonia nitrogen and nitrate nitrogen in the water were determined to determine the effect of Moringa seed protein on water quality. Results The experimental results showed that Moringa oleifera seed protein has good removal effect on high and medium turbidity water, and its removal effect is in a dose - dependent manner.The removal rate of 7 mg/L of Moringa seed protein to high and medium turbidity water reached 92.25 ％ and 64.71 ％ respectively. But the removal efficiency of low turbidity water was less than 7 mg/L, the removal rate of low turbidity water was only 31.91％.The results of determination of COD, ammonia nitrogen and nitrate nitrogen showed that the Moringa seed protein did not increase the content of organic matter in the water while removing turbidity effectively. Conclusion Moringa oleifera seed protein has a certain removal effect on turbidity water, among which the removal effect of high and medium turbidity water is strong, and the removal effect of low turbidity water is poor.Moringa oleifera seed protein had little effect on water quality.
