Objective To investigate the bioactivities of controlled release bFGF microspheres (Ms) and their effects on the cultured osteoblasts. Methods The secondary cultured osteoblasts were divided into four groups according to the different ingredients being added to the DMEM culture medium, ie, control group,bFGF group, bFGF-PLGA-Ms group and bFGF-PELA-Ms group. The proliferation of the cultured osteoblasts was measured with cell counting method, MTT method and flow cytometry. The content of bone BGP secreted by osteoblast was also measured with RIA method. Results The in vitro cellular study showed no significant difference in the cell number and cell viability of four groups one day after plate culture.The cell number and cell viability in the bFGF-PLGA -Ms group were more than those in other three groups four and six days after plate culture. The cell number and cell viabilitythose in the bFGF group were more than those in the bFGF-PELA-Ms group six and eight days after plate culture with insignificant difference. The flow cytometrical examination showed that the G 2/M+S percentage in the bFGF group reached the highest two days after plate culture and the G 2/M+S percentage in the bFGF-PLGA-Ms group went the highest four and eight days after plate culture. Among four groups, the content of BGP in the bFGF-PLGA-Ms group was the highest and the bFGF-PELA-Ms group the next. Conclusions The effect of bFGF-PELA-Ms is not satisfactory,as indicates that the manufacturing method needs improving. However,the bFGF-PLGA-Ms can promote the proliferation and differentiation of the osteoblasts through a long period of controlled release of bFGF.

Objective To explore the clinical characteristics and diagnosis of Epstein-Barr(EB) virus encephalitis(EBE) in children. Methods The verification of EBE was based on detection of EBV DNA in cerebrospinal fluid (CSF) by fluorogenic quantitative PCR(FQ-PCR) and Nest-PCR. The clinical and CSF changes of 27 EBE cases and 26 controls were analyzed and compared. Results EB-DNA in CSF by FQ-PCR of 13 cases of EBE was (2.82?2.03)?10 3copies.There was no significant difference in clinical manifestations between EBE and HSE groups, except that WBC in CSF of EBE was lower than those of HSE.Conclusions EBE is not infrequent, about 10 % of encephalitis in children. EBE is always present independently, which is not a complication of infectious mononucleosis(IM).Detection of EBV-DNA in CSF is a sensitive and specific test for diagnosing of EBE. Early treatment may be beneficial to the prognosis of EBE.

Objective: To examine the effect of early comprehensive interventions on the physical growth and nerve development among premature infants, so as to provide insights into the follow-up management of premature infants after discharge from hospital. Methods: A total of 130 premature infants delivered in Shaoxing Municipal Maternal and Child Health Care Hospital from 2019 to 2021 were selected and divided into high- and low-risk groups according to gestational age and birth weight, while 306 full-term normal infants in the same hospital during the study period served as controls. All premature infants were given early comprehensive interventions until age of 12 months, including nutritional support and parental guidance of children's feeding and development, and all normal infants received periodical health checkup according to the basic public health service program. All infants received periodical measurements of height, weight and head circumference, and the 12-month intellectual and motor development ability was measured using the Bayley Scales of Infant Development revised in Chinese cities was used to assess. Infants' physical growth, mental development index (MDI) and motor development index (PDI) were compared among groups. Results: There were 130 premature infants with gestational ages of 28 to 36 weeks and birth weight of 1 200 to 3 440 g, including 79 male infants, and there were 80 infants in the low-risk group and 50 infants in the high-risk group. The full-term infants had a gestational age of 37 to 42 weeks, and birth weights of 2 500 to 4 000 g, including 162 male infants. There were significant differences in height (Wald χ2=28.664, P<0.001) and head circumference growth (Wald χ2=19.312, P=0.013) among the three groups as revealed by the generalized estimating equation; however, no significant differences were seen in the 12-month weight (F=0.639, P=0.528), height (F=1.051, P=0.350) or head circumference (F=0.318, P=0.728) among the three groups. The percentages of abnormal MDI were 2.00%, 0 and 1.31% among the high-risk premature infants, low-risk premature infants and full-term infants at ages of 12 months (χ2=1.319, P=0.517), while the percentages of abnormal PDI were 20.00%, 7.50% and 5.56% among the three groups at ages of 12 months (χ2=12.818, P=0.002). Conclusions Following implementation of early comprehensive interventions, the premature infants have favorable physical growth and comparable MDI with full-term infants; however, a high percentage of abnormal PDI is seen in high-risk premature infants. An improvement in the motor development among high-risk premature infants is recommended to be emphasized during the management of premature infants.

Abstract: Objective　To evaluate the effects of sunitinib on Japanese encephalitis virus (JEV) infection in vitro and vivo. Methods　The 4-week-old BALB/c mice infected with JEV by intraperitoneal injection. The infected mice were treated with sunitinib for 5 days and 10 days respectively. After that, the change of weight and survival rate were evaluated continuously. The viral load variation in mice brain were detected by qRT-PCR. Indirect immunohistochemical staining assay (IFA) was used to detect the number and distribution of CD4+/CD8+T cells in mouse brain. IFA was also used to observe the expression of virus E protein in the brain of mice. Vero cells were infected with JEV in vitro and given a certain concentration of sunitinib to observe the cell survival status. The expression of virus E protein in cells was detected by IFA. Results　Continuous administration of sunitinib significantly improved the survival rate of infected mice. Survival rate and body weight changes showed that the 5-day's administration strategy was significantly better than the 10-day's administration strategy. The treatment of sunitinib decreased the infiltration of CD4+/CD8+T cells in the brain and reduced the changes of vascular sleeve. However, the variation of viral load and E protein expression in brain were not obvious. The cytopathic effect (CPE) of infected Vero cells were slightly relieved after giving sunitinib, and the expression of E protein was also slightly changed. Conclusion　Sunitinib can significantly reduce the mortality of infected mice, and the 5-day's administration strategy is significantly better than the 10-day's administration strategy. Sunitinib decrease T lymphocyte infiltration in brain of mice, relieve the encephalitis symptoms ,and prolonged the life of mice.

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.

Background Cyclosporine A (CsA) is an effective drug to prevent rejection response after penetrating keratoplasty (PKP).Appropriate dosage forms and right administrating route is very important for improving the bioavailability of CsA.Objective This study was to investigate the preventing effect of CsA microspheres via subconjunctive and anterior chamber injection and CsA eye drops on immune rejection after PKP.Methods Sixty eyes of 60 clean adult New Zealand white rabbits served as receipts,and 60 eyes of 30 clean adult pigmented rabbits were used as the donors.The receipts were randomized into the blank control group (only PKP group),subconjunctival CsA injection group,subconjunctival vector injection group,anterior chamber CsA injection group,anterior chamber vector injection group,and 1％ CsA eye drops group.PKP was performed on the all rabbits,and then the CsA microsphere (0.1 ml,12 g/L) or blank microsphere (0.1 ml) were respectively administered in the corresponding groups.The corneal grafts were examined by slit lamp microscope regularly,and rejection index (RI)was calculated based on the corneal opacity,edema and neovascularization.The intraocular pressure (IOP) of operative eyes was measured by Tono-pen tonometer before operation,3 days,1 week,2 weeks,3 weeks,1 month,2 months and 3 months after operation,respectively.Histopathological examination on corneal grafts was performed 1month and 3 months after operation.Results The IOP of all the rabbits lowed after operation,but there was no statistical difference in different time points and various groups (Ftime =29.210,P =0.000; Fgroup =0.254,P =0.938).The grafts of the blank control group,subconjunctival vector injection group and the anterior chamber vector injection group showed varied degrees of corneal opacity and neovascularization 2-3 weeks after operation,and the degree of graft opacity was aggravated obviously in the fourth week,with the RI 8.60±1.52,8.60±0.55 and 8.80±0.84 individually.Neovascularization of the grafts in the subconjunctival CsA injection group,anterior chamber CsA injection group,and 1％ CsA eye drops group was found 3 weeks after operation,and the RI were 4.40±0.89,3.20±0.84 and 3.00±0.71,showing a significantly lower than that of the control groups (P＜0.05).Mild inflammatory response of the grafts was seen in the anterior chamber CsA injection group,but it was lightened over time.The histopathological examination revealed obvious thickening of corneal grafts,neovascularization and infiltration of lots of inflammatory cells in the blank control group,subconjunctival vector injection group and the anterior chamber vector injection group.However,only slight new blood vessels and inflammatory response were seen on the subconjunctival CsA injection group,anterior chamber CsA injection group,and 1％ CsA eye drops group.Conclusions Administration of CsA in different methods can prevent the immune rejection after PKP in rabbit eyes,the effect of giving drugs via anterior chamber injection is better than that via subconjunctive pathyway.

Objective : To evaluate the effects of transcutaneous electrical nerve stimulation ( TENS ) and waterbirth with Doula services on the outcome of delivery. Methods: From July 2018 to December 2019, 150 primiparas in Hangzhou Women's Hospital were randomly divided into three groups: TENS, waterbirth and control groups. They were given TENS, waterbirth and conventional midwifery, accompanied by Doula services. The visual analogue scores ( VAS ) , length of labor stages and neonatal asphyxia were compared. Results: It finally included 45 cases in the TENS group, 45 cases in the waterbirth group and 44 cases in the control group. There were no significant differences in gestational weeks, age, height, weight, fetal biparietal diameter and newborn birth weight among the three groups ( P>0.05 ) . The VAS scores of TENS group and waterbirth group were lower than those of the control group ( P<0.05 ) , but there were no significant differences between the two groups ( P>0.05 ) with the cervix open to 2.5-3 cm, 5-7 cm ( 0.5 hours later ) and 10 cm. There was no interaction between the analgesia methods and cervix diameter ( P>0.05 ) . The duration of the first stage of labor in the TENS group and the waterbirth group was less than that in the control group ( P<0.05 ) , and there was no significant difference between the TENS group and the waterbirth group ( P>0.05 ) . The asphyxia rate of neonates in TENS group, waterbirth group and control group were 2.22%, 2.22% and 4.55%, respectively, with no significant difference ( P>0.05 ) . Conclusion Under Doula services, both TENS and waterbirth can effectively relieve the pain of delivery and shorten the first stage of labor, without obvious differences.

In this paper, the chloroplast psbK-psbI intergenic spacers of 18 species of Dendrobium and their adulterants were amplified and sequenced, and then the sequence characteristics were analyzed. The sequence lengths of chloroplast psbK-psbI regions of Dendrobium ranged from 474 to 513 bp and the GC contents were 25.4%-27.6%. The variable sites were 71 while the informative sites were 46. The inter-specific genetic distances calculated by Kimura 2-parameter (K2P) of Dendrobium were 0.006 1-0.058 1, with an average of 0.028 4. The K2P genetic distances between Dendrobium species and Bulbophyllum odoratissimum were 0.093 2-0.120 4. The NJ tree showed that the Dendrobium species can be easily differentiated from each other and 6 samples of the inspected Dendrobium species were identified successfully through sequencing the psbK-psbI intergenic spacer. Therefore, the chloroplast psbK-psbI intergenic spacer can be used as a candidate marker to identify Dendrobium species and its adulterants.
