Objective: To investigate the coverage of rotavirus vaccination among children under five years in Xiuzhou District of Jiaxing City, so as to provide insights into rotaviral diarrhea control. Methods: The rotavirus vaccination data of children aged two months to five years were extracted from the vaccination clinics of eight township hospitals and community health service centers through the Zhejiang vaccination information system. The coverage of rotavirus vaccination was analyzed among children with different genders, ages, types of vaccines and doses of vaccination. Results: Totally 32 752 children were included, and the coverage of rotavirus vaccination was 47.09%. The coverage of rotavirus vaccination was significantly higher in boys than in girls ( 47.65% vs. 46.46%, P<0.05 ), and a higher vaccination rate was seen in children with local household registration than in those without ( 56.76% vs. 38.75%, P<0.05 ). The vaccination rates of monovalent and pentavalent rotavirus vaccines were 36.90% and 10.18%, respectively. Totally 26 982 doses of rotavirus vaccines were vaccinated, with a mean dose of ( 0.84±1.02 ) per capita, and the vaccination rates of one, two and three doses were 20.75%, 17.37% and 8.96%, respectively. The median age was 6.00 months ( interquartile range, 3.00 months ) among children vaccinated with the first dose. Conclusions The coverage of rotavirus vaccination and full-dose vaccination are low among children under five in Xiuzhou District, with monovalent rotavirus vaccines predominant. Intensified rotavirus vaccination is therefore recommended.

OBJECTIVETo study the correlation of 1-deoxynojirimycin (DNJ) between Taxilli Herba parasitized in mulberry and its host-plants.

METHODThe contents of DNJ of Taxilli Herba parasitized in mulberry and non-mulberry were determined by RP-HPLC. DNJ was extracted with 0.05 mol x L(-1) HCl, and then detected by fluorescence detector after derivatized with FMOC-Cl at pH 8.0 with borate buffer. The separation was performed on an Agilent C18 (4.6 mm x 250 mm, 5 microm) column with a mobile phase of acetonitrile-0.1% aqueous acetic acid (51: 49) at a flow rate of 1.0 mL x min(-1). The wavelength of fluorescence detector was operated at lambda(EX) = 254 nm and lambda(EM) = 322 nm.

RESULTThe linear range of DNJ was 3.72-37.2 mg x L(-1) (r = 0.999 9). The average recovery was 96.42%. The contents of DNJ in mulberry and Taxilli Herba parasitized in mulberry were 1.39-10.16 mg x g(-1) and 0.46-2.72 mg x g(-1), respectively. However, the contents of DNJ could not be detected in Taxilli Herba parasitized in non mulberry and its host-plants.

CONCLUSIONAs the characteristic constituent of mulberry, DNJ was accumulated in Taxilli Herba This method can be applied to the quality control of Taxilli Herba from mulberry.

Objective To present our experiences of treatment of intraventricular infection complicated with hydrocephalus by neuroendoscopic approach. Methods A retrospective review of clinical data of 27 patients with severe intraventricular infection complicated with hydrocephalus treated under neuroendoscope at our hospitals from January 2011 and December 2014 was performed. All patients were diagnosed by clinical menifestations and cerebrospinal fluid (CSF) analysis, and operations including ventricular drainage, eliminate intraventricular pus, third ventriculostomy and septostomy were done by one senior surgeon. The neuroendoscopic techniques and clinical outcomes were analyzed. Results Preoperative cerebrospinal fluid analysis in all patients presented with decreased glucose level and increased white cell counts up to 1 500 ×106/L. Cerebrospinal fluid glucose levels of 23 patients (85.2%) were higher than 3 mmol/L (reference value: 2.5-4.5 mmol/L) and body temperature of 22 patients (81.4%) returned to normal level in one week after surgery; 24 patients (88.9%) showed improvement in hydrocephalus; death was noted in one patient (0.04% ). Conclusions Neuroendoscopy has great advantage of broad vision. Intraventricular structure and pathology can be clearly observed with neuroendoscopy. Our experience in treating intraventricular infection and hydrocephalus by neuroendoscopic method has great effectiveness.

Glioblastomas remain the most clinically challenging primary brain tumors in adult,which has a dismal prognosis.Glioblastoma carries a dismal prognosis primarily due to its aggressive proliferation in the brain regulated by complex molecular mechanisms.This review will explore the relationship between glioblastoma and both signal transducer and activator of transcription 3 (STAT3) signal pathway,and introduce the inhibition of glioblastoma growth through effectively inhibiting STAT3 signal transduct pathway.Besides,we further discuss the signal pathway related to STAT3.

Objective:To investigate effect of miR-20b on the motor dysfunction after traumatic brain injury (TBI) in mice and the underlying mechanism.Methods:Sixty C57BL/6J mice were divided into sham group, TBI group and TBI+miR-20b Agomir (Agomir-20b) group according to the random number table, with 20 mice per group. A model of severe TBI was induced by controlled cortical impact. After injury, the mice in TBI group were subjected to tail-vein injection of 200 μl Agomir-negative control at dosage of 50 μmol/L and the mice in TBI+Agomir-20b group were subjected to tail-vein injection of 200 μl Agomir-20b at dosage of 50 μmol/L. At days 3 and 7 postinjury, the rate of neuronal apoptosis in the pericontusional region was detected by TUNEL assay, expression levels of apoptosis-related proteins in the pericontusional region were detected by Western blot analysis, including cleaved caspase-3, cleaved poly adenosine diphosphate-ribose polymerases (PARP), B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax), motor function was evaluated by beam walking test, and expression levels of cytokine mRNAs in the pericontusional region were detected by real-time quantitative PCR (RT-qPCR), including interleukin (IL)-1β, IL-6, IL-10, inducible nitric oxide synthase (iNOS), arginase (Arg) and macrophage mannose receptor 1 (CD206).Results:In TUNEL assay, the rate of neuronal apoptosis in sham group was significantly lower than that in TBI group and TBI+Agomir-20b group at days 3 and 7 postinjury (all P<0.01), and there was a significantly lower rate of neuronal apoptosis in TBI+Agomir-20b group as compared with TBI group (all P<0.01). In Western blot analysis, significantly increased levels of cleaved caspase-3, cleaved PARP and Bax proteins and lowered level of Bcl-2 protein were observed in TBI group at days 3 and 7 postinjury as compared with sham group (all P<0.01); similar levels of cleaved caspase-3, cleaved PARP and Bax proteins were found in TBI+Agomir-20b group at days 3 and 7 postinjury as compared with sham group (all P>0.05), and level of Bcl-2 protein in TBI+Agomir-20b group also showed no obvious variation at day 7 postinjury as compared with sham group ( P>0.05) in regardless of a significant reduction at day 3 postinjury ( P<0.01). Significantly increased levels of cleaved caspase-3, cleaved PARP and Bax proteins as well as a significantly reduced level of Bcl-2 protein were found in TBI group at days 3 and 7 postinjury as compared with TBI+Agomir-20b group (all P<0.05 or 0.01). In beam walking test, the latency and foot slip rate in TBI group were significantly higher than those in sham group and TBI+Agomir-20b group at days 3 and 7 postinjury (all P<0.01). In RT-qPCR analysis, levels of IL-1β, IL-6 and iNOS mRNA in TBI group were significantly higher than those in TBI+Agomir-20b group at days 3 and 7 postinjury (all P<0.01), but the two groups were similar in levels of IL-10, Arg and CD206 mRNA (all P>0.05). In comparison with sham group, levels of IL-1β, IL-6, iNOS and IL-10 mRNA in TBI+Agomir-20b group had no obvious change at days 3 and 7 postinjury (all P>0.05); level of Arg mRNA in TBI+Agomir-20b group was significantly increased at days 3 and 7 postinjury (all P<0.01); level of CD206 mRNA in TBI+Agomir-20b group did not change significantly at day 3 postinjury ( P>0.05), but was significantly increased at day 7 postinjury ( P<0.01). Conclusions:miR-20b can obviously inhibit neuronal apoptosis to improve motor function after TBI in mice, for which the underlying mechanism is related to Agomir-20b inhibiting the transformation of microglia to pro-inflammatory M1 type after TBI.

Objective To explore the outcomes and complications of 111 patients with pituitary neoplasms after neuroendoscopic endonasal transsphenoidal surgeries.Methods A retrospective review of clinical and radiographic data of 111 patients (113 procedures),admitted to our hospital from June 2010 to July 2014,was performed.The resection rate,clinical cured rate and complications in pituitary neoplasms of different Knosp classifications were compared.Results Gross total resection (GTR) rate for pituitary neoplasms according to Knosp classification was 97.4％ in grade 0,85.7％ in grade 1,88.7％ in grade 2,51.9％ in grade 3 and 0％ in grade 4,with significant differences (P＜0.05);GTR rate in pituitary neoplasms of grade 3 and 4 was significantly lower than that in pituitary neoplasms of grade 1 and 2 (P＜0.05).Clinical cured rate of the prolactin adenomas of different Knosp grades was significantly different,and that of grade 0 was statistically higher than that of grade 1-4 (P＜0.05).Clinical cured rate of growth hormone adenoma,adeno-corticotrophic stimulating hormone adenoma and mixed-functional adenomas of different grades showed no significant differences (P＞0.05).Chief complaints were improved in 75.0％-91.7％ non-functioning adenomas.Postoperative severe complications included 3 patients (2.7％) with cerebrospinal fluid rhinorrhea,4 (3.5％) intracranial hematoma,1 (0.9％);postoperative mild complications included 3 (2.7％) epistaxis,14 (12.4％) transient diabete insipidus,1 (0.9％) permanent diabetes insipidus and 3 (2.7％) hyponatremia.Mortality was observed in one patient with intracranial hematoma.Conclusions Neurendoscope provides a superior view of the sellar region,and improves the extent of resection of pituitary adenoma especially for those with cavernous sinus invasion;however,blind pursuit of GTR for tumor with Knosp classification greater than grade 3 will increase the risk of severe complications.Safety should always be the priority for a procedure with a long learning curve like neuroendoscopic surgery.Remission of residue tumor can be addressed by subsequent radiotherapy/stereotactic surgery.
