Objective To observe the effect of early intervention on the oligodendrocyte-myelin glycoprotein(OMgp) mRNA expression of brain injury neonatal rats caused by intrauterine infection.Methods 1.Twenty-eight Wistar pregnant rats were randomly divided into 2 groups:lipopolysaccharide(LPS)-treated group and saline control group.Pregnant rats were consecutively injected with LPS (450 ?g?kg-1) or saline on the 18th gestation age.After birth,the placentas were taken out and made HE staining to observe intrauterine infection.2.Thirty neonatal rats in the saline control group and 55 rats in the LPS-treated group were randomly selected which were divided into intervention group (n=25) and no-intervention group (n=25).The second post-natal day (P2) rats in intervention group were treated by early touch and enriched environment.The neonatal rats in the no-intervention group and saline control group were fed in a routine way.Five cases of P1 rats were selected respectively from the LPS-treated group and saline control group,and brain tissue pathological section was made to observe the condition of brain injury.3.Five cases of P1,P3,P7,P28 and P42 rats were selected from the saline control group,intervention group and no-intervention group to detect the OMgp mRNA expression levels by using the real time polymerase chain reaction me-thod.Results 1.There were a great number of neurophilic granulocytes in the placentas in the LPS-treated group.2.Brain tissue pathological of P1 in the saline control group had complete substantia alba structure,ordered disposition and lightly stained clear chromatospherite.While in the LPS-treated group, there existed brain tissue looseness,colloid cell aggregation and oligodendrocyte cytoreduction in the position of substantia alba,callositas and capsula interna.Intraventricular hemorrhage,substantia alba blood vessel dilatation and blood capillary angiorrhexis and hemorrhage could also be found.3.There was a higher increase in OMgp mRNA expressions of brain tissue in the LPS-treated group at P1,P3,P7,P28,P42 than those in the saline control group (Pa

Abstract: Objective To analyze the recent cluster outbreaks of imported malaria and explore the risks, challenges and countermeasures for dealing with such events during malaria post-elimination era of malaria, and to provide reference for effectively addressing the risks and consolidating the achievements of malaria elimination. Methods The individual malaria case data from "The Information System for Infectious Disease Surveillance" and "The Information System For Parasitic Diseases Prevention And Control" were collected,and the diagnosis classification, infection source, time and space distribution of cases were analyzed. Results From January 1 to August 11, 2022, a total of 429 malaria cases were reported nationwide, an 18.9% decrease compared to the same period last year (529 cases), all of which were imported cases. The overall weekly trend of the outbreak remained stable, but since Week 31 (July 25-31), there has been a significant increase in the number of cases, with a peak on August 5. From July 25 to August 11, 2022, a total of 162 malaria cases were reported nationwide, up 315.4% from 39 cases in the same period last year, accounting for 37.8% of the total cases up to August 11, 2022. The main source of imported infections was Guinea (95 cases, 58.6%), with most cases reported in Longgang District, Shenzhen City, Guangdong Province (30 cases), Shilin County, Kunming City, Yunnan Province (21 cases), Chaoyang District, Beijing (11 cases), and Xiaoshan District, Hangzhou City, Zhejiang Province (7 cases). Conclusions Due to the concentration of returnees to China, several entry port cities simultaneously experienced cluster outbreaks of imported malaria, which brought immense pressure and challenges to local medical and health institutions. Health facilities at all levels need to maintain high vigilance and sensitivity, be well prepared, and avoid death and secondary transmission caused by imported cases.

Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

OBJECTIVETo investigate the early clinical effects and radiological outcome of dynamic cervical implant (DCI) internal fixation in treating cervical spondylosis, and evaluate its safety and efficiency.
METHODSFrom June 2009 to December 2011, 19 patients with cervical spondylosis correspond to the indication of DCI internal fixation in the study, including 5 cases of cervical spondylotic myelopathy and 14 cases of cervical spondylotic radiculopathy. There were 8 males and 11 females, aged from 35 to 54 years with a mean of 43.2 years. Pathological segments included C3,4 in 1 case, C4,5 in 6, C5,6 in 6, C6,7 in 4, C3,4 and C5,6, C6,7 in 2. All patients were treated with anterior discectomy and decompression and DCI internal fixation, meanwhile, 2 cases of them with anterior cervical corpectomy and fusion plate fixation. Clinical evaluation included Modified Japanese orthopedics association (mJOA), neck disability index (NDI), visual analogue scale (VAS) score and patient satisfaction index (PSI) at pre-operation and final follow-up. Radiographic evaluation included flexion/extension lateral view at operative level and adjacent segment. The adjacent level degeneration was analyzed according to Miyazaki classification on MRI images.
RESULTSAll patients were followed up from 12 to 42 months with an average of 19.8 months. Preoperative mJOA score was 13.6±1.1 and at final follow-up was 16.3±1.2 with improvement rate of 85.0%. Preoperative VAS,NDI was 6.6± 1.4, 17.1±7.4 and at final follow-up was 1.4±0.8, 6.1±3.9, respectively; there was statistical significance in all above-mentioned results between preoperative and final follow-up (P<0.05). Preoperative ROM at operation level was (7.6±1.9)° and final follow-up was (7.8+2.1)°; preoperative ROM at C2-C7 was (38.6±7.2)° and final follow-up was (39.9±6.4)°; there was no statistical significance in all above-mentioned results between preoperative and final follow-up (P>0.05). Preoperative DHI at operation level was (6.3±1.1) mm and final follow-up was (7.1±0.8) mm, there was statistical significance in DHI between preoperative and final follow-up (P<0.05). No heterotopic ossification was found. All patients followed up MRI, degeneration of 3 segments aggravated 1 degree in 38 adjacent segments, without clinical symptom.
CONCLUSIONTreatment of cervical spondylosis with dynamic cervical implant can got satisfactory outcome in early follow-up. Activity of operative segment obtain reservation in some degree. The incidence of adjacent segment degeneration is lower and no adjacent segment disease occur. Nevertheless a longer follow-up time should be needed to assess the long term functionality of the DCI and the influence on adjacent levels.

Racemic (±)-F18 (10-chloromethyl-11-demethyl-12-oxo-calanolide A), an analog of nature product (+)-calanolide A, is a new anti-HIV-1 nonnucleoside reverse transcript inhibitor (NNRTI). A successful enantioseparation of (±)-F18 offering (R)-F18 and (S)-F18 was achieved by a chiral stationary phase prepared HPLC. Their absolute configurations were determined by measurement of their electronic circular dichroisms combined with modem quantum-chemical calculations. Further investigation revealed that (R)-F18 and (S)-F18 shared a similar anti-HIV activities, however, (R)-F18 was more potent than (S)-F18 against wild-type virus, K101E mutation and P225H mutation pseudoviruses.
