Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

This article reported a typical case of paroxysmal kinesigenic dyskinesia(PKD).The patient was a 26-year-old female with a medical history of 10 years.The patient manifested as paroxysmal choreoathetosis of the limb and head triggered by sudden movement in a quiet state,without sensory aura.The symptoms resolved spontaneously after tens of seconds.She was conscious during and between attacks,had a clear family history and a normal neurological examination.No abnormalities were found in brain magnetic resonance image and electroencephalogram.Genetic test showed a frame-shift mutation of c.776del in PRRT2 gene of the proband and her father with similar phenotype.The patient was diagnosed with PKD according to the diagnostic criteria for PKD.The symptoms were significantly relieved after one month of oxcarbazepine treatment with good prognosis.PKD is a rare movement disorder.The patient has typical symptoms,and the mutation site has not been reported in the Human Gene Mutation Database.Therefore,this article enriched the pathogenic gene mutation spectrum of PKD,provided a basis for genetic counseling of PKD and increased the awareness of this rare disease among physicians.

[Abstract] Objective To explore the relationship between supratentorial area (STA), posterior fossa area (PFA) and intracranial area (ICA) of normal adult Tibetans with age and gender. Methods The subjects of this study were native Tibetan adults living in Lhasa. Totally 158 sample populations were between the ages of 20 and 59 years, with an average age (36. 60 ± 10. 75) years, including 64 males and 94 females. Siemens MAGNETOM ESSENZA 1. 5T magnetic resonance scanner was used to scan with 3D-fSPGR sequence, and the images obtained by scanning were stored in DICOM format and imported into 3D Medical medical image processing software, and region of interest was delineated by using the software’s own toolkit. STA, PFA and ICA were measured on T1WI mid-sagittal imaging, and the ratios of PFA / STA, STA / ICA and PFA / ICA were calculated. In order to eliminate the influence of individual differences in skull size on brain structure, this paper corrected the STA and PFA with the same level of ICA, and obtained the relativity of supratentorial area (RSTA) and relativity of posterior fossa area (RPFA). Results The STA was (127. 91 ± 9. 84) cm

The COVID-19 pandemic is still ongoing in the world, the risk of COVID-19 spread from other countries or in the country will exist for a long term in China. In the routine prevention and control phase, a number of local COVID-19 epidemics have occurred in China, most COVID-19 cases were sporadic ones, but a few case clusters or outbreaks were reported. Winter and spring were the seasons with high incidences of the epidemics; border and port cities had higher risk for outbreaks. Active surveillance in key populations was an effective way for the early detection of the epidemics. Through a series of comprehensive prevention and control measures, including mass nucleic acid screening, close contact tracing and isolation, classified management of areas and groups at risk, wider social distancing and strict travel management, the local COVID-19 epidemics have been quickly and effectively controlled. The experiences obtained in the control of the local epidemics would benefit the routine prevention and control of COVID-19 in China. The occurrence of a series of COVID-19 case clusters or outbreaks has revealed the weakness or deficiencies in the COVID-19 prevention and control in China, so this paper suggests some measures for the improvement of the future prevention and control of COVID-19.

Six new tirucallane-type triterpenoids (1-6), along with ten known triterpenoids, were isolated from methylene chloride extract of the resin of Boswellia carterii Birdw. By the application of the comprehensive spectroscopic data, the structures of the compounds were clarified. The experimental electronic circular dichroism spectra were compared with those calculated, which allowed to assign the absolute configurations. Compounds 5 and 6 possesed a 2, 3-seco tirucallane-type triterpenoid skeleton, which were first reported. Their inhibitory activity against NO formation in LPS-activated BV-2 cells were evaluated. Compound 9 showed appreciable inhibitory effect, with an IC

In recent years， with the change in life style， social environment， and national childbearing policy， the proportion of high-risk pregnant women has increased significantly， triggering the spectrum of obstetric diseases to constantly change， which has brought new challenges to the diagnosis and treatment of obstetrics. Traditional Chinese medicine （TCM） has been proved effective in dealing with a variety of obstetric diseases， and various treatment methods are available， which can serve as alternative means for solving refractory obstetric diseases. However， most obstetric clinicians are currently less aware of the therapeutic effects of TCM， which has significantly hindered its participation in clinical treatment. Therefore， the China Association of Chinese Medicine （CACM） organized the outstanding young obstetricians of TCM and western medicine to discuss 15 obstetric diseases responding specifically to TCM or integrated TCM and western medicine， including hyperemesis gravidarum， threatened abortion， ectopic gestation， cough during pregnancy， pregnancy-induced hypertension syndrome， maternal-fetal ABO incompatibility， postpartum hypogalactia， residual pregnancy tissue in uterine cavity， puerperal infection， pantalgia after childbirth， hematoma/undesirable healing after caesarean section， postpartum urinary retention， ileus after cesarean section， pelvic floor dysfunction， and postnatal depression. The suggestions for their treatment with TCM or integrated TCM and western medicine were also proposed， aiming to provide patients with effective and personalized treatments in clinical practice and improve the diagnosis and treatment effects of obstetric diseases， thus benefiting the public. At the same time， more obstetrical clinicians are expected to understand the therapeutic effects and advantages of TCM and draw on the strengths of both TCM and western， thereby promoting the establishment of an obstetric diagnosis and treatment system with Chinese characteristics.

Objective:To investigate the association between serum trace elements and dyslipidemia in Pudong New Area. Methods:A community-based cross-sectional study was carried out. A stratified， cluster sampling approach was used for sampling. In total 1 814 community residents aged above 35 years old were recruited in Pudong New Area， Shanghai. A face-to-face investigation was conducted and blood samples were collected. Serum levels of 16 trace elements， including boron， vanadium， chromium， manganese， iron， cobalt， nickel， copper， zinc， arsenic， selenium， strontium， molybdenum， tin， antimony， and barium were measured by inductively coupled plasma mass spectrometry （ICP-MS）. The relationship between serum trace elements and dyslipidemia was analyzed with single and multiple Logistic regression models. Results:Prevalence of dyslipidemia is higher among participants of more than 45 years old with high BMI， hypertension or diabetes．Serum iron leveled the highest， followed by copper， zinc， selenium， strontium， boron and other trace elements. After adjusting for potential confounders， the odds ratios of dyslipidemia associated with the highest quartile of trace elements concentrations were 1.41 （95%CI： 1.12-1.78）， 0.77 （95%CI： 0.61-0.96）， 1.65 （95%CI： 1.31-2.09）， 1.27 （95%CI： 1.02-1.58）， and 1.32 （95%CI： 1.06-1.66） for chromium， cobalt， zinc， arsenic， and tin， respectively， compared with that associated with the other three quartiles. Conclusion:Some serum trace elements are potentially associated with dyslipidemia in community residents.

Inductively coupled plasma mass spectrometry (ICP-MS) was applied to this study to detect heavy metal contents in Coptidis Rhizoma from different habitats, for a comprehensive understanding of heavy metal residues in Coptidis Rhizoma. Decocting method and artificial gastrointestinal digestion model were used to determine transfer rates of heavy metals in assessment of health risk of heavy metals using the target hazard quotient (THQ) developed by the US EPA (1989). The results showed that excess rates of Cu, Pb, As, Cd and Hg of 17 batches of Coptidis Rhizoma were 0, 12%, 0, 0 and 0, respectively, under the ISO international standard of Chinese medicine-Chinese herbal medicine heavy metal. The transfer rates of Cu, Pb, As, Cd and Hg were 3.63%, 1.69%, 37.17%, 20.86% and 0 in decoction solution, respectively, and 59.15%, 29.98%, 67.55%, 104.59% and 0 in artificial gastrointestinal solution, respectively. The values of THQ under the two ways of administration in adults and children were 0.001 0, 0.005 3 and 0.000 7, 0.003 6, respectively, and the maximum residue limits (MRL) of heavy metals in Coptidis Rhizoma were higher than the contents of samples in this study. The research showed that the contents of heavy metals in Coptidis Rhizoma were in the safe ranges with no obvious risks to human body, indicating that the excessive of heavy metals in Coptidis Rhizoma might be attributed to the unduly strict standard. The contents of heavy metals in Coptidis Rhizoma of different habitats was estimated for health risks using international risk assessment model, which provides a reference for establishment of heavy metal standards in Coptidis Rhizoma.

Objective: To compare the clinical effect of a novel disposable circumcision device Ring with that of conventional circumcision in the treatment of redundant prepuce and phimosis. METHODS: Totally, 750 patients with redundant prepuce or phimosis underwent Ring circumcision (group A, n = 450) or conventional circumcision (group B, n = 300). We recorded the operation time, intraoperative blood loss, Visual Analogue Scale (VAS) intraoperative pain scores, postoperative complications, wound healing time, and patients' satisfaction with postoperative penile appearance, followed by comparison of the collected data between the two groups of patients. RESULTS: All the operations were successfully completed. Group A, as compared with B, showed significantly shorter operation time (［3.78 ± 0.42］ vs ［26.24 ± 3.99］ min, P <0.05), less intraoperative blood loss (［2.39 ± 1.01］ vs ［10.80 ± 3.57］ ml, P <0.05), lower pain scores intraoperatively (0.14 ± 0.36 vs 2.30 ± 1.46, P <0.05), 6 hours postoperatively (0.32 ± 0.78 vs 3.03 ± 1.56, P <0.05) and at the ring removal (3.35 ± 1.42 vs 2.78 ± 1.43, P <0.05), shorter wound healing time (［7.61 ± 1.60］ vs ［8.57 ± 1.37］ d, P <0.05), higher satisfaction with postoperative penile appearance (97.8% ［440/450］ vs 86% ［258/300］, P <0.05), and lower incidence of postoperative bleeding or hematoma (0.89% ［4/450］ vs 3% ［9/300］, P <0.05). No statistically significant differences were observed between groups A and B in the nocturnal pain score before the ring removal (1.45±1.02 vs 1.38 ± 0.92, P >0.05) or the postoperative incidence rate of edema (0.89% ［4/450］ vs 2.33% ［7/300］, P >0.05). There were no significant postoperative infections or delayed incision healing except for 1 case of wound dehiscence in each group. CONCLUSIONS Ring circumcision, with its advantages of shorter operation time, less blood loss and pain, higher safety, and better postoperative penile appearance, is easily accepted by the patients and deserves wide clinical application.

OBJECTIVETo investigate the risk factors of the serious complications related with double-J ureteral stent placement following percutaneous nephrolithotomy (PCNL).

METHODSClinical data were reviewed for 272 patients treated with PCNL and indwelling double-J stents between January, 2014 and April, 2016. The risk factors of serious complications were identified using univariate and multivariate logistic regression analysis.

RESULTSSerious complications of double-J ureteral stenting occurred in 63 patients (23.1%). Univariate and multivariate logistic regression analysis indicated that the ureter abnormalities (β=1.735, P=0.000, OR=5.670), stent indwelling duration (β=1.206, P=0.028, OR=3.340), gender (β=0.895, P=0.016, OR=2.446), preoperative urinary tract infection (β=0.849, P=0.020 , OR=2.338) and stent size (β=0.847, P=0.011, OR=2.333) were all risk factors of serious complications related with the procedure.

CONCLUSIONMale patients are exposed to a higher risk of serious complications following PCNL. Effective management of urinary tract infection and choice of appropriate stent size in cases of ureteral abnormalities help to reduce these complications. The double-J stent should be withdrawn as soon as possible in patients with good postoperative recovery.
