Objective:To discuss the clinical efficacy of recombinant human growth hormone(rhGH)in the treatment of the pediatric patients with growth hormone deficiency(GHD)and idiopathic short stature(ISS),and to clarify its clinical application value in the pediatric patients with short stature of different etiologies.Methods:The clinical data of 132 children with short stature who treated with rhGH from January 2018 to January 2023 were collected.They were divided into GHD group(n=70)and ISS group(n=62)based on different etiologies.The bone age,target height(TH),body mass index(BMI),height standard deviation score(HtSDS),changes in height standard deviation scores(ΔHtSDS)before treatment and 6 months after treatment,and growth velocity(GV)of the pediatric patients were calculated.Propensity score matching(PSM)and inverse probability of treatment weighting(IPTW)were used to balance the confounding factors between the pediatric patients in two groups and the efficacy and safety of the pediatric patients in two groups were evaluated.Results:There were significant differences in whether children were full-term,bone age,bone age maturity,and TH of the pediatric patients between two groups(P<0.05).Compared with before treatment,the height and HtSDS of the pediatric patients in both GHD and ISS groups were significantly increased after treated for 6 months(P<0.05).Before matched by PSM,there were significant differences in full-term,bone age,bone age maturity,and TH of the pediatric patients between two groups(P<0.05).After matched by PSM,there were no significant differences in gender,region,term birth status,mode of delivery,feeding method,age,bone age,height,BMI,TH,and pretreatment HtSDS of the pediatric patients between two groups(P>0.05);the standardized mean difference(SMD)differences of covariates except for region were<0.2.After weighted by IPTW,there were no significant differences in gender,region,term birth status,mode of delivery,feeding method,age,bone age,height,BMI,TH,and pretreatment HtSDS of the pediatric patients between two groups(P>0.05);all SMD of covariates except for term birth status were<0.2.Before balancing covariates,after meatched by PSM matching,and after weighted by IPTW weighting compared with GHD group,the GV and ΔHtSDS of the pediatric patients in ISS group were slightly increased,but the difference was not significant(P>0.05).In terms of adverse reactions,2 cases(2.68%)of fasting hyperglycemia and 7 cases(10.00%)of hypothyroidism occurred in GHD group;3 cases(4.84%)of fasting hyperglycemia and 2 cases(3.23%)of hypothyroidism occurred in ISS group.Conclusion:rhGH can promote the height increase in the patients with GHD and ISS,and there is no significant difference in the height-increasing efficacy between GHD and ISS children.The incidence of adverse reactions is relatively low during treatment,indicating good overall safety.

This study aims to assess the methodological and reporting quality of animal experimental studies on the treatment of cervical radiculopathy(CR) with traditional Chinese medicine(TCM), analyze the deficiencies during the experimental process, and develop the methods to enhance the quality of such studies. The related articles were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science. The methodological quality and reporting quality of the included studies were evaluated according to the risk of bias tool of the Systematic Review Centre for Laboratory Animal Experimentation(SYRCLE) and the Animal Research: Reporting of in vivo Experiments(ARRIVE) 2.0 guidelines, respectively. A total of 4 086 articles were initially screened, in which 71 articles met the inclusion criteria. The SYRCLE's risk of bias tool revealed selection bias, performance bias, detection bias, and attrition bias of the included studies. The aspects for improvement were identified in the randomization of animal grouping, experimental implementation and outcome assessment, blinding, reporting baseline characteristics, and handling incomplete data. The essential item assessment of the ARRIVE 2.0 guidelines showed high risks in sample size determination, inclusion and exclusion criteria, randomization, blinding, outcome assessment, statistical methods, experimental procedures, and results reporting. Additionally, there were high risks in items recommended by ARRIVE 2.0 guidelines, including study background, ethical statements, animal care, interpretation/scientific implications, generalizability/translation, experimental protocol registration, data availability, and conflict of interest declaration. The existing animal experimental studies about the TCM treatment of CR exhibited methodological and reporting deficiencies. We recommend that researchers refer to the SYRCLE's risk of bias tool and the ARRIVE 2.0 guidelines to rigorously design, implement, and report experiments in a standardized manner, thereby enhancing the scientific, authentic, and reproducible properties of the experiments.

To investigate the relationship between the LNK(SH2B3) gene single nucleotide polymorphism and risk of acute leukemia (AL) in Chinese population.

METHODSThe bone marrow and peripheral blood samples from 31 cases of acute lymphoblastic leukemia, 70 cases of acute myeloid leukemia and 130 healthy persons as the controls were collected. Genotype of LNK SNP Rs3184504(c.784T>C) and Rs78894077(c.724C>T) were determined by PCR-RFLP, and were confirmed by gel electrophoresis and sequencing. The NB4, THP-1 and Raji leukemia cell line models were cultured, the leukemia cell line LNK Rs3184504 and Rs78894077 polymorphism were detected by using direct sequencing.

RESULTSThe CC genotype frequencies of Rs3184504 SNP were higher in ALL and AML patients than those in control (P<0.01), but there was no different between the groups in AML and ALL. The frequency of LNK gene Rs3184504 C allele was higher in AL as compared with control (P<0.01). The LNK gene Rs78894077 locus genotype distribution was not significantly different between the AL and the normal control group (P>0.05). Both Rs3184504 and Rs78894077 sites were detected as CC genotype in NB4, THP-1 and Raji cells.

CONCLUSIONThe persons carrying C allele of LNK gene Rs3184504 are more prone to develop acute leukemia.

OBJECTIVE: To investigate polymorphism distribution of the 5 Y-SNP loci in Jinan Han population, and evaluate their potential in forensic application. METHODS: Genotyping of 5 Y-SNP loci (M89, M9, M122, M134, M95) were executed in the sample of 103 unrelated Chinese male individuals in Jinan Han population by using fragment length discrepant allele specific PCR (FLDAS-PCR). RESULTS: In 5 Y-SNP loci, genetic polymorphism were identified in Jinan Han population, and the ranges of gene diversity(GD) were 0.093 3-0.491 2. Twenty different haplotypes were observed and the haplotypes diversity (HD) was 0.867 9. Six different haplogroups were detected according to international association of Y chromosome nomenclature. CONCLUSION Five Y-SNP loci and their haplogroups in Jinan Han population are highly polymorphic, which can provide more information for the genetic structure analysis and forensic genetics research in the region.

OBJECTIVETo study the prevalence of severe acute respiratory syndrome coronavirus (SARS-CoV) like virus in animals at a live animal market of Guanzhou in 2004 before and after culling of wild animal action taken by the local authority, in order to predict the re-emerging of SARS from animal originals in this region.

METHODSAnimals at live animal market were sampled for rectal and throat swabs in triplicate. A single step realtime reverse transcription-polymerase chain reaction (RT-PCR) diagnostic kit was performed for screening SARS-CoV like virus, the manual nested RT- PCR and DNA sequencing were performed for confirmation. Only specimens which tested positive for both of the N and P genes by nested RT-PCR were scored as positive.

RESULTSIn 31 animals sampled in January 5 2004 before culling of wild animals at Guangdong Province, including 20 cats (Felis catus), 5 red fox (Vulpes vulpes) and 6 Lesser rice field rats (Rattus losea), 8 (25.8%) animals were tested positive for SARS-CoV like virus by RT-PCR methods, of which 4 cats, 3 red fox and one Lesser rice field rats were included. However, two weeks after culling of animals and disinfection of the market were implemented, in 119 animals sampled in January 20 2004, including 6 rabbits (Oryctolagus cuniculus), 13 cats, 46 red jungle fowl (Gallus gallus), 13 spotbill duck (Anas platyrhynchos), 10 greylag goose (Anser anser), 31 Chinese francolin (Franclinus pintadeanus), only rectal swab from one greylag goose was tested positive for SARS-CoV like virus. Furthermore, in 102 animals that including 14 greylag gooses, 3 cats, 5 rabbits, 9 spotbill duck (Anaspoecilorhyncha), 2 Chinese francolin (Franclinus pintadeanus), 8 common pheasant (Phasianus colchicus), 6 pigeons, 9 Chinese muntjac (Muntiacus reevesi), 19 wild boar (Sus scrofa), 16 Lesser rice field rats, 5 dogs, 1 mink (Mustela vison), 3 goats, 2 green peafowl (Pavo muticus) sampled in April, May, June, July, August and November, only rectal swab from one pig was tested positive. However, of 12 and 10 palm civets sampled in November and December including five of which had been at the live animals market for 2 days, none of them was tested positive.

CONCLUSIONThis findings revealed that animals being sampled in April, May, June, July, August and November of 2004, only one rectal swab from a pig was tested positive as SARS-CoV like virus, much lower than the results from the previous year, suggesting that the possibility of re-emerging of human infection from animal origins is low for the winter of 2004-2005.
