Objective To assess lipid status of pregnant women with GDM based on the lipid reference intervals for pregnant women .Methods Maternal blood and venous cord blood samples were collected in 81 well-controlled GDM mothers and 86 control subjects .The total cholesterol (CHOL) ,trigalloyl glycerol (TRIG) ,high-density lipoprotein cholesterol (HDL) ,low-density lipo-protein cholesterol (LDL) ,apolipoprotein A1 (ApoA) ,apolipoprotein B (ApoB) and lipoprotein (a) levels were measured by auto-matic biochemical analyzer .We used a normal pregnancy specific lipid reference interval (PSR) and normal non-pregnant reference intervals (NPR) respectively to assess the lipid status of pregnant women with GDM .Results Compared with normal control group ,the Apo A ,HDL and LDL levels in GDM group were significantly lower (P<0 .05) .The HDL ,LDL and Lp(a) levels of GDM cord blood were significantly lower (P<0 .05) .The weight of offspring birth of GDM pregnant women with low level HDL was significantly higher (P<0 .05) ,and that of GDM pregnant women with high level LDL offspring birth weight was significantly lower (P<0 .05) .Maternal HDL was not correlated with birth weight (r= -0 .190 ,P=0 .103) .Parent LDH and birth weight was negatively correlated (r= -0 .252 ,P=0 .029) .Conclusion The reference range of normal pregnancy-specific lipid we had estab-lished is more scientific for assessment of blood lipids .

PurposeTo investigate the clinical value of inverted X-ray plain film and MRI examination in the diagnosis of congenital anorectal malformation (CARM). Materials and Methods Thirty-eight cases with operatively proved anorectal malformation were reviewed; inverted X-ray plain film and MRI examination were performed in all patients before surgery. The relationship between the rectum blind side and pubococcygeal line (PC line), and the type of anal atresia was determined, to compare the diagnostic accuracy of inverted plain film with MRI for CARM typing. Results Of all the 38 cases, 19 cases were with low imperforate anus, 8 cases with median imperforate anus, and 11 cases with high imperforate anus. The accuracy rate of inverted X-ray plain film and MRI examination for the diagnosis of CARM typing was 92.1% (35/38) and 97.4% (37/38) respectively, and the difference between them was not statistically significant (χ2=1.37, P>0.05). 7 cases of fistula, 5 cases of spinal cord malformations and 1 case of right kidney agenesis can be clearly demonstrated on MRI. Conclusion Both inverted X-ray plain film and MRI can diagnose the typing of CARM accurately, but MRI is also able to diagnose the fistula, visceral, spinal cord lesion and other abnormalities accompanied with CARM, while reducing the dose of X-ray radiation and damage in children, thus has higher clinical application value compared with inverted X-ray plain film.

Objective To investigate the expression and clinical significance of DJ-1 protein in the endometrial carcinoma and delineate its functional roles in endometrial carcinoma progression.Methods Expression of DJ-1 was examined with immunohistochemical staining of 69 paraffin-embedded endometrial carcinoma samples who underwent surgery at Hunan province Tumor Hospital.Kaplan-Meier analysis was performed to describe the survival curve.Univariate and multivariate analyses were performed with COX proportional hazard model.Results (1) The expression of DJ-1 protein in endometrial carcinoma was significantly higher than that in normal endometrial tissues (P ＜ 0.05).(2) There was positive correlation between the high expression of DJ-1 protein in endometrial carcinoma samples and the pathological grade,the International Federation of Gynecology and Obstetrics (FIGO) stage,depth of myometrial invasion,or lymph node metastasis (P ＜ 0.05).(3) Kaplan-Meier analysis indicated that the cumulative 5-year survival rate in the low-DJ-1 expression group was 80.8％,whereas it was only 51.2％ in the high-DJ-1 expression group (P ＜ O.05).COX analysis indicated that the expression of DJ-1 was not the endometrial carcinoma independent prognostic factors for overall survival time (P ＞ 0.05).Conclusions The high expression of DJ-1 protein in endometrial carcinoma samples demonstrated a significantly positive correlation with the pathological grade,FIGO stage,depth of myometrial invasion,and lymph node metastasis.However,DJ-1 is not enough to be independent prognostic factor for overall survival time.

Biofuels and bio-based chemicals from lignocellulosic biomass are sustainable, making them alternatives to petroleum-derived fuels and chemicals to address the challenges of the shortage of crude oil supply and climate change resulted from the overconsumption of petroleum-based products, particularly in China. However, high cost in liberating sugars from lignocellulosic biomass is still the bottleneck of the commercialization of biofuels and bio-based chemicals. In this article, the major components of cellulases and their synergistic role in the hydrolysis of pre-treated biomass is reviewed, followed by how to evaluate the enzymatic hydrolysis. With the elucidation of the underlying mechanism of the conformations of the enzyme molecules and their effectiveness in attacking cellulose substrate, more efficient enzymes are expected to be developed. Using the high production strain Penicillium decumbens, the on-site production of cellulases for cellulose ethanol production is discussed.

In 2012, USA Food and Drug Administration (FDA) approved 39 new drugs, however, there are only two botanical drugs (one topical and one oral) approved by FDA since the publication of the FDA's industry guidelines for the botanical drug product in June 2004. The approval shows the Western guideline can be used for herbal medicines, authors investigate current regulation on herbal medicine clinical research, identify challenges conducting clinical trials, and seek to produce some guidance for potential investigators and sponsors considering a clinical trial in this area. Key words were formulated for searching on Medline and FDA website to locate relevant regulations for clinical research in herbal medicines to understand current environment for herbal medicine usage and examine the barriers affecting herbal medicine in clinical trials. Authors critically explore case study of the 1st FDA approved botanical drugs, Veregen (sinecatechins), green tea leaves extract, a topical cream for perianal and genital condyloma. In consideration of current regulation environment in USA, based on the findings and analysis through the literature review and Veregen case study, authors produce and propose a Checklist for New Drug Application of Herbal Medicines for potential investigators and sponsors considering in a herbal medicine clinical trial.

The high-content image-based assay is commonly leveraged for identifying the pheno-typic impact of genetic perturbations in biology field.However,a persistent issue remains unsolved during experiments:the interferential technical noises caused by systematic errors(e.g.,tempera-ture,reagent concentration,and well location)are always mixed up with the real biological signals,leading to misinterpretation of any conclusion drawn.Here,we reported a mean teacher-based deep learning model(DeepNoise)that can disentangle biological signals from the experimental noises.Specifically,we aimed to classify the phenotypic impact of 1108 different genetic perturbations screened from 125,510 fluorescent microscopy images,which were totally unrecognizable by the human eye.We validated our model by participating in the Recursion Cellular Image Classification Challenge,and DeepNoise achieved an extremely high classification score(accuracy:99.596％),ranking the 2nd place among 866 participating groups.This promising result indicates the success-ful separation of biological and technical factors,which might help decrease the cost of treatment development and expedite the drug discovery process.The source code of DeepNoise is available at https://github.com/Scu-sen/Recursion-Cellular-Image-Classification-Challenge.

Objective To investigate the influences of maternal gestational diabetes mellitus (GDM) on amino acid levels in neonates.Methods From June 2016 to May 2017,393 pregnancies diagnosed with GDM in Changzhou Maternity and Child Health Care Hospital Affiliated to Nanjing Medical University and 3 924 normal pregnancies were enrolled in this study.Clinical data of the gravidas and their newborns were collected.Heel blood samples were collected at 72 to 96 hours after birth.Tandem mass spectrometry was performed to detect the levels of 11 amino acids including alanine,arginine,citrulline,glycine,leucine/ isoleucine/hydroxyproline,methionine,ornithine,phenylalanine,proline,tyrosine and valine in neonatal heel blood.Differences in amino acid levels between the two groups were compared by t test.Influences of GDM on neonatal amino acid levels were analyzed by multivariate linear regression.Results Compared with the healthy pregnancy group,neonates in the GDM group had higher levels of methionine [(21.01 ±6.30) vs (19.93±6.47) μmol/L,t=3.159,P=0.002] and phenylalanine [(47.19±9.19) vs (45.78±8.58) μ mol/L,t=3.076,P=0.002],but lower levels of alanine [(280.51 ±64.54) vs (290.15±68.40) μ mol/L,t=2.678,P=0.007],proline [(147.64±30.64) vs (152.36±33.57) μ mol/L,t=2.680,P=0.007],tyrosine [(85.21 ±29.50) vs (90.60± 33.32) μ mol/L,t=3.089,P=0.002] and ornithine [(101.22±28.79) vs (105.83±30.10) μmol/L,t=2.906,P=0.004].Multivariate linear regression analysis showed that GDM was responsible for the increase of methionine (β=0.69,95％CI:0.02 to 1.37,P=0.044) and phenylalanine (β=1.60,95％CI:0.69 to 2.51,P=0.001),and the decrease of tyrosine (β=-4.98,95％CI:-8.42 to-1.54,P=0.005) and ornithine (β=-3.16,95％CI:-6.30 to-0.02,P=0.048) in neonates.Conclusions GDM neonates has increased of methionine and phenylalanine levels and decreased tyrosine and omithine levels.

Objective:To discuss outcomes of emergency repairing for Gustilo III B and III C fractures of forearm with complicated tissue defects and the related influence factors.Methods:From January 2014 to Feburary 2022, data of 98 cases of Gustilo III B and III C fractures with large compound defects of soft tissue, blood vessel, bone, tendon or muscle from elbow to wrist were collected. Primary debridement, bone fixation, wound coverage by free flap, bone transfer(or bone cement filling) or dynamic reconstruction of muscle were completed with emergency surgery in Department of Hand and Foot Microsurgery, Xi'an Fengcheng Hospital. Postoperative follow-ups were conducted through outpatient clinic visits, telephone and WeChat reviews. Video clips, questionnaires and the latest information of patients were also analysed. Rank sum test and Chi-square test were used to examine the relationship between independent variables such as general condition, disease condition and surgical procedures of chimeric tissue transfer group and simple flap transfer group, together with dependent variables such as limb salvage, number of surgery, wound healing, function scores, and complications. P<0.05 were further included in the regression equation to discover the relationship between multiple independent variables and dependent variables. Results:Follow-up lasted for 6-96 months, with an average of 71.1 months. In the chimeric group, the limb salvage rate was at 95.1%, with an infection rate of 8.50% and an average number of surgery was 2.13±0.89. In the simple flap transfer group, the limb salvage rate was at 87.5%, with an infection rate of 15.38% and an average number of surgery was 2.62±0.64. The good rate of Anderson score was 65.3% and the average score of Disability of the Arm, Shoulder and Hand(DASH) was 32.9(0-60) points for all the patients. There were significant differences in dependent variables of limb salvage and infection rate between the 2 groups ( P<0.05). Ischemia time and method of bone fixation led to significant differences in number of surgery ( P<0.05). Methods of bone fixation and the types of flap made significant differences in wound healing ( P<0.05). Underlying disease, bonedefect, Gustilo classification and method of bone fixation all contributed to the significant differences in function score ( P<0.05 or P<0.01) . Conclusion:Emergency surgery for repair of serious injury of forearm has a relatively high limb salvage rate and good functional effects. The limb salvage rate is not correlated with independent variables such as severity of injury, Mangledextremity Severity Score (MESS) and ischemia time, while transfer of a simple flap or a chimeric flap is significantly correlated with the limb salvage rate, infection and wound healing. The severity of injury, ischemia time and bone defect are correlated with functional assessment, number of surgery and bone healing.

Objective:To explore the value of Neoseq in screening and diagnosis of neonatal fatty acid oxidation disorders (FAOD).Methods:A retrospective case-control study was conducted on 163 500 live births in Changzhou city from April 2015 to April 2021. The following two models were adopted for FAOD screening and diagnosis. (1) Traditional mode: Heel blood samples were obtained from all subjects for initial screening using tandem mass spectrum (TMS), followed by next-generation sequencing (NGS) and other differential diagnostic testings for those with positive results. (2) Neoseq: Neoseq was performed on the true positive, negative and false positive cases according to the traditional mode screening results. The detection rate, additional discovery, reporting period, and other parameters of the two models for FAOD were described and compared.Results:(1) Detection and diagnosis of FAOD: A total of 18 confirmed cases of FAOD were detected through the traditional model, with an incidence of 1/9 083 in Changzhou city. The positive rate was 0.55% (907/163 500) for initial TMS and 0.04% (73/163 500) for the second. The positive predictive value was 2.0%(18/907), with a false positive rate of 98%(889/907) in the initial screening. (2) The results of Neoseq: ①Pathogenic mutations were detected in 16 of the 18 confirmed cases, and the coincidence rate of mutation sites between the two methods was 16/18. The other two confirmed cases were missed diagnosed by Neoseq, including one β-ketothiolase deficiency with only one detected pathogenic mutation and one medium-chain acyl-CoA dehydrogenase deficiency without any detected pathogenic mutation. ②No pathogenic mutations were detected in the 57 false-positive cases by Neoseq. ③Among the 100 negative cases in initial screening, DUOX2 heterozygous mutation, and MTTL1 hemizygous mutation were detected in one case each. ④The median period of results reporting was 43.5 d (28-104 d) for the traditional mode and 12 d (10-15 d) for the Neoseq mode. Conclusions:Neoseq has a high detection rate for FAOD. Combined with TMS screening, Neoseq reduces the false-positive rate of biochemical screening, rapidly identifies genetic causes by shortening the results waiting time and covers diseases that couldn't be detected by traditional biochemical methods.
