To compare the chemical change of Paeoniae Radix Alba (PRA) after vinegar-baking processing, as well as the effect of vinegar types exerted on the processing, 1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to investigate the different metabolites between the raw and two vinegar-baked PRA. More than thirty metabolites were identified in the 1H NMR spectrum of PRA, and the multivariate statistical analysis showed that raw and two vinegar-baked PRA could be separated obviously. After vinegar-baking, the contents of isoleucine, lactate, alanine, arginine, albiflorin, and 5-hydroxymethyl furfural (5-HMF) elevated, while those of sucrose, paeoniflorin and its analogues (calculated by benzoate) decreased. The chemical compositions of two vinegar-baked PRA were also different. Shanxi vinegar- baked PRA showed higher levels of leucine, isoleucine, valine, and albiflorin, while rice vinegar-baked PRA contained more sucrose and paeoniflorin's analogues (calculated by benzoate). And the chemical changes in Shanxi vinegar-baked PRA were greater than those of rice vinegar-baked PRA. The results revealed the chemical differences between raw and vinegar-baked PRA, as well as the influence of vinegar type on processing, in a holistic manner, the results obtained suggested that the correlations between the chemical change and the drug action after processing, as well as the vinegar type used in processing, should be further studied.

Food-born trematodes which parasitize liver, lung and intestine cause various trematodes diseases. There are a few common trematodes such as Clonorchis sinensis, Fasciola, Opisthorchis, Paragonimus, and Echinostoma. This review provides recent progress in techniques and methods for their immunodiagnosis. These methods are mainly used to diagnose with excretory-secretary antigen, recombinant antigen and antibodies of hosts, by means of enzyme-linked immunosorbent assay, immunoblotting, immunefluorescence, immunehistochemistry, proteomics and a lateral flow detection system so on. It is beneficial to improve diagnostic and accuracy rates when all this methods are used synthetically.

1H NMR metabonomics approach was used to reveal the chemical difference of urine between patients with Xiao-Chaihu Tang syndrome (XCHTS) and healthy participants (HP). The partial least square method was used to establish a model to distinguish the patients with Xiao-Chaihu-Tang syndrome from the healthy controls. Thirty-four endogenous metabolites were identified in the 1H NMR spectrum, and orthogonal partial least squares discriminant analysis showed the urine of patients with Xiao-Chaihu Tang syndrome and healthy participants could be separated clearly. It is indicated that the metabolic profiling of patients with Xiao-Chaihu Tang syndrome was changed obviously. Fifteen metabolites were found by S-pot of OPLS-DA and VIP value. The contents of leucine, formic acid, glycine, hippuric acid and uracil increased in the urine of patients, while threonine, 2-hydroxyisobutyrate, acetamide, 2-oxoglutarate, citric acid, dimethylamine, malonic acid, betaine, trimethylamine oxide, phenylacetyl glycine, and uridine decreased. These metabolites involve the intestinal microbial balance, energy metabolism and amino acid metabolism pathways, which is related with the major symptom of Xiao-Chaihu Tang syndrome. The patients with Xiao-Chaihu Tang syndrome could be identified and predicted correctly using the established partial least squares model. This study could be served as the basis for the accurate diagnostic and reasonable administration of Xiao-Chaihu-Tang syndrome.

ObjectiveTo explore an appropriate way and its effect on neonatal resuscitation training in Uygur area of Xinjiang, China.MethodsFrom October 2014 to February 2015, obstetricians, neonatologists (pediatricians), midwives and anesthetists from Turpan Region Central Hospital, Turpan City People's Hospital,Aksu Region First People's Hospital and other five hospitals at county level were chosen to attend the training course of neonatal resuscitation. The textbook for the course was Guidelines for Resuscitation which had been translated to Uygur language from English and the class was lead by less than ten Uygur trainees with Mandarin and Uygur when necessary in addressing some difficult or important points. The duration of theoretic courses took 6 h and the operational course took 8 h. Theorectical exam was taken before, immediately after and three months after (before re-training) the training. The accuracy rate was applied to assess the effect of training through evaluation for each resuscitation techniques. Repeated measures analysis of variance andChi-square test were used for statistical analysis.ResultsA total of 220 health care staff were included in the study. The average score of theoretical examination after the training was higher than that before (85.68±8.52 vs 65.37±12.08,t=18.532,P=0.000), and that before re-training was lower than that after training (80.08±12.70 vs 85.68±8.52,t=-4.943,P=0.000). After the training, the proportions of Done in each item, including rapid assessment, preliminary resuscitation, correct positive pressure artificial ventilation, external cardiac massage together with artificial ventilation, proper endotracheal intubation and proper administration of resuscitation drugs, were all higher that those before [72.7%(160/220) vs 1.4%(3/220), 40.0%(88/220) vs 0%(0/220), 15.9%(35/220) vs 0%(0/220), 37.7%(83/220) vs 8.2%(18/220), 51.8%(114/220) vs 5.9%(13/220) and 48.2%(106/220) vs 10.5%(23/220), allP<0.01]. But at the time before re-training, only one proportion ofDone which was higher than those immediately after initial training was proper administration of resuscitation drugs [49.6%(109/220) vs 48.2%(106/220),χ2=9.129,P<0.05].ConclusionBilingual (Mandarin and Uygur) neonatal resuscitation training in Xinjiang minority areas might enhance the recovery skills for local medical personnel.

OBJECTIVE:
To explore the genetic basis for an infant with permanent neonatal diabetes mellitus (PNDM).
METHODS:
Clinical data of the child was collected. Targeted capture-next generation sequencing was carried out to identify the potential variants. Candidate variant was verified by Sanger sequencing of her family members.
RESULTS:
The child was a 4-month-and-26-day female featuring onset of ketoacidosis accompanied with fasting blood glucose of 24.4 mmol/L, positive urine glucose, decreased serum C-peptide, HbA1c of 9.58%, and negative diabetes autoantibody. Genetic testing revealed that she has carried a heterozygous c.314T>G (p.L105R) variant of the INS gene. Sanger sequencing verified that neither of her parents has carried the same variant, which was also unreported in the literature. The variant was classified as likely pathogenic based on the ACMG guidelines.
CONCLUSION
The c.314T>G (P.L105R) variant of the INS gene probably underlay the genetic etiology in this child. Genetic testing should be conducted for children with suspected PNDM for early diagnosis and appropriate treatment.

Objective:To provide molecular evidence for clinical diagnosis and genetic counseling by analyzing the clinical characteristics and identifying the pathogenic genes in a SPONASTRIME-type spondyloepimetaphyseal dysplasia(SEMDSP)family.Methods:Clinical data of the family members was collected and analyzed. Case 2 was identified as the proband for whole-exome sequencing and variant analysis. Suspected variants were validated across family numbers using Sanger sequencing.Results:The two affected individuals in this family, a brother and a sister, both presented as short stature. The initial diagnosis for the sister(case 1)was made at the age of 4 years and 2 months(height: 88.6 cm), and for the brother(case 2)at 4 years and 4 months(height: 81.6 cm). Both individuals exhibited distinctive facial features, including frontal bossing, midface hypoplasia with depressed nasal bridge, upturned nostrils, ocular hypertelorism, and epicanthus, thick hair, short lingual frenulum, stubby fingers and palms, and absence of scoliosis. The parents displayed normal phenotypes. Laboratory tests indicated growth hormone deficiency in both affected individuals. Imaging studies revealed significant bone age delay in case 2, while case 1 showed longitudinal striations at the distal radius but with bone age matching their actual age(5 years and 11 months). Despite receiving recombinant human growth hormone treatment, both patients had inadequate responses. Genetic testing identified compound heterozygous mutations in the TONSL gene shared by the two siblings. These mutations included a paternally inherited c. 1291-14_1291-11delCCTC and a maternally inherited c. 1909_1920delACGCTGCAGCAG. Notably, SEMDSP families have not been reported in China, and the c. 1909_1920delACGCTGCAGCAG mutation is a novel variant.Conclusion:Two patients were diagnosed as spondyloepimetaphyseal dysplasia, SPONASTRIME type, and the compound heterozygous variant was the genetic cause of this family.

Objective:To analyze the clinical and genetic characteristics of five patients with familial male-limited precocious puberty(FMPP).Methods:The clinical data, laboratory and imaging results of the five patients with FMPP were collected. Whole exome sequencing was carried out to identify the potential variants. Suspected variants were verified by Sanger sequencing of family numbers.Results:Of the five patients, four were children and one was an adult. All the four children presented to hospital with premature sexual development at age less than 4 years. Serum testosterone was elevated, luteinizing hormone(LH) and follicle stimulating hormone(FSH) basal values were at prepubertal levels, and gonadotropin-releasing hormone(GnRH) stimulation test suggested peripheral precocious puberty. Genetic analysis revealed the mutations of LHCGR genes in all the five patients. Patients 1, 2, 3, and 4 carried the same heterozygous mutation c. 1713G>C(p.M571I), and the patient 5 carried the c. 1741T>C(p.C581R)variation. The four children were treated with anti-androgen preparations and the third-generation aromatase inhibitors, all of which were effective.Conclusion:The c. 1713G>C mutation of LHCGR gene is a novel one which expands the mutation spectrum of LHCGR gene. Combined treatment with bicaluamide and the third generation aromatase inhibitors can improve clinical symptoms and delay epiphyseal closure in children with FMPP.

Objective:To investigate the clinial phenotype and genetic characteristics of a child with cerebral dysgenesis, neuropathy, ichthyosis, and palmoplantar keratoderma (CEDNIK) syndrome and to improve the clinicians′ understanding of this disease.Methods:Clinical data of the child with CEDNIK syndrome diagnosed in Department of Endocrinology, Genetics and Metabolism, Xi′an Children′s Hospital in June 2020 were collected. Whole exome sequencing was carried out to identify the potential variants of SNAP29 gene. Suspected variants were verified by Sanger sequencing of family numbers. The literature about the cases of CEDNIK syndrome were reviewed.Results:The proband is a boy, who was aged 1 year and 4 months, had the manifestations of psychomotor retardation, microcephaly, feeding difficulties, severe malnutrition, recurrent respiratory tract infection, binocular esotropia, sensorineural deafness, cutaneous ichthyosis and keratosis, left cryptorchidism. Brain magnetic resonance imaging indicated congenital dysplasia. Whole exome sequencing identified a homozygous variant of c.383dupT (p.E129Rfs *5) in the SNAP29 gene of the proband, and the heterozygous variation was observed at the same locus in his parents, which conformed to the autosomal recessive inheritance. This mutataion was determined as a pathogenic mutation according to the guidelines of American College of Medical Genetics and Genomics. Literature retrieval showed currently a total of 29 cases of CEDNIK syndrome were reported, containing 8 types of SNAP29 gene mutation. However, there was no Chinese case reported. And the c.383dupT (p.E129Rfs *5) mutation found in this study was a novel one which had not been reported yet. Conclusion:The phenotype of the proband is generally consistent with the CEDNIK syndrome and the novel c.383dupT (p.E129Rfs *5) mutation of SNAP29 gene is the genetic cause.

OBJECTIVE:
To explore the clinical characteristics and genetic basis of a child with 5α-reductase type 2 deficiency.
METHODS:
Clinical data of the child was retrospectively analyzed. Targeted capture-next generation sequencing and Sanger sequencing were carried out to detect potential variants.
RESULTS:
The patient's main features included micropenis and hypospadia. He was found to harbor compound heterozygous c.680G>A (p.R227Q) and c.3G>T (p.M1I) variants of the SRD5A2 gene. Among these, c.680G>A (p.R227Q) was inherited from his father and was a known pathogenic mutation, while c.3G>T (p.M1I) was inherited from his mother and was unreported previously.
CONCLUSION
The compound heterozygous variants of the SRD5A2 gene probably underlay the disease in this child, who was eventually diagnosed with 5α-reductase 2 deficiency.
