Objective:To investigate the relationship between protein tyrosine phosphatase non-receptor type 1 (PTPN1) gene polymorphism and the risk of gestational diabetes mellitus (GDM).Methods:In this case-control study, 4 835 pregnant women who delivered from March, 2012 to July, 2014 in the Department of Gynecology and Obstetrics at the First Hospital of Shanxi Medical University were consecutively enrolled. Among them, 789 cases were diagnosed with GDM. A simple random sampling method was used to select 334 pregnant women with GDM as the case group, and 334 healthy pregnant women matched by maternal age, gestation time and residence were set as control. The DNA genotyping was performed in the subjects, and those with genotyping deletions10% were excluded; and finally, 322 and 317 subjects were included in case and control group, respectively. Under the codominant, dominant, recessive, and allelic genetic models, the unconditional logistic regression model was used to check the relationship between 13 candidate single nucleotide polymorphism (snp) loci in PTPN1 gene and the risk of GDM. The Haploview was used to analyze the relationship between haplotypes and risk of GDM, and multiple comparisons were adjusted with the false discovery rate (FDR) method.Results:The age of the 639 pregnant women analyzed in this study was (30.28±4.32) years. The proportions of pre-pregnancy body mass index (BMI)≥24.0 kg/m 2 and having a family history of diabetes were significantly higher in the GDM group compared to those in the control group (29.19% vs 16.72% and 13.04% vs 6.31%, respectively, both P0.05). The rs6096644 locus was positively associated with increased risk of GDM in co-dominant (GG vs AA, OR=2.76, 95% CI: 1.18-6.44) and recessive (GG vs AA+AG, OR=2.78, 95% CI: 1.20-6.46) genetic models (all q0.2). The rs6096655 locus was positively associated with increased risk of GDM in codominant (AA vs GG, OR=5.90, 95% CI: 1.27-27.36) and recessive (AA vs GG+GA, OR=5.50, 95% CI: 1.19-25.38) and alleles (A vs G, OR=1.51, 95% CI: 1.09-2.08) genetic models (all q0.2). The rs6013317 locus was associated with an increased risk of GDM in the allele (A vs G, OR=1.74, 95% CI: 1.15-2.63) genetic model (all q0.2). The GAGG haplotype and GGAG haplotype in haplotype block 1 (rs4811262, rs6096646, rs6096655, rs6013317), and the GGGA haplotype in haplotype block 2 (rs6068018, rs6123105, rs6013324, rs2869621) of the PTPN1 gene were all positively associated with an increased risk of GDM (all P0.05). Conclusion:PTPN1 gene polymorphisms may associated with risk of GDM, moreover, complex haplotype structures within the gene influence the risk of GDM.

Objective:To evaluate the effect of Bu-Zhong-Yi-Qi-Tang (BZYQT) combined with low molecular weight heparin (LMWH) on lower limb deep vein thrombosis (DVT) after fracture fixation in aged rabbits.Methods:Thirty-two elderly New Zealand rabbits of either sex, aged 36 months, weighing 3.5-4.0 kg, were divided into 4 groups ( n=8 each) using the random number table method: control group (C group), fracture fixation group (F group), low molecular weight heparin group (L group) and BZYQT combined with LMWH group (BL group). A model of fixation surgery for right femoral shaft fracture was established in anesthetized rabbits in F, L and BL groups. Starting from postoperative day 1, BL group received BZYQT at 3.6 ml/kg via gavage, F and L groups received normal saline at 3.6 ml/kg via gavage, L and BL groups received subcutaneous injection of LMWH at 200 IU/kg, and all the administrations were performed daily at 08: 00 for 7 consecutive days. On postoperative day 7, ultrasound examination was performed to assess lower limb DVT. Blood samples were collected from the marginal ear vein for determination of the serum concentrations of cortisol (COR), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and endothelin-1 (ET-1) by enzyme-linked immunosorbent assay. Femoral vein specimens were obtained under anesthesia for microscopic examination of the pathological changes of the femoral vein lumen and endothelial tissues (by HE staining) and of the morphology of vascular endothelial cells (by the transmission electron microscopy). Results:Compared with C group, the concentrations of serum COR, TNF-α, IL-6 and ET-1 were significantly increased in F, L and BL groups, and the incidence of lower limb DVT within 7 days after surgery was significantly increased in F and L groups ( P<0.05). Compared with F group, the incidence of lower limb DVT within 7 days after surgery was significantly decreased in L and BL groups, and the concentrations of serum COR, TNF-α, IL-6 and ET-1 were significantly decreased ( P<0.05), and the pathological damage was significantly reduced in BL group. Compared with L group, the incidence of lower limb DVT and concentration of IL-6 were significantly decreased ( P<0.05), and pathological damage was significantly alleviated in BL group. Conclusions:BZYQT combined with LMWH can prevent the occurrence of lower limb DVT after fracture fixation in aged rabbits.

Postoperative cognitive dysfunction(POCD)is the common postoperative complications in elderly patients,significantly affects their postoperative recovery and quality of life.With the intensification of population aging,how to effectively prevent and treat POCD has become an important topic in clinical re-search.Esketamine(ISLAT)serves as a new anesthetic drug and its potential in improving postoperative cog-nitive function has gradually attracted people's attention.Previous studies have shown that that esketamine can not only alleviate postoperative pain,but may also protect the neurons and reduce the incidence of POCD in elderly patients by regulating the balance of neurotransmitters and reducing inflammatory responses,and has potential clinical application value.However,the researches on the specific mechanisms of action and relat-ed signaling pathways of esketamine is still limited and requires further exploration.This article aims to inves-tigate the role of esketamine in reducing POCD in elderly patients and its related signaling pathway,clarifies the clinical usage strategy and precautions to provide a theoretical basis for clinical application.

Objective Through a non-inferiority trial design,to verify whether the efficacy of transcuta-neous electrical acupoint stimulation(TEAS)in intervening with nausea and vomiting after painless gastros-copy and colonoscopy was not inferior to that of ondansetron,and evaluate its effect on patient recovery.Meth-ods A total of 112 patients who experienced nausea and vomiting after painless gastroscopy and colonoscopy in the gastroscopy and colonoscopy center of the hospital from March 2022 to March 2023 were selected as the research subjects,and divided into the TEAS group(n=56)and the control group(n=56)according to the random number table method.The TEAS group received TEAS intervention,while the control group received ondansetron hydrochloride injection intervention.The non-inferiority margin was set at 10.0％.The interven-tion effective rate of nausea and vomiting after examination,as well as heart rate,blood pressure,length of stay,satisfaction,and visual analogue score(VAS)were compared between the two groups.Results The in-tervention effective rate of the TEAS group was close to that of the control group[82.4％(46/56)vs.80.4％(45/56)],risk difference(RD)=2.0％(95％CI:-9.8％to 13.8％),the lower limit of 95％CI(-9.8％)was higher than the preset cut-off value(-10.0％),and non-inferiority was established(P=0.032).Com-pared with before the examination,the heart rates of the two groups were slower,and the levels of systolic blood pressure(SEP)and diastolic blood pressure(DBP)were lower during the examination,and the differ-ences were statistically significant(P＜0.05).There was no statistically significant difference in the two groups of heart rate,SBP,DBP,length of stay[(69.9±14.2)min vs.(75.3±22.8)min],satisfaction score(9.8±0.6 vs.9.2±2.0),VAS(1.5±0.5 vs.2.1±0.5,P＞0.05).Conclusion The efficacy of TEAS in in-tervening with nausea and vomiting after painless gastroscopy and colonoscopy is not inferior to that of ondan-setron.

Objective:To explore the effects of a structured exercise intervention on the healthy physical fitness in patients with leukemia receiving umbilical cord blood transplantation.Methods:It was a randomized controlled trial, conducted from August 2022 to October 2023 at the Department of Hematology of the First Affiliated Hospital of the University of Science and Technology of China (Anhui Provincial Hospital). Fifty leukemia patients undergoing umbilical cord blood transplantation were recruited and were randomly assigned to either the control group (24 cases) or the intervention group (26 cases) using a random number table method. The control group received routine nursing care, health education, and exercise guidance during hospitalization. The intervention group were given moderate-intensity structured exercise intervention, including aerobic, resistance exercises, and flexibility training, three times per week for 30 to 40 minutes per session, over a period of 6 to 8 weeks. During the study, 2 patients withdrew due to disease reasons, and finally, 22 patients in the control group and 26 patients in the intervention group were obtained. The paired t-test, Wilcoxon test, and covariance analysis were used to compare the indices of healthy physical fitness before and after the intervention between the two groups, aiming to explore the effects of a structured exercise intervention on the healthy physical fitness of leukemia patients undergoing umbilical cord blood transplantation. Results:Before the intervention, there was no significant differences in baseline characteristics, such as age, gender and disease status between the two groups (all P>0.05). During the hospitalization phase, the rate of exercise participation in the intervention group was 73.4%, the frequency of exercise was (2.20±0.41) sessions per week and the duration of each exercise session was (34.34±5.05) minutes, and the Borg′s rating of perceived exertion was (13.04±0.82) points. After intervention, the indicators including cardiovascular endurance, muscle fitness, and functional activity status in the two groups were all decreased, and the reduction degree of the indicators were all significantly lower in the intervention group when compared with those in the control group [6-minute walk distance (48.81±30.39) m vs (143.05±77.26) m, grip strength of left hand (2.57±1.30) kg vs (6.72±4.88) kg, grip strength of right hand (2.47±1.97) kg vs (6.34±5.70) kg, muscle strength of left upper limb (4.12±2.07) times vs (8.18±5.26) times, muscle strength of right upper limb (3.96±2.29) times vs (7.91±5.16) times, 30 second chair standing test (3.65±1.98) times vs (7.86±4.34) times, and timed-up-and-go test (0.65±0.53) s vs (2.35±1.79) s] (all P<0.05). The flexibility fitness was improved in the intervention group after the intervention [sit-and-reach 2.00(-4.75, 8.18) cm vs 0(-9.75, 6.43) cm] ( P=0.011), but no significant differences was found in the control group ( P>0.05). Conclusions:The structured exercise intervention has advantages in reducing the decline of healthy physical fitness in patients with leukemia receiving umbilical cord blood transplantation, and exerts a protective effect on healthy physical fitness.

[Objective]To explore the connotation of the theory of"normal Qi and blood flow forward,stagnation and rebellion will lose their consciousness"and its clinical treatment of epilepsy.[Methods]Through consulting Huangdi Neijing and later medical classics,this paper analyzed the theoretical basis of"normal Qi and blood flow forward,stagnation and rebellion will lose their consciousness",and explained the epilepsy mechanism and treatment rules and prescriptions according to this principle.[Results]The occurrence of epilepsy is related to the incompatibility of Qi and blood between the five organs and a stoppage of the circulation of tri-Jiao,while epilepsy's long course is due to the reversal of Qi and blood of each organ itself,that leads the production of stagnation.Prescriptions are based on Chaihu Jia Longgu Muli Decoction,which is added or subtracted herbs according to symptoms,while also comforting the patient that epilepsy can be treated.The attached medical record was identified as Qi blockage,pyrophlegm affecting the mind,the treatment was to clear heat from liver,eliminate phlegm for resuscitation.Modified Chaihu Jia Longgu Muli Decoction plus Ditan Decoction was used and good results were achieved.[Conclusion]This theory reveals the consciousness,Qi,blood,Yin and Yang of the human body cannot be reversed,and the truth that it flows sequentially between the organs,and that each organ runs like a headless ring.The principle of treatment is"unobstruct",which aims to smooth the"Shidao",restore the normal function of the five internal organs,treat both manifestation and root cause of disease,finally make the consciousness clear.Using modified Chaihu Jia Longgu Muli Decoction,and with words of relief,the epilepsy will be relieved.

This experiment aims to investigate the effects of a dietary supplement of herbal tea resi-due on white feather broilers in the prospectives of growth performance,serum indexes and intesti-nal immune indexes.A total of 280 1-day-old white feather broilers with similar body mass and good health were randomly divided into 4 groups with 5 replicates per group and 14 birds per repli-cate.Group Ⅰ(control group)was fed a basal diet.Groups Ⅱ,Ⅲ and Ⅳ were fed a diet supple-mented with 2％,4％and 6％herbal tea residue powder,respectively.The feeding lasted for 49 days,and was divided into 2 phases from 1 to 21 days of age and 22 to 49 days of age.Blood,tissue and mucosa of the duodenum and jejunum were collected on 21 d and 49 d.Total cholesterol(T-CHO),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)and the activities of aspartate aminotransferase(AST)and alanine amin-otransferase(ALT)in the serum were examined.The villus height and crypt depth of the jejunum were observed and measured by morphology.The mRNA expression levels of intestinal interleukin-1β(IL-1β),interleukin-2(IL-2),interleukin-4(IL-4),interleukin-10(IL-10)and tumor necrosis factor-α(TNF-α)were determined by qPCR.The results showed that compared with group Ⅰ,the mass of group Ⅲ on 21 d and 49 d significantly increased(P＜0.05).The average daily feed intake of 22-49 d and 1-49 d significantly increased(P＜0.05).The average daily mass gain of 1-21 d,22-49 d and 1-49 d significantly increased(P＜0.05).In the serum of 21 d,compared with group Ⅰ,T-CHO in group Ⅱ significantly decreased(P＜0.05).TG in groups Ⅱ,m and Ⅳ significantly de-creased(P＜0.05).LDL-C and AST activity in group Ⅳ significantly decreased(P＜0.05).In the serum of 49 d,T-CHO in group Ⅲ,LDL-C in group Ⅳ,HDL-C of groups Ⅲ and Ⅳ significantly increased(P＜0.05),and the ALT activity of these two groups decreased(P＜0.05).AST activity in group Ⅱ significantly decreased(P＜0.05).In the duodenum of 21 d,compared with group Ⅰ,the expressions of TNF-α in group Ⅱ was significantly decreased(P＜0.05).In the duodenum of 49 d,the expression of IL-10 in group Ⅱ was significantly increased(P＜0.05),and the expression of IL-2 in groups Ⅲ and Ⅳ was significantly decreased(P＜0.05).In the jejunum of 49 d,the ex-pression of IL-10 in group Ⅱ was increased(P＜0.05),and the expression of IL-2 in groups Ⅲand Ⅳ was significantly decreased(P＜0.05).In conclusion,dietary herbal tea residue can regulate circulating lipid level and enhance intestinal immunity of white feather broilers without affecting their normal growth performance.This experiment also suggested that the a 2％-4％supplementa-tion of herbal tea residues to white feather broilers was of good effect.

The study adopted muscle injection of pVAX1-SP-GHRH(1-44)expression plasmid and electrostimulation to determine its effects on mouse growth and sow production performance.One hundred and fifty four-week-old C57 BL/6 female mice were randomly divided into 6 groups of 5 replicates each.Muscle single-injection followed by electrostimulation was performed.The con-trol group received an empty plasmid injection(80 μg/kg),while the treatment groups received pVAX1-SP-GHRH(1-44)plasmid injections(20,40,80,120,160 μg/kg).Twenty healthy preg-nant sows were randomly divided into 2 groups,each with 10 sows.Electrostimulation treatment was applied to the semimembranosus muscle of the pregnant sows after a single injection.The con-trol group received physiological saline injection,while the plasmid group received a 2 mg pVAX1-SP-GHRH(1-44)expression plasmid injection.Mouse weight,feed intake,and serum GHRH and IGF-1 levels were measured at days 0,7,14,21,and 28 after injection.Pregnant sows were bled via the tail vein at days 0,14,28,and 42 after injection,and their serum was separated to measure serum GHRH and IGF-1 levels.The birth weight,placental weight,number of piglets born,number of healthy piglets,number of weak piglets,number of deformed piglets,number of stillborn piglets,and number of mummified piglets were recorded at day 14.The mouse study re-sults showed that muscle injection of pVAX1-SP-GHRH(1-44)plasmid followed by electrostim-ulation could promote mouse feeding and increase weight gain(P＜0.05),significantly increase mouse serum GHRH and IGF-1 levels(P＜0.05),and maintain its effects until day 21.The results of the pregnant sow study showed that the average birth weight of the piglets in the plasmid group was significantly increased(P＜0.01),and the placenta weight was significantly increased(P＜0.05).The serum GHRH and IGF-1 concentrations in the plasmid group sows were significantly increased(P＜0.01).The study results showed that muscle injection of pVAX1-SP-GHRH(1-44)expression plasmid followed by electrostimulation could promote mouse feeding and increase weight gain,and also significantly improve the average birth weight and placental weight of the piglets in pregnant sows.
