Objective To explore the expression profile of Wnt4 in rat kidney during renal development and its effect on renal development. Methods Rats with embryonic age of 18 days (E 18 d) , 20 days (E 20 d) as well as postnatal age of 0 day (P 0 d), 1 day (P 1 d), 3 days (P 3 d), 5 days (P 5 d) and 7 days (P 7 d) were selected. Expression levels of Wnt4 in rat kidney during renal development were quantified by immunohistochemistry and Western blot in all time points. Results Immuno?histochemistry analysis showed that during E 18 d to P 7 d, Wnt4 mainly expressed in proximal tubules, ureteric bud, comma shaped bodies and S shaped bodies of nephrogenic zone;the expression in the distal tubule was weak;the expression in renal corpuscle decreased with time;Western blot analysis showed that the expression of Wnt4 in rat kidney began to decrease from E 18 d and reached bottom at P 1 d then rise again until P 7 d when it dropped again. Conclusion During renal development, Wnt4 proteins were involved in the development of the nephrogenic zone through regulating canonical Wnt/β-catenin signaling pathway, and was involved in extension of proximal tubules by inducing the non canonical Wnt/PCP signaling pathway. Expression of Wnt4 protein in rat kidney was closely related to nephron formation and development of proximal tubules.

Objective To compare the initial stability between anterior transpedicular screw (ATPS) fixation,anterior plate (AP) fixation and combining anterior and posterior (CAP) fixation for subaxial cervical three-column injury.Methods Six specimens of cervical spine were prepared.After measurement of the range of motion (ROM) of the intact cervical spine,the specimens were made into models of three-column injury.After the models were simulatively reconstructed using an anterior cervical cage,they were stabilized by ATPS,AP and CAP.After the ROMs of the models in the 3 fixation states were measured,the data were normalized by standardizing them to the intact state ROM which was set at 100％.The normalized ROMs of the models in the 3 fixation states were compared.Results The normalized ROMs of AP fixation state in flexion,extension,lefi lateral bending,right lateral bending,left axial rotation and right axial rotation were 119.68±8.34％,119.63±6.74％,115.20±7.91％,117.47±7.81％,120.67±5.99％ and 112.35 ± 8.42％,respectively,significantly larger than those of the intact state (P ＜ 0.05).The normalized ROMs of the other 2 states in all directions were significantly smaller than those of the intact state (P ＜0.05).The normalized ROM of ATPS state in flexion was 87.48 ± 5.31％,significantly larger than that of CAP state (69.60 ± 2.06％) (P ＜ 0.05).There were no significant differences between the normalized ROMs of ATPS state and those of CAP state in extension (65.53 ± 4.36％ versus 67.17 ± 3.10％),in left lateral bending (82.13 ± 2.85％ versus 82.30 ±4.69％),in right lateral bending (81.78 ± 3.42％ versus 81.27 ± 2.79％),in left axial rotation (83.20 ± 2.30％ versus 82.95 ± 2.40％),or in right axial rotation (83.03 ± 1.30％ versus 83.60 ± 6.56％) (P ＞ 0.05).Conclusions In subaxial cervical three-column injury,the initial stability of ATPS fixation may be superior to that of AP fixation and similar to that of CAP fixation.We believe that ATPS can provide enough initial stability for subaxial cervical three-column injury.

Objective To investigate the effect of irbesartan combined with resuvastatin on early diabetic nephropathy( DN) complicated with cardiovascular disease,and its influence on SDF -1/CXCR4 expression. Methods From January 2016 to December 2017,130 early DN patients complicated with cardiovascular disease in the Second People＇s Hospital of Linhai were selected as study objects,and according to the digital table,they were randomly divided into three groups: irbesartan group(control group 1,n＝43),resuvastatin group(control group 2,n＝43) and irbesartan combined with resuvastatin group (observation group,n＝44).The clinical efficacy,blood pres-sure,blood lipids and SDF -1/CXCR4 expression were compared among the three groups.Results After treatment,the total effective rate in the observation group was 93.18%(41/44 ),which in the control group 1 was 69.77%(30/43),which in the control group 2 was 74.42%(32/43),there was statistically significant difference among the three groups(χ2＝12.341,10.106,all P＜0.05).After treatment,the levels of SBP and DBP in the observation group had statistically significant differences compared with those in the control group 1 and control group 2( F＝23.087,20.249,all P＜0.05).After treatment,there were statistically significant differences in TC,TG,HDL-C and LDL-C between the observation group and control group 1,control group 2(F＝18.408,15.623,14.852,9.845,all P＜0.05).After treatment,the level of SDF -1 in the observation group was significantly higher than that before treatment,and which was also significantly higher than that in the control group 1 and control group 2(F＝21.085,P＜0.05).After treatment,the positive rate of CXCR4 in the observation group was significantly higher than that before treatment,and compared with that in the control group 1 and control group 2,the difference was statistically significant(F＝23.641,P＜0.05).Conclusion Irbesartan combined with resuvastatin in the treatment of early DN patients with cardiovascular disease has significant clinical efficacy,can effectively improve blood pressure and blood lipid levels,significantly improve the level of SDF -1 and CXCR4 positive rate.

Objective To explore the effect of water extracts from Semen Astragali Complanati (Flatstem Milkvetch Seed,hereinafter“SAC”)on lipid metabolism in hyperlipidemia model rats with kidney-yang deficiency pattern,so as to try to discover the mechanism.Methods Female 10-week-old SD rats were randomly divided into six groups (each n =10):normal group,model group,estrogen group,SAC low-dose group,SAC mid-dose group and SAC high-dose group.The rat model was induced by bilateral ovariectomization combined with high-fat diet feeding.And rats of normal group and model group were in-tragastrically (i.g.)administered with saline,those of estrogen group were i.g.with estradiol valerate (0.2 mg/kg),and three SAC groups were i.g.with SAC extract at the dose of 34,68 and 136 mg/kg for consecutive 8 weeks.The body weight of rats were recorded,serum TC,TG,HDL-C and LDL-C were measured and serum E2 ,FSH and estrogen receptors (ERα,ERβ)mRNA in liver tissue were de-tected.Results Compared with the normal group,the body weight of rats of model group increased sig-nificantly after three weeks’high-fat feeding (P <0.001 );from Week 5 the level of total cholesterol (TC)and low density lipoprotein cholesterol(LDL-C)increased significantly (P <0.001 or P <0.01), and from Week 7 triglyceride(TG)and high density lipoprotein cholesterol(HDL-C)also did (P <0.001 or P <0.05);serum E2 significantly decreased (P <0.01),and follicle stimulating hormone(FSH)in-creased (P <0.05),the expression of ER-αmRNA in liver significantly decreased(P <0.05).High dose of SAC significantly reduced the serum level of TG and TC from Week 7 (P <0.05 or P <0.001), middle dose of SAC reduced the level of LDL-C and increased HDL-C significantly at the same time point (P <0.05,P <0.01),and a more week later,the low dose increased the serum level of HDL-C (P <0.05).Despite the levels of E2 and FSH of model rats showed no significant difference after treatment by SAC (P >0.05),the expression of ER-αmRNA in liver tissue increased in all SAC groups (P <0. 05).Conclusion The effect of regulating blood lipid metabolism of SAC had been proved.The poten-tial mechanism could be via upregulating the expression of estrogen receptors to amplify the signals trans-mitted by the receptors,which may make up the low estrogen level to direct at the disorder of lipid metab-olism during peri-menopausal period.

Objective:To evaluate the effect of adductor canal block(ACB)and local infiltration anesthesia(LIA)around the knee joint on inflammatory responses in the patients undergoing total knee arthroplasty(TKA).Methods:Sixty American Society of Anesthesiologists physical status Ⅱor Ⅲ patients of both sexes, aged 54-76 yr, scheduled for elective TKA, were divided into 2 groups ( n=30 each) using a random number table method: ACB group (group A) and ACB combined with LIA around knee joint group (group AL). ACB was performed with 0.5% ropivacaine 15 ml after endotracheal intubation in group A and group AL, and in addition LIA was performed around the knee joint after the osteotomy was completed during surgery in group AL.The patient-controlled ACB analgesia was applied at the end of surgery in both groups.The analgesic solution contained ropivacaine 400 ml (in 0.9% normal saline 200 ml), and the analgesic pump was set up to deliver a 5 ml bolus dose with a 30-min lockout interval and background infusion at 5 ml/h.When visual analog scale score>4, and pain was still not relived at 30 min after pressing by patients, pethidine hydrochloride 100 mg was intramuscularly injected as rescue analgesic.Peripheral venous blood samples were collected immediately before surgery (T 0) and at 24, 48 and 72 h after surgery (T 1-3) for determination of serum interleukin-6 (IL-6) and IL-10 concentrations by enzyme-linked immunosorbent assay.The muscle strength on the affected side was assessed at T 1-3.The patients′ satisfaction score, requirement for rescue analgesia, and adverse effects were recorded. Results:Compare with group A, the serum IL-6 concentrations were significantly decreased and serum IL-10 concentrations were increased at each time point after surgery, postoperative patients′ satisfaction scores were increased, the requirement for rescue analgesia was decreased ( P<0.05), and no significant change was found in the quadriceps strength of the affected limb and incidence of adverse reactions after surgery in group AL ( P>0.05). Conclusion:ACB and LIA around the knee joint can mitigate postoperative inflammatory responses in the patients undergoing TKA.

Background Results of genetic testing for antipsychotic drugs can guide the rational use of drugs in clinical practice and help improve the clinical symptoms of patients with schizophrenia.However,there is currently limited evidence in China regarding the impact of genetic testing results on medication adherence,social function and drug side effects of antipsychotic drug treatment.Objective To explore the improvement of clinical symptoms,medication adherence and social function in patients with schizophrenia under the guidance of antipsychotic drug gene testing results and examine the safety of drug treatment,so as to provide references for ifor precise treatment of schizophrenia patients.Methods Patients with acute schizophrenia who received hospitalization at Dazhou Minkang Hospital from July 2019 to August 2021 as well as met the diagnostic criteria of the International Classification of Diseases,tenth edition(ICD-10)were selected as research subjects(n=144).Based on random number table,subjects were divided into study group and control group,with 72 cases in each group.Control group received drug treatment based on the doctor's clinical experience,while study group received drug treatment based on the results of gene testing for antipsychotic drug.Both treatments lasted for 12 weeks.At baseline as well as 2,4,8 and 12 weeks after treatment,Positive and Negative Syndrome Scale(PANSS),8-item Morisky Medication Adherence Scale(MMAS-8),Social Functional Rating Scale(SFRS)and Treatment Emergent Symptom Scale(TESS)were adopted for assessment.Result Time effect and group effect of the reducing rate of PANSS,MMAS-8 and SFRS scores in the groups were statistically significant(Ftime=95.251,6.650,14.101,Fgroup=38.055,58.175,128.221,P<0.01).The interaction effect of the reduction rates of MMAS-8 scores in two groups was statistically significant(Finteraction=5.837,P<0.01).The group effect and interaction effect of the severity scores of drug side effects and patient pain scores in two groups were statistically significant(Fgroup=7.553,81.533,Finteraction=8.693,9.322,P<0.01).Conclusion In terms of improving clinical symptom relief,medication adherence,social function and drug side effects,medication for patients with schizophrenia guided by genetic testing of antipsychotic drugs may be more effective than that relying on medication based on clinical experience.

Objective:To explore the non-target metabonomics of serum in worker's pneumoconiosis (CWP) patients with latent tuberculosis and the biomarkers of latent tuberculosis infection of pneumoconiosis.Methods:In December 2018, 39 CWP inpatients from a hospital in Beijing were taken as subjects. The subjects were screened for latent tuberculosis using the in vitro release test of mycobacterium tuberculosis-interferon (IGRAs) test. According to the screening results, 21 positive patients with latent tuberculosis infection were selected as the latent tuberculosis group of pneumoconiosis. While 18 negative patients with CWP alone were selected as the pneumoconiosis group. Polarity components of metabolites were analyzed by UPLC-QTOF/MS. The data was processed with Progenesis QI software for multidimensional statistical analysis. Identification of structure of differential metabolites were matched through accurate mass and secondary mass spectrum. Searching the Human Metabolome Database (HMDB) , differential metabolites were imported into MetaboAnalyst 4.0 to analyze the metabolic pathways.Results:All 42 differential metabolites were screened out. Excepted for exogenous metabolites, 14 endogenous differential metabolites were identified. Compared with the pneumoconiosis group, 6 metabolites including PC [18∶4 (6Z, 9Z, 12Z, 15Z) /P-18∶1 (11Z) ], 3-Oxododecanoyl-CoA in the latent tuberculosis group were up-regulated, while 8 metabolites including the Stearoyl-CoA, (2S) -Pristanoyl-CoA were down-regulated. These results might be related to lipid, fatty acid and arachidonic acid metabolism pathways.Conclusion:There are significant differences in serum metabonomics between the patients with latent tuberculosis of pneumoconiosis and the patients with ordinary pneumoconiosis, which provide a reference for the study of biomarkers for the diagnosis of latent tuberculosis infection of pneumoconiosis.
