The contents about the central action mechanisms of needling Zusanli (ST 36) were sorted by summarizing the relevant literatures published in the past 10 years, and it was found that: by comparing acupuncture at Zusanli (ST 36), other acupoints or sham points, most studies showed that Zusanli (ST 36) had relatively specific characteristics in the brain function response; studies on the central action mechanisms of Zusanli (ST 36) were mainly focused on sequelae of cerebral apoplexy, pain, gastrointestinal diseases, weight loss and drug addiction withdrawal and so on; acupuncture manipulations, stimulation methods, individual differences, stimulation quantity, and stimulation duration, etc. could also induce different brain function responses; acupuncture at Zusanli (ST 36) had an after-working effect, also called long-term effect, but with poor repeatability. So, it was suggested that the future studies should focus on the factors that affect the clinical efficacies and experimental results, including the compatibility effects of the acupoints, reproducibility of research results, sample size, acupuncture methods, long-term effects and disease entities.

Objective: To compare and analyze functional brain response characteristics by applying acupuncture or moxibustion to Zusanli (ST 36) in patients with functional dyspepsia (FD) and investigate the differences of central action mechanism resulting from acupuncture or moxibustion. Methods: A total of eligible 24 FD cases were divided into two blood-oxygen-level dependent (BOLD) sequences for functional magnetic resonance imaging (fMRI) scan. The amplitude of low frequency fluctuation (ALFF) analyses were conducted on the data of location phase, structure phase, resting state before acupuncture/moxibustion, working state during acupuncture/moxibustion and resting state after acupuncture/moxibustion using Data Processing Assistant for Resting-State fMRI (DPARSF) software. Results: Acupuncture and moxibustion produced significant differences in functional brain response. The working state during acupuncture/moxibustion mainly decreased ALFF values in the right supramarginal gyrus, right superior parietal lobule, right frontal gyrus, upper right occipital lobe, right precuneus and right cingulate gyrus. At the same time, it increased ALFF values in the left cerebellum, right caudate nucleus, right cerebellum and left inferior gyrus. The differences during the resting state after acupuncture/moxibustion were significantly smaller than the working state in intensity and size. It mainly resulted in decrease in ALFF values in the right postcentral gyrus and right supramarginal gyrus and increase in ALFF values in the left precuneus, orbital part of inferior frontal gyrus and right cerebellar peduncles. Conclusion: Needling and moxibustion at Zusanli (ST 36) can produce significant differences in immediate functional brain response.

Aim To evaluate the effectiveness and safety of remimazolam tosylate for administering general anesthesia in morbidly obese patients.Methods This clinical trial was conducted at a single center from De-cember 2021 to October 2023.It assessed 108 morbid-ly obese patients(body mass index,BMI≥40)who underwent laparoscopic sleeve gastrectomy.Patients were randomly assigned to either the remimazaolam group(Group R)or the propofol group(Group P)for general anesthesia induction and maintenance.The primary outcome was to compare the incidence of ad-verse events and postoperative recovery characteristics between the two groups.Results During induction pe-riod,the incidence of adverse events was higher in group P,including hypotension(P＜0.01),hypox-emia(P＜0.05),bradycardia(P＜0.01),and in-creased vasopressor requirement(P＜0.05).The time to loss of consciousness and BIS falling to 60 was shor-ter in group P than in group R(P＜0.01).There were no statistically significant differences between the two groups in terms of postoperative quality of recovery(QoR-40 score),24-hour postoperative pain visual an-alogue scale(VAS)scores and morphine consump-tion.In conclusion,remimazolam tosylate,utilized for anesthesia induction in morbidly obese patients,signif-icantly reduced hypotension and hypoxemia compared to propofol,while it could also maintain similar postop-erative recovery quality.Conclusions Remimazolam is effective in reducing the incidence of hypotension and hypoxaemia during the induction period of general anaesthesia in morbidly obese patients and it is compa-rable to propofol in terms of quality of postoperative re-covery.

Objective Diminished ovarian reserve (DOR) severely affects the life of women and the estrogen replacement therapy for it has obvious adverse effects. This article aimed to study the effect of polygoni multiflori radix preparata (PMRP) on DOR in rats and provide a therapeutic option for clinical medication. Methods Sixty female SD rats were randomly divided into six groups of equal number,normal control,DOR model control,high-dose PMRP (4 g/kg),medium-dose PMRP (2 g/kg),low-dose PMRP (1 g/kg),and positive control. The DOR model was established by gavage of tripterygium glycosides as 75 mg/kg every morning,followed by administration of PMRP in the PMRP groups,Estradiol valerate at 0.18 mg/kg in the positive control group and distilled water in the model control group in the afternoon,all for 30 consecutive days. The estrous cycle of the rats was observed,the levels of serum estradiol (E2),follicle-stimulating hormone (FSH),luteinizing hor-mone (LH),anti-Müllerian hormone (AMH) and inhibin-B (INH- B) were determined by ELISA,the ovarian and uterine indexes were obtained,and the ovarian morphology was observed by HE stai-ning,and the counts of follicles at different stages were recorded. Results Compared with the normal controls,the DOR model rats showed modeling time-related lengthening,irregularity and even disorder of the estrous cycle,with a few epithelial cells or keratino-cytes and leucocytes on the vaginal smear at 11-30 days. The estrous cycle was normal in the PMRP and positive control groups at 1-10 days and relatively prolonged at 11-30 days. In comparison with the normal control group,the DOR model rats exhibited a signifi-cantly decreased levels of serum E2 ([302.6±42.9] vs [155.7±46.8] pg/mL,P<0.05) and INH-B ([494.5±84.1] vs [299.2± 106.8] pg/mL,P<0.05) but increased levels of FSH ([7.2±0.5] vs [21.7±1.2] mIU/mL,P<0.05) and LH ([17.4±1.2] vs [25.0±1.0] mU/mL,P<0.05). The INH-B level was markedly elevated in the PMRP and positive control groups as compared with that in the DOR models (P<0.05). The counts of follicles and corpora lutea were remarkably lower in the DOR model rats (P<0.05) while that of developing follicles markedly higher in the PMRP and positive control groups than in the normal control group (P<0.05). The numbers of atretic follicles+corpora lutea were significantly increased in the high-dose PMRP group but decreased in the low-dose PMRP group (P<0.05) and positive controls (P<0.05). The counts of primordial and developing follicles were dramatically higher in the PMRP and positive control groups than in the DOR model controls (P<0.01) and so were the numbers of atretic follicles+corpora lutea in the high-and medium-dose PMRP groups (P<0.05). Conclusion Polygoni multiflori radix preparata can effectively protect the reproductive function of female rats by inhibiting tripterygium glycosides-induced toxicity to the ovary.

OBJECTIVETo observe the effect of dopamine receptor (DR2) activation on hypoxia/reperfusion injury (HRI) in the neonatal rat cardiomyocytes, and to explore its mechanism.

METHODSThe hypoxia/reperfusion (H/R) injury model was established in primarily cultured neonatal rat cardiomyocytes, and randomly assigned: control, H/R, bromocriptine (Bro) and haloperidol (Hal) groups. The cell apoptosis was detected using inverted microscope, transmission electron microscope and flow cytometry (FCM). The lactate dehydrogenase(LDH) and superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in cell medium were analyzed. The expression of mRNA and protein of caspase-3, caspase-8, caspase-9, Fas, Fas-L, Cyt C and Bcl-2 were detected by RT-PCR and Western blot, respectively.

RESULTSCompared with the control group, apoptosis rate, LDH activity, MDA content and the expression of pro-apoptotic factors and anti-apoptotic factors were increased, but SOD activity was decreased in H/R group. Compared with the H/R group, all index above-mentioned were down-regulated or reversed in Bro-group, and had no obvious differences in Hal-group.

CONCLUSIONThe neonatal rat cardiomyocytes injury and apoptosis caused by hypoxia/reperfusion can be inhibited with DR2 activation, which mechanism is related to scavenging oxygen radical.

The liver injury induced by Polygonum multiflorum Thunb. (PM) was investigated based on idiosyncratic hepatotoxicity model co-treated with lipopolysaccharide (LPS) at a non-hepatotoxic dose. Sprague-Dawley (SD) rats were intragastrically administered with three doses (18.9, 37.8, 75.6 g crude drug per kg body weight) of 50% alcohol extracts of PM alone or co-treated with non-toxic dose of LPS (2.8 mg·kg(-1)) via tail vein injection. The plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were assayed and the isolated livers were evaluated for histopathological changes. The dose-toxicity relationships of single treatment of PM or co-treatment of LPS were investigated comparatively to elucidate the idiosyncratic hepatotoxicity of PM. The results showed that no significant alterations of plasma ALT and AST activities were observed in the groups of solo-administration of LPS (2.8 mg·kg(-1), i.v.) or different dosage (18.9, 37.8 and 75.6 g·kg(-1), i.g.) of PM, compared to normal control group (P > 0.05); while significant elevations were observed in the co-administration groups of PM and LPS. Treatment with LPS alone caused slight infiltration of inflammatory cells in portal area but no evident hepatocytes injury. Co-treatment with LPS and PM (75.6 g·kg(-1), i.g.) caused hepatocyte focal necrosis, loss of central vein intima and a large number of inflammatory cell infiltration in portal areas. When further reduce the dosage of PM, significant increases of plasma ALT and AST activities (P < 0.05) were still observed in co-administration groups of LPS and PM (1.08 or 2.16 g·kg(-1)), but not in LPS or PM solo-administration groups. Nevertheless, the co-treatment of low dosage of PM (0.54 g·kg(-1)) with LPS did not induce any alteration of plasma ALT and AST. In conclusion, intragastric administration with 75.6 g·kg(-1) of PM did not induce liver injury in normal rats model; while the 2 folds of clinical equivalent dose of PM (1.08 g·kg(-1)) could result in liver injury in the LPS-based idiosyncratic hepatotoxicity model, which could be used to evaluate the idiosyncratic hepatotoxicity of PM.

To investigate the difference of liver injury in rats gavaged with crude and processed Polygoni Multiflori Radix. The 75% ethanol extract of crude and processed Polygoni Multiflori Radix (50 g · kg(-1) crude medicine weight/body weight) were continuous oral administered to rats for 6 weeks. Serum biochemical indicators were dynamically detected, the change of liver histopathology was assessed 6 weeks later. Principal component analysis (PCA) was adopted to screen sensitive indicator of the liver damage induced by polygoni multiflori radix. Biochemical tests showed that the crude Polygoni Multiflori Radix group had significant increase of serum ALT, AST, ALP, DBIL and TBIL (P < 0.01 or P < 0.05) and significant decreases of serum IBIL and TBA (P < 0.01 or P < 0.05), while the processed Polygoni Multiflori Radix group showed no obvious changes, compared to the untreated normal group. Histopathologic analysis revealed that crude Polygoni Multiflori Radix group exhibited significant inflammatory cells infiltration in portal area around the blood vessels, tissue destruction and local necrosis of liver cells. There were not obvious pathological changes in processed Polygoni Multiflori Radix group. The results demonstrated that the injury effect of processed Polygoni Multiflori Radix on liver injury of rats was significantly lower than that of unprocessed, and that processing can effectively reduce the hepatotoxicity of Polygoni Multiflori Radix. Traditional transaminase liver function indicators were not sensitive for crude Polygoni Multiflori Radix induced liver damage. The serum content of DBIL and TBIL can reflect the liver damage induced by crude Polygoni Multiflori Radix early and can be sensitive indicators for clinical monitoring the usage of it.

OBJECTIVETo establish the Chinese Pediatric Evaluation of Disability Inventory (PEDI) norms in Chongqing, China.

METHODSPEDI (English version) was translated into Chinese and proof read by back-translation. A total of 1 140 children stratified by age were randomly selected from Chongqing and evaluated by the Chinese version of the PEDI. The obtained data were statistically analyzed.

RESULTSOf 1 140 questionnaires, 1 075 (94.3%) were valid. The data showed that the raw and scale scores of PEDI increased with age, but the standard scores did not increase with age. The raw, scale, and standard scores on self-care and social function scales were significantly lower than American PEDI norms in some age periods (P<0.05), but the raw, scale, and standard scores on mobility scale were not significantly different from American norms (P>0.05).

CONCLUSIONSThe PEDI norms in Chongqing have been successfully established, and can be used to assess the daily function in children, judge the degree of daily function impairment, evaluate the effect of rehabilitation training, and make the rehabilitation plan for disabled children.
