Objective This study aims to investigate and analyze the distribution of MN blood type among ethnic minorities in China. Methods Through a systematic retrieval of the 981 literature related to MN blood group distribution, 120 literature, meeting the criteria of this study, with complete data were selected. The literature covers 49 ethnic minorities. SPSS 26 statistical software was used to analyze the data. Results The results showed that among the 49 ethnic minorities in China, the phenotype distribution of MN blood type was MN>MM>NN, with proportions of 42.54%, 41.86%, and 15.06% respectively. The gene frequency for MN blood type exhibited a trend of m>n, with a gene frequency of m being 0.6313 and n being 0.3687. Cluster analysis divided the Chinese ethnic minorities into three groups based on the gene frequency for m, showing the characteristics of Group I>Group II>Group III. Conclusion The MN blood type characteristics in Chinese ethnic minorities show a higher frequency of the M gene compared to the N gene. The frequency of the M gene is higher in southern ethnic minorities than in northern ones. There are significant differences between southwestern ethnic minorities and the Han nationality, but no differences with long-term mixed/settled Han populations.

Objective:The present study aims to investigate whether there is a shared alteration of the resting-state functional connectivity and amplitude of low frequency fluctuation (ALFF) within the limbic network across all three clinical phases of bipolar disorder.Methods:From July 2019 to December 2021, 107 patients diagnosed with bipolar disorder (bipolar disorder group) were recruited from the Institute of Mental Health at Xiangya Second Hospital, Central South University. Additionally, 46 healthy controls matched for age, gender, and education level were enrolled as the control group. According to the total scores of the Young Mania Rating Scale (YMRS) and the Hamilton Depression Rating Scale (HAMD 17), individuals with bipolar disorder can be categorized into three groups: bipolar manic group, bipolar depressive group, and bipolar euthymic group. Resting state functional magnetic resonance imaging data were collected from all the participants, and seed-based functional connectivity and ALFF in the limbic network were conducted to compare differences among three mood states and controls using One-way ANOVA and post hoc analysis. Finally, correlation analyses using Pearson or Spearman coefficients were performed between statistically significant intergroup differences in functional connectivity/ALFF values and total scores as well as factor scores on clinical rating scales. Results:In comparison to the healthy controls, there was a significant decrease in functional connectivity between the anterior cingulate gyrus and hippocampus across all three clinical phases of bipolar disorder after Bonferroni correction ( t=-2.60--2.07, P<0.05). Furthermore, the ALFF in the anterior cingulate gyrus during three phases showed a significantl reduction following false discovery rate correction ( t=-4.41--3.51, P<0.05). Moreover, a decreased functional connectivity between the left anterior cingulate gyrus and left hippocampus during the depressive phase demonstrated a significant negative correlation with work interest subscores of the HAMD 17 ( r=-0.406, P=0.021). Conclusions:Dysconnectivity and reduced activity within the anterior cingulate of the limbic network may represent common alterations of mood regulation disorder throughout all three clinical phases of bipolar disorder.

Objective:To evaluate the clinical effects of posterior reduction in the treatment of acute severe traumatic lumbar spondylolisthesis.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with acute severe traumatic lumbar spondylolisthesis who had been treated by posterior reduction at Department of Spinal Surgery, Zhengzhou Orthopaedic Hospital from June 2010 to December 2018. There were 7 males and 5 females with an age of (25.7±1.8) years. The spondylolisthesis was at L4 in 4 cases and at L5 in 8 cases, and grade Ⅲ in 7 cases, grade Ⅳ in 4 cases and grade Ⅴ in 1 case according to the Meyerding classification. By the American Spinal Injury Association (ASIA) grading, the preoperative neurological function was at level B in 6 cases, at level C in 4 cases, and at level D in 2 cases. All the 12 patients underwent posterior reduction and internal fixation with pedicle screws, as well as intervertebral bone graft fusion. Operation time and intraoperative blood loss were recorded. Clinical efficacy was evaluated by visual analogue scale (VAS) and Oswestry disability index (ODI) before and after surgery, and neurological function was evaluated by ASIA grading. X-ray, CT plain scan and reconstruction were used to observe internal fixation and bone grafting.Results:All patients were followed up for (18.5±2.1) months. The operation time was (165.7±42.3) min and the blood loss (497.7±75.3) mL. The VAS pain scores [(2.7±0.3) points and (1.8±0.2) points] and ODIs (18.2%±2.3% and 14.5%±2.6%) at 2 weeks after operation and at the last follow-up were significantly lower than the preoperational values [(8.5±0.6) points and 72.3%±12.3%] ( P<0.05), but there was no statistically significant difference between 2 weeks after operation and the last follow-up ( P>0.05). At the last follow-up, X-rays and CT scans showed good fixation and adequate bone grafting; the spondylolisthesis was grade 0 in 10 cases and grade I in 2 cases; the ASIA level of neurological function was C in 2 cases, D in 3 cases, and E in 7 cases. Healing of surgical incision was delayed in 2 patients but responded to symptomatic treatment. Follow-ups observed no such complications as loosening or pulling out of internal fixation. Conclusion:In the treatment of acute severe traumatic lumbar spondylolisthesis, posterior reduction can effectively restore the spondylolisthesis sequence and restore spinal stability, leading to satisfactory curative outcomes.

Premature ovarian failure （POF） is a common gynecological endocrine disease ，which can cause follicular development stagnation or premature failure in the ovary ，leading to ovarian function loss ，and seriously affecting women ’s physical and mental health . Traditional Chinese medicine shows less toxicity and side effects but significant effect in the treatment of POF . Chinese herb monomers are the active ingredients of traditional Chinese medicine that exert their effects ，and their chemical structure are determined . From the perspective of Chinese herb monomers ，the author reviewed the mechanism of their effect on improving POF . The results showed that icariin ，quercetin，resveratrol and ginsenoside Rg 1 could improve the ovarian function of POF model animals by activating the phosphatidylinositol 3-kinase/protein kinase B signaling pathway ，inhibiting oxidative stress and apoptosis of granulosa cells ，promoting ovarian autophagy ，and regulating the level of sex hormones ；puerarin and resveratrol can improve the ovarian function of POF model by interfering with Wnt/ β-catenin signaling pathway ，reducing oxidative stress response ，and inhibiting follicular atresia . Although the Chinese herb monomers have certain effect in improving POF，most of them remain in the experimental stage ，and the clinical efficacy in improving POF cannot be objectively evaluated . In the future ，the development of new dosage forms of Chinese herb monomers should be strengthened to lay a foundation for the development of new drugs for treating POF .

As known,simultaneous determination of various chemical indicators is one of the future trends in quality control of traditional Chinese medicines because of the extremely complex chemical compositions. This project is to screen the quality markers that can accurately control the quality of the Bufonis Venenum by exploring the intrinsic correlation of components. In this study,venom of Bufo bufo gargarizans from 17 different sources were used as research samples,and the contents of 7 bufogenin were determined by HPLC-DAD. Then,the data obtained were analyzed by Spearman correlation analysis and principal component analysis( PCA). In addition,a stepwise regression analysis was used to establish a predictive model for the contents of the seven bufogenin components( independent variable) and the total contents of the bufogenin( dependent variable). The results indicated that there is a significant positive correlation between the contents of telocinobufagin and cinobufotalin,and there is a significant positive correlation between the contents of bufalin,cinobufagin and resibufogenin. In contrast,the contents of telocinobufagin and cinobufotalin are negatively correlated with the contents of bufalin,cinobufagin and resibufogenin. However,the correlation between gamabufotalin and bufotalin and other components are not obvious. Furthermore,further study found that there is a correlation between the sum of the contents of bufalin,cinobufagin and telocinobufagin and the total contents of the bufogenin. In fact,the application of bufalin,cinobufagin and telocinobufagin as the quality control indicators of the Bufonis Venenum can better reflect the quality characteristics of the Bufonis Venenum compared with the previous quality control indicators. The conclusions will provide a reference for the revision of the quality standards of the Bufonis Venenum.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary. RESULTS: A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001). CONCLUSIONS The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.

Targeted temperature management (TTM) is referred to as the reducing of the core body temperature to a specific temperature to repair or mitigate tissue damage caused by inadequate blood perfusion. It is a promising treatment method. However, as it is widely used in clinical practice, more and more disputes have been made about the scope and effect of TTM. This paper will review the mechanism of TTM,the method of its implementation and its application in the disease, so as to provide references for further understanding of TTM and optimizing the clinical application of TTM.
