The construction of featured specialties is the current development strategy of community health service institutions to improve the service scope and to meet the health needs of residents. The rehabilitation medicine has undergone 12 years of development and become a relatively mature featured specialty in Fenglin Community Health Service Center. Based on the Fenglin′s experience, this article discusses the development status and restriction bottlenecks of general practice, and the development status and trend of rehabilitation medicine in the community; and also explores the integrated development model of community-featured specialty with general practice.

Dexmedetomidine (DEX) is a specific α2 receptor agonist, which has high analgesic and neuroprotective effects on the basis of less side effects.Due to the advantages of DEX,it is currently used in ICU,anesthesia and other fields.In recent years,its neuroprotective effect has attracted extensive attention.It has been reported that DEX plays a critical role in the injured development brain, postoperative cognitive dysfunction (POCD) and other diseases.The specific mechanism is unknown, which needs to be further explored.

Community health institutions have entered a new development stage of featured specialty construction. After 12 years of development, rehabilitation medicine now is the featured specialty of Fenglin Community Health Service Center. This article presents the train of thought and key points of specialty construction in primary care institutions based on the Fenglin′s experience. The positioning of featured specialty should be based on the community. The construction process should include 7 elements, namely, the standard operation procedure(SOP)of service system construction, the detailed publicity and implementation of the collaboration of specialists, prevention and control knowledge promotion for general practitioners, prevention and control knowledge education for community residents, service list, clinical efficacy evaluation, and clinical database. In the later iterations, the head of the department should always focus on the service system construction SOP and clinical database construction, and the rest parts can be assigned to the relevant team members.

Objective To explore the effect of environmental enrichment intervention on spatial memory function,expressions of phosphorylated cAMP response element binding protein (pCREB) and apoptotic regulated genes (Bcl-2 and Bax) in the hippocampus of immature rats with hypoxic-ischemic brain damage (HIBD).Methods Two kinds of raising environments were chosen:standard environment and environmental enrichment.Thirty-two Wistar rats aged 7 days were randomly divided into sham-operated group (n=10),environmental enrichment group (n=11) and standard environment group (n=11).Rats in both environmental enrichment group and standard environment group were induced animal models of HIBD using the way of Rice-Vannucci.Rats in the sham-operated group and standard environment group were raised in standard environment,while rats in the environmental enrichment group were raised in environmental enrichment.After 21 days of environmental enrichment intervention,the escape latency for searching the hidden platform of immature rats was detected by Morris water maze navigation test.The pCREB protein expression was detected by Western blotting;Bcl-2 and Bax expressions in the hippocampus were detected by immunohistochemisty.Results (1) On the fourth and fifth days of Morris water-maze test,the escape latency in the environmental enrichment group was shorter significantly as compared with that in the standard environment group (P＜0.05).(2) As compared with the lesion lateral hippocampus of standard environment group,the expressions ofpCREB (0.435±0.121 vs.0.756±0.101) and Bcl-2 (0.103±0.028 vs.0.165±0.017) in the lesion lateral hippocampus of environmental enrichment group were significantly higher (P＜0.05);however,the expression of Bax in the environmental enrichment group was statistically lower (0.402± 0.028 vs.0.325±0.019,P＜0.05).Conclusion Environmental enrichment intervention can improve the spatial memory ability in the hippocampus after HIBD,which indicates that the effectiveness of environmental enrichment intervention might be through the pathway of CREB-pCREB-apoptotic regulated genes (Bcl-2 and Bax).

Chronic kidney disease (CKD) is a serious health problem worldwide, whereas there is still no efficient cure. The gut microbiota plays a crucial role in maintaining human health and disease resistance, and multiple studies have confirmed that the gut microbiota is closely related to the occurrence and development of CKD. Starting from the "gut-kidney axis" theory, this article provides a systematic review of the changes in gut microbiota composition and function in patients with CKD, such as a decrease in the abundance of butyrate-producing bacteria Roseburia and Faecalibacterium prausnitzii. Besides that, the article explores the mechanisms by which the gut microbiota affects CKD progression, such as inflammation and immunity, and also describes the application methods of using the gut microbiota as a therapeutic target for CKD, such as fecal microbiota transplantation, microecologics, and dietary therapy, in order to provide microbial- based targets for the clinical diagnosis and treatment of CKD.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

The continuing discoveries of novel classes of RNA modifications in various organisms have raised the need for improving sensitive, convenient, and reliable methods for quantifying RNA modifications. In particular, a subset of small RNAs, including microRNAs (miRNAs) and Piwi-interacting RNAs (piRNAs), are modified at their 3'-terminal nucleotides via 2'-O-methylation. However, quantifying the levels of these small RNAs is difficult because 2'-O-methylation at the RNA 3'-terminus inhibits the activity of polyadenylate polymerase and T4 RNA ligase. These two enzymes are indispensable for RNA labeling or ligation in conventional miRNA quantification assays. In this study, we profiled 3'-terminal 2'-O-methyl plant miRNAs in the livers of rice-fed mice by oxidative deep sequencing and detected increasing amounts of plant miRNAs with prolonged oxidation treatment. We further compared the efficiency of stem-loop and poly(A)-tailed RT-qPCR in quantifying plant miRNAs in animal tissues and identified stem-loop RT-qPCR as the only suitable approach. Likewise, stem-loop RT-qPCR was superior to poly(A)-tailed RT-qPCR in quantifying 3'-terminal 2'-O-methyl piRNAs in human seminal plasma. In summary, this study established a standard procedure for quantifying the levels of 3'-terminal 2'-O-methyl miRNAs in plants and piRNAs. Accurate measurement of the 3'-terminal 2'-O-methylation of small RNAs has profound implications for understanding their pathophysiologic roles in biological systems.
