OBJECTIVE: To observe the clinical efficacy of deep needling at Xiaguan (ST7) combined with electroacupuncture and warm acupuncture for adenoid hypertrophy (AH) in children. METHODS: Seventy-two children with AH were randomly divided into an observation group (36 cases, 5 cases dropped out, 1 case was eliminated) and a control group (36 cases, 4 cases dropped out, 2 cases were eliminated). The observation group received deep needling at Xiaguan (ST7) combined with electroacupuncture and warm acupuncture. The needle depth of Xiaguan (ST7) was 20-30 mm. Electroacupuncture was applied at Xiaguan (ST7), Yingxiang (LI20), Yintang (GV24⁺), Baihui (GV20), with continuous wave, in frequency of 2 Hz. Warm acupuncture was applied at Zusanli (ST36). The treatment was performed 30 min each time, once a week for 12 weeks. The control group was treated with mometasone furoate aqueous nasal spray, one spray per nostril each time, once a day for 12 weeks. The symptom score, adenoid-to-nasopharynx ratio (A/N), and 18-item health-related quality-of-life survey for children with obstructive sleep apnea (OSA-18) score were observed before and after treatment in the two groups, and the clinical efficacy was evaluated after treatment. RESULTS: After treatment, the total scores of symptom, A/N, and OSA-18 scores were decreased compared with those before treatment in both groups (P<0.01), the above indexes in the observation group were lower than those in the control group (P<0.01, P<0.05). The total effective rate in the observation group was 93.3% (28/30), which was higher than 83.3% (25/30) in the control group (P<0.05). CONCLUSION Deep needling at Xiaguan (ST7) combined with electroacupuncture and warm acupuncture could effectively improve symptoms, reduce adenoid volume, and improve the quality of life in children with AH.

OBJECTIVE: To investigate the short-and med-term clinical efficacy of unicompartmental knee arthroplasty(UKA)for the treatment of medial knee osteoarthritis (OA) in elderly patients with anterior cruciate ligament deficiency(ACLD). METHODS: A retrospective analysis was conducted on 31 patients aged over 75 years old with primary medial knee OA and ACLD who underwent UKA between January 2018 and December 2022. The cohort included 12 males and 19 females, aged from 75 to 91 years with an average age of (79.56±4.54) years, with 13 left knee, 16 right knee, and 2 bilateral knees. Clinical outcomes were assessed preoperatively and at final follow-up using the visual analogue scale (VAS), Hospital for Special Surgery(HSS) score, range of motion (ROM), hip-knee-ankle angle (HKA), and tibial component posterior slope angle (TCPSA). Complications such as infection, prosthesis wear, prosthesis loosening, and dislocation were also recorded. RESULTS: All 31 patients were followed up from 12 to 63 months with an average of (28.34±10.56) months. The average postoperative TCPSA was (4.83±1.31)° ranged from 2.5° to 6.8°. At the final follow-up, there was significant improvement in VAS (3.24±0.53) vs. (6.59±0.69), HSS score (85.19±4.45) vs. (64.38±5.94), ROM (118.83±5.38)° vs. (98.85±4.08)°, and HKA (176.83±5.16)° vs. (169.57±6.28)° compared to preoperative values (P<0.05). No cases of infection, prosthesis loosening, or dislocation were reported. CONCLUSION UKA provides favorable short-and mid-term outcomes for elderly patients with medial knee OA and ACLD . However, long-term clinical efficacy needs further investigation through extended follow-up.

As the brain's resident immune cells, microglia perform crucial functions such as phagocytosis, neuronal network maintenance, and injury restoration by adopting various phenotypes. Dynamic imaging of these phenotypes is essential for accessing brain diseases and therapeutic responses. Although numerous probes are available for imaging pro-inflammatory microglia, no PET tracers have been developed specifically to visualize anti-inflammatory microglia. In this study, we present an ¹⁸F-labeled PET tracer (QTFT) that targets the P2Y₁₂, a receptor highly expressed on anti-inflammatory microglia. [¹⁸F]QTFT exhibited high binding affinity to the P2Y₁₂ (14.43 nmol/L) and superior blood-brain barrier permeability compared to other candidates. Micro-PET imaging in IL-4-induced neuroinflammation models showed higher [¹⁸F]QTFT uptake in lesions compared to the contralateral normal brain tissues. Importantly, this specific uptake could be blocked by QTFT or a P2Y₁₂ antagonist. Furthermore, [¹⁸F]QTFT visualized brain lesions in mouse models of epilepsy, glioma, and aging by targeting the aberrantly expressed P2Y₁₂ in anti-inflammatory microglia. In a pilot clinical study, [¹⁸F]QTFT successfully located epileptic foci, showing enhanced radioactive signals in a patient with epilepsy. Collectively, these studies suggest that [¹⁸F]QTFT could serve as a valuable diagnostic tool for imaging various brain disorders by targeting P2Y₁₂ overexpressed in anti-inflammatory microglia.

Immunologic thrombocytopenic purpura(ITP)is an immune-mediated hemorrhagic disorder that can be categorized as purpura disease in traditional Chinese medicine(TCM).Modern TCM views ITP as a syndrome being deficiency in the origin and excess in the superficiality,and the treatment of ITP is usually from the pathogenesis of heat,deficiency,and stasis.Professor Deng Cong proposes that the onset of ITP results from the interaction of internal etiological factors and external etiological factors,the invasion of wind acting as the exogenous cause,while emotional disturbances and chronic fatigue serving as endogenous contributors.The primary pathogenic factors are wind,deficiency,and stasis.The onset of ITP is due to wind stirring latent pathogens,liver failing to store blood,spleen failing to govern blood,and kidney failing to generate blood,which cause the extravasation of blood from the vessels.ITP primarily involves the liver,spleen and kidney.Internal stirring of wind pathogen,liver failing to store blood,spleen failing to govern blood,and kidney failing to generate blood are the critical factors contributing to the refractory ITP.Syndrome differentiation and treatment of ITP requires the identification of the functional characteristics of the liver,spleen,and kidneys as well as their interrelationships.Therapeutic strategies should focus on dispelling wind and soothing the liver,resolving stasis and strengthening the spleen,and tonifying the kidneys to supplement essence,with emphasis on using wind-dispelling medicinals,liver-soothing medicinals,and medicinal with affinity to flesh and blood.Professor Deng Cong's approach to treating ITP from the pathogenesis of wind,deficiency and stasis will provide an additional option for the treatment of ITP,particularly for the patients with chronic and refractory thrombocytopenic purpura.

Drug-induced liver injury(DILI)is a common adverse drug reaction in clinical practice,which can lead to acute liver failure and even death in severe cases.In recent years,with the continuous introduction of new drugs and the expansion of their usage,the incidence and mortality rates of DILI have shown an upward trend,posing significant challenges to public health and clinical treatment.Macrophages,as a crucial component of the innate immune system,exhibit high plasticity and heterogeneity.They can polarize into pro-inflammatory M1 type or anti-inflammatory M2 type in response to microenvironmental signals.Research has demonstrated that macrophage polarization plays a central regulatory role in the occurrence and progression of DILI by influencing various processes such as inflammatory responses,cell apoptosis,and tissue repair.This review focuses on elucidating the regulatory mechanisms and roles of macrophage polarization in DILI,providing a theoretical framework for developing precise immunotherapeutic strategies.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:To investigate the arsenic metabolism pattern and possible influencing factors in the population in drinking-water-borne endemic arsenic poisoning (drinking-water-borne arsenic poisoning for short) areas.Methods:In December 2004, a cluster sampling method was used to select arsenic poisoning population (arsenic poisoning group) and healthy population (control group) in drinking-water-borne arsenic poisoning area of Bayannur City, Inner Mongolia Autonomous Region as the survey subjects. A questionnaire survey was conducted. Arsenic content in drinking water at home of survey subjects, the levels of urinary arsenic and its metabolites, including [trivalent arsenic (As Ⅲ), inorganic arsenic (iAs), monomethylarsenic acid (pentavalent, MMA V), dimethylarsenic acid (pentavalent, DMA V), total arsenic (tAs), percentage of inorganic arsenic (iAs%), percentage of monomethylarsenic acid (MMA%), percentage of dimethylarsenic acid (DMA%), primary methylation index (PMI), secondary methylation index (SMI)] were tested using high performance liquid chromatography-inductively coupled plasma mass spectrometry; nail arsenic and nail selenium levels were tested using atomic fluorescence spectrometer. The influencing factors of arsenic metabolism pattern were analyzed by multiple linear regression. Results:A total of 536 survey subjects were included, including 155 individuals in the arsenic poisoning group and 381 in the control group. The water arsenic level ranged from 0.0 to 825.7 μg/L. Compared with the control group, there was no significant difference in the distribution of gender, education level and dental fluorosis in the arsenic poisoning group ( P > 0.05), but there were significant differences in the distribution of age, marital status, smoking, drinking and water arsenic ( P < 0.05). Compared with the control group, the levels of urinary As Ⅲ, iAs, MMA V, DMA V, tAs, MMA%, MMA/DMA and nail arsenic in the arsenic poisoning group were higher ( P < 0.05), while the levels of urinary DMA%, SMI and nail selenium were lower ( P < 0.05); but there was no statistically significant difference in the levels of urinary iAs% and PMI ( P > 0.05). Gender, education level, depth of wells, water arsenic, total number of wells and nail arsenic were the influencing factors of urinary As Ⅲ (β = - 19.82, - 23.83, 0.61, 0.21, 7.26, 2.98, P < 0.05). Age, depth of wells, water arsenic and nail arsenic were the influencing factors of urinary tAs (β = 3.18, 3.25, 1.31, 15.59, P < 0.05). Gender, education level, depth of wells, water arsenic, total number of wells and nail arsenic were the influencing factors of urinary iAs (β = - 20.47, - 25.90, 0.64, 0.25, 7.87, 3.11, P < 0.05). Age, gender, education level, water arsenic and nail arsenic were the influencing factors of urinary MMA V (β = 0.52, - 17.07, - 21.84, 0.22, 2.77, P < 0.05). Age, depth of wells, water arsenic and nail arsenic were the influencing factors of urinary DMA V (β = 2.35, 2.47, 0.85, 9.22, P < 0.05). Conclusions:Compared with healthy individuals, there are differences in arsenic metabolism pattern among individuals with drinking-water-borne arsenic poisoning. Age, gender, education level, depth of wells, water arsenic, total number of wells and nail arsenic may be influencing factors of different arsenic metabolism patterns.

Objective To investigate the environmental contamination related to first patient with carbapenem-re-sistant Acinetobacter baumannii(CRAB)infection and the infection status of relevant patients in a newly established intensive care unit(ICU)of a hospital in Tibetan area,and analyze the transmission risk.Methods From the ad-mission in ICU of a patients who was first detected CRAB on November 15,2021 to the 60th day of hospitalization,all patients who stayed in ICU for＞48 hours were performed active screening on CRAB.On the 30th day and 60th day of the admission to the ICU of the first CRAB-infected patient,environment specimens were taken respectively 2 hours after high-frequency diagnostic and therapeutic activities but before disinfection,and after disinfection but before medical activities.CRAB was cultured with chromogenic culture medium.Results Among the 13 patients who were actively screened,1 case was CRAB positive,he was transferred from the ICU of a tertiary hospital to the ICU of this hospital on November 19th.On the 40th day of admission to the ICU,he had fever,increased frequency for sputum suction,and CRAB was detected.The drug sensitivity spectrum was similar to that of the first case,and he also stayed in the adjacent bed of the first case.64 environmental specimens were taken,and 9 were positive for CRAB,with a positive rate of 14.06％,8 sampling points such as the washbasin,door handle and bed rail were positive for CRAB after high-frequency diagnostic and therapeutic activities.After routine disinfection,CRAB was detected from the sink of the washbasin.Conclusion For the prevention and control of CRAB in the basic-level ICU in ethnic areas,it is feasible to conduct risk assessment on admitted patients and adopt bundled prevention and con-trol measures for high-risk patients upon admission.Attention should be paid to the contaminated areas(such as washbasin,door handle,and bed rail)as well as the effectiveness of disinfection of sink of washbasin.

Objective To investigate the biological function and main molecular mechanism of long noncoding RNA RMRP(lncRNA RMRP)in endometrial carcinoma.Methods The specimens of carcinoma tissues and adjacent tissues of 30 patients with endometrial carcinoma who received surgical treatment in our hospital were collected.RT-qPCR was used to detect the expression of lncRNA RMRP in endometrial carcinoma tissues and adjacent tissues,and HESC cells and HEC-1-A cells.The endometrial carcinoma cell line HEC-1-A was cultured in vitro,and the Vector,pcDNA-RMRP,NC-siRNA,RMRP-siRNA,NC mimic,miR-580-3p mimic,pcDNA-RMRP+NC mimic,pcDNA-RMRP+ miR-580-3p mimic,RMRP-siRNA+Vector,RMRP-siRNA+pcDNA-JAK2,NC inhibitor,and miR-580-3p inhibitor were transfected into HEC-1-A cells as the Vector group,the pcDNA-RMRP group,the NC-siRNA group,the RMRP-siRNA group,the NC mimic group,the miR-580-3p mimic group,the pcDNA-RMRP+NC mimic group,the pcDNA-RMRP+miR-580-3p mimic group,the RMRP siRNA+Vector group,the RMRP-siRNA+pcDNA-JAK2 group,the NC inhibitor group,and the miR-580-3p inhibitor group respectively.RT-qPCR was used to detect the expression of lncRNA RMRP and miR-580-3p in cells.CCK-8 was used to detect cell proliferation rate.The apoptosis rate was detected by flow cytometry analysis.Bioinformatics software and dual luciferase reporter gene experiment were used to predict and verify the targeted relationships between miR-580-3p and lncRNA RMRP,as well as miR-580-3p and JAK2.Western blot was used to detect the protein expression of JAK/STAT signaling pathway.Results Compared with adjacent tissues,lncRNA RMRP was highly expressed in endometrial carcinoma tissues(P<0.05).Compared with HESC cells,the expression of lncRNA RMRP in HEC-1-A cells was significantly increased(P<0.05).pcDNA-RMRP significantly promoted cell proliferation and inhibited cell apoptosis,while RMRP-siRNA significantly inhibited cell proliferation and promoted cell apoptosis,with statistically significant diferences(P<0.05).miR-580-3p was the downstream target miRNA of lncRNA RMRP,and lncRNA RMRP could negatively regulate the expression of miR-580-3p.JAK2 was the downstream target gene of miR-580-3p,and miR-580-3p could negatively regulate the expression of JAK2 protein.pcDNA-RMRP significantly increased the protein levels of JAK2,p-JAK2 and p-STAT3 in the cells,while co-transfection of pcDNA-RMRP and miR-580-3p mimic significantly decreased the protein levels of JAK2,p-JAK2 and p-STAT3,with statistically significant diferences(P<0.05).RMRP-siRNA could signifi-cantly reduce the protein levels of JAK2,p-JAK2 and p-STAT3 in cells.After co-transfection of RMRP-siRNA and pcDNA-JAK2,the protein levels of JAK2,p-JAK2 and p-STAT3 were significantly increased,with statistically significant diferences(P<0.05).In addition,co-transfection of RMRP-siRNA and pcDNA-JAK2 increased cell proliferation and decreased cell apoptosis,with statistically significant diferences(P<0.05).Conclusion Knockdown of lncRNA RMRP could inhibit endometrial carcinoma cell proliferation and promote cell apoptosis by regulating JAK2/STAT3 signaling pathway,which might be a potential therapeutic target for endometrial carcinoma.

Objective:To construct a predictive model to assess the risk of severe respiratory syncytial virus infection among children under five years in China, conduct preliminary validation of this model by using external data, and develop an individual risk assessment tool available for their parents.Methods:The admission after RSV infection was used as a marker of severe infection. Based on the evidence of RSV hospitalization-related risk factors and real-world data, such as the prevalence of various risk factors in children under five years old in China, a Monte Carlo-based individual RSV hospitalization risk prediction model for children under five years old was constructed. Taking Suzhou City as an example, the model was externally validated, and an interactive risk prediction tool (RSV HeaRT) was developed on the WeChat mini-program platform.Results:The estimation model showed that in children under five years old in China if the population did not have any risk factors for severe RSV infection, the RSV annual hospitalization rate was 2.2/1 000 (95% CI: 0.9/1 000-7.5/1 000). Based on this baseline hospitalization rate and the prevalence of related risk factors in Suzhou, the model predicted an RSV hospitalization rate of 8.0/1 000 (95% CI: 4.6/1 000-24.4/1 000) for children under five years old annually in Suzhou, which was close to the reported RSV hospitalization rate in literature (10/1 000-20/1 000). In the developed RSV HeaRT WeChat mini-program, target users (such as parents of children) could input basic information, disease history, and social environmental factors of the child into the mini-program, and the tool could provide real-time feedback on the following predicted results: First, the relative risk of hospitalization due to RSV infection in current children compared to general children; Second, the probability of hospitalization due to RSV infection within the next year; Third, the relative risk of adverse outcomes during hospitalization in the event of RSV infection. Conclusion:This study is based on real-world evidence related to RSV hospitalization risk and constructs an RSV hospitalization risk prediction model suitable for Chinese children based on the combination of the current prevalence of risk factors in children under five years old in China. The accuracy of the prediction model results has been preliminarily demonstrated. Based on this design, the RSV HeaRT developed can facilitate parents to evaluate the hospitalization risk of children.
