ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

Objective:To explore the clinical effects of free bilateral turbocharged anterolateral thigh flaps in tandem in repairing extensive wounds in the foot and ankle.Methods:The study was a retrospective observational study. From April 2020 to June 2023, 12 patients with extensive wounds in the foot and ankle who met the inclusion criteria were admitted to the Department of Wound Repair Surgery of Suzhou Ruihua Orthopedic Hospital, including 8 males and 4 females, aged 21 to 65 years. The wound area after debridement ranged from 27 cm×14 cm to 37 cm×20 cm. The bilateral perforator flaps pedicled with either oblique or descending branches of the lateral circumflex femoral artery were designed and harvested based on the size and shape of the wounds. The individual flap incision area ranged from 16 cm×9 cm to 34 cm×12 cm. The non-homologous perforator of the flap on the one side was turbocharged by anastomosing it with the gross muscular branch or main vessel of the oblique or descending branch of the lateral circumflex femoral artery from the flap. Subsequently, the proximal end of the oblique or descending branch of the lateral circumflex femoral artery and its accompanying vein from the flap on the one side were connected end-to-end with either the anterior tibial artery and vein, posterior tibial artery and vein, or dorsal foot artery and vein in the recipient area, the distal end of the oblique or descending branch of the lateral circumflex femoral artery and its accompanying vein from the flap on the one side were anastomosed end-to-end with a source vessel originating from flap on the other side. The wounds in the flap donor areas were sutured directly. The number and source of perforators carried by the flaps and the duration of the flap repair surgery were recorded. The survival of the flap, the occurrence of vascular crisis, and the wound healing at both donor and recipient areas were observed after surgery. The flap condition, appearance and function of the affected limb were observed during follow-up. At the last follow-up, the sensory function of the flap was assessed using the British Medical Research Council's sensory rating standard, the foot and ankle function of the affected limb was evaluated according to the American Orthopedic Foot and Ankle Society scoring standard.Results:A total 24 flaps were successfully harvested, carrying 60 perforators, including 34 perforators from the oblique branch of the lateral circumflex femoral artery, 24 perforators from the descending branch of the lateral circumflex femoral artery, one perforator from the transverse branch of the lateral circumflex femoral artery, and one perforator from the direct branch of the femoral artery. The duration of the flap repair surgery ranged from 4.2 to 9.0 hours. The flaps of 12 patients exhibited complete survival after surgery. A total of two flaps of two patients experienced venous crisis after surgery but survived through emergency exploration. One patient encountered undesirable wound healing at the donor area of flap on the one side after surgery, which healed after dressing change, debridement, and suturing. The remaining patients' donor area wounds healed. Two patients displayed impaired wound healing in the recipient area, which improved after dressing change and resection of residual sequestrum, and the wounds in the recipient area of other patients healed successfully. During the follow-up of 4-26 months, the flaps demonstrated favorable color and texture, slight edematous appearance, and partial sensory recovery, as well as good aesthetic and functional restoration of the affected limbs. At the last follow-up, the sensory function of the flap was assessed as grade S2 in 9 cases and grade S3 in 3 cases; the foot and ankle function of the affected limb was evaluated as excellent in two cases, good in 9 cases, and fair in one case.Conclusions:The bilateral turbocharged anterolateral thigh flaps have numerous sources of perforators. By implementing supercharging of non-homologous perforators within the flap, the vascular supply to the flap is turbocharged, thereby mitigating the risk of extensive flap necrosis. The flap is an effective approach for repairing extensive wounds in the foot and ankle, resulting in improved function of the affected limb after repair.

Objective:To disclose the epidemiological characteristics of the first human case of H9N2 subtype avian influenza and genetic characteristics of hemagglutinin (HA) gene of H9N2 avian influenza virus in Jiangsu province.Methods:Reverse transcription polymerase chain reaction (RT-PCR) assay was used to detect the nucleic acid of influenza virus A/B and various subtypes from throat swab specimens of patients with acute and severe respiratory infections of unknown cause. Sanger method was used to sequence the vial HA gene of H9N2 positive specimens. N-J phylogenetic tree of HA gene was constructed by using MEGA X software.Results:The first laboratory confirmed case of human infection with H9N2 avian influenza virus in Jiangsu province in March 2019 was reported by Suzhou Center for Disease Control and Prevention. Sequence analysis of the HA gene showed that the A/Suzhou/S683/2019 (H9N2) strain belonged to Y280-like sub-lineage of the Eurasian lineage, which had 99.23% nucleic acid identity with A/chicken/Shanghai/S1171/2018 (H9N2) strain. The amino acid sequence of the HA protein cleavage site is PSRSSR↓GLF, and the key amino acid in receptor binding site shared Q226L mutation. The location of potential glycosylation sites of HA protein of A/Suzhou/S683/2019 (H9N2) have changed.Conclusions:The H9N2 avian influenza virus obtained from the first case in Jiangsu province has low pathogenicity, but it may have acquired part of the ability to adapt to human hosts.

Objective: To explore the correlation between pull-up ability and upper body composition of male college students in a college in Guangxi, and to provide scientific guidance for college students’ exercise. Methods: A total of 685 male college students were randomly selected from a college in Guangxi.Pull up tests were implemented according to the national physical health test standards. Measurements of muscle mass, fat mass, fat percentage, etc. of the upper limbs were conducted by using the Ogilvy Body Composition Meter (TANITA MC-180). Data entry and analysis were performed by using SPSS 23.0. Results: The pass rate of male college students in the region was 21.7%; There was a statistically significant difference in the fat mass and percentage of body fat between males with different pull-up ability (F=11.30，14.18，12.91，15.22，P<0.01).After controlling age, height, weight and BMI, partial correlation analysis showed that there was a negative correlation between the pull-up ability of male college students and the fat mass and limb fat rate of both upper limbs(r=-0.22, -0.33, -0.31, -0.38, P<0.01). Conclusion The ability of male students in Guangxi to pull up is needed to be improved. Pull-up exercises can reduce fat mass and fat percentage in the upper limbs and improve body composition.

BACKGROUND: Studying the relationship between flexibility and body composition of college students is of great significance for enhancing the levels of physical health and sports. OBJECTIVE: To investigate the relationship between sit-and-reach and body composition of college students in Guangxi Zhuang Autonomous Region and differences between sexes. METHODS: Totally 2 175 students from a Guangxi university were randomly selected. Body composition was determined by the MC-180 body composition tester. The students were divided into four groups: ≤ 12.10 cm group,＞ 12.10-16.40 cm group,＞ 16.40-20.70 group and＞ 20.70 group according to quartile of sit-and-reach measured in accordance with the National Physical Health Test Standard. All data were processed by SPSS 22.0 software. RESULTS AND CONCLUSION: Sit-and-reach was significantly correlated with body mass index, percentage of body fat, fat-free mass index, upper limb lean mass and lower limb lean mass (P ＜ 0.05), and percentage of body fat was negatively correlated with sit-and-reach (P ＜ 0.05). The body mass index, fat-free mass index, upper limb lean mass and lower limb lean mass in the ≤ 12.10 cm group were significantly lower than those in the other groups. Fat-free mass index and upper limb lean mass were correlated with sit-and-reach in male college students (P ＜ 0.05). The fat-free mass index and upper limb lean mass in the＞ 16.40-20.70 cm group were significantly higher than those in the ≤ 12.10 cm group. Therefore, there is a positive correlation between the flexibility and fat-free mass index and upper limb lean mass in college students.

Objective: To investigate the epidemical features, etiological and clinical characteristics of HFMD in Suzhou city, from 2011 to 2015, providing the scientific supports for HFMD prevention and control. Methods: In each district of Suzhou city, at least five specimens of mild cases were collected per month, while all of the severe cases were sampled. The RNA from each sample was examined using a commercially available real-time PCR kit. Statistical analysis was performed using SPSS version 11.5 software. Results: We retrospectively analyzed HFMD epidemiological data in Suzhou from 2011 to 2015, a total of 4 552 outpatients in Suzhou city were diagnosed with HFMD, including 2 818 positive specimen, the total positive rate was 61.90%, and there was a significant difference in the positive rates between the adjacent years (χ²=186.09, P<0.0001). From 2011 to 2015 in Suzhou, HFMD mainly affected children aged 1 to 5 years old, 66.17% of them were 1to 3 years old. Enterovirus 71(EV71) and coxsackievirus A16(CVA16) were the predominant viral genotypes in Suzhou from 2011 to 2012, and 2014. In 2013, other EVs were dominant, the severe cases mainly correlated with EV71 subtypes, and the proportion of patients with severe disease was significantly decreased in 2013. Conclusions EV71 and CVA16 are still the important pathogens of HFMD, other EVs also occupy a certain proportion, it is the time to select one or two advantage pathogens from the other EVs into the HFMD monitoring.

BACKGROUND:Lymph-targeted tracing and therapy based on carbon nanotubes have been one of the hottest researches on targeting tumor diagnosis and treatment. To evaluate the accumulation of carbon nanotubes in axil ary lymph node can provide experimental evidences for developing nano-tracers and drug carriers which are more lymph-specific and more biocompatible. OBJECTIVE:To study the accumulation of the intravenously injected carboxylated single-wal ed carbon nanotubes in axil ary lymph nodes of Sprague-Dawley rats, and to evaluate their effect on blood cel s. METHODS:Sixty-four Sprague-Dawley rats were randomly divided into two groups. Rats in testing group were injected with carboxylated single-wal ed carbon nanotubes suspension (2 mg/kg), while those in control group were injected with 5%glucose solution (1 mL/kg), both through the tail vein, three times per week. Four periods of 7, 60, 90 and 120 days were set (the 120-day period referred to 90 days of administration fol owed by 30 days of drug withdrawal). At the end of each period, eight rats from each group were randomly picked out, to col ect blood samples via the abdominal aorta for blood routine test. Final y the axil ary lymph nodes were observed, and the lymph node samples of rats in the testing group were col ected and analyzed at 120 days by transmission electron microscope. RESULTS AND CONCLUSION:Compared with the control group, black staining of axil ary lymph nodes of rats in testing group was not obvious at the end of the 7-day period. However, with the increase of the dosing periods, the lymph nodes of the rats in the testing group became enlarged, firm and black stained, coupled with a significant rising in the percentage of blood neutrophils. After 30 days of drug withdrawal, the size of the rat axil ary lymph nodes was reduced and black staining partly faded, with the decreasing of blood neutrophil percentage. Under the transmission electron microscope, abundant carboxylated single-wal ed carbon nanotubes were uptaken by lymphocytes to form a large number of phagocytic vacuoles after drug withdrawal for 30 days. It indicates that the short-term tracing of rat axil ary lymph nodes by carboxylated single-wal ed carbon nanotubes injected through the tail vein is relatively weak, while the long-term intravenous injection can cause their accumulation in rat axil ary lymph nodes, coupled with the increase of neutrophils;after drug withdrawal, the carboxylated single-wal ed carbon nanotubes can be slowly cleared by the lymph nodes.
