ObjectiveTo investigate the willingness of rehabilitation patients within an urban medical group to accept downward referrals and analyze the influencing factors. MethodsFrom June to October, 2023, a survey was conducted using a simple random sampling method among neurological and orthopedic rehabilitation patients in hospitals within a specific urban medical group. The 2013 version of the Andersen Model was employed to construct a theoretical framework for the willingness of rehabilitation patients to accept downward referrals and influencing factors. Within this framework, a questionnaire was designed using a 5-point Likert scale, comprising three sections including personal characteristics, environmental features and healthcare service utilization choices, totaling 23 questions. A preliminary survey was conducted, and the questionnaire had underwent reliability and validity testing. ResultsA total of 350 questionnaires were collected, with 314 valid questionnaires. The willingness of rehabilitation patients to accept downward referrals was found to be associated with age, rehabilitation specialties, rehabilitation phases, previous experiences with downward referrals, awareness of and perceptions regarding bidirectional referral policies, and understanding and opinions about the urban medical group (χ² > 7.755, P < 0.05). The primary influencing factors were rehabilitation specialties, rehabilitation phases, previous experiences with downward referrals and perceptions of the necessity of bidirectional referral policies (P < 0.05). ConclusionRehabilitation specialties, rehabilitation phases, previous experiences with downward referrals and perceptions of the necessity of bidirectional referral policies are the primary factors that influenced the willingness of rehabilitation patients to accept downward referrals. We should formulate targeted and focused improvement measures based on the specific circumstances and key influencing factors of rehabilitation patients within the urban medical group regarding their willingness to accept downward referrals. Continuously enhancing the proportion of patients willingness to accept downward referrals is essential for the effective implementation of bidirectional referral for rehabilitation patients.

Objective:To investigate the efficacy and safety of low dose S-ketamine in analgesia of elderly patients with non-traumatic acute abdomen (NTAA) in emergency department.Methods:This was a randomized controlled trail. From January to August 2021, elderly patients with NTAA in the Emergency Department of the No. 904 Hospital of the Joint Logistic Support Force were selected. Analgesia was administered intravenously with 0.3 mg/kg S-ketamine or 0.1 mg/kg morphine injection for 15 min. Visual analogue score (VAS), respiratory rate, heart rate, non-invasive blood pressure and pulse oxygen saturation were recorded at 15 min, 30 min, 60 min and 90 min. The mini-mental state examination (MMSE) scores were recorded at 90 min after injection. The incidence of salvage analgesia, incidence of adverse reactions and diagnostic accuracy after analgesia were recorded in the two groups. VAS scores and vital signs were compared between the two groups by two-way repeated measures analysis of variance, and multiple comparisons between and within groups were performed.Results:A total of 137 elderly patients with NTAA were selected and randomly divided into two groups: S-ketamine group (SK group, 68 cases) and morphine group (M group, 69 cases). After the exclusion of patients with abscission, 39 cases were included in the SK group and 45 cases in the M group. VAS score of the SK group was significantly lower than that of the M group in 15 min after administration [(3.1±1.8) vs. (4.8±2.2)], and the difference was statistically significant ( P=0.013). There were no significant differences in vital signs and MMSE score between the two groups or within the group at each time point after medication (all P>0.05). However, the incidence of dizziness in the SK group was significantly higher than that in the M group (61.54% vs. 31.11%, P=0.005). Conclusions:Intravenous administration of low dose S-ketamine is not considered to be more effective than morphine in alleviating acute abdominal pain in elderly patients with NTAA. S-ketamine provides not only satisfactory analgesia but also short recovery time and high controllability. S-ketamine is one of the recommended analgesic alternatives of NTAA for elderly patients in emergency.

Objective:To compare the clinical effects of hip arthroplasty through direct anterior approach (DAA) in lateral decubitus in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia.Methods:The prospective study method was used to select the patients who needed hip arthroplasty in the Fourth Department of Orthopedics, the Second Affiliated Hospital of Harbin Medical University from January 2015 to December 2019. All of them were operated with lateral decubitus DAA. According to the inclusion criteria, they were divided into Kacshin-Beck disease hip osteoarthritis group (group A) and congenital acetabular dysplasia hip osteoarthritis group (group B). Hip Harris score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, visual analogue scale (VAS) score were conducted, and hip abduction angle and flexion angle were measured before surgery, 3, 14 days and 1, 3, and 12 months after surgery.Results:Nineteen and twenty-two patients were included in group A and group B, respectively. All patients successfully completed the surgery. There was no significant difference in Harris score between the two groups before surgery, 3, 14 days, and 1, 12 months after surgery ( P > 0.05). There were no significant differences in WOMAC score, VAS score, hip abduction angle and hip flexion angle between the two groups before surgery and each time point after surgery ( P > 0.05). In the same group, there were significant differences in Harris score, WOMAC score, VAS score, hip abduction angle and hip flexion angle at different time points ( P < 0.001). All postoperative indicators were significantly improved compared with those before surgery. Conclusions:There is no significant difference in the clinical effects of hip arthroplasty through lateral decubitus DAA in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia. This surgical method has good therapeutic effect on both types of hip osteoarthritis.

Objective:To investigate the changes of monocytic myeloid-derived suppressor cells (M-MDSC) in children with acute Kawasaki disease (KD) and its roles in the immunological pathogenesis of KD.Methods:A total of 38 children with acute KD were enrolled in the present study and 32 age-matched healthy children were selected as control group. The proportions of HLA-DR -CD11b + CD33 + CD15 -CD14 + M-MDSC and CD4 + CD25 + CD127 - regulatory T cells (Treg) in peripheral blood, concentrations of reactive oxygen species (ROS) and expression of arginase-1 (Arg-1), CD39, CD73, CD40, CD40L and CCR5 at protein levels were detected by flow cytometry. Quantitative real-time PCR was used to evaluate the transcription levels of inducible nitric oxide synthase (iNOS) in M-MDSC and the transcription levels of cytotoxic T-lymphocyte associated antigen 4 (CTLA4) and lymphocyte-activation gene 3 (LAG3) in Treg. Concentrations of NO, CCL3, CCL4, CCL5, IL-10 and TGF-β in the supernatants of cell culture were measured by ELISA. Results:(1) The proportion of HLA-DR -CD11b + CD33 + CD15 -CD14 + M-MDSC, the concentration of intracellular ROS and the expression of iNOS, CD39 and CD73 in M-MDSC decreased significantly in patients with acute KD as compared with those in the control group ( P<0.05), and the concentrations of NO, IL-10 and TGF-β in culture supernatant of M-MDSC were lower than those in the control group upon lipopolysaccharide (LPS) stimulation for 48 h ( P<0.05). All of the aforementioned indexes restored to some extent after intravenous immunoglobulin (IVIG) therapy ( P<0.05). No statistical differences were found in Arg-1 expression between healthy controls and patients with KD before or after IVIG therapy ( P<0.05). (2) CD40 expression on M-MDSC was significantly lower in the acute KD group than in the control group ( P<0.05). The concentrations of CCL3, CCL4 and CCL5 in the culture supernatants of M-MDSC were lower in the acute KD group than in the control group after LPS stimulation ( P<0.05). With IVIG treatment, all of the indexes were up-regulated significantly ( P<0.05), although CD40 expression was still lower in the acute KD group than in the control group ( P<0.05). (3) The proportion of CD4 + CD25 + CD127 -Treg and the expression of CTLA4, LAG3, CD40L and CCR5 reduced significantly in patients with acute KD as compared those in healthy controls ( P<0.05), and all increased remarkably after IVIG therapy ( P<0.05). Pearson correlation analysis showed a positive correlation between the proportions of M-MDSC and Treg in patients with acute KD ( r=0.58, P<0.05). Conclusions:Insufficiency and impaired function of M-MDSC might be a major cause of immune dysfunction in patients with acute KD.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Objective: To investigate the clinical features and genetic characteristics of cases with X-linked immunodeficiency with magnesium defect, Epstein-Barr virus (EBV) infection, and neoplasia (XMEN). Methods: Characteristics of clinical material, immunological data and gene mutation of two cases with XMEN in the same family in China were retrospectively analyzed. The related reports literature were searched by using search terms'MAGT1 gene’or'XMEN’. Results: The proband, a 2-year-eight-month old boy, was admitted due to 'Urine with deepened color for two days and yellow stained skin for one day’. He had suffered from recurrent upper respiratory tract infection and sinusitis previously. Hemoglobin level was 38 g/L. The absolute count of reticulocytes was 223.2×10⁹/L. Urobilinogen level was 38 μmol/L (3-16 μmol/L). Coomb's test was positive. Both total (77.2 μmol/L) and indirect bilirubin (66 μmol/L) levels were elevated. There was an inverted CD4⁺/CD8⁺T cell ratio (0.89). The gene sequencing results showed MAGT1 gene c.472delG, p.D158Mfs*6 mutation. His 1-year-6-month old brother, was also identified to have MAGT1 gene c.472delG, p.D158Mfs*6 mutation.The younger brother mainly suffered from recurrent upper respiratory tract infection, accompanied by an inverted CD4⁺/CD8⁺T cell ratio (0.45), an elevated ratio and number of total B cells (45.7%). A total of 7 reports were retrieved including 11 male cases caused by MAGT1 gene mutation. These 11 cases were characterized by EBV viremia (11 cases), recurrent upper respiratory tract infection, otitis media or sinusitis (10 cases), secondary neoplasia diseases (8 cases), reduction of CD4⁺/CD8⁺ T cell ratio (7 cases),and autoimmune thrombocytopenia or hemolytic anemia (2 cases). Conclusion XMEN often manifests as male onset, recurrent upper respiratory tract infection, otitis media or sinusitis, EBV viremia, lymphoproliferative disease or lymphoma, autoimmune diseases and reduction of CD4⁺/CD8 ⁺T cell ratio. NKG2D expression in NK cells is significantly reduced, and gene sequencing analysis shows a pathogenic mutation in MAGT1 gene.

This study was performed to evaluate the oncological and reproductive outcomes of childbearing-age women treated with fertility-sparing surgery (FSS) for non-epithelial ovarian tumors in China. One hundred and forty eight non-epithelial ovarian tumor women treated with FSS between January 1, 2000 and August 31, 2015 from two medical centers in China were identified. Progression-free survival (PFS) was 88.5%, whereas overall survival (OS) was 93.9%. Univariate analysis suggested that delivery after treatment is related to PFS (P = 0.023), whereas histology significantly influenced OS. Cox regression analysis suggested that only histology was associated with PFS and OS (P < 0.05). Among the 129 women who completed adjuvant chemotherapy (ACT), none developed amenorrhea. Among the 44 women who desired pregnancy, 35 (79.5%) successfully had 51 gestations including 35 live births without birth defects. Non-epithelial ovarian tumors can achieve fulfilling prognosis after FSS and chemotherapy. Histology might be the only independent prognostic factor for PFS and OS. FSS followed by ACT appeared to have little or no effect on fertility. Meanwhile, postoperative pregnancy did not increase the PFS or OS. Use of gonadotropin-releasing hormone agonist was not beneficial for fertility.

AIM:To investigate the curative effect of surgical resection combined with 100% concentration of autologous serum eye drops in the treatment of pterygium.

METHODS: Totally 120 cases of 120 eyes with pterygium from March 2015 to March 2016 in Zhongxiang People's Hospital were randomly divided into the control group and the experimental group. All patients were treated with tobramycin and dexamethasone ophthalmic ointment bandaged eyes postoperatively, and the next day tobramycin and dexamethasone eye drop were used, 2 drops, 6 times per day. The control group was treated with polyvinyl alcohol eye drops, 2 drops, 6 times per day, but the test group were treated with autologous blood concentration of 100% concentration of autologous serum eye drops, 2 drops, 6 times per day. The two groups were treated for 3wk. The curative effect was evaluated after operation of 3mo.

RESULTS: The preoperative general condition, ocular symptoms and signs score and Schirmer test of the two groups was no significant different(P>0.05). But there were significant differences of the two groups on ocular symptoms and signs score, corneal epithelium and/or matrix defect area and repair time, Schirmer test after the operation(P<0.05). In control group, the recurrence rate was 6.7%. And the experimental group were 3.3%. There was significant difference between the two groups(P<0.05).

CONCLUSION:The application of 100% concentration of autologous serum eyedrops after pterygium resection combined with autologous limbal stem cell transplantation of conjunctival flap was better for wound healing and ocular surface reconstruction postoperatively, and it achieved good curative effect.

Objective To compare the outcomes of off-pump versus on-pump CABG.Methods From 2002 to 2008,CABG was performed in 105 patients aged 80 years and over,including 45 without cardiopulmonary bypass (CPB) or off-pump (OP) CABG (OPCAB) and 60 with CPB (onpump CABG).The outcomes were compared between two groups.Results The mean ICU stay was (37.1±30.3) h in OPCAB group and (60.6±58.2) h in on-pump CABG group (P＜0.01).Average ventilator-assisted time was (10.8±9.7) h for OPCAB group versus (22.3±35.7) h for onpump CABG group (P＜0.01).Postoperative atrial fibrillation occurred in 31.1％ of OPCABG patients and 41.7 ％ of on-pump CABG patients (P＜0.01).The mortality rate was 5.0％ in OPCABG group versus 8.3％ in on-pump CABG group (P＜0.05).Conclusions OPCABG is a safe and efficient method of myocardial revascularization in the elderly patients with lower morbidity and complications.
