As an important setting for the administration of vaccinations, the reasonable setting up and standardized management of vaccination clinics will enhance immunization service quality, public satisfaction, and improve the vaccination rate to protect people′s health. In recent years, various provinces in China are continuously promoting the standardized construction and management of vaccination clinics. However, the level of standardization management remains unbalanced, and the capacity of vaccination services needs to be further improved. This paper reviews the standardized management process of vaccination clinics, summarizes the practice and achievements in various regions, and analyzes the challenges and issues during these processes, to provide reference for improving the standardized management level of vaccination clinics in the future.

Objective:To evaluate the therapeutic role of balanced matching concept in the surgical release of moderate and severe elbow stiffness after trauma.Methods:A retrospective study was conducted to analyze the clinical data of 20 patients who had been treated by surgical release from June 2022 to January 2024 for elbow stiffness after moderate and severe trauma at Department of Orthopedic Trauma, The First Hospital Affiliated to Air Force Medical University of PLA using the balanced matching concept (combination of elbow soft tissue balance and bone matching). There were 15 males and 5 females, with an age of (33.0±8.9) years. Six left sides and 14 right sides were affected. The elbow stiffness was severe in 13 cases and moderate in 7 cases. Six patients had mainly bony stiffness, 4 patients mainly soft stiffness, and 10 patients mixed stiffness. The elbow flexion and extension, Mayo elbow performance score (MEPS) and disabilities of the arm, shoulder, and hand (DASH) score were recorded and compared before release and at the last follow-up. The recurrence of ectopic ossification, infection, iatrogenic fracture and other complications of the elbow joint of the affected limb were recorded.Results:All the 20 patients were followed up for (16.6±3.5) months. At the last follow-up, the elbow flexion and extension (121.8°±8.9° and 14.8°±8.2°) were significantly greater than those before operation (73.5°±25.7° and 47.3°±19.2°), and the MEPS and DASH scores [ (90.0±5.6) points, (5.6±3.0) points] were significantly better than those before operation [(53.0±12.8) points, (62.1±14.0) points] ( P<0.05). Iatrogenic fracture of the ulna occurred in 1 patient, and pinky numbness occurred in 1 patient after surgery. None of the patients had recurrence of ectopic ossification or wound infection. Conclusion:In the surgical release of moderate and severe elbow stiffness after trauma, the concept of balanced matching plays a positive role by facilitating the functional restoration of the elbow and reducing the incidence of complications.

Objective:To compare the safety and efficacy of 3D-printed porous bioceramic artificial bone and artificial bone substitutes in the treatment of limb bone defects.Methods:A total of 220 patients with post-traumatic limb bone defects admitted to Xijing Hospital Affiliated to Air Force Medical University of the Chinese People's Liberation Army (34 cases), the Third Hospital of Hebei Medical University (60 cases), Xi'an Honghui Hospital (28 cases), the Third Hospital of Southern Medical University (18 cases), Changsha Third Hospital (28 cases), Foshan Traditional Chinese Medicine Hospital (16 cases), Foshan Fuxing Chancheng Hospital (12 cases), and Henan Provincial Orthopaedic Hospital (24 cases) from May 2022 to October 2023 were included as research subjects. According to the manufacturing method of the bone graft material, the subjects were randomly divided into the 3D printed porous bioceramic artificial bone group (3D printing group) and the artificial bone substitute group (non-3D printing group) at a ratio of 1:1 by the envelope method. Adverse events that might be related to the surgery were selected through correlation evaluation and classified as abnormal laboratory indicators, systemic or other site symptoms and abnormalities, and local symptoms and abnormalities of the affected limb. The safety of the two groups was compared. The bone graft fusion rate, bone defect repair and healing rate, and short form 12 (SF-12) score of the two groups were calculated to evaluate the postoperative recovery.Results:Thirty-two cases were excluded (4 cases refused to use their data after reconsideration, 7 cases were not used after preoperative assessment, and 21 cases exceeded the standard for body mass index and laboratory indicators upon re-examination). A total of 188 cases were randomly divided into the 3D printing group and the non-3D printing group according to the random method, with 94 cases in each group. Among them, 11 cases in the 3D printing group and 9 cases in the non-3D printing group dropped out due to loss to follow-up. Finally, 168 cases completed the follow-up, including 83 cases in the 3D printing group and 85 cases in the non-3D printing group. In the 3D printing group, there were 53 males and 30 females, with an average age of 47.9±12.7 years; in the non-3D printing group, there were 53 males and 32 females, with an average age of 48.6±12.9 years. A total of 51 cases in the two groups experienced adverse events related to the surgery, including 13 cases of abnormal laboratory indicators (5 cases in the 3D printing group and 8 cases in the non-3D printing group), 15 cases of systemic or other site symptoms and abnormalities (9 cases in the 3D printing group and 6 cases in the non-3D printing group), and 23 cases of local symptoms and abnormalities of the affected limb (13 cases in the 3D printing group and 10 cases in the non-3D printing group). There was no statistically significant difference in the incidence of adverse events between the two groups ( P>0.05). The bone graft fusion rates of the 3D printing group and the non-3D printing group at 6 months after surgery were 99%(82/83) and 99%(84/85), respectively, and the bone defect repair and healing rates were 89%(74/83) and 89%(76/85), respectively. At the time of 12 months after surgery, the bone graft fusion rates were 99%(82/83) and 99%(84/85), respectively, and the bone defect repair and healing rates were 94%(78/83) and 92%(78/85), respectively. There was no statistically significant difference in the bone graft fusion rate and bone defect repair and healing rate between the two groups ( P>0.05). The SF-12 scores during the screening period were 27.82±2.96 points and 27.22±4.23 points in the 3D printing group and the non-3D printing group, respectively, and at 3 months after surgery were 28.08±3.13 points and 27.64±3.16 points, at 6 months after surgery were 29.42±3.10 points and 28.55±3.45 points, and at 12 months after surgery were 29.78±2.80 points and 29.58±2.94 points, respectively. There was no statistically significant difference between the groups ( P>0.05). Both groups of surgeries were successfully completed without any serious surgical or bone graft-related complications. Conclusion:The safety and efficacy of 3D-printed porous bioceramic artificial bone in the treatment of limb bone defects are not significantly different from those of currently clinically applied artificial bone substitutes.

The medical records from 20 pregnant women with pregnancy preservation who underwent only cardiac surgery in our hospital from January 2012 to December 2022 were retrospectively analyzed. The patients were divided into 2 groups according to the fetal outcome: fetal survival group and fetal loss group. Eleven patients were included in fetal survival group and 9 patients in fetal loss group. The overall fetal mortality rate was 45%. In fetal loss group, 2 cases died during operation, and the other 7 cases died at 26 (29) days after operation. The valvular disease and infective endocarditis were the most common heart diseases diagnosed in fetal survival group, while type A aortic dissection in fetal loss group. There were 2 cases and 6 cases with pulmonary hypertension, 2 cases and 3 cases with a history of cardiac surgery, and 3 cases and 5 cases underwent emergency surgery in fetal survival group and in fetal loss group, respectively. Four pregnant women underwent deep hypothermic circulatory arrest in fetal loss group. One patient with type A aortic dissection died 15 days after cardiac surgery, with an overall maternal mortality rate of 5% in fetal loss group. The incidence of adverse events after maternal cardiac surgery was 25%, all of which occurred in fetal loss group. In conclusion, the adverse fetal outcomes may be related to type A aortic dissection, pulmonary hypertension, recardiac surgery, emergency surgery, deep hypothermic circulatory arrest, adverse events after cardiac surgery, and long-term related factors after surgery in pregnant women with pregnancy preservation undergoing cardiac surgery alone.

Objective: Dendrobium polysaccharide(DOP-1-1) was prepared and its effects on the proliferation, differentiation and mineralization of pre-osteoblast MC3 T3-E1 cells were investigated. Methods : A homogeneous polysaccharide(DOP-1-1) was obtained from Dendrobium officinale polysaccharide(DOP) through systematic separation and purification, and the structure of DOP-1-1 was studied by high-performance gel permeation chromatography, monosaccharide analysis, infrared spectroscopy, methylation analysis, GC-MS and NMR spectroscopy.In vitroexperiments were performed to detect the effects of DOP-1-1 on the proliferation, differentiation and mineralization of MC3 T3-E1 cells by MTT method, ALP activity determination and Alizarin Red S staining. At the same time, Western blot was used to determine the effect of DOP-1-1 on the expression of bone-related proteins(Pin1, BMP2, RUNX2) in MC3 T3-E1 cells. Results : DOP-1-1 was a homogeneous polysaccharide with relative molecular weights of 3 611, which was composed of mannose, glucose and galactose. DOP-1-1 had excellent activity of promoting osteoblast proliferation in a low concentration, and the effects of 2.0 and 4.0 μmol/L of DOP-1-1 were equivalent to Positive Control 17β-estradiol(E2). Compared with the control group, E2 and DOP-1-1(4.0, 8.0 μmol/L) increased the ALP activity and mineralization rate in MC3 T3-E1 cells(P<0.01). In particular, the ALP activity and mineralization rate of DOP-1-1(8.0 μmol/L) were higher than those of the positive control E2(P<0.001). In addition, the expression of Pin1, BMP2, and RUNX2 protein in MC3 T3-E1 cells in the DOP-1-1 group was higher than that in the control group(P<0.05). Conclusion DOP-1-1 can promote the proliferation, differentiation and mineralization of MC3 T3-E1 cells in vitro, and its mechanism is related to the activation of Pin1/BMP2 signaling pathway.
