Objective To analyze the trends in the disease burden of pertussis in China from 1990 to 2021, and to provide a basis for the development of effective prevention and control strategies. Methods Using the 2021 Global Burden of Disease Study (GBD) database, the incidence, mortality, and disability-adjusted life years (DALYs), as well as the age-standardized rates of pertussis in China from 1990 to 2021 were analyzed. Descriptive statistical methods were employed to analyze the characteristics of the pertussis disease burden, and the Joinpoint regression model was used to analyze the trends in pertussis disease burden. Results From 1990 to 2021, the incidence, mortality, and DALYs of pertussis in China decreased from 1 503 800 cases, 10 951 deaths, and 954 900 person-years to 65 400 cases, 548 deaths, and 46 500 person-years, representing a decrease of 95.65%, 95.00%, and 95.13%, respectively. The corresponding age-standardized rates also decreased by 93.58%, 92.47%, and 92.53%, respectively. The Joinpoint regression model revealed a significant downward trend in the age-standardized incidence, mortality, and DALYs rates for pertussis (AAPCs were -8.32%, -9.65%, and -9.58%, respectively, P<0.001). The disease burden was slightly higher in females than in males, with the majority of cases occurring in children under 10 years old, particularly in infants under 1 year old, where the burden was the heaviest. As age increased, the disease burden decreased. Conclusion Between 1990 and 2021, the overall disease burden of pertussis in China showed a significant downward trend, with gender and age differences. Special attention should be given on the prevention and control of pertussis in children under 10 years old, especially in infants under 1 year old.

OBJECTIVE: To observe the efficacy of "Biaoben acupoint compatibility" moxibustion for abdominal obesity and its effect on blood lipid, lipid accumulation product (LAP) and cardiometabolic index (CMI). METHODS: A total of 150 patients with abdominal obesity were randomly divided into an observation group (75 cases, 5 cases dropped out) and a control group (75 cases, 6 cases dropped out). The control group received lifestyle guidance. The observation group received "Biaoben acupoint compatibility" moxibustion at Zhongwan (CV12), Guanyuan (CV4) and bilateral Tianshu (ST25), Zusanli (ST36) on the basis of the control group, 20 min each time, once every other day, 3 times a week for 8 weeks. Before and after treatment, the waist circumference, hip circumference, weight, body mass index (BMI) were observed, the levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were measured, and the LAP and CMI were calculated in the two groups. RESULTS: After treatment, the waist circumference, weight and BMI were decreased compared with those before treatment in both groups (P<0.05), the changes of the above indexes in the observation group were larger than those in the control group (P<0.05). After treatment, the hip circumference, TC level, TG level, LAP and CMI in the observation group were decreased compared with those before treatment (P<0.05), the HDL-C level was increased compared with that before treatment (P<0.05)；the changes of the TC level, TG level, LAP, CMI and HDL-C level in the observation group were larger than those in the control group (P<0.05). CONCLUSION "Biaoben acupoint compatibility" moxibustion can reduce the degree of obesity in patients with abdominal obesity, and improve blood lipid and reduce lipid accumulation.

OBJECTIVE: To observe the efficacy and safety of moxibustion in treating patients with central obesity of phlegm-dampness constitution. METHODS: A total of 66 patients with central obesity of phlegm-dampness constitution were randomly assigned to a moxibustion group (n=33, 3 cases dropped out) and a sham moxibustion group (n=33, 4 cases dropped out). The moxibustion group received mild moxibustion combined with lifestyle intervention; the moxibustion was applied at Shenque (CV8) and bilateral Zusanli (ST36), 30 min per session, maintaining a local skin temperature of (43±1) ℃. The sham moxibustion group received simulated moxibustion combined with lifestyle intervention; the simulated moxibustion was applied at the same acupoints, with the same session length, but with a maintained skin temperature of (37±1) ℃. Both groups were treated once every other day, three times per week for 8 consecutive weeks. Obesity-related physical indicators (waist circumference, hip circumference, body weight, body fat percentage, body mass index [BMI]), constitution evaluation indicators (phlegm-dampness constitution conversion score, symptom score), the impact of weight on quality of life-lite (IWQOL-Lite), the hospital anxiety and depression scale (HADS), and the incidence of adverse events were measured before and after treatment, and after 4 weeks of follow-up. RESULTS: Compared with before treatment, both groups showed significant reductions in waist circumference, hip circumference, body weight, body fat percentage, BMI, phlegm-dampness constitution conversion score and symptom score, IWQOL-Lite, and both anxiety and depression subscale scores of HADS after treatment and at follow-up (P<0.001). These improvements were significantly greater in the moxibustion group than those in the sham moxibustion group (P<0.001, P<0.01, P<0.05). One patient in the moxibustion group experienced a mild burn that resolved with routine care; the incidence of adverse reactions was 3.0% (1/33) in the moxibustion group and 0% (0/33) in the sham moxibustion group, with no statistically significant difference (P>0.05). CONCLUSION On the basis of lifestyle intervention, moxibustion effectively improves obesity-related physical indicators, enhances quality of life, alleviates anxiety and depression, and improves the phlegm-dampness constitution in patients with central obesity. These benefits persist for at least 4 weeks after treatment.

Objective:To design an improved lamina hook system and compare its biomechanical properties with traditional lamina hook system in fixation of lumbar spondylolysis.Methods:The thin layer CT data of the lumbosacral vertebrae of 20 healthy young male servicemen who underwent physical examination in the outpatient department of the 940th Hospital of Joint Logistics Support Force of PLA from January 2021 to August 2022 were collected. The age of the subjects was 20-30 years [(25.0±3.0)years]. A 3-dimensional model of the L 5 vertebral body was constructed using the 3-dimensional modeling software. The new improved lamina hook was designed according to the measurements including the thickness of the middle area, the longest longitudinal diameter, the curvature radius of the lower edge, the angle between the upper and lower tail ends, the thickness of the lower edge, and the longest diameter of the lower edge of the bilateral L 5 vertebral plates. One serviceman was selected from the aforementioned group to construct a linear finite element model of segments L 4-S using the 3-dimensional virtual software (normal model, model A), based on which, the L 5 bilateral spondylolysis model (model B), improved lamina hook model (model C) and traditional lamina hook models (model D) were designed. By constraining both sides of the sacrum and applying a longitudinal load of 400 N on the L 4 vertebral body, the upper 1/3 gravity of the body was simulated, and with a bending moment of 10 N·m along the X, Y, and Z directions, motions of forward flexion, backward extension, lateral bending, rotation, etc were simulated. The range of motion of segment L 4/5 and L 5/S 1 of model A was evaluated and compared with the findings of the previous researches to verify its effectiveness. The overall range of motion of models A, B, C, and D, the range of motion of segment L 4/5 and L 5/S 1, the maximum overall displacement, the maximum displacement and stress of the isthmus, the stress distribution and maximum stress of internal fixation of models C and D, and the stress distribution and maximum stress of the vertebral body of models C and D were compared. Results:(1) During forward flexion, backward extension, lateral bending and rotation, the range of motion of model A was 5.01°, 4.03°, 3.91° and 1.42° in segment L 4/5, and was 4.62°, 2.51°, 2.40° and 1.23° in segment L 5/S 1. (2) The overall range of motion, range of motion of segment L 4/5 and L 5/S 1 and maximum overall displacement of models A, C, and D were similar in axial compression, forward flexion, backward extension, left bending, and left rotation, while those of model B were significantly increased. (3) There was no significant difference in the maximum displacement of the isthmus of models A, C, and D under different motion modes, while the maximum displacement of model B in the isthmus was significantly larger than that of models A, C, and D, especially during rotation, increased by 295%, 277%, and 276% respectively. The maximum stress of the isthmus of model C was 0.938 MPa, 1.698 MPa, 0.410 MPa, 2.775 MPa, and 1.554 MPa respectively. The maximum stress in the isthmus of model D was 0.590 MPa, 1.297 MPa, 0.520 MPa, 3.088 MPa, and 2.072 MPa respectively. The maximum stress of the isthmus of models C and D was similar during axial compression and forward flexion, while the stress of the isthmus of model C was smaller than that of model D during backward extension, lateral bending, and rotation, decreased by 21.1%, 10.2%, and 25.0% respectively compared with model D. (4) The maximum stress of internal fixation in models C and D during forward flexion, backward extension, left bending, and left rotation was 135.220 MPa, 130.180 MPa, 200.940 MPa and 306.340 MPa respectively, and was 131.840 MPa, 112.280 MPa, 349.980 MPa and 370.140 MPa respectively. The maximum stress of internal fixation in the two models of internal fixation during forward flexion and backward extension was similar, while it was decreased by 42.6% and 17.2% in model C during left bending and left rotation, compared with model D. (5) The maximum stress of the vertebral body during forward flexion, backward extension, left bending, and left rotation was 79.787 MPa, 36.857 MPa, 37.943 MPa and 96.965 MPa respectively in model C, but was 80.104 MPa, 64.236 MPa, 196.010 MPa and 193.020 MPa respectively in model D. The maximum stress of models C and D was all distributed in the contact area with the internal fixation, and especially during backward extension, left bending, and left rotation, when it was reduced by 42.6%, 80.6%, and 49.8% of model C respectively, compared with that of model D. Conclusions:The improved laminar hook is more consistent with the Chinese anatomized structure of the lamina. Compared with the traditional lamina hook system, the improved lamina hook system can effectively reduce the displacement in all directions and range of motion of lumbar spondylolysis, therefor can significantly reduce the stress of internal fixation and vertebral body and has better biomechanical performance.

Objective To investigate the application value of ultrasound combined with MRI in the diagnosis of fetal urinary system abnormalities.Methods The clinical data of 647 cases of fetal urinary system abnormalities suspected by prenatal ultrasound were ana-lyzed retrospectively.All pregnant women underwent MRI examination within 2 days after ultrasound examination.Using pathology and follow-up as the gold standard,the accuracy and imaging features of ultrasound and MRI in detecting fetal urinary system abnor-malities were analyzed.Results Among 600 cases confirmed by pathology and follow-up,the accuracy of MRI,ultrasound and com-bined diagnosis of fetal urinary system abnormalities were 96.50％,96.67％,97.00％,sensitivity were 95.28％,96.23％,98.11％,and specificity were 96.76％,96.76％,96.76％,respectively.There were no significant differences in accuracy,sensitivity,specificity,positive predictive value and negative predictive value between MRI,ultrasound and combined diagnosis(P＞0.05).The area under the curve(AUC)of MRI,ultrasound and combined diagnosis of fetal urinary system abnormalities were 0.960,0.965 and 0.974,respectively,with no statistical significance(P＞0.05).Conclusion Compared with prenatal ultrasound,MRI also has a higher accuracy(96.50％)in the diagnosis of fetal urinary system abnormalities,and can be used as an important supplement to prenatal ultrasound.

Objective:To evaluate the clinical effectiveness of the reconstruction of multiple digit-tip defects with transfer of polyfoliate perforator flaps of the fibular hallux.Methods:From January 2019 to June 2022, 15 patients had undergone reconstruction surgery for multiple digit-tip defects using polyfoliate perforator flaps of ipsilateral fibular hallux, with the first dorsal metatarsal artery as the pedicle, in the Department of Upper Limb Repair and Reconstruction Surgery, Guizhou Hospital of Beijing Jishuitan Hospital. The patients were 10 males and 5 females and aged 20 to 45 years old. Eight patients had the defects of thumbs and index fingers, 4 of thumbs and middle fingers, 2 of thumb, index and middle fingers and 1 of thumb, index and ring fingers. All the 15 digit injuries had nail bed defects to which reconstructive surgery were required. For the flaps of dorsal artery, flaps were 1.8 cm×2.0 cm-2.0 cm×3.1 cm in size and for those of plantar artery, the flaps sized 1.5 cm×2.0 cm-2.5 cm×3.0 cm. Donor site defects in the hallux were reconstructed with free superficial circumflex iliac perforator flaps. Postoperative follow-up lasted until 30th June 2023 and included visits to the outpatient clinic, WeChat and telephone reviews to assess the appearance, function and sensation recovery of the digits.Results:All the 15 flaps survived. During the 6 to 24 months (16 months in average) of postoperative follow-up, the appearance and texture of all flaps were found close to the healthy digits, with good nail growth and without deformity. TPD were found between 8.0 mm and 12.0 mm. The donor sites on the great toes that reconstructed with superficial circumflex iliac artery flaps were all survived well, and the incisions were satisfactorily healed without the functions of walking, running or jumping being significantly affected.Conclusion:The use of polyfoliate perforator flaps of fibular hallux for reconstruction of multiple digit-tip defects is an ideal surgical method due to the consistency of vascular anatomy, ease with flap harvest, similarity in the normal digital skin texture, and the capability to include a nail bed with the flap. A single donor from the hallux can simultaneously reconstruct two defects of digit-tip, making it an excellent treatment in the reconstruction of small-to medium-sized composite tissue defects in multiple digits.

Objective To investigate the related factors of nursing dependence in bladder cancer patients with urinary diversion and abdominal wall stoma.Methods The clinical data of 120 patients with bladder cancer undergoing abdominal ostomy with urinary diversion in the hospital from June 2020 to June 2022 were retrospectively analyzed.The self-esteem scale,the civilian version of the Post-traumatic Stress Disorder Scale,the Personal Sense of Control Scale,and the Nursing Care Dependence Scale were used to evaluate the self-esteem level,post-traumatic stress disorder level,personal sense of control level and nursing dependence degree of patients,and carry out univariate and multivariate regression analysis on the influencing factors of nursing dependence in patients with bladder cancer urinary diversion and abdominal stoma.Results The total score of nursing dependence in 120 bladder cancer patients with urinary diversion and abdominal wall stoma was 56.95±7.94.The lowest score was activity,followed by excretion and cleanliness.Univariate analysis showed that there were statistically significant differences in the nursing dependence scores of patients with different age,marital status,educational level,work status,per capita monthly income,and comorbidities(P＜0.05);the patients'self-esteem,the civilian version of the Traumatic Stress Disorder Scale,and the Personal Sense of Control Scale scores were 25.08±2.59,46.04±5.72,24.18±2.95,respectively;after multi-factor a-nalysis,it can be seen that age,education level,comorbidities,self-esteem level,post-traumatic stress obstacles and personal control finally entered the regression equation as factors influencing dependence on care for pa-tients with urinary diversion abdominal wall stoma for bladder cancer(P＜0.05).Conclusion Bladder cancer patients with urinary diversion abdominal wall stoma have the highest degree of dependence on nursing care for mobility,excretion and cleaning.Age,education level,complications,self-esteem,post-traumatic stress dis-order,and personal sense of control are related factors that affect the degree of dependence on nursing care.

Objective:To investigate the effects of case-based learning combined with clinical anatomy in neurosurgery internships.Methods:We included students in grades 2014 and 2015 (test group, n=58) and those in grade 2013 (control group, n=48) doing internships in The first Affiliated Hospital of Shantou University Medical College. The test group adopted case-based learning combined with clinical anatomy in the form of neurosurgery intern learning groups. The group learning consisting of four sessions was held twice a week for a total of four times. The traditional teaching method was used in the control group. All the students filled in the Self-Directed Learning Readiness Scale before and after neurosurgery internships. The test group filled in the Satisfaction Survey on case-based learning combined with clinical anatomy after neurosurgery internships. SPSS 20.0 was used to perform t test. Results:Before neurosurgery internships, there was no difference in self-directed learning ability between the test group and control group ( t=0.25, P=0.807). After the internships, the total score of self-directed learning ability was significantly improved in both the test group ( t=-6.49, P<0.001) and the control group ( t=-4.68, P<0.001). The test group showed improvements in six learning factors, while the control group had no significant changes in love of learning and learning motivation. Compared with the control group, the test group showed a significantly higher total score of self-directed learning ability ( t=2.17, P=0.032) and significantly higher scores of efficient learning ( t=3.81, P=0.001) and learning motivation ( t=4.20, P=0.001). The students in the test group were generally satisfied with the new method combining case-based learning and clinical anatomy. Conclusion:The new method combining case-based learning and clinical anatomy has positive effects on students' self-directed learning ability, especially on learning efficiency and motivation, with a high degree of satisfaction from the students.

Objective:To summarize the experience of 15 cases of balloon endovascular occlusion assisted aortic replacement.Methods:15 patients who needed reoperation after aortic surgery underwent endovascular balloon occlusion assisted aortic replacement by DSA guidance in the hybrid OR. Main inclusion criteria: The target vessel to be blocked cannot be directly blocked. Based on the last CTA before the operation, the diameter of the target vessel was measured, and the appropriate diameter balloon and the appropriate diameter balloon and the amount of contrast agent were selected. The vascular approach was selected according to the CTA.During the operation, the balloon was filled and fixed well, the distal invasive blood pressure waveform showed advection, and the pressure close to hydrostatic pressure as the complete blocking standard.Results:All 15 cases of balloon endovascular occlusion assisted aortic surgery were successful. After the operation, 14 target vessels normally without damage, and there was no vascular complication. One case after surgical three-branch stent surgery underwent the second thoracoabdominal aortic replacement operation. After the stent was blocked by the balloon, the new tissue in the stent fell off, and the celiac trunk and superior mesenteric artery were embolized for reoperation.Conclusion:Balloon endovascular occlusion technology expands the indications of aortic surgery and simplifies the operation, that is a safe and effective occlusion method. Whether the target vessel is suitable for balloon occlusion should be judged before the operation to avoid related complications.
