Objective:To deeply analyze the epidemiological characteristics and changing trends of intestinal infectious diseases in China, and provide scientific evidence for the prevention and control of intestinal infectious diseases.Methods:The incidence data of notifiable intestinal infectious diseases in China from 2013 to 2022 were collected from China Disease Prevention and Control Information System. Descriptive statistical method was used to analyze the distributions of intestinal infectious diseases in China, and the annual change rate and seasonal index were calculated.Results:During 2013-2022, intestinal infectious diseases were reported nationwide, with the cases accounting for 43.50% of all notifiable infectious disease cases. The average reported incidence rate was 224.50/100 000, showing a decreasing trend year by year (average annual percent change=-6.45%, t=-2.76, P=0.025). The top 5 intestinal infectious diseases were hand foot and mouth disease (HFMD) (130.40/100 000), other infectious diarrhea (80.18/100 000), dysentery (7.45/100 000), acute hemorrhagic conjunctivitis (2.49/100 000) and viral hepatitis E (1.92/100 000). The incidences of dysentery, HFMD, typhoid fever/paratyphoid fever, viral hepatitis A and acute hemorrhagic conjunctivitis all showed decreasing trends year by year (all P<0.05), while the incidences of hepatitis E and other infectious diarrhea showed no significant changes with year (both P>0.05). The incidence of intestinal infectious diseases was high during May to October, with the peak in June. The incidence rate of intestinal infectious diseases was significantly higher in men than in women (all P<0.05). The HFMD, other infectious diarrhea and dysentery cases were mainly children aged 0-5 years, while the cholera, hepatitis A, hepatitis E, typhoid fever/paratyphoid fever and acute hemorrhagic conjunctivitis cases were mainly farmers aged ≥20 years. The annual reported incidence rate of intestinal infectious diseases was higher in southern provinces (283.66/100 000) than in northern provinces (142.63/100 000), and the annual reported incidence rate of intestinal infectious diseases was higher in coastal provinces (279.52/100 000) than in inland provinces (181.78/100 000), the differences were all significant (both P<0.001). Conclusions:During 2013-2022, the incidence of intestinal infectious diseases decreased significantly in China, with HFMD and other infectious diarrhea as the main diseases. Strengthened surveillance for intestinal infectious diseases should be carried out in key groups, such as children living scatteredly and farmers, and targeted prevention and control measures should be taken according to the epidemiological characteristics of different diseases to effectively reduce the incidence of intestinal infectious diseases.

The paper summarizes the authorized invention patents, device registration and the relevant published articles of acupuncture medical devices of TCM in recent 5 years, and analyzes the current status and challenges in this field. It is discovered that the optimization and substitution in diagnosis and treatment of acupuncture are involved in the development of acupuncture medical devices. The technology application of these devices are composed of traditional and emerging engineering technologies; and the theoretical guidance for their development requires the integration of traditional acupuncture principles with modern medical theories. The development of acupuncture medical devices highlights the characteristics of multidimensional integration, treatment for specific ailments, portability and wearability, painlessness and non-invasion, precision and personalization, as well as intelligent automation. Upon analysis, it is shown that in the development and product transformation of acupuncture medical devices in recent years, the theoretical principles of acupuncture of TCM have not been fully utilized yet, the transformation of patented product is low, the clinical evidence of product is insufficient, and the market competitiveness needs improvement. In the future, The theoretic guidance of acupuncture of TCM should be enhanced in the development of acupuncture medical devices, a production-education- research model with the combination of medicine and engineering be constructed, clinical verification of product be emphasized, and product development paradigms be advanced, so as to meet the demands of the medical market.

Objective:To investigate the epidemiological characteristics of lower extremity deep vein thrombosis (DVT) in patients with femoral fracture.Methods:Retrospectively analyzed were the data of 2,571 patients with femoral fracture who had been treated at the Third Hospital of Hebei Medical University from January 2019 to December 2019. There were 1,079 males and 1,492 females, aged from 14 to 96 years (average, 67.1 years). There were 1,158 femoral neck fractures, 951 femoral intertrochanteric fractures, 309 femoral shaft fractures, and 153 femoral condylar fractures. 2,414 patients were treated surgically while 157 patients non-surgically. Color Doppler ultrasonography of both lower extremities was performed to determine the occurrence of DVT before operation and every week after operation for patients undergoing surgical treatment, and within 48 hours after admission and every week during hospitalization for those undergoing non-surgical treatment. The incidence and location of DVT were recorded for different femoral fractures.Results:The incidence of DVT in this cohort was 35.5%(913/2,517), that of proximal DVT 5.3%(135/2,571), and that of distal DVT 30.3% (778/2,571). In patients with femoral neck fracture, femoral intertrochanteric fracture, femoral shaft fracture and femoral condylar fracture, the incidence of DVT was respectively 28.8% (334/1,158), 44.7% (425/951), 30.7% (95/309) and 38.6% (59/153), the incidence of proximal DVT was respectively 2.7% (31/1,158), 5.6%(53/951), 9.7% (30/309) and 13.7% (21/153), and the incidence of distal DVT was respectively 26.2% (303/1,158), 39.1% (372/951), 21.0% (65/309) and 24.8%(38/153). The incidence of DVT in the femoral vein and above, popliteal vein, tibiofibular vein and intermuscular vein in this cohort was respectively 2.3%(60/2,571), 2.9%(75/2,571), 6.4%(165/2,571) and 23.8%(613/2,571).Conclusions:The incidence of DVT may be high in patients with femoral fracture, and the proximal DVT with a high risk of pulmonary embolism may occur more in patients with femoral condylar fracture.

Objective: To investigate the clinical effect of percutaneous curved vertebroplasty in the treatment of thoracolum-bar osteoporotic vertebral compression fractures (OVCFs). Methods: All of 85 patients with single thoracolumbar vertebral OVCFs who met the admission criteria from January 2017 to July 2018 were divided into three groups according to the random dig-its table method. They were treated with percutaneous curved vertebroplasty, routine unipedicular PVP and routine bipedicular PVP respectively. There were 25 patients in the percutaneous curved vertebroplasty group, 6 males and 19 females; aged 56-80 years, with an average age of 70.6±9.7 years. Fracture vertebral body distribution: T₁₀ 2 cases, T₁₁ 4 cases, T₁₂ 3 cases, L₁ 9 cases, L₂ 3 cases, L₃ 1 case, L₄ 1 case and L₅ 2 cases. There were 32 patients in the routine unipedicular PVP group, 6 males and 26 fe-males; aged 58-75 years, with an average age of 69.5±9.3 years. Fracture vertebral body distribution: T₁₀ 2 cases, T₁₁ 4 cases, T₁₂ 5 cases, L₁ 11 cases, L₂ 6 cases, L₃ 1 case, L₄ 1 case and L₅ 2 cases. There were 28 patients in the routine bipedicular PVP group, 5 males and 23 females; aged 59-81 years, with an average age of 69.8±8.8 years. Fracture vertebral body distribution: T₁₀ 2 cases, T₁₁ 4 cases, T₁₂ 4 cases, L₁ 10 cases, L₂ 4 cases, L₃ 1 case, L₄ 1 case and L₅ 2 cases. The operation time, injected cement volume, in-traoperative blood loss were recorded and analyzed. Preoperative, postoperative 1 week and 3 months visual analogue scale scores and oswestry disability index were adopted to value the clinical improvements. Preoperative, postoperative 1 week and 3 months relative vertebral height and kyphosis correction, and the cement leakage rate were measured and analyzed. Results: There was no significant difference in the data of gender, age, VAS scores, ODI and distribution of fracture vertebrae among the three groups (P>0.05), and the baseline data was comparable. The average VAS score in the percutaneous curved vertebroplasty group was 2.3±0.5 at 1 week after surgery, that of the routine unipedicular PVP group was 2.4±0.4 and that of the routine bipe-dicular PVP group was 2.4±0.4; the average ODI in the percutaneous curved vertebroplasty group was 19.8%±3.9%, that of the routine unipedicular PVP group was 20.0%±4.1% and that of the routine bipedicular PVP group was 19.9%±3.8%; they were lower than the preoperative data, which were statistically significant (P<0.001). The average relative vertebral height in the percutaneous curved vertebroplasty group was 48.99%±9.23% at 3 months after surgery, that of the routine unipedicular PVP group was 47.11%±10.12% and that of the routine bipedicular PVP group was 46.71%±11.16%; the average kyphosis cor-rection in the percutaneous curved vertebroplasty group was 6.21%±1.94%, that of the routine unipedicular PVP group was 5.22%±2.07% and that of the routine bipedicular PVP group was 5.97%±2.09%; there was 1 cement leakage case in the per-cutaneous curved vertebroplasty group; those of the routine unipedicular PVP group were 4 cases and those of the routine bipe-dicular PVP group were 6 cases; there was no significant difference among the three groups (P>0.05). Operation time 39.10±2.00 min vs 38.70±1.70 min, injected cement volume 3.60±0.11 ml vs 3.50±0.13 ml and blood loss 5.10±0.30 ml vs 5.00±0.40 ml of the percutaneous curved vertebroplasty group and the routine unipedicular PVP group were less than those of the routine bipedicular PVP group, which were statistically significant (P<0.05). Conclution Percutaneous curved vertebroplasty could achieve satisfactory clinical outcomes for OVCFs, with advantages of less operation time, less blood loss, limited X-ray expo-sure, less injected cement volume, and more balanced augmentation for stabilization of the affected vertebrae and total verte-bral column.

Purpose To investigate the diagnostic value of prenatal MRI in fetal intracranial hemorrhage (FICH). Materials and Methods The imaging and clinical data of 41 cases of FICH accepting MRI diagnosis were retrospectively analyzed. The hemorrhage location, signal characteristics and the associated intracranial abnormalities were observed. The pregnancy outcomes and clinical data after birth were followed up. The correlation between periventricular hemorrhage/intraventricular hemorrhage (PVH/IVH) classification and clinical outcomes was analyzed by combining prenatal risk factors. Results Forty-one cases of FICH were evaluated. There were 23 cases of multifocal cerebral hemorrhage and 18 cases of single focal hemorrhage. According to the bleeding site, the 41 cases were classified into PVH/IVH (33 cases), cerebral hemispheres near cortex hemorrhage (3 cases), cerebellar hemorrhage (2 cases), subdural hemorrhage (2 cases) and subarachnoid hemorrhage (1 case). Most of the FICH cases were in subacute period (36/41) and a few were in chronic period or forming encephalomalacia (5/41). The associated changes included ventriculomegaly, vascular malformation, agenesis of corpus callosum, agenesis of vermis, etc. Follow-up results showed that there were 25 cases of labor induction (autopsy after labor induction was performed in 3 cases), 16 cases were followed-up after birth. Among the 16 newborn, there was 1 case of PVH/IVH grade II fetus showing left ear hearing loss after birth, 1 case of grade II fetus showed dyskinesia within one year after birth, and 1 case of grade IV fetus showed unilateral limb movement disorder. The other 13 cases had no obvious neurological sequelae. Spearman correlation test of ranked data indicated that PVH/IVH classification was moderately correlated with birth outcome (r=0.689, P<0.05). Conclusion Prenatal MRI can evaluate the type and severity of fetal intracranial hemorrhage, and provide references for clinical diagnosis and treatment.

Objective:To summarize our experience of retroperitoneal laparoscopic living donor nephrectomy,our continuous technical improvements and refinement of this skill and standardization of each procedure of this operation.Methods:Having approved by hospital ethical committee and local government administration,a total of 193 living donors underwent retroperitoneal laparoscopic living donor nephrectomy from Dec.2003 to Feb.2016 in our department.Under general anaesthesia,the operation was performed through 3 lumbar ports.After the kidney was liberated fully and the ureter was severed 7-8 cm under the lower pole of the kidney,the renal artery and vein were blocked with endo-cut or hem-o-lok separately and then severed.Then the kidney was taken out quickly and flushed with 4 ℃ kidney preserving fluid immediately,the donor kidneys were then preserved in iced saline until kidney transplantation.Clinical data about operation time,volume of blood loss,perioperative complications,renal function of both donors and recipients before and after operation were collected.Results:The 193 retroperitoneal laparoscopic living donor nephrectomy operations were successful with only one operation was converted to open living donor nephrectomy because of hemorrhage and unclear operation field during the operation.The average operation time was 85 min (55-135 min),the average blood loss was 60 mL (20-200 mL),and no donor needed blood transfusion during or after operation.Three donors were found to have hematoma of renal fossa after operation and none of them required further treatment.The average hospital stay after operation was 5.7 days (4-9 days).In the study,162 donors were followed up for an average of 42 months (1-58 months) and they were all healthy.Two kidney recipients had urinary bladder anastomosis leakage after operation and both needed surgical repair,a new anastomosis of ureter and bladder were made.Three kidney recipients had kidney subcapsular hematoma but required no further treatment.One kidney recipient had delayed graft function and recovered finally and the renal function of other recipients were all normal.Renal function of both donors and recipients during the follow up period were normal.Conclusion:Retroperitoneal laparoscopic living donor nephrectomy is a safe and reliable technique,it may become a standardized operation for living kidney transplantation after continuous technical improvement.Precautions must be taken to avoid complications and a skilled hand is necessary for success.
