ObjectiveTo investigate the curative effect of structural bone graft in treatment of high energy injury-induced complicated distal radius fractures combined with articular surface collapse and comminuted epiphyseal bone defect.MethodsThe study involved 38 patients with distal radius fractures (AO classification, type C3) treated from January 2007 to October 2010.The patients were treated with temporary Kirschner wire fixation to recover the wrist articular surface, distal radius length and palmar tilt angle at the greatest possibility.According to the form of the bone defects, the iliac bone taken from three layers of the cortical bone was embedded in the subchondral bone to support the bone graft, and a small amount of cancellous bone graft was collected to fill the articular surface collapse as much as possible for anatomical reduction of the articular surface, and anatomical form of the distal radius was reconstructed.Modified Sarmiento Gartland and Werley evaluation systems were used to evaluate the articular function recovery.ResultsThe follow-up lasted for 1-3.2 years, which showed no complications such as plate rupture or iatrogenic nerve blood vessels injuries.The fracture healing time was 15-22 weeks (mean 18.3 weeks).The wrist articular function in some patients obtained obvious improvement through functional rehabilitation training.According to the modified Gartland and Werley function evaluation systems, the curative effects reached excellence rate of 87％.During follow-up, there were two patients with high progressive loss in the height of the distal radius and two with articular surface collapse and severe carpal joint flexion and extension dysfunction.ConclusionsThe high energy injury-induced distal radius fractures with articular surface collapse and epiphyseal bone defect need recovery of the wrist articular surface, distal radius length and palmar tilt angle.Structural bone graft can effectively support the grafted bone and maintain the flatness of the radiocarpal articular surface, restore the anatomy of the distal radius and facilitate the functional recovery of the wrist.

Objective To study the clinical diagnosis and therapy of scar pregnancy after uterine cesarean section.Methods Clinical data of 21 patients with uterine cesarean section in our hospital from June 2006 to December 2008 were retrospectively analyzed.Results The success rate of 16 cases by drug therapy (including three cases of surgical treatment) was 81.3%;3 cases of auto-discharge transferred to other hospitals to do intervention,1 case used expectant treatment,1 case used complete curettage of uterine cavity under B-Ultrasound.Conclusion Drug treatment can terminated scar pregnancy after uterine cesarean section effectively,but there is a potential risk of massive hemorrhage or uterine rupture;color doppler ultrasound,especially Transvaginal color doppler ultrasound was the primary means of cesarean section,and benefit to judge prognostic factors and observed treatment.

Objective: To compare the efficacy of Tuina (Chinese therapeutic massage) plus physical agents and physical agents alone for lateral collateral ligament injury of ankle in gymnasts, and to explore the feasibility of Tuina for injury intervention in competitive athletes.Methods: A total of 64 gymnasts with types Ⅰ-Ⅱ lateral collateral ligament injury of ankle were selected and divided into a control group and an observation group according to a full analysis set based on the intention-to-treat principle, with 32 cases in each group. Patients in the control group received ultrasound and microwave treatment, while those in the observation group received additional Tuina manipulations. The efficacy was evaluated by total effective rate, visual analog scale (VAS) score, and American Orthopedic Foot and Ankle Society ankle-hindfoot scale (AOFAS-AHS) score. Results: The total effective rate was 96.9％ in the observation group and 90.6％ in the control group. There was no statistical difference in the total effective rate between the two groups (P>0.05). The markedly effective rate was 75.0％ in the observation group and 46.9％ in the control group. The markedly effective rate in the observation group was higher than that in the control group (P<0.05). After treatment, the VAS scores of both groups showed a downward trend, and there were statistical differences between different treatment time points in the same group (P<0.05). After one and three months of treatment, the VAS scores of the observation group were lower than those of the control group (P<0.05). There were statistical differences in the AOFAS-AHS score before and after treatment within the same group (P<0.05). After one month of treatment, there was no statistical difference in the AOFAS-AHS score between the two groups (P>0.05). After three months of treatment, the AOFAS-AHS score in the observation group was higher than that in the control group, indicating statistical significance (P<0.05). There was an interaction between time and group (P<0.05). Conclusion: Tuina plus physical agents can improve the symptoms of lateral collateral ligament injury of ankle in gymnasts. This combined treatment is superior to physical agents alone in relieving pain and improving joint functions. Therefore, Tuina plus physical agents can be used as a treatment for lateral collateral ligament injury of ankle in gymnasts.

Objective To study the current situation of chronic diseases among island residents who have drunken desalinated water for a long time， and to reveal the relationship between drinking desalinated water and water from other sources and the prevalence of chronic diseases among the population. Methods According to the different drinking water sources of island residents， the research subjects were divided into seawater desalination group （residents of Gouqi Township， Shengsi County）， mixed water source group （residents of Shengshan Town， Shengsi County） and freshwater group （residents of Huanglong Township， Shengsi County）. Through the chronic disease network report and resident health file system， the current situation of chronic diseases in different water groups was investigated and analyzed. Results There were significant differences in the prevalence of malignant tumor among drinking water sources （ χ ²=23.867， P <0.001）， with the prevalence of mixed water group >desalination group >fresh water group. There were significant differences in the prevalence of coronary heart disease （ χ ²=194.883， P <0.001）， with the prevalence of mixed water group >desalination group >fresh water group. There were significant differences in the prevalence of stroke （ χ ²=35.637， P <0.001）， with the prevalence of fresh water group > mixed water group > desalination group. There was no significant difference in the prevalence of diabetes mellitus （ χ ²=2.808， P =0.246）， but there was significant difference in the age of onset of diabetes mellitus （ χ ²=7.368， P =0.001）， and significant difference in the prevalence of diabetes mellitus in the age group ≥55 （ χ ²=17.144， P <0.001）， and the onset age and prevalence were all in the order of fresh water group > desalination group > mixed water source group. There was no significant difference in the prevalence of hypertension （ χ ²=3.962， P =0.138）， but there was significant difference in the prevalence of hypertension in the age group ≥55 （ χ ²=20.734， P <0.001）， with the prevalence of fresh water group > desalination group > mixed water source group. Conclusion Long-term consumption of desalinated water by residents is correlated with malignant tumors， coronary heart disease and stroke， and has no correlation with diabetes and hypertension.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.
