Objective:To analyze and predict the future trend of the premature mortality of major chronic and non-communicable diseases in Anhui Province, evaluate the implementation of the "Healthy China 2030" Plan, and explore its influencing factors.Methods:Using data from death-cause surveillance and statistical yearbooks in Anhui, the trend prediction and analysis on influencing factors were conducted by using methods such as time series accumulation and logarithmic linear Joinpoint regression, principal component regression.Results:In Anhui, 28.10% of the deaths were premature ones, of which 84.40% were attributed to chronic and non-communicable diseases. In premature deaths attributed to chronic and non-communicable diseases, the deaths caused by malignant tumor and cardiovascular disease accounted for 45.88% and 41.65% respectively. The prediction results showed that the premature mortality of major chronic and non-communicable diseases would decrease in Anhui in the future, and by 2030, the goal in the "Healthy China 2030" Plan would be reached only in rural area. To reduce premature death, it is necessary to pay attention to the prevention and control of malignant tumor and cardiovascular disease. Men in urban area are the key population. Factors that reflect urban infrastructure had a significant impact on premature mortality of major chronic non-communicable diseases, such as garden and green space area per capita. Factors such as concentration of PM 2.5 had a negative impact on premature mortality of chronic non-communicable diseases, while factors such as garden and green space area per capita had a positive impact. Conclusions:Disease burden caused by chronic and non-communicable diseases, such as malignant tumor, exits in Anhui. Men in urban area are key population in the prevention and control of chronic and non-communicable diseases in the future.

Legg-Calvé-Perthes disease (LCPD) is an idiopathic necrosis of the femoral head in childhood, the deformities of the femoral head occurring in the progress of disease could result in osteoarthritis. Treatment can be surgical or nonsurgical, but the timing and indications remain unclear. Understanding of the prognostic factors of LCPD is helpful to predict the outcome and guide the clinical management. This study reviewed the literatures about the prognosis of LCPD since 2000, the prognostic factors were summarized from three categoriesas general factors, disease factors and intervention factors. The general factors were the characteristic information of patient that can be obtained at the first time clinically. The age of onset is the most definite prognostic factor, the younger the age, the better the prognosis, and 6-8 years is an important watershed. Disease factors refer to the disease characteristic information obtained through evaluation. The modified Waldenstr?m stage of the disease needs to be confirmed first, early treatment can ensure better prognosis. Then the severity was evaluated, including the involvement of necrosis, morphological changes and extrusion of the femoral head. The more severe the disease, the worse the prognosis. Most predicters, such as Catterall grading and Herring lateral column typing, have to be used in late-stage of LCPD. The degree of femoral head perfusion evaluated in enhanced MRI or DWI-MRI is an early predictor of LCPD, but it is still in the preliminary exploratory. Intervention factors are the effects of different methods of treatment on prognosis, including the comparison of surgery or non-surgery, different non-surgical and different surgical methods. The determination of surgical or non-surgical treatment mainly depends on the age of onset and severity of disease, and the younger and milder cases tend to be non-surgical treatment, but the specific indications are still controversial.

Objective To propose a new rib fracture detection network Rib-Net to automatically and accurately detect and locate rib fracture and address the issue of missed diagnosis of rib fractures. Methods The public data set RibFrac Dataset was used to evaluate the performance of the Rib-Net, and the data set was divided into training set (420 cases), validation set (80 cases), and test set (160 cases). The Rib-Net was composed of the object detection integrated network Ensemble Detection Net (ED-Ne), Complete Box Fusion (CBF) module and the segmentation network 3D Unet. Firstly, Retina Unet, UFRCNN+ and Mask RCNN were integrated to form ED-Net to predict rib fracture candidate boxes. Secondly, a new CBF module was designed to fuse overlapping fracture candidate boxes to generate candidate boxes with accurate positioning and accurate confidence. Finally, Unet was used for rib fracture segmentation to achieve further precise localization of rib fractures. Results On the “MICCAI 2020 RibFrac Challenge: Rib Fracture Detection and Classification challenge”, our proposed Rib-Net’s detection results reached the best performance, and its recall rate, free-response receiver operating characteristic curve(FROC) value and Dice were 92.3%, 0.859 and 0.61, respectively. Conclusion The Rib-Net network can efficiently and accurately detect and locate rib fractures on chest CT images, effectively assisting doctors in making accurate diagnosis.

Objective:To explore the clinical efficacy of periosteum-covered iliac crest autografts for treatment of severe osteochondral lesions of talus （OCLTs）.Methods:A retrospective case series study was used to analyze the clinical data of 26 patients with severe OCLTs treated at Zhejiang Armed Police Corps Hospital from January 2013 to October 2019. There were 21 males and 5 females，aged 17-49 years ［（36.3 ± 10.9）years］. All patients were treated using periosteum-covered iliac crest autografts. The visual analogue scale （VAS），American Orthopedic Foot and Ankle Society （AOFAS） ankle-hindfoot score and ankle joint range of motion （ROM） were assessed before operation，6 months after operation and at the last follow-up （≥ 12 months）. The area of talus injury with MRI at the same level was recorded before operation and at the last follow-up. The healing of talus and joint surface was detected with CT at the last follow-up. The healing of the incision and osteotomy site and complications were observed.Results:All patients were followed for 12 to 22 months［（15.1 ± 3.2）months］. The VAS was （2.4 ± 0.9）points and （1.7 ± 0.6）points at postoperative 6 months and at the last follow-up，significantly lower than the preoperative （5.4 ± 1.2）points （ P < 0.01）. Meanwhile，the VAS at the last follow-up was significantly lower than that at postoperative 6 months （ P < 0.01）. The AOFAS ankle-hindfoot score was （71.7 ± 7.8）points and （87.8 ± 6.2） points at postoperative 6 months and at the last follow-up，significantly lower than the preoperative （66.5 ± 7.5） points （ P < 0.01）. Meanwhile，the AOFAS ankle-hindfoot at the last follow-up was significantly lower than that at postoperative 6 months （ P < 0.01）. The ankle ROM was （58.4 ± 5.5）° and （70.0 ± 4.9）° at postoperative 6 months and at the last follow-up，significantly improved when compared to the preoperative （42.3 ± 8.1）° （ P < 0.01）. Meanwhile，the ankle ROM at the last follow-up was significantly improved when compared to that at postoperative 6 months （ P < 0.01）. The area of talus injury with MRI at the same level was 0.67（0.55，0.89）cm 2 at the last follow-up，significantly improved when compared to preoperative 2.64（1.98，3.68）cm 2 （ P < 0.01）. The transplantation had neither obvious defects nor joint surface steps based on CT findings. All surgical incisions were healed by first intention. There were no complications such as incision infection，skin necrosis，nonunion of osteotomy，malunion or severe ankle joint disorder except that 8 patients had residual local subchondral bone?marrow?edema-like?signal?and 2 patients showed delayed healing of medial malleolus osteotomy. Conclusion:For patients with severe OCLTs，periosteum-covered iliac crest autografts can effectively relieve ankle pain，improve ankle function，and reduce the area of injury.

Well water could be a stable source of drinking water. Recently, the use of well water as drinking water has been encouraged in developing countries. However, many kinds of disorders caused by toxic elements in well drinking water have been reported. It is our urgent task to resolve the global issue of element-originating diseases. In this review article, our multidisciplinary approaches focusing on oncogenic toxicities and disturbances of sensory organs (skin and ear) induced by arsenic and barium are introduced. First, our environmental monitoring in developing countries in Asia showed elevated concentrations of arsenic and barium in well drinking water. Then our experimental studies in mice and our epidemiological studies in humans showed arsenic-mediated increased risks of hyperpigmented skin and hearing loss with partial elucidation of their mechanisms. Our experimental studies using cultured cells with focus on the expression and activity levels of intracellular signal transduction molecules such as c-SRC, c-RET, and oncogenic RET showed risks for malignant transformation and/or progression arose from arsenic and barium. Finally, our original hydrotalcite-like compound was proposed as a novel remediation system to effectively remove arsenic and barium from well drinking water. Hopefully, comprehensive studies consisting of (1) environmental monitoring, (2) health risk assessments, and (3) remediation will be expanded in the field of environmental health to prevent various disorders caused by environmental factors including toxic elements in drinking water.

Objective: To investigate the relationships of intracranial compartment volumes with the severity of clinical symptoms before surgery, and the degree of symptom improvement one year after cerebrospinal fluid(CSF)shunt surgery in patients with idiopathic normal pressure hydrocephalus(iNPH). Methods: Twenty-one patients meeting the diagnosis criteria of international guidelines of iNPH and undergoing CSF shunt surgery in Department of Neurosurgery in our hospital from 2016 to 2017 were included.All patients underwent brain MRI measurement before surgery, and were evaluated by using 3-meter timed up and go test(TUG), minimum mental state examination(MMSE), idiopathic normal pressure hydrocephalus grading scale(iNPHGS)and modified Rankin scale(mRS)before and one year after CSF shunt procedures.The ventricular volume, brain volume, pericerebral CSF volume, total intracranial volume and Evans' index were measured in the pre-operative imaging of the brain.The following four pre-operative intracranial compartment volumes were calculated: the relative ventricular volume, brain volume ratio, pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume. Results: The scores of gait, cognitive function and urinary function were improved after surgery in iNPH patients(all P<0.05). There were no significant difference in the correlation of intracranial compartment volumes(the relative ventricular volume, brain volume ratio, pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume)and Evans' index with the severity of clinical symptoms including gait, cognitive function and urinary function before surgery, and with the degree of symptom improvement one year after surgery in iNPH patients(all P>0.05). There was no significant difference in intracranial compartment volumes between patients having improvement in mRS, TUG, MMSE and iNPHGS and patients having no improvement one year after surgery in iNPH patients(all P>0.05). Conclusions Patients with iNPH can benefit from CSF shunt surgery and have improvements of clinical symptoms including gait, cognitive function and urinary function.Preoperative intracranial compartment volumes(the relative ventricular volume, brain volume ratio, pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume)and Evans' index have no correlations with the severity of clinical symptoms before surgery, and have no correlations with the degree of symptom improvement one year after surgery in iNPH patients.For this reason, preoperative intracranial compartment volumes and Evans' index cannot be used to predict whether or not CSF shunt surgery can improve specific clinical symptoms.

OBJECTIVE: To evaluate the efficacy of decitabine combined with low-dose CEG regimen (DCEG) and decitabine combined with low-dose CAG regimen (DCAG) in the treatment of elderly patients with MDS and MDS-transformed acute myeloid leukemia (AML). METHODS: A prospective study was conducted in 7 medical centers, 45 patients with MDS (≥ 60 years old) and MDS-transformed AML from October 2016 to January 2019 were enrolled, with the median age of 68.5 years old. The risk stratification of patients was poor or very poor, according to IPSS-R score. The treament results of decitabine combined with CEG and decitabine combined with CAG were compared. RESULTS: The comparison of the two regiem showed that the DCEG regimen had advantages on total effective rate (ORR, 86.4% vs 47.8%, respectively), overall survival time (OS) (10.0 months vs 6.0 months, respectively) and progression-free survival time (PFS) (9.0 months vs 3.0 months, respectively). About 50% of MDS patients treated by DCEG regimen achieved PR or CR, with a median OS of 31 months. Multivariate analysis showed that patients with PR or CR after induction therapy and DCEG regimen had longer survival time (31months). The incidence of bone marrow suppression, infection and treatment-related mortality rate were similar between the two groups. CONCLUSION Decitabine combined with CEG regimen could improve the survival of patients with high-risk MDS and MDS-transformed AML. The conclusion of the reaserch needs to be validated by a larger prospective randomized clinical trial.

Objective: To evaluate the accuracy of transarticular screw fixation using intraoperative three-dimensional fluoroscopy-based navigation (ITFN) and to evaluate the clinical outcomes of this treatment method. Methods: Data of 56 patients(26 males and 30 females) with atlantoaxial instability who were treated by C_{1, 2} transarticular screw fixation using ITFN from November 2005 to October 2015 were retrospectively analyzed. The mean age of the patients was 44.5 years (range, 9-68 years). There were 44 cases with congenital malformation, 4 with old odontoid fracture, 7 with spontaneous dislocation, and 1 with rheumatoid arthritis. C₂ isthmus width and height were measured on preoperatively obtained CT scans, and screw positioning was evaluated on postoperatively obtained CT scans, and classified into three types: ideal position (type I), acceptable position (type II) and unacceptable position (type III). A novel grading system is proposed based on previous study and grading system, and the difficulty of placing C_{1, 2} transarticular screw using ITFN was classified into three types: easy (total score 0), median (total score 1) and hard (total score 2, 3). Pain scores were assessed using the visual analogue scale. Myelopathy was assessed using the Nurick scale and Odom’s criteria. Results: The isthmus width was 5.46±1.86 mm on the right side and 5.38±1.36 mm on the left side. The isthmus height was 4.89±1.33 mm on the right side and 4.97±1.17 mm on the left side. According to the grading system, 78, 11, and 23 of the sides were classified into easy, median and hard groups respectively. One hundred and seven transarticular screws were placed in 56 patients, and 71.03% of which were ideal screws, and 28.97% were acceptable screws. Five patients had unilateral screws placed. There was no significant difference in screw positioning among the three groups (χ²=0.46, 0.54, 1.18; P=0.50, 0.46,0.28). The mean follow-up period was 44.7 months (range, 6-120 months). At the latest follow-up, according to Nurick score, there are 30 patients scoring 0, 25 patients scoring 1, and 1 patient scoring 2. According to Odom’s criteria, outcomes were as follows: excellent, 66.1%; good, 26.8%; fair, 7.1%; and poor, 0%. All patients with preoperative neck pain had symptom relief or improvement, with more than 89.33% improvement in visual analogue scale scores. No dural laceration, injury to the vertebral artery, spinal cord, or hypoglossal nerve were noted. Conclusion ITFN is a safe, accurate, and effective tool for transarticular screw placement in patients with atlantoaxial instability.

Objective: To investigate the clinical value of gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery on patients with cholecystolithiasis. Methods: A retrospective study was performed on data of 15 patients with cholecystolithiasis, who underwent gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery from April 2018 to July 2018. The operative data, including situation of operation, operative time, intraoperative hemorrhage, and postoperative complications were recorded. Results: The procedure was performed successfully in all patients with a mean operative time of 108±12 min (ranged from 92-129 min). The intraoperative hemorrhage was 10-30 mL. Eight patients suffered from slight right upper abdominal pain, and 7 patients felt slight pain in umbilical a week after surgery. No fever, incision infection, umbilical hemia, peritonitis, and ascites were reported. The clear-liquid diet was recommended for one day after operation, and postoperative activity was allowed since the second day after operation. All patients were discharged on the fourth or fifth day, and all recovered to their normal life at one week after discharge. Follow-up showed that the scar was small and hidden in umbilical without visible incision after one month. Ultrasonic examination results showed that gallbladder contractile function worked perfectly in four patients and no gallbladder stone was found after three months. Conclusion Gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery is a safe and effective option for patients with cholecystolithiasis, provides excellent cosmetic outcomes, and can be appropriately carried out under the strict control of surgical indications.
