Objective To explore the relationship between the post-thoracotomic wound infection and nutritional status.Methods The patients treated with thoracotomy were divided into the simple wound infection group(n=15) as the experimental group and the phase Ⅰ healed group (n=15) as the control group.On the fifth day after operation, the sero-albumin quantity and cumulative nitrogen balance were recorded respectively. The statistical data were given the test.Results Every average index of sero-albumin in the experimental group was lower than the control group. Among them, the total protein comparison had statistical significance (P0 05) and transferrin comparison had statistical difference (P

Objective:
To evaluate the safety and effectiveness of ultrasound-guided percutaneous nephrolithotomy (PCNL) accessed by SVOF-principle and two-step puncture techniques.
Methods:
A total of 838 cases with upper urinary stones underwent percutaneous nephrolithotomy successfully accessed by ultrasound-guided between June 2007 and December 2015 at Department of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. Of all cases were divided in two groups: hydronephrosis calyces puncture group include 425 cases and SVOF-principle puncture group include 413 cases. The access establishment time, operation time, stone free rate (SFR), postoperative complications, and postoperative hospitalization time between the two groups we compared by

OBJECTIVETo compare the effect of bone regeneration with two different ratios of nano-hydroxyapatite(nHA)/collagen(Col) (nHAC) after tooth extraction in canine.
METHODSTwo kinds of nHAC grafts were prepared with different nHA/collagen ratio of 3∶7 and 5∶5. Eighteen male healthy adult dogs had been randomly divided into three groups. Immediately after extraction of the mandibular second premolars, each kind of nHAC was implanted into extraction sockets as follow: Group A, nHA/Col=3∶7(12 sites); Group B, nHA/Col=5∶5(12 sites); Group C, blank control group(12 sites). The bone repairing abilities of the two grafts such as vertical distance of alveolar, CT values, general observation, histological observation, trabecular volume fraction and porosity were separately analyzed at 1st, 3rd and 6th month, respectively (each group had 4 sites in different time periods).
RESULTSnHAC were absorbed gradually after they were implanted into alveolar bone defect and were replaced by new bone. The vertical distance of alveolar bone in Group A([15.76±0.28] mm) was significant higher than that in Group B([14.88±0.36] mm), and CT values of Group A([879±31] HU) were higher than those in Group B([718±29] HU) (P<0.05). The trabecular bone volume percentage of Group A([22.2±0.4]%) was higher than that in Group B([20.3±0.4]%), and the bone porosity of Group A([23.6±0.9]%) was lower than that in Group B([27.6±0.6]%) (P<0.05). In addition, the vertical distance, CT values and the trabecular bone volume percentage of Group C was lower than those in Group A and B, but the bone porosity of Group C was higher.
CONCLUSIONSThe nHAC with nHA/collagen ratio of 3∶7 could better promote bone regeneration than nHAC with the nHA/collagen ratio of 5∶5 did.

Objective To evaluate the accuracy and clinical significance of the vesical imagingreporting and data system (Ⅵ-RADS) in predicting muscle-invasive bladder cancer (MIBC).Methods The data of 59 bladder cancer patients who underwent multiparametric magnetic resonance imaging and surgery between 2014 March and 2019 May were retrospectively analyzed,which includes 51 males and 8 females,aged 36-82 years old,with a median age of 62 years old.According to the scoring methods specified by Ⅵ-RADS,radiologists read and scored all mpMRIs including T2-weighted imaging (T2WI),diffusion-weighted imaging(DWI),and dynamic contrast enhancement MRI(DCE-MRI) of all the included patients.And then the Ⅵ-RADS were compared with pathological diagnosis.Proportions of MIBC in each score category were calculated,and ROC curve was plotted and the area under the curve (AUC) was estimated to assess the sensitivity and specificity of Ⅵ-RADS in diagnosing MIBC.Results The number of patients in Ⅵ-RADS score category 1 to 5 were 12,28,2,15 and 2,respectively.And there were 0,2 (7.4%),1 (50.0%),13 (81.3 %),2 (100.0%) MIBC patients in each score category,respectively.When Ⅵ-RADS ≥3 was used to define MIBC,it came to the largest Youden's Index(0.7913),with an AUC of 0.924.And the sensitivity and specificity were 88.9% and 90.2%,respectively.Conclusions Ⅵ-RADS has high accuracy in predicting MIBC,and it is worthy of application and verification in further clinical practice.The urologists should be highly alert to the existence of MIBC when Ⅵ-RADS ≥3.

BACKGROUNDBased on the excellent medical care and management system for Chinese veterans, as well as the detailed medical documentation available, we aim to construct a Chinese Veteran Clinical Research (CVCR) platform on non-communicable diseases (NCDs) and carry out studies of the primary disabling NCDs.
METHODSThe Geriatric Neurology Department of Chinese People's Liberation Army General Hospital and veterans' hospitals serve as the leading and participating units in the platform construction. The fundamental constituents of the platform are veteran communities. Stratified typical cluster sampling is adopted to recruit veteran communities. A cross-sectional study of mental, neurological, and substance use (MNS) disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment, followed by systematic neuropsychological assessments to make clinical diagnoses, evaluated disease awareness and care situation.
RESULTSA total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform, yielding a response rate of 83.86%. 8 812 subjects complete the MNS subproject screening and total response rate is 91.70%. The average participant age is (82.01±4.61) years, 69.47% of veterans are 80 years or older. Most participants are male (94.01%), 83.36% of subjects have at least a junior high school degree. The overall health status of veterans is good and stable. The most common NCD are cardiovascular disorders (86.44%), urinary and genital diseases (73.14%), eye and ear problems (66.25%), endocrine (56.56%) and neuro-psychiatric disturbances (50.78%).
CONCLUSIONWe first construct a veterans' comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans. The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.
