OBJECTIVE: To analyze the features of orbital fracture and to discuss its forensic expertise points. METHODS: One hundred and thirty cases of simple orbital fracture from 2010 to 2012 collected from one public security bureau were retrospectively analyzed such as age, gender, tools, position and morphology of the fracture, periorbital and orbital compound injury and the follow-up results after 6 months. RESULTS: In the 130 cases, the wounded were mainly young men and hit by fist. The fracture of simple medial orbital wall accounted for up to 81.5% in all cases. In the periorbital and orbital compound injury, laceration and contusion of eyelid and ethmoidal cellules and maxillary sinus always occurred. After 6 months follow-up, there were 30 cases of comminuted fracture remained enophthalmos compared with the uninjured side. CONCLUSION It is inappropriate to judge the fracture of simple medial orbital wall as minor injury. We should judge the degree of simple orbital fracture after the injury is stable. Detailed ophthalmology inspection is necessary for forensic expertise of simple orbital fracture.

ObjectiveTo retrospectively analyze clinical data of patients who has left-side valvular disease combined with severe tricuspid regurgitation and evaluate the effect of our modified tricuspid annuloplasty with enforcement of artificial felt strip.Methods76 patients who had left-side valvular disease combined with severe tricuspid regurgitation received operations between Jan.2008 and Jun.2010.The average age of the patients was 53.5 years old (32 male and 44 female).Besides the severe tricuspid regurgitation, other combined cardiac impairments included mitral valvar disease (52 cases), aortic valvar disease(5 cases), double valvar disease(19 cases) and left atrial thrombosis(22 cases).6 patients had grade II cardiac function according to the NYHA criteria, while 47 and 23 were in grade III and IV, respectively.Other signs included cyanosis(5cases), jaundice(11 cases), neck vein engorgement(48 cases) , ascites(22 cases), hepatomegaly(41 cases) and pitting edema in the lower limbs(68 cases).The concomitant operative procedures included mitral valve replacement in 52 patients,aortic valve replacement in 5 patients, double valve replacement in 19 patients, removal of left atrial thrombus in 22 patients,left atrium folding in 21 patients and left atrium appendage suture in 68 patients.Left-sided valve disease were corrected first,TAP was performed on the beating heart after the heart had been defibrillated.The anteroseptal commissure was plicated first.A double-armed 3-0 pledgeted suture was taken through the base of the septal leaflet, 5-6 mm from the commissure, extending along the annulus, and out from the point in the anterior annulus 10-12 mm from the anteroseptal commissure.Both ends of the suture was tied until the two Teflon pledgets approximated each other near the commissure.Then a semicircular De Vega type of plicating with a 3-0 prolene was taken, starting just from the anterior annulus near the anteroposterior commissure, and extending clockwise to a point just cephalad to the posteroseptal commissure.The suture was tied with positioning a 27-29 mm valve siser across the tricuspid valve.At last, a 3-5 mm width felt strip was prepared and was sutured to the plicated posterior annulus region with interrupted mattress sutures of 2 to 3 2-0 prolene.A favorable result was considered when TR was not marked by saline injection.Echocardiography was routinely examined one week postoperatively and patients were followed up 6 month after discharge.ResultsThere is no death in all patients.The CVP diminished significantly from 16mmHg preoperatively to 8mmHg postoperatively (P = 0.0021).The systomic pulmonary pressure diminished from 59 mmHg preoperatively to 41 mmHg postoperatively (P = 0.038).Echo one week postoperative showed no tricuspid regurgitation in 56 patients and mild in 18 patients, while 2 had moderate tricuspid regurgitation.The diameter of right atrium diminished significantly postoperatively, too.The ejection fraction was improved even though there was not significant difference as compared with preoperative data.The cardiac function of all patients improved and the signs of right heart failure were alleviated or disappeared.Follow up 1 to 36 months showed no change of the regurgitation except for one become moderate from mild when discharged.No hepatic congestion or edema was observed in all patients.ConclusionThese new modifications make the technique more selective in the remodeling of the tricuspid annulus.It could achieve better coaptation of the anterior leaflet with the others, successful annular reduction, better maintenance of the contractile property of the tricuspid ring, better distribution of pursing force in the more dilated region.It could prevent the tear of the endocardium in the posteroseptal region in the long period of time postoperatively.

BACKGROUND:The safety and efficacy of simultaneous bilateral total knee replacement or selective unilateral total knee arthroplasty in patients with severe osteoarthritis of the knees are stil controversial. OBJECTIVE:To compare safety and clinical efficacy of patients with osteoarthritis knees after simultaneous bilateral total knee replacement or selective unilateral total knee replacement. METHODS:Total y 60 cases with severe osteoarthritis of the knees (90 knees) undergoing total knee replacement were divided into unilateral total knee replacement group (n=30, 30 knees), and the simultaneous bilateral total knee replacement group (n=30, 60 knees). RESULTS AND CONCLUSION:There was no significant difference in the incidence of other complications such as infection, mortality, pulmonary embolism in patients of both groups (P>0.05). The incidence of cardiovascular complications, postoperative blood loss and blood transfusion were higher in the bilateral knee group than in the unilateral knee group (P<0.05). During fol ow-up at 1 year after replacement, no significant differences in range of motion, muscle strength of quadriceps and hospital for special surgery knee score were detected in patients of both groups (P>0.05). However, Visual Analogue Scale scores were significantly lower in the bilateral knee group than in the unilateral group (P<0.05). These data indicated that the risk of cardiovascular complications was high in patients receiving bilateral total knee replacement. Patients with severe cardiovascular disease should avoid simultaneous bilateral total knee arthroplasty.

OBJECTIVETo analyze and summarize changes of syndrome-related biological indices in acute lacuna encephalon infarction patients of upper hyperactivity of Gan yang syndrome (UHGYS), thus providing objective evidence for syndrome typing and disease identification.

METHODSRecruited were 50 patients at Department of Encephalopathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, who were in line with diagnostic criteria of UHGYS as the experimental group in this study. Another 40 healthy volunteers were recruited as the control group from May 2010 to July 2012. Blood routines (including WBC, RBC, Hb, NEUT%, and LY%), hepatic and renal functions tests (including ALT, AST, TBIL, TP, ALB, Cr, and BUN) were performed by automatic whole blood analyzer and colorimetric technique. The levels of fasting blood glucose, HbAlc, blood lipids (including TC, TG, HDL-C, LDL-C, and VLDL-C), and coagulation functions (including AT-III, PT, PTA, INR, TT, APTT, and FBG, reaction time), renin, angiotensin II, hs-CRP, and Hcy were also measured. The thyroid functions (including FT3, FT4, T3, T4, and TSH) were detected by electrochemiluminescence immunoassay. The levels of tumor necrosis factor alpha (TNF-alpha), IL-6 and IL-1 in serum were measured by ELISA and radioimmunoassay respectively.

RESULTSCompared with the control group, RBC, LY%, ALT, TP, ALB, HDL-C, AT-III activities, contents of PTA and FT4 obviously decreased, TBIL, BUN, Glu, HbAlc, TSH, hs-CRP, renin, Ang II, TNF-alpha, IL-1 and IL-6 significantly increased in the experimental group (P < 0.05, P < 0.01).

CONCLUSIONThe pathological process of acute lacuna encephalon infarction patients of UHGYS was closely correlated with thyroid functions, the renin-angiotensin-aldosterone system, the extrinsic and intrinsic coagulation systems, as well as inflammation reaction.

OBJECTIVETo explore the feasibility and safety of abdominosacral resection for patients with locally advanced primary low rectal cancer.

METHODSA total of 97 low rectal cancer patients were amenable to surgery but not anal sphincter preservation were included in this study and divided into the abdominoperineal resection group(n=49) and abdominosacral resection group(n=48) according to the order of alternative admission time between June 2010 and January 2012. Intraoperative and postoperative parameters were compared between the two groups.

RESULTSThe surgery went well and no perioperative mortality in the two groups. Compared with abdominoperineal resection group, the operative time of abdominosacral resection group(including the 2nd position adjustment time) was longer[(188±45) min vs. (143±48) min, P=0.000], the unexpected prostate or vagina injury incidence was lower [0 vs. 14.3%(7/49), P=0.032), and the perineal wound infection rate was lower [2.1% (1/48) vs. 18.4% (9/49), P=0.040].

CONCLUSIONAbdominosacral excision is feasible and safe for patients with locally advanced primary low rectal cancer.

Objective To compare the clinical diagnosis effect of high and common iodine concentration of contrast agent to patients with liver cirrhosis hepatocarcinoma in 64-MDCT.Methods Ninety patients who diagnosed with cirrhosis and hepatoma by biopsy in our hospital from January 2015 to December 2016 were randomly divided into observation group(n =45) and control group(n =45).The observation group and the control group separately accepted 350 mgI/mL and 300 mgI/mL Lohexol enhancement.The CT values of different enhanced parts,detection rate of lesions and the incidence of adverse reactions were chosen as clinical diagnosis indexes.Results The CT value of liver parenchyma,aorta and portal vein in observation group were particularly or very particularly higher than those of control group (P ＜ 0.05).145 and 110 lesions were respectively detected in observation group and control group.It showed higher diagnostic sensitivity of observation group in three phases (P ＜ 0.05) and good safety in 64-MDCT.Conclusion High concentration iodine contrast agent can remarkably improve the detection CT value and detection rate of liver cancer patients with liver cirrhosis in 64-MDCT,with less adverse reactions.

Objective To understand the current status and relative factors on knowledge, attitude, practice to contraception among college students in Beijing and to provide evidence for developing aimed contraceptive service and education in colleges. Methods Quantitative surveys were employed, questionnaire was conducted anonymously among 12 450 unmarried college students under informed consent. Results Among 12 129 students, acknowledgement of contraceptive knowledge among females was superior to males in college(P=0.000). Rates on the favor for unmarried sexual practice and 'sexual liberation' were 81.9% and 60.2% for males, comparing to 74.8% and 54.3% for females respectively. The prevalence rates for masturbation were 74.3% for males and 24.9% for females respectively. 18.4% of the male and 10.5% of the female students had ever experienced unmarried sexual intercourse. Among those students who had sexual experiences, 29.4% of the males had made their sex partners pregnant and 23.1% of the female students had experienced unexpected pregnancy. Statistical significance was found between males and females (P=0.000) in terms of attitudes and behaviors. 51.3% of the male and female students took contraceptive measures during the episode of first sexual intercourse. The excuses for not taking any measures would include: sexual intercourse happened incidentally, not interested in using condom, only one sexual experience would not cause pregnancy, etc. Conclusion The prevalence of unmarried sexual intercourse among college students had been rising. Among those who had experienced unmarried sexual intercourse, the rate of taking contraceptive measures was low and the incidence of unexpected pregnancy was high. It is urgent to strengthen the education and service programs on contraception among college students.
