OBJECTIVETo investigate the risk factors of injuries in middle school students and to provide basis for the prevention and reduction of such incidence.

METHODS1:1 case-control study was conducted on 254 cases and 254 controls on a basis of sex, age and grade. The relationship between risk factors and injuries were analyzed by conditional univariate and multivariate logistic regression.

RESULTSSeven risk factors responsible for the incidence of injury were identified as follows: high risk behaviors (OR = 18.0600), negligence of defence (OR = 12.6455), scramble (OR = 9.6552), father being illiterate (OR = 7.7191), risky environment around their houses (OR = 5.7402), extrovert temperament (OR = 5.4707) and mother being illiterate (OR = 3.0581). We also distinguished 5 protective factors as follows: education on safety (OR = 0.2356), harmonic relation between parents (OR = 0.4941), one-child per families (OR = 0.5233), students were more knowledgeable and having positive attitude towards road traffic (OR = 0.5340) and high economy level (OR = 0.5609).

CONCLUSIONThe injuries in middle school students were caused by multiple factors, hence should carry out intervention measures to modify the influencing factors of injuries. Injury prevention and control program should focus on certain strategies such as education and supervision of environment hazards.

Objective To investigate symptom characteristics and their their prevalence in terminally ill patients with ovarian carcinoma.Methods A retrospective study was carried out based on clinical data of 98 terminally ill patients with ovarian carcinoma who died in our hospital during January 1995 to December 2004.Fifteen most common symptoms were analyzed with a focus on the followings:symptom incidence,survival time after symptom occurrence,regularity of symptom cluster,and common causes of death.Fifteen symptoms were:pain,cachexia,pleural effusion and ascites,dyspnea,fever,intestinal obstruction,renal failure,bone marrow depression,lung infection,hemorrhage,deep venous thrombosis (DVT),intestinal or pancreatic fistula,mycotic infection,jaundice and emergency conditions.Results (1)The most prevalent symptom was pleural effusion and ascites(63%),followed by pain(60%), cachexia(59%),dyspnea(52%)and intestinal obstruction(49 %).(2)The symptom which lasted longest survival time was mycotic infection(77 days),followed by intestinal or pancreatic fistula(75 days), intestinal obstruction(67 days),pain(60 days)and eachexia(60 days).Symptoms such as bone marrow depression,renal failure,dyspnea and emergency conditions were comparatively critical associated with shorter survival times(14,13,12,7 days,respectively).(3)Terminal symptoms occurred typically in clusters,with 4.9?1.5 symptoms per case.Of 98 cases,84 cases(86%)had 4 or more symptoms,with the median survival time of 63 days from the last day of anti-cancer therapy,and a slow death process.The remaining 14 cases(14%)with 3 or fewer symptoms survived only 25 days,of which 10 cases(71%)died of emergency diseases.The survival time for two groups was significantly different(P

OBJECTIVETo evaluate results of 1310 knees of meniscal treatments by arthroscopy and to present good method of meniscal treatment.

METHODSTheir age, traumatic mechanism and effects under arthroscopy were analysed in a series of 254 patients with meniscal injuries, there were 880 males and 374 females, the average of the patients was 25.5 years. The meniscal repair in 68 knee, partial meniscectomy in 756 knee, total meniscectomy in 480 knee and conservative treatment in 6 cases.

RESULTSThe patients were followed up 1 to 12 years with the average of 4 years and 3 months. The mean Lysholm score was 86.3 points in arthroscopic meniscal repair, 84.0 points in partial meniscectomy and 76.1 points in total meniscectomy. The mean Lysholm 98.7 points in all children patients with conservative treatment. They showed significant difference (P < 0.01) in the results of three treatments.

CONCLUSIONSMeniscal injuries should not cut off as it, should be repaired in 5 mm from meniscus to synovium and or partial meniscectomy. The general adoption is not the surgical operation on meniscal injuries of the child.

OBJECTIVETo discuss the reasons for the operation performed on 13 patients with upper cervical disease and to explore the management and prevention of upper cervical disease.

METHODSThirteen patients with upper cervical disease were retrospectively reviewed. The reason for of reoperations on these patients were analyzed. The measures to reduce upper cervical operational complication and bad prognosis were discussed to avoid reoperations.

RESULTSThe reasons for reoperations included 9 cases with unstable or re-dislocated atlantoaxial joint, 10 cases with residual spinal cord compression, 1 case with malposition of odontoid screw, 1 case with adjacent cervical spine regression, 1 case with occipital-cervical fusion failure, 1 case with spinal cord injury during operation, 1 case with bone-plant slipped into canales spinalis, and 1 case with demand to take out internal fixation for aggravated symptom.

CONCLUSIONSThe common reasons for upper cervical reoperations were due to instability or redislocation of atlantoaxial joint and residual of spinal cord compression. Some measures such as reducing operate miss, using firm internal fixation and decompressing were advisable to decrease the incidence of reoperations.

BACKGROUNDPulmonary embolism, a potentially fatal event, occurs more frequently in cancer patients than in the general population. To offer an accurate diagnosis and effective treatment to such patients in China, we analyzed the incidence rate and clinical features of pulmonary embolism in patients with solid tumor hospitalized in the Peking Union Medical College (PUMC) Hospital.

METHODSA retrospective analysis was made of the hospitalized patients with solid malignancies complicated with pulmonary embolism who had been admitted into the PUMC Hospital from January 2002 to December 2008.

RESULTSThe incidence of pulmonary embolism in hospitalized patients with solid malignancies was 0.27% (120/43 967). The median age at diagnosis was 57.5 years. The male to female ratio was 1.0:1.4 (49:71). Patients with non-small-cell lung cancer (NSCLC) constituted the largest proportion of the 120 patients (37.5%), followed by patients with breast (9.2%), ovarian (8.3%), pancreatic (6.7%), and liver cancer (6.7%). Eighty patients (66.7%) had stage IV cancer. Bone was the most common site of distant metastasis (46.3%). D-dimer level was elevated in 90.9% of the 66 tested patients. The incidence of bleeding due to anti-coagulation therapy was 3.6%. Thirty-six (30.0%) of the 120 patients had concurrent deep venous thrombosis in the lower extremities. Seventeen patients developed acute pulmonary embolism within 2 weeks after surgery, 3 of whom died suddenly. Four patients presented with deep venous thrombosis and 1 with pulmonary embolism prior to the identification of malignancy.

CONCLUSIONSPatients with cancer of the lung, ovarian, breast, pancreas, and liver are more likely to be complicated with pulmonary embolism than those with other types of solid tumors. Patients with distant metastasis are at a higher risk of pulmonary embolism. Pulmonary embolism without concurrent deep venous thrombosis is more frequently observed than concurrence of both disorders in the clinical setting.

Objective To study the application value of dynamic monitoring of blood pressure in the prevention and treatment of elderly hypertension. Methods 519 hypertensive patients from December 2017 to December 2018 were monitored with ambulatory blood pressure monitoring, and were divided into the elderly group (≥60 years old, 264 cases) and the control group (<60 years old, 255 cases). The results of ambulatory blood pressure monitoring in two groups were analyzed, which inclued the circadian rhythm of blood pressure, blood pressure, pulse pressure, coefficient of variation of blood pressure, blood pressure load value, average heart rate and morning blood pressure surge. Results The incidence of abnormal circadian rhythm of ambulatory blood pressure in the elderly group was 76.5%. Compared with the control group, there were differences in the indexes of diastolic blood pressure (DBP), diastolic blood pressure load value (DBPLV), pulse pressure (PP), 24 h average heart rate (24 hAHR), systolic blood pressure coefficient of variation (SBPCV), 24 h diastolic blood pressure coefficient of variation (24 h DBPCV) and morning diastolic blood pressure surge (MDBPS) between the two groups(all P<0.05). There were differences in 24 h systolic blood pressure (24hSBP), night systolic blood pressure (nSBP), night diastolic blood pressure (nDBP), night pulse pressure (nPP), day systolic blood pressure load value (dSBPLV), ninght systolic blood pressure load value (nSBPLV), 24 h SBPCV, 24 h dDBPCV and other indicators among different blood pressure types in the elderly group (all P<0.05). Conclusion Ambulatory blood pressure monitoring indicators have important guiding value for the prevention and treatment of elderly hypertension.

OBJECTIVETo study the difference in prevalence of dyslipidemia, hypercholesterolemia, hypertriglyceridemia and low blood high-density lipoprotein cholesterol (HDL-C) between the residents of urban and rural areas of varied regions in China.

METHODSFasting plasma levels of total cholesterol, triglyceride and HDL-C were determined with the enzyme methods for 49,252 subjects aged 18 and over during August to December, 2002.

RESULTSPrevalence of dyslipidemia in Chinese adults aged 18 and over was 18.6%, with 17.0%, 22.9% and 23.4% in the groups of 18-44, 45-59 and over 60 years old, respectively, 22.2% and 15.9% in males and females, respectively, and 21.0% and 17.7% in urban and rural areas, respectively. Prevalence of hypercholesterolemia, hypertriglyceridemia and low blood HDL-C in those aged 18 and over was 2.9%, 11.9% and 7.4%, respectively.

CONCLUSIONSDyslipidemia has become one of important risk factors threatening health of Chinese people, with hypertriglyceridemia and low blood HDL-C as two major types in those aged 18 and over. Prevalence of dyslipidemia was nearly the same in the middle-aged and in the elderly people, and not significantly different in those living in urban areas from those in rural areas. It is very important to pay more attention to earlier comprehensive prevention and control of dyslipidemia.

Objective To observe the effect of the intensive training of core stabilization on the general function of patients with femoral neck fractures in old patients after hip arthroplasty. Methods From January, 2011 to December, 2012, 60 old patients accepted hip arthroplas-ty for femoral neck fractures were randomly divided into control group (n=30) and observation group (n=30). The control group received routine rehabilitation training 50 minutes each time, and the observation group received intensive training of core muscles 20 minutes each time based on the routine rehabilitation training 30 minutes each time, twice a day, five days a week for two weeks. Both groups were evalu-ated with Harris Hip Score (HHS), Charnley Hip Score (CHS) and modified Barthel Index (MBI) before training and one week, two weeks and three months after training. Results There was no significant difference in the scores of HHS, CHS and MBI before and one week after training (P>0.05). All the scores increased with time in both groups (F>248.165, P<0.001). The scores of HHS, CHS and MBI were signifi-cantly higher in the observation group than in the control group two weeks and three months after training (t>3.211, P<0.001). Conclusion Early intensive training of core stabilization may facilitate to recover hip function and activity of daily living in old patients after hip arthro-plasty.
