OBJECTIVETo study the epidemiology of births in urban China.
METHODSA retrospective study was conducted on neonates born in 2005 in the maternity departments of 72 urban hospitals from 22 provinces in China.
RESULTSA total of 45722 infants born between January 1, 2005 and December 31, 2005 were enrolled. The male to female sex ratio was 1.13:1. Preterm births accounted for 8.1%. The incidence of very low birth weight infants was 0.7%. A total of 99.7% of mothers delivering at term had conceived naturally and 0.3% had experienced assisted reproduction. A total of 98.4% of mothers who delivered preterm had conceived naturally and 1.6% had experienced assisted reproduction. The proportion of vaginal deliveries was 50.8% compared to 49.2% delivered by cesarean sections. Many cesarean sections (38.1%) were due to social factors. Infants with an Apgar score≤7 at 1 minute accounted for 4.8%, and 1.6% of infants had an Apgar score≤7 at 5 minutes. Of all the infants included in the study, 7.14% were admitted to neonatal units for treatment. The death rate of all included infants was 0.74%.
CONCLUSIONSThe proportion of preterm births was higher in 2005 than in 2002-2003. The proportion of cesarean section deliveries was much higher in urban China than in most other Asian countries and America.

OBJECTIVETo study the main risk factors of low back pain of workers ina foundry factory of the automobile company using cross sectional epidemiological investigation, and to provide scientific base for preventing the disorder.
METHODSThe low back pain and work loads of 1340 workers in a foundry factory of the automobile company were investigated using questionnaire, and logistic regression analysis was used to analyze the risk factors.
RESULTSThe one-year morbidity of low back pain in workers was 58.9% the morbidities of low back pain in workers engaged in foundry, transportation and modeling were 64.6%, 64.6% and 62.5%, respectively. The lifting with squat postures, bending trunk heavily, bending trunk with twisting and moving the heavy objects were found to be the most dominant risk factors for low-back pain, the OR values were 2.085, 1.961, 1.967 and 1.956, respectively. The distributions of risk factors were different among the different jobs. The logistic regression analysis showed that moving the heavy objects, lifting with squat postures, bending trunk heavily, bending trunk with twisting existed simultaneously, also the work years and gender were the risk factors.
CONCLUSIONThe manual moving heavy objects, awkward working posture or both were the most important risk factors for low-back pain. The intervene ergonomic study should be performed in future to reduce the morbidity of low-back pain.

Anti-H antibody belongs to IgM type cold antibody, which often induces the unconformity of positive and reverse typing and leads to the difficulty in clinical blood typing. Anti-H antibody was found during identification of the counter blood group in 3 cases. The antibody was found to be active at 37 degrees C, room temperature and 4 degrees C when determined by blood group serology, and was finally analyzed to be IgM. It is suggested that not to give erythrocytes of O group unreasoningly to blood recipient of AB group during emergent moment, but instead, to give same type of blood. If there was no same type of blood during urgent events, O type erythrocytes could be employed after being matched by saline centrifuging with host side coincidence and screened by incomplete method. In this case, anti-H antibody leading to adverse-reaction in blood transfusion should be prevented.

OBJECTIVETo evaluate the correlation between different therapies and survival of liver metastasis from colorectal cancer ( LMCC) , and to compare the clinical outcome of synchronous liver metastasis (SLM) with that of metachronous liver metastasis (MLM).
METHODSThe clinical data of 363 patients with LMCC were retrospectively reviewed with focus on the correlation between different therapy and survival.
RESULTSOf these 363 patients, 160 had SLM and 203 had MLM. Between the SLM and MLM group, there was no significant difference in age, or gender or primary cancer site (P > 0. 05 ), but significant differences were observed in condition of liver metastasis including liver lobe involved, focus number, maximum focus diameters and level of serum CEA and CA199 before therapy(P <0. 05). Ninety-one patients underwent curative hepatic resection, 22 of them in the SLM group and 69 in the MLM group. Mortality rate related to operation was 4. 5% (1/22) in SLM group and 2. 9% (2/69) in MLM group( P < 0.05). All patients were followed until 31/6/2005. The 3-year survival rate was 5. 2% with a median survival time of 10 +/- 1 months for the SLM group, and it wasl6. 4% and 17 +/- 1 months for the MLM group (P<0.01). Regarding to the treatment modalities, the 3-year survival rate was 30. 2% with a median survival time of 26 months for curative hepatic resection group, and it was 0% - 16. 7% and 10 - 17 months for non-operation groups treated by intervention, chemotherapy, radiofrequency therapy, percutaneous ethanol injection and Chinese traditional drugs (P <0. 05, P <0. 01 ).
CONCLUSIONCurative hepatic resection is still the first choice for liver metastasis from colorectal cancer improving the survival significantly. Other non-operative methods also can improve phase II resection rate. Metachronous liver metastasis has higher resection rate and better survival than the synchronous liver one.

BACKGROUND: Posterior screw rod system reduction and internal fixation is often used to treat thoracolumbar fractures (T11-L2). However, the "shell" phenomenon is focused on imaging findings and lacks of in-depth clinical research. OBJECTIVE: To explore the new method of "shell" volume measurement of vertebral body after thoracolumbar fractures reduction, and to evaluate the effect of different "shell" sizes on clinical treatment. METHODS: From January 2013 to December 2015, 72 patients with thoracolumbar fractures were treated in the No. 4 People's Hospital of Zigong City retrospectively. The patients with vertebral "shell" were retrospectively analyzed. Clinical and imaging data (X ray, CT and MRI) were collected. Compression degree of anterior border of the vertebral body, Cobb angle, Visual Analogue Scale score and reduction-related complication were recorded and analyzed. The volumes of vertebral "shell" and the injured vertebral body were measured by Mimics software. The volume ratio of shell/injured vertebral body was calculated. The healing of vertebral "shell" was followed up and observed. RESULTS AND CONCLUSION: (1) Among the 72 patients, there were 16 cases with a shell/injured vertebral volume ratio of < 5% (group A), 30 cases with the volume ratio of 5%-10% (group B), and 26 cases with volume ratio of > 10% (group C). (2) The "shell" healing: The "shell"nonunion rate was significantly lower in the groups A and B than in the group C (P < 0.05); and significant differences were not determined between groups A and B (P > 0.05). (3) Compression degree of the anterior border of the injured vertebral body: No significant difference was found in groups A, B and C before and right after reduction (P > 0.05). The compression was significantly higher in the groups A and B than in group C at final follow-up (P < 0.05). (4) Cobb angle was not significantly different in groups A, B and C before and right after reduction and during final follow-up (P > 0.05). (5) Visual Analogue Scale score was not significantly different between groups A and B and group C right after reduction (P > 0.05). The Visual Analogue Scale score was significantly better in the groups A and B than in the group C (P < 0.05). (6) Occurrence of complications: In the group A, one case affected incision exudate. In the group B, one case experienced incision infection and one case suffered from screw loosening. In the group C, two cases affected screw loosening, and one case experienced unilateral connecting rod fracture. No significant difference in complications was detected among groups A, B and C (P > 0.05). (7) Results indicate that the "shell"nonunion rate was high when vertebral shell/injured vertebral body volume ratio > 10%; loss of posterior vertebral height and chronic lumbago and back pain easily appeared. The measurement of the volume of vertebral "shell" plays an important role in clinical prognosis and treatment options of thoracolumbar judgment.
