Objective To evaluate the prognostic value of China Classification System and TNM staging in patients with liver cancer undergoing resection. Methods From Jan 1986 to Dec 2000, 246 patients underwent resection of liver cancer. At least three years of follow-up was made in these 246 cases. Results The 1, 3, 5, 7, and 10-year disease-free survival rates were 55%, 30%, 25%, 20% and 18%, respectively. The 1,3,5,7,and 10-year disease-free survival rates predicted by China Classification System and TNM staging were statistically different and positively correlated with each other. Differences of survival rate between stageⅠa、Ⅰb、Ⅱa 、Ⅱb and Ⅲ by China Classification System were all statistically significant. Conclusions Based both on tumor extension and liver function, China Classification System was more accurate in than TNM stage predicting the prognosis of liver cancer patients undergoing resection.

Objective To determine the effects of health education on medication compliance and bone mineral density of patients with osteoporosis in community. Methods A total of 123 patients with osteoporosis in A and B community(64 patients in control group and 59 patients in intervention group)received diverse health education and guidance. After a 2-year intervention, knowledge of osteoporosis, health behavior, medication compliance and bone mineral density change were compared between the two groups. Results In the intervention group, the proportions of correctly responding to the questions of osteoporosis were significantly improved before and after intervention(P < 0.05), except the questions of"exercise to what extent is better". Similarly, health behavior and medication compliance were also significantly improved in the intervention group(P < 0.05). In addition, knowledge of osteoporosis, most health behavior and medication compliance were better than those in the control group(P < 0.05). The difference in the bone mineral densitybetween the intervention group and the control group before and after intervention was 0.025±0.322 and -0.139±0.312(P < 0.05), respectively, showing significant differences(P < 0.05). Conclusion Health education for patients with osteoporosis may significantly improve health behavior, medication compliance, bone mineral density, and prognosis of osteoporosis.

OBJECTIVETo study the preventive effect of Ganlong capsule on chronic alcoholic hepatic injury in rats and its mechanism.

METHODThe rat chronic hepatic injury model was induced by intragastrically administered with gradient alcohol, once a day for 12 weeks. Efforts were made to detect the content of ALT, AST, TG, CHO, TNF-alpha in rat serum and GSH, SOD, MDA, ADH, Alb in hepatic tissues were detected, conduct a hepatic pathological examination, and pathological injury grading for livers.

RESULTGanlong capsule could reduce the content of ALT, AST, TG in blood serum, MDA in hepatic tissues (P < 0.05), and enhance the activities of antioxidants such as SOD and GSH in hepatic tissues (P < 0.05). According to the liver histopathological observation, most structures of hepatic lobules in the model group were destroyed, with disordered liver cell cords, diffuse fat empty bubbles of different sizes in cytoplasm, focal necrosis and infiltration of inflammatory cells. All of treatment groups showed alleviation in rat liver injury to varying degrees.

CONCLUSIONGanlong capsule has a significant preventive effect to chronic alcoholic hepatic injury in rats.

OBJECTIVETo evaluate the prognostic value of CLIP score system for patients with resection of HCC.

METHODSA retrospective survey was carried out in 174 patients undergoing resection of HCC from January 1986 to June 1998. 153 of 174 patients with curative resection were followed up for at least three years. Disease-free survival rate was defined as the time relapsed from the date of image diagnosis and either the date of death or the date of the latest follow-up visit, with final evaluation at June 30, 2001. Recurrences were classified into early ( 3 year) recurrence. Risk factors for recurrences and prognostic factors for survival in each group were analyzed by the chi-square test, the Kalain-Meier estimation and the COX proportional hazards model respectively.

RESULTSThe 1-, 3-, 5-, 7-, and 10-year cumulative disease free survival rates were 57.2%, 28.3%, 23.5%, 18.8% and 17.8%, respectively. The associated factors with early recurrence were as fellows: tumor size > 5 cm, microsatellite, venous invasion, tumor morphology, tumor extension, advanced TNM stages, CLIP scores, radical resection, and resection margin, respectively. But both CLIP scores and Child stage were associated with late recurrence. Univariate survival curves analysis expressed that Child grades, radical resection, resection margin, tumor size, microsatellite, venous invasion, tumor morphology, tumor extension, TNM stages, and CLIP scores were associated with prognosis. The multivariate analysis by COX proportional hazards model, the independent prognostic factors for survival were radical resection, resection margin, and TNM stages.

CONCLUSIONSCLIP score, which takes into account both liver function and tumor extension, has displayed a unique superiority in predicting the tumor early and late recurrence and prognosis. It could be an useful tool in predicting the patient recurrence and prognosis with resection of HCC. Meanwhile, it may help physicians to decide the more appropriate management in advance for patients with HCC.

Objective:To discuss outcomes of emergency repairing for Gustilo III B and III C fractures of forearm with complicated tissue defects and the related influence factors.Methods:From January 2014 to Feburary 2022, data of 98 cases of Gustilo III B and III C fractures with large compound defects of soft tissue, blood vessel, bone, tendon or muscle from elbow to wrist were collected. Primary debridement, bone fixation, wound coverage by free flap, bone transfer(or bone cement filling) or dynamic reconstruction of muscle were completed with emergency surgery in Department of Hand and Foot Microsurgery, Xi'an Fengcheng Hospital. Postoperative follow-ups were conducted through outpatient clinic visits, telephone and WeChat reviews. Video clips, questionnaires and the latest information of patients were also analysed. Rank sum test and Chi-square test were used to examine the relationship between independent variables such as general condition, disease condition and surgical procedures of chimeric tissue transfer group and simple flap transfer group, together with dependent variables such as limb salvage, number of surgery, wound healing, function scores, and complications. P<0.05 were further included in the regression equation to discover the relationship between multiple independent variables and dependent variables. Results:Follow-up lasted for 6-96 months, with an average of 71.1 months. In the chimeric group, the limb salvage rate was at 95.1%, with an infection rate of 8.50% and an average number of surgery was 2.13±0.89. In the simple flap transfer group, the limb salvage rate was at 87.5%, with an infection rate of 15.38% and an average number of surgery was 2.62±0.64. The good rate of Anderson score was 65.3% and the average score of Disability of the Arm, Shoulder and Hand(DASH) was 32.9(0-60) points for all the patients. There were significant differences in dependent variables of limb salvage and infection rate between the 2 groups ( P<0.05). Ischemia time and method of bone fixation led to significant differences in number of surgery ( P<0.05). Methods of bone fixation and the types of flap made significant differences in wound healing ( P<0.05). Underlying disease, bonedefect, Gustilo classification and method of bone fixation all contributed to the significant differences in function score ( P<0.05 or P<0.01) . Conclusion:Emergency surgery for repair of serious injury of forearm has a relatively high limb salvage rate and good functional effects. The limb salvage rate is not correlated with independent variables such as severity of injury, Mangledextremity Severity Score (MESS) and ischemia time, while transfer of a simple flap or a chimeric flap is significantly correlated with the limb salvage rate, infection and wound healing. The severity of injury, ischemia time and bone defect are correlated with functional assessment, number of surgery and bone healing.

OBJECTIVEThe purpose of this study was to investigate the blood lead level of 3 - 5 year old children living in the cities in China and to provide scientific data for making policy on environmental lead pollution for children health protection.

METHODSSix thousand five hundred and two vein blood samples from 3 - 5 year old children in nineteen cities of nine provinces were sampled. Inductively coupled plasma-mass spectrometry (ICP-MS) were employed to determine lead level in whole blood after microwave digestion for sample preparation and questionnaire survey was also performed. Data were analyzed with multiple regression on factors which affecting blood lead levels.

RESULTSResults showed that mean blood lead level was 88.3 micro g/L for 3 - 5 year old children living in the cities in China and mean blood lead level of boys (91.1 micro g/L) was higher than that of girls (87.3 micro g/L). Twenty-nine point nine one per cent of the children's blood lead level exceeded 100 micro g/L. The research finding showed: (1) higher blood lead levels had negative effects on children's physical growth, language ability etc. (2) behavior of parents had certain effects on children's blood lead levels. (3) blood lead levels of children were affected by unhealthy habits.

CONCLUSIONSProblem of childhood lead poisoning in China has become more serious. During the past ten years, blood lead levels of children has been increased in China while decreasing in developed countries. Blood lead levels of children in China are higher than that of developed countries, which called for special concern by government and society.

Contrast-enhanced ultrasound (CEUS) is a new form of ultrasound (US) that can dynamically display microvessels in a highly sensitive manner. The purpose of this study was to investigate the efficacy of CEUS for characterizing testicular lesions in comparison with conventional US. Forty-seven patients with testicular lesions were enrolled. The histopathology results revealed that 31 cases were neoplastic (11 cases of seminomas, 8 nonseminomatous germ cell tumors, 8 lymphomas, 2 Leydig cell tumors, and 2 nonspecific tumors), and 16 cases were nonneoplastic (8 cases of infarctions, 3 epidermoid cysts, and 5 inflammation). The indicators of shallow lobulated morphology and cystic-solid echogenicity on conventional US were suggestive of germ cell tumors. More indicators on CEUS were found to be useful for characterizing testicular lesions. All the neoplastic lesions showed hyperenhancement on CEUS. Moreover, germ cell tumors presented with heterogeneous enhancement (73.7%, 14/19), a twisted blood vessel pattern, rapid wash-in and wash-out, and peripheral rim hyperenhancement signs. Lymphoma was characterized by nonbranching linear vessel patterns (87.5%, 7/8), rapid wash-in and slow wash-out. In nonneoplastic lesions, infarction and epidermoid cysts showed no enhancement, and abscesses were observed with marginal irregular enhancement. The sensitivity, specificity, and accuracy of CEUS for differentiating between neoplastic and nonneoplastic lesions were 100%, 93.8%, and 97.9%, respectively, and these values were higher than those for conventional US (90.3%, 62.5%, and 80.9%, respectively). CEUS can sensitively reflect the microvascular perfusion in testicular lesions and offers high accuracy for characterizing them.
