Objective To find out if apoptosis is induced after intra-radiotherapy and its effects on pericarcinomal tissue. Methods From 1994 to 1998, 44 patients with unresectable liver cancer received 32 P-GMS intra-radiotherapy. After 2 to 6 months the tumors in 3 cases could be resected and we used this cases as the treatment group. We use 4 patients with resectional HCC of same age, diseased region, differentiated but without anyother therapy as the control group. The TUNEL staining was used to stain the resected tissue, and the apoptosis index was counted. Results The apoptosis index of carcinoma was 29%～34%, average (31?16)% in the treatment group and that of the control group was 4%～6%, average (5?12.2)%. The apoptosis index of pericarcinomal tissue was 27%～37%, average (35?11)% in the treatment group and that of the control group was 0.3%～5%, average (4.1?3.3)%. Conclusion 32 P-GMS intra-radiotherapy can enhance the apoptosis of HCC and its adjacent tissue.

Objective To investigate the effect of Amikacin and prulifloxacin alternate application in the treatment of Lung infections in ICU resistant Acinetobacter Bauman.Methods 82 cases of Lung infections in ICU resistant Acinetobacter Bauman from August 2014 to August 2016 in our hospital were selected and randomLy divided into two groups, 41 cases in control group were given routine treatment, 41 cases in the experimental group were treated with Amikacin and prulifloxacin alternate application, and patients were treated continuous for two weeks.Levels of serum CRP, PCT, WBC, N%, SCR, BUN, AST, ALT, scores of APACHE II and CPIS and clinical efficacy were observed pre-and post-treatment.Results After two weeks, levels of serum CRP, PCT, WBC and N% in experimental group were significantly lower than control group, scores of APACHE II and CPIS were significantly lower than the control group, the total clinical efficiency was higher than the control group(P<0.05), and the levels of serum SCR, BUN, ALT, AST were lower, but had no statistically difference.Conclusion Amikacin and prulifloxacin alternate application in the treatment of Lung infections in ICU resistant Acinetobacter Bauman can reduce the patient's inflammatory reaction and the degree of infection.

Objective To evaluate the value of 18F-FDG PET/CT in preoperative diagnosis and staging of suspected extrahepatic cholangiocarcinoma (EHCC).Methods The clinical data of 116 patients (72 males,44 females;age range 26-89 years) with suspected EHCC from January 2013 to October 2014 were retrospectively analyzed.All patients received preoperative whole body 18F-FDG PET/CT scan.The imaging results were compared with final clinical diagnosis.The diagnostic sensitivity,specificity,positive predictive value,negative predictive value and accuracy of 18F-FDG PET/CT were calculated.Two-sample t test was applied to compare lesion SUVmax of malignant and benign diseases.One-way analysis of variance was applied to compare SUVmax of highly,moderately and poorly differentiated tumors.x2 test was used to compare the difference of diagnostic sensitivities for hilar cholangiocarcinomas and common bile duct tumors.Results All patients were confirmed by exploratory laparotomy and subsequent histologic examination.A total of 94 cases (93 adenocarcinomas and 1 squamous carcinoma) were confirmed malignant and 22 cases (11 biliary calculi,9 cholangitis,1 choledochal cyst,1 tuberculosis) were confirmed benign.The diagnostic sensitivity,specificity,positive predictive value,negative predictive value and accuracy of 18F-FDG PET/CT for primary tumor were 61.7％ (58/94),77.3％ (17/22),92.1％ (58/63),32.1％ (17/53),64.7％ (75/116),respectively.The diagnostic sensitivity and specificity for regional lymph node metastasis were 45.5％(15/33),91.4％(53/58),and those for distant metastasis were 3/4,94.3％(82/87).The SUVmax of malignant tumors were higher than that of benign lesions (4.57± 3.75,2.72± 2.48;t =2.83,P＜ 0.05),while the differences of SUVmax among highly,moderately and poorly differentiated tumors were not significant (4.89±4.75,4.23±2.49,4.47±2.73;F=0.269,P＞0.05).18F-FDG PET/CT showed a lower sensitivity in hilar cholangiocarcinomas than that in common bile duct tumors,while no statistical significance was observed:48.6％ (17/35) vs 69.0％ (40/58),x2=3.827,P＞0.05.Conclusions The value of 18F-FDG PET/CT in preoperative diagnosis and staging of EHCC is limited.It can distinguish some benign diseases from malignant tumors,but with higher false positive for cholangitis.It can help to adjust treatment strategies by detecting distant metastasis.

Objective To observe the clinical efficacy of Xiezhuo Zhubi Decoction combined with Etoricoxib for the treatment of acute gout arthritis.Methods Seventy acute gout arthritis patients were randomly divided into treatment group and control group,35 cases in each group.Based on the fundamental treatment,the control group were given oral use of Etoricoxib and the treatment group was treated with Xiezhuo Zhubi Decoction combined with Etoricoxib.The treatment for both group lasted for 7 days.Before and after treatment,the changes of blood uric acid,C-reactive protein and erythrocyte sedimentation rate in both groups were observed.After treatment,the clinical efficacy was evaluated,and the toxic and adverse effects were also monitored.Results (1) In the treatment group,the total effective rate was 91.4％;in the control group,the total effective rate was 71.4％.There were significant differences between the two groups(P ＜ 0.05).(2) After treatment,blood uric acid,C-reactive protein and blood sedimentation rate were much improved in both groups (P ＜ 0.05 compared with those before treatment),and the treatment group had better effect on improving blood uric acid and C-reactive protein(P ＜ 0.05).(3) The control group had 3 cases of nausea,while no adverse reactions occurred in the treatment group.Conclusion Xiezhuo Zhubi Decoction combined with Etoricoxib is effective for the treatment of acute gout arthritis,and its effects on relieving clinical symptoms and decreasing blood uric acid and erythrocyte sedimentation rate are better than Etoricoxib alone.

ObjectiveTo explore the effect of the calcium phosphate cement (CPC) /calcium polyphosphate fiber (CPPF) composites mixed with different proportion of minimal morselized bone on repair of bone defect in vivo. MethodsA total of 36 New Zealand white rabbits were completely randomly designed into A, B, C, D groups and their bilateral radial bone defect model was prepared. The minimal morselized bone (300-500 μm in diameter) was made from the iliac of those rats. The CPPF and CPC were evenly mixed into CPC/CPPF composites which were divided into four groups in accordance with the CPPF weight O, 10％, 30％ and 50％ in CPC/CPPF composite. The CPC/CPPF composites of the four groups was mixed with the minimal morselized bone with ratio of 6:4 and then the mixture was implanted the bone defect of the rabbits in four groups. The gross, X-ray and histological observations were done at four and eight weeks. The biomechanical test was performed at eight weeks. Results When CPPF occupies 30％ of the CPC/CPPF composite, the maximum compressive load and bending loads were better than those in the other groups ( P ＜ 0.05 ), when the histological observation showed the most tight link between the artificial composite and the bone interface and the closest similarity between material degradation rate and the ossification rate, with the best osteogenesis and the optimal ratio.ConclusionThe repair of bone defect can attain the optimal outcome through adding a certain ratio of minimal morselized bone into the CPC/CPPF to adjust the degradation rate of composites.

OBJECTIVE To investigate the incidence of the mitochondrial DNA 12SrRNA A1555G and connexin 26 gene (GJB2) in Chinese northwest population with nonsyndromic sensorineural hearing loss,and to explore the relationship between mitochondrial DNA A1555G and mutation of GJB2 gene. METHODS Blood samples were obtained from 221 patients with nonsyndromic sensorineural hearing loss in Northwest of China; Genomic DNA was extracted from the isolated leukocytes ; Screening the mitochondrial A1555G mutation by PCR-Alw26l digestion and sequence analysis, PCR and direct sequencing were used to analyze the coding region of GJB2 gene. RESULTS The homoplasmic A1555G mutation was found in 21 individuals of 221 patients,17 of these 21 patients had been treated with aminoglycosides. Eleven different variants of GJB2 were found in all patients ,the disease-causing mutations of GJB2 were 44 individuals in these patients(44/221), The mutation 235delC is found in 54.54 % of all disease-causing mutations ; Among 21 patients with the A1555G mutation, 11 cases were found polymorphic change in GJB2 gene ,only 1 case had V37I heterozygous mutations ,other 9 cases were not found any nucleotide changes of GJB2 gene. CONCLUSION The mtDNA 12SrRNA A1555G mutation has a high incidence in Chinese northwest population with non-syndromic sensorineural hearing loss.The 235delC mutation in the GJB2 gene is most frequent mutations responsible for non-syndromic hearing impairment in this region .It is unlikely that the GJB2 gene is a major modulatory factor for hearing loss due to the A1555G mutation in Chinese population.

Objective To analyze the clinical characteristics and treatment strategy of phosphaturic mesenchymal tumors in hips.Methods From May 2017 to November 2017,five patients with phosphaturic mesenchymal tumors in hips,who treated in our hospital were retrospectively reviewed.The clinical manifestations,laboratory inspection,radiological examination,pathological examination and treatment were analyzed.Results Two male cases (40％) and 3 female (60％) were included.The overall age was 49～63 years old (average 54.40±5.37 years old).The course was 19～101 months (average 51.20±32.41months).Four cases of tumor were located in femoral head and 1 case was in femur intertrochanteric region.The maximum tumor diameter was 0.76～1.83 cm (average 1.28±0.39 cm).The early clinical manifestations of the patients were mainly non-specific bone pain or fatigue.The symptoms of the hip were not obvious.All patients had been misdiagnosed.After pathological frac-ture of the hip,the patient suffered from hip pain,thigh pain,fatigue,etc.,or limited hip function.The severe patients had a systemic multiple pathologic fractures.The serum phosphorus was lower than normal in preoperative period and recovered to normal level in 3-8 days after surgery.The postoperative ALP decreased significantly than preoperative in 4 patients and 1 case was slightly higher than preoperative.Preoperative 1,25-(OH)2-D3 and PTH were in normal range.99Tcm-octreotide (OCT) scan or 68Ga DOTA-TATE PET/CT can detect the disease.X-ray,CT and MRI can identify the lesions.The lesions of femoral head were basically under the joint surface,with a nodular change.Part of the tumor was infiltrating and close to the cortex.The pathology was mainly manifested as a large number of thin-walled vessels in the bone trabeculae.There were dense spindle cells or astrocytes between the blood vessels and the atypia is not obvious.Three patients were treated with total hip arthroplasty and two with segmental resection and bone graft.After surgical removal of the tumor,the patient's systemic pain or anemic symptoms were gradually relieved and the joint function was restored.Meanwhile,the bone density was increased.Conclusion The clinical features of the phosphaturic mesenchymal tumors in hips were not obvious.Comprehensive diagnosis should be carried out in combination with the clinical manifestations,laboratory examination,radiological examination and pathological examination.Total hip arthroplasty or segmental resection with bone graft can effectively remove the tumor and achieve good prognosis.

Objective To investigate the effects of different early enteral nutrient (EN) emulsions of TPF-T and TP on nutritional status and intestinal mucosal barrier in patients with septic shock. Methods From May 2017 to May 2018, 112 patients with septic shock were continuously enrolled in the Department of Intensive Care Unit of the First People's Hospital of Taizhou, and they were randomly divided into a TPF-T group and TP group, each group with 56 cases. After admission, the patients in both groups were all treated according to the 2016 Saving Sepsis Campaign (SSC) Guidelines for septic shock. Both groups were supported with EN, TPT-T group was given TPF-T EN emulsion rich in fish oil, while TP group was supported with standard TP EN emulsion, and the therapeutic course was consecutive 7 days in both groups. The differences in nutritional status, inflammatory response, immune function, intestinal mucosal barrier, gastrointestinal symptoms and prognosis were compared between the two groups. Results After EN, the nutrition indicators such as albumin (Alb), prealbumin (PA), transferrin (TRF) and immune indexes (IgA, IgG), human leukocyte DR antigens (HLA-DR) and D-lactic acid were increased in both groups, reaching the peaks on the 7th day after EN application, Alb, PA, TRF, IgA, IgG, HLA-DR in the TPF-T group were significantly higher than those in the TP group [Alb (g/L): 34.43±5.81 vs. 33.59±5.34, PA (mg/L): 269.83±47.56 vs. 252.67±41.92, TRF (g/L): 3.43±0.64 vs. 3.32±0.81, IgA (mg/L): 159.45±34.56 vs. 143.31±33.81, IgG (mg/L): 4 947.68±871.66 vs. 4 583.75±841.54, HLA-DR: (68.22±9.11)% vs. (62.21±9.69)%], and after EN, the D-lactic acid in the TPF-T group was significantly lower than that in the TP group (mg/L: 30.42±6.79 vs. 33.34±7.31). The inflammatory indicators of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), procalcitonin (PCT), endotoxin and diamine oxidase (DAO) were all gradually reduced in two groups, reached the lowest levels on the 7th day after EN application, and all the above-mentioned indicators in the TPF-T group were significantly lower than those in the TP group [TNF-α (ng/L):95.43±20.69 vs. 109.59±23.45, CRP (mg/L): 21.33±16.35 vs. 32.36±17.83, PCT (μg/L): 1.24±1.21 vs. 4.18±1.32, endotoxin (U/L): 10.32±2.31 vs. 11.54±2.69, DAO (g/L): 19.45±8.49 vs. 25.47±9.41]. The incidences of gastric retention, diarrhea and paralysis of lower digestive tract in TPF-T group were significantly lower than those in TP group [gastric retention: 14.29% (8/56) vs. 32.14% (18/56), diarrhea: 12.50% (7/56) vs. 35.71% (20/56), paralysis of lower digestive tract: 7.14% (4/56) vs. 23.21% (13/56)], the length of hospital stay was significantly shorter in the TPF-T group than that in the TP group (days: 18.77±5.08 vs. 21.71±6.67, P < 0.05); however, there was no significant difference in mortality between the two groups [14.29% (8/56) vs. 21.43% (12/56), P > 0.05]. Conclusion TPF-T could more effectively maintain nutritional status, reduce inflammatory reaction, improve immunity, protect intestinal mucosal barrier function, and has fewer adverse reactions, which was helpful to improve the prognosis of septic shock patients.

Objective: To understand the prevalence and disease burden of major chronic diseases in the elderly in China and provide scientific basis for the prevention and control of chronic diseases and for the rational allocation of health resources. Methods: We analyzed the prevalence of chronic diseases in residents aged ≥60 years in China by using national and provincial surveillance data of chronic diseases and related risk factors in China. We conducted the analysis on the burden of chronic diseases in the elderly in China by using the data of global burden of disease. Results: The prevalence rates of hypertension, diabetes and hypercholesterolemia were 58.3%, 19.4% and 10.5% respectively in residents aged ≥60 years in China. Up to 75.8% of the residents aged ≥60 years had at least one chronic disease. The prevalence rate was higher in women than in men, higher in urban area than in rural area. With the increase of age, the prevalence rate of chronic diseases also increased. The top three chronic diseases with heavy disease burden in residents aged ≥70 years were stroke, myocardial infarction, cancer and chronic obstructive pulmonary disease. Conclusion The prevalence of major chronic diseases in the elderly is high with three quarters of the elderly suffering from at least one chronic disease, and the burden of chronic diseases is increasing.
