A 54-year-old female presented with indurated nodules and plaques on the left chest and back for 32 years.Skin examination showed little finger- to soybean-sized,slightly whitish indurated nodules with little mobility arising on skin-colored indurated plaques following Blaschko's lines on the left chest and back.The lesional skin was sclerotic and atrophic,and the lesions were distributed unilaterally.Serum levels of calcium,phosphate,alkaline phosphatase and parathyroid hormone were normal.Histopathological examination revealed fibrous scar with flake-like calcification.The diagnosis was idiopathic calcinosis cutis following Blaschko's lines.

Objective:To investigate the relationship between EGFR mutations and pulmonary tuberculosis in lung adenocarcino-ma. Methods:We detected EGFR mutations in 506 patients with lung adenocarcinoma by PCR amplification and sequencing and ana-lyzed the relationship between the mutations observed and pulmonary tuberculosis. Survival analysis was performed using the Ka-plan-Meier method with log-rank tests. Result:A total of 218 patients showed EGFR mutations;of these patients, 25 had a clinical his-tory of pulmonary tuberculosis. Compared with lung adenocarcinoma patients with no history of tuberculosis, patients with a history of pulmonary tuberculosis showed higher incidence rates of EGFR mutations, especially of exon 21 (P=0.047, P=0.002). Higher incidence rates of EGFR mutations, especially of exon 21, were observed in patients with lung cancer and tuberculosis in the same lobe or the same side of the lung than in those who had lung cancer and tuberculosis in opposite sides of the lung (P=0.02, P=0.03). Survival analy-sis showed that adenocarcinoma patients with a history of pulmonary tuberculosis have 2-year survival rates lower than that of adeno-carcinoma patients with no history of the disease (P=0.039). In patients adenocarcinoma associated with tuberculosis patients without EGFR-TKIs treatment, the 2-year survival rates of EGFR mutation patients and those without EGFR mutation showed no statistically significant difference (P=0.948). At the same time, we got the same results in adenocarcinoma associated with tuberculosis patients with EGFR-TKIs treatment (P=0.425). Conclusion:Lung adenocarcinoma patients with a history of pulmonary tuberculosis have high-er incidence rates of EGFR mutations, and EGFR mutations are not related to disease prognosis.

Objective To investigate the effects on brain tissue p38 mitogen-activated protein kinase (MAPK) and aquaporin 4 (AQP4) and neuroprotective effect of edarvone after focal cerebral ischemia and reperfusion in mice.Methods A total of 196 healthy male Kunming mice were randomly divided into four groups:a sham operation group,an ischemia-reperfusion group,a saline control group,and an edaravone group (n =49 in each group).A middle cerebral artery occlusion (MCAO) mothod was used to induce a cerebral ischemia-reperfusion model.At 2 h after ischemia,immediately after reperfusion in the edaravone group and the saline control group,edaravone (5 mg/kg) and the same volume of saline were injected intraperitoneally in mice,then repeated once every 24 h.At 2 h after MCAO,the brain water content and infarct volume at different time points after reperfusion (12 h,24 h,48 h,and 3 d) were measured respectively.At 24 h after MCAO,the expressions of AQP4 and p38 MAPK in the brain tissue of ischemic peripheral cortex were measured by Western blotting.Results The volumes of cerebral infarction (all P ＜ 0.01) and the brain water contents (all P ＜0.05) in the edaravone group were decreased than those in the ischemia-reperfusion group and saline control group at different time points,and they were most significant at 48 h.After 24-h reperfusion,the expression levels of AQP4 (0.985 ± 0.129,1.024 ± 0.117,0.713 ± 0.231) and phospho-p38 MAPK (1.123 ± 0.142,1.214 ± 0.096,0.986 ± 0.087) in the brain tissue of ischemic peripheral cortex in the ischemia-reperfusion group,the saline control group,and the edaravone group were upregulated significantly than those in the sham operation group (AQP4:0.265 ± 0.123;phospho-p38 MAPK:0.465 ±0.023;all P ＜0.01),but edaravone group were significantly lower than the ischemia-reperfusion group and the saline control group (all P ＜ 0.05).Conclusions Edaravone can downregulate the expression level of AQP4 and effectively protect cerebral ischemia reperfusion injury in mice,Its mechanism may be associated with the inhibition of p38 MAPK pathway.

Objective To assess the effect of family doctor team care on morbidity of disabled elderly in home care.Methods Eighty six disabled elderly patients with home care in Shanghai Xujiahui community were enrolled from February 2014 to January 2015.The patients were randomly divided into intervention group and control group with 43 cases in each.In intervention group,the family doctor team provided long-term,comprehensive and integrated care,and in control group the conventional home care was provided.The rates of morbidity and readmission to hospital were documented during the 3,6 and 12 monthfollow-up,and compared between two groups.Results The incidence rates of bedsore,pneumonia and deep vein thrombosis in intervention group was significantly lower than those in control group [after 6 months:4.9％ (2/41) vs.28.9％(11/38),x2 =8.311;2.4％ (1/41) vs.21.1％ (8/38),x2 =6.769;2.4％ (1/41) vs.15.8％ (6/38),x2 =4.353,respectively;after 12 months:2.4％ (1/41) vs.42.1％ (16/38),x2 =18.374;4.9％ (2/41)vs.28.9％ (11/38),x2 =8.311;7.3％ (3/41)vs.28.9％ (11/38),x2 =6.328,respectively;all P ＜0.05].The number of cases with bedsore healing(6/7 vs.0,x2 =18.555)and pneumonia recovery[5/6 vs.4.3％ (1/23),x2 =18.092] was significantly more and that with pneumonia deterioration (0 vs.52.2％ (12/23),x2 =5.340)was significantly less in intervention group than those in control group (all P ＜ 0.05).More cases with deep vein thrombosis improved(1/3 vs.0,x2 =3.949) and less cases with deep vein thrombosis deteriorated(0 vs.8/11,x2 =5.091) in intervention group than those in control group (P ＜ 0.05).And both the readmission rate for home care patients [2.4％ (1/41) vs.36.8％ (14/38),x2 =15.175] and for patients with complications [1/12 vs.43.8％ (14/38),x2 =4.872] was much lower in intervention group than that in control group (both P ＜ 0.05).Conclusion The family doctor team care can reduce the risk of complications and readmission to hospital,and also can improve the quality of life of home care disabled elderly,as well as reduce the burden of family and society.

Objective To investigate the expressions of indoleamine 2,3-dioxygenase (IDO) and transcription factor forkhead box P3(FOXP3)in gallbladder adenocarcinoma; and to evaluate the relationship between the expressions of IDO and FOXP3 protein,and clinicopathology and lymph node metastasis of gallbladder carcinoma.Methods The expressions of IDO and FOXP3 in 51 cases of primary gallbladder cancer,90 cases of chronic cholecystitis,and 20 cases of normal gallbladder tissues were studied by immunohistochemical staining. Results The positive expression rates of IDO and FOXP3 in gallbladder carcinoma were 72.5％ (37/51) and 60.8％ (31/51),in normal gallbladder mucosa were 5％ (1/20) and 20.0％ (4/20),in cholecystitis and gallstone were 11.1％ (10/90) and 32.2％ (29/90),respectively.There were significant differences among the three groups in IDO and FOXP3 expressions (P＜0.01).The positive expression rates of IDO and FOXP3 were 7.1％ and 14.3％ for simple hyperplasia,17.7％ and 35.3％ for atypical hyperplasia,40％ and 35％ for gallbladder carcinoma (stages Ⅰ-Ⅲ),and 77.4％ and 64.5％ for gallbladder carcinoma (stages Ⅳ-Ⅴ ).There were significant differences among the four groups in IDO and FOXP3 expressions (P＜0.01).There were significant differences among the Nevin stage groups,lymph node metastasis group and gallbladder stone in IDO and FOXP3 expressions.However,there were no significant differences among the sex groups and the age groups in IDO and FOXP3 expressions (P＞0.05).In gallbladder carcinoma,the expression of IDO had a positive correlation with FOXP3 expression in lymphocyte (γ=0.406,P=0.003).Conclusion In gallbladder cancer,a high-expression of IDO and an expression of FOXP3 in lymphocyte are closely related with immune tolerance of gallbladder carcinoma.The results provide a reference for clinical use of immunotherapy in gallbladder cancer.

Pancreatic cancer is a highly malignant neoplasm with dismal prognosis. The risk of recurrence and metastasis remains high even for patients who have undergone radical dissection. Therefore, adjuvant therapy after "curative" resection is crucial. However, consensus on the optimal management of pancreatic cancer after surgery has not been reached. Both chemotherapy and concurrent chemoradiation therapy have been advocated. Yet, based upon the results of published phase Ⅲ trials, the consensus and standard strategy of adjuvant treatment after pancreatic cancer surgery is still undo" debate. According to the results of GITSG and RTOG trials, the mainstream in North American is adjuvant chemoradiation. However, based on the results of ESPAC-1 and CONKO-001 studies, the oncologists in Europe usually recommend chemotherapy alone. Furthermore, the superiority of gemcitabine over 5-FU in the adjuvant setting is largely unclear. This article reviewed the main results of the clinical trials in the field of adjuvant treatment of pancreatic cancer.From the authors' view, both the standard dosage of gemcitabine (CONCO-001) and chemoradiation (RTOG-9704) after resection of pancreatic cancer could be considered as candidates for adjuvant strategy. However, the optimal therapy will have to be determined by trials with larger number of patients.
