Asthenia in origin and asthenia in superficiality is the pathogenesis of dermatomyositis,deficiency of yang qi is the interior etiopathogenisis and the invasion of exogenous evil is the exterior etiopathogenisis.The treatment principles of dermatomyositis are strengthening healthy qi to eliminate pathogens and treating both manifestation and root cause of disease.The course includes acute stage,paracmasis and recovery stage.Based on syndrome differentiation,different treatment principles are used in clinic and achieve significant therapeutic effect.

With the development of the main tumor gene sequencing projects,driver mutations have been put into the highlight due to its significant meaning on the cancer occurrence,development as well as treatment.In the past decade,based on the finding of new driver mutations,the knowledge of non-small cell lung cancer (NSCLC) have been improved from the traditional pathological classification to the current molecular classification.Meanwhile,NSCLC patients are no longer looked as an assembly of the same type tumor but various individuals with different molecular biology behavior with the different sensitivity to the targeted drugs.This article focuses on the recent discovery advances of driver mutations in lung adenocarcinoma.

AIM: To investigate the effects of different phacoemulsification incision for tear film stability in cataract patients.
METHODS: From January 2014 to September 2015, 108 patients (144 eyes) who underwent cataract surgery were divided into two groups: group A with clear corneal incision ( 52 cases with 74 eyes), group B with scleral tunnel incision (56 cases with 70 eye). Two groups of patients were taken the same incision width. Symptoms of dry eye and tear film break - up time ( BUT) were observed 1d before and 1d, 1, 3wk, 1 and 3mo postoperatively.
RESULTS:After performing cataract phacoemulsification 1d, 1wk, symptoms score of dry eye of group A was less than that of group B, the difference was statistically significant (t = -6. 199, -2. 871, P<0. 01), while at other times after operation there were no significant differences ( t = - 1. 639, - 0. 829, - 0. 301, P >0. 05); at postoperative 1d, 1 and 3wk, BUT of group B was better than those of group A, there were a statistically significant differences ( t = - 3. 718, -2. 342,-2. 506, P<0. 05), there were no significant differences at other the time after operation (t= -0. 882,1. 225, P>0. 05).CONCLUSION: The difference on effect of two different incision on the tear film stability only last a short time, which disappeared at 1mo after operation. The clear corneal incision has stronger impacts on tear film stability than scleral tunnel incision, while with a lower score on symptoms of dry eye.

Autoimmune hemolytic anemia is a disorder of immune function caused by various reasons, by produceing autoantibody or complement which can react with erythrocyte autoantigen, increasing the destruction of red blood cell and beyond the compensatory ability of bone marrow hematopoiesis.Children usually have acute onset and the clinical manifestations are related to the pathogenesis.As the first-line treatment of glucocorticoids, Most children respond well to glucocorticoids.Some children suffer from steroid dependence and resistance; or recurrence due to different types of antibodies, often requiring second-line treatment, such as splenectomy, immunosuppressive, etc.This article reviews the recent progress in the treatment of children with autoimmune hemolytic anemia.

Objective To investigate the characteristic, diagnosis and treatment of occult breast carcinoma(OBC). Methods The clinical data of 12 cases of OBC were analyzed retrospectively.Results All patients showed axillary node enlargement as the first sign and were operated on. The operation included axillary node excision (ANE) in 1 patient, axillary node excision plus simple mastectomy in another one, radical mastectomy in 6, and modified radical mastectomy in the other 4,respectively. Eleven patients (91.7%) were followed up for 1-15 years. During the follow up, 1 patient who underwent axillary node resection and 1 who received ANE plus simple mastectomy died of systemic metastasis,18 and 22 months after operation respectively;another case who subjected to radical mastectomy had axillary lymph node metastasis 3 years after the operation,and was re operated on,but the patient died of lung metastasis 4 years after the reoperation. And the others still survived, in which 2 have lived for over 3 years, 2 over 5 years, and 4 over 10 years. Conclusions For axillary mass which causes are uncertain, the possibility of OBC should be considered.Meanwhile excision and pathological examination are necessary. The metastatic histological structure of the axillary nodes usually provide important clue for the source of tumor. Radical or modified mastectomy is the best treatment,and post operative chemotherapy and/or radiotherapy should be done.

Objective To study the diagnosis of chronic lymphocytic thyroiditis (CLT), and the treatment of CLT companied with other thyroid diseases. Methods Clinical data of 63 cases of CLT were analyzed retrospectively. Results 26 cases were diagnosed by non-operative methods (11 cases by fine needle aspiration biopsy, FNAB). The rest of 37 cases were operated on because of misdiagnosis as other thyroid disease and then comfirmed as CLT by pathology. Of them, 2 were companied with nodular goiter, 6 with Graves' disease, 1 with thyroid adenoma and 2 with carcinoma, respectively. 19 cases were treated by thyroixine, 3 were not treated, 4 treated by operation after thyioxine managment and 37 were treated by operation. Non-operation group had rather satisfied effect in short-term period. 29 cases (78.4%) in operation group were followed up for 1 to 6 years, and 5 cases had hypothyroidism. Conclusions It is necessary to have complete serum immunologic examination and FNAB for suspect patients.They have to be examined carefully in order to avoid omitting complications and incsease the rate of diagnosis.Non-operative treatment is the major therapy of CLT. If CLT is companied with other thyroid disease, operation or non- operation should be adopted according to the pathological type.

Objective To study the mechanism of rat blood pressure lowered by SO2 and SO2 derivatives.Methods 6-Keto-PGF1? and TXB2 were determined by radioimmunoassay in the plasma and aorta tissue of rats.Results The 6-Keto increased significantly in the isolated aortic rings in all exposure groups except 8 mmol/L group.No change of TXB2 was observed in the rings in all exposure groups.Meanwhile,6-Keto/TXB2 ratios increased significantly at 2 mmol/L and 4 mmol/L.Compared with the control group,6-Keto level decreased significantly in the plasma of the rats exposed to SO2 at 14 mg/m3,28mg/m3 and 56 mg/m3,but the level of TXB2 increased significantly.6-Keto/TXB2 ratios decreased gradually with the increase of SO2 concentration.Conclusion PGI2 and TXA2 are possibly changed by SO2 and SO2 derivatives,which regulates partly rat blood pressure.

Purpose:To investigate the clinical characteristics, diagnosis and treatment of accessory breast tumors.Methods:Clinical and pathological data of 16 cases of accessory breast tumors were analyzed retrospectively. Results:There were 5 cases of accessory breast fibroadenoma, 2 cases of intraductal papilloma, 9 cases of accessory breast carcinoma. Local mass resection and radical resection were carried out respectively. All these patients had post operative chemotherapy and radiotherapy. 13 cases (81.3%0 were followed up for 1—10 year. As to results, 3 cases died of metastasis in 2,2.5 and 4 years respectively after operation;one case, reoperated because of local recurrence, still survives (over 3 years):and the others recovered well.Conclusions:It is possible for benign or malignant tumor to occur in the accessory breast,and the manifestation of the accessory breast tumors is similar to that of the primary breast tumor. Operation is the first choice for all treatment benign tumor with local mass resection including the whole accessory breast while accessory breast carcinoma should be treated by radical dissection.

Purpose: To investigate the diagnosis, pathological characteristics and treatment of primary malignant lymphoma of the breast (PMLB). Methods: Clinical and pathological data of 16 cases of PMLB were analyzed retrospectively. Results: No case was correctly diagnosed before operation. All the 12 cases were operated and identified by pathology, in which total mastectomy, radical mastectomy and modified radical mastectomy were carried out in 5, 3 and 4 patients respectively. Moreover, all cases were combined with post-operative chemotherapy or radiotherapy. 10 cases were followed up 1 - 10 years. 4 cases who survived 22 months on the average died of the tumor spread and metastasis during follows-up, and the others are still alive. Especially, 1 case, recurring 2 times locally, has survived for 4. 5 years after reoperation. Conclusions: The final diagnosis of this disease depends on the pathological examination. The majority of PMLB is non-Hodgkins lymphoma ( NHL), and mostly of B cell origin and are mostly related to the mucosa-associated lymphoid tissue ( MALT). Total mastectomy or mastectomy plus axillary nodes dissection is the preferred method of operation and the adequate post-operative chemotherapy is very important.

Objective To compare the effect of different general anesthesia method on preoperation cognitive function in elderly patients.Methods According to the digital table,82 elderly patients(non cardiac surgical operation) were selected and divided into the two groups,each group 41 cases.The group A was given to sufentanil combined with propofol intravenous injection anesthesia,and the group B was given to sevoflurane inhalation anesthesia.The cognitive function of patients of two groups in preoperative,postoperative 3h,6h,24h were assessed by simple intelligence scale(MMSE),and the indicators of postoperative recovery were evaluated.Results The postoperative sleep time [(6.9 ± 1.2) min],language ability recovery time [(9.8 ± 2.2) min] in the group A were all higher than those of group B (t =6.687,5.640,all P ＜ 0.01).The MMSE scores in group A after 3h [(17.1 ± 2.2) points],6h [(19.6 ±2.7)points],24h[(22.4 ±2.3) points] were lower than those of group B(t =10.026,6.229,5.082,all P＜0.01).And the PCOD rate in group A after 24h was 36.6％,which was higher than 17.1％ in group B(x2 =3.98,P ＜ 0.05).Conclusion The inhalational anesthetic methods has more quickly postoperative recovery,lower incidence of cognitive dysfunction,better clinical effects.
