Objective To compare the long-term outcome between breast-conserving therapy with mastectomy therapy for early stage invasive breast cancer through a Meta analysis of the randomized controlled trials published worldwide.Methods Cochrane systematic evaluation was used to search through Cochrane libraries of clinical comparative trials,PubMed,Embase,Cancer Lit,and so on.The quality of literatures was independently evaluated and cross-checked by two evaluators,indicators for assessment including death number at the end of follow-up,locoregional and total recurrence.The results were analyzed with RevMan 4.2.2 software.Results Six articles were involved in the Meta analysis with total 3 933 patients.No statistical difference was found in the death at the end of follow-up between breast-conserving therapy group and mastectomy therapy group(OR=1.05,95% CI=0.93-1.19,P=0.45).Locoregional and total recurrence rate of breast-conserving therapy group were statistical higher than those in mastectomy therapy group(OR=1.64,95% CI:1.10-2.44,P=0.01;OR=1.42,95% CI:1.22-1.64,P

Objective To evaluate the relationship between classification of clinical,the infarct size in patients with acute cerebral infarction and electrocardiographic(ECG)changes.Methods The ECG were done in 216 patients with acute cerebral infarction.ECG results of the patients were analyzed according to classification of the Oxfordshire Commumity Project Criteria(OCSP)and infarct size.Results The rates of ECG abnormality in classification of OCSP were 95.5% for total anterior circulation infarction(TACI),80.4% for partial anterior circulation infarction(PACI),62.5% for posterior circulation infarction(POCI)and 48.5% for lacunar cerebral infarction(LACI).The rates of ECG abnormality of TACI and PACI were signficantly higher than that of group of LACI(P

Objective To investigate the incidence and risk factors of postcholecystectomy syndrome (PCS), and provide theoretical basis for the prevention of PCS. Methods A total of 338 patients with PCS were randomly selected in our hospital from May 1st 2013 to April 30th 2014, in which 316 cases were successful followed up including 101 males and 215 females. The data were collected from the 7 aspects including blood type, drinking history, smoking history, diabetes history, mental anxiety, dietary tendence and preoperative symptoms, and which were analyzed by binary-logistic regression analysis. Results According to the PCS diagnostic criteria, 115 patients were diagnosed with PCS (36.39%). The anxiety status and preoperative discomfort were closely related to the occurrence of PCS, with statistically significant difference (P<0.05). Conclusion The diagnosis and treatment of PCS are more complicated. We should focus on the prevention of PCS according to its risk factors, and pay attention to preoperative communication and individualized analysis of patients in order to reduce the occurrence of PCS.

Objective To validate the accuracy of the revised Atlanta classification (RAC) and the determinant-based classification (DBC) for severity of acute pancreatitis.Methods We retrospectively analysed the clinical data from 192 patients with acute pancreatitis who were admitted to our hospital between January 2014 and October 2014.Using the RAC and the DBC,The duration of total parenteral nutrition,length of ICU and hospital stay,operation rate and mortality were assessed in the subgroups,respectively.Results Fluid collections in and around the pancreas was present in 74 patients (38.5％),pancreatic or peripancreatic necrosis in 51 (26.6％),and infection in 18 (9.4％).On the basis of the RAC,106 patients (55.2％),77 patients (40.1％),and 9 patients (4.7％) were classified to have mild,moderately severe,or severe AP,respectively.On the basis of the DBC,11l (57.8％),62 (32.3％),14 (7.3％),and 5 (2.6％) patients were classified to have mild,moderate,severe,or critical AP,respectively.The different categories of severity for each classification system were significantly associated with the duration of total parenteral nutrition,the length of ICU and hospital stay,the operation rate and mortality.Conclusion Both the RAC and DBC accurately classified the severity of AP and differentiated prognosis in the subgroups of patients.

Infected pancreatic necrosis (IPN) is a serious complication which may cause organ failure and death in patients with acute pancreatitis. Surgical debridement is an important therapeutic approach for IPN. With the development of evidence-based medicine, more and more high-level evidences emerge for surgical debridement of pancreatic necrosis tissue, and the traditional treatment strategy has also changed. In the era of minimally invasive surgery, whether 'delayed surgery' should still be executed and how to achieve 'delayed surgery' are the research hotspots in the treatment of IPN. Research evidences reveal that the 'step-up' strategy is not the best strategy for all IPN patients, and alternatives should be explored. In addition, the indications, advantages and disadvantages of open surgery, surgical minimally invasive surgery and endoscopic surgical debridement of pancreatic necrosis tissue have been widely discussed in recent years, and no consensus has yet been reached. At present, the personalized, multidisciplinary, and minimally invasive treatment of IPN is still the mainstream development direction. The authors investigate the timing and strategy of surgical treatment for IPN in order to provide theoretical basis for clinical practice.

Objective To determine the effect of video-assisted retroperitoneal debridement in treatment of infected necrotizing pancreatitis.Methods The clinical data of patients with infected necrotizing pancreatitis was retrospectively analyzed.Heart rate,mean arterial pressure,body temperature and indicators for inflammatory response including level of WBC,CRP and procalcitonin before and after VARD treatment were compared.Results After VARD treatment,the heart rate (preoperative vs.postoperative 8 h,108 ± 22/min vs.95 ± 17/min),mean arterial pressure (preoperative vs.postoperative 12 h,66 ± 18 mmHg vs.79 ± 19 mmHg) and body temperature(preoperative vs.postoperative 24 h,38.3 ± 1.7 ℃ vs.37.3 ± 1.3 ℃) improved significantly (all P ＜ 0.05).Level of WBC [preoperative vs.postoperative 48 h,(13.8 ±6.6) × 109/L vs.(10.1 ±5.2) × 109/L],CRP(preoperative vs.postoperative 48 h,145 ± 88 mg/L vs.95 ± 4 mg/L) and procalcitonin (preoperative vs.postoperative 48 h,1.4 ± 0.7 μg/L vs.0.9 ± 0.4 μg/L) also decreased significantly(all P ＜ 0.05).Conclusions VARD therapy can significantly reduce systemic inflammation and improve the general condition of infected necrotizing pancreatitis patients.

Objective To evaluate the MRI and clinic types of oxfordshire community stroke project(OCSP)in the diagnosis of acute young ischemic stroke patients.Methods 1 64 young patients (18-45 years)and 228 old patients (>60 years)with acute ischemic stroke were analyzed retrospectively.There are four groups according to MR and clinic types of OCSP:total anterior circulation infarct (TACI),partial anterior circulation infarction (PACI),posterior circulation infarction(POCI)and lacunar infarction (LACI).Results Cerebral infarction showed a mild hypo-signal on T1 WI,hyper-signal on T2 WI,FLAIR and DWI.Among the 164 young patients,8 (4.88%)were classified as TACI,72 (43.90%)as PACI,30 (18.29%)as POCI and 54 (32.93%)as LACI.Young and old group image types comparison,χ2 = 1.221,P >0.05.Young stroke patients image and clinical types comparison,Kappa =0.525,P <0.05.Conclusion OCSP imaging types has a good consistency with clinical types,which helps to evaluate ischemic stroke objectively in youth.

Objective:To observe the clinical efficacy of warm needling moxibustion plus tuina in treating knee osteoarthritis (KOA) due to cold-dampness blocking collaterals.
Methods:Forty-eight KOA patients were randomized into 2 groups by their visiting sequence, 24 cases in each group. The treatment group was intervened by warm needling moxibustion plus tuina, while the control group was treated with acupuncture plus tuina. The two groups were both treated once a day, 30 min for each session, 10 d as a treatment course, totally for 3 treatment courses. The visual analogue scale (VAS) and Lysholm knee scoring scale (LKSS) were observed before and after the treatment to evaluate the clinical efficacy.
Results:After 3 treatment courses, the VAS and LKSS scores were significantly changed in the two groups (P<0.01), and the between-group differences were also statistically significant (P<0.01). The markedly-effective rate was 83.3% in the treatment group versus 66.7% in the control group, and the difference was statistically significant (P<0.05).
Conclusion:Warm needling moxibustion plus tuina can produce a more significant efficacy than acupuncture plus tuina in treating KOA due to cold-dampness blocking collaterals.
