Objective　The authors present a retrospective analysis of 22 patients with primary central nervous system lymphoma(PCNSL) in order to provide a reasonable basis for the diagnosis and treatment of the disease. Methods　This report involves a clinicopathological study of 22 patients with histologically proven PCNSL,all diagnosed between January 1993 and May 2000. Univariate and multivariate regression analysis are used to determine prognostic factors significantly associated with an unfavorable or favorable impact on survival. Results　The cohort included 11 men and 11 women whose median age at diagnosis was 49.5 years. At the end point of follow-up, 11 died. The median survival time for the patients in study was 14.5 months. With univariate and multivariate regression analysis, prognostic factors significantly associated with survival included intrathecal injection(P=0.005) and local/diffuse neurological deficit(P=0.031). Conclusion　There continues to be a significantly increasing incidence of PCNSL. This survey throws light on the clinical and prognostic features of this uncommon disease. Through univariate and multivariate regression analysis the authors highly recommend a theraputic regime including surgery, intrathecal injection and chemotherapy, especially those drugs capable of passing blood-brain barrier, for example high dose MTX.

This paper aims to investigate the value of diffusiion weighted imaging (DWI) and different apparent diffusion coefficient (ADC) methods to predict the curative effects of neoadjuvant chempotherapy (NAC) for breast cancer. From March 2010 to December 2012, seventy-one patients were pathologically confirmed invasive breast cancer by needle puncture biopsy received before surgery, and underwent magnetic resonance before and after NAC, the ADC were measured by mean ADC method and lower ADC method. The pathologic response after NAC was divided to major histological response (MHR) group and non-major histological response (NMHR) group according to Miller & Payne system. Results displayed that ADC values obtained before NAC, at the end of the second cycle of NAC, and after whole course of treatment, had good correlations between mean and lower ADC methods (the Pearson's correlation=0.699, 0.749 and 0.895, respectively). Significant difference in ADC obtained both with mean and lower ADC methods could be found between MHR and NMHR groups after the second cycle of NAC (P< 0.05). After the second cycle of NAC, significant difference in the change rate of ADC could be found between MHR and NMHR groups by using lower ADC method (P<0.05), but not be found by using mean ADC method (P >0.05). In conclusion, DWI could monitor the pathologic changes of breast cancer after NAC, and the lower ADC method might be used to evaluate the curative effect of NAC with the change rate of ADC.

Objective To identify a rapid and efficient fungal genomic DNA extraction method for PCR amplification.Methods Genomic DNA was extracted from Penicillum marneffei,Rhizopus microsporus,Cryptococcus neoformans and Candida albicans by heating pyrolysis,microwave,repeated freezing and thawing,lysozyme digestion,overnight snail enzymatic and Qiagen kit methods.DNA electrophoretogram was observed by gel imaging system.The concentration and purity of extracted DNA were determined with an ultramicro nucleic acid protein tester and the yields were calculated.PCR amplification and sequencing were also performed.ANOVA and SNK-q test were used for data analysis.Results There were statistical differences in concentrations and yields of the fungal DNA extracted from Penicillum marneffei (hyphal phase and yeast phase),Rhizopus microsporus,Coptococcus neoformans and Candida albicans by six methods (F=750.83,220.95,669.35,132.01,510.20 and 1658.35,287.10,963.64,1147.77,4521.22,all P ＜0.01).Of six methods,microwave method gained the highest DNA concentration and yield,followed by heating pyrolysis method,while Qiagen kit method obtained the lowest concentration and yield.All DNA extracted by 6 kinds of methods were positive in PCR amplification.Conclusion All of the six methods can be used for fungal DNA extraction which is sufficient for PCR amplification,but microwave and heating pyrolysis methods are more easy and simple to perform.

Objective To explore surgical methods of removing polyacrylamide hydrogel (PAHG) and the right time of repairing the deformity of breast after removing PAHG.Methods We operated with endoscopy to remove PAHG through the lower mammary areolar incision.According to injection influence,we made the dicision whether to put the silicon gel prosthesis (hereafter referred to as prosthesis) simultaneously,and to fix the porsthesis,and to rebuild the imframammary fold of breast using biological repair membrane (hereafter referred to as membrane).Results In all 46 patients,39 patients' injection and their envelope were removed entirely.7 patients left part of the envelope because of its thin and wide characters.14 of them accepted prosthesis augmentation mammaplasty simultaneously and 5 of these accepted membrane repair.4 patients received prosthesis augmentation in stage Ⅱ.All patients' incision were primary healing.The incision scars were not obvious.1 patient with breast cancer suffered breast excision; 1 patient who received prosthesis and membrane simultaneously appeared prosthesis displacement after 3 months and fixed again.1 patient who received membrane appeared hydrops in residual cavity,and the membrane was removed finally.Conclusions This method with endoscopy through mammary areolae is necessary for cleaning PAHG entirely.We can use prosthesis to repair the deformity of breast after removing PAHG,and if necessary use membrane to fix the implant and rebuild the inframammary fold of the breast.

Objective To evaluate the intraoperative opioid?sparing effect of different duration transcutaneous electrical acupoint stimulation ( TEAS ) in video?assisted thoracoscopic lobectomy. Methods Seventy?five patients, aged 18-64 yr, weighing 40-96 kg, of ASA physical status Ⅰ or Ⅱ, scheduled for elective video?assisted thoracoscopic lobectomy under general anesthesia, were randomly divided into 3 groups (n=25 each) using a random number table: control group (group C), 30 min of stimulation before induction of anesthesia group ( group B) , and stimulation throughout surgery ( group T) . In group B, the patients received TEAS ( frequency 2∕100 Hz ) on acupoints Xinshu ( BL15 ) , Feishu (BL13), Neiguan (PC6), Hegu (LI4) on the operated side starting from 30 min before induction of anesthesia until the beginning of induction, and the intensity was the maximum current that could be tolerated. The intensity for Neiguan ( PC6) and Hegu ( LI4) was 6-12 mA, and for Xinshu ( BL15) and Feishu ( BL13 ) was 9-18 mA. In group T, the patients received TEAS on the four acupoints mentioned above starting from 30 min before induction of anesthesia until the end of surgery. The patients had the electrodes applied, but received no stimulation in group C. After anesthesia was induced with propofol?sufentanil?cisatracurium, double lumen endotracheal tube was inserted. Propofol was given by target?controlled infusion to maintain BIS value within the range of 40-60. Cisatracurium was infused continuously to facilitate muscle relaxation. The infusion rate of remifentanil was adjusted to maintain analgesia nociception index value within the range of 50-70. The intraoperative consumption of remifentanil ( the intraoperative consumption of sufentanil was converted to the consumption of remifentanil producing the equivalent effect by 1∶ 10) was recorded. Results Compared with group C, the intraoperative consumption of remifentanil was significantly decreased in B and T groups. The intraoperative consumption of remifentanil was significantly lower in group T than in group B. Conclusion TEAS on Xinshu ( BL15 ) , Feishu (BL13), Neiguan ( PC6) and Hegu acupoints throughout surgery and for 30 min before induction of anesthesia significantly reduces intraoperative opioid consumption in the patients undergoing video?assisted thoracoscopic lobectomy, while TEAS throughout surgery provides better effect.
