Surgical approaches for esophageal carcinoma are many and varied. Minimally invasive techniques are increasingly used widely in esophagectomy as they not only ensure patients' therapeutic effects, but also reduce trauma and accelerate recovery. The lymph nodes excisional area of esophageal carcinoma is still in controversy. It is necessary to carry out further researches on selective lymph nodes excision, which can decrease complication rate and improve patients' survival in the meantime.

Objective To explore the clinical features of pulmonary tuberculosis complicated with DM and related factors. Method The manifestations of 87 newly diagnosed PTB patients with type 2 DM(DM-PTB group) at two hospitals in Tianjin during October 2003 to October 2004 were compared to 88 PTB patients without DM who were randomly choosen from the same hosipital.The factors related to sputum-positive TB or cavity were explored through unconditional logistic regression model. Results DM-PTB patients showed significanly lower frequencies of cough(66.7% vs 83.0%),toxicity symptoms(37.9% vs 62.5%) and haemoptysis(16.1% vs 33.0%) than those of PTB group.Positive-sputum(63.2% vs 34.1%),cavity(56.3% vs 13.6%),wide lesions and bilateral lesions on chest radiographs was more common in DM-PTB group than in PTB one.Introversion(OR=1.582, 95%CI:1.063 ～2.355),type 2 DM(OR =2.186,95% CI:1.082 ~4.420)and cavity(OR =2.793,95% CI:1.308 ～5.964)were factors independently associated with positive-sputum TB.The factors related to cavity included diabetes(OR=14.199,95%CI:5.376~ 37.501),cough,postive sputum and lore-up lobe lesion.Conclusion This study confirmed that clinical manifestations and chest radiographs of PTB patients complicated with type 2 DM significantly departed from the typical presentation.Type 2 DM seems to have a negative effect on postive-sputum and cavity.So it should be alarmed that DM-PTB patients who tend to have untypical clinical symptom and higher rate of positive sputum become the reservoirs of infection to cause the transmission of TB.

OBJECTIVETo study the therapeutic effects of posterolateral depression fractures of the tibial plateau through a modified anterolateral approach.

METHODSFrom February 2011 to January 2012,13 patients with posterolateral depression fractures of the tibial plateau were treated through a modified anterolateral approach. There were 8 males and 5 females, ranging in age from 28 to 59 years old (49.2 years old on average). Data from patients were collected retrospectively as follows: X-ray, time of fracture healing and the complications of fracture healing. The patients were evaluated both clinically and radiologically according to the Rasmussen score system.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months (mean 13.7 months). All the patients got bony union. The average radiographic bony union time was 15.1 weeks (ranged, 11 to 17 weeks). No case of secondary articular depression was found. No complications such as malunion or joint stiffness were found. But 1 patient had superficial infection and 1 patient had common peroneal nerve injury. According to the Rasmussen score system,the mean radiological score was 16.50 ± 0.67 (ranged, 13 to 18), and the mean functional score was 25.20 ± 2.21 (ranged, 13 to 30). The mean range of knee motion was (125.3 ± 9.3)° (ranged, 0° to 135°).

CONCLUSIONTreatment of depression fractures of posterolateral tibial plateau with a modified anterolateral approach is a safe method with effective exposure, due to its stable fixation and relatively good outcome with minimal soft-tissue complications. It is regarded as an ideal procedure for depression fractures of posterolateral tibial plateau.

OBJECTIVE: To investigate the facile method for preparation of albendazole sulfoxide, an active metabolite in vivo. METHODS: The reaction condition was investigated according to evaluations to the results of the experiment through temperature, solvent, oxidation agent, reaction time and impurity. RESULTS: The target compound was obtained by oxidation of albendazole with the presence of sodium metaperiodate in glacial acetic acid under low temperature and was free from contamination by impurity albendazole sulfone. Pure product (content >98%) and high yield (>90%percnt;) have been achieved due to reaction selection. CONCLUSION: Oxidation condition is essential to the preparation of albendazole sulfoxide.
