AIM:To examine the efficacy and safety of cryotherapy in the management of Fusarium corneal ulcer.
METHODS: Retrospective contract analysis of the clinical data of 41 patients ( 41 eyes ) who infected with Fusarium corneal ulcer. All of them underwent focal lesion keratectomy combined with amniotic membrane transplantation between January 2010 and May 2013. The cryotherapy treatment group of 22 cases (22 eyes), non-cryotherapy group of 19 cases ( 19 eyes ) . All the cases were followed up for 3 ~12mo. We analyzed the healing of corneal ulcer, corneal neovascularization, postoperative visual acuity, complications and ulcer recurrences.
RESULTS: There were no significant difference for the two groups at the cure rate and the recovery rate, the corneal neovascularization and postoperative visual acuity (P>0. 05). The total effective rate and corneal healing time in cryotherapy group was significantly higher than that in non - cryotherapy group ( P < 0. 05 ). The postoperative visual acuity of two group were higher than that of preoperatively ( P < 0. 05 ). There was no complication occurred in cryotherapy group while there was 1 patient of secondary glaucoma in non-cryotherapy group.
CONCLUSION: Cryotherapy is an effective and safe method for the treatment of Fusarium corneal ulcer.

Objective To value the clinical application of diffusion tensor imaging (DTI) in cerebral diseases. Methods Six volunteers and 6 patients (including 3 patients with ischemic stroke and 3 patients with glioma) were examined by DTI and T1weighted, T2weighted MR scan. All data were processed with DtiStudio software to show the white matter fiber tracts. The fractional anisotropy (FA) of the diffusion tensor were measured between the affected and the unaffected side. Results The white matter fiber tract could be observed clearly on the FA map. The pyramidal tract with different degree disruption could be showed in 3 patients with ischemic stroke. Compression, displacement, infiltration or destruction of pyramidal tract, corpus callosum or internal capsule and external capsule could be seen in 3 patients with glioma, and FA was significantly reduced on the affected side as compared to the unaffected side. Conclusion Diffusion tensor imaging is useful in observing the damage and displacement of the white matter fiber tracts in vivo, beneficial to the surgical plan for patients and prognosing recovery of function.

OBJECTIVETo Understand the characteristics of the common complications in the gastric malignant tumor inpatients in our country, the related traditional Chinese and western medicine combined usage.

METHODBy using the method of frequency analysis and correlation, analysis the diagnostic and Prescribing information in HIS database of 20 national first-class ternary general hospital inpatients.

RESULTThe most common coexistent disease are malignant tumor in other parts, benign tumor. The most common complications are serous cavity effusion, lung infection, abnormal liver function. In other parts malignant tumor, more than 50% with advanced gastric malignancy; in other parts benign tumor, 86.00% located in the digestive and Urinary system, in the complications, digestive system diseases accounted for 23.80%; further according to the association rules of data mining, and calculate the combination scheme of the most commonly used for acid suppression drugs in combination with the centralizer and eliminate pathogenic traditional Chinese medicine (TCM).

CONCLUSIONIn the real world, most of the gastric malignant tumor disorder crowd is in the advanced stage, with lymph nodes and other parts of the transfer; and at the same time to incorporate the spleen and kidney disease in TCM zang-fu organs dialectical, should notice the reach mark early intervention, achieve the purpose of cure not ill; acid suppression hemostatic drugs combined the centralizer and eliminate pathogenic the three medicine combined treatment of Chinese traditional medicine is relevant.

OBJECTIVETo study the characteristics and regular pattern of the medicine in common use and combined medication in patients of acute pancreatitis in real world.

METHODCollect the information of 5 433 acute pancreatitis patients in 19 grade IIIA general hospitals in China, analysis by descriptive statistics and association rule.

RESULTIn the 5 433 patients of acute pancreatitis, the glycyrrhizic acid injection and somatostatin are the frequency top used Chinese traditional and western medication. Glycyrrhizic acid injection, somatostatin and insulin are the frequency top used drug combination pattern.

CONCLUSIONThe Chinese and western integrative medicine drug use pattern are accord with the clinical guideline of acute panceatitis. The hepatic and renal function, blood routine and coagulation function should be monitored when the medicines are used.

Objective To establish and evaluate a gene microarray for determination katG mutations of Mycobacterium tuberculosis isolates associated with resistance to isoniazid(INH).Methods A panel of probes were designed and gene chips were prepared by dotting.Mycobacterium tuberculosis isolates resistance to 5 drugs was determined by proportional dilution methods.Amplicons of Mycobacterium tuberculosis isolates were detected by our chip and sequenced.Results The drug resistance rate of the isolates to at least one of the anti-tuberculosis drugs was 70.8%(97/137).45 strains out 137 Mycobacterium tuberculosis isolates was resistant to INH(32.8%).katG was successfully amplified from 100% of the susceptible strains and 88.9%(40/45)resistant strains.4 of 45 INH resistant isolates' katG were deleted.27 of 40(67.5%) katG has been detected to have katG 315 codon mutations.The mutations were 315 AAC(Asn,13/40), ACC(Thr,6/40),ACA(Thr,4/40),ATC(Ile,2/40),AGC(Arg,2/40).The mutation rate of katG analyzed by gene chips we prepared were identical to katG sequencing.Conclusion The gene microarray techniques we developed for determination of Mycobacterium tuberculosis resistance to INH are specific, sensitive and may be used as an alternative in clinical laboratory.

BACKGROUNDThe Toll-like receptors (TLRs) represent a group of single-pass transmembrane receptors expressed on sentinel cells that are central to innate immune responses.The aim of this study was to investigate the presence of soluble TLRs in pleural effusions, and the diagnostic values of TLRs for pleural effusion with various etiologies.

METHODSPleural effusion and serum samples were collected from 102 patients (36 with malignant pleural effusion, 36 with tuberculous pleural effusion, 18 with bacterial pleural effusion, and 12 with transudative pleural effusion). The concentrations of TLR1 to TLR10 were determined in effusion and serum samples by enzyme linked immunosorbent assay. Four classical parameters (protein, lactate dehydrogenase, glucose and C-reactive protein (CRP)) in the pleural fluid were also assessed. Receiver-operating characteristic curves were used to assess the sensitivity and specificity of pleural fluid TLRs and biochemical parameters for differentiating bacterial pleural effusion.

RESULTSThe concentrations of TLR1, TLR3, TLR4, TLR7 and TLR9 in bacterial pleural effusion were significantly higher than those in malignant, tuberculous, and transudative groups, respectively. Analysis of receiver operating characteristic curves revealed that the area under the curves of TLR1, TLR3, TLR4, TLR7 and TLR9 were 0.831, 0.843, 0.842, 0.883 and 0.786, respectively, suggesting that these TLRs play a role in the diagnosis of bacterial pleural effusion. Also, the diagnostic value of TLRs for bacterial pleural effusions was much better than that of biochemical parameters (protein, lactate dehydrogenase, glucose and CRP).

CONCLUSIONSThe concentrations of TLR1, TLR3, TLR4, TLR7 and TLR9 appeared to be increased in bacterial pleural effusion compared to non-bacterial pleural effusions. Determination of these pleural TLRs may improve the ability of clinicians to differentiate pleural effusion patients of bacterial origin from those with other etiologies.
