AIM: To quantitatively investigate transforming growth factor-β(TGF-β) and its receptors in normal bulbar conjunctival tissues and pterygium tissues. METHODS: Thirty cases of pterygium patients were randomly selected to undergo surgical resection of pterygium lesion, and the normal margin of bulbar con-junctival tissues were collected as control. Gene expres-sion was detected quantitatively by the method of quantitative real-time PCR (QRT-PCR) analysis. RESULTS: The expression level of TGF-β1 and TGF-β2 was 4.26×10-7±1.45×10-7 and 1.08×10-10±0.68×10-10 in normal bulbar conjunctival tissues, while 10.67×10-7±7.47×10-7 and 8.23×10-11±6.63×10-11 in pterygium tissues. The expression level of TGF-βRⅠand TGF-βRⅡwas 0.003015±0.0036 and 5.33×10-5±5.05×10-5in normal bulbar conjunctival tissues, while 0.000379±0.000281 and 1.002×10-5±9.04×10-6 in pterygium tissues. The expression level of TGF-β1 and TGF-β2 in pterygium was elevated (P<0.01). TGF-β1 expression level in pterygium increase 2.9±2.8 times than in normal conjunctiva. TGF-β2 expression level in pterygium increase 7.5±1.4 times than in normal conjunctiva. The expression level of TGF-βRⅠin pterygium was significantly lower (P<0.05). The expression level of TGF-βRII in pterygium was significantly lower (P<0.01). CONCLUSION: QRT-PCR is an effective method to quantitatively detect gene expression in eye. The upregulation of TGF-β1 and TGF-β2 and downregulation of their receptors expression may play an important role in the pathogenesis of pterygium, which is noteworthy further investigation in diagnosis and treatment of pterygium.real-time PCR; gene expression

Sulfate-reducing bacteria (SRB) are widespread in the environment. SRB are obligate anaerobes and capable of dissimilatory reduction of sulfate. SRB have application prospects in the control of environmental pollution due to that many pollutants can be removed by SRB. The biological characteristics and metabolic mechanisms of SRB are introduced, and the application of SRB in the treatment of environmental pollution is described in this paper. The research progress of Cr(Ⅵ ) reduction and Cr(Ⅵ ) removal from wastewater by SRB is reviewed, and future direction of research on the control of Cr(Ⅵ ) pollution by SRB is also analysed.

Objective To investigate clinical features and prognostic factors in acquired immune deficiency syndrome (AIDS) patients with opportunistic infections.Methods Forty-two cases of AIDS patients with opportunistic infections were enrolled in this study.Clinical data and major factors affecting the prognosis were analyzed using Logistic regression.Results Bacterial infection was the first etiological factor(57.1%) of opportunistic infections in AIDS patients.Eighty-three point three percent of patients infected with more than two kind of etiological agents.Fifty-seven point one per- cent of cases were infected in multiple sites.CD4~+ T cells count was associated with the opportunistic infections.Conclusions The CD4~- T lymphocytes count is the key factor affecting the prognosis of AIDS patients with opportunistic infections.The average of CD4~+ T lymphocytes count is significant- ly related with the major opportunistic infections in AIDS paitents.

Objective To explore clinical application of single utility port or single port video-assisted thoracoscopic lobectomy.Methods Conducting a prospective study to 191 patients with lung disease who underwent complete video-assisted thoracoscopic surgery (VATS) lobectomy in Department of Thoracic Surgery of The People's Hospital of Wuhan University from June 2013 to Dec 2014.Results Of the 191 patients, 35 underwent left upper lobectomy, 42 underwent left lower lobectomy, 43 underwent right upper lobectomy, 11 underwent right middle lobectomy, 47 underwent right lower lobectomy, and 13 underwent bilobectomy.Operations were successful in all patients with 3 patients transferred for open thoracotomy for severe adhesion or bleeding.A total of 7 of 78 upper lobectomy and 8 of 113 middle or lower lobectomy was done with adding another incision for severe adhesion.The mean operative time was 50 ～ 190 (80.3 ±43.2) min.The mean blood losing was 90 ～ 350 (145.4 ± 56.2) ml.Thirty nine patients underwent upper lobectomy, who were placed two chest tubes, respectively.The upper chest drainage duration was (1.5 ±0.8) d, and the lower chest drainage duration was (4.2 ± 1.3) d.Forty eight patients underwent lower lobectomy, middle lobectomy, or bilobectomy, who were placed one chest tube, respectively.The chest drainage duration was(4.0 ± 1.7)d.The mean recovery time after operation was (6.1 ± 2.5) d.Seventy six patients were diagnosed with lung cancer, and the average number of dissected lymph nodes from each patient was (14.7 ±6.9).The lung cancer was classified as tumor node metastasis (TNM) stage Ⅰ A, Ⅰ B,ⅡA, ⅡB and ⅢA in 67, 61, 34, 22 and 7 cases, respectively.No serious complications, such as bronchopleural fistula or death, occurred in perioperation.Conclusions In consideration of placing two chest tubes after upper lobectomy and placing one chest tube after lower lobectomy, middle lobectomy, or middle and lower lobectomy, we think single utility port-VATS (2-port) for upper lobectomy and single port-VATS lobectomy for lower lobectomy, middle lobectomy, or middle and lower lobectomy are technically safe and have the advantages of drainage, lessening pain, rapid postoperative recovery, and have no significant difference in operation time, the incidence of complications and the number of removed lymph nodes, compared to traditional 3-port-VATS.

A total of 160 type 2 diabetic patients were divided into microalbuminuria(42 cases)and normoalbuminuria(118 cases)groups.Multivariate analysis demonstrated that the presence of microalbuminuria was independently associated with brachial-ankle pulse wave velocity(baPWV)and intima-media thickness(both P

OBJECTIVETo study the change in expressions of nerve growth related protein (GAP-43) and neurofilament (NF) after experimental injury of spinal cord, and the regulatory effect of Chinese medicine Suifukang (SFK) on them.

METHODSForty-eight from the 54 selected adult SD rats were established into spinal cord injury model by making hemitransection at the T12 level, and randomly divided into two groups, the SFK group feed with SKF contained liquor and the model group feeding with equal volume of saline. The another 6 rats were untreated and taken as the normal group. All rats were sacrificed in batches at different time points of day 3, 7, 15 and 30 after modeling. The spinal cord was obtained for determining the optic density (OD) of positive expression of GAP-43 and NF with immunohistochemical stain by microscopic and semi-quantitative image analysis.

RESULTS(1) OD of NF in the model group was obviously decreased on day 7, showing significant difference to that in the normal group and that in the SFK group (P < 0.05), and it maintained at low level after then, while the OD of NF in the SFK group was obviously higher than that in the model group (P < 0.05), it arrived the peak on day 15 and then dropped near the level in the normal group on day 30; (2) OD and of GAP-43 in the model group obviously decreased on day 3 (P < 0.05), showing significant difference to that in the normal group (P < 0.05), then it returned to approach to the level in the normal group on day 7. It was higher in the SFK group than in the model group on day 3, and maintained the high level to day 7, at that time, it was still higher than that in the model group and also higher than that in the normal group (P < 0.05).

CONCLUSIONSFK can promote the repair and regeneration of injured nerve fibers in spinal cord by up-regulating the expression of GAP-43 and NF.
