AIM:To study the changes of tear film and ocular surface after the coaxial micro incision 2. 2mm and 2. 8mm in the phacoemulsification.
METHODS:Eighty-six patients ( One hundred and six eyes ) from 2014/06 to 2016/01 in our hospital were enrolled. The patients were randomly divided into two groups. Forty-four patients ( Fifty-three eyes) in group A: coaxial 2. 2mm micro- incision phacoemulsification cataract extraction and intraocular lens(IOL) implantation;Forty-two patients ( Fifty-three eyes ) in group B: the conventional coaxial 2. 8mm small incision phacoemulsification cataract extraction and IOL implantation. The break up time ( BUT) , dry eye symptom ( DES) score, Schirmer's I test ( SⅠt ) and lid-wiper epitheliopathy ( LWE ) score were assessed preoperatively and postoperatively.
RESULTS:At 1wk, 1 and 2mo postoperatively, the BUT in two groups decreased after operations, and the BUT of group B was significantly lower than those of group A, the differences were statistically significant ( t = 3. 098, 4.512, 4.329; all P < 0. 05 ). The DES score in two groups increased, the DES score of group B was significantly higher than those of group A and the differences were statistically significant (t=-9. 449, -10. 029, -7. 141; all P<0. 05). The SⅠt in two groups increased after operations, the SⅠt of group B was significantly higher than those of group A and the differences were statistically significant (t=-6. 293, -4. 009, -3. 283; all P<0. 05). The LWE score in two groups increased after operations, the LWE score of group B was significantly higher than those of group A and the differences were statistically significant (t=-6. 542,-5. 125, -3. 632; all P<0. 05). At 6mo postoperatively, compared with the preoperative data, the BUT, DES score, S Ⅰ t and LWE score in group A showed no statistically significant differences (t=0. 659, 1. 276, 0. 548, 0.169; P>0. 05). The BUT, DES score, SⅠt and LWE score in group B showed statistically significant differences (t=-4. 063, 7. 306, 3. 621, 4. 208;all P<0. 05).CONCLUSION:Ocular surface has less damage and tear film has little influence at early stage after the coaxial 2.2mm microincision phacoemulsification, compared with the conventional coaxial 2. 8mm incision phacoemulsification surgery.

Objective To evaluate the efficacy of DSA-guided percutaneous transhepatic gallbladder catheter drainage (PTGCD) in treating aged patients with acute cholecystitis complicated by severe diseases. Methods The clinical data of 15 aged patients with acute cholecystitis or complicated by severe diseases, who were encountered at authors’ hospital in the past three years and were treated with PTGCD, were retrospectively analyzed. The clinical results were discussed. Results PTGCD was successfully accomplished with single procedure in all 15 patients. Abdominal pain was relieved within one to three days, and the abdominal symptoms and signs subsided or disappeared. Reexamination of routine blood test showed that the white blood cell count decreased to normal range in 1 - 2 weeks, and complete cure was achieved in some patients. Secondary surgery was carried out in some patients after the clinical condition was improved. During the follow-up period no complications occurred in all patients except one who developed biliary leakage after the catheter was retrieved two weeks after the treatment. Conclusion For the treatment of complicated acute cholecystitis in aged patients who are not suitable to receive surgery, DSA-guided percutaneous transhepatic gallbladder catheter drainage is an ideal therapeutic means as it can significantly relieve clinical symptoms.

In this study, cardiotonic and cardiotoxic effects of Buthus martensi Karsch (BmK) I, a modulator of voltage-gated sodium channels, were investigated on the isolated rat hearts. The results showed that BmK I evoked complex effects characterized by a change in both cardiac mechanical and electrical activity. Langendorff perfusion showed that: (1) maximal left ventricular developed pressure (LVDP(max)) and dp/dt(max) were markedly increased by BmK I (0.5-10 micromol/L) in a dose-dependent manner (n=6, P<0.05), positive chronotropic effects were also induced by BmK I (n=6, P<0.05); (2) negative inotropic action and bradycardia could be elicited at a larger dose of BmK I (20 micromol/L); (3) the coronary flow varied inversely with the positive inotropic effects, coronary flow reduced during positive inotropic effects from 14.5 to 8.6 ml/min after administration of 500 nmol/L BmK I (n=6, P<0.05). In addition, tachycardia and complex cardiac arrhythmias were induced by BmK I (0.5-10 micromol/L). The modulating of BmK I on the heart mechanical, electrical activity could be partially recovered after washing. As propranolol was applied to block the release of catecholamines before administration of BmK I, suggesting that the changes in cardiac mechanical and electrical activity induced by BmK I might not due to catecholamine release from the nerve terminal and subsequent stimulation of the beta-adrenoceptor but attributable to the modulation of BmK I on cardiac voltage-gated sodium channels.

Objective To investigate the effect of L-camitine on renal ischemia-reperfusion (IR) injury (IRI) and Nrf2-ARE signaling pathway in rats.Methods Rats were randomly separated into the following experimental groups:control group (group C),IRI group (group I) and L-carnitine group (group L).Rats accepted no treatment of ischemic reperfusion in group C.In groups I and group L,the renal IRI model was established.L-carnitine was injected through the tail vein in group L,while the equal volume of saline was injected in group C and group I.Rats were killed at 3,6,and 24 h after IR.The levels of serum creatinine (Cr) and blood urea nitrogen (BUN),the activity of superoxide dismutase (SOD) and the content of malonaldehyde (MDA) in serum were measured.The histopathological lesions were observed in renal tissues after 24-h IR.RT-PCR was used to detect the levels of Nrf2,HO-1 and γ-GCS mRNA.Western blotting and immunohistochemistry were used to detect the levels and localization of Nrf2 protein in renal tissues after 6-h IR.Results The levels of Cr and BUN in group I and group L were higher than those in group C at 3 h after IR.At 6 h after IR,the levels of Cr and BUN in group L were lower than those in group I (P<0.01 ).At 24 h after IR,the levels of Cr and BUN in group L were still lower than those in group I though both of them were reduced (P<0.05).At all time points,the activity of SOD in group L was higher and the content of MDA was lower than those in group I (P< 0.05). As compared with group I,the renal histopathological lesions were alleviated in group L at 24 h after IR.At 6 h after IR,levels of Nrf2,HO-1,γ-GCS mRNA and Nrf2 protein in group I were increased as compared with group C,but decreased as compared with group L.Beyond that,the expression of nuclear Nrf2 protein in group L was higher than that in group I.Conclusion L-carnitine can protects the kidney against IRI significantly,which may be due to the up-regulated expression of antioxidant genes by activating the Nrf2-ARE signaling pathway.

OBJECTIVETo summarize the effectiveness of Chinese and Western integrative medicine in treating medium and advanced lung cancer, and to provide guidelines for clinical application.
METHODSFor this metaanalysis, a comparative search of Chinese medicine data in Chinese National Knowledge Infrastructure (CNKI) and Chinese BioMedical Literature Database (CBM) was undertaken to identify articles related to randomized comparative research of Chinese and Western integrative medicine in treating medium and advanced lung cancer between 1996 to 2006. Quality of life (QOL) was estimated using RevMan 4.2 software for data processing, adopting the odd ratio (OR) and the 95% confidence interval (CI).
RESULTSThrough meta-analysis of 10 qualified articles, the results were as follows: the merging effectiveness of QOL [OR=3.80, 95% CI (2.65, 5.47)]; the rate of survival [OR=3.44, 95% CI (2.04, 5.80)]; the tumor response rate [OR=1.88, 95% CI (1.37, 2.58)]; the tumor developing rate [OR=0.33, 95% CI (0.23, 0.48)]. Significant differences existed between the Chinese and Western integrative medicine treatment group and the Western treatment group (P<0.01).
CONCLUSIONSChinese and Western integrative medicine treatment of medium and advanced lung cancer has shown to improve patients' QOL and survival rate; it also can control tumor development in the short term.
