AIM: To discuss the clinical applications of methods to localize nasal cut ends and the effects of Z-plasty in the surgeries for lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption.
METHODS: From September, 2010 to October, 2013, a total of 37 patients ( 37 eyes ) with lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption were operated for anastomosis of lacrimal canaliculi disruption and suture of lower eyelid longitudinal. Different methods to search for the nasal cut ends of lacerated lacrimal canaliculi, such as “under a microscope directly”, “guided by probing needle” and“pigtail curved probe”. Then, to repair lower eyelid longitudinal laceration with Z-plasty transposition flaps. Follow up was 3mo~2a after operation.
RESULTS: All nasal cut ends could be found successfully on 37 patients;Lacrimal duct unobstructed in 31 patients (83. 8%), improved in 5 patients (13. 5%), invalid in 1 patient (2. 7%),the overall successful rate was 97. 3%; the eyelids repair was satisfactory, small scars, the appearance and function was normal.
CONCLUSION: The nasal cut ends can be found successfully by “directly under a microscope”, “guided by probing needle” and“pigtail curved probe”;the effect of silicone drainage tube used as lacrimal canaliculi bracket is satisfactory; most patients gained excellent recovery for both appearance and function after Z-plasty.

Objective To construct the eukaryotic expression plasmids of human Fas and TNFR1 gene(pcDNA3.0-hFas and pcDNA3.0-hTNFR1)and microRNA(miRNA)expression plasmid of hFas and hTNFR1 named p-hFasmiRNA and p-hTNFR1miRNA,and to investigate their inhibitory effects in vitro.Methods The eukaryotic expression plasmids of human Fas and TNFR1 gene were constructed(pcDNA3.0-hFas and pcDNA3.0-hTNFR1)and have been shown successfully to express hFas and hTNFR1 protein.miRNA expression plasmids of hFas and hTNFR1 named p-hFasmiRNA and p-hTNFR1miRNA complimentary to the sequence responsible for hFas and hTNFR1 respective were constructed,meanwhile irrelevant miRNA plasmid was used as a control.By respective co-transfection of p-hFasmiRNA and pcDNA3.0-hFas,p-hTNFR1 miRNA and pcDNA3.0-hTNFR1 expression construct into 293T cells,the inhibition of hFas and hTNFR1 expression was analyzed by real-time PCR and Western blot.Results The experiments showed the significant inhibitory effect of p-hFasmiRNA on hFas and p-hTNFR1miRNA on hTNFR1 expression at 48 h post-transfection both at RNA level and protein level as well in 293T cell lines with the inhibitory efficiency being as high as 87% for hFas and 80% for hTNFR1,respectively.Conclusion The p-hFasmiRNA and p-hTNFR1miRNA were constructed successfully,and it was verified that they could specifically inhibit the hFas and hTNFR1 expression at the cellular level.

Armillariella tabescens EJLY2098 was induced to produce ?-mannanase with konjac fine flour (Amorphopallus rivieri) as single carbon source. This induced enzyme was then purified using DEAE ion exchange chromatography and named atMAN47. Zymologic analysis showed that the molecular weight of this ?-mannanase was approximately 47 kD. The enzyme was stable when pH ranged from 5.0 to 6.5 and could be activated by Na+ and Ba2+. With an optimal temperature of 50?C. Action mode analysis of TLC revealed that the enzyme belonged to the endo-?-mannanase family. Being a meta-acid endo-?-mannanase, it was suitable to be applied to feed industry with a promising future as an enzyme preparation.

Objective To discuss the clinical efficacy of closed reduction and plaster splint fixation ( CRPSF) in the treatment of gerontal patients with distal radius fractures ( DRF) .Methods 76 elderly patients with DRF who treated by CRPSF were selected .According to AO classification of fractures ,the patients were divided into three groups,the A group had 27 cases;B group had 26 cases,C group had 23 cases.The treatment effect was evalua-ted by analyzing the follow-up data,the corresponding imaging measurement parameters and clinical scores .Results All patients had 12-month clinical and imaging follow-up.In the last follow-up, the arm-shoulder-hand dysfunction score and palmar angle ,ulnar deviation angle of A and B group were significantly better than those of C group , the differences were statistically significant(all P<0.05),the difference between A and B group was not statistically sig-nificant (P>0.05).In the last follow-up,the satisfaction score of C group was slightly lower than that of the A or B group,but had no statistically significant difference (P>0.05).Conclusion CRPSF in the treatment of gerontal pa-tients with DRF has good function and imaging effects ,and the improvement level has a certain relationship with the degree of fracture,but has no significant impact on the patients'satisfaction.

Objective To evaluate the clinical effect of computed tomography?guided visceral nerve plexus ethanol neurolysis through post?curs of diaphragm approach in the treatment of patients with pancreatic cancer pain using,and study the safety and life quality improvement of patients . Methods A total of 58 patients suffered from pancreatic cancer pain,who were treated in the department of pain medicine of the First Hospital of China Medical University from October 2013 to December 2014,were recruited for the study. The patients were divided into two groups according to the willing of the patients and their families,group A(32 cases)was treated with Visceral Nerve Plexus ethanol Neurolysis,while group B(26 cas?es)was treated with oral opioid drugs. The analgesic effect,changes in the amount of opioid drugs,changes in the PSQI scores and the improvement of quality of life were evaluated before treatment and 1 day(T1),15 days(T15),30 days(T30),60 days(T60)after treatment. Record the adverse reactions in the course of treatment. Results All the patients of group A successfully received visceral nerve plexus ethanol neurolysis,the VAS scores,Karnofsky scores,and PSQI scores of all the observed time points(after the operation)were statistically different compared to those before treatment and group B. Statistically difference was also observed in quality of life between two groups(P<0.05). The amount of opioid drugs of group B was statistically increased than that of group A(P<0.01).The most common side effects in Group A were postural hypotension(6 cases),diar?rhea(2 cases),and intercostal neuralgia,while nausea(20 cases),constipation(11 cases)and dizziness(8 cases)were seen in the Group B. Con?clusion Visceral nerve plexus ethanol neurolysis through post?curs of diaphragm approach by the guide of CT is effective and safe for the patients with pancreatic cancer pain,and the complications were totally acceptable.

This study was aimed to investigate on effect of As(2)O(3) on expressions of COX-2, MMP-2 and MMP-9 in SGC7901 and K562 cells. SGC7901 and K562 cells were cultured in RPMI 1640 medium and were inoculated in culture medium with different concentrations of As(2)O(3) and at different times. Expressions of COX-2, MMP-2 and MMP-9 in SGC7901 and K562 cells were measured by using Western blot, while the levels of COX-2 mRNA and MMP-2 mRNA were measured with fluorescence quantitative RT-PCR. The results showed that the expression of COX-2, MMP-2 and MMP-9 decreased in dose- and time-dependent manners after treating with As(2)O(3). The levels of COX-2 mRNA and MMP-2 mRNA reduced in groups treated with As(2)O(3). In conclusion, As(2)O(3) inhibits expressions of COX-2, MMP-2 and MMP-9 in K562 and SGC7901 cells, suggesting that As(2)O(3) inhibits tumor development through its effect on angiogenesis involved in solid and hematologic malignancies.
