Pancreatic adenocarcinoma ( PAC) is still a refractory human digest malignancies due to multi-faceted causes ,late diagnosis and insensitive to traditional chemo -and radio-therapy .Resistance to apoptosis could be one of the most relevant mechanisms for PAC to escape any non -surgical therapy .This review aims to clear up the main deregulated apoptosis signal pathways over the years and to find out the abnormal molecule tar -get(s),and therefore,provide novel concepts for PAC molecular targeting therapy .

Chinese Journal of Biochemical Pharmaceutics 2015;(6):108-110
Objective To study the effect of purslane decoction on oxidative stress products and soluble protein of senile cataract patients tears.Methods 120 cases of cataract patients (160 eyes) were selected, according to different drugs were randomly assigned to two groups.The control group were treated with Imidacloprid sinnock sodium drops eye drops, 1 drop each time, 4 times per day,the patients in the experimental group on the basis of the control group with Portulaca oleracea decoction 100 mL, for three consecutive months.SOD, MDA, soluble protein level and visual improvement were compared after the end of treatment.Results Compared with control group, the visual acuity of the experimental group was higher(P<0.05), MDA was lower, SOD was higher(P<0.05), soluble protein content was higher(P<0.05).Conclusion Portulaca oleracea decoction can apparently improve the cataract patients with tear of SOD, MDA, soluble protein level and improve visual acuity.

Hepatocellular carcinoma ( HCC ) is one of the commonest malignant tumors in China .The therapeutic effects of conventional therapies including surgery resection at early stage ,chemotherapy or radiothera-py are greatly less than expected .One of the most possible reasons is the blockage of apoptosis in HCC cells .This review collects literatures about the studies on the roles of key signal pathways including RA ,STAT3,PDT,p53,β-catenin,TRAIL,microRNA and RAS in HCC therapy .This study may contribute greatly to providing outline in-sights for using apoptosis induction in liver cancer therapy .We hope it can promote the development liver cancer therapy in China .

Objective To compare the effects and complications of lumboperitoneal shunt ( LP ) and ventriculoperitoneal shunt ( VP ) in the treatment of post?traumatic hydrocephalus. Methods Eighty patients with post?traumatic hydrocephalus treated in the neurosurgery department of Zhangjiagang Hospital of Traditional Chinese Medicine from March 2014 to March 2010 were retrospectively analyzed. The patients were randomly divided into two groups,40 patients treated with LP were assigned into the LP group and 40 patients undergone VP treatment were seen as the VP group. All patients were followed up for 1 year to investigate and compare the symptom improvement rate,neurological deficit score and the incidence of complication of the two groups. Results The total effective rate of hydrocephalus disappearance in the LP group was 41. 50% ( 37/40) and 87. 50%( 35/40) in the VP group. The difference between the two groups was not statistically significant (χ2=0. 556,P=0. 456);the neurological deficit scores before treatment in the LP group and VP group were (28. 35±8. 64) points and (29. 13±7. 98) points,there was no significant difference between the two groups (t=0. 419,P=0. 676) . The difference in the scores of neurological deficit after treatment in the LP and VP group was not statistically significant ( (19. 32±5. 34) points vs. (21. 62±4. 86) points,t=1. 480,P=0. 143),the average scores of neurological deficits in the two groups were significantly better than those before treatment ( t=5. 623, 5. 084,P<0. 001 ) . There was no significant difference in the average score of improvement of urinary incontinence between the two groups before and after treatment ( t=0. 376,1. 265,P>0. 05) ,the average score of urinary incontinence improvement after treatment in both groups were better than those before treatment ( t=4. 891,5. 370,P<0. 001) . In the LP group,the incidence of bleeding,infection,shunt related complications and shunt abnormality were all 2. 50% ( 1/40 ) , the overall complication rate was 10. 00%, the incidence of bleeding,infection,shunt related complications and shunt abnormality in the VP group were 7. 50% (3/40), 10% ( 4/40 ) , 5% ( 2/40 ) 10%, ( 4/40 ) , the overall complication rate was 32. 50%, there was significant difference between the two groups (χ2=6. 050,P=0. 014) . Conclusion LP and VP have significant curative effect on the treatment of post?traumatic hydrocephalus,but the overall incidence of LP complication after 1 year is significantly lower than that of VP,and is worth popularizing widely in clinical practice

Some types of bacteria swim through rotating their flagella. The swimming mechanism of bacteria during flagella bundling and tumble process is analyzed. The effects of body rotation and flagellum′s polymorphic transitions on bundling processes and the wall effect phenomenon are also discussed. Finally, based on dynamics similarity, a new microrobot module is put forward to further studying the flagella swimming phenomena. The research would be very helpful for constructing the bionic swimming robots under the low Reynolds number.

AIM:To observe the clinical effect of femtosecond laser assisted penetrating keratoplasty.
METHODS: Twenty-four cases ( 24 eyes ) with corneal lesions were performed with femtosecond laser assisted penetrating keratoplasty. Preoperative and postoperative endothelial cell density and visual quality were compared.RESULTS: One week after operation, corneal grafts were clear in 21 eyes (87. 5%), mild cloudy in 3 eyes (12.5%);visual acuity ≥0. 5 in 18 eyes (75. 0%), 0. 2 ~0.4 in 6 eyes ( 25. 0%). After 3mo the mean corneal astigmatism was 2. 16±0. 21D ( range 2. 25 ~ 3. 09D). Compared to conventional penetrating keratoplasty which mean corneal astigmatism was average 3. 67±0. 38D after operation, there was significant difference between two groups ( P< 0. 05 ). There were significant differences between preoperative and postoperative visual acuity and astigmatism (both P<0. 05).
CONCLUSION: Femtosecond laser assisted penetrating corneal transplantation operation can improve patient's visual quality. And compared to traditional penetrating keratoplasty astigmatism decreased significantly, incision can be made in individual shape more precisely and neatly.
