Objective To study the effect of the Aiyishu injection combined with chemotherapy for middle and advanced cancer patients in the near future curative effect and survival quality.Methods 127 middle and advanced cancer patients were randomly divided into two groups,71 cases in therapeutic group and 56 cases in control group.The therapeutic group and control group both choose the same sickness plants and combined chemotherapy plan of pathology,therapeutic group added the Aiyishu injection 40 ml to drip. The treatment course lasted 14 days,with 3～4 courses,Simple chemotherapy was used in the control group. Results In the therapeutic group,there were 3 cases of complete response(CR),23 cases,of partial response (PR),the rate of response is 36.62 %(26/71).In the control group,there was 1 case of complete response(CR), 10 cases of partial response(PR),the rate of response is 19.64 %(11/56).There was significant difference be- tween the two groups(P0.05),whereas it declined significantly in the control group after chemotherapy(P

The purpose of the study is to construct R8 peptide (RRRRRRRR) and pH sensitive polyethylene glycols (PEG) co-modified liposomes (Cl-Lip) and utilize them in breast cancer treatment. The co-modified liposomes were prepared with soybean phospholipid, cholesterol, DSPE-PEG2K-R8 and PEG5K-Hz-PE (pH sensitive PEG). The size and zeta potential of Cl-Lip were also characterized. The in vitro experiment demonstrated that the Cl-Lip had high serum stability in 50% fetal bovine serum. The cellular uptake of Cl-Lip under different pre-incubated conditions was evaluated on 4T1 cells. And the endocytosis pathway, lysosome escape ability and tumor spheroid penetration ability were also evaluated. The results showed the particle size of the Cl-Lip was (110.4 ± 5.2) nm, PDI of the Cl-Lip was 0.207 ± 0.039 and zeta potential of the Cl-Lip was (-3.46 ± 0.05) mV. The cellular uptake of Cl-Lip on 4T1 cells was pH sensitive, as the cellular uptake of Cl-Lip pre-incubated in pH 6.0 was higher than that of pH 7.4 under each time point. The main endocytosis pathways of Cl-Lip under pH 6.0 were micropinocytosis and energy-dependent pathway. At the same time, the Cl-Lip with pre-incubation in pH 6.0 had high lysosome escape ability and high tumor spheroid penetration ability. All the above results demonstrated that the Cl-Lip we constructed had high pH sensitivity and is a promising drug delivery system.

Objective To investigate the efficacy and safety of clopidogrel hydrogen sulfate plus nimodipine in treating transient cerebral ischemic attack.Methods A total of 159 outpatients and inpatients with transient cerebral ischemic attack in the neurosurgery department and the neurology outpatient department of our hospital from January 1,2012 to September 1,2016 were divided into 3 groups.The group A(43 cases) orally took clopidogrel hydrogen sulfate plus aspirin;the group B (51 cases) treated with oral clopidogrel hydrogen sulfate plus nimodipine;the group C(65 cases) was treated with clopidogrel hydrogen sulfate plus nimotop.The curative effects were observed in 3 groups.The differences of PT.APTT,FIB and PLT in 3 groups were compared between before and after treatment.Results The total effective rate of the group A and C was significantly better than that of the group B(P<0.05),the curative effect had no statistical difference between the group A and C (P>0.05);the effect of the group B and group C on coagulation was superior to that of the group A(P<0.05).The three group had no severe bleeding events(cerebral bleeding,etc.),the difference was statistically significant.Conclusion Clopidogrel hydrogen sulfate combined with nimotop can significantly reduce the frequency of transient cerebral ischemic attack,has little influence on the coagulation indicators,and is safe and effective.

Objective:To observe the inhibiting effects of manual acupuncture(MA)on bladder cell apoptosis in rats with diabetic neurogenic bladder(DNB)based on the protein and mRNA expression of B-cell lymphoma-leukemia(Bcl)-2,Bcl-2-associated X(Bax)protein,caspase-3,and the protein expression of α-smooth muscle actin(α-SMA),transforming growth factor(TGF)-β in the bladder tissue. Methods:A DNB rat model was established via intraperitoneal injection of streptozotocin(STZ).The rats were randomly divided into a control group,a model group,and an MA group,with 10 rats in each group.For the MA group,MA was applied after modeling.The body mass,fasting blood glucose(FBG),bladder wet weight,and bladder histomorphology were observed.Protein and mRNA expression levels of Bcl-2,Bax,and caspase-3 and the protein expression of α-SMA and TGF-β in the bladder tissue were determined.The apoptotic index of bladder cells was also evaluated. Results:After STZ injection,compared with the control group,the model group and the MA group both showed higher FBG from week 3 and lower body mass from week 9(P<0.05),and had a larger bladder wet weight(P<0.05).Compared with the model group,the MA group showed a smaller bladder wet weight(P<0.05).The histopathological evaluation indicated that MA improved muscle fiber alignment and detrusor cell compensatory hypertrophy in the bladder tissue.In addition,compared with the control group,the apoptotic index increased significantly in the model group and the MA group(P<0.05);the protein and mRNA expression levels of Bax and caspase-3 and the protein expression level of TGF-β in the bladder tissue in the model group and the MA group increased significantly(P<0.05),while the protein and mRNA expression levels of Bcl-2 and the protein expression level of α-SMA in the bladder tissue decreased significantly(P<0.05).Compared with the model group,the apoptotic index of the MA group decreased significantly(P<0.05);the protein and mRNA expression levels of Bax and caspase-3 and the protein expression level of TGF-β in the bladder tissue decreased significantly(P<0.05),while the protein and mRNA expression levels of Bcl-2 and the protein expression level of α-SMA in the bladder tissue increased significantly(P<0.05). Conclusion:MA can protect the bladder by inhibiting the excessive apoptosis of bladder cells,which may be related to the down-regulation of Bax and caspase-3 proteins and mRNAs and TGF-β protein expression,and the up-regulation of Bcl-2 protein and mRNA and α-SMA protein expression.

OBJECTIVETo investigate the clinical effects of 360 degree circular decompression and transpedicle screw fixation to treat the ossification of thoracic posterior longitudinal ligament by posterior approach.

METHODSFrom December 2009 to November 2013, 18 patients with ossification of thoracic posterior longitudinal ligament ossification were treated with 360 degree circle decompression and transpedicle screw fixation by posterior approach. There were 8 males and 10 females,ranging in age from 32 to 67 years old, with an average of 51 years old. Four patients were accompanied with ligamentum flavum ossification. Longitudinal ossifications in 5 cases were located in the upper thoracic vertebra and 13 cases in the middle and lower thoracic vertebra. Five cases were typical type, 4 cases were segmental type, 6 cases were continuous type and 3 cases were mixed type. All the patients had the posterior spinal canal decompression combined with longitudinal ligament resection, interbody fusion with bone graft and internal fixation surgeries. The operation time,blood loss and complications were recorded. JOA score were applied to evaluate the neurological function recovery pre-surgery, 2 days post-surgery and the latest follow-up. The surgery effects were evaluated by Epstein-Schwall method.

RESULTSThe operation time ranged from 3 to 6 hours (mean, 4.2 hours). The blood loss ranged from 800 to 4 000 ml (mean, 1 800 ml). All the patients were followed up, and the duration ranged from 6 months to 3 years, with a mean of 1.8 years. The JOA score increased from preoperative 4.30 ± 2.60 to 7.60 ± 2.40 2 days after surgery, and 7.80 ± 1.90 at the latest follow-up (t = 4.61, P < 0.001). The JOA scores between 2 days after surgery and the latest follow-up had no significant differences (t = 0.28,P = 0.78). The neurological recovery rate was 74% 2 days after surgery and 71% at the latest follow-up. There were 4 cases got an excellent result,10 good,3 fair and 1 poor according to Epstein-Schwall evaluation method. Four patients had cerebrospinal fluid leakage, 3 patients had intercostal nerve paralysis or pain, and 1 patient had superficial incision infection. The neurological function in 3 patients became worse in the second day posteratively , and among them, 2 patients were recovered at the latest follow-up and 1 patient had no changes. All the patients got fusion of bone graft and no internal fixation loosening and fractures occurred.

CONCLUSION360 degree circular decompression and transpedicle screw fixation can resect different types of thoracic longitudinal ligament ossification, and can achieve a good clinical effect.
