Objective To observe curative effect of the rat nerve growth factor (NGF) treatment on anterior ischemic op?tic neuropathy(AION). Methods Patients with AION (n=78) were randomly divided into mouse NGF treatment group (treatment group):39 cases (39 eyes) and conventional treatment group (control group):37 cases (37 eyes). Patients in control group were given Actovegin 1.2 g intravenously, once a day while patients in treatment group were given 18μg mouse NGF once a day. Milton insurable were given orally at 0.5 mg, 3 times per day at both groups. Dexamethasone of 3 mg were given retrobulbarly once a day upon onset of symptoms and the extend of edema for 3 to 5 days. Rat nerve growth factor were given for consecutive14 days as a period of treatment, and the curative effect was observed after 28 days of treatment. Results In the treatment group:treatments were obviously effective in 28 eyes (71.79%), effective in 7 eyes (17.95%) and ineffective in 4 eyes (10.26%), so the total effective rate was 89.74%; In control group: treatments were obviously effective in 11 eyes (29.73%), effective in 15 eyes (40.54%) and ineffective in 11 eyes (29.73%), so the total effective rate was 70.27%. Curative effects in these 2 groups were of statistical significance (Z=3.552, P<0.05). Vision acuity and average light sensitivity in vi?sual field are better in treatment group than those control group (P<0.05). Conclusion Mouse NGF is effective in the treat?ment of AION and can improve vision acuity and visual field, therefore is worth promoting.

Multiple myeloma (MM) is a hematological malignancy caused by the clonal expansion ofbone marrow plasmacytes.It accounts for 10 ％ of all hematological malignancies.The proteasome,an intracellular enzyme complex that degrades ubiquitin-tagged proteins to regulate protein levels within the cell,plays an important role in maintaining cellular homeostasis.Proteasome inhibitors proved to be significantly effective in the clinical treatment of MM.In recent years,the application of the proteasome inhibitor has led to increased survival rates in MM patients.Bortezomib is the first proteasome inhibitor that has been approved by the US Food and Drug Administration due to its ability to reversibly inhibit the 26 s proteasome functions.Despite the fact that Bortezomib improves medical treatment,many patients experience difficulty responding to this drug and some patients who do respond eventually relapse.These results have led researchers to investigate new proteasome inhibitors with mechanisms different from those of Bortezomib.Some drugs that bind to the active site of the proteasome and irreversibly inhibit the complex have recently been developed and are currently being tested in advanced clinical trials.Here,we will elaborate on the proteasome inhibitors targeting MM and focus on newly discovered inhibitors that may overcome the resistance to Bortezomib.

.This study is to investigate the analgesic effect produced by intrathecal injection (ith) of oxysophoridine (OSR) and the mechanism of GABAA receptor. Warm water tail-flick test was used to detect the analgesic effect of OSR (12.5, 6.25, and 3.13 mg.kg-1 ith) and to observe the influence of GABA (gamma aminobutyric acid) agonist or antagonist on the analgesic effect of OSR in mice. Immunohistochemistry method were used to detect the influence of OSR (12.5 mg.kg-1, ith) on the GABAARalpha1 protein expression in spinal cord. The results obtained covers that OSR (12.5 and 6.25 mg.kg-, ith) alleviates pain significantly with the warm water tail-flick test (P<0.05, P<0.01), the rate of pain threshold increases by 68.45%; GABA and muscimol (MUS) produces analgesic synergism together with the OSR, picrotoxin (PTX) and bicuculline (BIC) antagonize the analgesic effect of OSR; OSR (12.5 mg.kg-1, ith) significantly increase the positive number of GABAARalpha1 nerve cell in spinal cord (P<0.01) and significantly decrease the average grey levels (P<0.01). In conclusion, OSR intrathecal injection has significant analgesic effect. And GABAA receptor in spinal cord is involved in the analgesic mechanism.

AIM:To observe and compare clinical effects of coaxial 1. 8mm microincision phacoemulsification and 3. 2mm small incision phacoemulsification.
●METHODS:A total of 117 eyes of 85 patients with age-related cataract in our hospital were divided randomly into two groups:43 patients (59 eyes) in the coaxial 1. 8 mm microincision cataract surgery group ( C - MlCS ) , 42 patients (58 eyes) in the coaxial 3. 2 mm traditional small incision cataract surgery group (C-SlCS). A total of 117 eyes were received phacoemulsification with intraocular lens implantation. Uncorrected visual acuity was recorded preoperatively and postoperatively at 1, 7, 30 and 90d. The effective phacoemulsification time and average ultrasound energy were recorded in surgery. Corneal endothelial cell and corneal topography were recorded preoperatively and postoperatively at 90 d.
●RESULTS:Uncorrected visual acuity ( logMAR) was no overall statistical significance difference between C-MlCS group and C-SlCS group (P>0. 05), but was significant statistical difference in different time-point within both groups(P<0. 05). Uncorrected visual acuity in different time-point had nothing to do with corneal wound size in cataract surgery(P>0. 05). On the 1 day after surgery, uncorrected visual acuity was 0. 16±0. 11 in C-MlCS group and 0. 22±0. 18 in C-SlCS group(P<0. 05). AVE was (7. 00± 2.72)% in C-MlCS group and (6. 16±3. 16)% in C-SlCS group (P>0. 05). EPT was (3. 09±1. 61)s in C-MlCS group and (3. 20±1. 92)s in C-SlCS group (P>0. 05). At 90 d after surgery, corneal endothelial cell loss percentage was (5. 81±2. 28)% in C-MlCS group and (5. 69±2. 38)% in C-SlCS group (P>0.05), SlA was (0.35±0.11) Din C-MlCS group and (0. 61±0. 13) D in C-SlCS group (P<0. 05).
● CONCLUSION: Compared with coaxial 3. 2mm traditional small incision cataract surgery, 1. 8mm coaxial microincision cataract surgery can get earlier visual rehabilitation and significantly reduce SlA. The coaxial 1. 8mm microincision cataract surgery is safe, effective and deserves further clinical applications.

Objective To investigate the relationship between the liver pain and the short-term curative effect in patients with primary hepatocellular carcinoma(HCC)after transcatheter arterial chemoembolization(TACE).Methods According to the degree of liver pain,118 HCC patients after the initial TACE treatment were divided into two groups:group A(with no complaint of serious liver pain)and group B (complaining of severe liver pain).Short-term curative effects at the fourth and sixth week after initial TACE were compared between the two groups,and the factors related to the liver pain after TACE were analyzed.Results Four to six weeks after the initial TACE,CT scan was performed in all patients.Based on the RECIST criteria the short-term curative effects were evaluated.The CR,PR,SD,PD of group A and B were 0%.1.45%.88.41%,10.14%and 0%,14.29%.81.63%,4.08%,respectively.The difference in OR(CR +PR)between two groups was statistically significant(P=0.0087).The postoperative liver pain was probably related to the preoperative tumor blood supply pattern,the tumor capsule.the cirrhosis and the type of iodized oil deposit.The type of iodized oil deposit showed a negative correlation with the grade of liver pain (r=-0.539,P＜0.001).Conclusion The liver pain occurred after TACE is a useful suggestive sign,which indicates that a good curative result will be obtained.It is of clinical significance to make a full understanding of the relationship between the liver pain and the therapeutic effect.

Objective To explore the role of kidney interstitial dendritic cells in irnmunodissonance moechanism in mice with multiple organ dysfunction syndrome(MODS).Method The model of MODS wasmade by injecting zymosan into the peritoneal caiecty of C57BL/6 miee,and the mice were randomly divided into 5 groups,namely,normal,3～6 hours,12～48 hours,5～7 days,10～12 days after administrating zymosan. Pathological changes of kidney interstitial dendritic cells were observed by transmission electronic microscopes. Specific sudaee markers CD205,CD11e,CDSO,MHCⅡmolecules I-A~b,CD4~+ and CD8~+T lymphocyte subgroups in peripheral blood were detected by immunohistochemistry and flow cytomctry.Results In acute injury stage,in comparison with normal group,interstitial dendritic cells had a continuous proliferation with high expression of CD80 and I-A~b(P

Objective To evaluate the effect of docosahexaenoic acid (DHA) on hepatic ischemia-reperfusion (I/R) injury in rats.Methods Fifteen male Sprague-Dawley rats, aged 8-10 weeks, weighing 250-300 g, were randomly divided into 3 groups (n =5 each) using a random number table: sham operation group (group S), hepatic I/R group (group I/R) , and group DHA.Hepatic I/R was induced by clamping the hepatic pedicle supplying the left and middle lobes of the liver for 60 min, followed by 24 h reperfusion in anesthetized rats.DHA 4 mg/kg was injected intravenously at 30 min before ischemia and 10 min of reperfusion in group DHA.The equal volume of solvent was given instead in S and I/R groups.Blood samples were taken from the inferior vena cava at 24 h of reperfusion for determination of serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) activities, and resolvin D1 concentrations.The rats were then sacrificed, and the livers were removed for determination of myeloperoxidase (MPO) activity (by spectrophotometry), and interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) mRNA expression (by quantitative real-time reverse transcriptase polymerase chain reaction).The livers were cut into sections which were stained with haematoxylin and eosin, and examined under light microscope.Results Compared to group S, the serum ALT and AST activities, serum resolvin D1 concentrations, and MPO activity, and IL-6 and TNF-α mRNA expression in liver tissues were significantly increased in I/R and DHA groups (P＜0.05).Compared to group Ⅰ/R, the serum resolvin 1D1 concentrations, and MPO activity and TNF-α mRNA expression in liver tissues were significantly decreased (P＜0.05) , and no significant difference was found in the serum ALT and AST activities in group DHA (P＞0.05).There was no significant difference in pathological changes of the liver between group DHA and group I/R.Conclusion DHA can attenuate inflammatory responses during hepatic I/R, but it is not sufficient to mitigate liver injury in rats.

Objective:To explore CCR7 expression in splenic dendritic cells and its role in migration and activity of splenic dendritic cells in multiple organ dysfunction syndrome (MODS) in mice.Methods:The MODS model of mice was reproduced by Zymosan injection into peritoneal cavity.The mice were randomly divided into groups of normal,3-6 hours,24-48 hours and 10-12 days post zymosan injection.CD11c and CD205 were analysed by immunohistochemistry;The expression of CD86 and CCR7 of DCs were studied by the flow cytometry analysis.Results:In normal mice,many DC were found at the margin between the red and white pulp.In the 3-6 h and 24-48 h groups,CD86 and CCR7 were strongly up-regulated in the DC,and they distributed in T cells areas.In the 10-12 d group,DC distributed at the margin by the immature form.Conclusion:The CCR7 expression level of DC has close correlations with the migration of DC,CCR7 can be used to evaluate the migration and functional activity of DC in MODS.
