AIM:To explore and compare effect of coaxial micro-incision phacoemulsification and standard coaxial phacoemulsification in the treatment of cataract.
METHODS:A total of 88 patients(88 eyes) with senile cataract who underwent selective cataract ultrasonic emulsification resorption combined with intraocular lens implantation in the hospital from Aug. 2013 and Aug. 2015 were selected, they were divided randomly into the control group ( 44 cases, 38 cases completed, 6 cases dropped out ) and the observation group ( 44 cases, 40 cases completed, 4 cases dropped out ) . The control group received standard coaxial 3. 0mm small incision phacoemulsification, the observation group received coaxial 1. 8mm micro-incision phacoemulsification. All patients were combined with intraocular lens implantation. Intraoperative effective ultrasonic time, cumulative release energy, best corrected visual acuity before and after surgery in the two groups were recorded, corneal endothelium cell population, incision corneal thickness, percentage of cornea hexagon cell, corneal astigmatism changes before the operation, 1d, 7d, 30d after the operation were compared.
RESULTS: There was no significant difference in intraoperative effective ultrasonic time, cumulative release energy in the two groups(P>0. 05). There was no significant difference in postoperative best corrected visual acuity between the two groups(P>0. 05). Corneal endothelium cell population, percentage of cornea hexagon cell 1d, 7d, 30d after the operation in the two groups were significantly decreased compared with those before the treatment ( P < 0. 05 ), but there was no significant difference in the two groups ( P > 0. 05 ). Incision corneal thickness 30d after the operation in the observation group was significantly lower than the control group(P<0. 05). Degree of corneal astigmatism in the observation group 1d, 7d, and 30d after the operation were significantly lower than the control group (P<0. 05).
CONCLUSION: Coaxial micro - incision phacoemulsification and standard coaxial phacoemulsification can improve visual acuity of cataract patients, but the former can reduce degree of corneal astigmatism.

Objective:To evaluate the practical application of intra-abdominal pressure (IAP) monitoring product in patients receiving enteral nutrition (EN) and with high risk of intra-abdominal hypertension/abdominal compartment syndrome (IAH/ACS).Methods:Patients receiving EN treatment from Changzheng hospital were randomly divided as experimental group (measuring IAP with pressure monitoring product,n =60) and control group (measuring IAP with conventional method,n =60).The clinical data of gastrointestinal complications,gastric residual volume,IAP and completion of target infusions were collected and analyzed.Results:The incidence of gastrointestinal complications in experimental group patients significantly decreased comparing with the control group patients (7.92％ vs 28.33％,P ＜ 0.01).The levels of gastric residual volume and IAP in experimental group patients were lower than those in control group patients[(50.12 ± 10.66) ml vs.(101.54 ± 25.81) ml,(7.17 ± 1.84) cmH2O vs (12.36 ± 2.51) cmH2O,P ＜0.05].Moreover,The experimental group patients had a shorter period to achieve target infusions and higher proportion of completion treatments [88.3％ vs 71.7％,(2.94 ± 0.78)d vs (3.78 ± 1.02)d,P ＜ 0.05)].Conclusion:As utilizing pressure monitoring products to assist EN treatment for patients with high risk of IAH/ACS could achieve lower incidence of gastrointestinal complications,excellent EN tolerance,and improve target feeding,its clinical application should be extended.

Objective To analyze the characteristics,risk and induced factors of intussusception in Peutz-Jeghers syndrome (PJS).Methods From March 2nd 2005 to May 25th 2013,a total of 130 patients with PJS were selected.The clinical data of patients were collected,which included gender,age,the diagnostic age of PJS,family history,the diagnostic age of intussusception,clinical features,location,treatment and the maximum diameter of polyps which caused intussusception.Kaplan-Meier was performed to analyze the cumulative risk of intussusception.Results Among 130 patients with PJS,90 cases had intussusception.The age when first time diagnosed was from four to 33,median age was 16.The cumulative risks of intussusception at 10,15,20,25 and 30 years were 12.308％ (16/130),31.538％(41/130),51.538％(67/130),64.615％(84/130) and 66.923％(87/130).There was no significant difference in the cumulative risk of intussusception between male and female; with family history and no family history (both P＞0.05).A total of 131 intussusception happened in 90 patients,of which diagnosed by surgery,imaging examination and history reviewer was 125,four and two times,respectively.The initial symptom of 111 times of intussusception was acute abdomen and 15 were abdominal pain and vomiting.The left five intussusception was found by regular:examination.One hundred and fifteen intussusception was in small intestine and 16 in colon.There was 127,three and one time treated with surgery,conservative treatment,endoscopic therapy (dual airbags intestinal endoscopic polypectomy),respectively.The maximum diameter of polyps which caused intussusception was from 15 to 70 mm,average 40 mm.Conclusions Intussusception of patients with PJS is at young age and with a high cumulative risk.Intussusception is generally caused by diameter over 15 mm polyps.

Objective To study the MR features and differential diagnosis of oligodendroglioma.Methods Clinical and MR data of 34 pathology-diagnosed oligodendroglioma cases were analyzed retrospectively, which included tumor location,signal,size,enhanced and MRS features.Results 22 cases were diagnosed as WHOⅡoligodendroglioma and 12 cases WHOⅢ anaplastic oligodendroglioma.22 tumors located in the frontal lobes,4 tumors in the temporal lobes, 7 tumors in both frontal and temporal lobes,1 tumor located at the optic chiasma.25 tumors located in the superficial areas of the brain.For anaplastic oligodendrogliomas,tumor necrosis and cystic degenerations were showed in 11 cases,and hemorrhage or calcification in 6 cases.For oligodendroglioma,tumor necrosis and cystic degenerations were showed in 6 cases,hemorrhage in 2 cases,calcification in 8 cases.The average tumor diameter was 35 mm for oligodendroglioma and 58 mm for anaplastic oligodendroglioma.For anaplastic oligodendroglioma,obvious irregular or ring enhancements were showed in 11 cases.For oligodendroglioma, mild enhancement was showed in 6 cases,no enhancement in 6 cases and mild or moderate irregular ring-type enhancements in 4 cases.MRS was performed in 6 anaplastic oligodendrogliomas the Cho/Cr ratio was over 4 in 5 cases.MRS was performed in 12 oligodendrogliomas the Cho/Cr ratio was between 2.3 to 3.3 in 10 cases and below 2 in 2 cases.Conclusion The main MR feature of anaplastic oligodendroglioma is that tumor is located in the frontal lobe and superficial area of the brainwith irregular or ring-type enhancement,and the Cho/Cr ratio over 4.

ObjectiveTo observe the inhibitory and pro-apoptotic effects of two poly(ADP-ribose) polymerase (PARP-1) inhibitors, AG-014699 and AZD2281, on human hepatoma HepG2 cells and preliminarily explore the mechanism by which AG-014699 induces HepG2 cell apoptosis, and to provide a new therapeutic target for hepatoma. MethodsThe effects of different concentrations of AG-014699 and AZD2281 on HepG2 cell proliferation were determined by MTT assay. The cell apoptosis rate was measured by flow cytometry. The expression levels of caspase-3 and caspase-8 were measured by Western Blot. Inter-group comparison was made by t test. ResultsBoth AG-014699 and AZD2281 suppressed HepG2 cell proliferation in a time- and dose-dependent manner. However, the sensitivity of HepG2 cells to the two PARP-1 inhibitors was different. The half-maximal inhibitory concentrations of AG-014699 and AZD2281 at 48 h determined by MTT assay were about 20 μmol/L and 400 μmol/L, respectively. Flow cytometry and Western blot were not used to evaluate the apoptosis of HepG2 cells exposed to AZD2281 to which these cells were not sensitive. HepG2 cell apoptosis could be induced by 10, 30, and 50 μmol/L AG-014699, and the highest apoptosis rate at 48 h was significantly higher than that of the control group (3100%±2.13% vs 09%±0013%, P＜0.01). Compared with those in the control group, the protein levels of caspase-3 and caspase-8 in HepG2 cells after 48-h exposure to 30, and 50 μmol/L AG-014699 increased. ConclusionThe two PARP-1 inhibitors AG-014699 and AZD2281 can inhibit the proliferation of HepG2 cells, which showed different sensitivities to the two inhibitors. AG-014699 can induce HepG2 cell apoptosis by up-regulating the protein expression of caspase-3 and caspase-8.
