● AIM: To explore the role that hepatocyte growth factor plays in proliferative vitreoretinopathy (PVR) after retinal detachment.● METHODS: The contents of hepatocyte growth factor in subretinal fluid (SRF) in 49 cases with retinal detachment were measured with enzyme-linked immunosorbent assay.● RESULTS: With the worsening of PVR and vitreous opacity and prolonging of disease course, the content of hepatocyte growth factor increased (P＜0.05), the difference being statistically significant.● CONCLUSION: The change of hepatocyte growth factor in SRF had a close relation ship with the occurrence and development of PVR after retinal detachment.

group Nor(P0.05).Conclusions The changes of ambulatory pulse pressure can reflect the degree of EH.The obvious increase of PP and decrease of DBP maybe are the exclusive features of ABPM in EH patients with target organs damage.

The plastic splint PCL,which is introduced in this article,is a new type of medical exter- nal immobilization material.During the course of its development,the burden has been optimality seeked with regressive orthogonality after screening of the material.Its function has attained the international levels during the eighties.This splint may be used not only in the treatment of burns and various orthopedic conditions,but also in the immobilization of fracture and rehabilation treatment of orthopedic patients etc.

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

Objective To investigate the relationship between the expression of MMP-7 in peripher- al blood and esophageal cancer.Methods By using Real time RT-PCR, blood samples from 82 cases with postoperative esophageal cancer were detected.Results 37.8 %(32/82)patients were positive for MMP-7 mRNA expression.MMP-7 mRNA positivity significantly correlated with lymph node metastasis,stage,and hematogeneous metastasis.Recurrent disease was found in 28 of 82 cases. Of 28 patients experiencing re- lapse,15 patients were serially follow-up in every three months.The number positive of MMP-7 mRNA be- fore detection by imaging,at the same time of detection by imaging,and after detection by imaging was 5 cas- es,8 cases and 2 cases respectively.Conclusion Examination of MMP-7 mRNA in peripheral blood during follow-up is useful for early detection of occult recurrence.

Objective To use estimation of physiologic ability and surgical stress (E-PASS) to assay operative risks in patients with hip fracture and to discuss its application value.Methods Sixtyfour patients with hip fractures were subjected to the retrospective review.There were 38 males and 26 females,at mean age of 54.3 years (range,19-84 years).The operative risk was assayed by E-PASS and postoperative complications as well as case fatality were detected and compared.Results Postoperative complications developed in 16 patients (25％).E-PASS score was significantly higher for the patients with postoperative complications than in those without [(0.64 ± 0.31) points vs (0.22 ± 0.31) points,P ＜ 0.05].Incidence of complications was significantly lower for patients with a E-PASS score ＜ 0.6 than for those with a E-PASS score ＞ 0.6 (19％ vs 50％,P ＜ 0.01).There were 2 deaths among 16 patients with a E-PASS score ＞ 0.6.The remaining 48 patients with a E-PASS score ＜ 0.6 obtained satisfactory recovery.Conclusion E-PASS is effective for predicting operative risk and is instructive for surgery decision in treatment of hip fractures.

AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

Objective To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on the recovery of gastrointestinal function after laparoscopic intestinal operation.Methods Sixty patients of the selective laparoscopic intestinal resection, 28 males and 32 females, aged 18-65 years, ASA physical status Ⅰ or Ⅱ, were enrolled and randomly allocated into two groups: TEAS group and control group, 30 in each group.Patients in TEAS group accepted transcutaneous electrical acupoint stimulation treatment at Neiguan, Hegu, Zusanli points from the time before induction of anesthesia to 3 days after surgery, and patients in the control group were treated with transcutaneous electrical acupoint stimulation, but the electrode pads were just attached on the related points with no electric stimulation.Plasma motilin concentrations preoperatively, postoperatively 12, 24, 48 and 72 h were measured in the two groups.The recovery time of intestinal peristalsis, anal flatus time, in-hospital time and the incidence of nausea and vomiting within 3 days after operation were observed.Results Compared with the control group, serum motilin concentration postoperative 24 h increased significantly [(218.5±52.3) pg/ml vs (141.8±45.8) pg/ml, P<0.05], the time of intestinal peristalsis recovery [(19.4±3.2) h vs (29.6±7.8) h, P<0.05] and flatus [(23.2±4.7) h vs (36.5±8.9) h, P<0.05] were shorter, the incidence of postoperative nausea and vomiting within 3 days after operation decreased significantly in TEAS group (16.7% vs 36.7%, P<0.05).There was no statistically significant difference of the in-hospital time between the two groups.Conclusion TEAS can promote the recovery of gastrointestinal function in patients undergoing laparoscopic intestinal surgery.
