Journal of Chongqing Medical University 1987;0(01):-
Twenty two patients with variant types of absolute glaucoma were treated by surface cyc-lodiathermy. Follow-up time averages 3.5 years, without medication, intra-ocular pressure (IOP) was well controlled in 13 patients; IOP was decreased by 50% and the symptoms were relieved in two patients. The effective rate was 68%. In this paper, the technique and comp-lication of this operation were introduced. The technique rather simple. The effect of the operation is satisfactory, and complication is few. Therefore, we adopt cyclodiatharmy is a better procedure for absolute glaucoma

BACKGROUND:We have successfuly prepared digital coraline hydroxyapatite artificial bone scaffold in previous experiments, and it has been confirmed that it has the necessary physical and chemical properties of bone tissue engineering scaffolds. OBJECTIVE: To evaluate the sensitization of digital coraline hydroxyapatite artificial bone scaffold. METHODS:A total of 32 guinea pigs were randomly divided into saline group (negative control group, n=8), 5% formaldehyde group (positive control group,n=8), experimental A group (the mass ratio of 3:1,n=8), and experimental B group (the mass ratio of 4:1,n=8). Sensitization test at the maximal dosage was performed according toBiological Evaluation of Medical Devices-Part 10: Tests for Irritation and Delayed-Type Hypersensitivity, including intracutaneous induction, local induction, and provocation. Patch was removed after 24 and 48 hours, and the skin response was classified according to Magnusson and Kligman criteria. Patch was removed after 48 hours, and the skin was performed with biopsy, stained with hematoxylin-eosin, and observed under optical microscope. RESULTS AND CONCLUSION: Sensitization response was not tested in the negative control group, experimental A group and experimental B group at 24 and 48 hours after patch removal; however, moderate erythema was observed in the positive control group. Optical microscope demonstrated that spongiosis, edema, diffuse or perivascular mononuclear infiltration was not observed, and only a smal number of basicytes were seen in the experimental A and B groups. These findings indicate that the digital coral hydroxyapatite artificial bone scaffolds, with the mass ratio of 3:1 and 4:1, are biologicaly safe for sensitization.

Objective To observe the effect of Wnt/β-catenin pathway on proliferation of human umbilical vein endothelial cell (HUVEC) using the glycogen synthase kinase 3β (GSK-3β)-targeting RNAi recombinant adenovirus vector. Methods Homologous recombination and cloning techniques were used to construct RNAi recombinant adenoviral expressive vectors specific to GSK-3β. Then, the adenovirus plasmids was transfected into HEK 293A cells to produce adenovirus and amplify the adenoviral stock. Plaque forming assay was used to titer the adenoviral stock. The GSK-3β and β-catenin protein expressions were detected by Western blot and immunohistochemistry. The proliferation of HUVEC was detected with MTr assay. Results The RNAi adenovirus vectors specific to GSK-3β were successfully produced with high titer. The expression of GSK-3β protein in HUVEC could be down-regulated efficiently by the RNAi adenovirus, along with increased β-catenin protein expression. The proliferation of HUVEC was significantly increased (P < 0.05 or P < 0.01) after infected with GSK-3β RNAi recombinant adenovirus for 3, 5, 7 days. Conclusion RNAi adenovirus is an important tool that can inhibit the expression of GSK-3β efficiently, along with increased β-catenin protein expression. Up-regulating of the Wnt/β-catenin pathway might play an important role in the proliferation of HUVEC.

OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.
METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.
RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).
CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

OBJECTIVETo explore the clinical effects of PLIF surgery for elderly patients with lumbar degenerative disease.
METHODSFrom March 2010 to May 2013, 28 patients with lumbar degenerative disease, aged more than 80 years were treated with PLIF surgery. There were 10 males and 18 females, aged from 80 to 93 years old with an average of (85.44±3.66) years. Course of disease was from 3 to 20 years. The operation time, intra-operative blood loss, operation complications were recorded and JOA scores and Macnab criteria were used to evaluate the clinical outcomes.
RESULTSAll patients were followed up from 12 to 40 months with an average of 26.5 months. The average operation time was (150.00±26.42) min and the average intra-operative blood loss was (373.33±99.88) ml. The pre-operative JOA score was 12.30±2.43, and the corresponding postoperative JOA score at the final follow-up was 24.81±2.09 which was much higher than the preoperative one (P<0.01). According to the modified Macnab criteria to evaluate at the final follow-up, 16 patients got an excellent result, 10 good, 2 fair. In the weeks postoperatively, injuries of nerve root happened in 3 cases, superficial wound infection with delayed healing in 3 cases, and tear of the dural sac accompanied with cerebrospinal fluid leakage in 1 case. After long term follow-up, adjacent segment degeneration and the corresponding spinal canal stenosis occurred in 1 case at 34 months after operation. All cases got successful fusion without any displacement of internal fixation and pseudoarthrosis formation.
CONCLUSIONWith proper cases, fully preoperative preparation, perfect intra-operative manipulation and active treatment after operation, even advanced ages older than 80 years with lumbar degenerative disease could get satisfactory outcomes after PLIF surgery.
