AIM: To report a case of late onset diffuse lamellar keratitis (DLK) after laser in situ keratomileusis(LASIK) in 11 months due to corneal trauma. ·METHODS: A 22-year-old female patient underwent uneventful bilateral LASIK using a laserSight SLX excimer laser and Moria II microkeratome. No complications were observed during the operation and the early postoperative period.·RESULTS: 11 months after LASIK, grade I DLK was diagnosed after the book paper hurt the right corneal epithelium. The DLK responded rapidly to topical corticosteroid therapy, and healed in 2 weeks without complication. ·CONCLUSION: Although DLK Wpically develops in the early postoperative period, it could occur months after surgery. Treatment should begin as soon as DLK is diagnosed.

The compound that distributes in the herbs with one common effect was named as "co-effect compound" (CEC). The CECs of three traditional Chinese medicine(TCM) effects, purgative, relieving pain and clearing heat, had been found and studied. A strong corresponding relationship was found between the pharmacological activities of CECs and the TCM effect they belong to. The study shows that it may be a feasible method to connect traditional effect of TCM with modem pharmacological activity.

OBJECTIVETo evaluate the early clinical and radiographic outcome of scaphoid non-unions treated with Acutrak headless compression screw.

METHODSFrom January 2008 to July 2011,21 patients with scaphoid non-union were treated in our department. There were 18 males and 3 females with a mean age of (23.6 +/- 4.6) years; 12 cases were on right hand and 9 were on left. According to Herbert-Fisher classification, there were 10 cases with type D1, 7 cases with type D2, 3 cases with type D3, and 1 case with type D4. The mean time from injury to operation was (12.4 +/- 2.7) months. All patients were treated with Acutrak headless compression screw fixation (6 cases received 2 screws fixation, 15 cases received 1 screw fixation, and Matti-Russe bone grafting was applied in 7 cases). The carpal height, the scaphoid index and changes of the scapholunate angle were assessed before and after the operation. Range of motion and grip strength were recorded and the wrist function was assessed according to the Patient-Rated Wrist Evaluation (PRWE).

RESULTSAverage duration of follow-up was (21.3 +/- 3.6) months. All the patients attained radiological union in a mean time of (13.3 +/- 2.4) weeks following the operation. No obvious complications were recorded. The surgical treatment allowed the preoperative mean scaphoid index of 0.61 +/- 0.13 and the preoperative mean scapholunate angle of (59.4 +/- 6.8) degree to be improved to 0.69 +/- 0.10 and (44.3 +/- 8.2)degree postoperatively, respectively. There was a substantial improvement in grip strength and pain amelioration after surgery. The preoperative mean PRWE score of 45.2 +/- 4.7 was improved to 76.1 +/- 5.2 postoperatively. All patients returned back to the original work,the average time from surgery to work was (6.0 +/- 1.1) months.

CONCLUSIONFor scaphoid non-unions, Acutrak headless compression screw fixation can provide anatomical reduction, provide satisfactory results with a high union rate, well return of function and minimal complications in the early stage.

OBJECTIVETo observe the effects of acupuncture at "Tianshu" (ST 25) on electro-activity and mechanical motility at different phases of migrating motor complex (MMC) during jejunal digestion period in rats with detached jejunum, so as to explore the effect and mechanism of acupuncture on regulating intestinal movement.

METHODSSixteen adult SD rats were selected. Electrodes were implanted in the serous membrane of intestinal smooth muscl.e and high-sensitivity sensors of strain gauge were sutured on serosal surface, and then the rat was anesthetized and its jejunum was detached. Electro-acriviry and mechanical motility of jejunal smooth muscle were recorded simultaneously. Acupuncture was applied at "Tianshu" (ST 25) at MMC I , MMCII and MMC III, respectively, to observe its influence on electro-activity and mechanical motility.

RESULTSAt phase of MMC I, there was no obvious change of the fast wave before and after the acupuncture, while the frequency and amplitude of slow wave and mechanical motility were both significantly decreased compared with baseline (P < 0.01). At MMCII-Ill, the frequency and amplitude of fast wave, slow wave and motility were all significantly decreased compared with baseline (P < 0.01). Acupuncture at "Tianshu" (ST 25) had prohibited effects on electro-activity and mechanical motility of jejunal smooth muscle in rats with detached jejunum.

CONCLUSIONAcupuncture at "Tianshu" (ST 25) has obvious prohibited effects on electro-acrivity and mechanical motility at MMC I , MMC II and MMC III time phases in rats with detached jejunum. The possible mechanism is that acupuncture at "Tianshu" (ST 25) could prohibit jejunum movement through reflex path of skin-sympathetic.

Objective To define the stages of medical rescue after earthquake or tsunami disaster and their significance.Method Three stages of medical rescue were defined according to the clinical features of diseases in 3-37 days after earthquake or tsunami in Pakistan and Indonesia.The classification of diseases was based on the criteria of disaster medical rescue set by World Health Organization.Five diseases including injuries/wounds,acute upper respiratory tract infection,acute hemorrhagic enterocolitis,acute enterecolitis and other diseases of internal medicine except epidemic or suspected epidemic diseases were employed to define the stages of disaster medical rescue.Results Injuries/wounds mainly occurred in 6 days after disaster.The incidences were 61.45% to 79.52% and 61.48% to 72.35% in Pakistan and Indonesia,respectively.The incidence of acute upper respiratory tract infection reached to a considerably high rate one week after disaster.Other diseases usually appeared one week later with incidence of 33.93% to 71.11% and 31.50% to 52.11% in Pakistan and Indonesia,respectively.The rate of acute hemorrhagic enterocolitis was 2%o in Indonesia whereas 35‰of acute enterocolitis was found in Pakistan.Conclusion Three stages of disaster medical rescue could be well defined.(1)Early or critical stage(in 6 days after disaster):Treatment of injuries/wound and resuscitation was the primary step to deal with.(2)Intermediate of subaeute stage(7-30days following disaster):The incidences of various kinds of diseases increased and more medical resources were needed in order to treat the upper respiratory tract infection and to lower the disable rate,and to prevent the prevalence of epidemic diseases.(3)Later or recovery stage(1-3months after disaster):The general condition of victims became even better than that of those affected by commonly occurred local diseases,and during this period,there were shortages of medical facilities and medical personnel.Therefore,supplement of medical resources was required.The well defined stages of medical rescue have an important significance for medical rescue teams to treat victims and prevent epidemic diseases more efficiently and timely,and also provide a guidance of scientific basis for the logistics officers of local government as well as our government to make a proper and reasonable distribution of medical resources,and dispatch and arrangement of medical rescue teams.This guidance also helps to make victims re- reliant.

0.05).Conclusions The reduced expression of HLA-G on placenta in ICP patients may alter the maternal-fetal immune response and thus be involved in the pathogenesis of this disorder. Dexamethasone can upregulate the expression of HLA-G on placenta.The 14 bp deletion polymorphism in exon 8 of HLA-G gene might not have a significant influence on the development of ICP.
