AIM: To study the clinical characteristics of corneal perforation ( CP) .
METHODS:A retrospective analysis in July 1995 to July 2010 the First Affiliated Hospital of Fujian Medical University diagnosed CP 72 patients ( 72 eyes ) , clinical characteristics of all the patients were analyzed.
RESULTS: The incidence of corneal ulcer perforation rised year by year, the morbidity of male and female was 17:7, the onset age focused on 48 years old. Of 23 industrial workers ( 32%) with clear history of trauma, pathogeny identification results:top two:fungal infection and Acanthamoeba keratitis. A using history of glucocorticoid was found in 10 cases.
CONCLUSION:There are plenty of primary causes of CP such as traumas, fungal infection, Acanthamoeba keratitis, eroded keratitis, etc. CP happens in middle-aged males in Fujian province, most traumas are the causes, the main pathogenic bacteria is fungal infection.

Objective To investigate the effect of comprehensive intervention therapy of losing weight on leptin and blood lipid,blood glucose,insulin in adolescent girl students with simple obesity.Methods Simple obesity adolescent girl students were accepted the losing weight therapy composed of the aerobic exercise,reasonable diet,behavior modification and medical supervision for 10 months.Then the changes of blood leptin and correlated hormone were examined before test,during test and after test,respectively.Results The leptin and correlated hormone levels were significantly higher in obesity subjects than that in normal subjects,and the levels of serum leptin was positively correlated with BMI and insulin.The blood leptin and blood lipid,blood glucose,insulin were decreased obviously after experimental losing weight.Conclusion Comprehensive intervention therapy of losing weight can significantly lose weight,leptin and insulin,so it plays an important role in modifying the metabolism disorder

OBJECTIVERNA interference was applied to knockdown the Dhcr7 gene in mouse embryonic palatal shelves to facilitate understanding of the function of Dhcr7 gene variants in the fusion of palatal shelves.

METHODSThe pAdTrack-CMV-siDhcr7 was constructed using the specific siRNA sequence of Dhcr7 from C57BL/6J mouse. The pAdTrack-CMV- siDhcr7 of positive clones was reconstructed in vitro, and the recombinant adenovirus pAdEasy-1-siDhcr7 of kanamycin resistance was screened. The adenovirus vector DNA was then prepared for transfecting the embryonic palatal shelves. Thirty pairs of embryonic palatal shelves at 13.5 d gestational age were harvested and then randomly divided into the following three groups: normal control group (n = 10), which included palatal shelves inculture medium without cholesterol; blank adenovirus control group (n = 10), which included palatal shelves in culture medium without cholesterol and blank adenovirus; and experimental group (n = 10), which included palatal shelves in culture medium without cholesterol and adenovirus encoding Dhcr7 siRNA. At 48 h after in vitro cultivation, the mRNA and protein of the palatal shelves were obtained for scanning electron microscopy (SEM), reverse transcription polymerase chain reaction (RT-PCR), and Western blot analyses.

RESULTSSEM showed that the palatal shelves of the normal control and blank adenovirus control groups fused and formed continuous palates, whereas those of the experimental group was almost undeveloped but exhibited large gaps between the two palatal shelves. RT-PCR and Western blot analyses showed that the mRNA and protein of Dhcr7 in the experimental group decreased compared with those in the normal control group with a significant difference (P < 0.05).

CONCLUSIONResults indicate that Dhcr7 gene silencing affects the fusion of palatal shelves. Thus, Dhcr7 gene may serve a function in the normal development of palates.

Objective To evaluate the effect of dexmedetomidine on acute kidney injury after cardiac valve replacement with cardiopulmonary bypass (CPB).Methods One hundred patients of both sexes with rheumatic heart disease,aged 32-64 yr,weighing 46-75 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ (New York Heart Association class Ⅱ or Ⅲ),scheduled for elective cardiac valve replacement with CPB,were divided into 2 groups (n =50 each) using a random number table:control group (group C) and dexmedetomidine group (group D).Dexmedetomidine was intravenously infused in a loading dose of 1 μg/kg over 10 min before induction of anesthesia followed by an infusion of 0.4 μg · kg-1 · h-1 until 24 h after operation in group D,while the equal volume of normal saline was given in group C.The urine output per hour during the postoperative 48 h period was recorded.At 6,12,24,36 and 48 h after operation,blood samples were collected from the median cubital vein for determination of serum creatinine levels.The development and severity of acute kidney injury were determined according to the urine output and serum creatinine level.Results Compared with group C,the incidence and severity of acute kidney injury were significantly decreased in the postoperative 48 h period in group D (P＜0.05).Conclusion Dexmedetomidine infused in a loading dose of 1 μg/kg over 10 min before induction of anesthesia followed by an infusion of 0.4 μg · kg-1 · h-1 until 24 h after operation can reduce the development and severity of acute kidney injury after cardiac valve replacement with CPB in patients.

Objective: To seek the optimal acupuncture time for primary dysmenorrhea and provide clinical basis for optimal acupuncture treatment protocol. Methods:A total of 90 eligible cases were randomly allocated into three groups, 30 cases in each group. Points Guanyuan (CV 4), bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for patients in all three groups, with a different treatment duration: 15 min in group A, 30 min in group B and 45 min in group C. Then the clinical efficacy in each group was evaluated by pain symptom scoring. Results:As for the pain symptom scores, there were statistically significant intra-group differences between before and after treatment in three groups (allP<0.05); coupled with statistically significant inter-group differences between group B and the other two groups (bothP<0.05). As for clinical efficacy, there were statistical differences between group B and the other two groups (bothP<0.05), indicating that 30 min of acupuncture is the optimal duration in the treatment of dysmenorrhea. Conclusion:With the same needling manipulation, 30 min of acupuncture treatment achieves a better efficacy for primary dysmenorrhea.

Objective In order to offer a noninvasive and objective examination method for assessing the clinical diagnosis and eurative criterion of concussion patients, the patients color three - dimensional transcranial doppler( 3D - TCD) characteristic at deferent phases, parameter and clincal manifestation were studied Method Parameter of Median Cerebral Artery(MCA), Base Artery(BA), the average peak forwand velocity of cerebral blood flow, train figure were tested by 3D - TCD within 24 hours, 3 - 6 days and at the end of treatment, respectively. The results were compared with clinical diagnoses and curative criterion.
