OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.

METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.

RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).

CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

Objective To investigate the morphological changes, apoptosis and brain-derived neurotrophic factor mRNA(BDNF mRNA)expression in rat conus medullaris induced by cauda equine compression, and to discuss the possible mechanisms. Methods Ninety male SD rats were divided into 3 groups: normal control, sham operation,and cauda equine compressed. The animals were sacrificed and took samples in 30 min, 2 hours,4 hours,8 hours,1 day,3 days,1 week,2 weeks,3 weeks after cauda equine compression model were created. The morphological study concerned with cauda equina and conus medullaris was done under light microscope and transmission electron microscope. TUNEL staining and in situ hybridization staining were used to investigate apoptosis and BDNF mRNA expression changes. The positive cells in 1mm2 were calculated,and the data were disposed through one way analysis of variance. Results Histological observation showed notable alteration of cauda equina and neurons in conus medullaris. The positive cells of TUNEL and BDNF mRNA in situ hybridization staining increased in 8 hours and 4 hours after cauda equina compressed,and both reached the climax in 3days after cauda equina compressed. At the time 3weeks after cauda equine compressed, the positive cells were still much higher than that of the control groups. Conclusion The compression of cauda equina will result in neurons morphological changes and apoptosis in medullary cone,and cause central neuron un-reversible injury. It might be one of the reasons why the prognosis is poor in cauda equina syndrome. Neurons and glial cells may produce BDNF by themselves to survival from cauda equina compression.

AIM: To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). METHODS: Sixty-eight SLIMCE operation eyes were studied with slit-limp microscope, break- up time (BUT), SchirmmerⅠtest (SⅠt),and fluorescence(FL) to observe the alterations of tear film at different time points in postoperation. Impression cytology and microphoto-analyses technique were also applied to observe the goblet cells at different time points postoperation(7,14,30,60,90 days). RESULTS: Subjective complaint of dry eye within 90 days after the operations were significantly increased compare with preoperations(5-27,23,19,16,13; 2-16,14,8,6,3). The schirmmer Ⅰ test were greatly increased in 14 days postoperation(10.1±4.5;15.0±4.7,13.8±5.7),the mean scores of fluorescence increased (0-17,9,5;0-8,3,1) and the mean break-up time decreased in 30 days post-operation(10.3±2.2;5.5±2.3,7.0±2.4,7.9±2.2) (P<0.05). CONCLUSION: SLIMCE operation have effect on the stability of tear film.

Objective To investigate the relationship between the steroid-sensitive nephrotic syndrome(SSNS) and interleukin-18(IL-18) and to approach the inhibitive role of dexamethasone(DEX) on expression of IL-18 of peripheral blood mononuclear cells(PBMC) in children with SSNS in vitro.Methods IL-18 levels of serum, urine and supernatants of PBMC cultured in vitro were measured by enzyme linked immunosorbent assay(ELISA) in 23 children with SSNS who were either before or after treatment. Fifteen age-matched healthy children served as normal control group, and another 18 children with respiratory infections as infectious control group.Results There were signi-ficant differences of IL-18 in serum and urine before and after treatment in children with SSNS (t=15.072,16.149 Pa

ObjectiveTo observe the effect and safety of continuous epidural analgesia with sufentanil in different concentrations combined with 0.125% bupivacaine on pain after thoracotomy.Methods30 patients with ASA grade Ⅱ～Ⅲ and underwent thoracotomy were randomly divided into 3 groups treated with 0.125% bupivacaine combined with sufentanil 0.25 μg/ml (group A), 0.50 μg/ml (group B) and 0.75 μg/ml (group C) respectively. Before operation starting, epidural puncture was performed at T7～T8 and a catheter was put in. After operation, continuous epidural analgesia was performed by connecting the catheter and a analgesic pump. Analgesia effect was evaluated by visual analogous score (VAS) at sixth, twelfth, twenty-fourth and forty-eighth hours after operation. Dosage of assistant drug and side effects such as calmness, nausea, vomiting, skin pruritus and respiratory inhibition were also recorded.ResultsVAS scores and dosage of assistant drug of group B and group C were not different, but they were all lower than that of group A (P<0.05). Scores of skin pruritus of group A and group B were lower than that of group C (P<0.05), but there was no significant difference between group A and group B. No respiratory inhibition occurred in patients of all three groups.ConclusionContinuous epidural analgesia of 0.50 μg/ml sufentanil combined with 0.125% bupivacaine is safe and effective for patients after thoracotomy.

OBJECTIVETo measure the iodine nutritional status on adult islanders and to evaluate the advantages and disadvantages of iodized salt prophylactic programs.

METHODSA comparative study was carried out in 8 rural townships selected from Dinghai (iodized salt district) and Daishan (non-iodized salt district) of Zhoushan islands by random sampling method. Mann-Whitney test was used to compare the urinary iodine concentration and dietary iodine intake of the two groups. Spearman correlation test was used to look for the correlation of urinary iodine concentration and dietary iodine intake in the two groups respectively.

RESULTSThe amounts of daily iodine intake excluding the iodine intake from iodized salt in the two groups were 128 micro g and 147 micro g respectively but the difference was not statistically significant (u = 1.847, P = 0.065). The urinary iodine concentration of non-iodized salt group was 90 micro g/L, lower than 194 micro g/L in iodized salt group (u = 14.673, P = 0.000). There was no significant correlation between daily iodine intake and urinary iodine concentration (r(s) = 0.052, P = 0.095).

CONCLUSIONSIn Zhoushan islands, the daily iodine intake did not meet the daily need (150 micro g/day) suggesting that iodized salt supplement was necessary. However, side effect due to overdose should be brought into attention.

To study immunophenotype and cytotoxicity of the immunocytes in bone marrow and peripheral blood after activation by combined cytokines, mononuclear cells (MNC) of bone marrow and peripheral blood were activated by IFN-gamma, IL-1, IL-2 and McAb-CD3 in vitro. The cell amount and morphology during culture were observed. Cytochemical staining and immunophenotype analysis were done before and after culture in two groups of MNC. Cytotoxicity was tested by MTT method. The results showed that the cell number of two groups increased obviously in culture (P < 0.05), while the peripheral blood mononuclear cells increased more markedly (P < 0.05). The cytochemical staining showed POX decrease, but PAS increase in two groups. The positive ratios of CD3(+), CD56(+) and CD38(+) cells in two groups increased obviously after culture (P < 0.05), but there was no significant difference between those two groups. CD3(+) CD56(+) cells increased obviously in peripheral blood mononuclear cells activated by cytokines (P < 0.05), but CD3(+) CD56(+) cells did not increase in bone marrow mononuclear cells. There was no significant difference between two groups' cytotoxicity. It was concluded that IFN-gamma, IL-1, IL-2 and McAb-C D3 increased cell number and cytotoxicity of both bone marrow and peripheral blood mononuclear cells that can be used in cell immunotherapy.

OBJECTIVENephrotic syndrome (NS) is characterized by marked urinary excretion of albumin and other intermediated-size plasma proteins such as transferrin. The aim of this study was to determine the changes of serum iron and transferrin and the relationship between the serum and urinary transferrin.

METHODSThe indexes related to iron metabolism, including serum iron, ferritin, transferrin, total iron-binding capacity, transferrin saturation and hematological parameters (Hb, MCV, MCH), and urinary transferrin were measured in 37 children with NS before treatment and at the remission stage. Thirty-five age-matched healthy children served as controls.

RESULTSSerum iron levels (18.8 +/- 3.8 micromol/L) in NS patients before treatment were significantly lower than in the healthy controls (22.2 +/-3.8 micromol/L) and those measured at the remission stage (21.0 +/- 3.5 micromol/L) (P < 0.01). Serum transferrin levels in NS patients before therapy (1.9 +/- 0.3 g/L) also decreased compared with those in the healthy controls (3.1 +/- 0.5 g/L) and those measured at the remission stage (2.9 +/- 0.6 g/L) (P < 0.01). In contrast, serum total iron-binding capacity and transferrin saturation were noticeably higher in NS patients before treatment than those in the healthy controls (total iron-binding capacity 56.4 +/- 9.2 micromol/L vs 50.7 +/- 6.8 micromol, P < 0.01; transferrin saturation 55.7 +/- 9.2 % vs 46.4 +/- 8.2%, P < 0.01) and were also higher than those measured at the remission stage (51.9 +/-7.7 micromol/L and 47.4 +/- 13.3%) (P < 0.01). Serum transferrin positively correlated to serum albumin (r = 0.609, P < 0.01) and negatively correlated to urinary transferrin (r = -0.550, P < 0.01) in NS patients before treatment.

CONCLUSIONSSerum iron and transferrin levels markedly decreased in NS patients, which may be partially related to the urinary loss of transferrin.

Objective: To investigate the relationship between P27，P53 and PCNA expression in human gastric carcinoma tissues and clinicopathological parameters. Methods: The expression of P27，P53 and PCNA in 62 human gastric carcinoma tissues was examined with immunohistochemistry SP method. Results: Positive rates of P27，P53 and PCNA expression were 37.1％, 40.4%，83.9％. P27 expression was related with Bormann type, infiltrative depth, lymph node and distant metastasis and clinical stage. P53 expression was related with sex of patients, distant metastasis and clinical stage. PCNA expression was related with age of patients and infiltrative depth of tumor. P27 positive expression group was higher than negative group as to 5-year survival. P27 expression was in reverse relation with PCNA expression. Conclusion: The expression of P27, P53 and PCNA may be regarded as an important marker in judging malignant degree of gastric carcinoma,distant metastasis and prognosis.

Objective To observe the efficacy of electroacupuncture at Baihui (GV20) and Shenting (GV24) on learning and memo-ry in rats after cerebral ischemia-reperfusion, and explore the possible mechanism. Methods A total of 45 male Sprague-Dawley rats were randomly divided into sham group (n=15), ischemia group (n=15) and electroacupuncture group (n=15). The left middle cerebral arteries of the latter two groups were occluded with the modified Longa's method for two hours and reperfused, and the electroacupuncture group received elec-troacupuncture at Baihui and Shenting once a day for seven days, then. They were assessed with Longa's score one, three, five and seven days after intervention. They were tested with Morris water maze since four days after intervention, once a day for four days. The cerebral infarction volume was measured with TTC staining seven days after intervention, while the protein expression of Beclin-1 was detected with Western blotting. Results Longa's score improved in the electroacupuncture group compared with that in the ischemia group since three days after intervention (P<0.05). The escape latency decreased and the times cross the area of platform increased in the electroacupuncture group compared with that in the ischemia group at every point (P<0.05). The cerebral infarction volume reduced (F=7.651, P<0.001) and the expression of Beclin-1 decreased (P<0.05) in the elec-troacupuncture group compared with that in the ischemia group.Conclusion Electroacupuncture can improve learning and memory in rats after cerebral ischemia-reperfusion, which may relate with regulation of autophagy network.
