AIM: To explore the effect of early posterior approach vitrectomy in the treatment of penetrating ocular trauma with intraocular foreign body.METHODS: Totally 10 cases of penetrating ocular trauma with intraocular foreign bodies(IOFB) in the past two years were included.Emergency vitrectomy, intraocular foreign body removal and silicone oil tamponade were performed by the same surgeon.Antibiotics and steroids were given after surgeries.Retinal photocoagulation was done according to fundus conditions after surgeries.RESULTS: One patient combined with preoperation endophthalmitis and severely damaged retina failed to recover, eventually came to phthisis bulbi.Vitrectomy and IOFB removal were all successfully performed in the other patients.The postoperation follow-up time was 3-18mo.Two of the patients received secondary vitrectomy and silicone replacement surgeries due to recurrent retinal detachment.The remaining patients had no further bleeding with intraoclar pressure(IOP) 8-21mmHg.At the last follow-up, three of them gained best corrected visual acuity better than 0.1, two patients had visual acuity of 0.01 to 0.1 and four patients had poor visual acuity of light perception to FC/50cm because of macular damage.The patient with phthisis bulbi had no light perception.CONCLUSION: Early vitrectomy, foreign body removal and silicone oil tamponade is an effective treatment for patients with penetrating eyeball injury with IOFB.

Neonatal cerebral infarction is an area of damaged cerebral tissue resulting either from disruption to blood flow in a major cerebral artery from thrombosis or embolism or from thrombosis in a major cerebral vein.The pathogenesis is unknown at present,many studies have shown that genetic,mother hypertension,gestational diabetes,smoking,neonatal congenital heart disease,infections,meningitis are the risk factors of neonatal cerebral infarction.

[Objective]To investigate the significance of the high-risk human papilloma virus (HPV)detection in the screening and diagnosis of cervical lesions.[Methods] The high-risk HPV DNA test results of 797 patients with cervical lesions who all accepted cytology and histopathology test were collected and analyzed retrospectively.[Results]The high-risk HPV DNA positive rates in cervicitis,cervical intraepithelial neoplasia(CIN)Ⅰ,CIN Ⅱ,CIN Ⅲ and cervical cancer were 53.41％(188/352),70.91％(117/165),87.63％(85/97),97.90％(140/143),97.50％(39/40),respectively.The sensitivity and negative predictive value of the high-risk HPV DNA detection for CIN Ⅱ and more serious lesions were 96.66％(318/329),93.29％(153/164),respectively.The detection rate of CIN Ⅱ and more serious lesions in patients with atypical squamous cells of undetermined significance(ASCUS)and positive high-risk HPV DNA was 30.03％(94/313),while the rate in patients with negative high-risk HPV DNA was 1.55％(2/129).[Conclusions] The more serious the cervical lesion is,the higher high-risk HPV DNA positive rate is.It is most closely related with CIN 11 and cervical cancer.The high-risk HPV DNA detection has high sensitivity and negative predictive value for CIN Ⅱ and more serious lesions.The high-risk HPV DNA detection has high negative predictive value in CIN Ⅱ and more serious lesions in ASCUS.

Objective To detect the expression of triggering receptor expressed on myeloid cells-1 (TREM-1) in mice with acute necrotizing pancreatitis (ANP). Methods Male kunming mice (n = 50) were randomly divided to control group, ANP 24, 48, 72, 96 h group. ANP model was induced by intraperitoneally injection with 20% L-arginine at a dose of 4 mg/g each, 1 h apart. Mice in control group received intraperitoneally injections of same amount of normal saline. Serum amylase, creatinine, and ALT were examined and pathological evaluation of pancreatic tissues was performed. The expression of TREM-1 mRNA in peripheral blood leucocyte was determined by RT-PCR. The expression of TREM-1 protein in pancreatic tissue was detected by immunohistochemistry. Results Serum amylase, creatinine, and ALT in ANP 24 h were (9439 ± 1273)U/L, (84.8 ±75.9) μmol/L, ( 158.1 ± 122. 1 ) U/L, which were significantly higher than those in control group [ ( 2412 ± 297 ) U/L, (29.2 ± 19. 1 ) μmol/L, (41.4 ± 7.9 ) U/L) ]. The pathological scores of the pancreas in ANP group increased corresponding to time. The expressions of TREM-1 mRNA in ANP 24, 48,72, 96 h group were 15.55, 30.36, 15.77, 28.32, and the expressions of TREM-1 mRNA in ANP 48 h group was significantly higher than that in other groups ( P <0.01 ). The expressions of TREM-1 protein in the pancreas did not significantly change corresponding to time. Conclusions TREM-1 may be involved in the development of ANP by triggering other inflammatory factors.

Objective To compare the efficacy of different doses of intrathecal administration of morphine and fentanyl before operation for postoperative analgesia in patients undergoing abdominal hysterectomy.Methods Forty ASA Ⅰ or Ⅱ patients,aged 19-60 yr,undergoing abdominal hysterectomy under combined spinal-epidural anesthesia,were randomly divided into Ⅰ and Ⅱ groups (n =20 each).Morphine 0.5 mg+ fentanyl 15 μg and morphine 0.2 mg+ fentanyl 25 μg were injected intrathecally in groups Ⅰ and Ⅱ respectively.VAS score ≤2was considered as effective analgesia.When VAS score≥ 3,morphine 0.05 mg/kg was given intravenously as rescue analgesic.The incidence of nausea and vomiting and pruritus was recorded after operation.Results Compared with group Ⅰ,no significant change was found in the percentage of patients requiring rescue morphine after operation (P ＞ 0.05),the incidence of nausea and vomiting and pruritus was significantly decreased after operation and the time when the patients passed the flatus was significantly shortened after operation in group Ⅱ (P ＜ 0.05).Conclusion Intrathecal administration of morphine 0.2 mg and fentanyl 25.μg before operation is safer and more helpful to recovery of gastrointestinal function than intrathecal administration of morphine 0.5 mg and fentanyl 15 μg before operation if they can provide the equivalent postoperative analgesia.

Objective:To analyze the prognosis-related factors of ovarian serous adenocarcinoma in order to set up a prognostic model of serous adenocarcinoma and verify the effectiveness of the model as prognostic clinical criteria.Methods:The clinical, patholo-gical and follow-up data from 181 training samples with ovarian serous adenocarcinoma in Peking University First Hospital during January 1995 to December 2003 and another 42 detection samples with ovarian serous adenocarcinoma in Beijing Cancer Hospital during January 1999 to December 2005 were analyzed retrospectively. Kaplan-Meier univariate analysis was used to screen out prognostic factors; COX univariate and multivariate analyses were used to determine the risk coefficient of each factor and different layers in each factor; Pearson rank correlation analysis was used to identify the correlation of each factor. The prognostic model of ovarian serous adenocarcinoma was established on the conversion of risk coefficient to prognostic score and receiver operating characteristic (ROC) analysis was used to determine the cut-off value. The clinical data were collected to verify the sensitivity and specificity of the prognostic model based on the 3-year survival rate and Ki67 value.Results:The survival rate of patients with ovarian serous adenocarcinoma correlated with 6 factors including FIGO stage, histological grade, residual size, metastasis of lymph nodes, general condition after chemotherapy, and serum CA125 levels. The postoperative chemotherapy was an independent factor for prognosis. The prognostic model directly reflected the survival probability of classical COX risk ratio model, with higher score indicating lower survival probability and poorer prognosis. If combining prognostic score with Ki67 the sensitivity and specificity reached 64.7% and 96.0%, respectively.Conclusion:FIGO stage, histological grade, residual size, metastasis of lymph nodes, postoperative chemotherapy and serum CA125 were the prognostic factors of patients with ovarian serous adenocarcinoma. The prognostic model of ovarian serous adenocarcinoma can moderately reflect the actual survival status, and combination with Ki67 will increase the sensitivity and specificity.

Objective To investigate the changes in the levels of motilin in the gastric body in a rat model of incisional pain.Methods Eighty-four healthy male Sprague-Dawley rats,weighing 180-220 g,were randomized into 2 groups (n =42 each):normal saline group (NS group) and incisional pain group (P group).In group P an 1 cm long incision was made in the plantar surface of right hindpaw under sevotlurane anesthesia.Six rats were chosen from each group and paw withdrawal threshold to mechanical stimulation (MWT) and paw withdrawal latency to nociceptive thermal stimulation (TWL) were measured at 24 h before operation (To) and 1,6,24,48 and 72 h after operation (T1-5).Six rats were chosen from each group at T0-5 and sacrificed and the gastric mucosal tissues were prepared for measurement of motilin levels by ELISA.Results Compared with group NS,MWT,TWL and motilin levels were significantly decreased at T1-4 (P ＜ 0.05) and no significant change was found at T0 and T5 in P group (P ＞ 0.05).Compared with the baseline value at To,MWT,TWL and motilin levels were significantly decreased at T1-4,and no significant change was found at T5 in group P (P ＞ 0.05).MWT,TWL and motilin levels were significantly higher at T3-T5 than at T1 in group P (P ＜ 0.05).MWT,TWL and motilin levels were increased gradually at T3-T5 in P group (P ＜ 0.05).The motilin levels were positively correlated with MWT and TWL (r =0.9597 and 0.9231,respectively,P ＜ 0.01) in group P.Conclusion The levels of motilin in the gastric body is significantly decreased in a rat model of incisional pain and the decreasing range is positively corre lated with the degree of incisional pain.

Objective To investigate effects of intrathecal injection of morphine and fentanyl combined with low-dose naloxone on the pain behavior and the expression of blood motilin (MTL) in the rat model of incisional pain.Meth?ods A total of 72 healthy male Sprague-Dawley rats (weight 180-220 g), successfully intrathecally catheterized, were ran?domly divided into 6 groups (n=12 ):normal saline group (NS group), incisional pain group (P group), morphine (5μg/kg)+fentanyl (0.25μg/kg) group (MFP group), morphine+fentanyl+naloxone (0.2 ng/kg, 1 ng/kg, 5 ng/kg) group (MFPN1, MF?PN2 and MFPN3 groups). All groups except NS group were made the model of incisional pain on the right plantar surface. At 24-hours before intrathecal cathetherization (T0), 24-hours before modelling (T1), 1-hours (T2), 3-hours (T3) , 6-hours (T4), 24-hours (T5) , 48-hours (T6) and 72-hours (T7) after modelling respectively, paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were detected in right hind paw in 6 rats of each group. The other 6 rats in each group were sacrificed 6-hour after operation. The plasma expression of motilin was detected by ELISA. Re?sults Compared with NS group, the PWMT was not significantly different in all time points in MFPN2 group. The values of PWTL were significantly longer at T2 and T5 in MFPN2 group than those of NS group (P<0.05). The PWMT and the PWTL were significantly decreased at T2, T3 and T4 in P and MFPN3 groups than those of NS group (P<0.05).Compared with P group, the PWMT at T6, and PWTL at T3 and T4 were significantly decreased in MFPN3 group (P<0.05). The MTL at T6 was significantly decreased in P, MFP, MFPN1 and MFPN3 groups compared with that of NS group (P<0.05). There was no significant difference in MTL between MFPN2 group and NS group (P>0.05).Conclusion In the rat model of incision?al pain, intrathecal injection of naloxone at 1 ng/kg can inhibit the down-regulation of blood motillin caused by morphine and fentanyl, and which can up-regulate the PWTL, enhancing the analgesic effects of opioids.

Objective To evaluate the changes in the levels of motilin in the duodenum in a rat model of incisional pain.Methods Eighty-four healthy male Sprague-Dawley rats,aged 6-8 months,weighing 180-220 g,were randomized into 2 groups (n =42 each) using a random number table:control group (group C) and incisional pain group (group P).The animals were anesthetized with sevoflurane.In group P,a 1 cm long incision was made in the plantar surface of right hindpaw.Six rats were chosen from each group and mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 24 h before operation (T0) and 1,6,24,48 and 72 h after operation (T1-5).Six rats were chosen from each group at T0-5 and sacrificed and the duodenal mucosal tissue was prepared for measurement of motilin levels by ELISA.Pearson linear correlate analysis was performed between the motilin level and pain threshold at each time point in group P.Results Compared with group C,MWT was significantly decreased,TWL was shortened,and motilin levels were significantly increased at T1-4,and no significant change was found at T0 and T5 in group P.The motilin levels were negatively correlated with MWT (r =-0.8 910) and TWL (r =-0.8 463) in group P.Conclusion Incisional pain can promote the secretion of motilin in the duodenum.
