We reported a case of a work-related accident involving periorbital and intraorbital metal foreign bodies. The patient was a 43-year-old woman whose nasal dorsum was struck while she was sawing wood with nails. X-ray plain films of skull bone and computed tomographic scan of nasal sinus revealed two 5-mm-long metal objects lodged in right lacrimal sac and medial bulbar space of the right orbit. No deficits were noted in her visual acuities, visual fields, and ocular movements. Based on accurate positioning by imaging examination, transnasal endoscopic removal of metal foreign bodies was successfully accomplished. The patient recovered well without any complications after surgery.

Objective To observe the analgesic efficacy of epidural morphine for postpartum perineal pain in patients undergoing episiotomy.Methods After institutional reviewing board approval and patient consent,a total of 145 parturients requesting epidural labor analgesia and under-going episiotomy were randomized into three groups:M1,M2,and C,where in morphine 1 mg dis-solved in saline 10 ml,morphine 2 mg dissolved in saline 10 ml,or sole saline 10 ml was epidurally given immediately after umbilical cord clamp,respectively.Perineal pain at rest and movement within 24 hours after vaginal delivery were evaluated with present pain intensity (PPI).Further,the time in-terval between a moderate or severe PPI and epidural drug treatment were recorded.Besides,epidural morphine related side effects including nausea,vomiting,pruritus,and urinary retention were ob-served as well.Results The proportion of patients with moderate or severe pain at rest was signifi-cantly lower in group M2 (2.1%)compared to group M1 (15.7)and group C (19.1%)(P <0.05). Further,the time interval between a moderate or severe PPI and epidural drug treatment was signifi-cantly longer in group M2 (15.7±1.4 h)compared to group M1 (11.0±0.9 h)and group C (11.0 ±1.0 h)(P <0.05).No significant difference was found between groups M1 and group C with regard to morphine efficacy.However,the accumulated side effects including nausea,vomiting,pruritus, and urinary retention prominently increased in group M2 (102.1%)compared to group M1 (43.1%) and group C (12.8%)(P <0.05).Conclusion Although epidural morphine 2 mg may significantly decrease and postpone the occurrence of moderate or severe postpartum perineal pain,however,it de-serves consideration before clinical use owing to the increased side effects.

Objective To investigate the correlation between EEG severity and secondary epilepsy in elderly patients with cerebral infarction.Methods 128 cases with cerebral infarction were selected as the research subjects. According to whether the patients happened secondary epilepsy,they were divided into the observation group (65 cases) and the control group (63 cases).The difference of EEG severity between the two groups was compared,and its correlation with secondary epilepsy was analyzed.Results There were 18 cases (27.69%)in the observation group graded as moderate differences,which was significantly higher than that in the control group of 12 cases (19.05%), the difference was statistically significant (χ2 =4.43,P =0.04).There were 23 cases (35.38%)in the observation group graded as severe differences,which was significantly higher than that in the control group of 9 cases (13.85%),the difference was statistically significant (χ2 =6.51,P =0.01 ).There were 21 cases(32.31%)of EEG changes of observation group being only diffuse abnormalities forms,which was significantly higher than that of the control group of 11 cases(17.46%),the difference was statistically significant (χ2 =4.18,P =0.04).There were 28 cases(43.08%)of EEG changes of the observation group being both focal abnormalities and diffuse abnor-malities forms,which was significantly higher than that of the control group of 14 cases(22.22%),the difference was statistically significant (χ2 =5.40,P =0.02).Compared open -closed test,hyperventilation provocation test results of the observation group being abnormal or not fit with the control group,the difference was not statistically significant (P >0.05).Conclusion According to the classification of EEG,EEG changes and EEG related tests to determine the severity of EEG.The more severe EEG,the greater the possibility of secondary epilepsy happen in patients with cerebral infarction.

Objective To explore the methods of thoracoscopic intrapleural perfusion hyperthermic chemotherapy(TIPHC)on diagnosing and treating malignant pleural effusion caused by lung cancer,as well as its effect.Methods From February 1999 to March 2006,seventy patients with malignant pleural effusion caused by lung cancer were randomly divided into therapeutic group(35 cases)and control group(35 cases).Pleural biopsy and TIPHC under general anesthesia with unilateral ventilation were performed in the therapeutic group,and intrapleural injection of cisplatin was administered in the control group after drainage of pleural effusion.The effect on malignant pleural effusion,the change for the concentration of carcino-embryonic antigen(CEA),cytokeratin-19 fragments(CYFRA21-1),neuron-specific enolase(NSE)and the side effect were compared before and after the treatment.Results The therapeutic group achieved total response rate of 100%,but only 54.3% in the control group,with significant difference(P

Indirect fluorescent antibody test (IFAT) using frozen sections of Brugia malayi adult worms as antigen was employed in the diagnosis and epidemiological investigation of human filariasis. Sera were collected from 704 cases with bancroftian or malayan microfilaremia. the positive rate was 92.8-99.1%. Of 150 healthy people from non-endemic areas, only one showed a positive reaction (false positive rate 0.7%) (Table 1). This technique proved to be highly sensitive and specific for the diagnosis of filariasis and the antigen is easy to prepare. It might be used in sero-epidemiological investigation for the assessment of filariasis control.

Objective To construct small hairpin RNA(shRNA) lentiviral vectors targeting human a proliferation-inducing ligand(APRIL) gene and detect the titer of virus and suitable multiplicity of infection (MOI) after 293T cells were infected by the lentival vectors. Methods Three RNA interference targeting sequences of APRIL gene were screened including shAPRIL1210, shAPRIL1754 and shAPRIL1604. Both sense and antisense Oligo DNA of the targeting sequences were synthesized and cloned into the pGCL-GFP vector, respectively. The resulting lentiviral vectors containing shAPRIL were named LV-shAPRIL1210, LV-shAPRIL1754, LV-shAPRILI604. Then they were confirmed by PCR and DNA sequencing. 293T cells were co-transfected with LV-shAPRIL, pHelper 1.0 and pHelper 2. 0 to product lentivirus, respectively. The titer of virus and suitable MOI were tested according to the expression level of GFP in the 293T cells. Results PCR analysis and DNA sequencing confirmed that three shAPRIL DNA were successfully inserted into the lentiviral vectors. The titers of concentrated virus were 5 × 107, 6 × 107 and 4 × 107(transduction units )TU/ml, respectively, and the suitable MOI was 5. Conclusions Three shRNA lentiviral vectors targeting human APRIL gene have been successfully constructed, which lays a foundation for future studying APRIL's gene silencing in related target cells.

Among them, compound 12d (trans-3, 4, 5, 4'-tetrahydroxystilbene) exhibits the most potent anti-HIV-1 activity with an IC50 value of 1.84 micromol x L(-1).

Objective To investigate the inhibitive effect of shRNA (short hairpin RNA) targeting APRIL gene on the pancreatic cancer cells in vitro and in vivo, in order to explore the feasibility of gene therapy for pancreatic cancer. Methods The LV-shAPRIL targeting APRIL gene had been constructed before, and was used to infect the CFPAC-1 cells. Cell proliferation and apoptosis were examined by MTT and flow cytometry. Then CFPAC-1 cells were used to construct the model of transplantation tumor into the nude mice, the tumor growth was assessed after LV-shAPRIL treatment. Results 96 hours after the LV-shAPRIL infection into CFPAC-1 cells, the cell proliferation was significantly inhibited when compared with control group and lentivirus infection group (P＜0.05 ). Flow cytometry showed the apoptosis ratio of the CFPAC-1 cells was (17.35±0.96)% in LV-shAPRIL group, which was higher than that in control group and lentivirus infection group (P＜0.05 ). After LV-shAPRIL injection into the model of nude mice, the tumor growth was slower than that in the two control groups. The tumor's volume of the LV-shAPRIL group was(821.8±123.3) mm3 and the mass was (2.16±0.18)g at 27 day, and were obviously depressed, when compared with two control groups (P±0.05). Conclusions LV-shAPRIL targeting APRIL gene can inhibit the growth of the CFPAC-1 cells in vitro and vivo. This may provide a new gene therapy approach for pancreatic cancer.
