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 relationship between alexithymia and event-related potential P300 in patients with somatoform disorders.Methods Forty-two patients aged 18 to 65 years fulfilling ICD-10 diagnosis criteria for somatoform disorders were recruited as experiment group.Forty normal healthy persons were selected as control group.The Toronto alexthymia scale-20 (TAS-20) was employed to investigate the alexithymia of the subjects.P300 potentials was employed to investigate the cognitive ability of the subjects.A comparison was made between the patients and the healthy subjects.Results The latencies of N1,P2,N2 and P3 were significantly longer in patients with somatoform disorder than those in the normal controls (P ＜ 0.05 or 0.01),the amplitudes of N2 and P3 were significantly lower in the patients (P ＜ 0.05 or 0.01).The three factors scores and the total score of TAS-20 test in patients with somatoform disorder were significantly lower than those in the normal controls (P ＜ 0.05 or 0.01).There was significant correlation between the latency and the three factors scores and the total score of TAS-20 as well as between the amplitude of P300 and the three factors scores and the total score of TAS-20:the latencies of N1,P2,N2 and P3 recorded at Pz was positively correlated with the factors scores (r =0.32 ～ 0.48,P ＜ 0.05 or 0.01),and the amplitudes of N1,P2,N2 and P3 recorded at Pz was negatively correlated with theTAS-20 scores (r=-0.31 ～-0.51,P＜0.05 or0.01).Conclusions There existed significant correlation between the alexithymia and cognitive impairment in patients with somatoform disorders.Both alexithymia and event-related potential P300 can be used as a clinical evaluation index for patients with somatoform disorder.

Around the world, the supply of health services faces challenges, especially in developing nations that suffer from inadequate infrastructure and aging equipment, frequent shortages of medicine and supplies, and low capacity and efficiency of primary health care. At present, more and more governments adopt public-private partner-ships to achieve public policy goals. Among those, Brazil, South Africa, and India have made greater achievements in changing the roles of local government, increasing the supply of primary health care and health care quality, pro-moting health care equality, meeting the needs of multi-level medical services, and promoting health capabilities by using public-private partnerships. This paper provides an overview of public-private partnership practices in the three countries, discusses their reform experiences, and concludes with implications which may be helpful for promoting and scaling up PPP in primary health care in China.

Objective To construct of shRNA lentiviral expression vector targeting APRIL (aproliferation-inducing ligand) gene in CFPAC-1 cell of human pancreatic cancer. Methods We used gene engineering to screen RNA interference targeting sequence of APRIL gene. The complementary DNA containing both sense and antisense Oligo DNA of the targeting sequence was designed, synthesized and cloned into the pGCL-GFP vector. The resulting lentiviral vector containing shAPRIL were named LV-shAPRIL. Then it was conformed by PCR and DNA sequencing identification. 293T cells were eotransfected with LV-shAPRIL,pHelper 1.0 and pHelper 2.0 to product ientivirus. The titer of virus was tested according to the expression level of GFP in the 293T cells. After recombinant lentivirus infection into CFPAC-1 cells, we used real-time RT-PCR and Western blotting to examine APRIL mRNA and protein expression at different cell culture period.Results PCR analysis and DNA sequencing conformed that shAPRIL DNA was successfully inserted into the lentiviral vector. The titer of concentrated virus were 5 × 107 TU/ml. APRIL expression in CFPAC-1 cells were inhibited significantly at both mRNA and protein level. APRIL mRNA expression were decreased 73%, 70%and 71% , respectively, after the infection of 4 days, 4 weeks and 8 weeks by LV-shAPRIL. APRIL protein expression were decreased 66%, 63% and 62%, respectively , after the infection of 4 days , 4 weeks and 8weeks by LV-shAPRIL. Conclusions ShRNA lentiviral expression vector targeting APRIL gene has been successully constructed, and it can effectively inhibit the expression of APRIL gene in CFPAC-1 ceils. This study lays a foundatin for in vivo research APRIL gene scilence in pancreatic cancer cell using the model of nude mice.

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.
