Objective:Investigate the awareness of their own rights and the safeguarding of the rights in practice,raise the patients' sense of safeguarding of the rights and help them defend the legal rights.Methods:A survey was taken among patients by applying the questionnaire.Results:There are 5 items about the patients' knowledge about their own rights and 3 items about defending their rights in practice,in which more than 85 percent of 111 patients chose the answer "always or almost".From this we can see that the awareness and safeguarding of their rights are not good enough.Conclusion: The government is appealed to break up the existence of the monopoly mold in medical treatment and to take measures to protect the rights of patients.The medical personnel should renew their concepts,pay more attention to publicizing and defending patients' rights,and help patients realize their rights.

Objective: To investigate the effect of hydrogen sulifde (H2S) on the expression of CSE, NF-κB, and IL-8 mRNA in GES-1 cells withHelicobacter pylori (H. pylori) infection and to explore its mechanism on gastric mucosa inlfammation caused byH. pylori.
Methods: GES-1 cells were cultured for 24 h and divided into a control group (neitherH. pylori nor NaHS), anH. pylori group, a NaHS group (which was further divided into 4 groups at 50, 100, 200, or 400 μmol/L NaHS), andH. pylori + NaHS group (which was further divided into 4 groups at 50, 100, 200, or 400 μmol/L NaHS). Each group was then cultured for 3, 6, or 12 h. The expression of CSE, NF-κB, and IL-8 mRNA was measured by RT-PCR, and their correlation was analyzed. Results: The expression of CSE, NF-κB, and IL-8 mRNA in GES-1 cells in theH. pylori group was higher than that in the control group. The expression of CSE in the 200 μmol/L NaHS group and 400 μmol/L NaHS group was lower than that of the control group (P<0.05), whereas the expression of NF-κB and IL-8 in all NaHS groups had no statistical differences compared with the control group (P>0.05). The expression of CSE, NF-κB, and IL-8 mRNA in all groups of NaHS,H. pylori + 200 μmol/L NaHS group, andH. pylori + 400 μmol/L NaHS group was lower than that in theH. pylori group (P<0.05). There was positive correlation among the expressions of CSE, NF-κB, and IL-8 mRNA in theH. pylori group, theH. pylori + 200 μmol/L NaHS group, and theH. pylori +400 μmol/L NaHS group (P<0.05).
Conclusion:H. pylori can induce NF-κB and IL-8 mRNA expression and upregulate CSE mRNA expression. At 200 and 400 μmol/L, NaHS can suppressH. pylori-induced NF-κB and IL-8 mRNA expression and ameliorate the morphology ofH. pylori-induced GES-1 injury, which may protect gastric epithelial cells byH. pylori infection.

Objective:To explore the clinical evaluation and management of placenta previa with placental implantation, in order to improve the diagnosis and treatment level of placenta previa with placental implantation.Methods:A retrospective analysis was conducted on the case data of two patients with high-risk placenta previa and placental implantation confirmed at the Third Affiliated Hospital of Southern Medical University. Based on previous reports, experience and shortcomings were summarized.Results:Selective surgery can reduce bleeding in placenta previa with placental implantation patients and reduce the risk of bleeding; Multi disciplinary consultation and multiple methods of hemostasis are important treatment measures for placenta previa with placental implantation; Preventive intervention measures need to fully evaluate the condition, taking into account factors such as the patient′s economic burden and intervention related complications.Conclusions:Standardized pregnancy management, multidisciplinary diagnosis and treatment, and the application of various surgical hemostasis measures can improve the success rate of placenta previa with placental implantation treatment.

Background:Cholangitis is common in patients with advanced cholangiocarcinoma after endoscopic metal biliary endoprothesis (EMBE). Aims:To explore the effect of EMBE combined with endoscopic nasobiliary drainage (ENBD)on preventing post-ERCP cholangitis in patients with cholangiocarcinoma. Methods: A total of 263 advanced cholangiocarcinoma patients underwent EMBE were enrolled and divided into EMBE group and EMBE plus ENBD group. Incidence of post-ERCP cholangitis,adverse event rate and hospital stay were evaluated between the two groups. Results:Compared with EMBE group,incidence of post-ERCP cholangitis (2. 3% vs. 10. 8%,P ＝0. 032 )and hospital stay [(4. 68 ± 1. 43)days vs. (5. 18 ± 1. 45 )days,P ＝0. 011 ]were significantly lower in EMBE plus ENBD group, especially in patients with hilar cholangiocarcinoma [incidence of post-ERCP cholangitis:3. 5% vs. 15. 0%,P＝0. 045;hospital stay:(5. 18 ± 1. 44)days vs. (5. 68 ± 1. 39)days,P＝0. 033]. C-reactive protein,white blood cell count, percentage of neutrophil after 3,24,72 hours were significantly decreased in EMBE plus ENBD group than in EMBE group (P＜0. 05). No significant difference in procedure-related adverse event was found between the two groups (P＞0. 05). Conclusions:The combination of EMBE with ENBD is safe and effective in preventing post-ERCP cholangitis,especially in patients with hilar cholangiocarcinoma.

There is accumulating evidence that microRNAs are emerging as pivotal regulators in the development and progression of neuropathic pain. MicroRNA-15a/16 (miR-15a/16) have been reported to play an important role in various diseases and inflammation response processes. However, whether miR-15a/16 participates in the regulation of neuroinflammation and neuropathic pain development remains unknown. In this study, we established a mouse model of neuropathic pain by chronic constriction injury (CCI) of the sciatic nerves. Our results showed that both miR-15a and miR-16 expression was significantly upregulated in the spinal cord of CCI rats. Downregulation of the expression of miR-15a and miR-16 by intrathecal injection of a specific inhibitor significantly attenuated the mechanical allodynia and thermal hyperalgesia of CCI rats. Furthermore, inhibition of miR-15a and miR-16 downregulated the expression of interleukin-1β and tumor-necrosis factor-α in the spinal cord of CCI rats. Bioinformatic analysis predicted that G protein-coupled receptor kinase 2 (GRK2), an important regulator in neuropathic pain and inflammation, was a potential target gene of miR-15a and miR-16. Inhibition of miR-15a and miR-16 markedly increased the expression of GRK2 while downregulating the activation of p38 mitogen-activated protein kinase and NF-κB in CCI rats. Notably, the silencing of GRK2 significantly reversed the inhibitory effects of miR-15a/16 inhibition in neuropathic pain. In conclusion, our results suggest that inhibition of miR-15a/16 expression alleviates neuropathic pain development by targeting GRK2. These findings provide novel insights into the molecular pathogenesis of neuropathic pain and suggest potential therapeutic targets for preventing neuropathic pain development.
