Objective To study the application of stomach tube insertion in the lateral recumbent position in rescuing the unconscious patients,to reduce the discomfort of patients and increase the one-time success rate in the insertion of stomach tube. Methods 100 cases of unconscious patients were divided into the control group and the treatment group with 50 cases in each, they adopted routine tube insertion method and tube insertion in the lateral recumbent position.The success rate of tube insertion and incidence of complications were collected and analyzed in the two groups.Results The experimental group had a higher success rate and less complications compared with the control group.Conclusions The lateral recumbent position for stomach tube insertion is the ideal position for the unconscious patients.

Objective To observe he effects of new Tangshenkang on α-SMA and E-cadherin of human renal tubular epithelial cell HK-2 in high concentrations of glucose; To explore the mechanism of new Tangshenkang on the prevention and treatment of diabetic renal fibrosis. Methods The HK-2 cells were cultured and divided into control group, high glucose group, animal serum control group, new Tangshenkang low-, medium-, and high-dosage group. After medicine intervention, cell proliferation was tested by MTT assay, and contents of α-SMA and E-cadherin were observed by ELISA assay. Results Compared with control group, α-SMA of HK-2 cultured with high glucose was much notable, but the content of E-cadherin significantly decreased, with statistical significance (P<0.05). The content of α-SMA of HK-2 cultured with new Tangshenkang decreased, and the content of E-cadherin increased; cell proliferation was markedly inhibited in culture medium supernatant of HK-2 cells cultured with high glucose plus new Tangshenkang compared with only high glucose, with statistical significance. Conclusion New Tangshenkang can inhibit cell proliferation and epithelial-myofibroblast transdifferentiation of HK-2 cell induced by high glucose, and prevent the development of diabetic renal fibrosis to a certain extent.

Objective : To evaluate the effect of Arthroscopic Treatment of Popliteal Cyst through the modified double posteromedial portal． Methods : A total of 210 patients who diagnosed with popliteal cyst between April 2019 and June 2021 were chosen．62 patients underwent surgical treatment，include open excision and arthroscopic surgery．At the same time，31 patients with conservative treatment were included as conservative treatment group．The Visual Analogue Score( VAS score) ，Lysholm knee function score，and Knee Society Score ( KSS) scores were as- sessed before and 3 months after the operation. Results : In the open excision group，preoperative VAS score was 3. 69 ± 0. 93，Lysholm score was 63. 75 ± 4. 76，KSS score was 60. 87 ± 5. 85，and postoperative VAS score was 2. 04 ± 1. 04，Lysholm score was 76. 81 ± 6. 35，KSS score was 70. 42 ± 4. 87．In the arthroscopic surgery group，preoper- ative VAS score was 3. 81 ± 0. 84，Lysholm score was 62. 84 ± 4. 85，KSS score was 58. 95 ± 4. 79，and postoperative VAS score was 1. 47 ± 0. 85，Lysholm score was 82. 35 ± 7. 34，KSS score was 78. 52 ± 5. 67．In conservative treatment group，preoperative VAS score was 3. 92 ± 1. 02，Lysholm score was 61. 39 ± 3. 92，KSS score was 62. 42 ± 6. 78，and postoperative VAS score was 3. 94 ± 1. 14，Lysholm score was 61. 85 ± 7. 48，KSS score was 60. 52 ± 6. 37．Significant improvement was observed in all the measurements after the operation compared to before the oper- ation(P ＜0. 001 ) ．Compared with the open excision group，the arthroscopic surgery group improved better (P < 0. 05) ． Conclusion Arthroscopy through the modified double posteromedial portal in the treatment of popliteal cyst has satisfactory results.

Ovarian cancer is one of the most serious gynecological tumors in the world, and its mortality ranks first in gynecological malignancies. The study found that metformin is not only used as a first-line oral hypoglycemic agent for the treatment of type 2 diabetes, but also has a certain inhibitory effect on the occurrence and development of ovarian cancer. In recent years, domestic and foreign scholars have carried out experimental and epidemiological studies on the relationship between metformin and ovarian cancer. This review included 7 cohorts and 2 case-control studies on the incidence and prognosis of metformin and ovarian cancer. The results suggest that the use of metformin may improve the prognosis of ovarian cancer, however, due to the limited epidemiological studies of the disease, its relationship with ovarian cancer still needs further exploration.
