Objective:To observe the curative effect of local application of minocycline-HCl ointments and the influence on high sensitivity C reaction protein (hs-CRP) and interleukin-10 (IL-10) levels in gingival crevicular fluid of patients with chronic periodon-titis. Methods:Totally 72 cases of patients with chronic periodontitis (96 teeth) were selected and divided into the observation group (36 cases, 47 teeth) and the control group (36 cases, 49 teeth) by a random number table. The patients in the two groups were given the routine periodental non-surgical treatment, such as supragingival scaling, subgingival scaling, scaling and root planning etc. The patients in the observation group were given minocycline-HCl ointments filled in the periodontal pockets, and the patients in the control group were given compound iodine glycerol liquids filled in the periodontal pockets once a week for 4 weeks. The changes in hs-CRP and IL-10 levels in gingival crevicular fluid of the patients before and after the medical treatment were observed, and the clinical cura-tive effect was compared as well. Results:After the 4-week medical treatment, the hs-CRP levels in gingival crevicular fluid of the pa-tients in the two groups were obviously declined, while the IL-10 levels were obviously increased(P<0. 01 or P<0. 05), and the de-clining or increasing rate in the observation group was much higher than that in the control group (P<0. 05). The total clinical effi-ciency in the observation group was 94. 44%, which was much higher than that in the control group (77. 78%, P<0. 05). Conclu-sion:The local application of minocycline-HCl has favorable curative effect on chronic periodontitis, which can reduce the hs-CRP lev-els in gingival crevicular fluid, increase the IL-10 levels, control the inflammatory damage in periodontium effectively and improve the local inflammatory reaction in periodontium.

Objective To investigate the related risk factors for progress of the elderly frontal lobe contusions. Methods The clinical data of 118 cases of elderly frontal lobe contusions from August 2012 to August 2014 were retrospectivelyanalyzed.118 patients were given conventional therapy after admission,received dynamic review of brain CT.The progress of patients were performed surgery of frontal coronary approach,removed contusion brain tissue by bone flap of single frontal or double the frontal lobe.No progress of patients were given conventional conservative treat-ment.Selected seven indicators combining with hypertension,oral aspirin,diabetes mellitus,contrecoup injury,Cushing response,sylvian cistern exist or not and subdural hematoma did a statistical analysis.Results This group of 118 patients,68 cases (57.6%)had progress and 50 cases (42.4%)had no progress.Statistical analysis showed that oral aspirin (P =0.006 ),sylvian cistern exist or not (P =0.001 ),Cushing response (P =0.025 )were independent risk factors of progress of the elderly frontal lobe contusions.Conclusion For elderly patients with fron-tal lobe contusion,oral aspirin,sylvian cistern exist or not,whether there is any Cushing response were risk factors for deterioration of disease progression.If one or more risk factors appeared,clinical need to prevent disease progression.

Objective To obtain highly expressing cell lines by inserting the glutamine synthetase (GS) screening system and replacing the promoter of the vector.Methods The mutation of the point BamHⅠwas induced to build a new vector pIRES2-EGFP.The marker gene GS was inserted by AseⅠ and NheⅠ, and the promoter hCMV was replaced by PacⅠand NheⅠ.The new vector pHGS1.0 and the vector pIRES2-enhanced screen fluorescein protein( EGFP)-B were inserted by the recombinant protein TEM8 ( 1-227 )-VEGFR1 domain2-IgG2 ( TV-IgG2 ) gene to analyze the advantages of the expression.Results The glutamine synsthetase is successfully inserted, the human cytomegalovirus replaced, and recombinant protein is increased 5-fold by human immunoglobulin quantification kit.Conclusion The GS system is a highly protein expressing system.

Objective:To evaluate the clinical prognosis of patients with pseudomyxoma peritonei (PMP) after cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC).Methods:The clinical data of 42 patients with PMP after CRS combined with HIPEC in the Affiliated Haikou Hospital of Xiangya Medical College of Central South University from January 2012 to December 2018 was retrospectively analyzed. All patients underwent open surgery CRS combined with HIPEC, the operation condition and prognosis of patients were analyzed.Results:In 42 patients with PMP, the disenminated peritoneal adenomucinosis (DPAM) accounted for 61.9% (26/42), the peritoneal mucinous carcinomatosis (PMCA) accounted for 28.6% (12/42), and the borderline accounted for 9.5% (4/42). The incidence rate of major operative complications (grade Ⅲ-Ⅳ) after CRS combined with HIPEC was 21.4% (9/42). The logistic regression analysis showed that the previous surgery score ( OR = 35.765, 95% CI 2.746-43.986, P = 0.001) and completeness of CRS score ( OR = 23.865, 95% CI 1.345-347.876, P = 0.028) were independent factors influencing major postoperative complications in PMP patients. The overall survival time of 42 patients with PMP was (64.8±4.1) months, and the disease-free survival time was (54.0±4.9) months; the 3-year and 5-year overall survival rates were 80.8% and 65.9%, and the 3-year and 5-year disease-free survival rates were 59.5% and 54.6%, respectively. The difference in overall survival time of patients with different pathological subtypes was statistically significant ( P = 0.022). Conclusion:CRS combined with HIPEC is safe and effective for treatment of patients with PMP, and most of the patients have a good prognosis.
