2.Construction and identification of lentiviral vector of RNA interference of GF?1 gene
Journal of Chongqing Medical University 1987;0(01):-
Objective: To construct a lentiviral vector of RNA interference(RNAi) of TGF-?1 gene. Methods: Three target sequences were selected according to TGF?1 mRNA sequence firstly,then three pairs of oligonucleotide sequences according to these target sequences and one pair of negative control oligonucleotide sequence were designed and synthesized. The annealed oligonucleotide fragments were subcloned into pRNA-U6/Lenti plasmid. After identified by restriction enzyme digestion and sequencing ,these plasmids were cotransfected along with ViraPowerTM Lentiviral Packaging Mix into 293FT cells for the package of lentiviral particles. Then the lentiviral vector particles were transfected into Hela cells and TGF-?1 expression in the transfected cells was assayed by Real-Time PCR and ELISA. Results: It was confirmed by digestion and sequencing that lentiviral vectors had the correct structure and could express high titer of virus. After transfected into Hela cells,TGF-?1 expression was decreased significantly by two of these lentiviral vectors at both the protein and mRNA level and the first vector had the best interefence efficiency. Conclusion: The lentivirus RNAi vector of TGF-?1 was constructed successfully.

Methods:
The incidence and mortality of lung cancer in Kaihua County from 2011 to 2022 were collected through Zhejiang Provincial Chronic Disease Surveillance Information Management System. The crude incidence, standardized incidence, crude mortality and standardized mortality of lung cancer were analyzed, and the trends in incidence and mortality of lung cancer were evaluated using average annual percent change (AAPC).
Results:
The crude and standardized incidence of lung cancer appeared a tendency towards an increase (AAPC=5.409% and 2.957%, both P<0.05) from 2011 to 2022, with an average annual crude incidence of 75.17/105 and average annual standardized incidence of 44.37/105. Average annual crude incidence (100.16/105 vs. 48.55/105) and standardized incidence (58.03/105 vs. 30.61/105) of lung cancer was higher in males than in females (both P<0.05). The crude incidence of lung cancer in males appeared a tendency towards an increase (AAPC=2.878%, P<0.05), with no significant changing patterns seen in standardized incidence (P>0.05). The crude and standardized incidence of lung cancer in females showed a tendency towards an increase (AAPC=11.596% and 10.464%, both P<0.05). The crude incidence of lung cancer increased rapidly among residents at ages of 45 years and older, and peaked among residents at ages of 80 to 84 years (32.11/105). The crude and standardized mortality of lung cancer appeared a tendency towards a rise and decline (AAPC=1.554% and -2.491%, both P<0.05) from 2011 to 2022, with an average annual crude and standardized mortality of 52.83/105 and 29.09/105. Average annual crude mortality (77.92/105 vs. 26.10/105) and standardized mortality (43.66/105 vs. 14.33/105) of lung cancer was higher in males than in females (both P<0.05). The crude mortality of lung cancer in males appeared a tendency towards a rise, while the standardized mortality appeared a tendency towards a decline (AAPC=1.436% and -2.553%, both P<0.05). No significant changing patterns were seen in crude and standardized mortality of lung cancer in females (both P>0.05). The crude mortality of lung cancer increased rapidly among residents at ages of 50 years and older, and peaked among residents at ages of 80 to 84 years (37.26/105).
Conclusions
The incidence and mortality of lung cancer appeared a tendency towards an increase in Kaihua County from 2011 to 2022, and a rapid increase was seen in the incidence of lung cancer in females.

7.Expression of pro-inflammatory cytokine mRNA after spinal cord injury and effect of the methylprednisolone in rats
Chinese Journal of Rehabilitation Theory and Practice 2005;11(2):91-93
ObjectiveTo investigate the expression of pro inflammatory cytokine mRNA including interleukin 1β (IL-1β), interleukin 6 (IL-6) and tumor necrosis factor-α(TNF-α) after spinal cord injury (SCI), and the effect of methylprednisolone (MP) on the expression of the cytokine and neurological outcome after SCI in rats.MethodsA moderate SCI model was made with SD rats according to modified Allen's method. 56 SD rats were divided randomly into the sham group (n=4), SCI group (n=24), saline group (n=14) and MP group (n=14, MP 30 mg/kg injected throuh tail vein 30 min after injury). Samples of injured spinal cord were taken at 1 h, 4 h, 12 h, 24 h, 72 h and 7 day after SCI. The mRNA expressions of IL-1β,IL-6 and TNF-α in the spinal cord of rats were measured by semi-quantitative RT-PCR at 1 h, 4 h, 12 h, 24 h, 72 h and 7 d post-injury, and 4 h post-operation in the control group. The effect of MP (30 mg/kg, iv, within 30 minutes post-injury) on the expression of cytokine at 4 h post-injury was tested with RT-PCR. The neurological outcome of rats was evaluated with BBB scores.ResultsThe expression of the cytokine mRNA was little in the sham group and significantly increased in injured groups with IL-1β at 12 h, TNF-αat 4 h reaching peak after injury,and higher than that in sham group until 72 h (P<0.05). While, the expressions of IL-1β and TNF -α mRNA were inhibited obviously in MP group at 4 h after injury, but MP had no effect on the neurological outcomes.ConclusionMP can inhibit inflammatory reaction obviously.
8.Recent progress in the improvement of the coupling efficiency of "difficult sequences" in peptide synthesis
Acta Pharmaceutica Sinica 2007;42(2):111-117
Even though chemistry is now in place that potentially allows high coupling efficiencies to be attained, successful coupling is usually a challenge when so-called "difficult sequences" is encountered in peptide synthesis. Some factors that affect the coupling efficiency have been discussed and related methods to overcome those obstacles have been introduced in present review. All suggestions proposed here are valuable and also feasible to improve the coupling completeness in both liquid-phase or solid-phase peptide synthesis.
9.Strategies of nutritional support for patients with hyperlipidemic acute pancreatitis
Chinese Journal of Clinical Nutrition 2011;19(1):25-27
Objective To summarize the strategies of nutritional support for patients with hyperlipidemic acute pancreatitis (HLAP). Methods The clinical data of six HLAP patients who were treated in our department from January 1998 to December 2009 were retrospectively reviewed. Results The disease conditions of all patients were improved after fasting and early nutritional support and lipid-lowering treatment. Three cases with severe HLAP received enteral nutrition via a nasojejunal tube. Another three patients with milder HLAP obtained low-fat diet and orally administered lipid-lowering drugs. The plasma triglyceride levels decreased from (25.30 ± 20. 48 ) mmol/L to (5.41 ±4.55) mmol/L. No relapse was noted during follow-up (range: 3 -24 months). Conclusions The approaches of nutritional support for HLAP patients should be customized based on the specific disease conditions,and the enteral nutrition and lipid-lowering drugs should be reasonably and carefully designed and applied. For severe HLAP, nasojejunal tube should be maintained in the early stage to ensure the application of enteral nutrition and lipid-lowering drugs, protect the integrity of gut mucosal barrier, and decrease the fluctuation of blood glucose.

Chinese Journal of Geriatrics 2013;(4):397-399
Objective To evaluate the efficacy of intraperitoneal hyperthcrmic chemoperfusion in combination with interleukin 2 in the treatment of malignant ascites.Methods A total of 47 patients aged 47-75 years with malignant ascites were randomly divided into two groups:the experimental group and the control group.All patients received a closed drainage and were treated with paclitaxel liposome,cisplatin (DDP),interleukin-2 and dexamethasone by intraperitonealinfusion.Patients were asked to change the body position.In addition,the patients in experimental group were received the high frequency hyperthermia immediately at a temperature of 42℃ to 43℃ for 90 minutes.Results The remission rate (RR) was higher in the experimental group than in the control group (75.0 % vs.43.5%,x2 =4.85,P<0.05).The median survival time (MST) was longer in the experimental group than in the control group (34 weeks vs.21 weeks,P<0.05).There were no significant differences in adverse reaction incidences between groups (P > 0.05).Conclusions Compared with intraperitoneal chemoperfusion alone,the intraperitoneal hyperthermic chemoperfusion has a higher RR and longer MST with no increased adverse reaction incidence,which can be in the clinical application.
