1.Mild moxibustion plus loratadine tablets for children with allergic rhinitis: a randomized controlled trial
Journal of Acupuncture and Tuina Science 2021;19(6):419-424
Objective: To explore the efficacy of mild moxibustion plus loratadine tablets for children with allergic rhinitis (AR).Methods: A total of 80 children were randomized into a control group and an observation group, with 40 cases in each group. The control group was treated with loratadine tablets, and the observation group was treated with mild moxibustion plus loratadine tablets. Before and after treatment, the total nasal symptom score (TNSS) was evaluated, and the serum eosinophils (EOS) count, and the interleukin (IL)-27 and macrophage migration inhibitory factor (MIF) levels were measured. Clinical efficacy was evaluated after treatment. Results: The total effective rate of the observation group was higher than that of the control group (P<0.05). After treatment, the TNSS in both groups decreased (P<0.05), and the TNSS in the observation group was lower than that in the control group (P<0.05); the serum EOS count in both groups decreased (P<0.05), and the serum EOS count in the observation group was lower than that in the control group (P<0.05). The serum IL-27 level in the control group had no statistical difference compared with the same group before treatment (P>0.05), and the serum MIF level decreased after treatment (P<0.05). The serum IL-27 level in the observation group increased after treatment (P<0.05), and the serum MIF level decreased after treatment (P<0.05), and were both statistically different from those in the control group (P<0.05). Conclusion: Mild moxibustion plus loratadine tablets is effective in treating children with AR. It can significantly improve the nasal symptoms and reduce the serum EOS count, which may be related to the regulation of the serum IL-27 and MIF levels.

Treating different diseases with the same method is a unique original thinking in Chinese medicine, which embodies the spirit of treatment based on syndrome differentiation. We briefly reviewed the origin and development of this concept. We also reviewed that thinking of combination of disease and syndrome is its premise and foundation. We put forward the conditionality of diseases in treating different diseases with the same method by cutting-in modern biological basic researches, that is to say, one kind specific diseases or disease of one specific system. We emphasized the importance of diseases conditionality in treating different diseases with the same method, which was of great significance in studies on combination of disease and syndrome, correspondence of prescription and syndrome, and modern biological basic researches of treating different diseases with the same method.

3.Purification and ATPase activity analysis of human PIF1 helicase participating in DNA repair
Chinese Journal of Endemiology 2009;28(3):276-279
Objective To clone, express and purify human PIF1 protein and analyze its ATPase activity. Methods The PIF1 cDNA was amplified by PCR from HeLa cell cDNA library and inserted to pET24b with histidine tag at its terminus to form pET24b-PIF1 plasmid. The recombinant pET24b-PIF1 plasmid was transformed to RosettaTM 2 (DE3) and the expression of PIF1 protein was monitored by SDS-PAGE analysis. By using fast protein liquid chromatograph (FPLC) system, the PIF1 protein was purified by affinity chromatograph and gel filtration. The ATPase activity of PIF1 was checked by thin layer chromatograph(TLC). Results The PIF1 protein was successfully cloned and expressed in E.coli. Conclusions The purification procedure of PIF1 protein was established using FPLC. The overexpressed and the purified PIF1 helicase has DNA and Mg2+ dependent ATPase activity.
4.Influence of interleukin-11 on graft versus host disease and graft versus leukemia after allogenic bone marrow transplantation in acute lymphoblastic leukemic junior rats
Journal of Applied Clinical Pediatrics 1992;0(06):-
Objective To study the influence of interleukin-11 (IL-11) on graft versus host disease(GVHD) and graft versus leukemia(GVL) after allogenic bone marrow transplantation and related mechanism in acute lymphoblastic leukemic(ALL) junior mice.Methods The impact of IL-11 on CD4 and CD8 T cell after transplantation was evaluated by flow cytometry;it was observed that the GVHD pathology chance of internal after transplatation in ALL junior mice;the survial time after transplantantion was recorded;the level of tumor necrosis factor-?(TNF-?) which evidently related to GVHD was evaluated by ELISA.Results IL-11 could decrease the quantity of CD4 T cell and increase CD8 T cell;IL-11 could obviously increase the survival time and decrease the level of TNF-?. After ALL junior mice transplatated,IL-11 could delay and relieve GVHD.Conclusion IL-11 can alleviate GVHD and retain the effect of GVL after allogenic bone marrow transplantation.

This paper presents a new kind of collecting and processing system of the sound signal of larynx where double sound cards and software filter are used. The installation of the double sound cards and processing proposal of software are mainly discussed and a new kind of ADC method of dual-channel sound signal is put forward in this paper. This system has the feature of reliable performance, simple installation and easy maintenance.

Objective: To study the effect of arsenic trioxide (As2O3) on human pancreatic cancer cell proliferation and apoptosis (mainly early stage) in vitro. Methods: SW1990 cells line were trea ted with As2O3 at different concentration. Cell proliferation was evaluated by MTT and apoptosis by Annexin-Ⅴ-fluostaining, electron-microscopy, flow cytometry and immunocytochemical staining of Bcl-2 and Bax. Results: As2O3 and cisplatin had the same cytotoxity on SW1990. The cytotoxic effe ct on tumor cell was produced by induction of apoptosis. Twelve hours after cult ure with 10 μg/ml As2O3, much more SW1990 cells went into apoptosis than t he control. The apoptosis rate reached 24% after 48 h with the similar concentra tion of As2O3. Immunohistochemical study revealed that the expression of Bcl -2 was decreased after treated with As2O3. Conclusion: As 2O3 can depress the proliferation of SW1990 in vitro, mainly through the i nduction of apoptosis, and it is a potential agent for pancreatic cancer chemoth erapy.

Objective To evaluate the significance of fiberoptic bronchoscopic brush cytology in the diagnosis and histological classification of lung carcinoma.Methods Data of 309 patients with lung carcinoma were retrospectively analyzed.Both bronchoscopic cytology and histology diagnosis were available.The positive rate of bronchoscopic cytology and tissue biopsy were calculated respectively.The classification accuracy of cytological diagnosis for lung carcinoma was evaluated.In tissue biopsy standard,evaluated the significance of bronchoscopic cytology in diagnosis and histological diagnosis.Results The positive rate of bronchoscopic cytology and tissue biopsy were 86.1% (266/309) and 83.8% (259/309),respectively.Bronchoscopic cytology combined with bronchial biopsy could obviously improve the positive rate to 94.2% (291/309) in lung carcinoma diagnosis.Taking the tissue biopsy histological type as a standard,the cytotyping accuracy for brush method was 85.1%(74/87) in squamous carcinoma,82.4%(108/131) in adenocarcinoma and 100%(11/11) in small cell carcinoma for higher.However,the accuracy in diagnosing poorly differentiated carcinomas was only 12.2% (5/ 41).Conclusion Fiberoptic bronchoscopic brush cytology plays an stable and important role in diagnosing lung carcinomas and histological type determination.However,it has limited use in diagnosing poorly differentiated carcinomas.
