Objective To investigate the expression of CD4+CDhi25CDlow127 regulatory T cells (Treg cell), IL-2, IL-10 and IFN-γin peripheral blood of patients with different TNM stages of non-small cell lung cancer( NSCLC) , and to evaluate their correlation. Methods The proportion of CD4+CDhi25 CDlow127 Treg cells to CD4+cell in peripheral blood of 55 NSCLC patients were determined by flow cytometry, and levels of IL-2, IL-10 and IFN-γ were measured by ELISA. The proportion of CD4+CDhi25 CDlow127 Treg cells, IL-2, IL-10 and IFN-γ of patients with different TNM stages of NSCLC were compared, and correlation analysis was carried on. Results The proportion of CD4+CDhi25 CDlow127 Treg cells increased obviously together with the increasing of TNM stages of NSCLC(P<0. 05),so did the level of IL-10 (P<0. 05). On the other hand, the level of IL-2 and IFN-γdecreased apparently with the increasing of TNM sta-ges of NSCLC(P<0. 05). CD4+CDhi25CDlow127Treg cells and IL-10 were positively correlated(P <0. 05). IL-2 and IFN-γ were positively correlated too(P<0. 05). CD4+CDhi25CDlow127Treg cells and IL-10 were all negatively correlated with IL-2 and IFN-γ(P<0. 05). Conclusion The increasing of CD4+ CDhi25CDlow127Treg cells and IL-10 and the de-creasing of IL-2 and IFN-γ are possibly one of the reasons of antitumor immunity suppression in terminal NSCLC patients. The surveillance for them can be reference indicators to evaluate antitumor immunity status of terminal lung cancer patients.

OBJECTIVE:To explore the effect of alendronte sodium and vitamin D3 on the T cell immune indexes in patients with different genders and ages with advanced lung cancer. METHODS:76 patients with advanced lung cancer were divided into non-small cell lung cancer(NSCLC)group(n=40)and small cell lung cancer(SCLC)group(n=36),and another 38 healthy vol-unteers were control group. Based on palliative care,all patients received Alendronte sodium and vitamin D3 tablet 1 tablet,po,qd, for 1 month. T cell immune indexes(CD4+,CD8+and Treg levels)in 2 groups before and after treatment,and when volunteers enroll-ing the control group were compared;and the incidence of adverse reactions were observed. RESULTS:Compared with control group,there were significant differences in CD4+,CD8+,CD4+/CD8+and Treg levels(P<0.05);but there was no significant differ-ence between NSCLC group and SCLC group(P>0.05). After treatment,CD4+ and CD4+/CD8+ levels in NSCLC group and SCLC group increased,changes of male were greater than female,CD8+and Treg levels decreased,changes of male were greater than fe-male,except for CD8+ level in NSCLC group (P=0.33),there were significant differences in others (P<0.05);CD4+ and CD4+/CD8+ levels in patients ≤50 years old increased more than patients >50 years old,CD8+ and Treg levels decreased more than pa-tients >50 years old,the differences were statistically significant (P<0.05). No obvious adverse reactions were found. CONCLU-SIONS:Alendronte sodium and vitamin D3 can effectively improve the T cell immune indexes in patients with advanced lung cancer, especially for male and patients≤50 years old,which can be considered as conventional adjuvant drugs for patients with lung cancer.

This study was aimed to establish an effective method for the simultaneous content determination of strychnine and brucine in rat plasma.The Wistar rat plasma samples were processed by liquid-liquid extraction and separated on a UPLC BEH C18 column.The mobile phase was acetonitrile - acid water (17?83).The acid water was 0.02 mol·L-1.The potassium dihydrogen phosphate and 0.014 8 mol·L-1 sodium heptane sulfonate was mixed with equal amount.The 10% phosphonic acid was used to adjust the system to the pH of 2.8.The detection wavelength was set at 260 nm.The results showed that foreign materials in the Wistar rat plasma did not interfere with the content determination of samples.The calibration curve of strychnine was in good linearity within the range of 0.067 84-3.392 00μg·mL-1.The calibration curve of brucine was in good linearity with the range of 0.052 48-2.624 00μg·mL-1.The intra-and inter-day precisions were less than 10%.The mean extraction recoveries were more than 85%.The stability results met the requirements for biopharmaceutical analysis.It was concluded that the UPLC detection method was sensitive and precise,which can be used in the pharmacokinetics study of strychnine and brucine in Tong-Mai(TM) pill.

objective To explore a new method of repairing skin defects complicated with fracture and tendon rupture at the middle and distal sections of the second to fifth fingers. Methods The reversed dorsal metacarpal island flap was designed to be pedicled on the digital proper artery-common digital artery-fingerweb artery-dorsal metacarpal artery-cutaneous branch of dorsal metacarpal artery.In repairing digital palmar skin defects,after the flap was dissected,the proximal incision was extended along the direction of dorsal metacarpal nerve to harvest an enough length of the nerve so that the dorsal metacrppal nerve can be anastomosed with the digital proper nerve to restore the sensation of finger pulp.From the June 2003 to March 2009,the flap was used to repair 26 fingers in 24 patients with middle and distal digital skin defects complicated with fracture and tendon rupture.They were 17 men and 7 women,aged from 16 to 63 years (average,37 years).There were 15 cases of palmar skin defect and 9 cases of dorsal skin defect.In the 2 cases of combined tendon defects,a section of the extensor tendon of index(or little) finger was dissected together with the flap to repair the tendon rupture. Results The areas of the flap ranged from 3.1 cm ×1.6 cm to 6.0 cm × 4.0 cm.The flaps survived in all 24 cases without any vascular crisis.Twenty-two patients obtained an average follow-up of 14 months (from 4 to 32 months) but 2 were lost to the follow-up.The flaps were fine in texture,colour and appearance.The finger pulps appeared full and recovered sensations of pain and temperature.The average two-point discrimination was 7.5 mm (from 5 to 9 mm).Sensory function evaluation revealed an outcome of S3 + ～ S4.Tendon adhesion occurred in 4 cases which recovered digital function following secondary lysis 3 to 6 months postoperation. Conclusion Application of the reversed dorsal metacarpal island flap pedicled on the digital proper artery is a good way to repair skin defects complicated with fracture and tendon rupture at the middle and distal sections of the second to fifth fingers.

Results: All incisions healed by first intention. Ten cases of thumb reimplantation were successful. All the patients were followed up for 5 months to 2 years and 8 months, with an average of 1 year and 4 months. Two-point discrimination was 3-9 mm (mean, 6.8 mm). According to Society of Hand Surgery standard for the evaluation of upper part of the function, the sensory of the thumb was rated as S 4 in 18 cases and S3+ in 5 cases; the sensory at donor sites recovered to S3. Conclusion Transferring the ulnaris proper digital nerve of index finger and its dorsal branch to repair the thumb nerve avulsion is a simple and effective method to restore sensory function of the thumb pulp.
