120 cases were treated by microlaryngoscopic surgery alone from March to December 1985. Among them, 73 cases were polypoid cord, 28 cases vocal cord nodule, and 19 cases of other conditions. The immediate curative results were good in 114 cases, 5 cases fair and only 1 case was poor. The postoperative complications are: dentes primoris moving in 2 cases and aerodermectasia in 1 case. The operation method is very satisfactory through an endotracheal tube without laryngeal injury. It can accomplish the unsuccessful operation done by mirior, direct and fibrous laryngoscopy surgery. The patients were under general anesthesia by an endotracheal tube without any pain or anxiety and can obtain good relaxation. The authors wish to recommend this technique to treat the related laryngeal disease.

From 1982 to 1988, we have performed supraglottic horizontal partial laryngectomy for 41 cases of laryngeal carcinoma. 19 of them were males and 22 females. 40 cases of squamous cell carcinoma accounted for 97.6%,and 75.6% of cases were in second or third stage. All the cases have been followed up. The three-year survival rate is 93.7%, the five-year survival rate is 86.5%. 95% of the patients retained their phonation ability. Decannulation rate of tracheostomy tube is 65.9%. Normal deglutition ability is found in 90.2% of cases. Indications for operation, postoperative complications, late results, and failure of removal of tracheostomy tube are discussed.

Objective To study the prevalence and the related risk factors of diabetic peripheral neuropathy(DPN) after good blood glucose well controlled among in middle-aged and old-aged population with type 2 diabetes mellitus in a community of Beijing.Methods DPN was screened by Michigan neuropathy screening instrument (MNSI),and common blood biochemical parameters were tested,among over 45 years of age registered population patients with type 2 diabetes mellitus in Shuangjing community of Chaoyang District of Beijing.Results The blood glucose control rate was 90.36％ (253/280),and the prevalence of DPN was 25.36％ (71/280) with male of 24.47 ％ (23/94) and female of 25.81％ (48/186).Univariate analysis showed that both age and HbA1c in DPN group were higher than that of non-DPN group,and the differences were statistically significant(P =0.000,0.008).The level of plasma low density lipoprotein cholesterol(LDL-C) of the DPN group was lower than that of the non-DPN group,and the difference was statistically significant (P=0.017).The hypertension prevalence rate of the DPN group was 87.32％(62/71),higher than that of the nonDPN group(75.6％ (158/209)),and the difference was statistically significant (P =0.037).The multivariate logistic regression analysis showed that the estimate of parameter for age was 0.143 (P =0.0001),OR was 1.153,95％CI was from 1.029 to 1.219,for HbA1c was 0.529(P=0.03),OR was 1.698,95％CI was from 1.053 to 2.738,and for LDL-C was-O.919 (P =0.018),OR was 0.399,95％ CI was from 0.186 to 0.854.Conclusion The prevalence of DPN is still above 25％ among middle-aged and old-aged in a community,even though the well controlled rate of blood glucose control rate is above 90％.It is possible that old age and HbA1c are related to DPN,apart from blood glucose.

Objective To evaluate the effect of nurse-led follow-up on medication adherence and quality of life for breast cancer patients receiving adjuvant hormonal therapy.Methods A randomized controlled trial was conducted with 157 patients in the intervention group and 154 in the control group.A self-design web-database medication monitoring platform was designed for managing patients such as texting,reminding and mailing.Participants were randomized to follow-up care as usual(yearly outpatient clinic visits) or nurse-led telephone follow-up(monthly consultation with structured intervention).Telephone follow-up was performed by four trained breast care nurses (BCN) and consisted of a semi-structured interview including managing the side-effects of endocrine therapy,compliance with hormonal therapy and an open discussion of these issues.Patients' medication adherence and quality of life were evaluated by Morisky Medication Adherence Questionnaire(MAQ) and FACT-B at baseline and 3,6 18 and 24 months,respectively.Results The Nurse-led telephone follow-up did not significantly improve the quality of life(P＞0.05).MAQ score in the intervention group was significantly greater than that in the control group(P＜0.05) at 3,6,18 and 24 months.Conclusion Nurse-led follow-up using computer-based monitoring system can improve patients' medication adherence,but there is no obvious increase in quality of life.

Objective To investigate relationship of platelet (PLT) count with clinicopathological features and prognosis of patients with breast cancer,and explore the susceptibility index to evaluate prognosis of patients with breast cancer.Methods A retrospective analysis of clinical data of 498 patients with breast cancer in January 1995 to December 2005 was carried out.PLT count was tested.Those patients were divided into group A (PLT ＜ 150 × 109/L),group B[(150-250) × 109/L],and group C (PLT ＞ 250 × 109/L) according to PLT count level.The relationship of platelet count with clinicopathological features was analyzed.Kaplan-Meier and Cox proportional hazards model were used for univariate analysis and multivariate analysis of PLT impact on survival time.Results There was positively correlated between PLT count and clinicopathological features (Pearson coefficient ＞ 0,P ＜ 0.05).There was negative correlated between PLT count and survival time (Pearson coefficient =-O.583,P ＜ 0.05).The survival time of groups A,B and C were significantly different (P =0.018).Cox proportional hazards model multi-factor analysis showed that PLT count was an independent factors affecting survival time (OR =2.256,P ＜ 0.05).Conclusions Patients with breast cancer associated with increased emphasis and PLT count.PLT count had negative correlation with survival time.PLT count could be a susceptible index to predict the prognosis of patients with breast cancer.

Lung cancer is one of the most common malignancies. Anti-tumor drugs with intravenous administration have systemic adverse effects as well as limited efficacy. Drugs can concentrate in lungs after pulmonary administration,which limits the distribution in the other organs and reduces the side effects of anti-tumor drugs. The paper focused on the recent progress in the studies on new dos-age forms of anti-tumor drugs for pulmonary administration for the therapy of lung cancer,so as to provide reference for the development of anti-tumor drugs for pulmonary administration.

Objective:To investigate the efficacy of β-elemene combined with gefitinib in the treatment of advanced lung adenocarcinoma patients with slow progression after first-line gefitinib treatment and its effects on quality of life and immune function.Methods:A prospective cohort study design was used to enroll patients with advanced lung adenocarcinoma who met the inclusion criteria from June 2017 to December 2018 in our hospital. They were divided into experimental group and control group by random number table method. The experimental group was given elemene combined with gefitinib, and the control group was only given gefitinib. The clinical efficacy, quality of life and immune function of the two groups were compared after 2 cycles of treatment. The PFS2 (time from slow progression of disease to rapid progression of disease) was followed up.Results:A total of 61 patients were included. There were 30 cases in the experimental group and 31 cases in the control group. The disease control rates of the experimental group and the control group were 83.3% (25/30) and 58.1% (18/31) respectively, and the difference was statistically significant ( χ2=4.680, P=0.031). The short-term efficacy of the experimental group was better than that of the control group, and the difference was statistically significant ( Z=-2.623, P=0.009). The median PFS2 of the experimental group was 4.20 months (95% CI: 3.94-4.46), and the median PFS2 of the control group was 4.00 months (95% CI: 2.94-5.07), with a statistically significant difference ( χ2=4.948, P=0.026). Quality of life was compared between the two groups: in terms of physical function, emotional function and overall quality of life, score differences before and after treatment of the experimental group were higher than those of the control group, with statistically significant differences [6.67(-6.66, 20.00) vs. 0(-6.66, 6.66), Z=-2.429, P=0.015; 29.17(2.08, 56.26) vs. 12.49(-14.59, 39.57), Z=-2.263, P=0.024; 16.67(-33.33, 56.67) vs. 8.34(-18.74, 35.42), Z=-2.249, P=0.025]. In terms of immune function, CD4 + T cells level in the experimental group increased after treatment compared with that before treatment (44.27%±6.78% vs. 41.17%±3.73%, t=-2.426, P=0.022), and CD8 + T cells level decreased compared with that before treatment (21.47%±3.18% vs. 23.50%±2.37%, t=2.532, P=0.017). After treatment, the level of CD4 + T cells in the experimental group was significantly higher than that in the control group (44.27%±6.78% vs. 39.63%±5.80%, t=2.725, P=0.011). Conclusion:β-elemene combined with gefitinib has a certain effect in the treatment of advanced lung adenocarcinoma patients with slow progression after first-line gefitinib treatment, and the quality of life and immune function are improved. It is worthy of further clinical research.
