3.Clinical observation on every 3-week oxaliplatin plus 5-FU/CF regimen as postoperative adjuvant chemotherapy for colorectal cancer
Tumor 2009;(12):1167-1169
Objective:To investigate the clinical efficacy of every 3-week regimen of oxaliplatin (OXA) plus 5-fluorouracil (5-FU)/leucovorin(CF)as postoperative adjuvant chemotherapy for colorectal cancer.Methods:Ninety eight patients with stage Ⅱ to stage Ⅲ colorectal cancer received every 3-week OXA plus 5-FU/CF adjuvant chemotherapy for six cycles after resection surgery. All the patients received a complete reexamination every 3 months after the end of adjuvant chemotherapy. The disease-free survival period and 1- and 2-year disease-free survival rates were observed.Results:The total 2-year disease-free survival rate was 74.5%. It was 87.0% for stageⅡpatients and 63.5% for stage Ⅲ patients. The main adverse reaction included peripheral neurotoxicity, neutropenia and diarrhea at grades Ⅰ to Ⅱ. Grades Ⅲ to Ⅳ adverse reactions occurred rarely.Conclusion:The every 3-week OXA combined with 5-FU/CF adjuvant chemotherapy regimen had definite efficacy and good tolerance, which was a rational choice of postoperative adjuvant chemotherapy for colorectal cancer.

Microbial selective side-chain degradation of phytosterol,which can obtain the steroid medicine intermediate compounds-androst-4-ene-3,17-dione (4-AD) and androsta-1,4-diene-3,17-dione (ADD),has an important meaning to pharmacy. There is no systematic literature concerned in existence. Its mechnism,approaches,influencing factors and so on over these years were fully reviewed in the paper. The trend of development in the area is expanded.

Chinese Journal of Current Advances in General Surgery 2017;20(2):105-109
Objective:To study the expression and clinical significance of GPRC5A and SOCS3 in colorectal carcinoma.Methods:SP immunochemical method was performed to detect the expression of GPRCSA and SOCS3 in 45 cases of colorectal carcinoma,25 cases of colorectal adenomas and 22 cases of normal colorectal tissues.Results:1)Expression of GPRC5A in colorectal cancinoma tissue (22.2%) was significantly lower than that in adenomas tissue (52.0%,P>0.05).The Latter was significantly lower than that in normal colorectal tissue (81.8%,P<0.05).GPRC5Awas closely related to lymph node metastasis,Duke's stages and the deepness of invasion (P<0.05).2) Expression of SOCS3 in colorectal cancinoma tissue (24.4%) was significantly lower than that in adenomas tissue (56.0%,P<0.01).The Latter was significantly lower than that in normal colorectal tissue (86.4%,P<0.05).SOCS3 was closely related to pathological differentiation,the deepness of invasion,Duke's stages and lymph node metastasis (P<0.05).3)The expression of GPRC5A was positive correlated with SOCS3 (P<0.05).Conclusions:The reduced expressions of GPRC5A and SOCS3 may participate in the occurence and development of colorectal carcinorma,suggesting that GPRC5A and SOCS3 may act as biological markers for evaluating the malign degree,prognosis and therapeutic targets of colorectal carcinorma.

Objective To study the relationship of lung function and the diaphragmatic nerve electrophysiological changes in elderly patients with chronic obstructive pulmonary disease(COPD).Methods The phrenic nerve motor conduction(PNC),diaphragmatic motor evoked potentials(dMEP)and diaphragmatic compound muscle action potentials(dCMAP)were detected in 50 COPD patients and 50 healthy controls aged 60 years and over,respectively. Results (1)The lung function of elderly COPD patients were significantly less than that of control group(P0.05),the lower amplitude of dCMAP than the control(P

Objective To investigate the possible mechanisms of teratogenesis caused by passive smoking, temporospatial changes in surface carbohydrates of the embryonic neural epithelium and the mesenchyme around it were explored. Methods The pregnant golden hamsters were randomly divided into the treated group and the control groups. In the chamber made by ourself for passive smoking experiment, the animals of the treated group were exposed to smoke from embryonic day 4 to 7, 3 times per day for 4 consecutive days. At twelve o'clock and eighteen o'clock of embryonic day 8, eight o'clock of embryonic day 9 and eight o'clock of embryonic day 10 respectively, the pregnant golden hamsters of both treated group and control group were sacrificed, the uteri were removed and embedded routinely with paraffin, sectioned transversely in series. The sections of each group were stained with immunohistochemical ABC method and concannavalin agglutinin (ConA) and ulex europaeus agglutinin (UEA) were used as molecule probes to conduct the qualitative and quantitative analysis of the fibronectin and the related surface carbohydrates of the embryonic neural epithelium and the mesenchyme around it. Results During embryonic day 8 to10 of golden hamsters fibronectin reduced(F=30.168,P
9.Association of the Number of Negative Lymph Nodes with Prognosis of Post-operative Gastric Cancer Patients
Chinese Journal of Clinical Oncology 2010;37(2):101-103,107
Objective: To evaluate the impact of the number of negative lymph nodes on disease free survival (DFS) of patients with locally advanced gastric cancer. Methods: A total of 485 patients who underwent surgery for gastric cancer were enrolled in this study. We analyzed the data of these patients including complete information of follow-up and definite postoperative pathological results. The disease free survival of all patients was more than 6 months and was analyzed according to the pathological stage respectively. COX regression analysis was performed to screen the independent prognostic factors. Kaplan-Meier method was used to draw the disease free survival curve and the disease free survival rate was compared among subgroups. Results: Cox regression analysis showed that the disease free survival rate of gastric cancer patients with pathological stage T_3N_(0~2)M_0 was significantly associated with age, degree of tumor differentiation, tumor location as well as the number of negative lymph nodes. In the T_3N_0M_0 subgroup, when the number of negative lymph nodes was 1 to 4 and 5 or more, the 2-year disease free survival rate was 8.3% and 55.6%, respectively, and the 3-year disease free survival rate was 0 and 24.9%, respectively (P=0.025).In the T_3N_1M_0 subgroup, when the number of negative lymph nodes was 3 or less, 4 to 9, and 10 or more, the 2-year disease free survival rate was 17.3%, 39.1%, and 52.6%, respectively, and the 3-year disease free survival rate was 4.2%, 6.0%, and 17.1%, respectively (P<0.001). In the T_3N_1M_0 subgroup, when the number of negative lymph nodes was 7 or less and 8 or more, the 2-year disease free survival rate was 11.5% and 35%, respectively, and the 3-year disease free survival rate was 0.8% and 5%, respectively (P=0.015).Conclusion: For gastric cancer patients with pathological stage T_3N_(0~2)M_0, the number of negative nodes could reflect the level of regional lymph node dissection. The number of negative nodes can be an index for evaluation of the accuracy of pathological staging and is considered as an independent prognostic factor for disease free survival of gastric cancer patients.

Objective To observe angiogenic effect of platelet-released growth factors (PRGF) from platelet-rich plasma (PRP) on mierovessel formation at early stage after anterior crueiate ligament (ACL) reconstruction by freeze-dried Achilles tendon. Methods The study involved 14 rabbits, of which 12 rabbits were used as experiment group and the other 2 as control group. In the experiment group, after two sides of rabbit ACL were removed, freeze-dried Achilles tendon treated by PRGF was transplanted into random one side of the knee to substitute the original ACL (PRGF group), while the other side was transplanted with freeze-dried Achilles tendon treated only by normal saline (NS group). Only one side of the knee was removed in the control group. The grafts were observed by HE and immuno- histeehemical staining 2, 4 and 6 weeks after operation. Microvessel density (MVD) was measured by Weidner method. Results Compared with NS group, MVD in PRGF group was significant higher at 2,4 and 6 weeks after operation (P<0.05). MVD of NS group at 2,4 and 6 weeks after operation was 2.52±0.45, 3.41±0.44 and 2.57±0.51 respectively, but that of PRGF group at 2,4 and 6 weeks af- ter operation was 3.56±0.81,4.91±0.46 and 3.01±0.75 respectively (P<0.05). The time of neo- vascular formation and the depth of vascular penetration into the grafts of the PRGF group were superior to those of NS group. Conclusion PRGF can significantly promote microvessel formation at early stage after ACL reconstruction with freeze-dried Achilles tendon.
