Objective Evaluate the feasibility of PTCA and stents by radial artery. Methods we had operated PTCA for 25 cases by radial artery from July 2004 to April 2005. The average age is 63 years old including 40 men and 15 women. Results 67 stents were implanted in 55 patients including 30A cases, 26 B cases and 11C cases. These stents is about 8mm to 33mm in length and 2.5mm to 4.0mm in width. The successful rate is 96%(53/55), and two case was failed, because the guiding wire can not pass by chronic obstruction in LAD all. There is no case by femoral. All the procedures have no heart complications, obstruction of radial artery and vascular complications. Conclusions The way is good for PTCA by radial artery. Its advantages are mild injury, high successful rate and few complications, and the salted hospitals can use the technology successfully.

Chemotherapy completion rate can reflect the tolerance and compliance of patients to chemotherapy. Poor tolerance may result in delay or suspension of the comprehensive treatment plan, thus affect the efficacy of cancer treatment. Evaluating methods to improve the completion rate of chemotherapy and reduce the occurrence of delayed chemotherapy has gained increasing attention and is the significant area of study in the field of cancer treatment. Studies have shown that Chinese medicine combined with chemotherapy could improve the quality of life in patients with stage IIIB/IV non-small-cell lung cancer (NSCLC).

BACKGROUNDLentinus edodes polysaccharide (Lentinan) has attracted great attention from both pharmacologists and clinicians as a biological response modifier, and is widely used as an anti-tumor agent in both China and Japan. The aim of this study is to observe the efficacy of Lentinan combined with chemotherapy in stage III-IV non-small cell lung cancer (NSCLC).

METHODSEighty-one patients with stage III-IV NSCLC were randomly divided into two groups: (1)Lentinan + chemotherapy group (group A, 42 cases); (2)Simple chemotherapy group (group B, 39 cases). The peripheral blood T lymphocyte subsets (CD3, CD4, CD4/CD8) and natural killer (NK) cell activity of patients in both groups were measured before and after treatment, while compared with healthy control (30 cases). The immune functions, the effect of treatment, quality of life, and adverse reactions were observed.

RESULTSAfter treatment the objective response rate (CR+PR) was 50% in group A, compared to 33% in group B (P < 0.05). The blood T cell levels(CD3, CD4, CD4/CD8) and NK cell activity in group A increased (P < 0.01), CD8 reduced (P < 0.05), but in group B the value had no obvious change (P > 0.05). Quality of life in group A was higher than that in group B (P < 0.01). The incidence of grade II-IV leukopenia, nausea and vomiting in group B was much higher than those in group A (P < 0.05).

CONCLUSIONSThe therapeutic effect of Lentinan combined with chemotherapy is better than that of chemotherapy alone.

OBJECTIVETo compare the clinical efficacy on chronic pelvic inflammation between the acupoint embedding therapy and acupuncture, and to compare the efficacy of different patterns/syndroms in differentiation treated with acupoint embedding therapy.

METHODSTwo hundred and eighteen cases were randomized into an embedding therapy group (115 cases) and an acupuncture group (103 cases). In both groups, Shenshu (BL 23), Guanyuanshu (BL 26), Zigong (EX-CA 1), Yaoyangguan (GV 3), Guanyuan (CV 4) and Qihai (CV 6) were selected as the main points. For qi and blood stagnation pattern/syndrome, Zhongdu (LR 6), Diji (SP 8) and the others were added; for cold and damp stagnation pattern/syndrome, Diji (SP 8) and Sanyinjiao (SP 6) were added; for stasis and phlegm pattern/syndrome due to spleen deficiency, Sanyinjiao (SP 6) and Zusanli (ST 36) were added. In the embedding therapy group, the catgut was embedded at 7 - 13 acupoints each time, once every 10 days. In the acupuncture group, the conventional acupuncture therapy was applied, once a day. The symptom scores were assessed in the aspects of the lower abdominal pain severity and attack frequency, lumbosacral soreness and distention, abnormality of vaginal discharge and the others. The efficacy was compared between the two groups.

RESULTSThe total effective rate was 93.0% (107/115) in the embedding therapy group, which was better than 83.5% (86/103) in the acupuncture group (P < 0.05). The symptom scores were all reduced after treatment in the two groups (all P < 0.05). In the embedding therapy group, the efficacies were not significantly different among different patterns/syndromes (all P > 0.05).

CONCLUSIONThe acupoint embedding therapy achieves the definite efficacy on chronic pelvic inflammation and obtains the similar efficacies among the different differentiated patterns/syndromes of the disease.

Recently the maintenance therapy of non-small-cell lung cancer (NSCLC) patients who completed required treatment cycles has caused widespread interests in the medical field. Traditional Chinese medicine may be a useful complement in maintenance treatment of mid-to-late stage NSCLC.

AIM: To analyze the changes of retinal structure and function before and after panretinal photocoagulation(PRP)in patients with proliferative diabetic retinopathy(PDR).METHODS: Prospective study. Totally 98 cases(98 eyes)of PDR patients who underwent PRP in Eye Hospital of Wenzhou Medical University from January 2022 to May 2023 were included. Optical coherence tomography angiography(OCTA)was used to detect central retinal thickness(CRT), central macular thickness(CMT), subfoveal choroidal thickness(SFCT), foveal avascular zone(FAZ), deep vascular complex(DVC)blood flow density, superficial vascular complex(SVC)blood flow density before and at 1 wk, 1 and 3 mo after PRP. During the follow-up, 1 eye underwent vitrectomy, 2 eyes were lost to follow-up, and finally 95 eyes completed 1 a follow-up, with a loss rate of 3%. According to the visual prognosis at 1 a after treatment, the patients were divided into two groups: 73 eyes in good prognosis group and 22 eyes in poor prognosis group(including 9 eyes of visual disability and 13 eyes of visual regression). The changes in retinal structure and function before and after PRP treatment were compared between the two groups of patients, and the receiver operating characteristic(ROC)curve and decision curve were used to analyze the predictive value of retinal structure and function for PDR treatment.RESULTS: There were statistical significant differences in PDR staging, CRT, CMT, SFCT, DVC blood flow density, and SVC blood flow density between the two groups of patients before treatment(all P<0.05). At 1 wk, 1 and 3 mo after treatment, the FAZ area of both groups decreased compared to before treatment, while the blood flow density of DVC and SVC increased compared to before treatment(both P<0.05). However, there was no significant difference in the blood flow density of FAZ, DVC, and SVC between the two groups at 1 wk, 1 and 3 mo after treatment(all P>0.05). The CRT, CMT and SFCT of the two groups at 1 wk after treatment were higher than those before treatment(all P<0.05), but there were no significant differences between the two groups(all P>0.05). The CRT, CMT and SFCT at 1 and 3 mo after treatment were lower than those at 1 wk after treatment and before treatment in both groups. The CRT, CMT and SFCT in the poor prognosis group at 3 mo after treatment were higher than those at 1 mo after treatment, and were higher than those in the good prognosis group(all P<0.05). ROC analysis showed that, at 3 mo after laser treatment in PDR patients, the area under the curve of the CRT, CMT, and SFCT alone or in combination after treatment for 1 a was 0.788, 0.781, 0.783, and 0.902, respectively, and the combined prediction value was better(P<0.05). Decision curve analysis showed that the combined detection of CRT, CMT, and SFCT in PDR patients at 3 mo after treatment can improve the predictive value of visual prognosis.CONCLUSION: The optimal time for retinal structure and function recovery in PDR patients after PRP treatment is between 1 wk and 1 mo. OCTA measurement of CRT, CMT, and SFCT at 3 mo after treatment can predict the visual prognosis during the 1 a treatment period.

Objective To detect the association between rs4646999 polymorphisms in the promoter region of the c-Jun and the prognosis of sporadic colorectal cancer. Methods rs4646999-673C>T genetypes were deter-mined by Taqman-MGB probes in 436 colorectal cancer cases. The survival curve was analyzed by Kaplan-Meier analysis and Cox regression.Western blot was used to analyze the expression levels of c-Jun protein in different gen-otypes. Results Univariate analysis showed that the cumulative survival rate of patients with rs4646999TT geno-type was significantly higher than that of patients with CT and CC genotype. Multivariate Cox regression analysis showed that the differentiation,lymph node metastasis,distant metastasis,TNM stage and rs4646999 genetypes were prognostic factors.Compared with the carriers of TT genotype,CT/CC complex genotypes were associated with poor prognosis of colorectal cancer(P<0.05).Protein expression analysis showed that the expression of c-Jun pro-tein in CC genotype was increased.In contrast,the TT genotype was decreased.Conclusions This study provided the evidence that rs4646999-673C>T genetic variant in c-Jun promoter regions is associated with the poor survival prognosis of colorectal cancer,possibly by elevating the protein expression levels that appeared to up-regulate activ-ity of c-Jun thus tumorigenesis.
