ABSTRACT
Objective To observe the efficacy of Chinese herbal fumigant sitz bath for different exposure durations on patients for the complicatiors after mixed hemorrhoidectomy.Methods One hundred and twenty patients with mixed hemorrhoidectomy were randomized into four groups(2 treatment groups and 2 control groups) with 30 cases in each group.The treatment groups were treated with the Chinese Herbal fumigant sitz bath for 10 minutes and 15 minutes respectively;while the control groups were treated with the hemorrhoids lotion for 10 minutes and 15 minutes respectively.The severity of pain,edema,bleeding,constipation and urinary disturbance were scored on the second,seventh and fourteenth days after treatment.Data were analyzed statistically.Results Chinese herbal fumigant Sitz baths for 10 minutes could significantly reduce postoperative pain,edema and bleeding symptoms[(1.72±1.23) points,(0.72±1.25) points,(0.91±1.37) points,respectively,P ＜0.05],followed sequentially by groups of Chinese herbal fumigant Sitz baths for 15 minutes [(1.79±1.21)points,(0.89±1.28) points,(1.03±1.24) points]; The hemorrhoids lotion for 10 minutes ((1.86±1.25) points,(1.14±1.47) points,(1.49±1.56)) and 15 minutes[(2.03±1.48) points,(1.05±1.29) points,(1.39±1.47) points,respectively,P ＜ 0.05]With the successful cases of 27,21,18,and 6 in the groups,respectively.Though the overall response rates of for the groups of 10 min's treatment,15min's treatment and 10 min's control were not significantly different between each other(P =0.0634,P =0.2560),they showed a superior efficacy in the overall response rate to the 15 min's control group(P =0.0064,P =0.0365,P =0.0089),respectively.Conclusion Chinese herbal fumigant Sitz baths for 10minutes have a success rate of 100％ on alleviating complications after mixed hemorrhoidectomy.It has a prominent efficacy on reducing postoperative edema and bleeding symptoms than other treatments studied in this program.
ABSTRACT
Aberrations of the mammalian target of rapamycin (mTOR) signaling are frequently observed in many types of cancer.Activation of mTOR regulates tumor cell proliferation,survival and metastasis,and then results tumorigenesis and tumor developmet.Blocking the mTOR signaling pathway by rapamycin and its derivatives can inhibit gastric cancer cell growth and promote tumor necrosis and such effects can be synergistically improved by combined use of other chemotherapeutic agents.Thus,rapamyein and its derivatives may be effective in the prevention and treatment of gastric cancer.
ABSTRACT
Objective To summarize our experience in choledochofiberscopic treatment for residual stones of biliary tract. Methods 1105 cases of residual stones of biliary tract diagnosed and treated with choledochofiberscope in the past 19 years were reviewed retrospectively. Results The 1067 patients with residual stones of bile duct were treated with choledochofiberscope for 1483 times altogether. The stones were completely removed in 1035 cases, while the stones were not cleared in other 32 cases. The clearance rate of residual stones was 97.0%(1035/1067). No patient died of choledochofiberscopic treatment. Conclusions Choledochofiberscopic treatment plays an important role in the treatment of residual stones of bile duct, because it not only reduces residual stones of bile duct to avoid repeated operation, but also has some advantages such as excellent safety, minimal invasion, low cost and quicker recovery.
ABSTRACT
Objective To study the relationship between lymph node micrometastasis and clinicopathological parameters. Methods Immunohistochemical method was adopted to detect CK19,CK20 and CD44v6 in 509 lymph nodes from 53 cases of gastric cancer, in which, conventional pathological diagnosis showed no lymph node metastasis. Results Micrometastasis was found in 47 lymph nodes (9.2%) of 21cases ( 39.6 %). The incidence of micrometastasis was correlated with the depth of invasion, and the incidence of micrometastasis in PT 3 and PT 4 patients was more than that in PT 1 and PT 2 patients(P
ABSTRACT
AIM: To investigate p16 gene alterations in gastric carcinoma. METHODS: 36 fresh tumor specimens taken from gastric cancer patients were analyzed for p16 gene deletion and mutation by polymerase chain reaction (PCR) and DNA sequencing. RESULTS: Homozygous deletion of exon 1 and exon 3 was observed in 2 cases and 3 cases of diffuse carcinoma, respectively. The frequency of homozygous deletion was 13.89%. No p16 gene point mutation was detected. CONCLUSION: The deletion of p16 genes may be related to gastric carcinogenesis.
