Objective To investigate the influence of fishbone diagram in the incidence of blood residual after sealing tube indwelling needle in cardiovascular disease patients.Methods Two hundred and ninety-three patients(1,035 times)with sealing tube intravenous indwelling needle were assigned into control group and another 272 ones(1,276 times)with the needle into experiment group according to admission sequence. In the former group the method of conventionally sealing the tube for intravenous indwelling needle was applied and in the latter,fishbone diagram was applied to analyze the key factors for blood residuals and regulate pertinent measures for effective sealing of tube.The two groups were compared in terms of incidence of blood residuals.Result The incidence of blood residuals in the experiment group was significantly lower than that in the control group(P<0.05).Conclusion The fishbone diagram is effective in reducing the incidence of blood residuals after sealing the tube for intravenous indwelling needle by way of taking effective interventional measures after screening out the key influential factors for blood residuals.

In order to reveal the treatment mechanism of Chinese medicine with the effect of activating blood and resolving putridity, we selected acetyl-11-keto-beta-boswellic acid (AKBA) and arsenic trioxide (ATO), the main monomeric components of frankincense and arsenolite which are two most commonly used Chinese medicine with effect of activating blood and resolving putridity. We combined AKBA and ATO as a compound, and explored its regulatory role in productions and activities of matrix metalloproteinase (MMP)-1, MMP-2 and MMP-9 in human skin fibroblasts (HSFbs) and human acute monocytic leukemia cell line THP-1 in inflammatory state.

Background: Studies showed that aberrant activation of JAK/STAT3 signaling pathway promoted the tumorigenesis and progression of hepatocellular carcinoma (HCC), and transforming growth factor-β1 (TGF-β1) has either tumor-suppressing or tumor-promoting effect in regulation of tumor progression.Aims: To investigate the effect of specific inhibition of JAK/STAT3 signaling pathway on HCC and whether TGF-β1 signaling pathway is involved in this process or not.Methods: Thirty Wistar rats were randomly divided into three groups: control group, HCC group, and HCC+AG490 group.In the latter two groups, diethylnitrosamine was administered in drinking water to induce HCC model, and in HCC+AG490 group, AG490, a specific inhibitor of JAK was injected intraperitoneally in the first week of model establishment.At the end of the 16th week, all rats were sacrificed.The maximum diameter of tumor nodules in the liver was recorded and the number of tumors with maximum diameter greater than 1 cm was counted.Expression and distribution of STAT3 and TGF-β1 in liver tissue were determined by real-time PCR, immunohistochemistry, and immunofluorescence.Results: Compared with the control group, expressions of STAT3 and TGF-β1 mRNA in liver tissue were significantly increased in HCC group (P<0.05).Phosphorylated STAT3 (p-STAT3) and TGF-β1 proteins were absent in liver tissue in control group, and both were up-regulated and co-expressed in HCC group.While in HCC+AG490 group, expressions of STAT3 and TGF-β1 mRNA were significantly lower than those in HCC group (P<0.05);the liver tissue was weakly positive for p-STAT3 and TGF-β1 proteins, and the number of tumor nodules greater than 1 cm and the maximum diameter were markedly reduced when compared with the HCC group [1.20±1.03 and (1.14±0.18) cm vs.4.30±1.06 and (1.78±0.27) cm, P all<0.05].Conclusions: Specific inhibition of JAK/STAT3 signaling pathway may restrain the tumorigenesis and progression of HCC partially by interfering TGF-β1 signaling pathway.

Objective To compare the efficacy and resistance between S?1 combined with radiotherapy and S?1 alone in the treatment of elderly patients with locally advanced gastric cancer. Methods Fifty?eight elderly patients with unresectable locally advanced ( stage Ⅲ) gastric cancer were randomly and equally divided into S?1 combined with concurrent radiotherapy group ( experimental group ) and S?1 alone group ( control group ) . The experimental group received 4 cycles of S?1 treatment with each cycle containing two?week oral administration of S?1 at a dose of 40 mg/m2 twice a day followed by one?week drug withdrawal. Gastric intensity?modulated radiotherapy was performed concurrently with a dose of 45 Gy ( 1. 8 Gy per fraction) . The control group received the same dose of S?1 alone. Short?term outcomes and adverse reactions were evaluated in the two groups. Comparison was made by chi?square test. Results All patients completed the planning treatment. The experimental group had significantly higher objective response, disease control, and symptom remission rates than the control group ( 52% vs. 24%, P=0. 03;76% vs. 45%, P=0. 016;86% vs. 48%, P=0. 005) . There were no significant differences in the incidence of nausea and vomiting, anorexia, leukopenia, diarrhea, or thrombocytopenia between the two groups ( all P>0. 05) . Conclusions S?1 treatment combined with concurrent radiotherapy improves the short?term outcomes and causes tolerable toxicities in the treatment of elderly patients with locally advanced gastric cancer.

Objective To investigate the successful rate and the therapeutic effect of loosening posterior tubercle of cervical transverse process with CT-guided insertion or blind insertion of small needle knife for cervical spondylotic radiculopathy. Methods Ninety patients with cervical spondylotic radiculopathy were divided into CT-guided insertion group and blind insertion group in the admission order using the random number table method, 45 cases in each group. CT-guided insertion group adopted the insertion of small needle knife following by the guide of CT, and the blind insertion group adopted the insertion of small needle knife following by cervical bony landmarks and muscles. After insertion, the position of the small needle knife in patients of the two groups was located by CT scan. If the needle knife did not arrive to the foci, it will be inserted again following by the guide of CT till successful insertion and location. The successful rate for the two times of insertion was calculated, and the pain scores were evaluated by visual analogue scale(VAS). Results(1) The successful rate for the first insertion of CT-guided insertion group was 73.3％, and that of the blind insertion group was 47.8％, the difference being significant(P < 0.01). The successful rate for the second insertion of CT-guided insertion group was 92.2％, and that of the blind insertion group was 80.0％, the difference being significant (P<0.01). (2) After treatment for one week, pain VAS scores of the two group were decreased (P < 0.01 compared with those before treatment) , and the decrease in the CT-guided insertion group was more obvious than the blind insertion group (P < 0.05). Conclusion CT-guided insertion makes the small needle knife therapy be more accurate and safer, ensures much better therapeutic effect, and brings less pain in the patients.
