Objective To assess the clinical efficacy of fluoroscopically-guided percutaneous cholecystostomy in the treatment of severe acute cholecystitis and to summarize the experience in clinical practice. Methods During the period of Jan. 2006 -Dec. 2008,fluoroscopically-guided percutaneous cholecystostomy was performed in 31 patients with severe acute cholecystitis. The therapeutic results were evaluated by comparing the pre-operative and post-operative laboratory findings and clinical manifestations. Results The procedure of puncture and drainage-tube placement was successfully accomplished in all 31 cases without any complications. One patient with acute renal failure died after the procedure,the remaining 30 patients showed obvious alleviation of symptoms and were discharged with retention of the indwelling drainage-tube. Selective cholecystectomy was carried out in 16 patients with lithic cholecystitis in 1-3 months after percutaneous cholecystostomy. Living with retention of indwelling drainage-tube was chosen by eight patients with lithic cholecystitis. The drainage-tube was extracted in 6 patients with non-lithic cholecystitis in 3-6 weeks after the cholecystitis was cured. Conclusion Fluoroscopically-guided percutaneous cholecystostomy is technically-simple,minimally-invasive and highly-safe treatment for severe acute cholecystitis,it may be regarded as an effective transitive,or even permanent therapy.

Objective To explore the diagnostic value of conventional ultrasound(US) and contrast enhanced ultrasound(CEUS) in predicting extrathyroidal extension of papillary thyroid cancer(PTC).Methods Eighty-five PTCs in 75 patients were selected for thyroid surgery underwent ultrasound and contrast-enhanced ultrasound.The degrees of contact between PTCs and capsule were observed by US and CEUS respectively(0,0-25％,25％-50％,≥50％),and the diagnostic efficiency in different degree of contact (＞0 ％,≥25 ％,≥50％) as preoperative diagnostic criteria were analyzed.The diagnostic efficiency between US and CEUS in predicting extrathyroidal extension of PTC were compared.Results Of the 85 PTCs,extrathyroidal extension was presented in 57 (67.06％) based on pathologic results.When the degree of contact (＞ 0 ％,＜ 25 ％,25 ％-50 ％,≥ 50 ％) was gradually increased,the incidence of extrathyroidal extension of the thyroid cancer was also gradually risen (P ＜0.001).Comparing the sensitivity,accuracy,odds ratio,and Az value of three groups(＞0％,≥25％,≥50％),it showed that the general diagnostic efficiency between two groups(＞0％,≥25％) was similar by US and CEUS.However,the sensitivity and accuracy of ＞0％ contact with the adjacent capsule were markedly higher than those of the other two groups(P ＜0.001).Selecting ＞0％ contact with the adjacent capsule as preoperative criteria,the Az value of CEUS was markedly higher than that of US (Z =2.208,P =0.027).Conclusions The preoperative imaging feature of more than 0％ contact with the adjacent capsule is more sensitive and accurate degree in predicting extrathyroidal extension of PTC.Compared with US,CEUS may serve as a better useful tool to predict extrathyroidal extension of PTC.

Objective To investigate the effect of electroacupuncture on the rehabilitation of rheumatoid arthritis (RA) and level of nuclear factor-κB (NF-κB), tumor necrosis factor-α (TNF-α) and interleukin 1β (IL-1β). Methods 140 cases of RA meeting the inclusion criteria were divided into control group and observation group equally according to therapeutic schemes. All the patients accepted medicine and rehabilitation training, while the observation group accepted electroacupuncture in addition. The effective rate and the symptoms were observed, the serum level of rheumatoid factor (RF), antistreptolysin O antibody (ASO), C-reactive protein (CRP), NF-κB, TNF-α and IL-1β were tested before and after treatment. Results The effective rate was 92.8% in the observation group, which was significantly more than that of 80.0% in the control group (P<0.05). The joint pain index, joint tenderness index and joint swollenness index reduced in the observation group compared with those in the control group (P<0.05), as well as the serum level of RF, ASO, CRP, NF-κB, TNF-α and IL-1β (P< 0.05). Conclusion Electroacupuncture may improve the effects of rehabilitation training for RA and inhibit the inflammation, which may associate with the inhibition of activation of NF-κB.

The composition of volatile compounds of soils and that of soil bacterial metabolites were identified by using the SPME-GC/MS method. Results showed that some compounds, trimethylamine, 3-methyl-2-pentanoe, dimethyl disulfide, methyl pyrazine, 2,5-dimethyl-pyrazine, benzaldehyde, N,N-dimethyloctylamine and nonadecane, subsisted commonly in soils and soil bacterial metabolites with strong fungistatic activity. These compounds may be the key antifungal factors in soil fungistasis, especially soil volatile fungistasis. Otherwise, the method used in this study was a good tool for further study of soil volatle fungistasis.

Objective To investigate the effect of acupunctures variable with stages on lumbar intervertebral dise protrusion (LIDP). Methods 98 LIDP patients in our hospital from October, 2014 to July, 2015 were randomly divided into control group (n=49) and observa-tion group (n=49) according to the sequence of first diagnosis time. The control group received routine acupuncture, and the observation group acupunctured at Ouch point and Huantiao point (GB30) with different acupuncture according to manifestations and courses. Modified Yang acupuncture was adopted in acute phase, triple acupuncture was used in remittent phase, and lateral needling was used in the recovery phase. They were both treated once a day, 7 days as a course for 3 courses with 2 days of interval. Visual Analogue Scale (VAS), Oswestry Disability Index (ODI) and clinical effects were assessed before and 1, 2, 3 courses after treatment. Results Both VAS and ODI scores im-proved after treatment (F>7.12, P<0.05), especially in the observation group (t>4.43, P<0.05). The efficiency was higher in the observation group than in the control group (χ2=5.594, P<0.05). Conclusion Compared with normal acupuncture, the acupunctures variable with stages is more effective on LIDP than routine.

OBJECTIVETo observe the effect of Weichang'an (WCA, a Chinese preparation) in preventing post-operative metastasis of progressive stage of gastric cancer.

METHODSA prospective randomized, controlled study was conducted by dividing the 148 patients of progressive staged gastric cancer after radical operation into the WCA group, the chemotherapy (CT) group and the WCA + CT group, to observe the survival rate, metastasis rate, quality of life (QOF) and tumor-bearing survival time after relapse (TST) in patients.

RESULTSThe 1-, 2- and 3-year survival rate after operation in the WCA + CT group was 89.51%, 69.77% and 55.76% respectively, which was significantly higher than that in the CT group (83.86%, 59.33% and 49.43%) respectively (P < 0.05), but showed insignificant difference as compared with that in the WCA group (93.23%, 79.34% and 71.78%). Only 1-year metastasis in the WCA group was 15.25%, and in the WCA + CT group was 15.52%, the two were significantly lower than that in the CT group (35.48%, P < 0.05). But the comparison of 2-year metastasis rate among the 3 groups (28.81%, 41.38% and 45.16%) and 3-year metastasis rate among them (33.90%, 46.55% and 51.61%) were insignificantly different. The QOF and TST were markedly better in the WCA group than those in the CT group.

CONCLUSIONWCA has preventive effect on relapse and metastasis in post-operational gastric cancer patients.
