Chinese Journal of Pathophysiology 1989;0(06):-
AIM: To study the effects of fructose-1,6-diphosphate (FDP) on adriamycin (ADR)-induced calcium and sarcoplasmic reticulum Ca 2+-ATPase activity in cardiomyocytes of rats. METHODS: Rats were treated with ADR by intraperitoneal injection (2 5 mg?kg -1 body weight) once every two days for 11 days, and then ADR-treated rats were intervened by FDP at different dosages (ip) once every other day for 41 days. Enzyme linked immune absorption assay (ELISA) was employed to detect froponin I (CTnI). CK-MB was examined by monoclonal antibody. Intracellular free calcium concentration was measured on fluorescent spectrophotometry and SRCa 2+-ATPase activity was examined by inorganic phosphate. RESULTS: FDP (300, 600, 1 200 mg?kg -1) significantly reduced the levels of CTnI and CK-MB in serum. Decreased calcium and increased SRCa 2+-ATPase activity in cardiomyocytes were also observed when ADR-treated rats were intervened by FDP (P

Journal of Chinese Physician 2001;0(05):-
Objective To explore the diagnostic value of transbronchial lung biopsy(TBLB), CT-guided percutaneous lung biopsy and sputum cytology for unknown lung mass. Methods The clinical data of 101 inpatients with unknown lung mass were retrospectively analyzed. Results Among the 101 cases, 73 cases underwent fibrous bronchoscopic examination, 18 cases underwent CT-guided percutaneous lung biopsy, and 10 cases underwent both of them.The diagnostic coincident rate of the two methods was 70%. 54 cases were diagnosed lung carcinoma by pathology. The sensitivity and specificity of TBLB for diagnosing central type of tumor were 88% and 100%, respectiely, and those for diagnosing peripheral type of tumor were 43% and 100%, respectively. The sensitivity of CT-guided percutaneous lung biopsy was 80%,while the specificity was 100%. Complication frequency in the CT-guided percutaneous lung biopsy was 22%, and much higher than that (12%) in the TBLB. Only 30% cases underwent sputum cytology examination, and the positive rat was 6%. Conclusion Sputum cytologic examination is a convenient and cheap method, but its diagnostic rate is relatively low. TBLB was the first choice for examining central type of lung mass. For the peripheral type of lung mass, examination method was selected based on the location and size of the mass.

Shanghai Journal of Acupuncture and Moxibustion 2015;(9):861-863
Objective To observe the clinical efficacy of acupuncture-moxibustion in treating chronic non-bacterial prostatitis (CNBP), and its effect on the inflammatory cytokines in prostatic fluid. Methods A hundred CNBP patients were randomized into a treatment group and a control group, 50 in each group. The control group was intervened by oral administration of Tamsulosin Hydrochloride sustained-release capsules, while the treatment group was additionally treated with acupuncture-moxibustion. After 28-day treatment, changes of IL-6, IL-8, IL-10, IFN-γ, COX-2, PGE2, TNF-α, MIP-2, and iNOS contents were observed, and the clinical efficacies were compared. Results The IL-6, IL-8, IL-10, IFN-γ, COX-2, PGE2, TNF-α, MIP-2, and iNOS contents were significantly changed after intervention in both groups (P<0.05). The contents of IL-6, IL-8, IFN-γ, COX-2, PGE2, TNF-α, MIP-2, and iNOS contents in the treatment group were significantly different from those in the control group after intervention (P<0.05). The total effective rate was 89.4% in the treatment group versus 78.3% in the control group, and the difference was statistically significant (P<0.05). Conclusions Acupuncture-moxibustion is an effective method in treating CNBP, and can improve the associated indexes of prostatic fluid.
5. Balloon expandable stent and self-expanding stent for patients with symptomatic basilar artery stenosis: An analysis of perioperative complications
Chinese Journal of Cerebrovascular Diseases 2012;9(1):16-20
Objective: To investigate the perioperative complications of balloon expandable stent and self-expanding stent (Wingspan stent) in the treatment of patients with symptomatic basilar artery stenosis. Methods: Sixty-two patients with symptomatic basilar artery stenosis admitted to the Department of Neurosurgery, the First Affiliated Hospital of Harbin Medical University from November 2006 to June 2011 were analyzed retrospectively. Twenty-four of them were treated with the balloon expandable stent and 38 were treated with the self-expanding stent. The residual stenosis rate and perioperative complications in patients of both groups were observed. Results: Circled digit oneEndovascular stenting was performed successfully in all the 62 patients. Among them, the stenotic rate from 83 ± 8% decreased to 10 ± 5% immediately after procedure in the balloon expandable stent group. The stenotic rate from 81 ± 11% decreased to 17 ± 10% immediately after procedure in the self-expanding stent group. Circled digit twoSeven (29.2%) of the 24 patients had perioperative complications in the balloon expandable stent group and 4 (10.5%) in the self-expanding stent group. The difference was not statistically significant (P = 0.061). However, if excluding the surgical factors, only comparing the stent-related ischemic complications, it showed that the incidence of complications (2/38, 5.3%) in the self-expanding stent group was significantly lower than that (7/24, 29.2%) in the balloon expandable stent group. The difference was statistically significant (P = 0.022). Observing from the pathological standpoint, it showed that the patients of Mori C type has higher incidence of complications. Conclusion: Compared to the balloon expandable stent, the self-expanding stent has a lower incidence of perioperative complications in the treatment of symptomatic basilar arterial stenosis, but the postoperative residual stenosis of the self-expanding stent is higher.

Objective To study the assisted diagnostic value and significance in precise surgery of MSCT angiography in torsion of ovar-ian tumors in children. Methods The dual-phase enhanced MSCT images data of 15 children patients with ovarian tumor torsion which were confirmed by surgery were retrospectively analyzed. Showed the vascular changes around the ovaries and judged the ovarian tumors arise and torsion side with the vascular reconstruction methods of multi-planar reconstruction (MPR),maximum intensity projection (MIP),volume rendering ( VR) ,then compared with the operation situation. Results Among the 15 cases aged from 2 months to 11 years old who were de-tected with MSCT scanning and angiography, there were 11 cases of benign tumor (9 cases of ovarian teratoma and 2 cases of serous cystade-noma) and 4 cases of malignant tumor (3 cases of yolk sac tumor and 1 case of malignant mixed germ cell tumor). MSCTA displayed that o-varian vessels changes were abnormal thickening and twisting of distal feeding artery and tumor vascular network formation;and there were thickening, tortuosity, increased density and a few visible‘whirl sign’ in draining veins. Preoperative MSCTA displayed ovarian tumor blood supply arteries were found 5 cases of downlink of ovarian artery and 10 cases of asscending branches of uterine artery. There were 4 cases of ovarian tumor originated from the left ovary combined with reverse and 11 cases originated from the right ovary combined with reverse, which were consistent with intraoperative findings. Intraoperative MSCTA provide information which helped accurate chose of the surgical incision, precise abruption of tumor blood vessels and resection of the tumor and ovarian lesions, thus saved the operation time and reduced the blood loss. Conclusion MSCT angiography can not only provide diagnosis information of torsion of ovarian tumors in children,but also more impor-tantly,it has an important assisted significance in precision surgery.

Objective To investigate the water infectivity in key water regions,and analyze the transmission risk of schisto-somiasis in suspicious and high-risk environments in Hubei Province in 2016. Methods Schistosome-endemic areas of the Yangtze River,the Hanbei River and the Fu River were chosen as the surveillance and forecast sites. The water infectivity was detected by using the sentinel mice during the flood season. The infection status of residents in the villages around the surveil-lance sites and the activities of human beings and domestic animals were surveyed. The emergency response system was initiated when the water infectivity areas were detected. Results From May to June,among the ten surveillance sites of the first batch, two positive spots with infected mice were found,accounting for 20%. All the recovered mice(totally 200)were dissected:five mice were infected,with a total infection rate of 2.5%. Totally five schistosome adult worms were collected,with mean worm bur-den of 1 worm per infected mouse. The site with cercariae-infected water body started the emergency response and no epidemic occurred. From August to September,among the eight surveillance sites of the second batch,the recovered mice(totally 160) were dissected,and no infected sentinel mice were found. Conclusion The sentinel mice method plays an important role in an-alyzing the schistosomiasis transmission risk in Hubei Province.
