Objective This study was to evaluate breast fiberoptic ductoscopy (FDS) in the diagnosis and treatment of abnormal niple discharge(AND). [WT5”HZ]Methods [WT5”BZ] FVS 3500 superfine fiberscopy system was used to treat and diagnose 200 cases with AND. [WT5”HZ]Results [WT5”BZ] 210 orifices of nipple discharge were found in this group. FDS was successfully inserted into 204 orifices(97 0%).Early breast cancer was found in 9 cases(4 5%), papilloma and papillomatosis in 66 cases(33 0%),ductal ectasia and/or chronic inflammation in 96 cases(48 0%); “normal duct” in 29 cases(14 5%). Duct endoscopic biopsy was carried out in 10 cases. Chronic inflammation was cured by perfusion in 25 cases. 67 cases underwent surgery, diagnosis was confirmed by pathology in 95 0% with a positive rate 3 times as high as that of smear cytology.Conclusions FDS enables the evaluation on 4th ductal lumen and detection of early breast cancer. Interventional treatment was successful in some intraductal papilloma and chronic inflammatory disease.

Objective:To compare the clinical efficacy and safety of nalmefene hydrochloride injections and Naofukang injections in the treatment of the patients with severe head injury. Methods:Totally 60 cases of patients with severe head injury were randomly divided into the observation group and the control group. The two groups were all given the conventional therapy, such as dehydration, expansion and anti-infective therapy. On the basis of the conventional therapy, the observation group was treated with nalmefene hydro-chloride injections, 0. 4-0. 6 mg in 0. 9% sodium chloride injections, ivd, qd, while the control group was given Naofukang injections, 4-9 g in 5% or 10% glucose injections, ivd, qd. The treatment course was 2 weeks. After the 3-day treatment, the heart rhythm, the incidence of respiratory abnormalities and intracranial pressure were compared between the two groups. After the 10-day treatment, the total efficacy and complications in the two groups were also recorded and compared. Results:After the 3-day treatment, the incidence of abnormal heart rhythm and respiratory abnormalities in the observation group were significantly lower than that in the control group (P<0. 05), the intracranial pressure in the observation group was better than that in the control group (P<0. 05). After the 10-day treatment, the total effective rate of the observation group was 93. 3%, which was much higher than that in the control group ( P<0. 05). After the treatment, the incidence of respiratory infections, acid-base unbalance and upper gastrointestinal bleeding in the ob-servation group was significantly lower than that in the control group (P <0.05). Conclusion: The clinical efficacy of nalmefene hydrochloride injections in the treatment of patients with severe traumatic brain injury is significant with promising safety, which is bet-ter than that of Naofukang injections.

Objective To study the optimum conditions for extracting total flavonoids from Acanthus illicifolius through the two extraction processes.Methods An orthogonal test of L_9 (3~4)was designed to select optimum operation conditions for extracting total flavonoids from Acanthus illicifolius through Soxhelt and ultrasonic extraction process.According to the output of total flavonoids under the different extraction conditions,which were selected as ethanol contents,extraction temperatures and extraction time for Soxhelt extraction process, and extraction time,ethanol contents and ratio of liquid to material for ultrasonic extraction process.Results The optimum conditions were established as follows:ethanol content 60%, extraction temperature 85℃and extraction time 2.5h in Soxhlet extraction process;Ethanol content 50%,extraction time 50min,ratio of liquid to material 40:1 in ultrasonic extraction process.The extraction temperature was the main factor on the Soxhlet extraction process, and the ethanol content on the ultrasonic extraction process.Conclusion The technology of ultrasonic extraction is better than that of Soxhlet extraction to extract the total flavonoids from Acanthus illicifolius.The max output of total flavonoid from Acanthus illicifolius can reach to 3.82%.

Objective To investigate the effect of antimicrobial-impregnated incise drape on preventing surgical site in-fection(SSI)following neurosurgical operation.Methods Patients undergoing neurosurgical operation from January to De-cember 2012 were divided into two groups:antimicrobial-impregnated incise drape group(group A)and general incise drape group(group B).The occurrence of SSI and risk factors for SSI were analyzed.Results Percentage of drape lifting at the wound edge in group A was lower than group B(38.3%[98/256]vs 96.88% [248/256],χ2 =200.57,P <0.01).Among 512 patients,SSI rate was 3.32%(n=17),SSI rate in group A was lower than group B(1.56%[4/256]vs 5.08%[13/256],χ2 = 7.93,P <0.05 ).Multivariate analysis revealed that body mass index ≥24,perioperative hypothermia,smok-ing,perioperative length of hospital stay ≥5 days,and lack of drape use were independent risk factors for SSI following neurosurgical operation.Conclusion Whether antimicrobial-impregnated incise drape is used in neurosurgical operation is one of the independent risk factors for SSI following neurosurgical operation,it can effectively reduce the drape lifting rate and incidence of SSI,and is recommended to be used in neurosurgical operation.

This experiment was designed to explore the correlation between the mechanism of immobilization-induced skeletal muscle atrophy and the apoptosis of muscular cells. The models of skeletal muscle atrophy induced by immobilization for different length of time were established according to Sievanen II methods. 24 rabbits, each of them having one hind leg fixed by the tubal plaster and the other one free as control, were randomly divided into four groups depending on time of fixation (3, 7, 14, and 28 days respectively). The animals were sacrificed by the end of fixation. TdT-mediated d-UTP nick end labeling (TUNEL) was used to investigate the apoptotic muscle cells in the animal's bone. By comparing the apoptotic muscle cells with the morphology of the skeletal muscle, the correlation between cell apoptosis and skeletal muscle atrophy were analyzed. Apoptotic muscle cells did appear after immobilization in the atrophied skeletal muscle. In various groups, some cells with false positive stained TUNEL were found in the atrophic muscle, which could be distinguished from apoptotic cells by their characteristics. In conclusion, cell apoptosis participates in the process of skeletal muscle atrophy induced by immobilization; the amount of apoptotic cells is strongly associated with the time of immobilization, its peak appears on the 14th day of immobilization; the distribution of apoptotic skeletal muscle cell varies with the time of fixation. The severity of skeletal muscle atrophy is associated with the degree of the muscle cell apoptosis.

Objective: To investigate the effects of retinoid-related orphan receptor γ (RORγ) gene on proliferation and metastasis of human colon cancer cells． Methods: RORγ knockdown cell lines were constructed and the knockdown efficiency was detected by RT-qPCR and Western blot assays ; MTT，colony formation，Transwell and wound healing assays were used to detect cell proliferation and metastasis ; the expression of epithelial-mesenchymal transition (EMT) related proteins was detected by Western blot．The relationship between RORγ gene expression and immune cell infiltration in tumor microenvironment was analyzed using TIMER 2. 0 database. Results : The knockdown of RORγ enhanced the viability (F = 157. 40，P＜0. 01) ，clonogenesis (F = 61. 35，P＜0. 01) ，migration (F = 13. 00，P＜0. 01) ，invasion (F = 21. 26，P＜0. 01) and wound healing ability (F = 877. 2，P＜0. 01) of colon cancer cells，inhibited the expression of E-Cadherin，and promoted the expression of vimentin and N-Cadherin．TIMER 2. 0 database analysis showed that RORγ expression in colon adenocarcinoma ( COAD) tissues was associated with multiple immune cell infiltrates． Conclusion Downregulation of RORγ expression promoted the proliferation and metastasis of colon cancer cells.
