Objective To investigate the effects of different doses of sufentanil on the minimum alveolar concentration (MAC) of sevoflurane for sedation in patients undergoing bronchoscopy. Methods ASA physical status I orⅡpatients of both genders, aged 20 ~ 65, undergoing bronchoscopy under general anesthesia,were randomly divided into 4 groups (n=20 each):control group (group C) and different doses of sufentanil groups (Sl, S2 and S3 groups). Sufentanil 0.1, 0.2 and 0.3 μg/kg in 5 mL of normal saline was intravenously infused before induction of anesthesia in groups of SI S2 and S3 respectively. While 5 mL of the normal saline was given instead in the group C The patients were mechanically ventilated after insert laryngeal mask. Anesthesia was maintained with inhalation of sevoflurane. Each time the concentration of sevoflurane at end expiration increased/decreased in the next patient depending on the concentration of sevoflurane at end expiration with which the former had no cough. The ratio between the two consecutive concentrations was 1.1. The middle point between the positive response and negative response served as a crossover pair. After at least 7 independent crossover pairs were observed in each group. The MAC and 95%confidence interval of sevoflurane were calculated. The time of anesthesia induction and analepsis was recorded. Results The MAC (95%CI) of sevoflurane was 3.0%(2.8%~3.3%), 2.3%(2.1%~2.5%), 1.9%(1.6% ~ 2.2%) and 1.6% (1.3% ~ 1.9%) in groups of C, S1, S2 and S3 respectively. The MAC of sevoflurane was significantly lower in groups of S1, S2, S3 than in the group C, and in groups S3 than in the group S1 (P<0.05). The time of anesthesia induction was significantly shorter in groups of S2, S3 than in the group C and significantly longer in groups S3 than in the group C. Conclusion Sufentanil of 0.1, 0.2, 0.3 μg/kg can significantly decrease the MAC of sevoflurane in patients undergoing bronchoscopy in a dose-dependent manner.

Objective To observe the effect of sling exercise therapy combined with acupuncture at Jiaji acupoints on balance function of stroke patients with hemiplegia. Methods From October, 2013 to October, 2015, 40 hemiplegic stroke patients with balance dysfunction were randomized to control group and treatment group equally. Both groups accepted routine rehabilitation, while the treatment group com-bined with sling exercise therapy and acupuncture at Jiaji acupoints. They were assessed with Berg Balance Scale (BBS), 10-metre maxi-mum walking speed (10MWS), Fugl-Meyer Assessment of lower limbs (FMA-L) and modified Barthel Index (MBI) before and four weeks after treatment. Results The scores of BBS, FMA-L and MBI, and 10MWS improved in both groups (t>2.249, P<0.05), and improved more in the treatment group than in the control group (t>2.954, P<0.01). Conclusion Sling exercise therapy combined with acupuncture at Jiaji acupoints can further improve the function of balance, walking and activities of daily living in stroke patients with hemiplegia.

Objective To explore different socio-demographic and clinical characteristics for early onset patients (EOP) with psoriasis and late onset patients (LOP) with psoriasis in Chinese population and to provide scientific evidences for establishing comprehensive prevention and treatment strategy for psoriasis.Methods Cross-sectional study was performed.A total of 942 diagnosed psoriasis patients who paid a visit to outpatient clinic in a tertiary hospital in China from 12th September 2013 to 19th May 2015 was consecutively enrolled and investigated.Exploratory analysis was conducted to detect the association between disease onset age and patients features.Results Among 942 enrolled psoriasis outpatients,the average age was (40.6 ± 13.6) years with a range from 5 to 80 years.The sex ratio was 2.1 in favor of male.The most observed type of psoriasis in the present study was psoriasis vulgaris (98.3％).The average psoriasis area and severity index (PASI) for patients were 9.47 ±7.63.Comorbidity was combined in 20.2％ cases.Patients with EOP had a significantly higher likelihood of family history of disease.Compared EOP to LOP,LOP had a significantly higher likelihood of comorbidities involvement (P ＜ 0.05) and significant higher BMI index (P ＜ 0.05).Conclusions The present study supports the hypothesis that there are clinical differences between EOP and LOP in Chinese population.Both dermatologists and patients should pay more attention to psoriasis-associated features,such as family history and comorbidity diseases involvements.

Objective To evaluate the effects of hydroxyapatite (HA) extensively-coated prosthesis on elderly patients undergoing hip arthroplasty.Methods From February 1997 to May 1999,96 patients Were treated with hydroxyapatite (HA) coated prosthesis and followed up for their hip arthroplasty.Their results were studied clinically and roentgengraphically to evaluate chiefly their Harris scores,complications and thigh pain.The survival of prosthesis was evaluated according to Kaplan-Meier methods.Results The 60 cases were followed up for eight years on average(range,sevon to nine years).Their mean Harris scores were improved from 42 preoperatively to 90 postoperatively.Fifty-eihgt cases felt no pain at their hip,but two did at their thigh.No radiolucent lines were observed.All the prostheses achieved bony stabilization and remolding.Conclusions HA coated prosthesis can achieve fine fixation,because it helps bone conduction,resists axial force and torsion,and reduces operative risks.

Objective To observe the effects of malt extract on prolactin expression and morphology of mammary tissue in hyperprolactinemia rats. Methods Metoclopramide hydrochloride was injected subcutaneously to establish hyperprolactinemia model. Sixty rats were divided into normal control group, model control group, bromocriptine group, high-dose, middle-dose and low-dose malt extract groups. Except normal control group, hyperprolactinemia model was established in the other groups. Bromocriptine (0. 389 mg·kg-1 ·d-1 ) was given to bromocriptine group. Malt extract (7. 98, 15. 96 and 31. 92 g·kg-1 ·d-1 ) was administered in low-dose, middle-dose and high-dose malt extract groups. Equal volume of purified water was given to normal control group and model control group. After 30 days of administration, PRL positive cell number of rat hypophysis was counted. RT-PCR was used to measure hypophysis PRL mRNA expression, and morphology of mammary tissues was observed by immunohistochemical method. Results PRL positive cell number was (2. 4±0. 3), (21. 7±0. 8), (3. 8± 0. 5), (4. 5±0. 4), (6. 7±0. 5) and (15. 8±1. 2) in normal control group, model control group, bromocriptine group, high-dose, middle-dose and low-dose malt extract groups. PRL mRNA expression level was (0. 31±0. 02), (1. 58±0. 06), (0. 45± 0. 04), (0. 49±0. 03), (0. 61±0. 04), and (0. 95±0. 09), respectively. As compared with normal control group, hypophysis PRL positive cell number and PRL mRNA expression level of high-dose and middle-dose malt extract group were increased significantly (P<0. 01), and hyperplasia of mammary glands appeared. As compared with model control group, hypophysis PRL positive cell number and PRL mRNA expression level of high-dose and middle-dose malt extract group was decreased significantly (P<0. 01), and hyperplasia of mammary glands was alleviated obviously. Conclusion Malt extract can effectively treat hyperprolactinemia and inhibit hyperplasia of mammary glands through significantly decreasing the expression of hypophysis prolactin in hyperprolactinemia rats.
