ObjectiveTo evaluate the efficacy and safety of combination therapy of tamsulosin and solifenacin for benign prostatic hyperplasia ( BPH ) with overactive bladder ( OAB ).Methods82 patients with OAB and coexisting BPH were randomly divided into tamsulosin group ( n = 38 ) and combination group ( n = 44). The ages were from 50 to 75 y ( averaged, 56.8 ± 8.6). Inclusion criteria: the mean frequency of micturition ≥8 times per day, the frequency of nocturia ≥2 times per day, voiding volume ＜200 ml each time; for the overactive bladder symptom score ( OA BSS), the 3 rd score ＞ 2, total score ＞ 3. The tamsulosin group accepted tamsulosin 0.2 mg once daily, the combination group accepted tansulouxin 0.2 mg and solifenacin 0.2 mg once daily. Both groups were maintained the corresponding therapy for 12 weeks.The international prostate symptom score (IPSS), Qmax, residual urine volume, OAB score and adverse reactions were recorded.ResultsThe values of IPSS ( 19.5 ±2.2 vs 15.6 ±2.4, P =0.027), the voiding symptom score ( 15.6 ± 2.4 vs 3.4 ± 1. 7, P = 0. 022) and Qmax ( 13.7 ± 3.8 vs 16.6 ± 4.1, P = 0. 034 )improved significantly after treatment in tamsulosin group ( P ＜ 0. 05 ). The values of IPSS ( 19.7 ± 2.3 vs 9.7 ± 3.0, P ＜0. 001), the storage symptom score (13.8 ± 1.9 vs 5.6 ± 1.6, P ＜0. 001 ), OABSS (10.3 ±1.8 vs 5.3 ±1.3, P ＜0.001) and Qmax(14.1 ±4.1 vs 17.2 ±3.5, P=0.027) also improved significantly after treatment in combination group ( P ＜ 0. 05 ). The values of IPSS ( 9.7 ± 3.0 vs 15.6 ±2.4, P ＜ 0.001 ), the storage symptom score (5.6 ± 1.6 vs 12.0 ± 1.6, P ＜ 0.001 ) and OABSS ( 5.3 ±1.3 vs 9.7 ± 2.7, P ＜ 0. 001 ) improved significantly in combination group than those in tamsulosin group ( P ＜0.001 ). There were no difference between two groups in values of the voiding symptom score, Qmax and residual urine volume ( P ＞ 0.05 ). The incidences of adverse reactions in tamsulosin group and combination group were 7.9％ (3/38) and 20.5％ (9/44) without significant difference. There was no acute urinary retention in both groups.ConclusionsIt is effective and safe for patients with BPH and OAB to accept combination therapy of tamsulosin and solifenacin.

The oligometastasic stage is an intermediate state with mild biological invasion,in which spread may be limited to specific organs and polymetastases do not occour.The number of metastatic tumors is limited less than five.Local therapy such as radiotherapy,surgery and radiofrequency ablation for the relapsed sites could thus improve patients survival.The expression of miR-200 family characterizes oligometastasis(es).Correct understanding and familiarization with treatment of oligometastasis may change the traditional therapeutic strategy of advanced tumors,and some advanced cancer patients may achieve curable results.

Objective To investigate the status of self-care ability and cognition among disabled elderly,and to analyze the relationship between self-care ability and cognition,then analyze their influencing factors.Methods A total of 813 disabled elderly accepted long-term care at community or facility were recruited by stratified sampling method and investigated by socio-demographic questionnaire,activities of daily living and short portable mental status questionnaire.Results The total scores of self-care ability of the long-term care disabled was 32.01±11.59,and the total points of cognition was 3.77±3.24.Disabled elderly with severe disorders of self-care ability had a higher obstacle rate in every cognition ability than those with mild disabilities (P＜0.001).There were differences in orientation and memory function with different persistent disabled time (x2 =11.875,14.758,P＜0.01).Disabled elderly with cognition obstacles have a higher obstacle rate in every self-care aspect than those with normal cognition (P＜0.01).The multiple regression analysis showed that the educational level (β=-0.067),arital status (β=-0.071),disabled persistence time (β=0.121),orientation ability (β=0.403),the amount of cognition obstacles (β=0.443) were the influence factors of Basic Activities of Daily Living(BADL) among disabled elderly ; and disabled persistence time (β=0.116),orientation ability (β=0.417),recalled ability (β=0.275),memorial ability (β=0.189),calculative ability (β=0.257),the amount of cognition obstacles (β=0.358) were the important factors influence Instrumental Activities of Daily Living(IADL).Conclusion The self-care ability and cognition of the long-term care elderly were declining sharply,and influencing each other.It is advisable to offer them direct long-term care service combined with the laws and characteristics of cognition and self-care ability.

Objective To analyze the frail status and influencing factors of inpatients in geriatrics department.Methods A total of 170 patients aged ≥ 65 years in Geriatrics Department in our hospital were selected.Frailty was defined according to the Clinical Frailty Scale (CFS),and patients were divided into non-frail group and frail group.The differences in comorbidity,physical function,nutrition,cognitive,psychological,geriatrics syndromes,medication,social support and other aspects were analyzed between the two groups by using Comprehensive Geriatrics Assessment(CGA),and correlationof the factors with frailty was evaluated.Results There were 83 (49.0％)patients in frail group and 87 (51.0％)in non-frail group.In frail group versus non-frail group,Charlson comorbidity index was(2.7±2.0)vs.(1.9±1.1),and cumulative illness rating scale was(10.8±3.7) vs.(8.0±2.6) (all P＜0.05);mini-nutrition assessment was(11.2±2.3)vs.(13.0±1.3),and simple cognitive score was(2.7±1.3)vs.(4.1±0.9)(all P＜0.05).Grip,five chair rising,timed get-up and go test,walking speed,SPPB showed statistically significant differences (all P＜ 0.05) between frail group and non-frail group:(20.7±6.6)kg vs.(27.96.7)kg,(30.4±17.5)vs.(12.9±4.1),(23.7± 9.9)vs.(11.7± 3.3),(0.5 ± 0.2)m/s vs.(0.9± 0.2)m/s,(5.6 ± 2.3) vs.(10.3±1.8)respectively.The incidences of incontinence,visual impairment,hearing impairment,sleeping disorder,oral problems,chronic pain,anxiety or depression and fall history were higher in frail patients than in non-frail patients.Living alone,the widowed,nursing staff employment proportion were higher in frail group than in non-frail group.Level of education was lower in frail group than non-frail group.Logistic regression analysis showed that BMI,the walking speed and the number of geriatrics syndromes had a significant impact on frailty(OR=0.789,0.000,2.745,all P＜0.05).Conclusions Incidence rate of frailty in elderly hospitalized patients is high.To identify frailty of hospitalized patients,comprehensive geriatric assessment can be used for understanding frail characteristics and its influencing factors for hospitalized old patients,so as to provide evidence for the reasonable treatment programs.

Objective To investigate the epidemiology of spinal cord injuries (SCI) in hospital. Methods 423 patients with SCI were reviewed. esults The ratio of male to female was 15.3∶ 1, aged (40±11) years. The coal mine-related staff was the most (61.7%), mainly aused from coal blocks dropping (53.26%). 135 cases (31.91%) injured in cervical vertebra, and 187 cases (44.21%) in lumbar. There were 92 (45.39%) cases were complete injury. The most frequent complication of SCI were urinary tract infection, pressure sore and pulmonary nfection. The factors correlated with the complication were the degree of ASIA Impairment Scale, the period of admitted to hospital after injury, nd the surgery (P<0.05). The expenditure of hospitalization was mainly provided by oneself (73%). Conclusion It is important to improve he occupation prevention, enlarge the coverage of medical insurance, and promote pre-hospital care to prevent SCI.

Objective: To observe the effect of different moxibustion durations on rats with rheumatoid arthritis (RA) and to evaluate the relationship between moxibustion amount and moxibustion efficacy.Methods: Eight rats were randomly selected as a normal group from the 40 male Sprague-Dawley (SD) rats, and the other 32 rats were used to establish typeⅡ collagen-induced RA models. After successful modeling, the 32 rats were randomly divided into a model group, a moxibustion for 20 min group, a moxibustion for 40 min group and a moxibustion for 60 min group, with 8 rats in each group. Rats in the normal group did not receive modeling and moxibustion intervention; rats in the model group did not receive moxibustion after modeling; rats in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group were treated with moxibustion at Shenshu (BL 23) and Zusanli (ST 36) for 20 min, 40 min and 60 min, respectively. Six days were a course of treatment, with a total of 3-course treatments and a 1-day rest between the courses of treatment. After treatment, the serum levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, arthritis index (AI) scores, toe volumes and pathological score of synovitis were evaluated in the rats.Results: Compared with the normal group, the serum IL-1β and TNF-α levels, and the toe volumes in the model group were increased, and the differences were statistically significant (P<0.01), before the treatment. Compared with the model group, the serum IL-1β and TNF-α levels, toe volumes and arthritis index (AI) scores were significantly decreased in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group (P<0.05 orP<0.01 ). Compared with the moxibustion for 20 min group and the moxibustion for 60 min group, serum IL-1β and TNF-α levels, toe volumes and AI scores were decreased more significantly in moxibustion for 40 min group, and the differences were statistically significant (P<0.05 orP<0.01). There were no significant differences in serum IL-1β and TNF-α levels, AI scores and toe volumes between the moxibustion for 20 min group and the moxibustion for 60 min group (allP>0.05). The synovial histopathological improvement was the most obvious in the moxibustion for 40 min group, when the synovial histopathological changes were compared among the moxibustion for 20 min group, moxibustion for 40 min group and moxibustion for 60 min group.Conclusion: The therapeutic efficacy of moxibustion for 40 min in RA rats was more significant than that of moxibustion for 20 min and moxibustion for 60 min, indicating that the duration of moxibustion is the main factor affecting its therapeutic efficacy.

OBJECTIVETo investigate the effects of different concentrations of lipopolysaccharide (LPS), tumor necrosis factor α (TNFα), interleukin-6 (IL-6), dexamethasone (Dex), and insulin on the mRNA and protein expressions of GPR54 in the MCF7 cell line in vitro.

METHODSMCF7 breasr cancer cells were cultured and treated with different concentrations of LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L). Those treated with culture fluid only served as controls. The mRNA and protein expressions of GPR54 were measured by real-time PCR and Western blot, respectively, after 6, 24, 48, and 72 hours of treatment.

RESULTSCompared with the blank con- trol, LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L) significantly increased the expressions of GPR54 mRNA (P < 0.05) and protein (P < 0.05).

CONCLUSIONLPS, TNFα, IL-6, Dex, and insulin evidently increase the expression of GPR54 in the MCF7 cell line, indicating their influence on the function of gonads by regulating the GPR54 level.
