Objective To investigate the effect of early warning face pattern of weight combined with health education in weight management of maintenance hemodialysis patients.Methods Toally 223 maintenance hemodialysis patients hospitalized in the hospital from July to December 2014 (17,617 cases of hemodialysis) were set as the control group and 223 maintenance hemodialysis patients from January to June 2015 (17,281 cases of hemodialysis) were set as the experiment group.The control group was given routine health education and the experiment group was given health education and early warning face pattern of weight.The two groups were compared in terms of the ratio between interdialytic weight gain (IDWG) and interdialytic dry weight ratio (IWGR) as well as the hemodialysis-related complications.Results The IDWG/IWGR ratio in the experiment group was significantly better than that of the control group (P＜0.05).The incidence of hemodialysis-related complications were significantly lower than that of control group.Conclusion Early warning face pattern of weight used in health education can effectively control the patient's interdialytic weight gain (IDWG) and reduce the hemodialysis-related complications.

Objective To investigate the protective effects of midazolam on noise-induced hearing loss in guinea pigs by testing reactive oxygen species (ROS) level in the cochlea and plasma SOD and MDA. Methods Totally forty male pigmented guinea pigs were randomly divided into four groups: control (C) , midazolam (M), normal saline (S) and noise-induced deafened (D) groups, with ten guinea pigs in each. Groups M, S and D were exposed to a continuous noise (4kHz , octave band, 100dB SPL) 3h every day for 3 consecutive days. Group M was treated with midazolam, which was administered intramuscularly (0.1mg/kg) 24h before noise exposure, and immediately upon and during noise exposure. Group S was exposed to noise and treated with the same volume of normal saline intramuscularly, the time of injection was the same as that of Group M. Group C was not exposed to noise, but was treated with midazolam intramuscularly, the time of injection and the dosage were the same as those of Group M. Group S was exposed to noise and treated with normal saline intramuscularly ,the time of injection was same with that of Group M.Group D was exposed to noise only. All animals received auditory brainstem response (ABR) threshold recording before and immediately after noise exposure. Blood was collected when the guinea pigs were killed after the last ABR threshold recording, and serum SOD activity and MDA content were detected. Both the cochleae were removed and prepared for ROS assay. Results After noise exposure, ABR threshold shift (1.6±1.5) and ROS content [(291.10±2.30)u/mL] in Group M were significantly lower than those in Groups S and D [41.7±3.3, 44.3±3.9; (348.52±3.60)u/mL, (315.56±6.70)u/mL, P<0.05]. Serum SOD activity and MDA content were significantly increased in Group M, but the amplitude was less than that in Groups S and D.Conclusion Midazolam can prevent noise-induced hearing loss by reducing the increased ROS level in the cochlea after noise exposure.

AIM To investigate actions of total paeony glycoside(TPG) on learning and memory capacity and related products of metabolism of senile mice induced by D galactose. METHODS The subacute senile mouse models induced by injection of D galactose subcutaneously were used. RESULTS TPG could improve the learning and memory capacity of model mice in shuttle test and enhance spatial resolution in water maze test. TPG not only reduced the content of monoamine oxidase(MAO) and inhibited the decrease of cholinesterase(CHE) significantly, but also lessened the level of malondialdehyde(MDA) and inhibited the decrease of superoxide dismutase(SOD) in cerebrum of model mice. TPG still promoted the recovery of lobar atrophy and hypoimmunity of senile mice remarkedly. CONCLUSION TPG possesses obvious effects of improvement on learning, spatial resolution and delaying senility.

Objective The objective of this study was to investigate the clinicopathological features and rational treatment of primary fallopian tube cancer(PFTC).Methods The clinical and pathological data of 39 patients with primary fallopian tube cancer from January 2006 to July 2016 in Beijing Tongren Hospital of Capital University were retrospectively analyzed.Results There were 39 cases of undifferentiated carcinoma,including 1 case of undifferentiated and transitional cell carcinoma,37 cases of undifferentiated adenocarcinoma,or 29 cases of simple adenocarcinoma and 10 cases of mixed type.Among them,7 cases were treated with clear cell carcinoma,endometriosis in 2 cases,combined with transitional cell carcinoma in 1 case.Extra-pelvic metastases were the most common site of the omentum with 17 cases.The preoperative test CA125 was increased in 13 cases and 38 patients received postoperative chemotherapy.The 5-year overall survival rate of 39 patients was 51.3%.Univariate analysis showed that postoperative pathologic stage(Ⅰ~Ⅱ vs.Ⅲ,P<0.001),intraoperative residual lesion size(P<0.001),omentum metastasis(P<0.001),ovarian metastasis(P=0.034),retroperitoneal lymph node metastasis(P=0.018)and preoperative CA125 elevation(P=0.002)were associated with prognosis,while age(P=0.310)and pathological grade(P=0.663)were not associated with prognosis.Multivariate analysis showed that the number of patients with postoperative lymph node metastasis(P=0.018)and preoperative CA125 elevation(P=0.002)were correlated with prognosis(HR=1.202,95% CI:2.354~63.290,P=0.003) and pathological stage(HR=3.810,95% CI:1.202~12.079,P=0.023).They were associated with prognosis as independent prognostic factors.Conclusion Tumor pathologic staging and omentum metastasis are important prognostic factors influencing the prognosis of patients with primary fallopian tube cancer.Early diagnosis and complete operation can improve the prognosis of patients.

Objective To investigate the clinical features of primary retroperitoneal fibrosis (RPF), and to find out better method for diagnosis and therapy. Methods Nine patients with primary RPF in Peking Union Medical College Hospital since 1990 to 2003 were analyzed retrospectively. Results All patients had abnormal findings in CT or MRI, and 8 of them had chronic non-specific inflammation of the retroperitoneum in pathology. Six patients had renal involvement and 2 of them had severe renal failure. Eight of the patients had received therapy with corticosteroid or tamoxifene. Conclusions RPF is an uncommon collagen vascular disease characterized by a chronic non-specific inflammation of the retroperitoneum.Because of the atypical manifestations of RPF, awareness of the disease is important.CT and (or) open biopsy remains the gold standard for diagnosis.Management typically includes surgery and drug treatment.Corticosteroid therapy or more recently,tamoxifen has been used successfully. The clinical and radiographic improvement with drug treatment has been seen in several patients and confirmed the diagnosis,thereby early diagnosis and treatment can bring the patient more excellent renal and general outcome.
