OBJECTIVETo observe the curative effect of Qianjin Kouchuang Jiawei Granule (QKJG) on recurrent oral ulceration [yin deficiency fire excess type (YDFET)].

METHODSTotally 120 patients who suffered from recurrent oral ulceration (YDFET) were randomly assigned to two groups, the experiment group and the control group, 60 in each group. Patients in the experiment group took QKJG, 20 g each time, twice per day, while those in the control group took Kouyanqing Granule (KG) , 20 g each time, twice per day. Fourteen days consisted of one therapeutic course, two for all. Scores for patients' symptoms and signs (ulcer area, exudation, hyperaemia, edema, the number of ulceration, burning sensation, and pain degrees) were assessed before treatment, at day 3 and 7 after treatment. Short-term efficacy was assessed by visual analogue scale (VAS). The total paralysis time and the total number of ulceration at month 12 after treatment were taken as judgment for long-term efficacy. Results Compared with before treatment in the same group, symptoms and signs were obviously improved at day 3 and 7 after treatment in the two groups (P < 0.05). Compared with the control group at day 3 after treatment, the improvement of edema, exudation, pain degree, and burning sensation was more obvious in the experiment group (P < 0.05, P < 0.01). The improvement of edema, pain degree, and burning sensation at day 7 after treatment was more obvious in the experiment group than in the control group (P < 0.05). As for short-term efficacy, the total effective rate was 86.67% (52/60 cases) in the experiment group and 83.33% (50/60 cases) in the control group, with no statistical difference between the two groups (P > 0.05). As for long-term efficacy, the total effective rate was 90.00% (54/60 cases) in the experiment group, significantly higher than that of the control group with statistical difference [81.67% (49/60 cases), P < 0.05]. At month 12 after treatment, the total number of ulceration was reduced and the paralysis time of ulcer attack prolonged in the experiment group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONQKJG showed better long-term efficacy than that of KG in treating recurrent oral ulceration (YDFET).

Objective: To investigate the risk factors of sarcopenia among the elderly, so as to provide insights into prevention of sarcopenia among the elderly. Methods: A case-control study was conducted. A total of 371 patients with sarcopenia at ages of 60 years and older admitted to the First Affiliated Hospital of Xinjiang Medical University were selected as the case group, while 1∶1 matching healthy volunteers by gender, age and ethnicity in the hospital during the study period served as controls. Participants' demographics, disease history and nutrition were collected using questionnaire surveys, and factors affecting the development of sarcopenia were identified using a multivariable conditional logistic regression model. Results: Participants in the case group included 171 men (46.09%), 254 Han ethnic populations (68.46%) and had a mean age of (73.04±7.83) years. Univariable conditional logistic regression analysis showed that participants with smoking, alcohol consumption, hypertension, diabetes, dyslipidemia, thyroid dysfunction and malnutrition had higher risk of developing sarcopenia (all P<0.05). Multivariable conditional logistic regression analysis identified hypertension (OR=1.851, 95%CI: 1.344-2.549), diabetes (OR=1.537, 95%CI: 1.068-2.213), dyslipidemia (OR=1.542, 95%CI: 1.112-2.140) and thyroid dysfunction (OR=2.575, 95%CI: 1.838-3.609) as risk factors of sarcopenia among the elderly. Conclusion Hypertension, diabetes, dyslipidemia and thyroid dysfunction may be risk factors of sarcopenia among the elderly.

Objective To explore the efficacy of calmodulin antagonist berbamine(BBM)on multidrug resistance(MDR)reversal and its mechanism. Methods Human breast cancer cell line MCF7 and its adriamycin-resistant counterpart MCF7/ADR were used in the study.The cells were cultured with ADR and different concentration of BBM. MTT assay was used to analyze the effect of BBM on cell growth inhibition.According to the MTT assay,the 50% inhibitory concentration(IC 50 ),the multiples of drug resistance and increased sensitivity of ADR were calculated.The concentration of intracellular ADR and expression level of P-glycoprotein(P-gp)were detected by flowcytometry(FCM).The mRNA expression level of mdr1 gene was detected by semi-quantitative reverse transcriptase polymerase chain reaction(RT-PCR)with ?-actin as internal reference. Results The IC 50 of ADR in MCF7 and MCF7/ADR cells were(0.98?0.06)?mol/L and(101.20?5.72)?mol/L,respectively.The resistant multiple of MCF/ADR cells to ADR was 103 folds higher than that of MCF7 cells.BBM increased the chemo-sensitivity of ADR in MCF7/ADR cells with dose-dependent relationship,i.e.when 5*!?mol/L ,10*!?mol/L and 20*!?mol/L BBM was added into the culture the chemo-sensitivity of ADR was increased to 2.76,5.88,and 28.26 folds(P

Background p21 is a cyclin-dependent kinase inhibitor,and it can prevent cells from going through the G1/S phase checkpoint and inhibit cell proliferation.Stuies determined that the expression level of p21 WAF1/CIP1 is associated with proliferative diseases.Traumatic proliferative vitreoretinopathy (PVR) is a proliferative response of eye.Understaining the relationship of dynamic expression levels of p21 WAF1/CIP1 in PVR is of significance for the prevention and management of PVR.Objective This study was to investigate the expression of p21 WAF1/CIP1 during the course of experimental traumatic PVR in rabbits.Methods Fifty-four pigmented rabbits were randomized into the normal control group and different experimerital groups,and one lateral eye of each rabbit served as experimental eye.PVR models were established by intravitreal injection of human platelet-rich plasma (PRP) (0.4 ml)combined with cryotherapy for 5 seconds,and vitreous and retinas were examined with B type sonography.The rabbits were sacrificed in 7,14,21 and 28 days after operation,and histopathological examination of the retinas was performed by haematoxylin and eosin stain.The expression levels of p21WAF1/CIP1 protein and gene were detected by immunohistochemistry,Western blot and reverse transcription-PCR (RT-PCR).The use and care of the rabbits complied with Statement of ARVO.Results B type sonography showed that the retinal morphology was normal in the normal control group.However,the proliferative membrane was gradually thickened 1 to 7 days after operation.Retinal folds of rabbits were seen in 7 days,and tractional retinal detachment was found in 14 days and 28 days after operation.The histopathological examination of the retinas showed epiretinal membrane and infiltration of inflammatory cells 7 days and fixed ruffle 28 days after operation.The p21WAF1/CIP1 was strongly expressed in the cell nucleus of retinal ganglion cell layer (GCL) and inner nuclear layer (INL) in the normal control group,and the expression was gradually weakened after modeling,with the weakest expression in the retinas in 14 days after modeling.The relative expression levels of p21 WAF1/CIP1 protein was 0.74±0.08,0.60±0.05,0.56±0.03,0.74±0.02 and 0.65 ±0.04 in the normal control group,postoperative 7-day group,postoperative 14-day group,postoperative 21-day group and postoperative 28-day group,respectively,showing a significant difference among the groups (F =20.55,P =0.00),and the expression levels of p21WAF1/CIP1 protein were significantly lower in the postoperative 7-day group and postoperative 14-day group than those of the normal control group,postoperative 21-day group and postoperative 28-day group (all at P＜0.05).The relative expression levels of p21 WAF1/CIP1 mRNA was 0.65 ± 0.09,0.57 ± 0.05,0.45 ±0.04,0.46±0.02 and 0.47±0.04 in the normal control group,postoperative 7-day group,postoperative 14-day group,postoperative 21-day group and postoperative 28-day group,respectively,with a significant difference among the groups (F =18.06,P =0.00),and the expression levels were significantly lower in the postoperative 14-day group,postoperative 21-day group and postoperative 28-day group than those of the normal control group and postoperative 7-day group (all at P＜0.05).Conclusions The dynamic expression of p21WAF1/CIP1 in the retinas is consistant with the prograssion of traumatic PVR,and the reduce tendency of p21 WAF1/CIP1expression is similar to cell prolieration change,indicating that reduce of p21WAF1/CIP1 expression in the retinas may promote the development of traumatic PVR.

[ABSTRACT]OBJECTIVETo explore the clinical characteristics of benign paroxysmal positionalvertigo(BPPV) after sudden hearing loss and to observe the curative effect. METHODS36 patients with BPPV after sudden hearing loss were observed.And their therapeutic findings were compared with that of the 50 patients with primary BPPV and 40 patients of sudden hearing loss without vertigo. RESULTSBPPV after sudden hearing loss occurred in the hearing loss ears, of which 27 cases were posterior semicircular canal lithiasis and 3 cases were horizontal semicircular canal lithiasis. The 36 patients with BPPV after sudden hearing loss and 40 patients with primary BPPV were cured after several times of reposition maneuver treatment.The efficiency of 40 patients of sudden hearing loss without vertigo was higher than that of 36 patients with BPPV after sudden hearing loss.CONCLUSIONBPPV after the sudden hearing loss mainly occurs in the posterior semicircular canal. The therapeutic efficacy of canalith repositioning maneuver for the secondary BPPV was similar to that of the primary BPPV.The therapeutic efficacy of sudden hearing loss without vertigo was superior to sudden hearing loss with BPPV.

Objective To investigate the value of otolith-repositioning maneuver combined with medical treatment on benign paroxysmal positional vertigo in the elderly patients.Methods 176 elderly people who suffered from benign paroxysmal positional vertigo were randomly divided into observation group and control group (n=88,each).All patients were treated with basal medicine treatment and compulsive position for 21 days,and patients in the observation group were treated with otolith repositioning maneuver added on the basis.The clinical efficacy and adverse reactions were observed and compared between the two groups after treatment.Results The curative rate and effective rate were higher in observation group than in control group at 2,3 weeks after treatment [50.0％ (44/88) vs.11.4％ (10/88),70.5％ (62/88) vs.47.7％ (42/88),77.3％ (68/88) vs.29.5％ (26/88),93.2％ (82/88) vs.86.4％ (76/88),x2 =37.32,73.32,37.32,53.43,respectively,all P＜0.05].Dizziness combined with nausea and vomiting,and walking instability were both found in the two groups,which had no statistical difference (x2 =3.25,P＞0.05).Patients in observation group developed arrhythmia and Tumarkin otolith crisis after treatment.The transfer rate of surgery was lower in observation group than in control group (x2 =45.43,P＜0.01).Conclusions Otolith-repositioning maneuver combined with medical treatment have good clinical effect and safety on benign paroxysmal positional vertigo in the elderly.

Objective To explore the roles of reactive oxygen species(ROS) and TGF-?1 in aldosterone-induced PAI-1 production.Methods Quiescent rat mesangial cells (MCs) were treated by aldosterone.The level of ROS in MCs induced by aldosterone was measured by confecal laser scanning microscopy and the TGF-?1 activity in the supematant of culture was measured by mink lung epithelial cell (Mvllu) proliferation inhibition MTT assay.Then,before the addition of aldosterone,MCs were pretreated with NAC or TGF-?1 neutralizing antibody to decrease cellular ROS or inhibit activity of TGF-?1 induced by aldosterone respectively.PAI-1 mRNA was examined by semi-quantification RT-PCR and PAI-1 protein by Western blotting.Results The intracellular ROS induced by aldosterone increased by 5-fold compared to that of control group,and the activity of TGF-?1 stimulated by aldosterone increased markedly.TGF-?1 neutralizing antibody and NAC effectively decreased aldosterone-induced PAI-1 mRNA expression by 30% and 32%,and PAI-1 protein expression by 21% and 11%,respectively.However,neither TGF-?1 neutralizing antibody nor NAC alone could regulate aldosterone-induced PAI-1 mRNA and protein expression to normal level in 24 hours.Conclusions ROS and TGF-?1 play important roles in up-regulation of aldosterone- induced PAI-1 in MCs.ROS and TGF-?1 are not the exclusive pathway of PAI-1 expression induced by aldosterone in MCs.

Objective To study the clinical characteristics and outcome of cytomegalovirus(CMV) infection in infants.Methods All data including time of infection,clinical characteristics,laboratory tests and outcome of CMV infections in hospitalized infants were collec-(ted) and analyzed from January,1994 to July,2004.Results In 87 infected infants,congenitally infected newborns,perinatal infection in infants and postnatal infection in infants accounted for 27.6%,62.0%,16.6%,respectively.CMV hepatitis was the most frequent type of disease with the incidence of 41.3%,in which the incidence of splenomegaly was 10.3%.Most of CMV hepatitis infants had a good prognosis with the improved rate 80.5%.Central nervous system abnormality(including abnormal intension of muscle,convulsion,ocular and hearing abnormalities) occurred only in congenital and perinatal infection with the incidence of 20.4%.Generalized infection,the incidence of congenital infection and perinatal infection was 16.7%,1.8%,respectively.It did not occur in postnatal infection.The mortality rate of congenital infection and perinatal infection were 12.5% and 1.85%,respectively.Conclusions CMV infection is the main cause of infant hepatitis and it can also cause neurologic sequelae.The outcome of generalized infection in congenital infection is bad and the mortality rate is high.
