The contents of copper, iron, zinc, manganese and chronium in human milk, taking from different lactation period (1-90 days), and cow's milk -were determined by atomic absorption spectrophotometry.We found that the concentrations of copper, iron, zinc and manganese in human milk declined during tie course of lactation, and that of copper, iron, zinc and chroninm in human milk were higher than that in cow's milk. When comparison of the essential trace elements intake of breast feeding and cow's milk feeding infant with the values recommended, the breast feeding was more optional than cow's milk feeding from nutritional point of view. Our results offered the scientific evidence for breast feeding and suggested that additional essential trace elements should be given to cow's milk when it was used to fed infant.

Human colostrum and milk collected at different times during the first six months of lactation from 301 subjects were tested for the levels of SIgA, IgM, IgG, C3, C4, lactoferrin and lysozyme by the technique of radial immunodiffusion. These kinds of immunoglobulins in colostrum and milk were detected, however the SIgA was highest among immunoglobulins in colostrum, which acounted for 89.8%.The average level of SigA on the first day of postpartum was 3152.5 mg/dl and exceeded those in the serum by 13-fold. It was suggested that breast-feeding may be crucial for the newborns before their mucosal immune system has been established. The average levels of C3 and C4 on the first day of postpartum were 99.7mg/dl and 65.9mg/dl respectively, reaching the normal serum level. Lactoferrin was as high as 1228.7mg/dl in the colostrum of the first day of lactation. The concentration of lysozyme was 944.2ug/ml on the first day of postpartum, which was about 429 times higher than that of cow milk. Using Holder pasteurization (62.5℃, 30 minutes), the SIgA and lysozyme activity of the milk could be reduced by 29.7% and 8.3% respectively, but a lot of anti-infective factors still remained in milk. So pasteurization may be useful for the sterilization of stored human milk.

Objective To investigate the relationship between the efficacy of autologous epidermal grafting and the levels of epidermal cytokines in vitiligo. Methods A total of 57 patients with stable vitiligo receiving autologous epidermal grafting were included in this study. Before grafting, 17 patients were irradiated with narrow-band UVB on vitiliginous sites. Suction blister fluid was collected from the recipient site (vitiligous lesions) and donor site (normal skin) in these patients (including the 17 patients irradiated with NB-UVB). ELISA was used to detect the levels of endothelin-1 (ET-1 ) and stem cell factors (SCF) in suction blister fluid. Clinical efficacy was evaluated through a 3-month follow-up. Resttlts Among these 57 patients, 45 successfully responded to autologous epidermal grafting. In these 45 patients, the levels of ET-1 and SCF in vitiligous lesions were 728.97±286.12 ng/L and 329.97±114.13 ng/L respectively, significantly higher than those in nomal skin (503.16±251.44 ng/L, 224.73±107.91 ng/L, t = 5.443, 5.897, respectively, both P < 0.05 ). In those who responded poorly, significant difference was also observed in the level of SCF between the normal skin and vitiligous lesions (309.00±163.89 ng/L vs 204.22±83.25 ng/L, t = 3.03, P < 0.05), but not in the level of ET-1. Increased level of ET-1 was observed in both vitiligous lesions and normal skin of patients who responded well compared to those who responded poorly, while no difference was noticed in the level of SCF between these two groups of patients. The level of ET-1 was statistically higher in vitiligous lesions in patients exposed to NB-UVB than in those without exposure (t = 1.44, P > 0.05). In those patients who responded successfully, the level of ET-1 was lower in the 15 patients exposed to NB-UVB compared to the other 30 patients without exposure (548.48±230.22 ng/L vs 794.60±278.72 ng/L, P<0.05); no significant difference in the level of SCF was noted. Conclusions ET-1 and SCF may both play important roles in the repigmentation of vitiligo, with ET-1 exerting a more important role.

Objective To observe the effect of Juli Sanjie Pill(JSP) on estrogen receptor(ER)? and ER? expression in the myometrium and hysteromyoma tissue,and to explore the correlation of ER? and ER? expression levels with the incidence of hysteromyoma. Methods Forty hysteromyoma patients were divided into two groups: 20 patients with operative indications after oral use of JSP and asking for operation,were enrolled in the treatment group,and other 20 patiens without mediation of medicine but asking for operation were in the control group.The ER? and ER? expression levels in hysteromyoma tissue and the surrounding normal myometrium of the two groups were detected by radioimmunoassay.Results There presented the expression of ER? and ER? in the hysteromyoma tissue and the surrounding normal myometrium of the two groups,and the levels in the hysteromyoma tissue were higher than that in the myometrium(P0.05).Conclusion The incidence of hysteromyoma is correlated with the local expression of ER? and ER? in the uterus.The therapeutic mechanism of JSP for hysteromyoma is probably related with the decrease of ER? and ER? expression levels in hysteromyoma tissue and with the decrease of ER? level in the surrounding normal myometrium.

OBJECTIVE:To better carry out the pharmaceutical services in outpatient pharmacy,and provide reference for the safe,effective and rational drug use of outpatients. METHODS:Questionnaires were designed based on the related information pro-vided by consultation services of outpatient pharmacy in our hospital and referring to the related literatures to randomly select and investigate the patients of outpatient pharmacy in our hospital,and the results were statistically analyzed. RESULTS:There were to-tally 450 questionnaires,involving 417 valid questionnaires with the effective recovery of 92.67%. The questions about pharmaceuti-cal service of surveyed patients were dosage and precautions,respectively with the number of 254(60.91%)and 251(60.19%);followed by functions and indications,with the number of 234 (56.12%);besides,there were also with widespread concerns, such as drugs efficacy,medication time,and medication of elderly,children and pregnant women,etc. Among the surveyed pa-tients,20.75% were blind medication;89.45% thought the pharmacists’guidance was helpful for medication;there were still 21.35% without pharmacists’medication guidance. CONCLUSIONS:The survey shows the poor awareness of rational drug use and lacking knowledge of drugs in outpatients,they are eager for medication guidance from professional pharmacists. However,the pharmaceutical service in outpatient pharmacy needs to be improved. It is suggested to actively promote the pharmacy services by implementing points medication,adopting red and blue for warning labels,providing comprehensive drug counseling services and carrying out rational drug use education,etc.

Objective:To observe the image characteristics of optical coherence tomography (OCT) in patients with primary vitreoretinal lymphoma (PVRL).Methods:A retrospective clinical study. Thirty-two eyes of 19 patients diagnosed with PVRL by vitreous pathology in the Department of Ophthalmology, Beijing Tongren Hospital from September 2016 to October 2019 were included in this study. There were 7 males and 12 females. The median age was 56 years. The mean time from symptom onset to final diagnosis was 6.1±3.8 months. The first diagnosis was uveitis in 12 cases (63.1%, 12/19), retinal vein occlusion in 2 cases (10.5%, 2/19), central retinal artery occlusion in 1 case (5.3%, 1/19), and suspected PVRL of camouflage syndrome in 4 cases (21.1%, 4/19). Routine ophthalmic examination and frequency-domain OCT examination were performed in all the patients, and typical images were stored for analysis. According to the examination results, PVRL OCT signs were divided into vitreous cells, inner retinal infiltration, outer retinal infiltration, retinal pigment epithelial (RPE) infiltration, sub-RPE infiltration, and subretinal fluid.Results:Vitreous cells were found in all eyes (100.0%, 32/32). RPE infiltrated were observed in 19 eyes (59.4%, 19/32), RPE infiltration in 16 eyes (50.0%, 16/32), outer retinal infiltration in 8 eyes (25.0%, 8/32), inner retinal infiltration in 16 eyes (50.0%, 16/32), and subretinal fluid in 4 eyes (12.5%, 4/32).Conclusions:PVRL OCT signs can involve vitreous and retinal anatomical levels, including vitreous cells, inner retinal infiltration, outer retinal infiltration, RPE infiltration, sub-RPE infiltration and subretinal fluid. The same patient can show multiple signs at the same time.

Objective:To investigate the characteristics of Parkinson's disease (PD)combined with orthostatic hypotension (OH)and the impact of the condition on cognitive function.Methods:A total of 210 PD patients admitted to Beijing Tiantan Hospital were consecutively enrolled.Demographic data and clinical characteristics were recorded.Patients were divided into the PD with OH (PD-OH)group and the PD without OH (PD-NOH)group based on blood pressure values measured in both the supine and upright positions.Cognitive function of PD patients was evaluated using the Mini-Mental State Examination (MMSE)and Montreal Cognitive Assessment (MoCA)scales.Results:Of 210 PD patients, 68 (32.4%)had OH.Patients in the PD-OH group had a higher mean age (69.7±8.9 years vs.62.1±11.3 years), longer disease duration [5.0 (3.0-8.0)years vs.4.0 (2.0-6.0)years], a higher incidence of diabetes (30.9% vs.17.4%), higher levels of fasting blood glucose (5.3±1.1 mmol/L vs.5.0±1.0 mmol/L)and glycated hemoglobin A1c (6.1±0.9% vs.5.7±0.7%), and more advanced Hoehn-Yahr staging [stage 2.5 (2.0-3.0) vs.stage 2.0 (1.5-2.5)]than the PD-NOH group ( P<0.05). The total scores of the MMSE and MoCA scales were lower in the PD-OH group than in the PD-NOH group (25.1±4.9 scores vs.26.8±4.0 scores, 19.4±5.4 scores vs.21.4±5.3 scores, P<0.05). A comparison of each cognitive domain of the MMSE scale between the two groups revealed that the scores of attention and calculation (3.7±1.7 scores vs.4.2±1.3 scores), delayed recall (2.1±1.0 scores vs.2.5±0.8 scores)and visuospatial ability (0.6±0.5 scores vs.0.7±0.5 scores)were lower in the PD-OH group than in the PD-NOH group ( P<0.05). A comparison of each cognitive domain of the MoCA scale between the two groups displayed that the scores of visuospatial and executive function (2.4±1.6 scores vs.2.9±1.7 scores)and delayed recall (1.3±1.4 scores vs.2.3±1.6 scores)were lower in the PD-OH group than in the PD-NOH group ( P<0.05). Logistic regression analysis showed that age ( OR=1.061, 95% CI: 1.022-1.102, P=0.002)and score of delayed recall of the MoCA scale ( OR=0.690, 95% CI: 0.498-0.955, P=0.025)were independent related factors for PD-OH. Conclusions:Compared with patients without OH, PD-OH patients are older and have a longer duration, increased disease severity, and a higher incidence of and more serious diabetes mellitus.Age is an independent related factor for PD-OH.Cognitive function is significantly impaired in PD-OH patients, and delayed recall is an independent related factor for PD-OH.

Objective To investigate the clinical diagnostic value of serum procalcitonin(PCT),D-dimer (DD),C-reactive protein(CRP)in acute-on-chronic liver failure(ACLF). Methods 124 ACLF patients, 63 chronic hepatitis B patients,32 chronic hepatitis C patients,24 chronic hepatitis E patients and 60 healthy controls from the second affiliated hospital of Nanchang University were enrolled in this study.PCT was detected by a sandwish immunodetection method. D-dimer was detected by Latex Turbidimetry. CRP was detected by rate nephenometry. The detection results were used for analyzing the clinical diagnostic value of ACLF with infection. Results(1)The level of PCT,DD and CRP in ACLF group were significantly higher than non-ACLF group and healthy controls(P<0.05).The levels of PCT,DD and CRP in the infection group were significantly higher than non-infection group(P<0.05).(2)The positive rates of PCT,DD and CRP in the infection group were 93.24%, 78.38%,89.19%,which were significantly higher than the non-infection group and healthy controls respectively (P < 0.05).(3)The sensitivity(93.24%)and specificity(90.00%)of PCT were the highest among all indexes. (4)The area under the ROC curve of PCT,DD,CRP were 0.892,0.715,0.755,respectively.PCT had the highest diagnostic value. Conclusion The levels of serum PCT,DD and CRP have a significant clinical value for the early diagnosis of ACLF with infection.
