Objective To assess the feasibility of integrated 18F-FDG PET-CT for the differentiation of malignancy from benign lesions of heart and pericardium. Methods A total of 23 cases (malignancy∶benign= 13∶10) with cardiac and pericardial lesions confirmed by pathology or clinic were analyzed in the present study. All lesions were evaluated semi-quantitatively using maximum standard uptake values (SUVmax) and SUVmax lesion/blood, and the density of the heart and pericardium lesions and the relationship with surrounding tissues were evaluated. The differences of SUVmax and SUVmax lesion/blood between benign and malignant lesions were analyzed using Mann-Whitney test. Subsequently, the diagnostic sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) were calculated for CT and PET-CT respectively. Results The maximum SUV showed significant difference between malignancy(6. 5 ) and benign ( 1.5 ) ( Z = - 3. 601, P ＜ 0. 01 ), the SUVmax Lesion/Blood of malignancy and benign were 3.4 and 0. 9 respectively, also with significant difference(Z = -3. 600, P ＜0. 01 ). The optimal cut-off value of SUVmax is 3.5-4. 0 and SUVmax Lesion/Blood is 1.3-2. 0. The sensitivity, specificity, accuracy, PPV and NPV of CT and PET-CT were 76. 9％ ( 10/13 ), 100. 0％ ( 10/10) ,87.0％ (20/23), 100. 0％ ( 10/10 ), 76. 9％ ( 10/13 ) and 100. 0％ ( 13/13 ), 90. 0％ (9/10), 95.7％(22/23),92.9％ (13/14),100.0％ (9/9) respectively. Conclusion 18F-FDG PET-CT can correctly differentiate benignity and malignancy of cardiac and pericardial lesions.

Objective To explore the levels of serum 25(OH)D in glomerular disease patients and investigate its influence on the impaired glucose metabolism after treated with glucocorticoid. Methods A total of 61 patients with glomerular disease confirmed by clinical diagnosis and renal biopsy were included in the case group before receiving steroid therapy. 16 cases were selected as control at the same period. Before and six weeks after the treatment of glucocorticoid, all subjects took oral glucose tolerance test (OGT). According to the results of OGT, patients were divided into normal glucose regulation (NGR) group, impaired glucose regulation (IGR) group and steroid diabetes mellitus (SDM) group. Serum 25(OH)D levels were detected with enzyme?linked immunosorbent assay (ELISA), and other clinical data including albumin(Alb), Scr and urine protein were collected. Results (1) Before treated with glucocorticoid, the serum 25(OH)D levels in the control group [(64.09±13.53) nmol/L]were significantly higher than that in NGR group [(50.81 ± 12.44) nmol/L], while the latter was significantly higher than that in IGR group [(42.71 ± 8.09) nmol/L, all P<0.05]. In the glomerular disease patients, 18 cases (29.51%) were 25(OH)D insufficiency and 39 cases(63.93%) were 25(OH)D deficiency. 25(OH)D levels in patients with nephritis were significantly higher than in patients with nephroitic syndrome[(56.94 ± 10.41) nmol/L vs (45.88 ± 11.55) nmol/L, P<0.05]. (2)6 weeks after the treatment, incidence of steroid diabetes in IGR group was significantly higher than that in NGR group (61.11% vs 20.93%, P<0.05). Baseline levels of 25(OH)D in NGR group and IGR group were all significantly higher than that in SDM group [(55.68 ± 13.09) nmol/L, (48.97 ± 9.91) nmol/L vs (40.91 ± 7.82) nmol/L, all P<0.05]. (3)Serum levels of 25(OH)D were positively correlated with serum albumin and serum calcium, and negatively correlated with BMI, urinary protein, cholesterol and the 2 hours postprandial blood glucose. (4)Logistic regression analysis indicated that 25(OH)D<50 nmol/L and HbA1c>5.6% increased the risk of developing steroid diabetes 5.586 and 5.197 times, respectively. Age increased 10 years or insulin resistance index increased one, the risk of occurred SDM increased 2.443 and 2.755 times, respectively. Conclusions Most glomerular disease patients are serum 25 (OH)D deficiency or insufficiency. Low level of serum 25(OH)D is one of the main risk factors of steroid diabetes in patients with glomerular disease when treated with glucocorticoid.

Objective To investigate the effect of electroacupuncture at point Zusanli (ST36) on gastric expression of heat shock protein 70 (HSP70) mRNA in rats with stress gastric ulcer and explore the molecular mechanism of its prevention and treatment of gastric ulcer. Method Fifty-one SD rats were randomly allocated to normal control (normal), stress gastric ulcer (model) and electroacupuncture at point Zusanli (electroacupuncture) groups. A model of stress gastric ulcer was made by cold restraint. From the second day after model making, the electroacupuncture group received electroacupuncture at point Zusanli 20 min once daily for three consecutive days, with left and right points Zusanli alternately needled; the model group, the same restraint treatment as in the electroacupuncture group; the normal group, no treatment. Gastric mucosal ulcer index (UI) was calculated using the GUTH’s method. The pathological morphology of gastric tissue was observed by HE staining. Gastric HSP70 mRNA expression was determined by RT-PCR. Result Different numbers and sizes of obvious gastric mucosal ulcers were observed, UI increased significantly (P<0.001) and HSP70 mRNA expression decreased significantly (P<0.05) in the model group compared with the normal group. The pathological change in gastric tissue improved somewhat, gastric mucosal UI decreased significantly (P<0.05) and HSP70 mRNA expression increased significantly (P<0.01) in the electroacupuncture group compared with the model group. Conclusion Electroacupuncture at point Zusanli can upregulate gastric HSP70 mRNA expression and promote the repair of gastric mucosa injuries in rats with stress gastric ulcer.

Objective To construct Fisher discrminant functions with index of ultrasonography. Methods A total of 48 non-neoplastic ovarian cysts, 137 benign and 120 malignant ovarian tumors were enrolled in this study. Taking ultrasonographic parameters and Doppler blood flow signals as differential diagnosis variable, a diagnosis model was developed using stepwise discriminant analysis. Then a projection and territorial map were drew and the diagnostic ability of the model was verified with substitution method and jackknife. Results ①Univariate analysis indicated that ovarian cysts volume, end-diastolic blood flow velocity (V_(ED)), mean blood flow velocity (V_m), resistance index (RI), pulse index (PI), physical property, echo, shape, boundary, ascites and blood flow signal have statistical difference among the three kinds of ovarian cysts. ②Stepwise discriminant analysis showed that volume, resistance index, physical property, shape and boundary are the independent prognostic variables. The two Fisher discriminant functions were as following: Function 1=0.002volume-4.793 RI+0.468physical property+0.862shape+0.901boundary-4.076, Function 2=0.005volume-1.480 RI+0.851physical property-0.291shape+0.443boundary+0.524. ③The projective positions of three kinds of ovarian cysts at 2D coordinates were clear. ④The sensibility and specificity of mode for diagnosis non-neoplastic ovarian cysts, benign and malignant ovarian tumors was 91.67%, 88.32% and 93.33% with substitution method, and was 91.67%, 86.13% and 93.33% with jackknife method. Conclusion Cysts volume, RI, physical property, shape and boundary are the significant differential prognostic variables. Fisher discriminant analysis can provide a reliable prognostic model for ovarian cysts.

Objective To observe the effect of electroacupuncture(EA) of different acupoints on electroretinogram(ERG) and cerebral visual evoked potentials(VEP) in healthy subjects so as to evaluate the relative specificity of the function of acupoints.Methods A total of 33 healthy adult volunteers were observed in the present study.The subject was asked to lie on a testing bed for a while,two disk electrodes were respectively fixed to the suborbital region and the occiput(the crossing point,5cm apart from the right median line of the head and 5cm above the ear),and the reference electrode was fixed to the medial side of the earlobe for recording ERG and cerebral VEP separately.The testing room was asked to keep faint light during the whole recording process.A flash stimulation(frequency 1 Hz) was applied to the subject's eye(with a distance of about 50 cm between the light source and the tested eye,and the other eye was covered by an eyepatch).EA(0.5 Hz,0.2 ms and 3-4 V) was applied to Guangming(GB 37),Neiguan(PC 6) and Zusanli(ST 36) for 30 min respectively in different testing days(with the interval being 3 days at least).ERG and cerebral VEP were recorded by using Polygraphy(RM-6200).Results Following EA of Guangming(GB 37),Neiguan(PC 6) and Zusanli(ST 36),the changing values(increase and decrease) of the amplitude of b waves of ERG and P100 waves of cerebral VEP were(19.68?12.61)% and(12.84?14.08)%,(6.09?14.06)% and(5.61?8.01)%,(2.39?3.52)% and(5.43?8.22)%,respectively,while those of b waves of ERG and P100 waves of cerebral VEP of GB 37 were significantly bigger than those of PC 6 and ST 36(P

Objective:The topographical mapping technique of cortical evoked potential was used to observe the changes of the functional activities in the primary somatosensory area of cortex (SI) during external stimulation,the immanent relation between external stimulation and topographical mapping of cortical somatosensory evoked potential (CSEP). Methods:33 healthy adult volunteers were under observation. Cerebral electric signal processing system was used to lead CSEP on the scalp. The external stimulation was applied as following:①A soft paintbrush was used to slightly brush the face only. ②Paintbrush was used to slightly brush the lower limb only. ③Paintbrush was used to slightly brush the trunk only. ④Paintbrush was used to slightly brush the lower limb or the trunk or the Gallbladder Meridian (GBM) and passing the upper arm by imitating the speed of meridian transmission phenomenon respectively. Results:①Evoking responses appeared in the foot areas in SI,without meridian transmission phenomenon when brushing the face,lower limb or trunk only. ②Healthy volunteers were offered imitation of sensation conduction along the GBM as well as brushing through the upper arm in addition,while,the results showed that the evoking responses appeared in the foot,the upper arm and the face representation area of SI simultaneously. Conclusion:The external stimulation along the meridian course was able to change the distribution of evoking responses in SI during stimulating acupoint. But the local stimulating on face,lower limb or trunk can not change the distribution of CSEP. The results provided experimental evidence for the supposition that 'activation in sequence in periphery'was the decisive factor for the formation of meridian transmission phenomenon.

The Chinese and English published literature regarding the effects of acupuncture on microcirculation in recent years were analyzed, and it was found out that the theory of TCM meridian had subtle connection with microcirculation on structure and function, which could provide a possible breakthrough for the research of meridian essence. Acupuncture, through multiple links, multiple paths and multiple levels, could regulate microcirculation under physiological or pathological condition, which was a bidirectional benign adjustment function, and reflected the characteristic of acupoint specificity. Due to many shortcomings in the current studies, studies with rigorous design, large sample size and multicenter are expected in the further to make a standard systematized research.

Multiple myeloma is common in the older population and is treated mainly with chemotherapy. However, chemotherapy-related side effects imitate the clinical manifestations of Sheehan's syndrome, which leads to misdiagnosis and missed diagnosis, particularly for older patients without a clear history of postpartum hemorrhage. Therefore, when older women with malignant myelomas show refractory hyponatremia and gastrointestinal disorders while under chemotherapy, a diagnosis of Sheehan's syndrome should be considered. The early detection of the disorder will guarantee timely individualized treatment.
