Objective To analyze the characteristics of TCM syndromes of children abnormal sweating;To investigate the correlation between diseases and primary and secondary syndromes. Methods Through a multi-center epidemiology investigation, 400 cases were collected to statistically analyze the five TCM syndromes of children abnormal sweating, and characteristics of each syndrome were analyzed. Results In the 400 cases of children abnormal sweating, there were 129 cases (32.25%) of dysfunction of lung-wei pattern, 50 cases (12.50%) of nutrient qi and defensive qi discordance, 84 cases (21.00%) of qi and yin deficiency pattern, 57 cases (14.25%) of dampness heat forced steamed pattern, and 80 cases (20.00%) of qi and yang deficiency pattern. Spontaneous sweating and night sweating were found in the four patterns besides qi and yin deficiency pattern, and night sweating can be mainly found in qi and yin deficiency. Each type is consistent in the syndrome differentiation and cluster analysis. Conclusion Spontaneous sweating and night sweating, each has the certification of yin and yang. Spontaneous sweating can be caused by yin deficiency while night sweating can be caused by yang deficiency. Each pattern of children abnormal sweating has its own syndrome characteristic, which can provide the basis for clinical diagnosis and treatment.

Objective To evaluate the role of calcium channel in the mechanism of the generation and maintenance of bursting firing of substantia nigra pars compacta (SNc) dopaminergic neurons in rats.Methods Using the patch clamp technique,we observed the firing pattern switching features after adding 10 μmol/L N-methyl-D-aspartic acid (NMDA),compared the changes of whole-calcium current and L-type calcium current with or without NMDA,and analyzed the correlation between the generation of burst firing and L-type calcium channel activation.Results After NMDA treatment,the firing pattern of SNc dopaminergic neurons changed to burst firing,which was compromised by a charastistic high plateau potential and series of action potential on it.The current density of L-type calcium current increased significantly after adding NMDA,which,from (2.86 ±0.26) pA/pF (n =28),significantly increased to (3.75 ± 0.18) pA/pF (n =34 ; t =7.52,P =0.002 8).The high plateau potential was almost abolished with the application of verapamil,a specific antagonist of L-type calcium channel.Consiusion NMDA could induce the firing pattern changed to burst firing in SNc dopaminergic neurons,while L-type calcium channel contributes to the process of generation and maintenance of burst firing.

Objective Inhibitor of growth 1 ( ING1 ) gene has been identified as a novel candidate of tumor suppressor gene .Over-expression of ING1 plays well-established roles in numerous cell processes ,inclu-ding DNA repair and cell apoptosis .Our study is to investigate the clinical significances of expression of ING 1 in colorectal cancer ( CRC) .Methods The mRNA level of ING1 in 82 matched samples comprising primary CRC and paired non-cancerous mucosa were detected and compared by quantitative RT -PCR.Then the correlations of mRNA level of ING1 with the clinicopathological characteristics and prognosis of patients with CRC were ana -lyzed.Results (1)In the same matched tissues,the expression level of ING1 was significantly higher in normal tissues than that in cancer tissues.(2)mRNA expression of ING1 was associated with certain clinical -pathologic variables such as tumor infiltrating level ,lymphatic metastasis,distant metastasis and advancing TNM stage .(3) We obtained the expression levels ratio of cancer tissue and normal tissue and found the lower ratio has a lower Disease-Free Survival(DFS)(P<0.0001).(4)ING1,as a candidate of tumor suppressor gene ,remained a sta-tistically-significant prognostic marker in the Cox regression analysis .Conclusion Down-regulation of ING1 may be correlated tightly with the occurrence and progression of sporadic colorectal cancer .Its expression level can be used to predict prognosis of CRC .

Objective To investigate the diagnostic value of CTP-SI in acute stroke less than 9 hours.Methods In present study."one-stop shop"CT examination were performed in 34 patients with symptoms of acute stroke in le88 than 9 hours.We divided patients into two groups according to with and without delayed perfusion on CTP-SI.and compared ASPECTS (Alberta Stroke Program Early CT Score Study)scores on non-contrast CT(NCCT),arterial phase CTP-SI,venous phase CTP-SI with follow-up imaging.The ASPECTS were analyzed on arterial phase CTP-SI and veIlous phase CTP-SI using Wilcoxon rank-sum test.then compared with the follow up imaging ASPECTS using multiple linear regression.Results The median(min-max)scores of ASPECTS on NCCT,arterial phase CTP-SI,venous phase CTP-SI and follow-up imaging were 9.0(6.0-10.0),6.5(1.0-8.0),8.0(3.0-10.0)and 7.0(0-10.0)in group with delayed perfusion,respectively,and 9.0(1.0-10.0),8.5(1.0-10.0),8.5(1.0-10.0)and 8.0 (0～10.0)in group without delayed perfusion respectively.ASPECTs scores measured on arterial phase CTP-SI did not differ from venous phase CTP-SI in group without delayed perfusion ( Z = - 1.00, P =0.317), while there was significant difference in group with delayed perfusion (Z = -3.08, P = 0.002 ).There were significant correlation with ASPECTS scores measured on NCCT, arterial phase CTP-SI and venous phase CTP-SI to follow-up imaging ASPECTS (r =0.899,0.926,0.928,P ＜0.01 ) in group without delayed perfusion; ASPECTS measured in venous phase CTP-SI showed the best correlation to follow-up imaging ASPECTS (r = 0.762, P = 0.004) in group with delayed perfusion.Multiple linear regression showed that the correlation in only venous phase CTP-SI with foUow-up imaging ASPECTS was statistically significant:in group without delayed perfusion, Beta = 0.966, P ＜ 0.001 ; in group with delayed perfusion,Beta = 0.765, P = 0.004. Conclusion Presence of delayed porfusion in CTP-SI is quite important in identifying ischemic penumbra, which plays a critical role in imaging-guided thrombolytie therapy.

Objective To evaluate the shear stiffness of brain by MR elastography (MRE) in healthy Chinese volunteers and to assess the association between the cerebral shear stiffness and age. Methods Brain MRE studies were performed on 105 healthy volunteers. The shear stiffness of brain parencham was measured by local frequency estimation (LFE) algorithm. The differences of the shear stiffness between white matter(WM) and grey matter(GM) were analyzed by independent sample t test; the differences of brain parenchyma shear stiffness between male and female were estimated by independent sample t test. Spearman test was used to analyze the correlation between age and the shear stiffness of parenchyma; the volunteers were divided into two groups (age ≤ 40 and age > 40) and the correlation between age and shear stiffness of parencbyma in each group were analyzed separately. Results The shear stiffness of whiter matter [(23.1±5.7) kPa] was higher than that of grey matter[(11.3±2.6) kPa], and the difference was significant (t = 19.34, P < 0.01). In male, the shear stiffness of WM and GM was (23.4±5.8) kPa and (11.4±2.8) kPa respectively; while in female, it was (22.8±5.6) kPa and (11.1±2.5) kPa respectively. No sex differences were found in the stiffness of white matter or gray matter (t = - 0.534, - 0.606, P > 0.05). An age-dependent trend was observed in the stiffness of grey matter(r =0.315, P < 0.01),while not in whiter matter (r = 0.183, P > 0.05). When the shear stiffness of subjects no more than 40 years old was analysed, the age-dependent trend of shear stiffness was found both in white matter and gray matter(r = 0.251,0.235, P < 0.05); While in subjects over 40 years old, the age-dependent rend of shear stiffness was not found in white matter or gray matter(r = 0.181, - 0.001, P > 0.05). Conclusions The shear stiffness of WM is significantly higher than that of GM. No obvious sex difference was found in the stiffness of brain parenchyma. The shear stiffness of GM increases with age; the age-related increase of shear stiffness of WM was only found in subjects under 40 years old.

time (r = 0. 070, -0.003, -0. 195,0. 177,P 0.05). Conclusions Compared with omnivore's, the shear stiffness of brain parenehyma was lower in vegetarians. The shear stiffness of brain parenchyma may be affected by the diet.

Objective:To compare the efficacy and safety of radium-223 in the treatment of metastatic castration-resistant prostate cancer (mCRPC) patients with and without homologous recombination repair (HRR) gene mutation.Methods:The clinical data of 27 patients with mCRPC bone metastases who received radium-223 therapy from April 2021 to November 2022 in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine were retrospectively analyzed. Among the 27 mCRPC patients, 18 patients carrying HRR gene mutations belonged to the HRD(+ ) group, and 9 patients without HRR gene mutation belonged to the HRD(-) group. The age of patients in HRD(+ ) group was 69.5 (63.8, 77.0) years old, alkaline phosphatase (ALP) was 243.0 (82.8, 301.3) U/L, prostate specific antigen (PSA) was 71.6 (7.3, 329.8) ng/ml, pain score was 3.0 (1.0, 5.0) points. Eastern Cooperative Oncology Group (ECOG) score ranged from 0 to 1 points in 7 cases, and 2 points in 11 cases. In the HRD(-) group, the median age was 72.0 (64.5, 76.5) years old, ALP was 88.0 (67.5, 260.6) U/L, PSA was 19.1 (1.1, 117.8) ng/ml, and pain score was 2.0 (0, 4.5) points. The ECOG score ranged from 0 to 1 in 4 cases, and 2 in 5 cases in the HRD(-) group. There was no significant difference in the above general data between the two groups ( P>0.05). All patients received radium-223 treatment every 4 weeks, no more than 6 times. The changes of ALP, PSA, pain score and hematological adverse reactions were compared between the two groups. Results:In the HRD(+ ) group, the median number of radium-223 treatment was 4.5 (3.0, 5.3) couses, 4 patients (22.2%) completed 6 courses, and 6 patients died of prostate cancer during follow-up. In the HRD(-) group, the median number of radium treatment was 4.0 (2.5, 6.0) couses, 3 patients (33.3%) completed 6 courses, and 1 patient died of prostate cancer during follow-up. There was no significant difference in the number of radium treatment courses between the two groups ( P=0.320). ALP in HRD(+ ) group was 101.8 (61.3, 147.0) U/L after radium-223 treatment, which was significantly lower than that before treatment ( P=0.002). ALP in HRD(-) group was 73.0 (64.0, 113.5) U/L after radium-223 treatment, and it was not significantly different from that before treatment ( P=0.327). The rate of ALP response (ALP decrease >10%) in HRD(+ ) group was significantly higher than that in HRD(-) group [83.3% (15/18) vs. 44.4% (4/9), P=0.037]. PSA was 105.9(5.2, 798.4) ng/ml in HRD (+ ) group after radium-223 treatment, and was 25.6(0.8, 1 031.0) ng/ml in HRD(-) group, and they were not significantly different from that before treatment ( P=0.145, P=0.386). There were no significant differences in the rate of PSA response (PSA decrease>10%) between HRD(+ ) group and HRD(-) group [38.9% (7/18) vs. 22.2% (2/9), P=0.386]. The median pain score of HRD(+ ) group was 3.0 (0, 4.0) points after treatment, which was significantly lower than that before treatment ( P=0.028). The pain score of HRD(-) group was 1.0(0, 3.0) points after treatment, and it was not significantly different from that before treatment ( P=0.129). There was no significant difference in pain relief rate between HRD(+ ) group and HRD(-) group [66.7% (12/18) vs. 44.4% (4/9), P=0.411]. The incidence of at least one hematological adverse event during radium-223 treatment in the HRD(+ ) group was higher than that in the HRD(-) group [77.8% (14/18) vs. 33.3% (3/9), P=0.039]. There was no significant difference in the incidence of grade 1-2 hematological adverse events between the two groups [72.2%(13/18) vs. 33.3%(3/9), P=0.097]. Only 1 patient in the HRD(+ ) group experienced grade 3 anemia during treatment which was recovered after blood transfusion. Conclusions:Compared to mCRPC patients without HRR gene mutation, patients with HRR gene mutations had better ALP response and bone pain relief after radium-223 treatment. The overall incidence of adverse events in the HRD(+ ) group is higher than that in HRD(-) group, and there was no significant difference in grade 1-2 hematological adverse events between the two goups. It is necessary to expand the sample size to further verify the conclusion.

Objective To investigate the role of low dose esketamine in pretreated limb ischemia-reperfusion inju-ry.Methods The rats were divided into sham-operated group(Sham group),ischemia-reperfusion group(I/R group,3 h of ischemia and 2 h of reperfusion),esketamine group(ESK group,ip,5 mg/kg).The plasma con-centrations of creatine kinase(CK)and lactate dehydrogenase(LDH)were measured.The wet/dry weight ratio of skeletal muscle was immediately detected.The gastrocnemius muscle was harvested and the level of malondial-dehyde(MDA)and superoxide dismutase(SOD)was detected by colorimetric assay.The expression of nuclear factor erythroid 2-related factor 2(Nrf2)and heme oxygenase-1(HO-1)were detected by Western blot and im-munohistochemical staining.Results Compared with Sham group,the index of wet/dry weight ratio,MDA,CK,LDH,Nrf2 and HO-1 were all increased,but SOD was decreased in I/R group(P＜0.05).Compared with I/R group,the index of wet/dry weight ratio,MDA,CK and LDH were significantly lower,but SOD and Nrf2 and HO-1 were significantly higher in ESK group(P＜0.05).Conclusions ESK may increase Nrf2 in the nucleus,thereby increase the HO-1 protein as an antioxidant agent.
