OBJECTIVETo study the effect of Fuzheng Sanjie recipe in regulating tumor-associated macrophages (TAMs) in Lewis lung cancer mice.

METHODEfforts were made to establish the Lewis lung cancer mouse model, weigh tumors and calculate the anti-tumor rate. The immunohistochemical method was used to examine the infiltration degree of CD68 + in tumor tissues in each group. ELISA was used to examine the content of IFN-γ, TGF-β, IL-4, IL-13, IL-6, IL-10, IL-12, TNF-α in mice serum.

RESULTCompared with the tumor-bearing model group, all of the other groups showed higher tumor inhibition rates, i. e. 50.28% for the DDP group, 34.37% for the TCM-preventing group and 66.76% for the Chinese and western medicine group, with statistical difference (P < 0.05), but without statistical difference in the infiltration degree of CD68+. The expressions of the IFN-γ, IL-6, IL-12 in tumor-bearing groups were lower than that in the blank control group, but with higher contents of IL-4, IL-13, TGF-β. Intervened with different drugs, there were significant differences in content among some relevant cytokines (P < 0.05), as well as statistical differences among the TCM prevention group, the Chinese and western medicine group and the tumor-bearing control group (P <0. 05) , but without statistical difference in TNF-α and IL-10 content from the tumor-bearing control group (P < 0.05).

CONCLUSIONFuzheng Sanjie recipe could reverse the immune remodeling effect and control the tumor growth by down-regulating the expressions of IL-4, IL-13, TGF-α in lung cancer immune microenvironment and up-regulating the expression of IFN-γ.

OBJECTIVETo investigate the clinicopathological features of infantile cytomegalovirus hepatitis.

METHODLiver biopsies from 30 cases of infantile cytomegalovirus hepatitis were observed under optical microscope and electronic microscope.

RESULTThe main clinical manifestations were jaundice, splenohepatomegaly and hypohepatia. Laboratory test showed dysfunction of liver, high level of CMV DNA, and high titer of anti-CMV antibody. Imaging examination demonstrated hepatomegaly. The histological changes were hepatocellular degeneration, necrosis, apoptosis, and fibrosis. The histological characteristics of cytomegalovirus hepatitis, including intranuclear inclusions in multinucleated giant cells and pseudo-lumens, were also observed under optical microscope. In addition, virion was observed in the nuclei and cytoplasm of hepatocytes under electronic microscope.

CONCLUSIONThe viral DNA and serological tests have limited utility for the diagnosis of infantile cytomegalovirus hepatitis, and the final diagnosis depends on histopathology.

OBJECTIVETo study the features of histopathologic and ultrastructural pathologic changes of liver biopsy in patients with infantile cholestatic disease, and to investigate its diagnostic significance combining with the clinical data.

METHODSThirty-six children diagnosed as infantile cholestatic disease and received liver biopsy in Chongqing Medical University Children's Hospital from Jun 2007 to Oct 2008 were enrolled and the pathologic and ultrastructural pathologic changes of liver were analyzed.

RESULTSMorphologic changes under light microscope in liver tissues included hepatocyte swelling, hepatocyte denaturation, hepatocyte necrosis, multinucleated giant cell formation, bile duct proliferation, fiber tissues proliferation and inflammatory cells infiltration in liver lobules and portal regions. The characteristics of cholestasis including intralobular cholestasis, acinus formation, feather-like cytoplasmic filaments and bile stasis in bile canaliculi were observed. The morphologic changes of biliary atresia were observed in 7 cases whose image investigations showed no obstruction of biliary tract. Nuclear changes, resolution of cytoplasm, inflammatory cell infiltration, collagen fiber proliferation and increased number of lysosomes were observed under electromicroscope. Two cases of glycogen storage disease, 1 case of Niemann-Pick disease and 1 case of lipid storage disease with unknown cause were confirmed by the combination of histological changes and clinical manifestations.

CONCLUSIONCommon pathologic changes of liver tissues existed under light microscope or electroscope. The diagnosis of hereditary metabolic disorders could be made increasingly by application of these two technologies in clinical practice. It is difficult to diagnose biliary atresia in early childhood by image investigations and the pathological changes of liver tissues are helpful.

OBJECTIVETo explore the appropriate temperature of the kalium-verapamil-propranolol (KVP) cardioplegia by observation of the effect on the function of the immature rat heart.

METHODSIsolated hearts from immature rats were perfused by Langendorff method, and assigned to 1 of the following 5 groups (n = 6-8): control, continuously perfused for 170 min at 36 degrees C, normal temperature, normal perfused for 20 min, changed to perfuse with KVP for 3 min then no perfusion 87 min (ischemia 90 min), followed by 60 min reperfusion. 3 groups of low temperature, perfused for 15 min, cool down to 32 degrees C, 28 degrees C and 24 degrees C especially in 5 min, and at 20th min. heart rate (b/min), tension (g), contraction force (g), peak systolic velocity (dT/dt(max)), peak diastole velocity (dT/dt(max)), coronary flow (Drop/min) were monitored during the whole perfusion.

RESULTSCompared to control group, the heart tension increased after 50 min KVP ischemia. The protection of KVP in normal temperature (36 degrees C) was better than lower temperature (32 degrees C, 28 degrees C, 24 degrees C) such as reducing bad contraction, keeping normal myocardium tension,recovering heart rate, recovering the fuction of contraction force and protecting the coronary flow.

CONCLUSIONThe KVP cardioplegia in normal temperature has the better effect than that in hypothermia to protect the immature heart.

Objective:To investigate the radiological presentations in relation to different ages in scoliosis associated with Chiari malformation typeⅠ(CMI).Methods:A retrospective analysis was performed on 80 patients diagnosed with scoliosis associated with CMI from June 2010 to June 2018, who were classified into three groups according to their age: Children(age≤10 years), Adolescents (age 11-18 years) and Adults (age≥19 years). Curves were classified into typical and atypical patterns in the coronal plane. The coronal and sagittal radiographical parameters were measured in the three groups. Moreover, cerebellar tonsillar descent and syringomyelia patterns were measured on MRI, and the parameters among the three groups were compared statistically.Results:The incidence of atypical curve patterns in Children (10 patients), Adolescents (44 patients) and Adults (26 patients) was 30.0%, 15.9%, and 50.0%, respectively (χ 2=2.654, P=0.265). There was no statistical difference in the distribution of curve patterns among CMI patients with different age. In the coronal profile, Cobb angle ( F=16.751, P<0.001) and flexibility ( F=3.285, P=0.044) of main curve, Cobb angle of secondary curve ( F=9.805, P<0.001) and coronal balance(CB) ( F=5.249, P=0.007) showed statistical difference. The elderly patients tended to have larger Cobb angle of main and secondary curve with worse flexibility of main curve, and CB in Adolescents was better than the other two groups. In the sagittal profile, TK ( F=4.324, P=0.017), LL ( F=4.590, P=0.013), PI ( F=5.501, P=0.006), and PT ( F=3.220, P=0.045) showed statistical difference in the three groups, which were increasing significantly with aging. MRI parameters showed that younger patients were more likely to have a higher degree of cerebellar tonsillar descent (χ 2=18.479, P<0.001) and distended syringomyelia (χ 2=23.074, P=0.003). Conclusion:With aging, Cobb angle of main curve is progressive, and the flexibility is worse, suggesting that early surgical intervention should be performed to reduce the risk of surgery. In addition, cerebellar tonsillar descent and syringomyelia in elderly patients are milder than young patients, indicating that there might be spontaneous remission.

OBJECTIVETo investigate the characteristics of breakthrough bleeding in adult patients with severe hemophilia A (SHA) receiving low- and intermediate-dose FVIII for tertiary prophylaxis and explore the factors affecting the outcomes of the treatment.

METHODSForty-nine patients (mean age 31.53∓7.33 years) with SHA receiving tertiary prophylaxis FVIII treatment were divided into low-dose group (n=15) and intermediate-dose group (n=34). The data including clinical bleeding phenotype (Pre?AJBR), 72 h FVIII trough activity, and Functional Independence Score in Hemophilia (FISH) were recorded in all the patients, and Hemophilia Steward APP was used to record the bleeding episode and the treatment data. All the patients were followed up for at least 6 months.

RESULTSIn the low-dose and intermediate-dose groups, the number of joint bleeding (AJBR) episodes were 18.79∓13.03 and 9.28∓7.02 per year (P=0.016), and the proportions of spontaneous bleeding were 75.0% and 47.7%, respectively. The proportions of patients with target joint were 80% and 44%, target joint bleeding occurred in 59% and 41%, and cataract bleeding after 0-12 h of prophylactic injection occurred in 4.86% and 5.18% of the patients with a median breakthrough bleeding time of 40.08 h and 46.08 h (P=0.008), respectively. The proportions of patients with 72 h FVIII trough activity <1% were 44.4% and 34.8% in the two groups, respectively. AJBR was negatively correlated with the preventive dose consumed (r=-0.57, P=0.000, n=49) and FISH, but positively correlated with Pre-AJBR in the two groups (P<0.05).

CONCLUSIONTertiary prophylaxis with low- and intermediate-dose FVIII is not sufficient to achieve the goal of preventing progression of joint disease in Chinese adult patients with SHA. Although the prophylactic dose is the most important factor to affect the treatment efficacy, other non-factor approaches may also help to improve the efficacy of the treatment.
