Objective To study the clinicopathological characteristics and the immunohistochemistry of supratentorial parenchymal ependymoma.Methods The clinical and pathological data of 12 patients with supratento-rial parenchymal ependymoma were analyzed,and the tissue slices were immunohistochemically stained.Results The average age of the patients was 29 years old.Most of the lesions occurred in the frontal and parietal lobes,with increased intracranial pressure as the main clinical symptom,including headache,dizziness,nausea and vomiting.The histology showed that the structure of supratentorial parenchymal ependymoma was consistent with that of infratentorial ependymoma.The tumor cells were oval or spindle shaped,diffuse or patchy distribution,small volume,large nuclear staining deep,and were arranged in Flexner-Winterseiner or Homer-Wright.The immunohistochemistry showed that GFAP,vimentin and S-100 were mostly positive,EMA was partly positive and CD56 and NSE were rarely positive. Conclusion Supratentorial parenchymal ependymoma can occur in any part of the supratentorium,mostly in the fron-tal and parietal lobes.It has a specific pathological morphology and immune phenotype,without any characteristic symptoms in clinical,which is easy to be misdiagnosed.Its diagnosis depends on the pathological examination and the prognosis is largely related to whether the surgical resection is complete or not.

Objective To study the changes of TNF-??NO in lung of immature rabbits with meconium aspiration and the relationship with right ventricular pressure. Methods (1)We established mild and severe immature rabbits model of meconium aspiration by endotracheal intubation imbuing meconium 0.6 ml/kg and 4 ml/kg. (2)We measured the right ventricular pressure by right ventricular puncture. (3)level of TNF-? in lung was measured by radioimmunoassay and that of NO was detected by Cr deoxidation. Results Meconium caused pulmonary inflammatory response which was reflected in the increase of cell counts in BALF, peaking at 24 h after instillation [WBC counts (6.06? 0.15 ) ?10 8/L,PMN counts (0.484?0.009)?10 8/L] and recovered by 72 h[(1.93?0.08)?10 8/L,(0 082?0 007)?10 8]. (2)The level of TNF-? in lung of mild group (1.41?0 15) ng/ml increased significantly comparing with control group (0 48?0.07) ng/ml, level of NO (31.9?2.4) ng/ml decreased significantly. Peaked at 16~24 h and recovered to normal by 72 h. the changes of severe group [TNF-?(1.85?0.17) ng/ml, NO(26.4?2.4) ng/ml] were significantly different from those in mild group. (3) At mild group,the right ventricular pressure began to increase at 16 h ( 19.28 ? 0.10 ) mm Hg, peaked at 24 h (26.78?0.14) mm Hg and returned to normal level by 72 h ( 14.18 ? 0.04) mm Hg. The pressure of severe group ( 32.70 ? 0.14 ) mm Hg was significantly higher than that of control and mild group. Conclusions (1)After immature rabbits aspirating meconium, there were remarkable pulmonary inflammatory responses. (2)The level of TNF-? in lung increased, and was correlated with right ventricular pressure,which revealed that MAS with PPHN could be associated with inflammatory response. (3)The level of NO decreased after meconium aspiration, and was lower at severe group. The level of NO was negatively correlated with right ventricular pressure, which indicated that the severe meconium aspiration was companied with severe damage of endotheliocyte which promoted and exacerbated PPHN.

Early newborns,especially premature and very low birth weight infants (VLBWI)are vulnerable to low environmental temperature and/or other factors at birth,they may be insufficient to maintain core body and can cause hypothermia which leads to a variety of disease,affecting their life quality.As the birth rate of premature newborns and VLBWI are increasing in China these years,newborns temperature management have become significant for decreasing newborn's mortality.The main causes for hypothermia are low environmental temperature,insufficient calorie intake,premature newborns,low birth weight and other diseases.Studies shown that the prevention strategies of neonatal hypothermia include:(1) thermal neutral zone;(2) incutators and radiant warmers;(3) plastic hoods and plastic blankets;(4) kangaroo care;(5) breast feeding.

Objective: To investigate the effect and mechanism of Astragalus Injection (Radix Astragali) on acute murine myocarditis caused by Coxsackievirus B 3. Methods: Acute viral myocarditis was induced in 24 Balb/c mice by injection of Coxsackievirus B 3m (CVB 3m ) intraperitoneally. Half of the mice were administered Astragalus Injection(10g/kg?d). Heart and blood samples were obtained from all mice on the 8th day after CVB 3m infection for histopathological study, detection of myocardial perforin expression by reverse transcription polymerase chain reacton(RT PCR) and measurement of serum CK MB level, respectively. Results: (1) Astragalus treated mice showed a significant reduction in myocardial lesion compared with that in untreated mice. (2) Myocardial perforin expression by semi quantitative RT PCR in Astragalus treated mice was much lower than that in controls(1.10?0.07 vs 1.31?0.12, P

Objective To investigate the expressions of proliferating cell nuclear antigen (PCNA), bcl-2, and c-myc protein, and to explore diagnostic value of DNA ploidy in benign and malignant thyroid neoplasms. Methods The expressions of PCNA, bcl-2 and c-myc proteins in 36 cases of thyroid adenomas and 37 cases of thyroid carcinomas were examined by immunohistochemistry technique. DNA ploidy was measured by imaging analysis technique in 8 cases of thyroid adenomas and 17 cases of thyroid carcinomas. Results Among thyroid carcinomas, the positive rates of PCNA (43.02?31.16)% and c-myc protein 89.2% were significantly higher than those of thyroid adenomas (16.15?9.28)% and 50.0% respectively (both P

In order to investigate the rationality of formulation, the absorption behavior of volatile oil from rhizome of ligusticum chuanxiong (VOC) was compared with that of beta-cyclodextrin inclusion complex and self-microemulsifying soft capsule (SMESC). To study the properties of intestinal absorption in situ of SMESC, a series of studies were carried out including the absorption at different concentrations, at different intestinal regions and under different bile secretion conditions. The samples of the perfusion solution were collected at certain intervals. Ligustilide (LD) was chosen as marker component of VOC and the concentrations of which in the perfusion samples were determined by HPLC method. The results demonstrated that the absorption of LD in SMESC was the best and the absorption of VOC increased apparently (P < 0.001). The absorption of LD at concentration of 400 microg x mL(-1) was better than that at 200 microg x mL(-1) and 100 microg x mL(-1) (P < 0.001), while there was no significant difference between the absorption at concentrations of 200 microg x mL(-1) and 100 microg x mL(-1). The absorption of SMESC was not apparently influenced by bile secretion. SMESC could be absorbed in whole intestinal segments. The absorption rate constants (Ka) or apparent permeability coefficients (Papp) of SMESC showed duodenum > jejunum > colon = ileum. Ka and Papp of SMESC at duodenum were significantly higher than that at the other regions of intestine (P < 0.001).

Background and purpose:Radical surgery after neoadjuvant immunotherapy combined with chemotherapy(nICT)in patients with locally advanced esophageal squamous cell carcinoma(LAESCC)has good efficacy and safety,and it can improve the patients'pathological complete remission(pCR)rate,main pathologic response(MPR)rate and R0 resection rate.The prognosis of patients with pCR/MPR after nICT is significantly better compared with patients without pCR.The prognosis of patients achieving pCR/MPR after neoadjuvant therapy has been demonstrated to be significantly better than that of patients with non-pCR/MPR.Therefore,finding predictive factors of pCR/MPR is beneficial for us to screen out the advantageous populations for combination therapy.The aim of this study was to investigate the value of clinical data of patients with LAESCC before and after nICT in predicting the degree of remission of different pathologies after radical surgery following neoadjuvant treatment and to observe the safety of the treatment.Methods:Data of patients with locally LAESCC who underwent radical surgery after nICT from January 2019 to June 2023 at the Affiliated Hospital of Chuanbei Medical College were collected.The clinical data of all patients as well as some blood,inflammation and nutritional indexes of patients before and after neoadjuvant therapy were collected,and the patients were grouped according to the different degrees of pathological remission after neoadjuvant therapy.Data were analyzed by multi-group comparative analysis of variance(ANOVA)and LSD-t post-hoc test.We explored the factors that had an influence on the different degrees of pathological remission,and collected and recorded the patients'adverse reactions during neoadjuvant therapy as well as their eventual surgeries.Results:Data of 62 patients with LAESCC treated with nICT who underwent radical surgery were collected.Only one patient showed grade 4 myelosuppression during neoadjuvant therapy,and the rest of the patients had adverse reactions≤grade 2.The R0 resection rate of the surgery was 98.39%.The present study was compared with the previous studies of LAESCC treated with neoadjuvant chemotherapy followed by radical surgery performed in Affiliated Hospital of Chuanbei Medical College.Compared with the previous studies conducted in our center,no significant difference was observed in terms of operation time,intraoperative bleeding,postoperative hospitalization time and surgical complications.The postoperative pathologic results showed that the pCR rate was 22.58%(14/62),and the MPR rate was 40.32%(25/62).According to the different tumor regression grade(TRG)after surgery,patients were divided into 3 groups of TRG1,TRG2 and TRG3-4,and differences in the platelet distribution width(PDW)before neoadjuvant therapy and the preoperative neutrophil-to-lymphocyte ratio(NLR)after neoadjuvant therapy were statistically significant among the 3 groups(P＜0.05).Further intra-group two-by-two comparisons of PDW before neoadjuvant therapy and NLR before surgery after neoadjuvant therapy were performed for the three groups of patients,respectively,and it was found that the PDW and NLR in the TRG2 group were lower compared with the TRG3-4 group,and the differences were statistically significant(P＜0.05).Conclusion:Radical surgery after nICT treatment in patients with LAESCC can have high R0 resection rate,pCR rate,MPR rate and reliable safety,and the lower PDW of patients before neoadjuvant therapy and the lower NLR of patients before surgery after neoadjuvant therapy predict better pathological remission efficacy.
