Objective: To improve the understanding of pulmonaryStrongyloides stercoralis. Methods: Two paients were diagnosed with severe infection with pulmonaryStrongyloides stercoralis by respiratory ICU of Xiangya Hospital. The clinical manifestations, laboratory tests, imaging and pathological data were analyzed. Another 87 cases in the literature were reviewed from 1973 to 2013. Results: In the 2 cases, digestive symptoms were the ifrst symptom andStrongyloides stercoralis was found in the lungs. Eosinophils was detected in the 13 death cases by blood routine examination, with 10 cases≤0.05×109/L. Conclusion: The farmers were the main infected people. Patients with basic diseases or with immunosuppression due to long-term glucocorticoid treatment tend to infect and even die atfer the infection withStrongyloides stercoralis. Eosinophil granulocyte reduction shows poor prognosis, which needs early diagnosis and treatment.

OBJECTIVE To explore the expression of Maspin in invasive fungal rhinosinusitis (IFRS) and the value of Maspin in the diagnosis of IFRS. METHODS Forty two cases of fungal rhinosinusitis (FRS) were set as the experimental group, which included 12 cases of IFRS and 30 cases of noninvasive fungal rhino-sinusitis (NIFRS). At the same time, 30 cases of chronic rhino-sinusitis were set as control group. Immunohistochemistry (IHC) was used to detect the expression of Maspin. RESULTS Compared with the control group, the expression of Maspin in FRS group decreased statistically (t=-3.367, P<0.05). The IFRS group, compared with other two groups, had the lowest expression of Maspin (t=-3.390, P<0.05; t=-4.143, P<0.05). By using Maspin score of 5.70 as the cut-off point, the sensitivity and specificity for the diagnosis of IFRS was 91.7% and 88.3% respectively. CONCLUSION The expression of Maspin is very low in IFRS group. Down-regulation of Maspin expression may be a potential indicator for diagnosis of IFRS.

Objective To investigate the effect of Terpinen-4-ol on the proliferation of lung adenocarcinoma A-549 cells and its related mechanism. Methods A-549 cells were treated with different concentrations of Terpinen-4-ol. The inhibitory effect of Terpinen-4-ol on A-549 cells was tested by MTT method. Cell grow ability was determined by CCK-8 colorimetry. The ultrastructure of A549 cells were observed by transmission electron microscopy before and after Terpinen-4-ol treatment. The changes of cell cycle, apoptosis, and the level of intracel-lular calcium were inspected by flow cytometry. Inoculated the lung adenocarcinoma A-549 cells on the nude mice to form transplantation tumor. The experimental nude mice with transplantation tumors were divided into three groups:negative control group,high dose positive con-trol group and low dose positive control group. The mice were given continuously intraperitoneal injection for 10 days, and then the transplan-tation tumors were taken and the size and weight of them were detected. Results After Terpinen-4-ol treatment for 24 h,MTT assay showed that the IC50 value of A549 cells was 0. 067% v/v. The growth curves of positive control groups were significantly smooth than the negative control group. The formation of autophagosome increased after treatment with Terpinen-4-ol. The results of flow cytometry showed that the cell cycle was arrested in S phase,Terpinen-4-ol could induce apoptosis of A549 cell, The intracellular calcium concentrations in positive control groups were significantly higher than the negative control group(P<0. 05). Low dose group and high dose group restrained the growth of the transplantation tumor obviously, and the tumor inhibitory rate were 53. 33% and 77. 76% respectively. Conclusion Terpinen-4-ol has inhibitory effect on the proliferation of A-549 cells in vitro and in vivo.

Objective: To investigate the effect of fractionated radiotherapy on the immune system of mice with subcutaneously transplanted hepatocellular carcinoma. Methods: Logarithmic growth of mouse hepatocellular carcinoma cells Hepa 1-6 were inoculated subcutaneously on the right side of C57BL/6 J mice (1×10⁷ cells /mice). The tumor-bearing mice were randomly divided into control group (Ctrl) and irradiation group (IR), 20 mice in each group. Additionally, 10 healthy mice were set as normal control group. Local fractionated X-ray irradiation of 8 Gy×3 fraction was given to the subcutaneous tumors, and the dose rate was 0.883 Gy/min. At 7 and 14 d after irradiation, the tumor organ index, spleen organ index, spleen pathological changes, and splenic T lymphocyte subsets, B lymphocyte subsets, and NK cells were detected. Results: Compared with Ctrl, at 7 and 14 d after irradiation, the tumor organ index decreased (t=4.649, 26.34, P<0.05), and the percentage of NK cells increased significantly (t=3.952, 3.633, P<0.05). The percentages of CD3+ , CD4+ , CD3+ CD4+ lymphocytes and the ratio of CD4+ /CD8+ lymphocyte decreased at 7 d after irradiation (t=3.193, 3.656, 3.219, 2.641, P<0.05), and the percentage of CD3+ lymphocyte decreased at 14 d after irradiation (t=3.031, P<0.05). But after irradiation, there were no significant changes in spleen organ index, B lymphocyte, CD3+ CD4+ lymphocyte and CD8+ lymphocyte. Conclusions Local hepatoma radiotherapy causes imbalance of lymphocytes in distal spleen of mice and hence reduces immunity, which provides a novel mechanism of radiological immunity damage.

Objective:To investigate the relationship between serum transferrin(TRF)and the characteristics and prognosis of elderly patients with sepsis.Methods:A retrospective analysis was conducted on 49 elderly patients with sepsis treated at the Department of Critical Medicine and the Department of Respiratory and Critical Medicine of the First Affiliated Hospital of Suzhou University between October 2020 and March 2022 who had met the inclusion criteria.These patients were divided into a shock group(n=18)and a non-shock group(n=31); Based on outcomes, they were also divided into a death group(n=16)and a survival group(n=33).Through the random number table method, 30 healthy elderly people from the physical examination center of our hospital were selected as the control group.TRF and ferritin(SF)were measured on the 1st, 3rd and 7th day after admission, and the correlation between TRF and the sequential organ failure assessment score(SOFA)was analyzed.The predictive value of TRF on prognosis was evaluated via the receiver operating characteristic curve.Finally, the influence of multiple factors on prognosis was analyzed using the binary logistic regression model.Results:Compared with the control group at admission, SF levels of elderly patients with sepsis increased[709.20(402.40, 2000.00)μg/L vs.102.05(79.55, 199.75)μg/L, Z=-5.482, P<0.01], but TRF levels decreased[1.43(1.12, 1.72)g/L vs.2.23(1.80, 3.12)g/L, Z=5.395, all P<0.01], with statistical significance.On the 3rd and 7th day, TRF levels in the shock group were lower than in the non-shock group[(1.25±0.35)g/L vs.(1.55 ±0.51)g/L, 1.15(9.68, 1.34)g/L vs.1.56(1.19, 2.03)g/L]( t=-2.186, Z=3.258, P<0.05).There was a linear correlation between TRF and SOFA score on the 1st, 3rd and 7th day( R2=0.177, 0.176, 0.275, all P<0.01).TRF levels in the death group were lower than in the survival group on the 3rd and 7th day( Z=2.208, 3.423, P<0.05 for both).TRF levels on the 3rd and 7th day in elderly patients with sepsis had predictive value in evaluating the prognosis[area under receiver operating characteristic curve( AUC)values=0.696, 0.804, P<0.05, P<0.01].The survival curves based upon the best cutoff values(TRF=1.085 g/L on the 3rd day, TRF=1.330 g/L on the 7th day)between the two groups were statistically significantly( χ2=10.903, 13.318, P<0.01 for both).With TRF<1.085 g/L on the 3rd day, the risk of death in elderly patients with sepsis on the 28th day was 9.388 times the usual risk( OR=9.388, P<0.01), and with TRF<1.330 g/L on the 7th day, the risk of death was 14.625 times the usual risk on the 28th day( OR=14.625, P<0.01). Conclusions:Increased SF in elderly patients with sepsis is not related to disease severity, but the level of TRF is related to disease severity, and the level of TRF on the 3rd and 7th day is related to the prognosis and is an independent risk factor for all-cause death on the 28th day.

OBJECTIVE: To express and purify the extra cellular full-length human apolipoprotein M(ApoM). METHODS: The ApoM gene fragment was amplified from the human liver cDNA library by PCR. The resulting product was cloned into pGEXT vector and sequenced. Then the confirmed canstatin cDNA was cloned into plasmid E.coli JM109 and then transformed into E.coli DL21(DE3) where it was induced to express protein by IPTG. RESULTS: The ApoM gene was cloned by PCR and a 560 bp DNA fragment was shown on the agarose electrophoresis. The cloned gene was sequenced and demonstrated to have the same sequence as that of human ApoM gene in GenBank. Then ApoM cDNA gene fragment was induced by IPTG, and a 24 kD recombinant ApoM protein was tested on SDS-PAGE. CONCLUSION Human ApoM gene is successfully cloned and its recombinant proteins are expressed.

In this study, the current status for breast diseases in a region with high-incidence of cervical cancer were epidemiologically investigated. From March to August, 2009, 17618 women, from Wufeng area of Hubei province, China, were recruited to screen breast diseases by using breast infrared diagnostic apparatus. Other diagnostic methods, such as B-mode ultrasound, X-ray mammography, needle biopsy and pathological examination were, if necessary, used to further confirm the diagnosis. The screening showed that 5990 of 17618 cases (34.00%) had breast diseases, 5843 (33.16%) had mammary gland hyperplasia, 48 (0.27%) had breast fibroadenoma, 11 (0.06%) had breast carcinoma, and 88 (0.50%) had other breast diseases. The peak morbidity of breast cancer was found in the women aged 50-60 ages. The morbidity of breast cancer was significantly increased in women elder than or equal to 50 years old (n=8, 0.157%) in comparison with that in the subjects younger than 50 years old (n=3, 0.024%) (u=2.327, P<0.05). It was shown that the occurrence of breast diseases was concentrated in women aged 20-40 years, while the total morbidity reached its peak at the age of 30 years and then decreased sharply after age of 40. Compared with the patients elder than or equal to 40 years old (n=3289, 27.46%), the morbidity rate of breast diseases was significantly increased in women less than 40 years old (2648 cases, 47.18%; P<0.001). However, there was no significant difference in the morbidity of breast diseases between the age group of 20-29 years and that of 30-39 years (P=0.453), and both of them were high. There was no significant association between the morbidity of breast diseases and cervical cancer. Since the morbidity of breast diseases was higher among young women, more attention should be paid to the screening of breast diseases among young women for early diagnosis.

OBJECTIVETo investigate the correlations between electrogastrogram (EGG) and gastric emptying (GE) in children with functional dyspepsia (FD).

METHODSA total of 51 children with FD and 25 healthy children as control were enrolled into this study. Polygraph ID 4-channel EGG analysis system was used for EGG recording and gastric emptying of solids was studied by using a standardized egg meal labeled with (99m)Technetium sulfur colloid for each subject.

RESULTS(1) Compared with the control group, the percentage of normal slow wave (N%) in the FD group was significantly lower than that of the control group (P < 0.01). Children with FD had higher rates of abnormal EGG, in which 32 cases showed mixed dysrhythmia preprandial and postprandial recordings (62.7%). (2) The two groups had significant difference in ratio of the percentage of preprandial dominant power (DP) to postprandial DP (P < 0.05), it showed that the postprandial DP of the FD group did not increase. (3) The postprandial dominant power instability coefficient (DPIC) as well as preprandial DPIC and dominant frequency instability coefficient (DFIC) in the FD group were increased. The coupling of the slow wave of preprandial and postprandial EGG in the FD group (26.95 +/- 13.69, 26.93 +/- 12.63 respectively) significantly decreased as compared with those in the control group (69.02 +/- 5.15, 70.18 +/- 4.68, P < 0.01). (4) The rate of delayed gastric emptying in the FD group was 23.5%. The results of multivariate Logistic regression analysis showed that there was a significant negative correlation between the delayed gastric emptying and the coupling of the slow wave (partial regression coefficient = -0.513, -0.296 respectively).

CONCLUSIONSPatients with FD had more abnormal findings in EGG than the control group did, and there was a significant negative correlation between the delayed gastric emptying and the coupled response of the slow wave. The abnormal gastric electrical activity may have certain significance in pathogenesis of FD.
