ABSTRACT

The fruits of Eucalyptus globulus Labill. are known to have a plenty of medicinal properties, such as anti-tumor, anti-inflammatory, and immunosuppressive activity. Our previous study found that the phloroglucinol-sesquiterpene adducts in the fruits of E. globulus were immunosuppressive active constituents, especially Eucalyptin C (EuC). Phosphoinositide 3-kinases-γ (PI3Kγ) plays a pivotal role in T cell mediated excessive immune responses. In this study, EuC was first discovered to be a novel selective PI3Kγ inhibitor with an IC

ABSTRACT

Objective:To compare the intervention effect of Case Management and Group Work in discharged schizophrenic patients. Methods:A total of 100 patients with stable schizophrenia who were discharged from a mental health center in a district of Shanghai were randomly divided into two groups: case management (CM) and group work (GW), with 50 patients each. The group work method and case management model were used, respectively, to provide psychiatric symptom assessment,medication guidance,functional training,health education and other services to for 6 months. Both Positive and Negative Syndrome Scale (PANSS) and Social Disability Screening Schedule (SDSS) were used for assessment at the beginning and at the end of 6th month. The conditions and the improvement of social function of these two groups were compared. Results:Before and after the intervention,the positive symptom score,negative symptom score and PANSS total score of the CM group were decreased,the difference was statistically significant(t=4.214,3.926,3.929,P<0.001). The PANSS score of the GW group only had significant difference before and after the general pathology and the total score(t=2.195,2.466,P<0.05).There were significant differences in SDSS scores between these two groups before and after the intervention(P<0.001). There was a significant difference in the reduction rate of positive symptom score between the two groups(z=-2.937,P<0.05). There was also a significant difference in the reduction rate of SDSS scores(z=-3.834,P<0.001). Conclusion:Both case management and group work can stabilize the condition of schizophrenia patients and improve social function,but there is a slight difference in the emphasis of the two methods.

ABSTRACT

Background@#Pilomatrixoma is a benign tumor that originates from the hair follicle matrix. It usually presents as a hard, slow growing, solitary mass that can be easily misdiagnosed as other skin masses. The aim of this study was to clinically analyze a case series of pilomatrixoma in pediatric patients from Korea. @*Methods@#A total of 165 pediatric patients from 2011 to 2018 with a histological diagnosis of pilomatrixoma were included. A retrospective review was performed using the electronic medical records, including patient demographics, number and location of the mass, clinical and imaging presentation, and postoperative outcomes. @*Results@#There were 61 male and 104 female patients with 152 solitary and 13 multiple pilomatrixomas. Among solitary pilomatrixomas, the lesion commonly occurred in the head and neck (84.2%), followed by upper limbs (11.2%), lower limbs (3.3%), and trunk (1.3%). The pilomatrixoma lesion presented as the following types based on our clinical classification: mass (56.02%), pigmentation (25.31%), mixed (12.65%), ulceration (4.82%), and keloid-like (1.2%). Ultrasonography showed a high positive predictive value (95.56%). There were no specific complications observed except for two cases of recurrence. @*Conclusion@#Pilomatrixoma has various clinical feature presentations and commonly occurs in the head and neck. Ultrasonography is a helpful diagnostic tool. Surgical removal of the lesion is the main treatment method with a low recurrence rate.

ABSTRACT

BACKGROUND@#Cerebrospinal fluid (CSF) has been demonstrated as a better source of circulating tumor DNA (ctDNA) than plasma for brain tumors. However, it is unclear whether whole exome sequencing (WES) is qualified for detection of ctDNA in CSF. The aim of this study was to determine if assessment of ctDNA in CSF by WES is a feasible approach to detect genomic alterations of glioblastoma.@*METHODS@#CSFs of ten glioblastoma patients were collected pre-operatively at the Department of Neurosurgery, Sun Yat-sen University Cancer Center. ctDNA in CSF and genome DNA in the resected tumor were extracted and subjected to WES. The identified glioblastoma-associated mutations from ctDNA in CSF and genome DNA in the resected tumor were compared.@*RESULTS@#Due to the ctDNA in CSF was unqualified for exome sequencing for one patient, nine patients were included into the final analysis. More glioblastoma-associated mutations tended to be detected in CSF compared with the corresponding tumor tissue samples (3.56 ± 0.75 vs. 2.22 ± 0.32, P = 0.097), while the statistical significance was limited by the small sample size. The average mutation frequencies were similar in CSF and tumor tissue samples (74.1% ± 6.0% vs. 73.8% ± 6.0%, P = 0.924). The R132H mutation of isocitrate dehydrogenase 1 and the G34V mutation of H3 histone, family 3A (H3F3A) which had been reported in the pathological diagnoses were also detected from ctDNA in CSF by WES. Patients who received temozolomide chemotherapy previously or those whose tumor involved subventricular zone tended to harbor more mutations in their CSF.@*CONCLUSION@#Assessment of ctDNA in CSF by WES is a feasible approach to detect genomic alterations of glioblastoma, which may provide useful information for the decision of treatment strategy.

ABSTRACT

The purpose of the present study was to investigate the effects of forkhead box O4 (FOXO4) on the senescence of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs). The hUC-MSCs were induced to senescence by natural passage, and FOXO4 expression was inhibited by lentiviral shRNA transfection. The hallmark of cell senescence was analyzed by β-galactosidase staining, and the cell viability was assayed by CCK-8 method. Flow cytometry was used to investigate the apoptosis of hUC-MSCs. The expression levels of Bcl-2, Bax, FOXO4, interleukin 6 (IL-6) and cleaved Caspase-3 were detected by qPCR and Western blot. Immunofluorescence staining was used to detect FOXO4 expression. The amount of IL-6 secreted by hUC-MSCs was detected by ELISA. The results showed that, compared with the passage 1, senescent hUC-MSCs showed up-regulated expression levels of Bax and FOXO4, down-regulated expression levels of Bcl-2 and cleaved Caspase-3, and increased IL-6 mRNA expression and secretion. FOXO4 inhibition in senescent hUC-MSCs promoted cell apoptosis, reduced cell viability, and inhibited the mRNA expression and secretion of IL-6. These results suggest that FOXO4 maintains viability and function of senescent hUC-MSCs by repressing their apoptosis response, thus accelerating senescence of the whole cell colony.

ABSTRACT

Purpose To evaluate the value of immunohistochemical stain (IHC) in the diagnosis of helicobacter pylori (HP) -associated gastritis with gastric biopsy tissue. Method239 cases of gastric biopsy were selected. All patients had14 C urea breath test (UBT) at the time of gastric biopsy. IHC for HP was performed with the biopsy tissues. The results were compared with gold standard results. Gold standard was established according to the Chinese Fourth National Consensus report on HP infection with modification. It was considered positive if two or more of the three test results were positive, including IHC, UBT, and HE. Results 239 gastric biopsy specimens fit the criteria. Compared with the gold standard, the sensitivity and specificity value of IHC stains were 97.3% and 100.0% respectively, higher than 91.1%, 81.9% of 14 C UBT, and 80.4%, 92.9% of HE stain respectively. The14 C UBT showed 9.6% false positive rate, and 4.2% false negative rate. Conclusion IHC is a valuable test in the diagnosis of HP-associated gastritis, and it should be recommended for routine histopathologic diagnostic workup if HP gastritis is clinically suspected or chronic active gastritis is identified in the biopsy tissue.

ABSTRACT

As known,simultaneous determination of various chemical indicators is one of the future trends in quality control of traditional Chinese medicines because of the extremely complex chemical compositions. This project is to screen the quality markers that can accurately control the quality of the Bufonis Venenum by exploring the intrinsic correlation of components. In this study,venom of Bufo bufo gargarizans from 17 different sources were used as research samples,and the contents of 7 bufogenin were determined by HPLC-DAD. Then,the data obtained were analyzed by Spearman correlation analysis and principal component analysis( PCA). In addition,a stepwise regression analysis was used to establish a predictive model for the contents of the seven bufogenin components( independent variable) and the total contents of the bufogenin( dependent variable). The results indicated that there is a significant positive correlation between the contents of telocinobufagin and cinobufotalin,and there is a significant positive correlation between the contents of bufalin,cinobufagin and resibufogenin. In contrast,the contents of telocinobufagin and cinobufotalin are negatively correlated with the contents of bufalin,cinobufagin and resibufogenin. However,the correlation between gamabufotalin and bufotalin and other components are not obvious. Furthermore,further study found that there is a correlation between the sum of the contents of bufalin,cinobufagin and telocinobufagin and the total contents of the bufogenin. In fact,the application of bufalin,cinobufagin and telocinobufagin as the quality control indicators of the Bufonis Venenum can better reflect the quality characteristics of the Bufonis Venenum compared with the previous quality control indicators. The conclusions will provide a reference for the revision of the quality standards of the Bufonis Venenum.

ABSTRACT

Objective:To investigate the mid-and long-term clinical effects of tricuspid valvuloplasty with the implantation of an artificial plastic ring.Methods:Data of 677 patients who had functional tricuspid regurgitation and left cardiac valve disease and underwent tricuspid valvuloplasty and left cardiac valve surgery were retrospectively. Among these patients, 353 underwent simple suture annuloplasty (group A) while the rest 324 patients underwent artificial plastic ring annuloplasty (group B). The two-year and more-than-two-year clinical and ultrasonocardiograph (UCG) follow-up data of the two groups were obtained and compared.Results:A total of 600 patients (88.6%) completed the long-term follow-up (more than two years). The two-year follow-up showed no significant difference in the incidence of mild tricuspid regurgitation between the two groups (82.2% vs. 92.7%, P=0.37). However, there were significantly more cases that developed into moderate to severe tricuspid regurgitation in group A than in group B (17.8% vs. 7.3%, P=0.031). The long-term follow-up revealed that the recurrence rate of tricuspid regurgitation in group B was significantly lower than that in group A (11.0% vs. 25.0%, P=0.029), and the ratio of cases developing into moderate to severe tricuspid regurgitation in group A was significantly higher than that in group B (28.9% vs. 9.9%, P=0.007). The comparison between the two intra-group time segments showed that the development of tricuspid regurgitation in group A was significantly increased (28.9% vs. 17.8%, P=0.022), but in group B it was relatively stable (9.9% vs. 7.3%, P=0.52).Conclusions:Artificial ring annuloplasty is associated with significantly less tricuspid regurgitation than simple suture annuloplasty.

ABSTRACT

Objective To validate the analysis capability of RapidHITTM 200 system for four kinds of routine forensic samples and the recyclable capability of template, template DNA and PCR products in the process of twice duplicate detection. Methods The buccal swabs underwent the test twice by RapidHITTM 200 system, and the template DNA and PCR products that arose in the system were also tested for two times. After four kinds of routine forensic samples were detected by RapidHITTM 200 system, the follow-up tests of the template, template DNA and PCR products that arose in the system were performed. Re-sults The STR loci could be detected in the buccal swabs by the system for the first time. However, part of the STR loci lost during the second test. And the peak value obtained in the second test was significantly reduced than the one in the first time. The average STR loci detection rates of the template DNA and PCR products were both less than 50% in the second test, which were significantly reduced than that in the first test. In addition, the analysis capability of the system for the tissues and buccal swabs was better than that for the blood and cigarette butts. Compared with the first test, the STR loci detection rate of the tested items, template DNA and PCR products decreased with the numbers of tests. Conclusion RapidHITTM 200 system is more effective in retesting buccal swabs than other samples, whereas the items, DNA template, PCR products obtained in the first and second time cannot be directly used for the further application and study of forensic medicine.

ABSTRACT

The safety of occupational exposure to inhaled anesthetics remains a concern among the medical staff in hospitals. Few reports are seen about the impact of inhaled anesthetics on the reproductive system, particularly that of males. Several clinical and basic studies on isoflurane and others suggest that inhaled anesthetics affect the reproductive system of rodents by decreasing the sperm count, inducing sperm morphological abnormality, reducing sperm motility, and changing the levels of reproductive hormones, the underlying mechanisms of which are mainly associated with the alteration of the hypothalamic-pituitary-gonadal axis and DNA damage and apoptosis of reproductive cells. This article reviews the main impacts of inhaled anesthetics on the male reproductive system and the possible mechanisms.

ABSTRACT

Objective To investigate the therapeutic effect of modified S-P approach without disconnecting the rectus femoris in patients with Pipkin typeⅠandⅡfractures. Methods The clinical data of 58 patients with Pipkin type Ⅰ and Ⅱfractures were retrospectively analyzed. Among the patients, 29 patients were treated with conventional S-P approach (conventional group), and 29 patients were treated with modified S-P approach (modified group). The incision length, operation time, bleeding, visual analogue score (VAS), postoperative complications and hip joint function at the final follow-up were compared between 2 groups. Results The patients of 2 groups had not incision infection, and showed primary. X-ray of 3 months after surgery showed fracture healing. There was no statistical difference in the time of follow-up between conventional group and modified group:(16.1 ± 5.2) months vs. (15.8 ± 5.6) months, P>0.05. The incision length, bleeding, VAS 3 d and 4 weeks after surgery in modified group were significantly lower than that in conventional group:(8.1 ± 0.8) cm vs. (12.3 ± 1.2) cm, (144.3 ± 16.5) ml vs. (172.4 ± 21.6) ml, (4.5 ± 1.1) scores vs. (5.9 ± 1.5) scores and (1.6 ± 0.7) scores vs. (2.4 ± 0.8) scores, and there were statistical differences (P0.05). Conclusions The modified S-P approach without disconnecting the rectus femoris is a better method in patients with Pipkin type ⅠandⅡ fractures, and it has the advantages of revealing more clearly, minimal invasion, lower bleeding and slight postoperative pain.

We investigated the formation mechanism and immediate constituents of nanotubes between adjacent bacteria,pre venting rapid increase of drug-resistant bacteria provide potential targets.We used scanning electron microscopy(SEM) to observe formation of nanotubes;glutamic was determined by surface desorption atmospheric pressure chemical ionization mass spectrometry(SDAPCI-MS)and peptidoglycan was determined by enzyme linked immunosorbent assay(ELISA) in the forma tion of nanotubes before and after.The results showed that Staphylococcus aureus and Escherichia coli consumed more glutamic after formation of nanotubes;at the same time,the concentration of peptidoglycan in nanotubes formation of S.aureus and E.coli increased significantly.This study illuminated the glutamic and peptidoglycanin role mechanism of nanotubes form.We found that peptidoglycan is constituents of nanotubes and glutamic is the main energy source for the formation of nanotubes.
