RESUMO
@#Objective To examined gene mutations in thymic carcinoma (TC) patients and to explore prognostic correlates and potential targets for therapy. Methods We retrospectively included TC patients in Sichuan Cancer Hospital between January 2015 and Febuary 2021.Whole-exome sequencing was performed on tumor tissues from TC patients and their control peripheral blood samples, and the raw data were subjected to bioinformatics analysis and statistical analysis. Results We finally included 24 TC patients with 16 males and 8 females at a median age of 55 (42-74) years. The highest frequency of single nucleotide mutations in this cohort were in the TTN gene (42%), HSPG2 (29%), and OBSCN (29%). Higher frequency of copy number variations occurred in ZNF276 gene (54%, loss), BEND3 (50%, loss), DHODH (50%, loss), and VAC14 (50%, loss). Microsatellite instability (MSI) phenotype was found in 25% of the patients, and the mean tumor mutation burden (TMB) was 9.86. Conclusion This study is the first comprehensive analysis of the mutation profile of thymic carcinoma in China to date. The mutation frequencies of TTN, OBSCN, and ZNF276 genes were high. The biomarker analysis suggests that patients may benefit from immunotherapy and have a long effective survival.
RESUMO
Objective: To investigate the relationship between nutritional risk status and clinical outcome in children with tuberculous meningitis (TBM). Methods: The clinical data (basic information, clinical symptoms and laboratory test results) of 112 patients with TBM, who were admitted to Department of Pediatric Infectious Diseases of West China Second Hospital of Sichuan University,from January 2013 to December 2020 were retrospectively analyzed. The patients were divided into the nutritional risk group and the non-nutritional risk group according to the assessment of the nutritional risk by the STRONGkids Scale. The variables of basic information, clinical symptoms and laboratory test measurements etc. were compared between the two groups by using Student t test, Rank sum test or Chi-square test. Multivariate Logistic regression analysis were used to analyze nutritional risk factors. Results: Among 112 patient with TBM, 55 were males and 57 females. There were 62 cases in the nutritional risk group and 50 cases in the non-nutritional risk group. The proportion of cases with nutritional risk was 55.4% (62/112). Patients in the nutritional risk who lived in rural areas, had symptoms of brain nerve damage, convulsions, emaciation and anorexia, with a diagnosis time of ≥21 days, and the level of cerebrospinal fluid (CSF) protein were all higher than those in the non-nutritional risk group ((50 cases (80.6%) vs. 32 cases (64.0%), 20 cases (32.3%) vs.8 cases (16.0%), 33 cases (53.2%) vs. 15 cases (30.0%), 30 cases (48.4%) vs. 2 cases (4.0%), 59 cases (95.2%) vs. 1 case (2.0%),41 cases (66.1%) vs.18 cases (36.0%), 1 406 (1 079, 2 068) vs. 929 (683, 1 208) mg/L, χ2=3.91, 3.90, 6.10, 26.72, 98.58, 10.08, Z=4.35, all P<0.05). The levels of serum albumin,hemoglobin,lymphocyte count, white blood cell count, and CSF glucose were significantly lower in patients with nutritional risk ((36±5) vs. (41±4) g/L, (110±17) vs. (122±14) g/L, 1.4 (1.0, 2.0)vs. 2.3 (1.6, 3.8)×109/L, 7.8 (6.3, 10.0)×109 vs. 10.0 (8.3, 12.8)×109/L, 1.0 (0.8, 1.6) vs. 2.1 (1.3, 2.5) mmol/L, t=-6.15, -4.22, Z=-4.86, -3.92, -4.16, all P<0.05).Increased levels of serum albumin (OR=0.812, 95%CI:0.705-0.935, P=0.004) and lymphocyte count (OR=0.609, 95%CI:0.383-0.970, P=0.037) may reduce the nutritional risk of children with TBM; while convulsions (OR=3.853, 95%CI:1.116-13.308, P=0.033) and increased level of CSF protein (OR=1.001,95%CI:1.000-1.002, P=0.015) may increase the nutritional risk of children with TBM. Similarly, the rate of complications and drug-induced liver injury was higher in the nutritional risk group (47 cases (75.8%) vs. 15 cases(30.0%), 31 cases (50.0%) vs.8 cases (16.0%), χ2=23.50, 14.10, all P<0.05). Moreover, the length of hospital stay was also longer in the nutritional risk group ((27±13) vs. (18±7) d, t=4.38, P<0.05). Conclusions: Children with TBM have a high incidence of nutritional risk. Convulsive, the level of serum albumin, the level of lymphocyte count and CSF protein may affect the nutritional risk of children with TBM. The nutritional risk group has a high incidence of complications and heavy economic burden.It is necessary to carry out nutritional screening and nutritional support for children with TBM as early as possible.

Autophagy is an evolutionarily highly conservative lysosomal degradative process and closely associates with pathogenesis, process, treatment, drug resistance and relapse of acute lymphoblastic leukemia (ALL). Whether the autophagy displays resistance to chemotherapy or a tumor suppressor in ALL, it mainly depends on the context of autophagy in the cells. Understanding the different role of autophagy in different conditions for ALL, determing the autophagy signaling pathways and targeting combination with autophagy revulsants or inhibitors were significant for the therapy of ALL, particularly for the treatment of refractory/relapsed ALL patients. This review summarizes the role of autophagy in pathogenesis, developmant, drug resistance and treatment of ALL, providing some theoretical guidance of new drugs targeting autophagy for ALL therapy.

<p><b>OBJECTIVE</b>To investigate the effect of magnolol on proliferation and apoptosis of HL-60 cells and its mechanism.</p><p><b>METHODS</b>MTT assay was used to measure the proliferation of HL-60 cells after treatment with different concentration of magnolol (5, 10, 20, 40, 80 and 160 µg/ml). The morphological changes of HL-60 cells were examined by light microscopy, and DAPI staining was performed to observe the nuclear morphology of HL-60 cells. The early cell apoptosis was detected by flow cytometry with Annexin V-FITC/PI double-staining. RT-PCR was carried out to examine the mRNA expression of BAX and BCL-2. Western blot was performed to detect the protein expression of caspase family.</p><p><b>RESULTS</b>The magnolol inhibited HL-60 cell proliferation, and the inhibitory rate of cell proliferation increased significantly in a dose- and time- dependent manner (P < 0.05). HL-60 cells became small, even apoptotic bodies appeared after treatment with magnolol. In addition, nuclear condensation or fragmentation could be observed, which is the typical morphological features of apoptosis. When HL-60 cells were treated with 40 µg/ml of magnolol for 24 h, the ratio of early apoptotic cells reached to (11.7 ± 2.4) %, which was significant different from control (1.4 ± 1.1) % (P < 0.05). RT-PCR results showed that treatment of HL-60 cells with magnolol up-regulated the expression of BAX, whereas down-regulated the expression of BCL-2. Western blot results showed that the cleavages of caspase-3, -8 and -9 were significantly enhanced by magnolol.</p><p><b>CONCLUSION</b>The magnolol can significantly inhibit the proliferation of HL-60 cells and induce the apoptosis of HL-60 cells, which may occur through up-regulation of BAX, down-regulation of BCL-2 and the activation of caspases.</p>

<p><b>OBJECTIVE</b>To study the relationship between nasal carriage and Staphylococcus aureus (S. aureus) infection in hospitalized children.</p><p><b>METHODS</b>Fifty-six hospitalized children infected with S. aureus were recruited in this study. Nasal swabs were collected and cultured, and the nasal carriage rate of S. aureus was examined. PVL virulence gene and mecA resistance gene were both detected in clinical strains and nasal carriage strains by PCR.</p><p><b>RESULTS</b>Twenty-two (39%) of the 56 children had nasal carriage of S. aureus, and most of them (18 cases) were younger than one year. Among these 22 children, 11 (50%) had previous hospitalization over the past year. In the infected strains, the rate of methicillin-resistant S. aureus (MRSA) was 29% (16/56), while it was 32% (7/22) in carriage strains. The mecA positive results in clinical strains were consistent with the results in nasal carriage strains. Among 5 PVL-positive nasal carriage strains, 4 (90%) could be matched with their clinical strains, all of which were MRSA.</p><p><b>CONCLUSIONS</b>Nasal carriage is a potential risk factor for S. aureus infection. Nosocomial transmission may lead to nasal carriage, which can cause S. aureus infection. The isolation rate of MRSA is high in hospitalized children infected with S. aureus, which implies that more attention is needed for this situation. The isolates from noses may be clonally identical to the isolates from clinical secretions, and the homology between them needs to be confirmed by multi-locus sequence typing.</p>

RESUMO
<p><b>OBJECTIVE</b>To study the factors influencing short-term prognosis of tuberculous meningitis (TBM) in children.</p><p><b>METHODS</b>The clinical data of 137 hospitalized children with TBM between January 2007 and February 2011 were retrospectively reviewed. A total of 30 potential factors influencing short-term prognosis of TBM were evaluated by univariate analysis and multivariate logistic regression analysis.</p><p><b>RESULTS</b>Clinical staging showed that of the 137 children 21 cases (15.3%) were in the early stage, 67 cases (48.9%) in the medium stage and 49 cases (35.8%) in the late stage of TBM. The univariate analysis revealed 8 factors associated with a poor short-term prognosis: clinical stage of TBM (late), coma, positive Babinski signs, cranial nerve involvements, paralysis, seizures, obvious abnormalities in brain computed tomography (CT) or magnetic resonance imaging (MRI) and elevated protein concentrations in cerebrospinal fluid (CSF). Factors associated with a favourable short-term prognosis for TBM included glucocorticoid steroids therapy, positive reaction of PPD skin test and an increased length of stay in hospital. Multivariate logistic analysis revealed two independent risk factors for a poor short-term prognosis: clinical stage of TBM (late) (OR: 11.168, 95%CI: 3.521-35.426) and positive signs of meningeal irritation (OR: 4.275, 95%CI: 1.043-17.521). An increased length of stay in hospital was shown as a favorable factor (OR: 0.893, 95%CI: 0.825-0.968).</p><p><b>CONCLUSIONS</b>Late-stage TBM and positive signs of meningeal irritation suggest a poor prognosis, while an appropriately longer length of stay in hospital may contribute to a favorable short-term prognosis for children with TBM.</p>

<p><b>BACKGROUND</b>Complete tumour resection is important for improving the prognosis of brain tumour patients. However, extensive resection remains controversial because the tumour margin is difficult to be distinguished from surrounding brain tissue. It has been established that 5-amino-4-oxopentanoic acid (5-aminolevulinic acid, ALA) can be used as a photodynamic diagnostic marker and a photosensitizer for photodynamic therapy in surgical treatment of brain tumours. We investigated the efficacy of ALA photodynamically guided microsurgery and photodynamic therapy on VX(2) brain tumour implanted in a rabbit model.</p><p><b>METHODS</b>Eighty New Zealand rabbits implanted with VX(2) brain tumours were randomly assigned to five groups: control, conventional white light microsurgery, a photodynamic therapy group, a photodynamically guided microsurgery group and a group in which guided microsurgery was followed by photodynamic therapy. The VX(2) tumour was resected under a surgical microscope. The tumour resection was confirmed with histological analysis. All animals were examined with MRI for presence of any residual tumour tissue. The survival time of each rabbit was recorded.</p><p><b>RESULTS</b>All treatment groups showed a significantly extended survival time compared with the control group. Photodynamically guided microsurgery combined with photodynamic therapy significantly prolonged survival time, compared with guided microsurgery alone. MRI and the autopsy results confirmed removal of most of the tumours.</p><p><b>CONCLUSIONS</b>Our results suggest that photodynamically guided surgery and photodynamic therapy significantly reduce or delay local recurrence, increase the effectiveness of radical resection and prolong the survival time of tumour bearing rabbits. Their combination has the potential to be used as a rapid and highly effective treatment of metastatic brain tumours.</p>

BACKGROUND: There are many drawbacks with hormone replacement therapy for menopausal syndrome. The blood levels of 5-HT and norepinephrine are lower. Fluoxetine hydrochlorde(ProzacR) is a selective serotonin reuptake inhibitor which is widely used in treating anxiety and depression,OBJECTIVE: To evaluate the effect of combined antidepressant and estrogen therapy compared to estrogen alone in the treatment of perimenopausal syndrome in this prospective open study.DESIGN: Randomized comparative study.SETTING: Department of Obstetrics and Gynecology of the First Affiliated Hospital of Chongqing Medical University PARTICIPANTS: From November 2003 to December 2004, 60 female patients with diagnosed menopausal syndrome of 3-12 month duration, aged (46±3) years, from Department of Obstetrics and Gynecology of the First Affiliated Hospital of Chongqing Medical University were enrolled into the study after giving their informed consents. The patients were randomly divided into two equal groups with Group 1 (n=30) receiving a combination of antidepressant + estrogen and Group 2 (n=30) receiving estrogen only.METHODS: Patients in Grgup 1 received fluoxetine hydrochloride (ProzacR) 20 mg orally every morning plus oral estradiol 1 mg once every two weeks for 2 months. Patients in Group 2 received only oral estradiol 1 mg once every two weeks for two months. Patients were not taking any other drug during the treatment period. At the end of two month treatment all patients were evaluated with the following 3 assessment tools: ①female menopausal symptom evaluation with the following 4 categories: Complete symptom relief, markedly improved, improved and no effect. Overall efficacy was defined as 50% symptom improvement. ② Hamilton Depression Scale which reflects energy level and psychosomatic factor of sleep and anxiety. ③Menopause index: Which are description of clinical evaluation and adverse effects; this would help to assess the safety of using both drugs in treating the menopausal syndrome.MAIN OUTCOME MEASURES: female menopausal symptom assessment, hamilton depression scale, and menopause index.RESULTS: ① In female menopausal symptom assessment group 1 showed better results in the complete relief and markedly improved scores. ②Hamilton Depression Scale group 1 also showed better scores than Group2(In Groupl, the scores at week 1 to 8 were 25,18,15,10,8,5,5,4 respectively ,in Group 2, the scores at week 1 to 8 were 25,17,15,14,13,12,13,13 respectively). ③ Group 3 showed a significant better score in the menopausal index with improvement in sleep disorder, anxiety and depression than Group 2 (In Group 1 the scores at week 1-8 were 32,22.5,15,15,14,15,15,14 respectively,In group 2, the scores at week 1 to 8were 33,21,16,14,13,12,13,13 respectively) ,there was no significant difference of incidence of adverse events as compared with Group 3 .CONCLUSION: Combined therapy of fluoxetire hydrochlarde(PROZAC)plus estrogen showed better efficacy in the treatment of menopausal syndrome than estrogen alone.
