ABSTRACT

BACKGROUND AND OBJECTIVE: To investigate the oncologic outcomes of patients with esophageal squamous cell carcinoma (ESCC) who have achieved a pathologic complete response (pCR) of the primary tumor (ypT0) after neoadjuvant chemoradiotherapy (NCRT). METHODS: Patients with thoracic ESCC who underwent scheduled NCRT followed by surgery at our hospital between January 2010 and December 2022 were retrospectively analyzed. Only patients with ypT0 disease were enrolled in this study. RESULTS: A total of 118 patients were ultimately enrolled in this study. Ninety-two patients achieved pCR in the primary tumor and lymph nodes (ypT0N0), while 26 patients had residual metastatic disease in 52 lymph nodes (ypT0N+). Forty-five of the 52 lymph nodes with residual tumors were abdominal lymph nodes. Positive lymph nodes were more often observed in patients with tumors located in the lower third of the esophagus. The 1-, 3-, and 5-year overall survival (OS) rates for the entire study group were 96.5%, 79.5%, and 77.1%, and the 1-, 3-, and 5-year disease-free survival (DFS) rates were 90.5%, 76.8%, and 69.0%, respectively. According to multivariate analyses, pN classification was an independent predictor of both OS and DFS (P < 0.05), while sex and cT classification were also found to be independent prognostic factors for DFS (P < 0.05). CONCLUSIONS: Residual nodal metastatic disease in patients with ypT0 ESCC after NCRT was more often found in the abdominal lymph nodes. pN classification was an independent predictor of both OS and DFS for ypT0 ESCC patients after NCRT.

ABSTRACT

Combustion of domestic solid fuels is a significant source of polycyclic aromatic hydrocarbons (PAHs). Some oxygenated PAHs (o-PAHs) and PAHs with molecular weight of 302 (MW302 PAHs) are more toxic than the traditional 16 priority PAHs, whereas their emissions were much less elucidated. This study characterized the size-dependent emissions of parent PAHs (p-PAHs), o-PAHs, and MW302 PAHs from various combustion sources. The estimated emission factors (eEFs) from biomass burning sources were highest for most of the PAHs (391-8928 µg/kg), much higher than that of anthracite coal combustion (43.0-145 µg/kg), both which were operated in an indoor stove. Cigarette smoking had a high eEF of o-PAHs (240 ng/g). MW302 PAHs were not found in the emissions of smoking, cooking, and vehicular exhausts. Particle-size distributions of PAHs were compound- and source-dependent, and the tendency to associate with smaller particles was observed especially in biomass burning and cigarette smoking sources. Furthermore, the inter-source differences in PAH eEFs were associated with their dominance in fine particles. PAH composition profiles also varied with the particle size, showing increasing contributions of large-molecule PAHs with decreasing sizes in most cases. The size distributions of p-PAHs are much more significantly dependent on their n-octanol/air partition coefficients and vapor pressures than those of o-PAHs, suggesting differences in mechanisms governing their distributions. Several molecular diagnostic ratios (MDRs), including two based on MW302 PAHs, specific to these combustion scenarios were identified. However, the MDRs within some sources are also strongly size-dependent, providing a new explanation for the uncertainty in their application for source identification of PAHs. This work also highlights the necessity for understanding the size-resolved atmospheric behaviors and fate of PAHs after their emission.

ABSTRACT

BACKGROUND: Esophageal adenosquamous carcinoma (EASC) is a rare disease. The biological behavior and treatment of this malignancy are not well studied. METHODS: Data from 56 patients with EASC who underwent esophagectomy were retrospectively analyzed and compared with 5028 patients with esophageal squamous cell carcinoma (ESCC). The impact of clinicopathological factors on the survival of patients with EASC was analyzed. The survival differences between patients with EASC and ESCC were also compared. RESULTS: There were 43 males and 13 females with a mean age of 59.7 ± 1.3 years (range, 39-79 years). Only 1 of the 43 patients who received preoperative esophagoscopic biopsy was diagnosed with EASC. The median survival time for patients with EASC was 32.0 months, and the 1-, 3-, and 5-year overall survival rates were 78.3%, 46.1%, and 29.6%, respectively. Resection margin, pN category, and adjuvant chemotherapy were found to be independent predictors. After 1:1 propensity score matching, the 5-year overall survival rate of 29.6% for patients with EASC was similar to that of 42.5% for patients with ESCC (P = 0.179). CONCLUSIONS: EASC is a rare disease and is easily misdiagnosed by esophagoscopic biopsy. The prognosis of EASC was similar to that of ESCC. Postoperative adjuvant chemotherapy may improve the survival of patients with EASC after esophagectomy.

ABSTRACT

BACKGROUND: To document the evolution of the Peripherally Inserted Central Catheter service at Princess Margaret Hospital, now Perth Children's Hospital. METHODS: Between January 2012 and June 2013 patients referred to Anaesthesia for a Peripherally Inserted Central Catheter were prospectively followed up. A repeat audit was conducted between January 2015 and June 2016, following the introduction of a number of measures aimed at improving the service. RESULTS: Audit 1: A total of 200 Peripherally Inserted Central Catheter insertions were attempted in 138 patients. Successful placement occurred in 86% of cases (172/200). The median age of patients was 7.71 years (range 0-20). The percentage of Peripherally Inserted Central Catheters remaining in situ for the predicted duration was 49/172 (28.5%). Complications were documented in 78/172 (45.4%) of cases. Audit 2: A total of 310 Peripherally Inserted Central Catheter placements were attempted in 244 patients. Successful insertion rate was 95.5% (296/ 310). The median age of patients was 5.3 years (range 0.0-18.72). The percentage remaining in situ for the predicted duration was 145/296 (49%). Complications were documented in 67/296 (22.6%) of cases. CONCLUSION: The evolution of the Peripherally Inserted Central Catheter service at our free standing Tertiary Paediatric Hospital is well documented following these 2 audits. The introduction of a dedicated Anaesthesia led Peripherally Inserted Central Catheter service at our centre has resulted in improved insertion success rates and a reduction in complications.

ABSTRACT

A pink-pigmented, Gram-stain-negative, rod-shaped, strictly aerobic bacterial strain MIMtkB3T, was isolated from moss crusts in Hunshandake desert of China. Cells grew at 15-45 °C (optimum of 28 °C), at pH of 6.0-8.5 (optimum of 7.0) and with 0-1.0 % (w/v) NaCl (optimum of 0 %). The strain could biosynthesize the green-coloured pigment bacteriochlorophyll a (BChl a). The respiratory quinone was ubiquinone Q-10, while C18 : 1 ω7c and C18 : 1 2OH were the major fatty acids. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified aminophospholipid, one unidentified phospholipid, three unidentified glycolipid and one unidentified lipid were the major polar lipids. Strain MIMtkB3T was most closely related to Oleisolibacter albus NAU-10T, Niveispirillum fermenti CC-LY736T, and Rhodocista centenaria SW of the family Rhodospirillaceae with 16S rRNA gene similarities of 93.09, 92.02 and 91.73%, respectively. The genomic DNA G+C content calculated on complete genome sequencing was 69.3 mol%. The average nucleotide identity between strain MIMtkB3T and its closely related type strains in Rhodospirillaceae was below 77.96 % and digital DNA-DNA hybridization lower than 24.70 %. Full light utilization pathway of aerobic anoxygenic phototrophic bacteria was identified in the genome. Based on phenotypic, chemotaxonomic and phylogenetic characteristics, strain MIMtkB3T represents a novel genus of the family Rhodospirillaceae, for which the name Aerophototrophica crusticola gen. nov., sp. nov. is proposed. The type strain is MIMtkB3T (=KCTC 42633T=MCCC 1K00570T).

ABSTRACT

AIM: Bacteraemia episodes were assessed to calculate a hospital-wide central line-associated blood stream infection (CLABSI) rate per 1000 catheter-days. Secondary objectives were to describe risk factors, microbiology and outcomes of children with CLABSI. METHODS: A retrospective study was conducted at an Australian tertiary paediatric hospital in children <18 years who had blood culture sampling during the 2-year period, 2014-2015. All blood culture results were extracted from the hospital's laboratory information system. National Healthcare Safety Network Centres for Disease Control and Prevention definitions for bacteraemia classification were used. Central venous access device (CVAD) insertion and removal dates were obtained from a surgical electronic database and anaesthetic records and then manually validated. RESULTS: Of 11 774 processed blood culture bottles, 207 episodes of blood stream infection were observed. Eighty-five (41%) episodes were community-acquired bacteraemia (CA-B) and 122 (59%) health care-associated bacteraemia (HA-B), of which 73 (35%) were CLABSI. The hospital-wide CLABSI rate was 0.62 per 1000 catheter-days (95% confidence interval: 0.49-0.77). Conditions associated with CLABSI were malignancy (n = 45, 62%) and gastrointestinal failure (n = 6, 8%). Thirty-three (45%) CLABSI episodes developed in an outpatient setting. CONCLUSIONS: HA-B has a significant impact on child health, exceeding the number of CA-B at our hospital. Children with CVADs are vulnerable in both the inpatient and outpatient settings. Collecting robust data for a hospital-wide CLABSI rate is important to understand the full spectrum of paediatric CLABSI. The value of validating data using both electronic and manual methods is demonstrated.

ABSTRACT

AIMS AND OBJECTIVES: To explore couples' perceptions of the effects of perinatal loss on their marital relationship, social support and grief 1 year postloss, and analyse what factors changed the severity of their grief. BACKGROUND: Perinatal losses are traumatic events in the lives of families and can have serious long-term consequences for the psychological health of parents and any subsequent children. DESIGN: A prospective follow-up study. METHODS: We recruited, at a teaching hospital in southern Taiwan, a convenience sample of 30 couples whose babies either miscarried or were stillborn. At 1 month (T1), 3 months (T2), 6 months (T3) and 1 year (T4) after the pregnancy loss, all participants completed four questionnaires. To analyse the changing status of their grief and its related factors, we used a generalised estimating equation (GEE) to account for correlations between repeated observations. RESULTS: Postbereavement grief levels fell over the four time-points. Mothers reported feeling more grief than did the fathers. Couples with a history of infertility, no religious beliefs or no living children before the loss felt more grief from a perinatal miscarriage or stillbirth. Furthermore, couples reported more grief if their marital satisfaction level was low, if their socioemotional support from husband's parents was low or if they had never participated in a ritual for their deceased baby. CONCLUSIONS: Six months postloss is the crucial period for bereaved parents after a perinatal loss. Being a mother, having no previous living children and low-level socioemotional support from the husband's parents are significant high-risk factors for a high level of grief 1 year after perinatal death. RELEVANCE TO CLINICAL PRACTICE: We recommend that health professionals increase their ability to identify the factors that psychologically affect postloss grief. Active postloss follow-up programmes should focus on these factors to offer specific support and counselling.

ABSTRACT

BACKGROUND: Perinatal losses are traumatic events for women and may have serious long-term consequences for the psychological health of women and subsequent pregnancies. Therefore, it is important to explore the psychological adaptation process of subsequent pregnancy after loss in order to understand the overall phenomenon of perinatal loss. PURPOSE: To explore the childbearing experiences of women who have experienced a prior stillbirth. METHODS: This qualitative descriptive study targeted a purposive sample of 15 women who had prior personal experiences with stillbirth. A total of 22 in-depth interviews were conducted in order to ensure data saturation. Women who had experienced stillbirth at one of two teaching hospitals in southern Taiwan were recruited. Data were analyzed using content analysis. RESULTS: Three themes were identified that captured the complex feelings of participants regarding their subsequent childbearing experiences: (1) looking forward to another pregnancy but afraid of being hurt again, (2) treading on thin ice, and (3) bearing another child helps heal the loss of the stillborn. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The empirical data gathered in the present study helps build a more complete understanding of the process of recovery that women undergo following a stillbirth experience. In addition, the results suggest that healthcare professionals should be aware of and accept the worries and reactions of women during their subsequent pregnancy in order to help these women achieve a positive subsequent childbearing experience.

ABSTRACT

A 12-week Wheelchair Tai Chi 10 Form (WTC10) intervention was conducted among elderly with disability to examine the effect of this WTC10 intervention on selected physical and mental health variables. Thirteen (age 87.23 ± 6.71) in the WTC10 intervention group and 15 (age 89.73 ± 6.31) in the control group completed the study. Independent t-tests and paired t-tests were employed to examine the differences between groups and within groups, respectively, at pretest and post-test. The WTC10 intervention group showed significant improvements in systolic and diastolic blood pressure, shoulder external rotation, left trunk rotation and total trunk rotation after the intervention. A 12-week WTC10 intervention had positive effects on blood pressure, range of motion at the shoulder and trunk, physical activity, and mental health among the elderly with disability. WTC10 is a feasible and safe exercise for the elderly with disability.

ABSTRACT

OBJECTIVE: To systematically examine the research literature on the effectiveness of constraint-induced movement therapy on improving arm function in children with cerebral palsy, and to assess the association between the study effect size and the characteristics of the patients and intervention protocol. DATA SOURCES: A systematic literature search was conducted in PubMed, PsycINFO, Cochrane, CINAHL, Web of Science, and TRIP Database up to May 2014. REVIEW METHODS: Studies employing randomized controlled trial design, children with cerebral palsy, comparing constraint-induced movement therapy with another intervention with a focus on arm function, and upper-extremity measures were included in this review. Methodological quality was evaluated using the Physiotherapy Evidence-based Database (PEDro) scale. RESULTS: The literature search resulted in 27 randomized controlled trial studies with good methodological quality that compared constraint-induced movement therapy with other intervention therapy. Overall, constraint-induced movement therapy provided a medium beneficial effect (d = 0.546; p < 0.001) when compared with conventional therapy. For the subgroup analyses, presence of a dose-equivalent comparison group, intervention location, and time of follow-up were significant factors. Studies examining constraint-induced movement therapy effect without a dose-equivalent comparison group showed a large effect in children with cerebral palsy, but studies with a dose-equivalent group only showed a small effect. Children who received home-based constraint-induced movement therapy had a better improvement in arm function than those who received constraint-induced movement therapy elsewhere. CONCLUSION: The research literature supports constraint-induced movement therapy as an effective intervention to improve arm function in children with cerebral palsy.

ABSTRACT

PURPOSE: To systematically examine the effect of virtual reality (VR) on upper extremity (UE) function in children with cerebral palsy (CP) and assess the association among VR effects and children's characteristics and an intervention protocol. METHOD: A systematic literature search was conducted in PubMed, CINAHL, Cochrane, and PsycINFO up to June 2013. Research studies involving children with CP that used VR as the intervention method and UE outcome measures were included. RESULTS: The search yielded 14 research articles, including 3 randomized controlled trials and 11 case series. Overall, VR provided a strong effect size (d = 1.00) when comparing pre- and postintervention. In subgroup analyses, younger children receiving home-based or laboratory-based VR and using an engineer-built VR system showed better improvement. CONCLUSIONS AND IMPLICATIONS: Virtual reality is a viable tool to improve UE function in children with CP. However, a more vigorous research design is needed to make a conclusive recommendation.

ABSTRACT

BACKGROUND: Protein Tyrosine Phosphatase Receptor-type O (PTPRO) has recently been in the spotlight as a tumor suppressor, whose encoding gene is frequently methylated in cancers. We examined the methylation status of the PTPRO gene promoter in breast cancer and evaluated the correlation between PTPRO promoter methylation and both clinicopathological parameters and prognosis of breast cancer patients. METHODS: Two hundred twenty-one formalin-fixed, paraffin-embedded (FFPE) tumor tissues, 20 FFPE normal adjacent tissues and 24 matched plasma samples, collected from primary breast cancer patients, were assessed for PTPRO gene promoter methylation using methylation-specific PCR. Associations of promoter methylation with clinicopathological parameters were evaluated. Kaplan-Meier survival analysis and Cox proportional hazards models were used to estimate the effect on survival. RESULTS: 175 samples gave identifiable PCR products, of which 130 cases (74.3%) had PTPRO gene promoter methylation. PTPRO methylation correlated with higher histological grade (P = 0.028), but not other clinical parameters. Multivariate analysis indicated that overall survival (OS) was significantly poorer in HER2-positive, but not ER-positive patients with methylated-PTPRO. Methylated-PTPRO was detectable in matched plasma samples and only observed in plasma from patients whose corresponding primary tumors were also methylated. CONCLUSIONS: PTPRO methylation is a common event in the primary breast cancer and can be reliably detected in peripheral blood samples. PTPRO methylation is associated with poor survival only in HER2-positive patients, suggesting use of PTPRO methylation as a prognostic factor for breast cancer and for optimizing individualized therapy for HER2-positive patients.

ABSTRACT

Clinical classification and age distribution in myasthenia gravis (MG) cases seem different between Oriental and Caucasian populations, but there have rarely been any clinical studies on MG patients from mainland China. The goal of the current study was to perform a comprehensive survey of myasthenia gravis in a hospital in China, establishing contemporary cohort data and clinical features. 1,108 unselected patients with MG attending the 309th Hospital of PLA, Beijing, China were studied during a 36-month period from July 2008 to June 2011. The sex ratio was 1:1 (F:M). 62.5 % of patients presented as adolescents and adults. Ocular MG cases accounted for 65.6 % childhood MG patients. A positive response was observed in 96.8 % of the patients for neostigmine tests, whereas a positive decremental response to low frequency repetitive nerve stimulation (RNS) was observed in 77.4 % of the patients. The highest stimulating positive rate was 65.3 % in stimulated facial nerve. Thymoma was significantly increased in those patients with severe MG, especially in the cohort involving the respiratory muscles (p < 0.001). The study revealed higher frequency of ocular and childhood MG compared to other studies in USA and European countries, which can be a result of optimum case ascertainment, increased disease duration, or application of complex diagnostic tests. The relative increase in the prevalence of ocular myasthenia can be attributed to the impact of an aging population.

ABSTRACT

PRIMARY OBJECTIVE: The mechanism underlying interleukin-6 (IL-6) prevention of N-methyl-D-aspartate (NMDA)-induced neuronal Ca(2+) overload was explored at the profile of Ca(2+) channel receptors, including NMDA, inositol 1,4,5-trisphosphate and ryanodine receptors (NMDAR, IP3R and RyR, respectively). METHODS: Cerebellar granule neurons from 8-day-old rats were exposed to IL-6 (40 or 120 ng ml(-1)) for 8 days and stimulated with NMDA (100 µM) for 15 or 30 minutes. RESULTS: NMDA evoked an acute and sustained enhancement of intracellular Ca(2+) fluorescence intensity in the entire 15-minute NMDA application period. IL-6 prevented the acute and sustained intracellular Ca(2+) elevation triggered by NMDA in a concentration-dependent manner. MK-801, an NMDAR antagonist, completely suppressed NMDA-evoked neuronal Ca(2+) overload in the absence or presence of IL-6. IP3R antagonist 2-APB lessened NMDA-evoked acute and sustained cytosolic Ca(2+) overload and IL-6 further reduced the acute 2-APB-dependent Ca(2+) component. Dissimilarly, after RyR antagonist DAN treatment, NMDA still induced an acute and sustained elevation of intracellular Ca(2+) levels, and the elevated Ca(2+) was significantly suppressed by IL-6. Moreover, IL-6 down-regulated NMDAR1 and IP3R1 but did not alter RyR2 expression. CONCLUSION: The present results suggest that IL-6 suppresses NMDA-induced neuronal Ca(2+) overload by inhibiting NMDAR and IP3R activities.

ABSTRACT

OBJECTIVE: To evaluate the efficacy and safety of tacrolimus in patients with generalized myasthenia gravis (MG). METHODS: A total of 69 cases admitted to our hospital were given 2-6 mg/day tacrolimus (FK506) for 12 months. The MG absolute and relative clinical scores were used to monitor the efficacy of tacrolimus. Clinical evaluation was conducted at month 1, 3, 6, and 12, while the serum concentration of FK506 was measured at one month after administration of tacrolimus for one month. RESULTS: The therapeutic response presenting as improved muscular strength showed within one month after administration of tacrolimus. The overall response rates (MG relative clinical score ≥ 25%) at month 1, 3, 6 were 81.2%, 87.6%, 92.2% respectively. It reached 93.8% by the final visit at month 12. MG score to evaluate disease severity decreased significantly as the subjects continued to take tacrolimus. Statistic analysis suggested that the serum concentration of FK506 was correlated with its therapeutic effect. Serum trough levels in remission and response groups [(7.1 ± 3.9) µg/L and (6.3 ± 3.8) µg/L, respectively] were significantly higher than that of no response group [(3.4 ± 1.3) µg/L]. The most common adverse effects included hyperglycemia (5 cases), myelosuppression (3 cases), and dizziness tinnitus (3 cases), majority of which were temporary and manageable. CONCLUSIONS: Our study has shown that tacrolimus significantly improved muscular strength of generalized MG patients. The treatment is well tolerated. The therapeutic effect of tacrolimus is observed within 1 month after initial use. Adverse events were manageable and not common.

ABSTRACT

Background: The aim of this study was to evaluate the impact of adjuvant chemotherapy in patients with radically resected esophageal squamous cell carcinoma (ESCC). Methods: Patients with esophageal cancer who underwent esophagectomy at our hospital from 2010 to 2019 were retrospectively analyzed. Only patients with radically resected ESCC who did not receive neoadjuvant therapy or adjuvant radiotherapy were enrolled in this study. Propensity score matching (1:1) was used to balance the baseline. Results: A total of 1,249 patients met the inclusion criteria and were enrolled in the study, and 263 patients received adjuvant chemotherapy. After matching, 260 pairs were analyzed. The 1-, 3-, and 5-year overall survival (OS) rates were 93.4%, 66.1% and 59.6%, respectively, for patients with adjuvant chemotherapy compared with 83.8%, 58.4% and 48.8%, respectively, for patients with surgery alone (P = 0.003). The 1-, 3-, and 5-year disease-free survival (DFS) rates were 82.3%, 58.8% and 51.3%, respectively, for patients with adjuvant chemotherapy compared with 68.0%, 48.3% and 40.8%, respectively, for patients with surgery alone (P = 0.002). In multivariate analyses, adjuvant chemotherapy was found to be an independent prognostic factor. In subgroup analyses, only the patients in certain subgroups were found to benefit from adjuvant chemotherapy, such as patients who underwent right thoracotomy, pT3 diseases, pN1-pN3 diseases, or pTNM stage III and IVA diseases. Conclusions: Postoperative adjuvant chemotherapy can improve the OS and DFS of ESCC patients after radical resection but may only work for patients in certain subgroups.

ABSTRACT

BACKGROUND AND PURPOSE: Cortical superficial siderosis (cSS) and cerebral microbleed (CMB) have distinct effects on intracerebral haemorrhage (ICH). We aim to investigate the combined effect of cSS and CMB on outcomes after ICH. METHODS: Based on a single-centre stroke registry database, patients with spontaneous ICH who had CT scan within 48 hours after ictus and MRI subsequently were identified. Eligible patients were divided into four groups (cSS-CMB-, cSS-CMB+, cSS+CMB-, cSS+CMB+) according to cSS and CMB on susceptibility-weighted image of MRI. Primary outcomes were haematoma volume on admission and unfavourable outcome defined as modified Rankin Scale scores ≥3 at 3 months. Secondary outcomes were all-cause death, recurrence of stroke and ICH during follow-up (median follow-up 2.0 years, IQR 1.0-3.0 years). RESULTS: A total of 673 patients were identified from 1044 patients with spontaneous ICH. 131 (19.5%) had cSS and 468 (69.5%) had CMB. Patients with cSS+CMB+ had the highest rate of poor outcome at 3 months, as well as all-cause death, recurrent stroke and ICH during follow-up. In cSS- patients, CMB was associated with smaller haematoma (ß -0.13; 95% CI -0.22 to -0.03; p=0.009), but it still increased risks of recurrent ICH (OR 4.6; 95% CI 1.3 to 15.6; p=0.015) and stroke (OR 2.0; 95% CI 1.0 to 4.0; p=0.049). These effects of CMB became unremarkable in the context of cSS+. CONCLUSIONS: Patients with different combinations of cSS and CMB have distinct patterns of short-term and long-term outcomes. Although CMB is related to restrained haematoma, it does not improve long-term outcomes. TRIAL REGISTRATION NUMBER: NCT04803292.

ABSTRACT

Background and Aims: Chronic hepatitis B (CHB) can cause liver fibrosis and lead to cirrhosis and cancer. As the effectiveness of antiviral therapy to reverse liver fibrosis is limited, We aimed to evaluate the effect of An-Luo-Hua-Xian pill (ALHX) on fibrosis regression in CHB patients treated with entecavir (ETV). Methods: Treatment-naïve patients with CHB were randomly treated with ETV alone or combined with ALHX (ETV+ALHX) between October 1, 2013 and December 31, 2020. Demographic, laboratory, and liver histology data before and after 78 weeks of treatment were collected. The Ishak fibrosis score (F) was used and fibrosis regression required a decrease in F of ≥1 after treatment. Results: A total of 780 patients were enrolled, and 394 with a second liver biopsy after treatment were included in the per-protocol population, 132 in ETV group and 262 in ETV+ALHX group. After 78 weeks of treatment, the fibrosis regression rate in the ETV+ALHX group was significantly higher than that of the ETV group at baseline F≥3 patients: 124/211 (58.8%) vs. 45/98 (45.9%), p=0.035. The percentage of patients with a decreased liver stiffness measurement (LSM) was higher in the ETV+ALHX group: 156/211 (73.9%) vs. 62/98 (63.%), p=0.056. Logistic regression analysis showed that ETV combined with ALHX was associated with fibrosis regression [odds ratio (OR)=1.94, p=0.018], and a family history of hepatocellular carcinoma was on the contrary. (OR=0.41, p=0.031). Conclusions: ETV combined with ALHX increased liver fibrosis regression in CHB patients.

ABSTRACT

OBJECTIVE: To review the clinical characteristics, diagnosis, treatment and prognosis of esophageal mucoepidermoid carcinoma (MEC). METHODS: Clinical data of 36 patients with pathologically confirmed esophageal MEC who received surgical treatment in Cancer Hospital of Shantou University Medical College from Jan 1991 to Jun 2010 were retrospectively analyzed. The survival analysis was performed using Kaplan-Meier method. RESULTS: Of the 4253 patients diagnosed as esophageal cancer during the same time in our center, only 36 had esophageal MEC, accounted for 0.8%. This group included 27 men and 9 women ranging in age from 40 to 78 years (median 58 years). Esophageal MEC showed similar clinical symptoms, radiological and endoscopic features to esophageal squamous cell carcinoma (ESCC). Of the 20 cases who received preoperatively endoscopic biopsy, 18 were misdiagnosed as ESCC and 2 were misdiagnosed as esophageal adenosquamous carcinoma. The mean follow-up duration of this series was 38.8 months (3-142 months). 22 patients died of the disease during the follow-up period, 12 were still alive and 2 were lost of follow-up. The median survival time (MST) of the 36 patients was 29.0 months, and the 1-, 2-, 3-, and 5-year overall survival rates (OS) were 80.6%, 57.1%, 34.4%, 25.8%, respectively. CONCLUSIONS: Esophageal MEC is a rare disease and prone to be misdiagnosed by endoscopic biopsy. Surgical resection is the primary treatment but the prognosis is poor.

ABSTRACT

OBJECTIVE: To investigate the immunoregulatory role of Th17 cell and the related cytokines in myasthenia gravis. METHODS: Totally 51 myasthenia gravis (MG) patients were divided into MG with thymomas (TM group) and the MG with normal thymus (NT group), as well as 22 healthy subjects as controls. Th17 cells from peripheral blood mononuclear cells were measured by flow cytometry. Th17 related cytokines were detected by ELISA and real-time quantitative-PCR. RESULTS: The quantity of Th17 cells in MG patients with thymomas (1.53 ± 0.59)% were significantly increased compared with that of healthy control (0.94% ± 0.32%, P < 0.05). There was no significant difference in the number of Th17 cells between healthy controls and NT group. The expression levels of IL-17 mRNA (23.7 ± 4.5) were up-regulated significantly versus those in healthy controls (13.4 ± 3.2, P < 0.01). The levels of mRNA expression of IL-1ß, IL-6 and IL-23 were up-regulated significantly in TM group. The mean concentration of IL-17 was up-regulated significantly in TM group (30.4 ± 7.3) ng/L versus healthy controls [(19.2 ± 4.9) ng/L, P < 0.05]. Serum levels of IL-23 and IL-1ß were always increased in TM group versus healthy controls. CONCLUSION: The elevated levels of IL-17 and other Th17 related cytokines in thymomas may aggravate the autoimmunity disorder.
