OBJECTIVE: To advocate Patient Assistant Program Projects (PAP Projects) decision-making, this study assesses the long-term cost-effectiveness of 1-year adjuvant trastuzumab therapy for women with human epidermal growth factor receptor 2 (HER2) positive early breast cancer. METHODS: A Markov model tracked yearly patients' transitions between five health states. The cycle length was 1 year and the sum was 45. From the perspective of the China health insurance system, the direct medical cost was estimated based on a survey of clinical expert panels. A discounting rate of 3% was used to discount direct medical cost and health outcomes. Utility and transition probabilities were retrieved from the HERA trial and literature. To estimate the direct medical cost, a survey of clinical expert panels was conducted. The cost of trastuzumab and HER2 test based on Roche. The key factor of the model was realized by one-way sensitivity analysis. The result of a probability sensitivity analysis conducted by Monte Carlo simulation was expressed as an incremental cost-effectiveness scatter plot. RESULTS: Without PAP Projects in Guangzhou, the adjuvant trastuzumab treatment prolonged 1.79 QALYs when the cost increased ¥53 301 and the Incremental cost-effectiveness ratio (CER) was ¥29 731/QALY, which is cost-effective based on Guangzhou's per capita GDP in 2015. With PAP Projects, the adjuvant trastuzumab treatment was totally cost-effectiveness. The sensitivity analysis demonstrated that the model was moderate. CONCLUSION: One year adjuvant trastuzumab treatment is a cost-effective therapy for patients with HER-2 positive breast cancer. With PAP Projects in Guangzhou, the adjuvant trastuzumab treatment is projected to be associated with improved QALYs and reduces direct medical costs, compared with the standard chemotherapy, represents a dominant treatment option among patients with HER2-Positive Early Breast Cancer. PAP Projects in Guangzhou should be persisted and spread in China.

AIM:To observe the changes of macular morphology and microcirculation in myopic maculopathy(MM), and investigate theirs correlation and effects on vision.METHODS: Case-control study. A total of 165 patients(189 eyes)with high myopia and 154 healthy volunteers(154 eyes)from October 2016 to December 2018 were selected. According to the classification of Meta-analysis for pathologic myopia(META-PM), participants were divided into M0 group(category 0, 41 eyes), M1 group(category 1, 53 eyes), M2 group(category 2 and 3, 52 eyes), and myopic choroidal neovascularization(mCNV)group(43 eyes). All participants underwent optical coherence tomography angiography(OCTA)examination. Morphological and microcirculation parameters of retina at different layers were compared between groups. Pearson correlation was used to assess the correlation between morphological and microcirculation parameters. Correlations between vision and other parameters were analyzed using multiple linear regression analysis.RESULTS:Foveal full retinal thickness(FRT)and outer retinal thickness(ORT)were all lower in M0, M1 and M2 groups than those of control group(all P<0.01). Foveal superficial capillary plexus vessel density(SVD)and deep capillary plexus vessel density(DVD)were all lower in M2 and mCNV groups than those of the control group(all P<0.01). Parafoveal FRT and ORT were all lower in M0, M1, M2 and mCNV groups than those of the control group(all P<0.01). Parafoveal inner retinal thickness(IRT), SVD and DVD were all lower in M2 and mCNV groups than those of the control group(all P<0.01). Subfoveal choroidal thickness(SFCT)and choroid capillaries vessel density(CVD)were all lower in M0, M1, M2 and mCNV groups than those of the control group(all P<0.01). Foveal vessel density of retina and choroid were positively correlated with its thickness in patients with MM without CNV(all P<0.05). Multivariate analysis showed that axial length(AL), diffuse or patchy chorioretinal atrophy were influencing foctors of best corrected visual acuity(BCVA; all P<0.01).CONCLUSION:Retinal morphological changes precede microcirculation changes in MM. Most of all, ORT changes precede IRT changes. Foveal vessel density of retina and choroid were positively correlated with its thickness. The main influencing factors of BCVA were AL and types of MM.

The level of viral DNA in patients with occult hepatitis B virus infection (OBI) is very low, and it is difficult to detect the conventional serum marker-HBsAg. OBI brought challenges to the clinical diagnosis and treatment and blood transfusion safety. The mechanism involved in OBI and the clinical implication are getting more and more attention. OBI has a complex mechanism that may involve host factors, the virus itself, and other viral or nonviral factors. OBI has the risk of HBV transmission. HBV can be reactivated and the liver disease can be aggravated in patients with OBI.

Objective:To investigate the changed functional connectivity (FC) of the visual network in patients with migraine without aura (MwoA).Methods:Clinical data of thirty-three patients with MwoA(MwoA group) who visited neurology department from July 2019 to July 2020 were collected, and twenty-two healthy volunteers were recruited as healthy controls (HCs group). All subjects underwent resting-state functional magnetic resonance imaging scans, and the RESTplus software package was used to analyze the resting state function data.The visual network was extracted based on independent component analysis to compare the differences in visual cortex.Subsequently, seed-base FC analysis was used to investigate the changed FC between the visual network and rest of whole brain.Results:Compared with the HCs group, the FC of left fusiform gyrus, right lingual gyrus and right superior occipital gyrus (SOG) within the visual network in MwoA group were significantly increased.MowA group showed increased FC between the left fusiform gyrus and the right superior frontal gyrus (SFG) and left anterior cingulum cortex (ACC), between the right lingual gyrus and left thalamus, left middle frontal gyrus (MFG) and right SFG, and between the right SOG and the SFG, as well as the decreased FC between the left fusiform gyrus and the left inferior occipital gyrus (IOG). Moreover, the changed FC between the left fusiform gyrus and left ACC was positively correlated with disease duration ( r=0.365, P=0.047), and the changed FC between the left fusiform with right SFG was negatively correlated with headache severity ( r=-0.424, P=0.020). Conclusion:The FC of inter- and intra-visual network in MwoA patients is changed, with parts of brain regions are associated with some neural circuits.Additionally, the compensatory period translates to the worse period along with disease progression in MwoA.

OBJECTIVE: To investigate the influence of influence of combination with 1q21 amplification or-no in patients with newly diagnosed MM on the clinical effecacy of bortezomib-based induction chemotherapy and long-term prognosis of patients. METHODS: 148 patients with newly diagnosed MM treated from January 2010 to May 2018 were selected and divided into 2 groups: group A (70 patients) without 1q21 amplification and group B (78 patients) with 1q21 amplification; and the survival benefit and influence on clinical efficacy of bortezomib were compared between 2 groups, and the factors influencing clinical prognosis in the patients with newly diagnosed MM were analyzed. RESULTS: The median PFS and OS of patients in B group were significantly shorter than those in group A (P＜0.05). There was no significant difference in the median OS and PFS between patients with 1q21 amplification copies number =3 and ＞3 (P＞0.05). Multivariate Cox model analysis indicated that the adverse factors for OS were ISS staging, Hb levels, β2 microglobulin levels and 1q21 amplification respectively, and the adverse factors for PFS were Hb levels and 1q21 amplification respectively in patients with newly diagnosed MM (P＜0.05). The very good partial remission rate of newly diagnosed MM patients with 1q21 amplification and bortezomib-based induction chemotherapy were significantly higher than that in the patients without bortezomib-based induction chemotherapy (P＜0.05). The median PFS time of newly diagnosed MM patients with 1q21 amplification and auto-HSCT after bortezomib-based induction chemotherapy was significantly longer than that of patients without auto-HSCT (P＜0.05). CONCLUSION 1q21 amplification should be the independent risk factor for poor prognosis of patients with newly treated MM. The application of bortezomib-containing induction chemotherapy in patients with 1q21 amplification can efficiently improve the remission rate, while auto-HSCT consolidation therapy may prolong patients' PFS.

OBJECTIVETo investigate the influence of different crown cutting mode on operation time and post-operation trauma in extracting the mandible third molar by dental drilling system.

METHODSAccording to different impaction types, the patients were divided into vertical impaction, horizontal impaction, and mesioangular impaction groups. The operation time, mouth opening, swelling, and pain degrees were recorded during traditional extraction, crown "T"-shaped cutting, crown three section cutting, and crown-root cutting in the extraction of mandibular wisdom teeth.

RESULTSIn the vertical impaction group, the operation time, the degree of swelling, limitation of mouth opening and the pain degree were (8.2 ± 2.5) min, (14.7 ± 2.0) mm, (3.9 ± 2.4) mm and 3.4 ± 1.8, respectively using crown cutting, and (14.0 ± 2.7) min, (18.2 ± 1.9) mm, (9. 7 ± 3.6) mm and 6.9 ± 2.3 using traditional extraction method (P < 0.05). In the horizontal impaction group, the operation time, degree of swelling, limitation of mouth opening and pain degree (14.0 ± 2.0) min, (19.2 ± 3.9) mm, (9.5 ± 2.5) mm, 5.6 ± 1.7 respectively using crown "T"-shaped cutting, and (18.0 ± 3.1) min, (23.6 ± 3.5) mm, (9.8 ± 2.7) mm and 8.5 ± 2.3 using crown three section cutting. There was significant difference in operation time, degree of swelling and pain (P < 0.05), but no significant difference in the limitation of mouth opening (P > 0.05). In mesioangular impaction group, operation time, degree of swelling, limitation of mouth opening and pain degree were (10.2 ± 2.6) min, (18.4 ± 2.9) mm, (6.4 ± 2.5) mm and 4.8 ± 1.8, respectively using "T"-shaped cutting, and (15.0 ± 3.5) min, (18.9 ± 3.0) mm, (7.0 ± 3.7) mm and 7.6 ± 2.3 using crown- root cutting. The operation time and pain degree were significantly different (P < 0.05), but not different in limitation of mouth opening and swelling degree (P > 0.05).

CONCLUSIONSDifferent impaction types of wisdom teeth should choose different cutting mode. Vertical impacted tooth uses distal crown cutting. "T"-shaped cutting is preferred with horizontal impaction. According to the angle and depth of the mesioangular impaction, "T"-shaped cutting or the crown-root cutting can be selectively used.

OBJECTIVE: To investigate the expression and clinical significance of microRNA-195 in patients with diffuse large B cell lymphoma(DLBCL). METHODS: Sixty patients with DLBCL were selected from nearly four years in our hospital, and at the same time 30 healthy people with physical examination of the same period and with the same age in our hospital were choosed as control group. Real-time fluorescent quantitative PCR (RT-qPCR) was used to detect the miR-195 expression of the patients and controls, the relationship between miR-195 expression and clinicopathological characteristics of DLBCL and survival time of patients was analyzed. RESULTS: The expression level of miR-195 in DLBCL patients was significantly lower than that in the controls (P<0.001). The expression level of miR-195 closely related with tumor diameter, IPI score and Ann Arbor stage of patients with DLBCL. Overall survival(OS) time of DLBCL patients with highly expressed miR-195 was significantly longer than that of patients with low expression (P<0.001). CONCLUSION miR-195 expression decrease in DLBCL patients, and miR-195 closely relates with tumor characteristics of patients with DLBCL. DLBCL patients with higher expression of miR-195 show longer overall survival time.

Recent studies showed that pathology of alcoholic encephalopathy was associated with cerebral vascular damage. TMP (tetramethyl- pyrazine) is widely used in the treatment of cerebrovascular diseases, however, it has not been reported whether TMP can relieve alcohol-induced cerebral vascular damages. The study was performed to investigate the learning and memory, cerebrovascular pathological changes and the expressions of vascular endothelial growth factor (VEGF) and serum levelsofendothelin-1 (ET-1) in the rat model of chronic alcoholic encephalopathy, and explore the effects of TMP intervention on alcoholic encephalopathy. In the present study, the rat model of chronic alcoholic encephalopathy was established by the gavage administration of alcohol; the learning and memory ability was tested by Morris water maze; the expression of VEGF was measured by RT-PCR and Western blot; and the serum levels of ET-1 was measured by radioimmunoassay. We found that alcohol intoxication impaired learning and memory, induced VEGF overexpression and increased ET 1 concentrations. TMP intervention improved learning abilities, increased the VEGF expression and reduced ET-1 level. These results indicate that TMP exhibits therapeutic effects on chronic alcoholic encephalopathy.

OBJECTIVETo observe the TCR V gamma gene repertoire diversity in the peripheral blood mononuclear cells of the patients with the chronic benzene poisoning.

METHODSComplementarity determining region 3 (CDR3) of TCR V gamma subfamily genes were amplified in 10 patients with the chronic benzene poisoning using RT-PCR. The PCR products were further analyzed by genescan to evaluate clonality of T cells. 8 healthy persons served as control.

RESULTSAll V gamma subfamilies were detected in the 8 healthy donors. (1.30 +/- 0.48) V gamma subfamilies were detected in 10 patients. The number of detectable V gamma subfamilies present in the patients with the chronic benzene poisoning was significantly lower than in the control group (P < 0.01). The most frequently used V gamma genes in clonally expanded T-cells were V gamma II.

CONCLUSIONSkewed distribution and clonal expansion of TCR V gamma subfamily T cells could be found in the patients with the chronic benzene poisoning. This is the first report of clonal expansion TCR V gamma T cells in patients with chronic benzene poisoning. The bias pattern of TCR V alpha T cells may be due to the immune cytotoxicity from benzene.
