ABSTRACT
@#Skeletal angle class Ⅲ malocclusion with mandibular deviation involves the rotation and translation of the cranial base, maxilla, mandible, and soft tissue. It compromises the patients’ appearance and stomatognathic function. The treatment outcome is not satisfactory, and correct evaluation is of great significance. The causal relationship between skeletal Class Ⅲ with mandibular deviation and TMD remains controversial. This review focuses on the structural alterations of hard and soft tissue, the etiology, the choice of treatment methods, and the association with TMD in patients with skeletal class Ⅲ malocclusion with mandibular deviation. The results show that mandibular deviation is a complex disease with unclear etiology. It involves morphological changes, rotation and displacement of the cranial base, maxilla and mandible, morphological changes of the soft tissue, and occlusal changes, which also compromise the temporomandibular joint and mandibular function. Skeletal Class Ⅲ malocclusion is common in patients with mandibular deviation. Early treatment is needed; however, the treatment methods vary. The correct evaluation of the morphological changes of soft and hard tissues leading to facial asymmetry is the premise of treatment. Orthodontic and orthognathic treatment (combined with soft tissue repair when necessary) is an effective method for the treatment of skeletal class Ⅲ malocclusion with mandibular deviation. In addition, there is a close relationship between mandibular deviation and TMD, which needs to be fully considered in the design of treatment.

ABSTRACT
Influenza viruses exacerbate chronic obstructive pulmonary disease (COPD) with considerable morbidity and mortality. Zanamivir and oseltamivir are effective in treating influenza. However, their efficacy in relieving influenza symptoms in COPD patients remains unknown, with the lack of controlled trials in this subject. Therefore, we conducted this randomized controlled trial to investigate the clinical efficacy of both interventions in this population. Patients were allocated to two groups (80 patients each): oseltamivir (OSELTA) and zanamivir (ZANA) groups. Oseltamivir (75 mg) was orally administered twice daily for 5 days, while zanamivir (10 mg) was inhaled twice daily for 5 days. Clinical parameters including body temperature, influenza symptoms (i.e., sore throat, cough, etc.), and serial blood tests were recorded on days 1, 3, and 7. We analyzed primary (changes in body temperature) and secondary outcomes (changes in non-specific symptoms) using the pre-protocol and intention-to-treat analyses. Differences between groups were assessed using t-test. Oseltamivir and zanamivir significantly reduced body temperature on the 3rd day after treatment; however, the number of patients who reported clinical improvement in influenza-like symptoms was significantly higher in the OSELTA group compared to the ZANA group on days 3 (85 vs 68.8%, P=0.015) and 7 (97.5 vs 83.8%, P=0.003). However, no significant changes in hematological (white blood cells and its subtypes) and inflammatory (C-reactive protein) parameters were noted (P>0.05). Our results suggested that oseltamivir and zanamivir are effective in reducing body temperature, while oseltamivir led to better clinical improvement regarding influenza-like symptoms in patients with COPD.

Aim: This study aimed to investigate the predictive power of the combination of Systemic Immune-Inflammation Index (SII) and albumin-bilirubin (ALBI) grade in prognosis outcomes of early-stage hepatocellular carcinoma (HCC) after thermal ablation. Materials and Methods: This retrospective study was reviewed and approved by our institutional review board, and written informed consent was obtained from each patient. According to the Milan criteria, a total of 405 treatment-naïve patients with clinicopathologically confirmed HCC were enrolled who subsequently underwent thermal ablation from 2011 to 2016. The outcomes of overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) were statistically analyzed. Results: The median follow-up time of this study was 45.1 months (range, 1.3–83.2 months). After thermal ablation in patients with SII-ALBI Grades 1, 2, and 3, the cumulative 5-year OS rates were 81.7%, 63.2%, and 26.9%; the 5-year CSS rates were 82.4%, 67.5%, and 26.9%; and the 5-year RFS rates were 49.3%, 44.6%, and 25.3%, respectively (all P < 0.001). On multivariate Cox regression analyses, SII-ALBI was independently associated with the three outcomes after adjustment for various confounders (all P < 0.05). In addition, SII-ALBI played a predictive role in OS, CSS, and RFS for patients with negative alpha-fetoprotein (AFP) (P < 0.05). Compared with SII and ALBI, the AUCs for the prediction of OS and CSS using SII-ALBI were superior to single indicator (bothP < 0.05). Conclusion: Elevated preablation SII-ALBI is associated with shorter OS, CSS, and RFS in patients with early-stage HCC. Our indicator showed the potential to be a supplement tool for patients with negative AFP during follow-up
ABSTRACT
To compare the efficacies of the two techniques of "micro-hemostasis and micro-cutting" with straight bipolar electrocoagulation forceps and traditional clamp-ligation for hemostasia in thyroid surgery. A total of 228 patients who underwent surgical treatment for thyroid neoplasms in our hospital between January 2015 and December 2018 were retrospectively analyzed, including 50 males and 178 females, aged 23-68 years old. Of those, 150 cases as electric knife group received traditional thyroid surgery between January 2015 and December 2018 and 78 cases as bipolar electrocoagulation group received thyroid surgery by using the technique of bipolar electrocoagulation with meticulous anatomy between January 2018 and December 2018. The total operation time, single operation time, intraoperative hemorrhage, postoperative drainage volume on the first day, postoperative hoarseness and hypocalcemia were compared between the two groups. SPSS 16.0 was used to analyze the data. The total operation time and intraoperative hemorrhage in the bipolar electrocoagulation group were significantly lower than those in the electric knife group ((59.33±18.29)min (77.21±25.39)min, (14.83±9.22)ml (36.86±11.80)ml, all 0.01). The single operation time of the bipolar electrocoagulation group was shorter than that of the electric knife group((10.25±6.16) min (20.34±7.24)min, (16.25±7.15)min (35.68±8.25)min, (12.12±5.25)min (20.68±7.26)min, value was 3.948,16.262,8.238, all 0.01).There was no significant difference between the two groups in postoperative drainage volume on the first day (0.05) and the incidence of postoperative hoarseness (0.05), while the incidence of hypocalcemia in the bipolar electrocoagulation group(10.26%) was lower than that in the electric knife group(21.33%,χ(2)=4.353, 0.05). The fine dissection for thyroid operation can be achieved by using straight bipolar electrocoagulation tweezers. The use of "micro-hemostasis" and "micro-cutting" technique with bipolar electrocoagulation tweezers can greatly reduce intraoperative bleeding, operation time and postoperative complication.
ABSTRACT
@#[Abstract] Objective: To explore the role of adhesion molecule with Ig like domain 2 (AMIGO2) in the proliferation of nasopharyn‐ geal carcinoma (NPC) cells and its mechanisms. Methods: A total of 10 NPC tissue samples and 10 normal nasopharyngeal epithelial tissue samples collected at Fujian Cancer Hospital during September 2017 and November 2017 were used for this study; in addition, NPC cell lines (CNE-1, CNE-2, SUNE-1, 6-10B, C666-1) and human immobilized nasopharyngeal epithelial cell line NP69 were also collected. The relative expression of AMIGO2 mRNAin above mentioned tissues and cell lines was detected by qPCR. Lentivirus vectors were constructed to interfere AMIGO2 mRNA expression, and qPCR was used to verify its interference efficiency. CCK-8 method, Clonal formation and Flow cytometry were performed to evaluate the effect of AMIGO2 interference on proliferation, clone formation and apoptosis of NPC cells. The influence of AMIGO2 interference on PI3K/AKT/mTOR signaling pathway and proliferation related molecular markers in NPC cells was assessed by Western blotting. Results: The results of qPCR showed that AMIGO2 was highly expressed in NPC tissues, CNE-2, and SUNE-1 cells (all P<0.01). The interference efficiency of AMIGO2 in CNE-2 and SUNE-1 cells could reach over 50%. The interfering of AMIGO2 expression significantly inhibited the proliferation and clone formation of CNE-2 and SUNE-1 cells (all P<0.01), promoted cell apoptosis (all P<0.01), reduced the phosphorylated protein expression levels of PI3K, AKT and mTOR in SUNE-1 cells (all P<0.01), as well as down-regulated the protein expressions of survivin and PCNA (all P<0.01). Conclusion: AMIGO2 may promote the proliferation as well as inhibit apoptosis of NPC cells by activating the PI3K/AKT/mTOR signaling pathway, suggesting that AMIGO2 may be a potential target for NPC therapy.
ABSTRACT
@# Objective: To study the effect of ipilimumab on T lymphocytes and Bcl-2 mRNA expression in lung cancer-bearing mice by inhibiting TGF-β1/ERK signaling pathway. Methods: Forty-five C57 mices inoculated with Lewis lung cancer cells were randomly divided into control group, low dose ipilimumab group and high dose ipilimumab group with 15 mice in each. The low and high dose groups were given 3 mg/kg and 5 mg/kg ipilimumab respectively, while the control group was given 0.9% sodium chloride solution with the same volume. The effects of ipilimumab on TGF-β1/ERK signaling pathway, Bcl-2 mRNA expression, immune function improvement and tumor inhibition in three groups were detected by WB and qPCR. Results: After administration of ipilimumab, the tumor weight and volume of mice in low-dose and high-dose groups were significantly lower than that of the control group, and the tumor inhibition rate increased in a dose-dependent manner (P<0.05). The thymus index and spleen index of mice were significantly higher than that of control group, which also increased in a dose-dependent manner (P<0.05). The levels of CD3+, CD4+, CD4+/CD8+ cells in the high and low dose groups were significantly higher than those in the control group, with significantly higher levels in high dose group compared with the low dose group (P<0.05). The levels of serum inflammatory factors were significantly lower than those in control group, and the levels of serum TNF-α, IL-6 and IL-3 in the high dose group were significantly lower than those in the low dose group (P<0.05). The expressions of TGF-β1, ERK1/2, p-ERK1/2 and MEK in tumor tissues of both high and low dose groups significantly decreased, with more lower levels in high dose group than in low dose groups (all P<0.05), and the positive rate of TGF-β1 expression in high dose group was the lowest. The mRNAexpression of Bcl-2 in tumor tissues of high and low dose groups decreased significantly after drug administration, with a significantly lower level in high does group than that in low dose group (P<0.05). Conclusion: Ipilimumab can effectively inhibit TGF-β1/ERK signaling pathway, improve immune function and down-regulate the expression of Bcl-2, thus inhibit the growth of Lewis lung cancer cells and play an antitumor role in mice.
ABSTRACT
Objective @#To study the anatomical characteristics of the root and root canal system of the mandibular second permanent molar in the Uygur people and provide a reference for clinical practice.@*Methods @#A total of 125 mandibular second permanent molars were extracted from Uygur patients in hospitals in the Xinjiang Uygur Autonomous Region. Three-dimensional reconstruction was performed after micro-CT scanning. The number of root canals, the root canal type (Weine classification and Fan′s C-shaped canal classification) and the occurrence of lateral accessory canals were observed.@*Results @#A sex difference was not detected in the root number or root form (χ2 = 1.277, P = 0.259). The incidence of 2-rooted molars was 70.4% (n = 88); type 2-1 canals were most common in the mesial root, with an incidence of 29.5%, followed by type 1-1 and 2-2 canals (each with an incidence of 26.1%), and the distal root mostly had a type 1-1 canal (96.6%). The incidence of single-rooted molars was 28.8%, and the frequency of C-shaped (n = 28) and non-C-shaped (n = 8) single-rooted molars was 22.4% and 6.4%, respectively. A three-rooted molar was detected in one case. The incidence of accessory canals was 65.2%.@*Conclusion @# Uygur mandibular second molars are mainly composed of two roots, and the incidence of a single root and root canal fusion is low (including C-shaped canals). Two-rooted molars frequently have two mesial canals and one distal canal.
ABSTRACT
Objective To explore the ability of clinical nursing students responding to influenza by questionnaire to give scientific data for increasing this ability. Methods Questionnaire, including individual information, the knowledge, attitude and practice (KAP) towards influenza, was given to clinical nursing students in Peking Union Medical College Hospital. The KAP was described by descriptive analysis and the risk factors for the KAP score was analyzed by multiple linear regression. Results This study involved 278 clinical nursing students from Peking Union Medical College Hospital. The average score of KAP was 16.05 ± 9.91. The results of multiple linear regression showed that the KAP score has high positive correlation with the department, the duration of practicing, the information source of influenza prevention or control, and influenza individuals (P<0.01). Conclusions The ability of clinical nursing students towards influenza is not satisfying. The Hospital and Medical schools should pay much attention on training. The hospitals should take their clinical advantages, analyze the KAP risk factors and design scientific interference to strengthen education, which will urge clinical nursing students paying more attention to influenza, increasing their responding ability and decreasing the case rate.
ABSTRACT
Background: Although the functional redundancy of catechol 1,2-dioxygenase (C12O) genes has been reported in several microorganisms, limited enzymes were characterised, let alone the advantage of the coexistence of the multiple copies of C12O genes. Results: In this study, four novel C12O genes, designated catA, catAI, catAII and catAIII, in the naphthalene-degrading strain Pseudomonas putida ND6, were cloned and characterised. Phylogenetic analysis of their deduced amino acid sequences revealed that the four C12O isozymes each formed independent subtrees, together with homologues from other organisms. All four enzymes exhibited maximum activity at pH 7.4 and higher activity in alkaline than in acidic conditions. Furthermore, CatA, CatAI and CatAIII were maximally active at a temperature of 45°C, whereas a higher optimum temperature was observed for CatAII at a temperature of 50°C. CatAI exhibited superior temperature stability compared with the other three C12O isozymes, and kinetic analysis indicated similar enzyme activities for CatA, CatAI and CatAII, whereas that of CatAIII was lower. Significantly, among metal ions tested, only Cu2+ substantially inhibited the activity of these C12O isozymes, thus indicating that they have potential to facilitate bioremediation in environments polluted with aromatics in the presence of metals. Moreover, gene expression analysis at the mRNA level and determination of enzyme activity clearly indicated that the redundancy of the catA genes has increased the levels of C12O. Conclusion: The results clearly imply that the redundancy of catA genes increases the available amount of C12O in P. putida ND6, which would be beneficial for survival in challenging environments.

Abstract: We report a 12-year-old girl who presented with recurrent angioedema on the face, trunk, and extremities, and concomitant marked weight gain for 5 years. During the episode, her white blood cell count increased to 47.7×109/L with 89.9% eosinophils, followed by elevated serum level of IL-5, IgE, IgM, and LDH. Histopathology showed perivascular eosinophilic infiltration and diffuse eosinophilic infiltration throughout the dermis. Possible causes of hypereosinophilia and eosinophilic infiltration of vital organs were ruled out. We also tested the FIP1L1/PDGFRa and ETV6/PDGFRb fusion gene to exclude the possibility of myeloid and lymphatic vessel neoplasms. The patient was treated with methylprednisolone and discharged with an oral prednisolone taper, which resulted in complete remission of the edema and normalization of peripheral blood eosinophil count, serum IL-5 level, IgE, IgM, and LDH.

ABSTRACT
Drug resistance of multiple myeloma(MM) has become more and more common, and greatly decreased the survival rate of these patients. The occurence of drug-resistance involves in many factors such as bone marrow microenveronment, tumor cell self-metabolism, cytokines, specific targets and so on. In this review, the potential mechanisms of resistance to glucocorticoid/proteasome inhibitor/immunomodulatory druges are briefly expounded in the aspect of tumor cell self-metabolism, including the changes of heat slock protein expression, mRNA expression, related cytokine levels and down-regulation of thalidomid-effecting site CRBN expression. In this review, the researches on the effect of histone deacetylase inhibitors(HDACi) combined with glucocorticoid, proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies on multiple myeloma, specially, drug-resistant multiple myeloma are also summarized.
ABSTRACT
Abstract: We report an imported case of cutaneous leishmaniasis in a 37-year-old man from Saudi Arabia caused by Leishmania major. He presented with non-healing nodulo-ulcerative lesions with a "volcanic crater" on the lower limbs. It was clearly cutaneous leishmaniasis - a rare disease in China - as reflected by the patient's clinical history, the lesions' morphology, histopathological examination, culture and PCR analysis of the lesions. The patient was completely cured after two cycles of sodium stibogluconate treatment. This case report demonstrates that dermatologists should be aware of sporadic cutaneous leishmaniasis cases in non-endemic areas.

<p><b>OBJECTIVE</b>To explore the effectiveness and safety of combined chemotherapy with pegasparaginase (PEG-Asp) for treatment of patients with acute lymphoblastic leukemia (ALL) and T cell non-Hodgkin's lymphoma (T-NHL) patients.</p><p><b>METHODS</b>A total of 62 ALL or T-NHL patients were diagnosed and treated in our department and were enrolled in this study. Among them, 22 patients received the combined chemotherapy with PEG-Asp, while the other 40 patients received the standard chemotherapy with L-asparaginase (L-Asp) as the control. Therapeutic effectiveness, adverse effects, duration and expense of hospitalization, treatment-related mortality and survival were evaluated and compared in 2 different groups.</p><p><b>RESULTS</b>In group of combined chemotherapy with PEG-Asp, the overall response rate was 90.91% (20 cases), among them CR rate and PR rate are 77.27% (17 cases) and 13.64% (3 cases), respectively. In the group of standard chemotherapy with L-Asp, the overall response rate was 87.5% (35 cases), among them CR rate and PR rate were 72.5% (29 cases) and 15% (6 cases), respectively. The difference neither between PEG-Asp and L-Asp chemotherapy groups nor between ALL and T-NHL subgroups was significant (P > 0.05). The 6-month and 12-month overall survival rates were not significantly different between the PEG-Asp and L-Asp chemotherapy groups, respectively (P > 0.05). The adverse effects were identified as degree 1-2 according to the WHO criteria of drug toxicity. Neither the adverse effects identified as degree 3-4 nor the treatment-related death were observed. Expect for allergy and hyperglycaemia, the difference of side-effect incidence between the two groups were not significant (P > 0.05). The treatment for all the patients in PEG-Asp chemotherapy group was completed, while the treatment with L-Asp was completed only in 29 cases. Moreover, both average duration and expense of hospitalization after the combined chemotherapy were less than the control.</p><p><b>CONCLUSION</b>With higher response rate, lower drug toxicity and allergy incidence, the combined chemotherapy with PEG-Asp can replace the standard chemotherapy with L-Asp in the treatment of ALL and T-NHL. The optimization of the combined chemotheropeutic protocols for more cases and long-term survival rates need to further and deeply explorate.</p>

This article reviewes Keap1-Nrf2/ARE signal pathway in three perspectives:the basic structure including the structure of Nrf2, Keap1 and ARE, their involvement in anti-oxidative actions including the basic function of Keap1-Nrf2/ARE signal pathway and the downstream activation of phase II metabolic enzymes and antioxidant protein/enzyme, as well as their regulation mechanisms, such as decoupling, degradation, the latch and the hinge.
ABSTRACT
To investigate sub-health status of neonates in Heping Street Region and related risk factors. Then, 7436 maternal women admitted to hospital in Heping Street Region, Beijing were enrolled from October 2013 to September 2015, including 293 women, who gave birth to sub-health neonates. Questionnaire survey was conducted to collect maternal age, education degree, experiences and income, occupation, life habit, condition in pregnancy, condition in perinatal period, adverse reaction in pregnancy, etc. Finally, 281 effective questionnaires were regained with effective regain rate of 95.90%. Compared with the occurrence rate of sub-health neonates between local population and floating population, correlation analysis and multi-factor Logistic regression analysis were conducted on the influence factors of sub-health neonates. The occurrence rate of sub-health neonates among floating population is higher than that among local population [1.10% [59/2641] V.S. 4.88% [234/4795]] with significant difference [P<0.05]. Correlation analysis showed that the differences in mother's age, family income, education degree, harmful factors in contact environment, prenatal care, history of adverse pregnancy, unhealthy metal factor, gestational diabetes, diseases history in pregnancy, drug history in pregnancy, sexually transmitted disease, pregnancy hypertension, premature rupture of fetal membranes, and circular of umbilical cord performed statistical significance [P<0.05]. Moreover, mother's age, premature rupture of fetal membranes, disease history in pregnancy, drug history in pregnancy and pregnancy hypertension are the influence factors for the risk of sub-health neonates, while high family income and healthcare in pregnancy are protective factors from the risk of sub-health neonates. All of these differences showed statistical significance [P<0.05]. The occurrence of sub-health neonates among floating population is higher than that among local population. Mother's age, premature rupture of fetal membranes, disease history in pregnancy, drug history in pregnancy, and pregnancy hypertension are major risk factors of sub-health neonates. Therefore, these results help us to take corresponding measures to improve the quality of newly-born population
