ObjectiveTo investigate the potential mechanism of action of the Qufeng Tongqiao Cough-relieving Decoction （祛风通窍止咳方， QTCD） in the treatment of upper airway cough syndrome （UACS）. MethodsTwenty-four guinea pigs were randomly divided into blank group， model group， traditional Chinese medicine （TCM） group， and inhibitor group， with six guinea pigs in each group. Except for the blank group， guinea pigs were sensitized with ovalbumin and aluminum hydroxide via intraperitoneal injection， followed by ovalbumin nasal drops combined with smoke exposure to establish the UACS model. After modeling， the TCM group was administered QTCD 0.9 g/（100 g·d） by gavage， the inhibitor group received the transient receptor potential vanilloid receptor 4 （TRPV4） inhibitor GSK2193874 1 mmol/L， 5 min by nebulisation， and the blank group and model group were given 2 ml/（100 g·d） normal saline by gavage once daily. After 7 days of treatment， a cough provocation test was performed using 0.4 mol/L citric acid. The levels of IgE in serum and inflammatory cytokines， including interleukin-6 （IL-6）， interleukin-8 （IL-8） in serum， bronchoalveolar lavage fluid （BALF）， and nasal lavage fluid （NLF） were detected by enzyme-linked immunosorbent assay （ELISA）. Histopathological changes in lung and nasal mucosal tissues were observed by hematoxylin-eosin （HE） staining. Immunohistochemistry was used to detect the protein levels of TRPV4， substance P （SP）， and calcitonin gene-related peptide （CGRP） in lung and nasal mucosal tissues. Real-time polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of TRPV4， SP， and CGRP in lung tissues. ResultsHE staining showed significant structural damage and infiltration of inflammatory cells in the lung and nasal mucosal tissues in the model group， while the TCM group and inhibitor group showed improved pathological changes. Compared with the blank group， the model group showed increased cough frequency， serum IgE level， and IL-6 and IL-8 levels in serum， BALF， and NLF. The protein levels of TRPV4， SP， and CGRP in lung and nasal mucosal tissues and their mRNA expression were elevated （P＜0.05 or P＜0.01）. Compared with the model group， the TCM group and inhibitor group showed reduced cough frequency， serum IgE level， and TRPV4 and SP mRNA expression in lung tissues. The TCM group showed reduced IL-6 and IL-8 levels in serum， BALF， and NLF， and reduced TRPV4 and CGRP protein levels in lung and nasal mucosal tissues. The inhibitor group showed reduced IL-6 and IL-8 levels in serum， BALF， and NLF， reduced IL-6 in BALF， reduced IL-8 in NLF， and decreased TRPV4， SP， and CGRP protein levels in lung tissues and SP and CGRP protein levels in nasal mucosal tissues （P＜0.05 or P＜0.01）. Compared with the TCM group， the inhibitor group had increased serum IgE， IL-6， and IL-8 levels， increased IL-6 level in BALF， and increased IL-8 levle in NLF， but decreased SP protein level in lung tissues and increased TRPV4 and SP mRNA expression in lung tissues （P＜0.01）. ConclusionQTCD effectively reduces cough frequency in the UACS guinea pig model. Its mechanism may involve inhibiting the activation of the TRPV4 pathway， improving airway neurogenic inflammation， alleviating inflammatory responses， and reducing cough hypersensitivity.

Primary central nervous system lymphoma (PCNSL) is a rare and aggressive non-Hodgkin’s lymphoma that affects the brain, eyes, cerebrospinal fluid, or spinal cord without systemic involvement. The outcome of patients with PCNSL is worse compared to patients with systemic diffuse large B-cell lymphoma. Given potential mortality associated with severe immune effector cell-associated neurotoxicity syndrome (ICANS), patients with PCNSL have been excluded from most clinical trials involving chimeric antigen receptor T-cell (CAR-T) therapy initially. Here, we report for the first time to apply decitabine-primed tandem CD19/CD22 dual-targeted CAR-T therapy with programmed cell death-1 (PD-1) and Bruton’s tyrosine kinase (BTK) inhibitors maintenance in one patient with multiline-resistant refractory PCNSL and the patient has maintained complete remission (CR) for a 35-month follow-up period. This case represents the first successful treatment of multiline resistant refractory PCNSL with long-term CR and without inducing ICANS under tandem CD19/CD22 bispecific CAR-T therapy followed by maintenance therapy with PD-1 and BTK inhibitors. This study shows tremendous potential in the treatment of PCNSL and offers a look toward ongoing clinical studies.

Objective:To understand the changes of serum interleukin (IL)-2 and IL-6 in adult patients with Kashin-Beck disease (KBD) in Qinghai Plateau, and to provide scientific basis for scientific prevention and treatment of plateau KBD.Methods:According to the "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010), adult KBD patients and healthy people over 18 years old were selected as KBD group and control group, respectively, in KBD disease areas of Xinghai County and Guide County, Hainan Tibetan Autonomous Prefecture, Qinghai Province. Fasting cubital venous blood was collected from the people of two groups, and the levels of serum IL-2 and IL-6 were determined by enzyme-linked immunosorbent assay (ELISA).Results:A total of 193 people were surveyed, including 114 people in KBD group and 79 people in control group. There was no significant difference in age and sex ratio between the two groups ( t = 0.204, χ 2 = 2.547, P > 0.05). The serum IL-2 and IL-6 levels of the KBD group were (572.21 ± 172.92), (42.35 ± 15.86) pg/ml, respectively; compared with the control group [(511.28 ± 173.22), (51.96 ± 17.18) pg/ml], the differences were statistically significant ( t = 2.404, 3.999, P < 0.05). Conclusion:The serum IL-2 level is increased and IL-6 level is decreased in adult KBD patients in Qinghai Plateau, both of which may be involved in the inflammatory reaction of adult KBD.

Objective To investigate the application of body mass monitoring APP in continuation care of discharged patients with chronic heart failure (CHF).Methods From June, 2016 to June, 2017, 84 patients with CHF were randomly divided into control group and research group with 42 cases in each group. After discharge, the control group received routine continuation nursing and the body mass monitor APP was used to monitor the body mass and continue nursing in the research group. Results After six months of discharge, the N-terminal pro-B-type natriuretic peptide (NT-proBNP) level, and the score of Minnesota Life Heart Failure Quality (MLHFQ) were significantly lower in the research group than in the control group (t>4.712, P<0.001). The number of repeat hospitalizations was lower in the research group than in the control group (χ2=7.714, P<0.01).Conclusion The body mass monitoring APP could improve the symptoms of heart failure and reduce the readmission rate of discharged patients with CHF in continuation care.

With the rapid development of tumor subjects and the advance of medical technology,tumor mortality is declining in spite of the increase in tumor incidence.The male survivors pay more and more attention to their prognosis to improve the quality of their life.In the meantime,whether they could produce their own offspring become the main concern of tumor patients with good prognosis.However,until now,male tumor patients,their relatives,different social sectors and even some of our health workers,havent noticed the importance of fertility preservation and long-term fertility desires of male patients with tumor which will lead to declined or even irreversible sterility induced by the lack of fertility preservation before anti-tumor therapy.It's an important way to do fertility counseling,learn the risk of their treatment plans and choose the appropriate technique of fertility preservation which will improve prognosis quality of life of male tumor patients.This article will review the effects of tumor and the treatment on male fertility,their subjective needs and concerns,main methods for fertility preservation and the domestic and foreign research present situation.
