Respiratory diseases are common， frequently-occurring clinical diseases. As the prevalence rate is increasing year by year， they have become a problem that seriously affects public health. The diseases are mainly located in the lung by traditional Chinese medicine （TCM） syndrome differentiation. Lung governs Qi and controls breathing and is also an organ for the storage of phlegm. Clinically， phlegm and Qi are often used for the treatment. Banxia Houputang （BHT）， originated from Synopsis of the Golden Chamber （《金匮要略》）， was used to treat plum-stone Ai （globus hystericus） at first. It is composed of Rhizoma Pinelliae， Cortex Magnoliae Offcinalis， Poria， Rhizoma Zingiberis Recens， and Folium Perillae， and treats diseases with the core pathogensis of mutual obstruction of phlegm and Qi. BHT has the effects of moving Qi， dissipating mass， descending adverse Qi， and resolving phlegm， which basically correspond to the pathological characteristics of the lungs. Clinical studies have confirmed that modified BHT can be used either alone or in combination with western medicine to treat chronic pharyngitis， asthma， chronic obstructive pulmonary disease， pneumonia， obstructive sleep apnea， upper airway cough syndrome and other respiratory diseases， with significant effects. It effectively improves the symptoms and signs of the diseases and reduces the recurrence rate. Basic research has shown that BHT plays anti-inflammatory， anti-oxidative stress， anti-apoptotic， autophagy-regulating， and iron overload-regulating roles by regulating the targets in multiple pathways. This paper， by combing the relevant literature in recent years， conducted a systematic review on BHT from the three aspects of syndrome analysis， clinical treatment research and mechanism research， with a view to providing theoretical basis and reference for the mechanism research of BHT in treating respiratory diseases and for expanding its clinical application.

ObjectiveTo investigate the intervention effect of Buzhong Yiqitang （BZYQT） on pulmonary inflammation in mice induced by chronic intermittent hypoxia （CIH） and preliminarily elucidate its mechanism. MethodForty healthy male C57BL/6 mice aged 6-8 weeks were randomly divided into the following groups： normoxia group， model group （exposed to CIH）， and low-， medium-， and high-dose BZYQT groups. The normoxia group was exposed to a normoxic environment， while the model group and the low-， medium-， and high-dose BZYQT groups were exposed to intermittent hypoxia. In the BZYQT groups， the BZYQT （8.1， 16.2， 32.4 g·kg^-1·d^-1） was administered orally 30 min before placing the mice in the hypoxic chamber， while the model group and the normoxia group received an equivalent volume of normal saline. After five weeks of modeling， pulmonary function of the mice was measured using an EMKA animal lung function analyzer， and lung tissue samples were collected after the pulmonary function tests. Hematoxylin-eosin （HE） staining was performed to observe the histopathological changes in the lung tissue of each group. Enzyme-linked immunosorbent assay （ELISA） was used to measure the levels of interleukin-6 （IL-6）， interleukin-8 （IL-8）， tumor necrosis factor-α （TNF-α） in the serum， as well as angiotensin Ⅱ （Ang Ⅱ） and angiotensin-（1-7） ［Ang（1-7）］ in lung tissue. Western blot and immunohistochemistry were used to detect the protein expression of IL-6， IL-8， TNF-α， angiotensin-converting enzyme 2 （ACE2）， and mitochondrial assembly receptor （Mas）. ResultCompared with the normoxia group， the model group showed significant abnormalities in lung function （P<0.05， P<0.01）， lung tissue changes， such as thickening of alveolar walls and inflammatory cell infiltration， increased levels of IL-6， IL-8， TNF-α in the serum and Ang Ⅱ in lung tissue （P<0.01）， decreased level of Ang（1-7） （P<0.01）， increased protein expression of IL-6， IL-8， and TNF-α， and decreased protein expression of ACE2 and Mas （P<0.05， P<0.01）. Compared with the model group， the BZYQT groups showed improvement in lung function （P<0.05， P<0.01）， and HE staining of lung tissue showed approximately normal alveolar wall thickness and reduced inflammatory cell infiltration. Immunohistochemistry and Western blot analysis showed a significant decrease in the expression of inflammatory-related proteins （P<0.05， P<0.01）， and a significant increase in ACE2 and Mas protein expression （P<0.05， P<0.01）. ConclusionBZYQT can improve lung injury in mice exposed to CIH by regulating the ACE2-Ang（1-7）-Mas axis to inhibit inflammatory responses.

Objective:To investigate the feasibility of blue velvet arena test (BVAT) in evaluating spatial memory function in patients with chronic insomnia disorder (CID).Methods:From June 1, 2021 to May 31, 2022, 62 CID outpatients or inpatients were enrolled continuously in the Department of Sleep Disorders, the Affiliated Chaohu Hospital of Anhui Medical University, and 56 good sleepers in the same period were enrolled to serve as controls. Pittsburgh Sleep Quality Index (PSQI) was used to assess their sleep quality. Montreal Cognitive Assessment Scale (MoCA), nine box maze test (NBMT), and BVAT were used to assess general cognition and memories.Results:Compared to the controls, the CID patients had increased PSQI score [15.0 (12.8, 16.0) vs 0 (0, 1.0); Z=-9.47, P<0.001], and decreased MoCA score [24.5 (21.5, 27.0) vs 27.0 (26.0, 28.0); Z=-4.18, P<0.001]; increased numbers of errors in the spatial working [1.0 (0.8, 2.0) vs 1.0 (0, 1.0); Z=-2.24, P<0.05], object working [1.5 (0.8, 3.0) vs 0 (0, 1.0); Z=-4.36, P<0.001] and object recognition [0 (0, 0) vs 0 (0, 0); Z=-2.10, P<0.05] memories in NBMT; and increased average erroring distance in BVAT [23.0 (16.4, 27.2) cm vs 18.7 (16.6, 20.7) cm; Z=-3.30, P<0.01]. Partial correlation analysis showed that in the CID patients, the average erroring distance in BVAT was positively correlated with erroneous numbers in spatial working memory in NBMT ( r=0.54, P<0.001). Principal components analysis showed that the average erroring distance of BVAT (load=0.844) and the errors of spatial working memory in NBMT (load=0.801) were jointly attributed to the first factor. Receiver operating characteristic curve analysis showed that the sensitivity of BVAT was higher than that of NBMT (0.575 vs 0.250, P<0.05) for spatial memory detection in total sample. Conclusion:The BVAT has a higher reliability in the functional assessment of spatial memory in CID patients.

OBJECTIVE: To analyze the clinical features of chronic myeloid leukemia (CML) with T315 I mutation (CML-T315I) and compare the effectiveness of different treatments. METHODS: We retrospectively analyzed the clinical data and outcomes of 19 patients with CML-T315I receiving different treatments. The T315 I mutations in these patients were detected by examination of BCR-ABL kinase domain (KD) mutation by RTQ-PCR and Sanger sequencing. The relapse following the treatments, defined as hematological, cytogenetic and molecular biological recurrences, were analyzed in these patients. RESULTS: Of the 19 patients with CML-T315I, 14 (73.7%) were in CML-CP stage at the initial diagnosis, and 13 (81.2%) were high-risk patients based on the Sokal scores. All the 19 patients were treated with TKI after the initial diagnosis, and during the treatment, 15 (78.9%) patients were found to have additional chromosomal aberrations, and 10 (52.6%) had multiple mutations; 13 (68.4%) of the patients experienced disease progression (accelerated phase/blast crisis) before the detection of T315I mutation, with a median time of 40 months (5-120 months) from the initial diagnosis to the mutation detection. After detection of the mutation, 12 patients were treated with ponatinib and 7 were managed with the conventional chemotherapy regimen, and their overall survival rates at 3 years were 83.3% and 14.2%, respectively ( < 0.001). CONCLUSIONS CML patients resistant to TKI are more likely to have T315I mutations, whose detection rate is significantly higher in the progressive phase than in the chronic phase. These patients often have additional chromosomal aberrations and multiple gene mutations with poor prognoses and a high recurrence rate even after hematopoietic stem cell transplantation. Long-term maintenance therapy with ponatinib may improve the prognosis and prolong the survival time of the patients.

Magnetic resonance imaging (MRI) data of 87 patients with suspected cervical posterior longitudinal ligament (PLL) rupture,who underwent cervical spine surgery in Luoyang Orthopedic Hospital from January 2015 to September 2017,were analyzed retrospectively.The criteria of MRI diagnosis for PLL rupture were the low signal image of the PLL on the posterior margin of the vertebral body,the discontinuity or continuous interruption,or the local highlighting signal on the T2 weighted image.According to intraoperative findings,the diagnostic accuracy of MRI for PLL rupture was examined.Among 87 patients,31 cases were diganosed as PLL rupture by preoperative MRI;and 38 cases were confirmed by intraoperative exploration,of whom 30 were diagnosed with MRI,and 8 were missed by MRI.The accuracy,sensitivity and specificity of MRI in the diagnosis of ruptured PLL were 0.90,0.79 and 0.98 respectively.MRI has a good diagnostic efficiency in PLL rupture,which can be used for preoperative investigation.

Objective To explore the role of long-term enriched environment in promoting the recovery of motor and social function in mice after ischemic brain injury. Methods Sixteen adult male ICR mice underwent permanent middle cerebral artery occlusion (MCAO). The first day after operation, they were divided into enriched environment group (n=8) and standard condition group (n=8). The mice were tested with modified Neurological Severity Score (mNSS), rotarod test and smart cage 7, 14, 21, 28 days after modeling. Results The score of mNSS and the result of rotarod test improved more in the enriched environment group than in the standard condition group 28 days after MCAO (t>2.927, P<0.05). The occupancy time in the middle of smart cage was longer in the enriched environment group than in the stan-dard condition group 7 to 28 days after MCAO (t>2.480, P<0.05) in the general move test. There was a trend of being more interested in strange mice in the enriched environment group than in the standard condition group, but the difference was not statistically significant (P>0.05) in the social behavior test; however, the occupancy time in the middle of smart cage was longer in the enriched environment group than in the standard condition group 14 to 28 days after MCAO (t>3.472, P<0.01), and the velocity of moving was higher 14 days after MCAO (P<0.05). Conclusion Enriched environment could promote the recovery of motor function, somehow of social function, in mice af-ter ischemic brain injury.

Objective To investigate the expressions of homeobox gene 10 (HOXD10) and analyze its clinical significance. Methods Expressions of HOXD10 protein was detected by immunohistochemistry SP method in 53 cases of colorectal carcinoma tissues and corresponding normal tissues which was fixed by 4% formalin and embedded by paraffin.It was analyzed that the relationship between the expression of HOXD10 protein and clinico-pathological features. Results The positive staining rate of HOXD10 protein in normal colorectal mucosal tissue (5.7%)was significantly lower than that incolorectal carcinoma tissue(64.2%),the difference was statistically sig-nificant(P<0.05). In colorectal cancer tissue,the positive rate of HOXD10 protein in high differentiation(53.8%), T1+T2(38.5%),Ⅰ+Ⅱ(54.3%)and no lymph node metastasis(55.3%)was lower than that in low differentiation (73.0%),T3+T4(72.5%),Ⅲ+Ⅳ(83.3%)and lymph node metastasis,the difference was statistically significant (P < 0.05). However,it was not statistically significant between the positive rate of HOXD10 protein and the gender,age,primary site and tumor size in colorectal cancer patients(P>0.05). Conclusion The expression of HOXD10 protein is closely related to the invasion and metastasis of colorectal cancer.

Objective To estimate the excess relative risk coefficients of stomach cancer for Chinese population attributable to ionizing radiation.Methods The excess relative risk and excess absolute risk coefficients of stomach cancer were estimated based on Life Span Study by using risk models developed by BEIR Ⅶ committee (Biological Effect of Ionizing Radiation).Guided by transportation methods from Life Span Study to Americans,we determined that transportation method for Chinese population includes both multiplicative and additive models with a weight of 0.7 and 0.3 respectively,on an arithmetic scale.Besides,curve fitting was used to obtain sex-age-specific stomach cancer baseline incidence based on Chinese cancer annual report.Then,Chinese excess relative risk coefficients of stomach cancer were obtained by substituting excess relative risk,excess absolute risk of Life Span Study and Chinese baseline incidence rate into risk transportation model.Results Excess relative risk coefficients of stomach cancer for Chinese population are 0.26/Sv for male and 0.64/Sv for female,whose exposure age is 30 years old and cancer age is 60 years old.Coefficients increase with decreased exposure age and cancer age.Conclusions Excess relative risk coefficients of stomach cancer for Chinese population are by larger higher than that of Life Span Study,and their sex-age tendency are similar.

Objective To estimate the averaged excess relative risk(ERR) in Chinese population based on the radiogenic cancer risk of leukemia in Japanese atomic bomb survivor cohort,and to discuss proper method suitable for risk transfer between populations.Methods Based on BEIR Ⅶ radiogenic cancer model and population transfer model,and the 2009 Chinese leukemia baseline rates given in 2012 Chinese Cancer Registry Annual Report,comparison was made of population incidences in seveal countries to adjust the weighting factors.Results The ERR of three subtypes of leukemia as a whole was obtained,and the weighting factors for risk transfer model was assumed.The additive factor for male was 0.2,and the multiplicative factor was 0.8,while the additive factor for female was 0.15,and the multiplicative factor was 0.85.Conclusions For the risk transfer between populations,weighting factor was adjusted as a whole to obtain the ERR value for estimating the risk to Chinese population.The risk transfer method suitable for Chinese population was obtained by using the incidence rate available for Chinese population to directly transfer radiation-induced leukemia risk to Chinese from Japanese.

ObjectiveTo explore the expression of miR-130b and RUNX3mRNA in human gastric carcinoma and the clinical significance. MethodsThe expression of miR-130b and RUNX3mRNA were detected by RT-PCR in 40 cases of gastric carcinoma and corresponding normal mucosa tissue. The expression of RUNX3protein was determined by immunohistochemistry SP method. ResultsThe expression of miR-130b was significantly up-regulated in gastric carcinoma than that in the adjacent normal gastric mucosa tissues (2.18 ± 3.75 ) vs.( 2.59 ± 3.45 ),P ＜ 0.05 ; The expression of RUNX3mRNA in gastric carcinoma tissues was significantly lower than that in adjacent normal gastric mucosa tissues( 8.76 ±2.82) vs.( 7.58 ± 2.87 ),P ＜ 0.05.The expression of miR-130b and RUNX3mRNA were positively correlated with lymph node metastasis and clinical stage ( P ＜ 0.05 ) ; No significant association was found between the expression and age,gender,tumor size,distant metastasis and depth of tumor invasion ( P ＞0.05 ).The expression of miR-130b was negatively correlated with RUNX3 protein expression in nuclei and cytoplasm (P ＜ 0.05 ).ConclusionsAbnormal expression of miR-130b and RUNX3mRNA correlates with prognosis of gastric carcinoma; Decreased RUNX3 protein expression may contribute to tumourigenesis.
