ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction （清肺渗湿汤） combined with western medicine for patients with bronchial asthma of heat wheezing syndrome， and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group， each group with 43 participants. The control group received conventional western medicine， and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group， 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness； secondary outcome measures included traditional Chinese medicine （TCM） syndrome score， asthma control test （ACT） score， pulmonary function indices such as forced expiratory volume in 1 second （FEV₁）， forced vital capacity （FVC）， peak expiratory flow （PEF）， serum inflammatory factor levels including interleukin-4 （IL-4）， tumour necrosis factor-α （TNF-α）， and high-sensitivity C-reactive protein （hs-CRP）， and immune function indices including CD3⁺， CD4⁺， CD8⁺， CD4⁺/CD8⁺. All outcome measures were evaluated before and after treatment. Vital signs were monitored， and electrocardiography， blood routine， urine routine， liver function， and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% （39/40）， which was significantly higher than that of the control group （85.0%， 34/40， P＜0.05）. After treatment， both groups showed decreased TCM syndrome scores， IL-4， TNF-α， hs-CRP， and CD8⁺ levels， as well as increased ACT scores， CD3⁺， CD4⁺， CD4⁺/CD8⁺， FEV₁， FVC， and PEF levels （P＜0.05 or P＜0.01）. Moreover， the improvements in these indices were more significant in the treatment group than in the control group （P＜0.05 or P＜0.01）. No significant abnormalities in safety indicators were observed in either group， and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms， pulmonary function， and clinical effectiveness， with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

Objective To investigate the effect of tetrandrine tablets on inflammatory cytokines and acute phase response following the first-dose of zoledronic acid in postmenopausal osteoporosis patients. Methods 80 postmenopausal osteoporosis patients receiving the first-dose of zoledronic acid admitted in the Affliated Xuzhou Municipal Hospital of Xuzhou Medical University from June, 2022 to December, 2024 were selected as study objects, and the patients were randomly divided into control group （40 cases, prophylactic treatment with acetaminophen tablets） and study group （40 cases, prophylactic treatment with tetrandrine tablets and acetaminophen tablets）. The high-sensitivity C-reactive protein （hs-CRP）, interleukin-1β （IL-1β）, IL-6, tumor necrosis factor-α （TNF-α） and the occurrence of acute phase reactions （fever, muscle and joint pain, gastrointestinal discomfort） between two groups were compared. Results The levels of serum hs-CRP, IL-1β, IL-6, and TNF-α in both groups significantly increased on day 1 and day 3 after infusion of zoledronic acid （all P values <0.05）. The levels of serum hs-CRP, IL-6, and TNF-α in the control group were higher than those in the study group on day 1 and 3 after infusion of zoledronic acid, with statistical significance （all P values <0.05）. In terms of acute phase reactions, the incidence of fever, muscle and joint pain in the control group after infusion of zoledronic acid were higher than those in the study group, with statistical significance （P<0.05）. No statistically significant difference in the incidence of gastrointestinal discomfort between the two groups （P>0.05）. Conclusion Tetrandrine tablets could reduce the expression levels of hs-CRP, IL-1β, IL-6, and TNF-α following the first-dose of zoledronic acid in postmenopausal osteoporosis patients, reduce the incidence of acute phase reactions, and alleviate adverse reactions.

BACKGROUND:Platelet-rich fibrin(PRF)has many advantages,such as simple preparation,low production cost,and high safety,and has been widely used in the study of bone defect repair in oral and maxillofacial surgery,but there are problems such as too fast degradation rate and short release time of growth factors. OBJECTIVE:PRF was loaded into gelatin methacryloyl(GelMA)hydrogel and its osteogenic properties were analyzed by in vivo and in vitro experiments. METHODS:(1)New Zealand white rabbit venous blood was extracted to prepare PRF.GelMA hydrogels containing 0,0.05,0.075,and 0.1 g PRF were prepared,respectively,and were recorded as GelMA,GelMA/PRF-0.05,GelMA/PRF-0.075,and GelMA/PRF-0.1,respectively,to characterize the micromorphology and in vitro slow-release properties of the hydrogels.(2)Four kinds of hydrogels were co-cultured with MC3T3-E1 cells,respectively,and the cell proliferation activity was detected with the single cultured cells as the control.After osteogenic induction,alkaline phosphatase activity,mineralization ability,mRNA and protein expression levels of osteogenic genes(osteocalcin,osteopontin,RUNX2),ERK1/2-p38 MAPK pathway protein mRNA and protein expression levels were detected.(3)Fifteen New Zealand white rabbits were taken.Four full-layer bone defects of 8 mm diameter were prepared in the skull of each rabbit,one of which was implanted without any material(blank control group),and the other three were implanted with GelMA hydrogel,PRF,and GelMA/PRF-0.1 hydrogel,respectively.The bone defect was detected by Micro-CT and bone morphology was observed at 4,8,and 12 weeks after operation. RESULTS AND CONCLUSION:(1)Scanning electron microscopy observed that all the hydrogels of the four groups had honeycomb pore structure,and the pore size of the hydrogels decreased slightly with the increase of PRF content,but there was no significant difference between the groups.The three groups of GelMA/PRF hydrogel could release transforming growth factor β1 and insulin-like growth factor 1 at a certain rate,and the cumulative release of transforming growth factor β1 and insulin-like growth factor 1 increased significantly with the extension of time.(2)CCK-8 assay and live/dead staining showed that GelMA/PRF hydrogel could promote the proliferation of MC3T3-E1 cells.The results of alkaline phosphatase staining,alizarin red staining,and osteogenic gene detection showed that GelMA/PRF hydrogel could promote the osteogenic differentiation of MC3T3-E1 cells,and inhibit the expression of ERK1/2-p38 MAPK pathway protein,and showed a PRF content dependence.(3)Micro-CT scan showed that the bone mineral density and bone volume fraction in the bone defect of GelMA/PRF-0.1 hydrogel group were higher than those in the other three groups(P<0.05).Hematoxylin-eosin staining showed that compared with the other three groups,GelMA/PRF-0.1 hydrogel group had faster and more mature new bone formation at the bone defect.(4)These findings indicate that GelMA/PRF hydrogel has good osteogenic activity both in vivo and in vitro,which may be related to inhibiting the expression of ERK1/2-p38 MAPK pathway protein.

This paper summarized Professor ZHOU Zhaoshan's clinical experience in treating bronchial asthma （abbreviated as asthma） by stages with dampness-draining method. It is believed that pathogenic dampness is the key pathological factor in the onset of asthma. Dampness accumulates into water， which gathers into rheum； the condensed rheum forms phlegm， which lingers in the lungs. When external pathogens trigger the latent phlegm， phlegm and qi become mutually obstructed， leading to airway obstruction， disrupted qi movement， and upward reversal of lung qi， thereby resulting in asthma attacks. The treatment emphasizes a stage-based approach. During acute attacks， the main syndromes include cold-damp obstructing the lungs， damp-heat accumulating in the lungs， and shaoyang （少阳） constraint with heat. For the syndrome of cold-damp obstructing the lungs， a self-formulated Wenfei Shenshi Decoction （温肺渗湿汤） is used to warm the lungs and disperse cold， drain dampness and relieve panting； for the syndrome of damp-heat accumulating in the lungs， a self-formulated Qingfei Shenshi Decoction （清肺渗湿汤） is employed to clear the lungs and expel heat， drain dampness and relieve asthma； and for the syndrome of shaoyang constraint with heat， a self-formulated Chaihu Shenshi Decoction （柴胡渗湿汤） is administered to harmonize the shaoyang， clear heat and drain dampness. During the remission stage， treatment is based on the underlying kidney-deficiency constitution， and a self-formulated Bushen Shenshi Decoction （补肾渗湿汤） is formulated to tonify the kidneys and drain dampness， improve qi reception and relieve panting.

Objective The aim of this study is to retrospectively analyze the clinical and imaging characteristics,treatment and prognosis of 13 patients with granulomatous prostatitis(GP),and to provide reference for the diagnosis and treatment for GP.Methods The clinical information of 13 GP patients extracted from electronic medical records including demographic characteristic risk factors,clinical symptoms,laboratory findings,imaging findings(ultrasound,CT,MRI,FDG-PET-CT),treatment and outcomes were analyzed retrospectively from January 2018 to August 2023 at our center.Results The average age of 13 patients with GP was(65.69±6.46)years.And the average score of IPSS was(23.40±5.8).Five patients appeared positive results,of which 11 cases received digital rectal examination.The average level of pre-biopsy tPSA was(23.28±44.94)μg/L with fPSA/tPSA ratio of 0.11±0.05 and PSAD of(0.55±1.07)μg/l/mL.The pre-biopsy mean MRI PI-RADS 2.0 was(4.6±0.6)in this group of patients.Extraprostatic invasion was shown on imaging in 4 patients.The average number of biopsy needles was(19.6±3.9),and the pathological results showed tuber-culous granulomas in 2 cases(15.4％)and non-specific granulomatous inflammation in 11 cases(84.6％).Five patients received local treatment of the prostate after pathological confirmation(PVP in 4 cases,TURP in 1 case),2 patients re-ceived anti-tuberculosis therapy,and 3 cases were given antibiotics.Average follow-up was(20.6±11.2)months,and the average tPSA were(6.94±4.96)μg/L at 3-6 months after biopsy and/or surgery,with no obvious signs of malignancy during the follow-up period.Conclusion GP is the great mimicker of prostate cancer clinically and radiologically.Pros-tate biopsy is the method for confirming the diagnosis.For patients who are considering biopsy-free radical prostatectomy,it is important to consider the possibility of GP.

Neuronal intranuclear inclusion disease（NIID）is a rare hereditary neurodegenerative disorder that can affect multiple systems. However，it is uncommon for urinary dysfunction to be the initial symptom. This article reports five cases. The five patients began to experience voiding dysfunction such as frequent urination，weak urination，and incomplete urination at the mean ages of 55.4（47 - 65）years old. Four months to twelve years after urinary onset，neurological symptoms such as headache，memory decline，transient loss of consciousness，and unsteady gait began to appear. Four of the five cases had a family history. Brain MRI revealed the “ribbon sign” or “crest sign” in all cases. Skin biopsy revealed eosinophilic inclusions in the cell nuclei，and NOTCH2NLC gene testing identified abnormal GGC mutations. Three of the five patients underwent cystostomy due to secondary hydronephrosis，while the other two received no special treatment. After a follow-up of 18 to 35 months since diagnosis，the patients who underwent cystostomy had normal renal function. Neurological symptoms in all five patients worsened to varying degrees.

Objective:To explore the application of triplet-primer PCR (TP-PCR) for the genetic testing and prenatal diagnosis in patients with Myotonic dystrophy type 1 (DM1).Methods:A total of 60 individuals from 48 pedigrees undergoing genetic testing at the Genetic and Prenatal Diagnosis Center of the First Affiliated Hospital of Zhengzhou University from May 2018 to October 2022 were selected as the study subjects. TP-PCR combined with capillary electrophoresis was applied to determine the number of CTG repeats of the DMPK gene, and prenatal testing was provided to four DM1 pedigrees. This study was approved by Medical Ethics Committee of the First Affiliated Hospital of Zhengzhou University (Ethics No. KS-2018-KY-36). Results:A total of 52 DM1 patients were detected, mostly with muscle weakness, muscular atrophy and myotonia as the initial symptoms, along with typical myotonic potentials. Some patients also had abnormalities of other systems. The number of abnormal CTG repeats of the DMPK gene was > 50, whilst the number of CTG repeats on the normal allele had ranged from 5 to 18. The number of the most common normal CAG repeats was 6 (30.77%, 16/52). Among the four DM1 pedigrees undergoing prenatal diagnosis, one fetus was healthy, whilst three fetuses were found to have abnormal CTG repeats (> 50 times) and diagnosed with DM1. Conclusion:TP-PCR can diagnose DM1 patients with speed and accuracy. However, this method cannot accurately determine the number of CTG repeats when it exceeds 50.

Objective:To explore the genetic basis for a Chinese pedigree affected with Fragile X syndrome (FXS) through Nanopore long-read sequencing.Methods:A FXS pedigree who had undergone genetic counseling at the First Affiliated Hospital of Zhengzhou University in April 2023 was selected as the study subject. Nanopore long-read sequencing, triplet-repeat primed PCR (TP-PCR), methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) and trinucleotide polymorphism genotyping of androgen receptor (AR) gene were used to analyze the FMR1 CGG repeat number, methylation, and X chromosome inactivation of the pedigree members. This study has been approved by the Medical Ethics Committee of the First Affiliated Hospital of Zhengzhou University (No. KS-2018-KY-36). Results:Full mutation and CpG island hypermethylation were detected in the proband. The elder sister of the proband had full mutation of the FMR1 gene on one X chromosome and hypermethylation of CpG island, while the FMR1 gene on the other X chromosome was normal. FMR1 premutation was detected in the proband′s mother. Conclusion:Nanopore long-read sequencing can simultaneously detect the dynamic mutation and methylation status of the FMR1 gene on the two X chromosomes of females, which has important value for the diagnosis of FXS in different genders.
