Obesity， a global chronic disease， is associated with adipose tissue dysfunction， which is one of the contributing factors to obesity. The cyclic adenosine monophosphate （cAMP） signaling pathway， a key regulator of lipid metabolism， plays a pivotal role in obesity development. Various of traditional Chinese medicine monomers， such as flavonoids， lignans， phenols， and terpenoids， as well as traditional Chinese medicine compound formulas like Xiaoyao powder， Shengmai powder， and Zexie decoction， can maintain energy homeostasis， balance adipose tissue function， regulate glucose metabolism， improve insulin resistance， and suppress inflammatory responses through cAMP signaling pathway regulation， thereby intervening in lipid metabolism for obesity treatment. Although a substantial amount of basic research has preliminarily elucidated the potential mechanisms by which traditional Chinese medicine intervenes in obesity through the cAMP signaling pathway， clinical translational research remains inadequate. There is an urgent need for large-sample， high-quality randomized controlled trials to validate these findings.

Objective:To investigate the incidence of collateral circulation in high-risk patients with sleep apnea and stroke treated by continuous positive airway pressure （CPAP） ventilation and to analyze the influencing factors. Methods:A total of 152 patients diagnosed with obstructive sleep apnea-hypopnea syndrome （OSAHS） combined with acute ischemic stroke （AIS） who were admitted to our hospital from January 2020 to June 2022 were selected for this study. Based on the apnea-hypopnea index （AHI）, the patients were divided into three groups: mild （n=44）, moderate （n=72）, and severe （n=36）. After treatment, the patients were further classified into a group without collateral circulation （n=30） and a group with collateral circulation （n=26）, which included those with moderate collateral circulation （n=69） and good collateral circulation （n=27）. Clinical data across the different groups were compared, and multiple factor analysis was performed to identify factors affecting the occurrence of collateral circulation. Results:The AHI and IL-6 levels in the severe group were significantly higher than those in the mild and moderate groups, while the levels of NO and PO2 were significantly lower in the severe group compared to the mild and moderate groups, with statistically significant differences among the three groups （P<0.05）. After treatment, all groups showed improvement, and the proportion of patients with collateral circulation was 84.09% in the mild group, 81.94% in the moderate group, and 72.22% in the severe group. Significant differences in age, AHI, NIHSS, NO, MoCA, and MMSE scores were observed between the groups with and without collateral circulation （P<0.05）. In the group with collateral circulation, the scores for age, AHI, and NIHSS in the good collateral circulation subgroup were significantly lower than those in the poor collateral circulation and moderate collateral circulation subgroups, while the scores for NO, MoCA, and MMSE were significantly higher in the good collateral circulation subgroup. Multi-factor analysis revealed that age, AHI, and NIHSS were independent risk factors for collateral circulation, whereas NO, MoCA, and MMSE served as protective factors that were negatively correlated with collateral circulation. Classification tree model results indicated that AHI had the greatest influence on the occurrence of collateral circulation among the five influencing factors, demonstrating good predictive capability. Conclusion:Most high-risk patients with sleep apnea and stroke are likely to develop collateral circulation following continuous positive airway pressure ventilation. Factors such as age, AHI, NIHSS, NO, MoCA, and MMSE are important determinants affecting the occurrence of collateral circulation.

Objective:To explore the efficacy and safety of domestic bortezomib in combination with lenalidomide and dexamethasone in the treatment of newly diagnosed multiple myeloma (NDMM) .Methods:This multicenter, prospective, single-arm clinical study included 126 patients with NDMM admitted to seven hospitals between December 2019 and January 2022. All patients received domestic bortezomib in combination with lenalidomide and dexamethasone (BLD regimen), and the efficacy, prognostic factors, and safety were analyzed.Results:Among the 126 patients with NDMM, 118 completed four cycles of treatment, with an overall response rate (ORR) of 93.22% (110/118) and a ≥very good partial response (VGPR) rate of 68.64% (81/118). Ultimately, 114 patients completed at least eight cycles of treatment, with an ORR of 92.98% (106/114) and a ≥VGPR rate of 77.19% (88/114). Eighteen patients underwent autologous hematopoietic stem cell transplantation after completing 6-8 cycles of the BLD regimen, with an ORR of 100% (18/18) and a ≥VGPR rate of 88.9% (16/18). The proportion of patients achieving ≥VGPR increased with the treatment duration, and factors such as staging and age did not significantly affect efficacy. Single-factor analysis showed that R2-ISS stage Ⅲ/Ⅳ, blood calcium >2.27 mmol/L, and failure to achieve VGPR after six cycles were adverse prognostic factors for progression-free survival (PFS) ( P<0.05), whereas failure to achieve VGPR after six cycles was an adverse prognostic factor for overall survival (OS) ( P<0.001). Multifactor analysis demonstrated that failure to achieve VGPR after six cycles is an independent adverse prognostic factor for PFS ( P=0.002). The incidence of hematologic adverse reactions was 16.7% (19/114), and nonhematologic adverse reactions were mainly mild to moderate, with no significant cardiac or renal adverse reactions observed. Conclusion:The BLD regimen is effective in treating NDMM, in which patients with high-risk genetic features are still achieving a high ≥VGPR rate, and the overall safety is good.

ObjectiveTo explore the effect of Tanreqing injection combined with Ceftazide on the clinical efficacy， lung function， and laboratory inflammatory index of patients suffering from phlegm heat obstructing lung syndrome in acute exacerbation of chronic obstructive pulmonary disease （AECOPD）. MethodFrom June 2021 to June 2023， 76 patients diagnosed with phlegm heat obstructing lung syndrome in AECOPD were enrolled in the respiratory and critical medical department of Jieshou Hospital of Traditional Chinese Medicine. They were randomly divided into a control group and an observation group with 38 cases each. The control group used Ceftazidime intravenous drip and other conventional oxygen inhalation and antispasmodic treatment measures of western medicine. The observation group received Tanreqing injection intravenous drip based on the treatment of the control group， with a course of 10 days. The changes of laboratory indicators such as hs-CRP， calcitonin （PCT）， and interleukin-6 （IL-6） before and after treatment were analyzed， and the improvement of forced expiratory volume in the first second （FEV₁）， forced vital capacity （FVC）， one second rate （FEV₁/FVC）， assessment and improvement of the British Medical Research Society’s dyspnea index （mMRC）， self-evaluation test of chronic obstructive pulmonary disease patients （CAT）， and traditional Chinese medicine syndrome score was compared. In addition， the total effective rate between the two groups after treatment was compared. ResultAfter treatment， the hs-CRP， PCT， IL-6， FEV₁， FVC， FEV₁/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation of both groups improved （P<0.01）. After treatment， compared with the control group， the observation group showed more significant improvements in hs-CRP， PCT， IL-6， FEV₁， FVC， FEV₁/FVC， mMRC， CAT scores， and traditional Chinese medicine syndrome evaluation， and the difference was statistically significant （P<0.05，P<0.01）. The total clinical effective rate of the control group was 86.84% （33/38）， while that of the observation group was 94.74% （36/38）. The therapeutic effect of the observation group was better than that of the control group （χ²=8.471， P<0.05）. ConclusionTanreqing injection combined with Ceftazidime has obvious efficacy in the treatment of phlegm heat obstructing lung syndrome in AECOPD， which is better than the treatment of Ceftazidime antibiotics alone. It can reduce the risk of acute exacerbation， alleviate clinical symptoms， and delay the decline of lung function.

BACKGROUND:Some studies have found that local application of alendronate can promote osteogenesis,but less is reported on the process of distraction osteogenesis. OBJECTIVE:To observe the promoting effect of alendronate on rapid mandibular distraction in a rabbit model and explore its possible mechanism. METHODS:Thirty-six male New Zealand white rabbits were randomly divided into groups A,B and C(n=12 per group)after operation and rapid distraction(3-day delay period followed by 3-day distraction at 1.5 mm/12 hours).At the 1st,3rd and 7th days of the consolidation period,animal were injected with 200 μg/kg alendronate in group A and 100 μg/kg alendronate in group B,while those in group C were treated as controls.CT scanning and dual energy X-ray bone mineral density measurement were performed at 4 and 8 weeks of the consolidation period.After the radionuclide scanning was completed at the 4th week,several animals were sacrificed and the samples were collected for western blot assay and tartrate resistant acid phosphatase staining.A three-point bending test was performed after the animals were sacrificed at the 8th week. RESULTS AND CONCLUSION:CT results showed that bone formation in the distraction space of group B was significantly better than that in groups A and C.At the 4th week,the bone mineral density in group B was(0.092±0.010)g/cm2,which was 1.26 times higher than that in group A(P＜0.001)and 1.28 times higher than that in group C(P＜0.001).At the 8th week,the bone mineral density in group B was(0.175±0.029)g/cm2,which was 1.38 times higher than that in group A(P＜0.001)and 1.45 times higher than that in group C(P＜0.001).Tartrate resistant acid phosphatase staining showed that the number of osteoclast-like cells in group C were 2.83 times more than that in group A(P＜0.001)and 2.21 times more than that in group B(P＜0.001).The radionuclide intensity was higher in group C than in groups A and B.Western blot assay results showed that the expression of Runx2 was significantly stronger in group B than in groups A and C.The maximum biomechanical load in group B was(158.48±23.21)N,which was 1.26 times higher than that in group A(P=0.007)and 1.31 times higher than that in group C(P=0.003).To conclude,the low concentration of alendronate may promote rapid distraction osteogenesis of the rabbit mandible by inhibiting osteoclast signals.

Objective To construct and apply an intelligent follow-up information system for patients with cancer pain,providing references for improving the efficiency of hospital follow-up and promoting pain management of patients at home.Methods The intelligent discharge follow-up system for patients with cancer pain includes 2 platforms,namely a patient self-report platform and an administrator operation platform.The administrator operation platform consists of 5 modules,namely the workbench module,the follow-up plan module,the follow-up results module,the health education module and the data statistics module.In January 2022,the system was officially put into clinical application.The use of the system was analyzed,and patients'completion rate,medication compliance,incidence of moderate and severe pain and satisfaction with pain control were compared before(from January 2020 to December 2021)and after(from January 2022 to November 2023)the application of the system.Results At present,this system has been applied in 95 cancer-related wards of our hospital.From January 2022 to November 2023,the number of people who should be followed up was 4 248,and the number of people who actually completed the follow-up was 4 127;the rate of follow-up completion was 97.2%;the rate of timely completion of the follow-up was 94.9%;the rate of automatic follow-up by the system was 40.1%;the rate of patient abnormality report was 31.9%;the rate of timely treatment of patient abnormality report was 89.1%.After the application of the system,the completion rate of pain follow-up was increased,and the difference was statistically significant(P<0.001).After the application of the system,the medication compliance rate of patients with cancer pain increased from 86.9%to 91.0%;the incidence of moderate and severe pain decreased from 6.8%to 5.2%;the satisfaction with pain control increased from 81.0%to 83.5%(P<0.05).Conclusion The intelligent discharge follow-up system for patients with cancer pain can effectively improve the discharge follow-up efficiency and promote the management of patients with cancer pain at home.

Objective Changes in relevant indexes in the mouse model of early-onset ovarian insufficiency caused by Tripterygium wilfordii polyglycoside were analyzed,and the optimal time point for intervention was determined.Methods Forty female ICR mice were randomly divided into control and A,B,C,and D model groups with eight mice in each group.The control group was gavaged with purified water for 14 days(0.01 mL/10 g),and the remaining groups were administered a Tripterygium wilfordii polyglycoside suspension(80 mg/kg,0.01 mL/10 g)for 1 day(A model group),3 days(B model group),7 days(C model group),or 14 days(D model group),and samples were collected.Body weight and wet weights of the uterus and bilateral ovaries of mice were determined in each group.Serum FSH,LH,E2,P,AMH,INH-B,and T contents were measured using enzyme-linked immunoassays.HE staining was used to observe the number and developmental status of follicles and corpus luteum at all levels in mice of each group.TUNEL staining was used to detect the apoptosis in the ovaries of mice in each group.IHC detected expression of VEGFA,CD34,and EPO proteins in the ovaries of mice in each group.mRNA expression of HIF-1α,SDF-1,and CXCR4 in each group of mice was detected by PCR.Results Compared with the control group,changes in indicators in model A mice did not meet the POI modeling standard.The ovarian index,uterine index,and body weight of mice in the B model group were decreased significantly(P＜0.01),the weight of the C model group was decreased significantly(P＜0.01),and the ovarian index of the D model group was decreased significantly(P＜0.05).Serum contents of FSH and LH in B,C,and D model groups were increased(P＜0.05,P＜0.01),the E2,PROG,AMH,INH-B,and T contents were decreased(P＜0.01).The numbers of basal follicles,pre-sinus follicles,sinusoidal follicles,antral follicles,preovulatory follicles,and corpus luteum were decreased significantly(P＜0.05,P＜0.01)and the number of atresia follicles was increased significantly(P＜0.01)in B,C,and D model groups.The apoptotic area of TUNEL staining in A,B,C,and D model groups was increased significantly(P＜0.05,P＜0.01).Expression of CD34,VEGFA,and EPO in B,C,and D model groups was decreased significantly(P＜0.05,P＜0.01).mRNA expression of HIF-1α,SDF-1,and CXCR4 in A and B model groups was significantly increased(P＜0.05,P＜0.01).Compared with the B model group,the relevant indexes of C and D model groups were changed significantly,indicating that C and D models were more serious and tended to develop POF.Conclusions The B model group is the turning point of ovarian function from impaired POI to irreversible POF,suggesting that 3 days of administrating Tripterygium wilfordii polyglycoside is optimal to induce a POI disease model for effective drug intervention.

Objective To explore the effect and predictive value of blood lactate level on bronchopulmonary dysplasia(BPD)in newborns with neonatal respiratory distress syndrome(NRDS).Methods A total of 78 children with NRDS admitted to the First People's Hospital of Pingdingshan from January 2019 to December 2022 were selected as the research subjects.Based on whether they had BPD,the children were divided into a BPD group and a non-BPD group.The general clinical data of the children,including gestational age,gender,birth weight,1-minute Apgar score,5-minute Apgar score,and premature rupture of membranes,were collected.At admission,1 mL of arterial blood was extracted from the children,and the blood lactate level,arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2),pH value,and oxygenation index(OI)were measured using a JM1113-739853 blood gas analyzer;3 mL of peripheral venous blood was extracted from the children,and the level of interleukin-6(IL-6)in the serum was detected by enzyme-linked immunosorbent assay,while the levels of C-reactive protein(CRP)and procalcitonin(PCT)in the plasma were detected by double antibody sandwich method.The general information,blood lactate levels,PaO2,PaCO2,pH value,OI,serum IL-6 levels,plasma CRP and PCT levels of children were compared between the two groups.The correlation between blood lactate levels and NRDS complicated with BPD was determined by point-biserial correlation analysis,the influencing factors of NRDS complicated with BPD was analyzed by logistic regression,and the predictive value of blood lactate levels for NRDS complicated with BPD was analyzed by receiver operating characteristic curve.Results The blood lactate levels of 78 children with RDS ranged from 3.35 to 6.64(5.04±0.72)mmol·L-1.There were 16 children with BPD,with an incidence rate of 20.51％(16/78).The birth weight and OI of children in the BPD group were significantly lower than those in the non-BPD group,while the serum IL-6,plasma CRP,and blood lactate levels were significantly higher than those in the non-BPD group(P＜0.05).There was no statistically significant difference in gestational age,gender,1-minute Apgar score,5-minute Apgar score,premature rupture of membranes,PaO2,PaCO2,pH value,and PCT of children between the two groups(P＞0.05).The point-biserial correlation analysis showed that blood lactate,serum IL-6,and plasma CRP levels were positively correlated with the risk of BPD in children with NRDS(r=0.502,0.475,0.507;P＜0.05);while birth weight and OI were negatively correlated with the risk of BPD in children with NRDS(r=-0.242,-0.403;P＜0.05).Logistic regression analysis showed that blood lactate accumulation,high expression of serum IL-6,high expression of plasma CRP,and decreased OI were risk factors for BPD in children with NRDS(P＜0.05).The area under the curve for predicting BPD in children with NRDS based on blood lactate was 0.865,with a 95％confidence interval of 0.776 to 0.955;when the cut-off value of blood lactate was 5.065 mmol·L-1,the sensitivity and specificity of predicting BPD in children with NRDS were 0.938 and 0.501,respectively.Conclusion There is a positive correlation between blood lactate levels and the risk of BPD in children with NRDS.Blood lactate accumulation is a risk factor for NRDS complicated with BPD,and blood lactate level has a certain predictive value for NRDS complicated with BPD.

Objective To investigate the clinicopathological factors associated with pathological complete response(pCR)of axillary metastatic lymph nodes in breast cancer patients after neoadjuvant chemotherapy(NAC),and to analyze the postoperative survival.Methods A total of 116 patients with breast cancer with axillary lymph node metastasis were collected from Jiaxing Hospital of TCM,Jiaxing Maternity and Child Health Care Hospital and The First Hospital of Jiaxing.Univariate analysis was used to analyze the relationship between clinicopathological factors and the pCR of axillary lymph node metastasis in breast cancer after NAC.Binary Logistic regression was used to analyze the independent predictors of the pCR of axillary lymph node metastasis in breast cancer after NAC.Kaplan-Meier survival curve was used to analyze the disease-free survival rate and overall survival rate of patients with and non-pCR of axillary metastatic lymph nodes.Results Among 116 patients,52 cases of axillary metastatic lymph nodes achieved pCR after NAC,accounting for 44.83%.Univariate analysis showed that age,vascular invasion,pCR of primary breast tumor,the difference of Ki67 before and after NAC,NAC regimen,and the efficacy of NAC were statistically significant between breast cancer patients with pCR and those non-pCR(P<0.05).Binary Logistic regression analysis showed that age,vascular invasion and pCR of primary breast tumor were independent predictors of pCR of axillary metastatic lymph nodes(P<0.05).The 5-year disease-free survival rate(80.40%vs.54.60%)and overall survival rate(90.4%vs.70.10%)of patients with pCR and non-pCR of axillary metastatic lymph nodes were compared.Conclusion Some breast cancer patients with axillary lymph node metastasis can reach pCR in lymph nodes after NAC.Analyzing the correlation between clinical pathological factors and pCR of axillary metastatic lymph nodes after NAC,it was found that pCR of axillary metastatic lymph nodes after NAC is related to age≤50 years old,no vascular infiltration,and primary breast tumor pCR.At the same time,it was found that patients with axillary metastatic lymph node pCR had a better prognosis than those with non-pCR.

Objective: To explore the changes in root volume and root resorption in incisor arteries from adult patients with skeletal class Ⅲ malocclusion before and after camouflaged orthodontic treatment and to provide a reference for the clinic. Methods : Thirty permanent dentition adult patients with skeletal class Ⅲ malocclusion were included from the Orthodontic Department. CBCT data of each patient at pretreatment and posttreatment were acquired, and 3D digital root models were reconstructed. The whole and segmented root volumes (cervical part, bodily part and apical part) of the right incisors were calculated. Results: The root volumes (whole, cervical part, bodily part and apical part) posttreatment were smaller than those pretreatment (P<0.001). Maxillary central incisors and lateral incisors showed similar resorption in the cervical root and bodily root and more changes in the apical root, but there was no significant difference (P>0.05). Mandibular central incisors and lateral incisors showed more root resorption in the apical root than in the cervical root and bodily root (P<0.01). The absorption ratio of all segmented roots in each incisor showed a significant difference (P<0.001), and apical absorption was the most obvious. There were no significant differences in root volume change amounts or the absorption ratio of the whole, cervical part and bodily part in all incisors (P>0.05). The absorption ratio showed a significant difference in the mandibular lateral incisors (P = 0.028). Conclusion After camouflaged orthodontic treatment of adult skeletal class Ⅲ malocclusion, incisor root resorption occurred mainly in the apical part, but the cervical and bodily parts should also be considered. There was a high risk of root resorption in the mandibular incisors.
