Objective Under the guidance of meridian-sinew(jingjin)theory,the correlation between foot-yangming jingjin lesions and X-ray imaging findings such as medial space and lateral space in femorotibial joint and their ratio,degree of subluxation of femorotibial joint,and the Insll-Salvati index in the patients with knee osteoarthritis(KOA).Methods From January 2019 to November 2021,a total of 66 patients diagnosed as KOA at the Third Affiliated Hospital of Guangzhou University of Chinese Medicine were selected as the study subjects.The patients were divided into the foot-yangming jingjin group and non-foot-yangming jingjin group according to the presence of foot-yangming jingjin lesions.The X-ray postero-anterior and lateral radiography of the knee joint under weight bearing was performed,and imaging parameters of the two groups were measured.Afterwards the pain Visual Analogue Scale(VAS)scores and Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)scores in the two groups were evaluated,the differences between the two groups'X-ray imaging findings and scale scores were compared,and the various X-ray imaging findings in the two groups were analyzed.Results(1)Under X-ray postero-anterior radiography of the knee joint,the medial space and lateral space in femorotibial joint and their ratio in non-foot-yangming jingjin group were lower than those in foot-yangming jingjin group,and degree of subluxation of femoro-tibial joint was higher than that of foot-yangming jingjin group(P<0.05 or P<0.01).(2)The ratio of length of patellar tendon to length of patella(LT:LP)under X-ray lateral radiography in foot-yangming jingjin group was significantly greater than that of the non-foot-yangming jingjin group(P<0.01).(3)The scores of pain VAS and WOMAC in non-foot-yangming jingjin group were both significantly higher than those in foot-yangming jingjin group(P<0.05),while the differences of the scores of WOMAC items such as joint stiffness and physiologic function,and the total WOMAC scores between the two groups were not statistically significant(P>0.05).Conclusion Foot-yangming jingjin lesions in KOA may be closely related to the relatively high position of patella under X-ray lateral radiography,and non-foot-yangming jingjin lesions may be closely related to the narrowing of the medial femorotibial joint space,the increase of medial-lateral space ratio,and the severity of subluxation under X-ray postero-anterior radiography.

Objective:To explore the effect of pulmonary rehabilitation program based on Delphi method in patients with overlap syndrome (OS) .Methods:From March 2019 to March 2021, a total of 107 OS patients admitted to Qinghai Provincial People's Hospital were enrolled using the convenience sampling method and divided into the observation group ( n=54) and the control group ( n=53) by the random number table method. The control group received conventional nursing, and the observation group conducted pulmonary rehabilitation program based on Delphi method on the basis of conventional nursing. The COPD Assessment Test (CAT) , the 6-Minute Walk Test (6MWT) , and the St George's Respiratory Questionnaire (SGRQ) were used to assess the improvement of the conditions, exercise endurance, and quality of life of the two groups before and after intervention. Results:After intervention, the CAT score of the observation group was lower than that of the control group, 6MWD was longer than that of the control group, and the clinical symptoms, disease impact, and activity scores of SGRQ were lower than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The pulmonary rehabilitation program based on the Delphi method can reduce patients' condition, improve exercise endurance and quality of life.

OBJECTIVETo evaluate the clinical characteristics and prognostic factors of patients with primary gastro-intestinal marginal zone lymphoma (MALT).

METHODSRetrospective analysis was performed in 90 patients diagnosed with primary gastro-intestinal MALT lymphoma clinical characteristics and survival analyses.

RESULTSAmong 90 patients, 78 cases were originated from the stomach and 12 cases with extra-gastric origin. Eighty patients were classified as low-risk (IPI score 0-2), and 10 patients high-risk (IPI score 3-5). Compared to gastric MALT patients, extra-gastric cases presented with higher IPI score (7.7% vs 33.3%, P=0.025) and higher Hp infection rate (50.0% vs 87.2%, P<0.01). Treatment options for low risk patients (IPI score 0-2) included Hp eradication, surgery, radiotherapy and chemotherapy. Chemotherapy could improve progression-free survival (PFS) in low-risk patients. For high-risk patients, those receiving chemotherapy had 100% 3-year overall survival (OS). Univariate analysis revealed that ECOG (P=0.006), Mussh-off staging (P=0.008), IPI score (P=0.000), elevated LDH (P=0.019) and chemotherapy (P=0.026) were correlated with PFS. Multivariate analysis showed that higher IPI score (IPI 3-5) (OR=8.325, 95% CI 3.171-21.853, P=0.000) and chemotherapy (OR=0.319, 95% CI 0.121-0.838, P=0.020) were independent prognostic factors for PFS. ECOG (≥ 2) was independent prognostic factor for OS (OR=5.092, 95%CI 1.005-25.788, P=0.049).

CONCLUSIONPrimary gastro-intestinal MALT lymphoma was an indolent subtype of non-Hodgkin's lymphoma. Patients usually had low risk IPI and achieved long-term survival. Frontline therapy for low-risk patients was radiotherapy or Hp eradication, and chemotherapy for high-risk ones.

In the canonical version of evolution by gene duplication,one copy is kept unaltered while the other is free to evolve.This process of evolutionary experimentation can persist for millions of years.Since it is so short lived in comparison to the lifetime of the core genes that make up the majority of most genomes,a substantial fraction of the genome and the transcriptome may-in principle-be attributable to what we will refer to as "evolutionarytransients",referring here to both the process and the genes that have gone or are undergoing this process.Using the rice gene set as a test case,we argue that this phenomenon goes a long way towards explaining why there are so many more rice genes than Arabidopsis genes,and why most excess rice genes show low similarity to eudicots.

Objective. The aim of this study was to detect coronary artery disease using99m Tc-MIBI myocardial perfusion imaging in patients with valvular disease.Methods. Thirty patients with valvular disease confirmed by echocardiography underwent 99mTc-MIBI myocardial perfusion imaging using multiSPECT 1h after stress test (exercise, dipyridamole or dobutamine test) and were performed coronary angiography within 1 month before valvular operation.Results.For 29 out of the 30 patients, the results of 99mTc-MIBI myocardial perfusion imaging were similar with those of coronary angiography, the concordance rate was 96.7% and the negative predictability was 100%.Conclusion.99m Tc-MIBI myocardial perfusion imaging is a reliable non-invasive method for detecting coronary artery disease in patients with valvular disease and so as to draw up suitable operation programs for them.

AIM: To study the effects of acute HIV-1 infection on gene expression in U937 human promonocyte for understanding the pathogenecis of AIDS. METHODS: The expression levels of 550 host cell RNA transcripts in U937 human promonocyte at 2-3 d after HIV-1 infection were assessed using cDNA microarray analysis, and the results were confirmed by semiquantitative RT-PCR. RESULTS: Our results showed that 38 genes were differentially regulated in the infected U937 cells at 2-3 d post infection: 26 genes were down-regulated and 12 genes were up-regulated. These genes encode a host of proteins with divergent functions in a variety of cellular processes including receptor-mediated signaling transduction, subcellular signal trafficking, apoptosis, transcriptional regulation, and chemotaxis. CONCLUSION: HIV-1 infection alters gene expression in U937 human promonocytes.
