ABSTRACT
Objective: To expore the correlation between neck disability, neck pain and muscle strength in cervical pondylosis of office worker, and to provide scientific basis for the prevention and treatment of cervical spondylosis. Methods: In April 2021 ,234 patients with cervical spondylotic myelopathy treated in the Subsidiary Rehabilitation Hospital of Fujian University of Traditional Chinese Medicine from April 2015 to April 2017 were selected, the correlation between Neck Disability Index (NDI) score, neck pain and muscle strength was analyzed using the Spearman rank correlation method. Mann-Whitney U test was used to compare the difference of maximum muscle strength of isometric contraction. Results: NDI score was negatively correlated with neck flexion, extension, and muscle strength in the left and right flexion directions (r(s)=-0.164, -0.169, -0.222, -0.176, P=0.012, 0.010, 0.001 , 0.007). In mild and moderate functional disorder patients, the muscle strength in flexion, extension and left and right flexion direction was greater, the difference was statistically significant (P <0.01). Conclusion: There is a negative correlation between cervical functional disorder and cervical muscle strength in office workers, suggesting that strengthening cervical muscle strength may be a way to improve cervical spine function.

OBJECTIVE@#To determine the effects of Chinese medicine (CM) involving triple rehabilitation therapy on the progression of knee osteoarthritis (KOA).@*METHODS@#A total of 722 patients recruited from 38 community health service centers located in China from March 2013 to March 2017 were randomly divided into treatment and control groups equally, using a cluster randomization design. Health education combined with CM involving triple rehabilitation therapy for KOA (electro-acupuncture, Chinese medicinal herb fumigating-washing, and traditional exercises) was administered in the treatment group while conventional rehabilitation therapy (physical factor therapy, joint movement training, and muscle strength training) was administered in the control group. Patients with a visual analog scale (VAS) scores ≽4 were treated with dispersible meloxicam tablets (7.5 mg, once daily). The Lequesne index scores, VAS scores, range of motion (ROM), lower limb muscle strength, knee joint circumference, quantitative scores of KOA symptoms, and the short-form 36 item health survey questionnaire (SF-36) scores were measured for each patient at 5 checkpoints (before treatment, at the 2nd week and the 4th week during the 4-week treatment period, at 1 month and 3 months after end of treatment), and adverse reactions were observed also.@*RESULTS@#A total of 696 patients completed the entire process, with 351 in the treatment group and 345 in the control group. At all treatment checkpoints, the treatment group demonstrated better outcomes than the control group with regard to the total Lequesne index scores, effective rate and improvement rate of the total Lequesne index scores, VAS scores, lower limb muscle strength, knee circumference, quantitative scores of KOA symptoms, and SF-36 scores as well (P<0.05 or P<0.01). No adverse reactions were encountered in this study.@*CONCLUSIONS@#CM involving triple rehabilitation therapy can alleviate KOA-related pain and swelling, improve lower limb muscle strength, promote flexion and activity of the knee and improve the quality of life in patients undergoing KOA. It is suitable for patients with early or mid-stage KOA. (Registration No. ChiCTR-TRC-12002538).

<p><b>OBJECTIVE</b>To observe the effect of Guizhi plus Gegen Decoction (GGD) on ultrastructural changes of intervertebral disc annulus fibrosus cells.</p><p><b>METHODS</b>Rats' intervertebral disc annulus fibrosus cells were isolated and cultured using adherence wall screening method. After annulus fibrosus cells were intervened by GGD, the microstructure and ultrastructural features of untreated annulus fibrosus cells and annulus fibrosus cells treated by GGD containing serum at different concentrations were observed under optical microscope and electron microscope.</p><p><b>RESULTS</b>Under optical microscope, most annulus fibrosus cells showed irregular polygons and few in star shape with rich superficial ecphyma. The nuclei were oval, large and complete. Under electron microscope, most cells in the blank group were oval after intervened by GGD containing serum at different concentrations. The nucleus was large, deviated, and irregular, the heterochromatin scattered diffusely, partial mitochondria vacuolized, and rough endoplasmic reticulum dilated. In the low dose GGD group, increased mitochondria and condensed density could be seen. The rough endoplasmic reticulum were expanded, lipid drops or glycogen could be occasionally seen. In the middle dose GGD group, increased endoplasmic reticulum expansion and condensed density could be seen. More medium density protein sediment could be seen. Increased mitochondria with condensed density could be seen, showing irregular cystic form with various sizes nucleus. In the high dose GGD group, increased rough endoplasmic reticulum with obvious expansion could be seen. More high density protein sediment could be seen. The nuclei were deviated. More mitochondria could be seen with secretory granules in them.</p><p><b>CONCLUSIONS</b>After intervened by GGD containing serum at different concentrations, the ultrastructure of annulus fibrosus cells were manifested as follows: (1) The endoplasmic reticulum increased more in the middle and high dose GGD groups than in the blank group and the low dose GGD group. Greater density protein sediment occurred, especially in the high dose GGD group. (2) GGD played an important role in preventing ultrastructural changes induced by the degeneration of annulus fibrosus cells.</p>

Objective Under different standard uptake value(SUV),to assess gross tumor volume (GTV) definition for non-small cell lung cancer(NSCLC) with 18-fluoro-deoxy-glucose positron emission tomography (~(18)FDG PET) both under definite threshold (42 percent threshold) and various relative threshold (threshold SUV/maximum SUV) derived from the linear regressive function,threshold SUV=0.307?(mean target SUV)+0.588,with computer tomography (CT).Methods Of 20 patients with non-small cell lung cancer,the CT GTV (GTV_(?)).PET GTV with 42 percents threshold (GTV_(42%)) and PET GTV with relative threshold (GTV_(?)) were obtained and compared.Results The mean GTV_(42%),,mean GTV_(?) and mean GTV_(CT) was (13 812.5?13 841.4),(24 325.3?22 454.7) and (28 350.9?26 079.8)mm~3,respectively,with the difference in mean GTV among these three methods significant (F =10,P＜0.01).The GTV_(42%) was smaller than the GTV_(?) and the GTV_(CT)(P＜0.01),with i(?)significant difference between GTV_(?) and GTV_(CT)(P=0.125).Conclusion The relative threshold is more suitable to define the gross tumor volume than the definite threshold.
ABSTRACT
Objective To assess the value of 18-fluoro-deoxy-glucose positron emission-CT(FDG PET-CT) in defining the length of primary esophageal cancer.Methods Thirty-two patients had underg- one esophagoscopy,esophagography and FDG PET-CT scans one week before esophagectomy.There was one tumor located in the upper thoracic esophagus,22 in the middle thoracic esophagus,and 9 in the lower tho- racic esophagus.The location and length of primary lesion of the tumor was determined by esophagoscopy, esophagography,and FDG PET-CT.The length of the abnormality seen on the CT portion of the PET-CT scan was determined separately and independently by two radiologists.All results were compared with the resected specimen.Results According to esophagography,CT and PET-CT,all lesion lengths were compared with that of the resected specimen.It was found that the tumor location determined by esophagoscopy was not in accordance with the resected specimen in 2 patients.The mean length of the primary tumor,being from short to long,were (3.8?1.4),(4.1?1.5),(4.4?1.6),(5.3?1.9) and (4.7?1.7) cm,as determined by esophagoscopy,esophagography,CT,actral length of the resected specimen and PET-CT.Compared with the resected specimen,there was obvious difference (P=0.000,0.007,0.025,0.001).Considering that there might be some kind of shrinkage in the resected specimen (about 83.59%,as reported by Ma et al), we rectified the length of resected specimen and compared with other findings again.It was found that insig- nificant difference existed between PET-CT and rectified length value of the resected specimen (P=0.082). Conclusions FDG PET-CT is effective in the length determination of primary esophageal cancer.It may he used to determine the length of esophagus to be resected for patients indicated for esophagectomy.It may also be used to ac- curately delineate the gross tumor volume for patients eligible for radiotherapy.
