ABSTRACT
Objective:To explore the clinical efficacy of sinew-regulating and bone-setting manipulation combined with functional exercise to treat mild to moderate rotator cuff injury (RCI).Methods:Forty patients with mild to moderate RCI were randomly divided into a treatment group and a control group,with 20 cases in each group.The treatment group was given sinew-regulating and bone-setting manipulation combined with functional exercise,and the control group was given the same manipulation as the treatment group.The therapeutic effect on the functional improvement was assessed after treatment according to pain threshold,shoulder range of motion (ROM) including flexion,abduction,internal rotation and external rotation,and the University of California at Los Angeles (UCLA) shoulder rating score.Results:Compared with the same group before treatment,the pain threshold,shoulder flexion,abduction,internal and external rotations increased after the treatment in the two groups (all P＜0.05).The UCLA shoulder rating score increased (both P＜0.05).The improvement in the treatment group is significantly better than that in the control group with a statistical significance (P＜0.05).The total effective rate was 95.0％ in the treatment group,was higher than 65.0％ in the control group (P＜0.05).Conclusion:The sinew-regulating and bone-setting manipulation combined with functional exercise relieve the pain of patients with mild to moderate RCI,increase the motion of shoulder joints,and improve the quality of life of patients.The curative effect is better than the treatment of simple sinew-regulating and bone-setting manipulation.
ABSTRACT
Objective:To observe the effect of electroacupuncture (EA) at Jiaji (EX-B 2) points plus hydro-acupuncture with sinomenine hydrochloride for low back pain caused by compression fractures in the elderly.Methods:Ninety-five elderly in-patients with low back pain caused by compression fractures were randomly divided into an observation group and an EA group according to the visit sequence.Both groups received the same basic treatment.In the EA group,48 cases were treated with EA at Jiaji (EX-B 2) points plus the basic therapy;47 cases in the observation group received the basic treatment plus EA and hydro-acupuncture with sinomenine hydroch｜oride at Jiaji (EX-B 2) points.The levels of osteoprotegerin (OPG) and interleukin-1β (IL-1β) in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA) before and at the 21st day of treatment in both groups.Oswestry disability index (ODI) and visual analog scale (VAS) scores were used to analyze the clinical efficacy.Results:After treatment,the OPG content in the observation group was higher with statistical significance compared with that before treatment in the observation group and after the treatment in the EA group,respectively (both P＜0.05);the content of IL-1β,ODI and VAS scores were lower than those before treatment in the observation group and after treatment in the EA group with statistical significances (all P＜0.05).Conclusion:The combination of EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji (EX-B 2) points is effective for low back pain caused by compression fractures in the elderly,and is superior to EA at Jiaji (EX-B 2) points alone.
ABSTRACT
Objective:To observe the curative effect of cervical chiropractic for cervical spondylosis of vertebral artery type (CSA) and to explore its possible mechanism.Methods:Sixty CSA patients were randomly divided into two groups.Thirty patients in the treatment group were treated with chiropractic manipulation for cervical vertebrae,once every other day,7 treatments in total.The other 30 patients in the control group received oral administration of flunarizine hydrochloride,10 mg per night,for 14 d.Cervical vertigo and functional assessment scale and transcranial cerebral Doppler (TCD) were measured before treatment and 7 days after treatment.Results:The total effective rate was 96.7％ in the treatment group and 83.3％ in the control group.The curative rate was 66.7％ in the treatment group and 20％ in the control group.The differences between the two groups in the total effective rate and the curative rate were statistically significant (both P＜0.05).The scores of cervical vertigo symptom and functional assessment after treatment in both groups were significantly higher than those before treatment (both P＜0.01);the difference between the two groups was statistically significant (P＜0.05).After treatment,the maximum systolic velocity (Vs),the maximum diastolic velocity (Vd),the mean velocity (Vm),the pulsatility index (PI) and the vascular resistance index (RI) in both groups were significantly improved compared with those before the treatment (all P＜0.01);there were significant differences between the two groups (all P＜0.05).Conclusion:Cervical chiropractic is an effective method for CSA,and its curative effect is better than that of flunarizine hydrochloride alone.Its mechanism may relate to correcting cervical instability.
ABSTRACT
Mesenchymal stem cells (MSCs) could be obtained from many sources, and there are differences between them. This study was purposed to compare and analyze the basic biological characteristics of umbilical cord, adipose tissue-and bone marrow-derived MSC (UC-MSCs, AD-MSCs and BM-MSCs). The MSCs were isolated from umbilical cord, adipose tissue and bone marrow were cultured; the morphology of UC-MSCs, AD-MSCs and BM-MSCs was observed by using microscopy; the immunophenotype, differentiation potential and expression of peroxisome proliferation-activated receptor-γ (PPAR-γ) mRNA were detected by using flow cytometry, differentiation test (von kossais and 0:1 red O staining) and quantitative fluorescent PCR, respectively. The results showed that the UC-MSCs, AD-MSCs and BM-MSCs displayed similar morphology under confocal microscope after being stained with rhodamine phalloidin and DAPL. The immunophenotypes of these three originated cells conform to coincide with identification criterion for MSCs, and showed similar expression level. During adipogenic induction the adipogenic potential of these MSCs was different, AD-MSCs exhibited the highest adipogenic potential, UC-MSCs displayed the lowest, while potential of BM-MSCs get between; however, the osteogenic differentiation potential of UC-MSCs, AD-MSCs and BM-MSCs was similar. The PCR detection showed that the expression level of PPAR-γ mRNA was the highest in AD-MSCs and the lowest in UC-MSCs, while expression level in BM-MSCs get between, these results were identical with the adipogenic potential, suggest that the difference of adipogenic potential in 3 kinds of MSCs was associated with basic expression level of PPAR-γ mRNA. It is concluded that UC-MSCs, AD-MSCs and BM-MSCs exhibit similar morphology, the immunophenotypes of these MSCs coincide with identification criterion for MSCs, the osteogenic potential of these MSCs is similar, while the adipogenic potential and the expression level of PPAR-γ mRNA are different. The difference-associated mechanisms need to further study.

The purpose of this study was to investigate the expression of human Factor IX (hFIX) in retrovirus-transfected human umbilical cord tissue derived mesenchymal stem cells (hUCT-MSCs). The pLEGFP-N1-hFIX vector was generated by cloning a 3.0 kb Bgl II-BamH I fragment from the pIRES2-EGFP-hFIX plasmid containing the hFIX cDNA and part of intron 1 of hFIX in pLEGFP-N1 vector. The retroviral supernatants were produced from the Phoenix packaging cell line and then infected the hUCT-MSCs. After selection with G418 for 10 day, the expression of FIX was detected by ELISA and Western blot. The biological activity of FIX was determined by the clotting assay employing human Factor IX-deficient plasma. The results showed that compared with the activity of pooled human normal plasma (100%), transduced cells produced biologically active hFIX with 100-130% activity in two-day culture supernatant and expressed hFIX at levels of 2.68 +/- 0.36 microg/10(6) cells/24 hours after G418 selection for 10 days. The secretion of hFIX into culture supernatant was also confirmed by Western blot analysis. It is concluded that genetically modified hUCT-MSCs can express biologically active hFIX and thus serve as an efficient drug delivery vehicle carrying hFIX used as a way of somatic gene therapy for hemophilia B.
