Objective To observe the clinical efficacy of electroacupuncture at different frequencies in treating post-stroke depression. Methods A hundred patients with post-stroke depression were randomized into treatment group 1, treatment group 2, treatment group 3, and a control group, 25 in each group. The treatment groups were intervened by electroacupuncture, while 2 Hz was adopted in treatment group 1, 50 Hz in treatment group 2, and 100 Hz in treatment group 3. The control group was intervened by oral administration of Sertraline Hydrochloride tablets. The Function Independent Measure (FIM) and Hamilton Depression (HAMD) scale were adopted for observation before and after intervention, and the clinical efficacies were compared. Results The FIM and HAMD scores were significantly changed after intervention in the four groups (P<0.05). After treatment, the FIM and HAMD scores in treatment group 1 were significantly different from that in treatment group 2 and 3 (P<0.05). The FIM score in treatment group 1 was significantly different from that in the control group (P<0.05). The total effective rate was 96.0%in treatment group 1, versus 92.0%in treatment group 2, 82.0%in treatment group 3, and 84.0%in the control group. The total effective rate in treatment group 1 was significantly different from that in the control group (P<0.05). Conclusions Electroacupuncture at 2 Hz, 50 Hz, and 100 Hz all can improve the activities of daily living and depression degree in patients with post-stroke depression, while 2 Hz ranks the top in comparing the therapeutic efficacy.

BACKGROUND:As a more common method in the orthopedic field, the method of intra-articular injection drugs has distinct curative effects, but there are some complications. In a certain extent, this method caters to the psychological fear of surgery, and can serve as a kind of conservative treatment. But some experts believed that because of the limit of sterile conditions, intra-articular injection of drugs wil increase the risk of intra-articular infection and they opposed this method.
OBJECTIVE:To review the efficacy and adverse reactions of intra-articular injection drugs in recent years, and explain clinical applications of intra-articular injection drugs in orthopedics.
METHODS:A computer-based search was conducted in PubMed and Wanfang database for articles related to the application of intra-articular injection drugs in orthopedics published between January 2007 and December 2013. The English and Chinese key words were“intra-articular, injection, orthopaedics, tranexamic acid, hyaluronic acid, corticosteroid, drugs”. Data were checked in the first trial, old articles and repetitive studies were excluded. The relevant 43 articles accorded with inclusion criteria were reviewed.
RESULTS AND CONCLUSION:In orthopedics, the method of intra-articular injection drugs is simple, economic and effective, but at the same time, there are some side effects. Tranexamic acid by intra-articular injection can significantly reduce blood loss after total joint replacement, is safety and economic. Intra-articular injection joint lubricant can reduce internal friction of joints and improve the adhesion of joint cavity, can be used as a good conservative treatment for osteoarthritis. Intra-articular injection hormone drugs can treat inflammatory arthritis, and short-term curative effect is obvious, but due to large long-term side effects, the method is not recommended now. Intra-articular injection of analgesic drugs and other drugs have both advantages complications. The efficacy of intra-articular injection drugs in orthopedics is obvious;meanwhile, this method has some complications. Orthopedic surgeons should select related drugs by indications. We stil need to further make reasonable regimen with intra-articular injection drugs in future large-scale study.

OBJECTIVETo observe the effects on post-stroke depression treated with acupuncture at the acu points based on ziwuliuzhu (the midnight-noon ebb-flow theory).
METHODSNinety-three patients were randomized into a comprehensive group, a ziwuliuzhu group and a prozac group, 31 cases in each group. In the ziwuliuzhu group, acupuncture was applied to the acupoints based on ziwuliuzhu, once a day, 5 times in a week. In the prozac group, fluoxertine hydrochloride (prozac) was prescribed for oral administration, once a day, 20 mg each time. In the comprehensive group, acupuncture based on ziwuliuzhu combined with the oral administration of prozac were adopted and the treatment frequency was the same as the ziwuliuzhu group and the prozac group. The 4-week treatment was taken as one session in the three groups and 6 sessions were required totally. The clinical efficacy and the Hamilton depression rating scale (HAMD) score and the adverse reaction were compared among the 3 groups.
RESULTSThe total effective rate was 96.8% (30/31) in the comprehensive group, better than 83.9% (26/31) in the ziwuliuzhu group and 80. 6% (25/31) in the prozac group (both P<0.05). In 4, 12 and 24 weeks of treatment, HAMD score was lower significantly than that before the treatment in the three groups (all P<0.05), and the score in the comprehensive group at each time point after treatment was lower than the other two groups (all P<0.05). In 4 and 12 weeks of treatment, there were not different significantly between the ziwuliuzhu group and the prozac group (both P>0.05). In 24 weeks of treatment, HAMD score in the ziwuliuzhu group was lower than that in the prozac group (P<0.05). For the adverse reaction, there were 2 cases in the comprehensive group, 6 cases in the prozac group and 0 case in the ziwzuliuzhu group.
CONCLUSIONThe comprehensive therapy of acupuncture at the acupoints based on ziwuliuzhu and oral administration of prozac is superior to either the simple oral administration of prozac or the ziwuliuzhu acu-puncture in terms of clinical efficacy and the improvements in depressive state. Regarding the clinical efficacy, the impact of simple ziwuliuzhu acupuncture is not different significantly as compared with the simple oral administration of prozac, but it is better than the simple oral administration of prozac in terms of the long-term HAMD score and safety.

BACKGROUND:Tranexamic acid has been more and more used in reducing bleeding after joint replacement, but its usage method and dosage remain controversial, and become a hot focus in recent years. OBJECTIVE:To investigate the efficacy of intra-articular injection of tranexamic acid on postoperative blood loss and limb circumference changes in patients who received unilateral total knee arthroplasty. METHODS:From March to October 2013, clinical data of 90 patients undergoing primary unilateral total knee arthroplasty were randomized to the tranexamic acid group and the control group, including 19 males and 71 females. The 30 patients in the tranexamic acid group received 50 mL of 3%tranexamic acid dilute solution inside knee joint after capsule closure, and 60 patients in the control group received the same volume of physiological saline. No significant difference in age, height, body mass index, anticoagulation, the type of prosthesis, tourniquet time and preoperative diagnosis was detected between the two groups (P>0.05). The amounts of intraoperative and postoperative blood loss and blood transfusion, postoperative drainage volume, the preoperative and postoperative limb circumference 10 cm above the operated knee were recorded. Routine blood test was reviewed after the surgery. RESULTS AND CONCLUSION:There were no significant differences in total blood loss, postoperative drainage volume and limb circumference changes between tranexamic acid and control groups (P>0.05). The amount of postoperative hidden blood loss was significantly less in the tranexamic acid group than in the control group (t=-2.683, P<0.05). These data suggested that the intra-articular injection of tranexamic acid intraoperatively in patients receiving total knee arthroplasty could significantly reduce the amounts of postoperative hidden blood loss, and did not affect the postoperative limb circumference changes.
