Effects of group mindfulness-based cognitive therapy and group cognitive behavioural therapy on symptomatic generalized anxiety disorder: a randomized controlled noninferiority trial.

BACKGROUND: Mindfulness-based cognitive therapy (MBCT) is a promising alternative treatment for generalized anxiety disorder (GAD). The objective of this study was to examine whether the efficacy of group MBCT adapted for treating GAD (MBCT-A) was noninferior to group cognitive behavioural therapy (CBT) designed to treat GAD (CBT-A), which was considered one of first-line treatments for GAD patients. We also explored the efficacy of MBCT-A in symptomatic GAD patients compared with CBT-A for a variety of outcomes of anxiety symptoms, as well as depressive symptoms, overall illness severity, quality of life and mindfulness. METHODS: This was a randomized, controlled, noninferiority trial with two arms involving symptomatic GAD patients. Adult patients with GAD (n = 138) were randomized to MBCT-A or CBT-A in addition to treatment as usual (TAU). The primary outcome was the anxiety response rate assessed at 8 weeks after treatment as measured using the Hamilton Anxiety Scale (HAMA). Secondary outcomes included anxiety remission rates, scores on the HAMA, the state-trait anxiety inventory (STAI), the Hamilton Depression Scale (HAMD), the Severity Subscale of the Clinical Global Impression Scale (CGI-S), and the 12-item Short-Form Health Survey (SF-12), as well as mindfulness, which was measured by the Five Facet Mindfulness Questionnaire (FFMQ). Assessments were performed at baseline, 8 weeks after treatment, and 3 months after treatment. Both intention-to-treat (ITT) and per-protocol (PP) analyses were performed for primary analyses. The χ2 test and separate two-way mixed ANOVAs were used for the secondary analyses. RESULTS: ITT and PP analyses showed noninferiority of MBCT-A compared with CBT-A for response rate [ITT rate difference = 7.25% (95% CI: -8.16, 22.65); PP rate difference = 5.85% (95% CI: - 7.83, 19.53)]. The anxiety remission rate, overall illness severity and mindfulness were significantly different between the two groups at 8 weeks. There were no significant differences between the two groups at the 3-month follow-up. No severe adverse events were identified. CONCLUSIONS: Our data indicate that MBCT-A was noninferior to CBT-A in reducing anxiety symptoms in GAD patients. Both interventions appeared to be effective for long-term benefits.

[Adjuvant treatment of penetrating moxibustion at governor vessel for persistent allergic rhinitis of deficiency-cold syndrome].

OBJECTIVE: To explore the efficacy and action mechanism of penetrating moxibustion at governor vessel for persistent allergic rhinitis of deficiency-cold syndrome. METHODS: Ninety patients with persistent allergic rhinitis of deficiency-cold syndrome were randomly divided into an observation group (n = 45) and a control group (n = 45). The patients in the control group were treated with momethasone furoate nasal spray, 2 sprays per side per time, once a day. On the basis of treatment in the control group, the patients in the observation group were additionally treated with penetrating moxibustion at governor vessel, 2 h per treatment, once a week. Both groups were treated for 4 weeks. The TCM symptom score, visual analogue scale (VAS) score and rhinoconjunctivitis quality of life questionnaire (RQLQ) score were observed in the two groups before and after treatment. The serum level of immunoglobulin E (IgE) and complete blood count of eosinophil (EOS) were measured before and after treatment, and the clinical effects were compared. RESULTS: Compared before treatment, the TCM symptom scores, VAS scores, RQLQ scores, serum levels of IgE and complete blood count of EOS in the two groups were all reduced after treatment (P<0.05), and those in the observation group were lower than those in the control group (P<0.05). The total effective rate in the observation group was 95.6% (43/45), which was higher than 82.2% (37/45) in the control group (P<0.05). CONCLUSION: Based on the momethasone furoate nasal spray, the adjuvant treatment of penetrating moxibustion at governor vessel could significantly improve the clinical symptoms in patients with persistent allergic rhinitis of deficiency-cold syndrome, and its mechanism may be related to the regulation of immune disorder.

[The application of computer aided design and computer aided engineering technique in separation of Pygopagus conjoined twins].

OBJECTIVES: To explore the effect of CAD and CAE related technique in separation of Pygopagus Conjoined Twins. METHODS: CT images of Pygopagus conjoined twins were obtained and reconstructed in three-dimensional by Mimics software. 3D entity model of skin and spine of conjoined twins were made by fast plastic technique and equipment according to 3D data model. The circumference and area of fused and independent dural sac were measured by software of AutoCAD. RESULTS: The entity model is real reflection of skin and spine of Pygopagus. It was used in the procedures of discussion, sham operation, skin flap design and informed consent. In the measure of MRI, the circumference and area of fused dural sac was more than of independent dural sac, that is to say, the defect of dural sac can be repaired by direct suture. The intraoperative finding match with imaging measure results. CONCLUSIONS: The application of CAD and CAE in the procedure of preoperative plan have gave big help to successful separation of Pygopagus Conjoined Twins.

[Comparison of clinical effects of total artificial hip replacement and cannulated screw fixation for the treatment of displaced femoral neck fractures in elderly patients].

OBJECTIVE: To compare of clinical effects of different surgical methods in the treatment of elderly femoral neck fractures. METHODS: From January 2013 to June 2016, 144 elderly patients with femoral neck were treated and divided into artificial hip replacement group and cannulated screw fixation group according to the surgical methods. In the total hip arthroplasty group, there were 89 cases, 28 males and 61 females, with an average age of(84.10±3.10) years old;Hollow nail fixation group 55 cases, 20 males and 35 females, with an average age of (86.80±2.88) years. Preoperative patients data, postoperative complications, mortality and postoperative Harris hip score were compared between the two groups. RESULTS: A total of 144 cases were followed up for 12 to 36 months with an average of 18 months. There was no significant difference between two groups in gender, fracture side, preoperative complications, osteoporosis, ASA score, injury to surgery interval, the number of patients admitted to ICU and perioperative death. However, the patients in hollow screw fixation group was older than the joint replacement group(t=5.311, P<0.05);The degree of preoperative fracture displacement in the joint replacement group was higher than that in the hollow nail fixation group(χ²=6.894, P=0.009<0.05);Hollow nail fixation group in operation time, hospital stay, intraoperative blood loss, perioperative blood transfusion was significantly better than the number of joint replacement group(P<0.05);The Harris score of the joint replacement group was higher than that of the hollow screw fixation group(P<0.05). CONCLUSIONS: For elderly femoral neck patients, if there is a significant shift in the fracture (Garden III, IV), the preferred treatment is hip replacement. Postoperative complications are relatively small, satisfactory joint function recovery. If the fracture displacement is not obvious (Garden type I, II) or patients with more medical diseases, poor physical condition, poor surgical tolerance, postoperative life expectancy is not high, the first choice is closed reduction and cannulated screw fixation.

[Effects of vertebral height restoration of vertebroplasty for osteoporotic vertebra compression fractures].

OBJECTIVE: To evaluate the effect of vertebral height restoration of vertebroplasty for osteoporotic vertebra compression fractures (VCFs). METHODS: From October 2004 to June 2007, a total of 37 patients with 40 VCFs were treated by vertebroplasty. There were 12 males and 25 females with a mean age of (72.4 +/- 12.7) years (ranged, 48 to 87). Pain easement state was evaluated by visual analog scale (VAS) before and after operation, as well as in followed-up. Preoperative and postoperative vertebral height, kyphosis angle at fractured levels were measured on X-rays. RESULTS: All of patients were followed-up for 12 to 47 months (averaged, 35.8 +/- 9.6). The VAS score was 8.4 +/- 1.6 before operative, 2.1 +/- 1.2 at the 2nd day after operative, there were significant difference between pre-and postoperative (P < 0.05); the average follow-up VAS was 1.6 +/- 0.9, there were significant difference as compared with the preoperative (P < 0.05). Lateral X-ray showed that the preoperative degree of vertebral height in the of anterior and middle vertebral were (72.0 +/- 10.6)% and (68.0 +/- 15.6)%, and postoperative were (76.0 +/- 8.6)% and (73.0 +/-6.1)%, respectively. There were no significant difference in vertebral height between preoperative and postoperative. The vertebral kyphosis angle was corrected from preoperative (7.8 +/- 2.7) degree to postoperative (8.1 +/- 2.3) degree. CONCLUSION: Vertebroplasty is a safe and effective method for treatment of osteoporotic VCFs, it can relieve the pain effectively. Failure to restore vertebaral height does not seem to interfere with the excellent pain management.

Calcium pentosan polysulfate and sodium pentosan polysulfate may be used to treat intervertebral disc degeneration.

Intervertebral disc degeneration (IDD) is a major health problem world-wide, and several spinal disorders are closely associated with it. Although people have invested a great deal of time and effort, how to prevent and reverse the IDD for the researchers is still a difficult and hot issue. Intervertebral disc belongs to cartilage tissue, and IDD also is the cartilage degeneration disease. A large quantity of studies have shown that Calcium pentosan polysulfate (CaPPS) and sodium pentosan polysulfate (NaPPS) possess chondroprotective activities and play an important role in maintaining cartilage integrity. We reasonably hypothesize that NaPPS and CaPPS may be used to treat IDD. The possible mechanism may include that: (1) the significant effects of NaPPS and CaPPS in improving capillary blood flow could maintain nutritional supply to intervertebral disc, and preserve intervertebral disc tissue against degeneration; (2) CaPPS and NaPPS preserve cartilage integrity, proteoglycan synthesis, and improve cartilage biomechanical properties; (3) as the multifaceted exosite inhibitors of proteinases NaPPS and CaPPS strongly impede the activity and production of proteinases; (4) promotion of the balance between proteinases and TIMPs also may be involved in treating IDD; (5) NaPPS and CaPPS exhibit potent anti-inflammatory effects, and then reduce inflammation-induced IDD. If the hypothesis were conformed, the symptoms caused by IDD and its related diseases would be a corresponding alleviation or even disappearance, which could greatly alleviate the suffering of patients from disc degeneration diseases. Certainly, many roles of CaPPS and NaPPS, such as effectiveness, safety and side effects, need to be tested, and further works such as animal model and clinical trial, need to be done to prove this hypothesis.
