Exercise and relaxation decrease blood pressure. Qigong is a traditional Chinese exercise consisting of breathing and gentle movements. We conducted a randomised controlled trial to study the effect of Guolin qigong on blood pressure. In all, 88 patients with mild essential hypertension were recruited from the community and randomised to Goulin qigong or conventional exercise for 16 weeks. The main outcome measurements were blood pressure, health status (SF-36 scores), Beck Anxiety and Depression Inventory scores. In the qigong group, blood pressure decreased significantly from 146.377.8/93.074.1 mmHg at baseline to 135.5710.0/ 87.177.7 mmHg at week 16. In the exercise group, blood pressure also decreased significantly from 140.9710.9/ 93.173.5 mmHg to 129.7711.1/86.077.0 mmHg. Heart rate, weight, BMI, waist circumference, total cholesterol, renin and 24 h urinary albumin excretion significantly decreased in both groups after 16 weeks. General health, bodily pain, social functioning and depression also improved in both groups. No significant differences between qigong and conventional exercise were found. In conclusion, Guolin qigong and conventional exercise have similar effects on blood pressure in patients with mild hypertension. While no additional benefits were identified, it is nevertheless an alternative to conventional exercise in the nondrug treatment of hypertension.

The results offer preliminary evidence that patients presenting with more neurotic symptom and heightened NA probably elicit more catastrophic thoughts about pain.

Rubber band ligation was used in 221 patients with first or second-degree hemorrhoids. All three primary hemorrhoids were ligated at a single out-patient session without anesthesia. Nineteen patients were lost to follow up. For the 202 patients under review, the follow up period ranged from three to 39 months with a mean of 18.4 months and median of 17 months. Excellent or good results were obtained in 183 patients (90.6 per cent). Moderate to severe pain was noticed by 58 patients (28.7 per cent). Further banding was required in 28 patients (13.9 per cent) and hemorrhoidectomy in six patients (3 per cent). The overall complication rate resulting from the treatment procedure was 3.5 per cent.

A detailed bacteriologic study was done on 161 patients operated for appendicitis. Aerobic and anaerobic cultures were taken from the blood, the appendicular lumen, mucosa, serosa, fossa, and from the wound after closure of the peritoneum. There is no correlation between the degree of appendicitis and the incidence of positive blood culture. The infection spread through the appendicular wall as the disease progressed. Aerobic infection was common in early appendicitis but a mixed aerobic and anaerobic infection was predominant in late cases. Late appendicitis, a positive wound culture at the end of the operation, the duration of symptoms of over 36 hours before operation and the age of the patient over 50 years were all associated with an increased incidence of septic complication. From the antibiotic sensitivity on the bacteria isolated, the most effective agent against anaerobes was metronidazole. Effective agents against the aerobes were aminoglycosides and cephalosporins. The best single agent against both anaerobes and aerobes was moxalactum.

These cross-sectional analyses gave results consistent with pain hypervigilance, mediating the relationship of pain catastrophic cognition and anxiety sensitivity with pain-related fear. The net suppression effects of pain catastrophizing point to anxiety sensitivity, enhancing the effect of pain catastrophic cognition on pain hypervigilance. These findings elucidate how the interdependence of dispositional factors might influence pain adjustment and functioning.

Distinct trajectories in pain treatment satisfaction were displayed in the current sample of Chinese patients with different disability grading chronic pain. Within pain treatment, only medication characteristics significantly impacted patients' medical adherence.

In a prospective study, a test for DGP identified patients with celiac disease with similar levels of sensitivity and specificity as standard serologic analysis of anti-tTG. Use of the DGP test before endoscopy could increase the accuracy of the diagnosis of celiac disease. Further studies, in lower-prevalence populations, are required to assess the impact of the test in clinical practice.
