Effect of depressive symptoms on perceived disability in patients with chronic shoulder pain.
Psychological distress may be an important determinant of perceived disability in patients with chronic musculoskeletal disorders. We evaluated the relationship between depressive symptoms and perceived disability in patients with chronic shoulder pain and quantified the contribution made by depression to perceived disability. ⋯ Level 2, prospective cohort study, prognostic study.

The purpose of this study was to estimate the incidence and degree of persistent chronic pain after inguinal hernia repair performed in our hospitals. ⋯ The frequency and intensity of persistent chronic pain or discomfort after inguinal hernia repair was not high or severe. These data will be useful for further studies to determine the best treatment for adult inguinal hernia.

To observe the effects of repeated electroacupuncture (EA) of Zusanli (ST36)- Yanglingquan (GB34) on hypothalamic acetylcholinesterase (AchE) and vesicular acetylcholine (ACh) transporter (VAChT) activities and choline acetyltransferase (ChAT) mRNA and muscarinic M1 receptor (M1R) mRNA expression in chronic constrictive injury (CCI) and/or ovariectomy (OVX) rats so as to reveal its underlying mechanism in cumulative analgesia. ⋯ Repeated EA can significantly up-regulate AChE and VAChT activities and ChAT mRNA and M1R mRNA expressions in the hypothalamus of CCI and OVX+CCI rats, which may contribute to the cumulative analgesic effects of repeated EA and be closely related to the animals' neuromemory ability.

Prevalence and risk factors of chronic post-thoracotomy pain in Chinese patients from Peking Union Medical College Hospital.
In clinical practice, the mechanisms underlying chronic post-surgical pain (CPSP) remain insufficiently understood. The primary goals of this study were to determine the incidence of chronic pain after thoracic surgery and to identify possible risk factors associated with the development of chronic post-thoracotomy pain in Chinese patients. The secondary goal was to determine whether the difference between pre- and post-operative white blood cell (WBC) counts could predict the prevalence of CPSP after thoracotomy. The impact of chronic pain on daily life was also investigated. ⋯ Chronic pain is common after thoracotomy. WBC count may be a new independent risk factoring surgical patients during peri-operative period. Besides, age, diabetes mellitus, acute post-operative pain, and duration of chest tube drainage may also play a role in chronic post-surgical pain occurrence.
