Objective To compare the immediate effects of extracorporeal shock wave therapy with that of joint mobilization plus short wave therapy in treating scapulohumeral periarthritis, and to elucidate the mechanism of extracorporeal shock wave therapy and how it should be used. Methods Forty-seven patients diagnosed with scapulohumeral periarthritis were selected and randomized into two groups, a treatment group (n = 26) treated with extracorporeal shock wave therapy, and a control group ( n = 21 ) treated with joint mobilization plus short wave therapy. The short form of the McGill pain questionnaire (SF-MPQ) and range of motion (ROM) measurements were used to evaluate shoulder function. Results Compared with baseline, both groups improved significantly af-ter treatment, but the immediate effect in the treatment group was superior to that in the control group. Concln-sions As a safe, time-saving and effective therapy, extracorpnreal shock waves could be used to treat scapulo-humeral periarthritis.

Objective To systematically review the existing evidence about the effect of medial and lateral (crossed) entry pins versus only lateral entry pin fixation on the supracondylar fractures of the humerus in children.Methods Eligible studies were identified in Cochrane library,the Cochrane Bone,Joint and Muscle Trauma Group (till March 2011 ),Medline (from 1966 to March 2011 ),EMbase (from 1966 to 2011 ),CBM (from January 1979 to March 2011 ),PubMed,Wanfang Data (from 2000 to March 2011 ) and CNKI and the references of the included studies and several Chinese orthopedic journals were manually searched.Then,the randomized controlled trials (RCTs) and quasi-randomized controlled trials (CCTs) about two entries (crossed and only lateral pinning) for supracondylar fractures of humerus in children were collected.After evaluation of methodology with the enrolled studies,available data was extracted and systematic review was conducted via the method recommended by the Cochrane Collaboration.Results In total,five RCTs involving 311 patients were involved.Compared with the preoperative data,the meta-analysis results showed no significant difference in reduction stability in terms of change in Baumann angle and Carrying angle between the two groups.For the postoperative function outcome including complete reduction,Flynn grade and full return to function,no significant difference was found between the two groups.For the postoperative complications,there was no difference in the infection of pin tract,though lateral entry resulted in a significant lower incidence of the iatrogenic nerve injury compared with the medial and lateral entry.Conclusions With the Kirschner wire fixation for supracondylar fractures of humerus in children,current existing evidences indicate that the lateral entry of pinning has similar results in reduction stability,function outcome and incidence of pin tract infection compared with medial and lateral entry.Nevertheless,lateral entry,as a safe pinning technique,may effectively decrease the risk of iatrogenic nerve injury

This article provides the possible mechanism of acupuncture-moxibustion repair of gastric mucosal injury from central regulation and puts it forward that the nucleus of solitary tract is the primary regulation center for the injury repair and has the effect of collecting and integrating information. In addition, it is put forward that neural regulation is a main regulatory mechanism for the injury repair and besides, endocrine, immune and humoral regulations participates in the modulation and gastric mucosal repair involves a composite regulatory mechanism in which the central nervous system, neuroendocrine-immune network and neurohumoral regulation take part.

Objective To investigate the prevalence of chronic kidney disease (CKD) and associated factors in Changsha county of Hunan province. Methods Using a stratified, multistage sampling, 1950 residents (older than 20 years old) from 3 towns of Changsha county were randomly selected to be interviewed and tested for the kidney damage indicators and the associated factors with CKD. Results Eligible data of 1727 subjects were enrolled in the study. After the adjustment of age and gender compenent, the prevalence of albuminuria was 8.5%, hematuria 5.1%, and reduced eGFR 1.5%. Approximately 14.6% subjects had at least one indicator of kidney damage, and the awareness rate was 16.5%. Age, hypercholesteremia, hypertriglyceridemia, hypertension and diabetes were independently correlated with albuminuria. Female, age, hypertriglyceridemia and hyperuricemia were independently correlated with reduced renal function. Female was independently correlated with hematuria. Conclusions The prevalence of chronic kidney disease is 14.6% and the awareness rate is 16.5% in suburban adult population of the central south area of China. The spectrum and correlated factors of CKD in this county undergoing fast economic development are close to those of Guangzhou and developed countries.

Objective:To observe the effect of moxibustion on the mRNA and protein expressions of heat-shock protein 70 (HSP70) in gastric cancer-bearing rats. Methods: A total of 40 healthy Sprague-Dawley (SD) rats were adaptively fed for one week. The gastric cancer model was prepared by Walker-256 cancer tissue transplantation. After 7 d, 10 rats were randomly selected to verify the successful modeling, and the remaining 30 rats were divided into a model group, a moxibustion group and an infrared group by the random number table method, with 10 rats in each group. After enrollment, the moxibustion group received suspended moxibustion at Zhongwan (CV 12), Guanyuan (CV 4) and bilateral Zusanli (ST 36), (the first group of acupoints) on the 1st day, and suspended moxibustion at bilateral Pishu (BL 20) and Weishu (BL 21), (the second group of acupoints) on the 2nd day, 20 min each time, once a day. Moxibustion was alternately performed every other day at the two groups of acupoints for 21 d. From the day of enrollment, rats in the infrared group were irradiated with the infrared radiation at the stomach area on the 1st day, and at the T12-T13 interspinous region on the 2nd day, 20 min each time, once a day, and the two locations were alternately irradiated every other day for 21 d. During the treatment, rats in the model group were intervened by grasping and fixation without treatment. At the end of the treatment, blood was collected from the inner eye orbit, and the HSP70 expression in peripheral blood was determined by enzyme linked immunosorbent assay (ELISA). Rats were sacrificed, the tumor volume and growth inhibition rate were measured. The position and changes of HSP70 in gastric cancer were observed by streptavidin-perosidase (SP); HSP70 protein expression was determined by ELISA; HSP70 mRNA expression in cancer tissues was determined by reverse transcription-polymerase chain reaction (RT-PCR) assay. Results: In comparison of the model group, the volume growth of the gastric cancer in the moxibustion group was significantly restricted (P＜0.01); the volume growth inhibition rate in the moxibustion group was 37.93%; the HSP70 expression in peripheral blood and the cancer tissues was significantly increased (both P＜0.01); the expression of HSP70 mRNA and HSP70 content in gastric tumor were both obviously increased in the moxibustion group (P＜0.01); and a large amount of HSP70 was released to the outside of cancer cells in the moxibustion group. In comparison of the model group, the volume growth of the gastric cancer in the infrared group was slightly restricted (P＜0.05) with a volume growth inhibition rate of 15.89%; the HSP70 expression in the infrared group was increased significantly in peripheral blood (P＜0.01) and in the gastric cancer tissues (P＜0.05); more HSP70 was released outside of the cancer cells in the infrared group. In comparison of the infrared group, the volume growth of gastric cancer was more restricted in the moxibustion group (P＜0.05), and the HSP70 expression in the gastric cancer tissues was also higher (P＜0.05); more HSP70 was released outside of the cancer cells in the moxibustion group. Conclusion: Moxibustion and infrared treatment inhibit the gastric cancer growth in the gastric cancer-bearing rats, up-regulate the HSP70 expression in gastric cancer tissues, and promote the production and extracellular release of HSP70, and the effect of moxibustion is more obvious.

Objective To investigate the risk factors and treatment for infections after spinal internal fixation surgery. Methods The clinical data of 472 patients who underwent spinal internal fixation surgery from January 2012 to December 2012 was analyzed retrospectively, an average age of 50. 6 years (38~78 years). All cases were underwent posterior procedures. All infected patients received emergency opera-tion of wound debridement, drainage and sensitive antibiotic treatment. The mean follow-up time was 11 months (8~19 months). Risk fac-tors and treatment for infections were summarized and discussed. Results Of 472 patients,postoperative infections occurred in 9 cases with the infection rate of 1. 91%. The operation time,intraoperative blood and postoperative drainage was 100~325 min,200~1500 mL and 65~1350 mL,respectively,which were greater than the similar surgeries of same period. The initial signs of wound infection was observed at 10 d (6~16 d) after surgery. CRP,ESR and WBC were significantly increased in 4~7 d after surgery,and maintained at high level at least for 14 d. Bacterial culture results showed infection bacteria were mainly common skin flora. One infection recurred during followed-up and subse-quent treatment was successful. Conclusion Wound infection after internal fixation mainly occurred in the posterior procedure of spine, which were deep infection. The main clinical manifestation was the wound exudate and local deep tenderness,fever and wound surface swelling were relatively rare. Increased intraoperative bleeding,postoperative drainage volume,operation time were the risk factors,which lead to perio-perative malnutrition and subsequent infections. Debridement,drainage,and intravenously sensitive antibiotics could obtain an ideal outcome for most cases. It was not necessary to remove the internal fixation instrument and bone grafting.

Objective To observe the time characteristics of acute aortic dissection (AAD) in Urumqi and its peripheral areas in Xinjiang Uygur autonomous region, and to explore the effect of meteorological conditions on the onset of AAD.Methods Retrospective analysis of the related data of the adult AAD patients diagnosed by imaging examination, and admitted to the First Affiliated Hospital of Xinjiang Medical University from March 2010 to July 2016 was performed. The onset time, the contemporaneous meteorological data, including daily minimum, average, and the highest temperature, daily average air pressure, daily average relative humidity, daily precipitation, daily average wind speed, daily maximum wind speed, and sunshine duration per day were collected. Analysis of concentrated distribution trend of the AAD onset was done by circular distribution statistics. Meteorological conditions were compared between the AAD day and no AAD day. The changes of air temperature 5 days before onset were observed.Results A total of 379 patients were enrolled, with 307 male and 72 female. The ratio of male to female was 4.19:1, the average age was 52.27±12.18; and the underlying diseases was hypertension (about 58.05%); the incidence sites were Urumqi and Changji city. ① The incidence of AAD in Urumqi and its peripheral areas had clear concentrated trend, and the peak period of AAD corresponded to January 1st to 2nd (homogeneity testr = 0.104,r0.05 = 0.009,P < 0.05). ② The minimum, mean and maximal atmospheric temperatures on the AAD day were lower than no AAD day [℃: 4.10 (-9.55, 14.60) vs. 7.75 (-6.70, 16.20), 14.10 (-1.50, 25.00) vs. 17.50 (0.60, 26.78), 8.50 (-6.22, 19.45) vs. 12.10 (-3.60, 20.90), allP < 0.05], sunshine duration was significantly shorter than no AAD day [hours: 8.50 (4.60, 10.70) vs. 8.90 (5.50, 11.50), P< 0.01], and atmospheric pressure were higher than no AAD day [kPa: 91.24 (90.66, 91.75) vs. 91.12 (90.62, 91.61), 19.11 (18.99, 19.22) vs. 19.09 (18.98, 19.19), bothP < 0.05]; there were no significant differences in the incidence of daytime temperature difference, average relative humidity, precipitation, average wind speed, and maximum wind speed between the two groups. ③ the peak period of AAD occurrence was December (38 cases), which was followed by January (36 cases); and there were 26 cases of each month in May, June, July, and September, which were lower than the rest of months. It was shown by the temperature distribution that the minimum average temperature was in January (-12.46 ℃), followed by December (-9.03 ℃); the maximum average temperature was in July [(24.59±3.21)℃], followed by August [(23.14±3.64)℃]. ④ The patients was sorted according to the quartile of daily mean temperature, into < -5.2 ℃, -5.2-10.7 ℃, 10.7-20.4 ℃, and > 20.4 ℃ groups, and each group had 104, 99, 98, 78 cases of AAD, respectively. The number of AAD in lowest temperature group was 1.33 times of the highest temperature group. In the 45-59 and 60-74 years, the number of AAD in lowest temperature group was higher than that in the highest temperature group (50 vs. 36, 26 vs. 13). In patients with hypertension, the number of AAD in lowest temperature group was higher than that in the highest temperature group (60 vs. 44). ⑤ The maximum air temperature, mean air temperature of the day from 5 days before to the onset day of AAD, and the lowest temperature from 3 days before to the onset day of AAD display slowly decrease trends, but there was no significant difference in daily temperature.Conclusions The incidence of AAD in Urumqi and its peripheral areas was concentrated from January 1st to 2nd of each year. When the temperature was lower than -5.2 ℃, AAD were more likely to attack. The 5 days changes of temperature and daily temperature before the attack were relevant with onset of AAD. It was speculated that the weather conditions such as air temperature may affect patient who has a past history of cardiovascular disease to attack AAD.
