Fuzi is a medicine used for rescuing from collapse by restoring yang as well as a famous toxic traditional Chinese medicine. In order to ensure the efficacy and safe medication, Fuzi has mostly been applied after being processed. There have been different Fuzi processing methods recorded by doctors of previous generations. Besides, there have also been differences in Fuzi processing methods recorded in modern pharmacopeia and ancient medical books. In this study, the authors traced back to medical books between the Han Dynasty and the period of Republic of China, and summarized Fuzi processing methods collected in ancient and modern literatures. According to the results, Fuzi processing methods and using methods have changed along with the evolution of dynasties, with differences in ancient and modern processing methods. Before the Tang Dynasty, Fuzi had been mostly processed and soaked. From Tang to Ming Dynasties, Fuzi had been mostly processed, soaked and stir-fried. During the Qing Dynasty, Fuzi had been mostly soaked and boiled. In the modem times, Fuzi is mostly processed by being boiled and soaked. Before the Tang Dynasty, a whole piece of Fuzi herbs or their fragments had been applied in medicines; Whereas their fragments are primarily used in the modern times. Because different processing methods have great impacts on the toxicity of Fuzi, it is suggested to study Fuzi processing methods.

In recent years, the discovery and studies on aquaporin have made us have a more in-depth understanding about the physiological and pathological processes of water metabolism. Over years, however, there has been no quantitative study on the target sites of diuretic traditional Chinese medicines at the molecular level. In that case, aquaporin was found to been a new target molecule to explain the efficacy exertion of diuretic traditional Chinese medicines. By studying aquaporin, researchers can understand the implicit meaning of the diuretic effect of traditional Chinese medicines and conduct quantitative studies on the diuretic effect. So far, many scholars have conducted a series of studies in the traditional Chinese medicine field by using the findings on aquaporin and made certain advances. This article provides a summary about the efficacy exertion of diuretic traditional Chinese medicines through target molecule aquaporin.

Puerariae Lobatae Radix, also known as Gegen, is a root derived from Pueraria lobata. Based on field investigation and the developmental anatomy of root tuber, we have elucidated the relationship between the growth of root tuber and the anomalous structure. The results of analysis showed that the root system of P. lobata was developed from seed and adventitious root and there existed root tuber, adventitious root and conductive root according to morphology and function. The root tuber was developed from adventitious root, its secondary structure conformed to the secondary structure of dicotyledon's root. With the development of root, the secondary phloem of root tuber appeared abnormal vascular tissue, which was distributed like ring in the outside of secondary vascular tissue. The root tuber might have 4-6 concentric circular permutation abnormal vascular tissuelobate, and was formed by the internal development of abnormal vascular tissue. The xylem and phloem of abnormal vascular tissue were the main body of the root tuber. The results reveal the abnormal anatomical structure development of P. lobata, also provides the theoretical basis for reasonable harvest medicinal parts and promoting sustainable utilization of resources of P. lobata.

Objective: To investigate the mechanisms of electroacupuncture (EA) at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) in intervening diabetic gastroparesis (DGP) based on calcium-activated chloride channel. Methods: Forty Sprague-Dawley rats were randomly divided into four groups, including a normal control group (group A), a model group (group B), an EA group (group C) and a metoclopramide group (group D), with 10 rats in each group. A single intraperitoneal injection of 2％ streptozotocin (STZ) combined with 8-week high-glucose high-fat diet was used to establish a DGP rat model. After intervention, gastrointestinal propulsive rate was observed; the expression level of transmembrane protein 16A (TMEM16A) was examined by immunohistochemistry; the Ca2+ concentration in interstitial cells of Cajal (ICCs) was detected by immunofluorescence; and whole-cell patch-clamp technique was applied to detect the current intensity of calcium-activated chloride channel (ICaCC) in ICCs in gastric antrum. Results: After modeling, the blood glucose levels in group B, group C and group D were significantly increased compared with group A (all P<0.01); after intervention, compared with group B, the blood glucose levels in group C and group D were significantly decreased (P<0.05, P<0.01); the intra-group comparison of blood glucose level between after modeling and after intervention found significant difference only in group C (P<0.01). The gastrointestinal propulsive rates in group B, group C and group D were significantly different from that in group A (P<0.01 or P<0.05); the gastrointestinal propulsive rates were markedly higher in group C and group D than in group B (P<0.01, P<0.01). The expressions of TMEM16A in group B and group C were decreased compared with group A (P<0.01, P<0.05); the expressions of TMEM16A in group C and group D were increased compared with group B (P<0.01, P<0.05). The fluorescence intensity of Ca2+ was significantly lower in group B than in group A (P<0.01); the fluorescence intensity of Ca2+ was significantly higher in group C and group D than in group B (P<0.01, P<0.05). ICaCC in ICCs in group B was significantly decreased compared with group A; ICaCC in group C and group D were increased compared with group B. Conclusion: EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) can significantly improve gastrointestinal motility in DGP rats by up-regulating the ICaCC in ICCs.

OBJECTIVETo evaluate the effect of vertebral height restoration of vertebroplasty for osteoporotic vertebra compression fractures (VCFs).

METHODSFrom 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.

RESULTSAll 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.

CONCLUSIONVertebroplasty 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.

OBJECTIVETo explore surface roughness of bone cement and surround tissue on histological characteristic of induced membranes.

METHODSBone cements with smooth and rough surface were implanted in radius bone defect, intramuscular and subcutaneous sites of rabbits, and formed induced membranes. Membranes were obtained and stained (HE) 6 weeks later. Images of membrane tissue were obtained and analyzed with an automated image analysis system. Five histological parameters of membranes were measured with thickness,area,cell density,ECM density and microvessel density. Double factor variance analysis was used to evaluate the effect of the two factors on histological characteristics of induced membranes.

RESULTSMembranes can be induced by each kind of bone cement and at all the three tissue sites. In histological parameters of thickness,area and micro vessel,there were significant differences among the membranes induced at different tissue sites (P = 0.000, P = 0.000, P = 0.000); whereas, there were no significant differences in histological parameters of cell density and ECM density (P = 0.734, P = 0.638). In all five histological parameters of membranes, there were no significant differences between the membranes induced by bone cements with different surface roughness (P = 0.506, P = 0.185, P = 0.883, P = 0.093, P = 0.918).

CONCLUSIONSurround tissue rather than surface roughness of bone cements can affect the histological characteristics of induced membranes. The fibrocystic number, vascularity, mechanical tension and micro motion of the surround tissue may be closely correlated with the histological characteristics of induced membranes.

OBJECTIVETo analyze the trend of prevalence and major risk factors for diabetes between 1997 and 2009 in Shenzhen.

METHODSA total sample of 7956 and 8487 residents aged from 20 to 69 years were selected using multi-stage cluster sampling from two cross-sectional chronic diseases survey in Shenzhen in 1997 and 2009 respectively. The variation of prevalence between different age groups (divided into a 5-year age group) were compared. The effect of risk factors was evaluated by population attributable risk percentage (PARP), and time trend of PARP for risk factors were analyzed.

RESULTSCompared with that in 1997, the aged-adjusted prevalence of diabetes has increased from 3.85% (306/7956) to 5.21% (441/8487) in 2009 (χ(2) = 17.54, P < 0.001). The prevalence in age group 50 - 54, 60 - 64, and 65 - 69 years increased significantly from 7.88% (35/444), 8.55% (36/421) and 11.34 (33/291) to 12.09% (59/488), 14.63% (55/376) and 20.71% (70/338) respectively (χ(2) = 4.54, 7.25 and 10.01, P < 0.05). After controlling for age, the rates of abdominal obesity, family history of diabetes, dyslipidemia and hypertension increased from 21.56% (1715/7956), 4.39% (349/7956), 26.34% (2096/7956) and 11.53% (917/7956) to 31.88% (2706/8487), 12.84% (1090/8487), 41.38%(3512/8487) and 14.61% (1240/8487) respectively (χ(2) = 5.52, 14.83, 18.38 and 20.22, P < 0.01). For diabetes, the PARP of aging, dyslipidemia and abdominal obesity were 41.55%, 29.25% and 25.10% respectively.

CONCLUSIONThe prevalence of diabetes in Shenzhen increases rapidly and more patients are found in younger age. The rise of diabetes was mainly attributed to aging and increasing exposures to risk factors.
