The education of traditional Chinese medicine appeared in the 1990s in Australia and has been under the supervision of Australian Health Practitioner Regulation Agency (AHPRA) since 2011.Six institutions,including three comprehensive universities—University of Technology Sydney,Western Sydney University and Royal Melbourne Institute of Technology University,have set up programs and offered the bachelor and the master of traditional Chinese medicine so far.This paper chiefly introduced and analyzed the current education status,size and characteristics of traditional Chinese medicine of the three universities with the provision of a reference for the international development and cooperation in traditional Chinese medical education with high quality.

OBJECTIVE:To observe the clinical efficacy and ADR of ultrasound debridement combined with Huangma tinc-ture in the treatment of diabetic foot ulcer. METHODS:90 diabetic foot ulcer patients were randomly divided into combination treatment group(ultrasound debridement combined with Huangma tincture wet compress),Huangma tincture group(Huangma tinc-ture wet compress) and control group (vaseline) with 30 cases in each group. 3 months after treatment,Ulcer healing rate,cure time,effective time,recovery time,cure rate and ADR were observed in each group. RESULTS:The ulcer healing rate of combi-nation treatment group was significantly higher than that of Huangma tincture group and control group,with statistical significance (P<0.05);there was statistical significance between Huangma tincture group and control group(P<0.05). Mean cure time,effec-tive time and recovery time of combination treatment group were all significantly lower than Huangma tincture group and control group,with statistical significance(P<0.05);there was statistical significance between Huangma tincture group and control group (P<0.05). Cure rate of combination treatment group was higher than that of Huangma tincture group and control group,with statis-tical significance (P<0.05);there was statistical significance between Huangma tincture group and control group (P<0.05). No ADR was found in combination treatment group and Huangma tincture group. CONCLUSIONS:The ultrasound debridement com-bined with Huangma tincture in the treatment of diabetic foot ulcer improve healing rate and shorten healing time significantly with-out obvious ADR. It has good clinical efficacy.

Objective To investigate the effects of glucocorticoid on the changes of serum cortisol and 24-hour urinary cortisol in patients undergoing rheumatic valve replacement.Methods 86 patients undergoing rheumatic valve replacement were respectively given 1000 mg methylprednisolone during extracorporeal circulation and intravenously injected 10 mg dexamethasone on the first three days after operation.The enzyme-linked immunosorbent assay (ELISA) was taken to detect the serum cortisol concentration and 24-hour urinary cortisol on the day before operation,the 1st,3rd,5th,and 7th day after surgery.The postoperative complications such as the surgical incision and pulmonary infection were observed during the recovery days.Results Serum cortisol concentrations for patients with different preoperative cardiac function classifications had no significant difference at each observation point during the perioperative period (P＞0.05).Serum cortisol concentration showed a downward trend during the first 3 days after surgery.The serum cortisol level on the 3rd day after surgery was lower compared with that before surgery (P＜0.05),whereas 3 days later the serum cortisol concentration increased gradually and got back to the preoperative levels on the 5th day after surgery.The 24-hour urinary cortisol rose to the peak level on the 1st day after surgery,then decreased to the preoperative level on the 3rd day after surgery (P＞0.05).All the patients recovered.No one died or had complications such as pulmonary infection or incisions healing problems.Conclusions The effects of corticosteroids on perioperative serum cortisol levels in patients with rheumatic heart disease were not clearly correlated with preoperative cardiac function classification.Using glucocorticoid in the first three days after surgery reveals transient inhibitory effect on serum cortisol secreting,however,the cortisol level can quickly go back to the preoperative level after stopping giving glucocorticoid.

Objective:To compare the clinical effects of hip arthroplasty through direct anterior approach (DAA) in lateral decubitus in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia.Methods:The prospective study method was used to select the patients who needed hip arthroplasty in the Fourth Department of Orthopedics, the Second Affiliated Hospital of Harbin Medical University from January 2015 to December 2019. All of them were operated with lateral decubitus DAA. According to the inclusion criteria, they were divided into Kacshin-Beck disease hip osteoarthritis group (group A) and congenital acetabular dysplasia hip osteoarthritis group (group B). Hip Harris score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, visual analogue scale (VAS) score were conducted, and hip abduction angle and flexion angle were measured before surgery, 3, 14 days and 1, 3, and 12 months after surgery.Results:Nineteen and twenty-two patients were included in group A and group B, respectively. All patients successfully completed the surgery. There was no significant difference in Harris score between the two groups before surgery, 3, 14 days, and 1, 12 months after surgery ( P > 0.05). There were no significant differences in WOMAC score, VAS score, hip abduction angle and hip flexion angle between the two groups before surgery and each time point after surgery ( P > 0.05). In the same group, there were significant differences in Harris score, WOMAC score, VAS score, hip abduction angle and hip flexion angle at different time points ( P < 0.001). All postoperative indicators were significantly improved compared with those before surgery. Conclusions:There is no significant difference in the clinical effects of hip arthroplasty through lateral decubitus DAA in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia. This surgical method has good therapeutic effect on both types of hip osteoarthritis.

Kashin-Beck disease (KBD) is a disabling osteoarthropathy of unknown cause, which occurs most frequently in children and adolescents and affects many regions in China. In adults KBD patients, the degeneration of weight-bearing joints is the most serious, especially the knee joint. Up to now, there are still a large number of adult patients with KBD arthritis of the knee, and they have not been systematically and effectively treated. The main manifestations are knee joint pain, thickening, deformation and restricted movement. In severe cases, it can lead to knee joint varus, valgus, flexion contracture, and rotational deformity, which seriously affects the quality of life and work ability of the patients. Early diagnosis of KBD arthritis of the knee is difficult and there is no effective treatment, so it needs to be differentiated from knee osteoarthritis (OA). KBD and OA have common pathological characteristics. According to the "Consensus of Four-stepladder Program of Knee 0steoarthritis" (2018), OA treatment is divided into four levels: basic treatment, drug treatment, restorative treatment and reconstruction treatment. In this paper, the treatment of KBD arthritis of adult knee joint is summarized, which is also divided into four steps. It is necessary to make stepwise treatments according to the severity of KBD arthritis of the knee and the differences of patient's own condition, so that the limited medical resources can be efficiently used. At the same time, this paper also systematically summarizes the epidemiological characteristics, pathological features and diagnostic criteria of KBD arthritis of the knee, aiming to provide effective reference and guidance for the treatment of KBD arthritis of the knee.

Objective:To investigate the clinical characteristics of choledocholithiasis com-bined with periampullary diverticulum and influencing factor for difficult cannulation of endoscopic retrograde cholangiopancreatography (ERCP).Methods:The retrospective case-control study was conducted. The clinical data of 1 920 patients who underwent ERCP for choledocholithiasis in 15 medical centers, including the First Hospital of Lanzhou University, et al, from July 2015 to December 2017 were collected. There were 915 males and 1 005 females, aged (63±16)years. Of 1 920 patients, there were 228 cases with periampullary diverticulum and 1 692 cases without periampullary diverticulum. Observation indicators: (1) clinical characteristics of patients with choledocholithiasis; (2) intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis; (3) influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and com-parison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Clinical characteristics of patients with choledocholithiasis. Age, body mass index, cases with complications as chronic obstructive pulmonary disease, diameter of common bile duct, cases with diameter of common bile duct as <8 mm, 8?12 mm, >12 mm, diameter of stone, cases with number of stones as single and multiple were (69±12)years, (23.3±3.0)kg/m 2, 16, (14±4)mm, 11, 95, 122, (12±4)mm, 89, 139 in patients with choledocholithiasis combined with periampullary diverticulum, versus (62±16)years, (23.8±2.8)kg/m 2, 67, (12±4)mm, 159, 892, 641, (10±4)mm, 817, 875 in patients with choledocholithiasis not combined with periampullary diver-ticulum, showing significant differences in the above indicators between the two groups ( t=?7.55, 2.45, χ2=4.54, t=?4.92, Z=4.66, t=?7.31, χ2=6.90, P<0.05). (2) Intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis. The balloon expansion diameter, cases with intraoperative bleeding, cases with hemorrhage management of submucosal injection, hemostatic clip, spray hemostasis, electrocoagulation hemostasis and other treatment, cases with endoscopic plastic stent placement, cases with endoscopic nasal bile duct drainage, cases with mechanical lithotripsy, cases with stone complete clearing, cases with difficult cannulation, cases with delayed intubation, cases undergoing >5 times of cannulation attempts, cannulation time, X-ray exposure time, operation time were 10.0(range, 8.5?12.0)mm, 56, 6, 5, 43, 1, 1, 52, 177, 67, 201, 74, 38, 74, (7.4±3.1)minutes, (6±3)minutes, (46±19)minutes in patients with choledocholithiasis combined with periampullary diverticulum, versus 9.0(range, 8.0?11.0)mm, 243, 35, 14, 109, 73, 12, 230, 1 457, 167, 1 565, 395, 171, 395, (6.6±2.9)minutes, (6±5)minutes, (41±17)minutes in patients with choledocholithiasis not combined with periampullary diverticulum, showing significant differences in the above indicators between the two groups ( Z=6.31, χ2=15.90, 26.02, 13.61, 11.40, 71.51, 5.12, 9.04, 8.92, 9.04, t=?3.89, 2.67, ?3.61, P<0.05). (3) Influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Results of multivariate analysis showed total bilirubin >30 umol/L, number of stones >1, combined with periampullary diverticulum were indepen-dent risk factors for difficult cannulation in patients with periampullary diverticulum who underwent ERCP for choledocholithiasis ( odds ratio=1.31, 1.48, 1.44, 95% confidence interval as 1.06?1.61, 1.20?1.84, 1.06?1.95, P<0.05). Results of further analysis showed that, of 1 920 patients undergoing ERCP for choledocholithiasis, the incidence of postoperative pancreatitis was 17.271%(81/469) and 8.132%(118/1 451) in the 469 cases with difficult cannulation and 1 451 cases without difficult cannula-tion, respectively, showing a significant difference between them ( χ2=31.86, P<0.05). In the 1 692 patients with choledocholithiasis not combined with periampullary diverticulum, the incidence of postopera-tive pancreatitis was 17.722%(70/395) and 8.250%(107/1 297) in 395 cases with difficult cannula-tion and 1 297 cases without difficult cannulation, respectively, showing a significant difference between them ( χ2=29.00, P<0.05). In the 228 patients with choledocholithiasis combined with peri-ampullary diverticulum, the incidence of postoperative pancreatitis was 14.865%(11/74) and 7.143%(11/154) in 74 cases with difficult cannulation and 154 cases without difficult cannulation, respectively, showing no significant difference between them ( χ2=3.42, P>0.05). Conclusions:Compared with patients with choledocholithiasis not combined with periampullary divertioulum, periampullary divertioulum often occurs in choledocholithiasis patients of elderly and low body mass index. The proportion of chronic obstructive pulmonary disease is high in choledocholithiasis patients with periampullary diverticulum, and the diameter of stone is large, the number of stone is more in these patients. Combined with periampullary diverticulum will increase the difficult of cannulation and the ratio of patient with mechanical lithotripsy, and reduce the ratio of patient with stone complete clearing without increasing postoperative complications of choledocholithiasis patients undergoing ERCP. Total bilirubin >30 μmol/L, number of stones >1, combined with periampullary diverticulum are independent risk factors for difficult cannulation in patients of periampullary diverticulum who underwent ERCP for choledocholithiasis.
