The primary concern of this paper is to examine the business networks of Cantonese merchants in the period of 1850s-1910s, based on what the merchants recorded by themselves in the family correspondences and the wills (the probate jurisdiction, the Supreme Court of Hong Kong, Hong Kong Record Series 144). These materials are informative of the testators’ life stories such as origins of emigration, family details, occupation, involvement of businesses, and location of residence. From these materials emerges the networking pattern that made the Cantonese merchants successful at home and overseas. To examine the hidden aspect of cross border networks of Cantonese, this paper will focus on the following issues: How did the Cantonese successfully extend and maintain their networks of business from Guangdong to Hong Kong, South China, Southeast Asia, Australia and North America? To what extent were the family networks interwoven with the business networks and were they effective in helping production, circulation, and consumption? Above all, did the Cantonese overseas network tell us something unique about Chinese practice of capitalism?

Purpose: The aims of this study were to investigate the prevalence of upper tract involvement in ketamine-associated uropathy, and to determine the predictors of hydronephrosis in patients with a history of ketamine abuse. Methods: This was a cross-sectional study of a prospective cohort of patients with ketamine-associated uropathy. Data including demographics, pattern of ketamine abuse, pelvic pain and urgency or frequency (PUF) symptom score, uroflowmetry (UFM) parameters, serum renal function, and liver function tests were collected. Upon consultation, ultrasonography was performed to assess the function of the urinary system. Results: From December 2011 to October 2015, we treated 572 patients with ketamine-associated uropathy. Of these patients, 207 (36.2%) had managed to achieve abstinence at the time of their first consultation. Ninety-six patients (16.8%) in the cohort were found to have hydronephrosis on ultrasonography. Univariate analysis identified age, duration of ketamine abuse, PUF symptom score, voided volume on UFM, serum creatinine levels >100 μmol/L, and an abnormal serum liver enzyme profile as factors associated with hydronephrosis. Logistic regression revealed the following parameters to be statistically related to hydronephrosis: age (adjusted odds ratio [OR], 1.090; 95% confidence interval [CI], 1.020–1.166; P=0.012), functional bladder capacity (adjusted OR, 0.997; 95% CI, 0.995–0.999; P=0.029), serum creatinine >100 μmol/L (adjusted OR, 3.107; 95% CI, 1.238–7.794; P=0.016, and an abnormal serum liver enzyme profile (adjusted OR, 1.967; 95% CI, 1.213–3.187; P=0.006). Conclusions: Ketamine-associated uropathy can involve the upper urinary tract. Patient demographics as well as investigations of UFM, renal function tests, and liver function tests may allow us to identify at-risk patients.
