Thank you, Dr. Yang. Hello, everybody. We have issued the 2014 Q1 earnings release this morning. You can find the full release on all financial websites, as well as our IR website. In general, it was a very strong quarter, with both top and bottom line of the company demonstrating strong growth momentum. Following are some financial highlights for the quarter. Total net revenue, which consists of net revenues generated from the network business and hospital business was RMB 252.6 million, $40.6 million in the first quarter of 2014, a 23.9% increase from RMB 203.9 million in the first quarter of 2013.
Gross profit in the first quarter of 2014 was RMB 85.7 million or $13.8 million, a 19.9% increase from RMB 71.5 million in the first quarter of 2013. Net income attributable to ordinary shareholders in the first quarter was RMB 26.7 million or $4.3 million, a 35.4% increase from RMB 19.7 million in the first quarter of 2013. Basic and diluted earnings per ADS in the first quarter of 2014 was RMB 0.59 or USD 0.10 compared with RMB 0.44 or USD 0.07 in the first quarter of 2013. Adjusted EBITDA in the first quarter of 2014 was RMB 97.1 million or $15.6 million, a 16% -- 16.1% increase from RMB 83.6 million in the first quarter of 2013.
For this quarter, our key financial metrics is as following. Our gross margin in the quarter was 33.9% compared to 35.1% in the first quarter of last year, a negative trend of 114 basis points. The main reasons for this are higher compensation, consumables, and other operating expenses in the network business, and a higher compensation expenses for medical staff in Chang'an Hospital. We expect that the higher compensation expenses will have less impact in the sequential quarters.
Selling expense as a percentage of total revenue was 8.6% in the quarter compared to 8.1% in the same quarter last year, a negative trend of 54 basis points. The main reason for this is marketing expenses relating to new centers. Our general and administrative expenses as a percentage of the revenue was 10.1% compared to 12.5% in the same quarter of last year, a positive trend of 237 basis points. This demonstrated our effective control of our general and administrative expenses and other management costs. As a result, the operating margin for the company for the quarter was 15.2% compared to 14.5% in the same quarter of last year, a positive trend of 70 basis points.
Our net profit margin for the company was 10.6% compared to 9.7% in the same quarter of last year, a positive trend of 90 basis points. Based on the above financial highlights, you can see that Q1 was a very strong and profitable quarter for Concord Medical. Net income attributable to ordinary shareholders have grown by 35%, which demonstrated very positive growth momentum and that would carry over to the rest of the year and forward. The top line growth was driven by strong demand for our network services. Growth from Chang'an Hospital, as well as the contribution for new centers opened in 2013.
For instance, the diagnostic centers in our network have seen the patient visits growing by 18% year-over-year. Total number of patients in Chang'an Hospital, both inpatient and outpatient, has grown by over 27% year-over-year. So our business has benefited greatly from the wider coverage of social insurances in China, the increasing health awareness among the general population, and the stronger acceptance of radiotherapy as an effective treatment of cancer, especially for early-stage cancer patients. So we have maintained our financial guidance for 2014 based on the current market condition and management forecast.
Next, I would like to discuss briefly on the strength of our balance sheet. Following is some key highlights of our liquidity position at the end of the Q1. Our cash and restricted cash was totaling RMB 639 million or USD 103 million. The restricted cash with cash collateral for U.S. dollar loans. Also, we have investments in direct financing leases, both current and noncurrent portion, totaling RMB 311 million or $50 million. The financing leases are highly liquid with minimum counter-party risk. The leases of all government hospitals and fixed payment schedules averaging of 3 years. Combined, the total cash, restricted cash and the financing leases was RMB 950 million or USD 153 million. At the end of Q1, our total loan amount was RMB 1,105,000,000, including RMB 740 million in short-term loans and RMB 365 million in long-term loans.
So at the end of the quarter, our net debt position is RMB 155 million or USD 25 million. Given our total assets of RMB 3.9 billion, and our net assets position of RMB 2.3 billion, our net debt leverage is very low, providing us with strong financial flexibility when planning for the CapEx of our future projects. Our EBITDA for the quarter was RMB 97 million and EBITDA for the trailing 12 months was RMB 409 million.
During the quarter, we have drawn down on the IFC facility of USD 20 million convertible loans, which we'll use in the Guangzhou project. The company plans to draw down on the remaining USD 30 million loan, which is a 8-year term loan to finance our Shanghai project, and our plan freestanding radiotherapy centers. In conclusion, we are very pleased with the strong quarter, and we would focus on the implementation of our growth strategy. Now we would like to open up for questions. Thank you.
