Objective To investigate MRI features and its clinical value in the pigmented nodular synovitis (PVNS) of the knee joint in order to improve the accuracy of diagnosis of the disease.Methods MRI signs of 9 cases with PVNS of knee joint confirmed by operation and pathology were analyzed retrospectively.Results In 9 patients, joint effusion and marginal bone erosion were found.Diffuse thickening of the synovial membrane, multiple soft tissue nodules showed hypointense on T1WI and mixed hypointense and hyperointense on T2WI,were revealed on MRI.Conclusion MRI features of PVNS of the knee joint are characteristic, which reflects the pathological basis and helps to improve the diagnostic accuracy of the disease.

Objective To investigate IL-6 and CRP levels,and their relationship with airflow obstruction、frequency of exacerbation in patients with COPD.Methods From Feb.2004 to Jul.2004,sputum and serum specimens were obtained from 54 patients with stable COPD and 10 age-matched healthy controls.The concentrations of sputum IL-6 and serum IL-6 were measured by ELISA.The concentrations of sputum CRP and serum CRP were measured by transmissive heterometric titration.Results (1)Sputum IL-6 levels in COPD patients of all stages were higher than those in controls(P

BACKGROUND:Studies have shown that the physical development potential is often associates with certain combinations of hand print features.
OBJECTIVE:To analyze the body shape and structure characteristics of national women’s handbal team athletes.
METHODS:Fifty national women’s handbal team athletes were col ected from Shanghai, Beijing, Tianjin and Anhui provinces and PLA. The body shapes of the athletes were measured by the Research Institute of National Sports Council, and the hand prints were col ected. The common factors of body shape and structure characteristics were analyzed with factor analysis method, including height, weight, forearm length, wrist circumference, hand length, hand width and index finger length and large-handedness index.
RESULTS AND CONCLUSION:The body shape and structure characteristics of national women’s handbal team athletes could be divided into four types:long trunk lean type indicator, hand skeleton and muscle fiber development level index, flexible quality indicators as wel as the alertness and mental level indicators. The long trunk lean type indicator was the main factor to affect body shape and structure characteristics of national women’s handbal team athletes.

[Objective] To observe Yishi Oral Liquid effect on treating middle and old aged asthenopia. [Method] Choose 125 cases of middle and old aged asthenopia, and randomly divide them into observation group 65 cases treated wutg Yishi Oral Liquid, and control group 60 cases with Mingmu Rehmannia Pil;meanwhile both groups reduced the time with the eye and made massage on the acupoints around the eyes. [Result] With 2~4 weeks of treatment, in the observation group, 23 cases were cured, 25 had marked effect, 13 effective, 11 had no effect, the total effective rate was 93.85%;for the control one, they were respectively 14,19,16,11 and 81.67%. The comparison showed the observation group was better than control one. [Conclusion] Yishi Oral Liquid treating middle and old aged asthenopia has good clinical effect, can obviously relieve the symptoms of blurred vision, phengophobia, lacrimation and aningerestling eyes, helpful to recovering eyesight.

ObjectiveTo study the relationship among serum levels of interleukin-12 (IL-12), interleukin-2 (IL-2), and soluble interleukin-2 receptor (sIL-2R) in patients with hepatocellular carcinoma (HCC).Methods60 patients were randomized into two groups, group A (n=30) received IL-2 (1 MIU?day -1 for seven days), group B (n=30) served as control. Venous blood levels of IL-12?IL-2 and sIL-2R in all patients were measured by enzyme-linked immunosorbent assay (ELISA) before and after the IL-2 administration. Results There was positive correlation between serum levels of IL-2 and IL-12, negative correlation between serum levels of IL-2 and sIL-2R and no correlation between that of IL-12 and sIL-2R. Mean serum levels of IL-12,IL-2 and sIL-2R significantly (P

It is scanty in reports about the anatomy of the medial thoracic free flap, that which one of the perforating arteries of the internal thoracic artery is the main arterial source of this flap is still in dispute. This investigation was based on dissection of 50 sides of adult cadavers under the operating microscope.Among the perforating arteries of the internal thoracic artery in the upper four intercostal spaces, the second perforating artery presents a higher incidence of occurence, it also possesses a larger caliber and distributing area. So that it would be the first choice as a pedicle artery in the transplantation of the medial thoracic free flap. The next choice is the first perforating artery, because its distributing area is larger than that of the third as well as the fourth arteries.The second intercostal space is the widest among all other spaces. The internal thoarcic artery in this space is located more superficial and stands further apart from the lateral border of the sternum than that in the other three intercostal spaces. All these advantages are in favor for taking the second perforating artery as the pedicle artery of the free flap or even to take the internal thoracic artery of the same segment together with it. If a portion of the second costal cartilage isresected, the first two perforating arteries and their related portion of internal thoracic artery can be involved in the pedicle, and the area of the skin flap will be increased to a large extent.Some of the applied anatomy of the transplantation of the medial thoracic free flap has been discussed.

Objective: To investigate the epidemiological characteristics of pulmonary tuberculosis in Ningbo City from 2011 to 2020, so as to provide the evidence for developing the control measures of pulmonary tuberculosis. Methods: The data pertaining to pulmonary tuberculosis cases in Ningbo City from 2011 to 2020 were collected from the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System. The temporal distribution, population distribution, regional distribution and case report by hospitals were descriptively analyzed. Results: Totally 38 305 pulmonary tuberculosis cases were reported in Ningbo City from 2011 to 2020, with an incidence rate of 48.71/105. The incidence of pulmonary tuberculosis appeared a tendency towards a decline ( P<0.05 ), with an annual reduction rate of 5.29%. There were 15 784 smear-positive cases ( 41.21% ), and the proportion of smear-positive cases appeared a tendency towards a reduction from 2011 to 2015 ( P<0.05 ), and a rise from 2016 to 2020 ( P<0.05 ). The number of reported pulmonary tuberculosis cases peaked from March to May (10 973 cases, 28.65%), and a higher incidence rate of pulmonary tuberculosis was found in men than in women ( 64.55/105 vs. 32.20/105, P<0.05 ). The highest incidence of pulmonary tuberculosis was found in cases at ages of 15 to 25 years ( 72.93/105 ), followed by in cases at ages of 65 years and greater ( 69.97/105 ), and farmers were the predominant occupation among the pulmonary tuberculosis patients ( 12 279 cases, 32.06% ). During the period from 2011 to 2020, pulmonary tuberculosis cases were reported across the 10 districts or counties of Ningbo City, and the top three high incidence of pulmonary tuberculosis were seen in Yinzhou District ( 59.91/105 ), Fenghua District ( 56.19/105 ) and Beilun District ( 56.01/105 ). The proportion of pulmonary tuberculosis cases reported by designated pulmonary tuberculosis hospitals increased from 72.16% in 2011 to 99.74% in 2020 in Ningbo City. Conclusions The incidence of pulmonary tuberculosis appeared a tendency towards a decline in Ningbo City from 2011 to 2020, and the annual decline rate meets the requirements of the WHO strategic goal of ending pulmonary tuberculosis; however, the control measures for pulmonary tuberculosis require to be intensified among men, youths, and farmers.

Hepatocellular carcinoma (HCC) is one of the most common malignancies in China, which serious threat to life and health. Surgical treatment of HCC is one of the most important therapeutic options for long-term survival of HCC patients, including hepatectomy and liver transplantation. Hepatic arterial infusion chemotherapy (HAIC) infused the therapeutic agents directly into the hepatic artery, the main blood supply in HCC, providing higher concentration and reaction rate. HAIC is an effective treatment for hepatectomy of downstaging and adjuvant therapy, which can improve the feasibility of hepatectomy and decrease the recurrence rates after resection. In this paper, we will review the applications and advances of HAIC in surgical treatment of HCC.
