Objective: To investigate the epidemiological characteristics of pulmonary tuberculosis ( PTB ) incidence and mortality in Zhejiang Province from 2016 to 2020, so as to provide the evidence for formulating the PTB control strategy. Methods: The data regarding the PTB patients in Zhejiang Province from 2016 to 2020 were collected from the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System. The reported cases and deaths of PTB cases were descriptively analyzed by time, population and regions. Results: A total of 129 985 PTB cases were reported in Zhejiang Province from 2016 to 2020, and the overall reported incidence rate of PTB was 45.81/105, with a tendency toward a decline in the reported incidence ( χ2trend=298.899, P<0.001 ) and an annual decline rate of 3.72%. The prevalence rates of rifampicin resistance, positive etiological tests, negative etiological tests and no etiological results were 1.51%, 47.17%, 46.67% and 4.65%, respectively. A total of 546 PTB deaths occurred in Zhejiang Province from 2016 to 2020, and the reported mortality of PTB was 0.19/105, with a tendency towards a decline ( χ2trend=10.818, P<0.001) and an annual decline rate of 11.99%.The prevalence rates of rifampicin resistance, positive etiological tests, negative etiological tests and no etiological results were 1.83%, 82.97%, 13.37% and 1.83%, respectively. The highest reported incidence ( 92.18/105 ) and mortality ( 1.19/105 ) of PTB was found in patients aged 65 years and older, and farmer was the predominant occupation of PTB cases (60 774 cases, 46.75%) and dead PTB cases ( 345 cases, 63.19% ). In addition, the top three cities with the highest incidence of PTB included Quzhou City ( 66.43/105 ), Jinhua City ( 64.24/105 ) and Lishui City ( 53.91/105 ), and the top three cities with the highest mortality of PTB included Quzhou City ( 0.67/105 ), Lishui City ( 0.27/105 ) and Jiaxing City ( 0.26/105 ). Conclusions Both the reported incidence and mortality of PTB appeared a tendency towards a decline in Zhejiang Province from 2016 to 2020; however, the proportion of positive etiological tests increased. Higher attention should be paid to the elderly aged 65 years and older and and farmers, and active screening and health education are recommended; in addition, PTB control requires to be intensified in highly prevalent regions, including Quzhou City, Jinhua City and Lishui City.

Objective To report the surgical method and treatment outecome of transfer of free upper limb lateral bone-skin flap for repair of bone defects and nonunion in hand and forearm.Methods 17 cases of hand composite trauma,5 cases of forearm composite trauma and 2 cases of nonunion in forearm were treated with free bone-skin flaps in distal humerus,whose pedicle was the posterior branch of radical collateral artery. Area of the flap was 2cm?3cm to 8cm?10cm,length of exseeted bone was 3～6 cm.Results All the bone-skin flaps completely survived,the donor area all achieved primary healing,On postoperative 1～4 years follow-up,the texture of the flap was excellent,and bone union was obtained in all transplants,the donor area of distal lateral humerus became thicker and thicker with new cortical bones formed.According to the upper arm function assessment criterion issued by hand surgery association of Chinese medical association.The hand function had excellent results in 17 cases and good results in 2 cases.Conclusion The bone-skin flap has following advantages:easy dissection,reliable blood supply,and no major vessel needed to be sacrificed,so it is an effective method for repair of skin and soft tissue with bone defects in hand and forearm,It.also can be used to repair refractory nonunion in ulna and radius.

Objective To evaluate the value of ~(125)I permanent plantation in treating osseous metastases.Methods Twenty-two patients with osseous metastases were accepted radioactive seeds ~(125)I permanent plantation.The curative effect was appraised according to the degree of ostalgia relieving and the changing of the radiology imaging in patients.Results Accepted radioactive seeds ~(125)I permanent plantation,relief of pain was obtained and the effective rate is 91%(20/22).However none of the patients showed severe side-effect.Among 32 lesions in 22 cases followed-up by CT in 2 months,4 obtained CR, 18 obtained PR,10 NC and 0 PD.The responsive rate was 68.7%.Conclusion ~(125)I permanent plantation procedure can be a safe and effective method in treating osseous metastases and obtaining good clinical effects with minimal damage and few comnlications.

OBJECTIVETo observe the effect of rosuvastatin on left ventricular cardiac function, arteriosclerotic plaque and high sensitive C-reactive protein (hs-CRP) in hypertensive patients with mild elevation of LDL-C.

METHODSSeventy-nine patients with a SBP of 140-179 mmHg and/or a DBP of 90-109 mmHg and mild elevated LDL-C were treated with rosuvastatin for 12 months (n=40) or not (n=39). The changes of hs-CRP, arteriosclerosis plaque and cardiac function at the end of the 12-months treatment relative to the baseline levels were analyzed.

RESULTSAfter 12 months of treatment, LDL-C was decreased by 33.2% in rosuvastatin group but remained unchanged in patients without rosuvastatin treatment. The left ventricular peak filling rate (LVPFR) increased significantly from 1.85 to 2.59 (P<0.05) and the serum levels of hs-CRP reduced significantly (P<0.05) after rosuvastatin treatment. The size of the plaques reduced significantly after a 12-month rosuvastatin therapy.

CONCLUSIONRosuvastatin therapy on the basis of conventional anti-hypertensive drugs can obviously improve the left ventricular diastolic function and produce favorable effects on arteriosclerotic plaques.

PURPOSEThis study aims to explore the biomechanical mechanism of lower limb injuries to the driver by establishing a finite element (FE) simulation model of collisions.

METHODSFirst a minibus FE model was integrated with a seat belt system. Then it was used to rebuild two collisions together with the total human model for safety (THUMS) provided by Toyota Motor Corporation: a rear-end collision between a minibus and a truck and a head-on collision of a minibus to a rigid wall. The impact velocities of both collisions were set at 56 km/h. The vehicle dynamic response, vehicle deceleration, and dashboard intrusion in the two collisions were compared.

RESULTSIn the minibus rear-end truck collision, the peak values of the von Mises equivalent stress at the tibia and the femur were 133 MPa and 126 MPa respectively; while in the minibus head-on rigid wall collision, the data were 139 MPa and 99 MPa. Compared with the minibus head-on rigid wall collision, the vehicle deceleration was smaller and the dashboard intrusion was larger in the minibus rear-end truck collision.

CONCLUSIONThe results illustrate that a longer dashboard incursion distance corresponds to a higher von Mises equivalent stress at the femur. The simulation results are consistent with the driver's autopsy report on lower limbs injuries. These findings verify that FE simulation method is reliable and useful to analyze the mechanisms of lower limb injuries to the driver in minibus frontal collisions.

OBJECTIVETo screen the radiosensitivity-related genes of colorectal cancer cells.

METHODSGene expression profiles of two different radiosensitivity cells(colorectal cancer cell line Lovo and SW480) were obtained by cDNA array and the differences of gene expression profiles between the two cells were analyzed.

RESULTSGenes of more than 2-fold expressive differentiation were screened. In Lovo cells, 908 up-regulated genes were found, including higher expression genes CEACAM5, THBS1, SERPINE2, ARL7, HPGD, while 1312 genes were down-regulated. In SW480 cells, higher expression genes were SCD, NQ01, LYZ, KRT20 and ATP1B1.

CONCLUSIONGene profiles can reflect the radiosensitivity of colorectal cancer cells, which will provide the choice for the further study of radiosensitivity in colorectal cancer.
