OBJECTIVETo investigate the regulation trend of Jinxin Oral Liquid (JXOL) on the expression of negative regulatory factor of TLR3 signaling pathway SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points.

METHODSTotally 75 BALB/c mice were randomly divided into 5 groups, i.e., the normal control group, the model group, the ribavirin group, the high dose JXOL group, and the equivalent dose JXOL group, 15 in each group. Each group had 3 intervention ways (I, II, and III) with 5 mice treated in each group. BALB/c mice were nasally infected with respiratory syncytial virus (RSV), and treated by different intervention ways. After intervention, mice were killed and their lung tissues were sampled, mRNA expression levels of RSV-M, SOCS1, and IFN-β were detected by Real time PCR. The expression of SOCSl at the protein level was detected by Western blot.

RESULTSCompared with the normal control group, the mRNA expression level of SOCS1 and IFN-β, and the protein expression level of SOCS1 increased significantly in the model group intervened by intervention I and II (all P < 0.01), but the mRNA expression level of IFN-β decreased significantly in model group intervened by intervention III (P < 0.01). Compared with the model group, the mRNA expression level of RSV-M all significantly decreased in the high dose JXOL group and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and III and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of IFN-β significantly decreased in the high dose JXOL group intervened by intervention I and II and the equivalent dose JXOL group intervened by intervention I (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III and the equivalent dose JXOL group intervened by intervention III (all P < 0.01). The protein expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III (all P < 0.01). Compared with the high dose JXOL group, the mRNA expression level of RSV-M decreased significantly in the equivalent dose JXOL group intervened by intervention I and II (P < 0.01). The mRNA expression level of SOCS1 and IFN-β decreased significantly in the equivalent dose JXOL group intervened by intervention I (P < 0.01), but the mRNA expression level of IFN-β increased significantly in the equivalent dose JXOL group intervened by intervention II and III (all P < 0.01). The protein expression level of SOCS1 decreased significantly in the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01).

CONCLUSIONSJXOL could inhibit the expression of SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points. Its regulatory effect might be associated with promoting the expression of interferon type I and further fighting against RSV.

OBJECTIVETo localize the superficial peroneal nerve in surface of the leg and to provide a safety surgical approach to the fibula.

METHODSSixty-six adult legs preserved by 4% formaldehyde solution were studied involving 42 male and 24 female with the average age of 69 years old ranging from 37 to 88 years. There were 35 cases in left and 31 in right. According to the common lateral surgical approach to the fibula, the superficial peroneal nerve and its branches were dissected in 66 embalmed leg-ankle-foot specimens. The specimens were observed and measured.

RESULTSThe superficial peroneal nerve branched from the common peroneal nerve near the anterolateral aspect of the neck of the fibula, transversing through the muscle, deep fascia and superficial fascia. In 12 cases of specimens, superficial fibular nerve extended to the foot with no branches, in 50 cases of specimens it branched out into two before piercing the deep fascia, in the rest 4 cases of specimens, it branched out into two before piercing the muscle.

CONCLUSIONTo avoid injuring the superficial peroneal nerve, the surgical approach to the 2/3 upper part of the fibula is at posterior crural septum, to the 1/3 lower part of the fibula is at anterior crural septum.

OBJECTIVETo evaluate the effect of the prognostic factors on long-term surgical outcome in myringoplasty.

METHODSRetrospective cohort 205 patients (223 ears) with sandwich temporal fascia myringoplasty were analyzed using the multiple logistic regression analysis. The charts of inpatients had undergone myringoplasty before at least 2 years between January 1999 and November 2003 at Beijing Tongren Hospital. Postoperative follow-up rate was 78.2%. Their ages ranged from 12 to 65 years (mean = 34. 3 years). Their durations of disease ranged from 1 month to 25 years (mean = 16.07 months). The effect of prognostic factors on myringoplasty were investigated by variables noted from patients' files such as age, sex, causes of disease, duration of disease, period of dry ear of disease, operation types, places of tympanic membrane perforation, size of tympanic membrane perforation, status of middle ear and status of eardrum.

RESULTSThere were 11 ears with re-perforation of eardrum at the last follow-up. Successful closure of the tympanic membrane perforation was obtained in 95.1% of the ears (212 ears) with 2 to 5 years follow-up. There were 26 ears with other complications at the last follow-up. Operations were successful in 186 patients. The overall take rate of the myringoplasty was 83.4%. Multiple logistic regression analysis (ward) was subsequently carried out on these prognostic factors on overall take rate of the myringoplasty and yielded the following classification. Relative importance of the predictive variables was as follows: size of tympanic membrane perforation (OR = 1.900), duration of disease (OR = 1.003) and period of dry ear of disease (OR = 0.908). Hearing outcomes: the average air-bone gap improvement was 7.0 dB and the average air conduction improvement was 6.8 dB for all 175 myringoplasty procedures.

CONCLUSIONSA long term follow-up was important. Late atelectatic pocket was a late complication and a cause of failure. A relatively smaller tympanic membrane perforation, a relatively shorter duration of disease and a relatively longer period of dry ear of disease were found to be significant prognostic factors positively influencing the success rate of myringoplasty.

OBJECTIVEBased on the registered female breast cancer data from 1998 to 2007, to analyze the incidence of female breast cancer during the period and then to predict its trend from 2008 to 2015.

METHODSThe incidence data of breast cancer from 1998 to 2007 were sorted from National Cancer Registry Database, including 74 936 cases from urban areas and 8230 cases from rural areas, separately covering 164 830 893 and 55 395 229 person years. The crude incidence rates in urban and rural areas were calculated, and the age-standardized rate (ASR) was adjusted by World Segi's population composition. JoinPoint software was applied to analyze the 10 years' incidence trend and calculated the annual percentage of changing (APC), while Age-Period-Cohort Bayesian Model was used to fit the data and predict the incidence of breast cancer between 2008 and 2015.

RESULTSFrom 1998 to 2007, the incidence of breast cancer in the urban cancer registration areas was 45.46/100 000 (74 936/164 830 893), whose ASR was 31.28/100 000. While in rural registration areas, the incidence and ASR was 14.86/100 000 (8230/55 395 229) and 12.13/100 000. The breast cancer incidence in urban and rural areas separately rose from 36.17/100 000 (3920/10 838 355) and 10.39/100 000 (436/4 197 806) in 1998 to 51.24/100 000 (11 302/22 057 787) and 19.61/100 000 (1475/7 522 690) in 2007. During the 10 years, the breast cancer incidence increased both in urban and rural areas, but the increase rate in rural incidence (6.3%) was more significant than it in urban areas (3.9%). Age-Period-Cohort Bayesian Model predicted that the breast cancer incidence would increase to 53.87/100 000 (185 585 new cases) in urban areas and 40.14/100 000 (132 432 new cases) in rural areas, respectively.

CONCLUSIONThe breast cancer incidence has been increasing annually both in urban and rural areas in China; and an annually increase number of new cases have been predicted.

OBJECTIVEBased on the data from National Cancer Registry between 1998 and 2007, to analyze the colorectal cancer incidence trend in China, and further to predict its incidence between 2008 and 2015.

METHODSWe picked up the incidence data of 111 281 cases of colorectal cancer in total from National Central Cancer Registry Database between 1998 and 2007, covering 446 734 668 person-year. The annual incidence rate of colorectal cancer both by area and gender were calculated; while the age standardized rate (ASR) was standardized by world's population age structure. The incidence trend was analyzed and the annual percentage change (APC) was calculated by JoinPoint software. Age-Period-Cohort Bayesian Model was applied to fit the colorectal cancer incidence trend in China between 1998 and 2007; and further to predict its incidence between 2008 and 2015.

RESULTSFrom 1998 to 2007, the colorectal cancer registered incidence was 24.91/100 000 (111 281/446 734 668), with the ASR at 17.67/100 000. The incidence in male population was 26.50/100 000 (60 015/226 508 545), with ASR at 19.90/100 000; and the incidence in female was 23.28/100 000 (51 266/220 226 123), with ASR at 15.73/100 000. In urban area, the male incidence rose from 23.29/100 000 (2617/11 237 967) in 1998 to 37.84/100 000 (8534/22 551 353) in 2007; while the female incidence increased from 21.75/100 000 (2357/10 838 355) to 31.34/100 000 (6913/22 057 787). And in rural areas, the male and female incidences rose from 10.36/100 000 (448/4 323 628) and 8.86/100 000 (372/4 197 806) in 1998 to 16.80/100 000 (1290/7 677 484) and 13.00/100 000 (978/7 522 690) in 2007 respectively. In this decade, the colorectal cancer incidence has increased both in urban and rural areas. In urban area, the male APC value was 5.5% and the female APC value was 4.0%; while in rural area, the male and female APC values were 6.0% and 4.3% respectively. After adjusted by age structure, the uptrend became gently; with the urban male and urban female APC values separately increased by 3.7%, 2.5% and 2.3%. The rural male APC value rocketed up by 8.4% after its inflection point in 2004. The Bayesian model predicted that the male and female colorectal cancer incidences would separately reach 33.92/100 000 (125 thousand cases) and 27.13/100 000 (93 thousand cases) in urban areas; and 13.61/100 000 (48 thousand cases) and 13.68/100 000 (45 thousand cases) in rural areas by year 2015.

CONCLUSIONThe colorectal cancer incidence in China has been increasing annually; and it will continue to rise in the next years.

OBJECTIVEBased on the registered esophageal cancer data from 1998 to 2007, to analyze the incidence of esophageal cancer during the period and then to predict its trend between year 2008 and 2015.

METHODSThe incidence data of esophageal cancer between 1998 and 2007 were sorted from National Cancer Registry Database. Data from forty selected registries were qualified and recruited in the study, including 86 427 cases in total, covering 446 734 668 person years. Crude incidence rates were calculated by area and gender. The standardized incidence rate was adjusted by World Segi's population composition. JoinPoint software was applied to analyze the 10 years' incidence trend and calculated the annual percentage change, while Age-Period-Cohort Bayesian Model was used to fit the data and predict the incidence between 2008 and 2015.

RESULTSBetween 1998 and 2007, the crude incidence rates among males and females in urban areas were separately 16.58/100 000 (28 207/170 131 309) and 7.14/100 000 (11 761/164 830 893), with standardized rates at 12.06/100 000 and 4.55/100 000, respectively. In rural areas, the crude incidence rates and the standardized rates were separately 51.98/100 000 (29 303/56 377 236) and 47.18/100 000 among males, and 30.97/100 000 (17 156/55 395 230) and 25.30/100 000 among females. During the ten years, the crude incidence trend of esophageal cancer among urban females decreased from 10.29/100 000 (1115/10 838 355) in 1998 to 6.29/100 000 (1387/22 057 787) in 2007. However, the crude incidence rate among rural males increased from 47.69/100 000 (2062/4 323 628) to 54.80/100 000 (4207/7 677 484) in the same period. And the rate among rural females and urban males did not change obviously. After adjusting population structure, in urban areas, the male incidence rate decreased by 2.1% annually and female incidence rate dropped by 7.5% annually. In rural areas, the female incidence rate fell by 1.3% annually, while the male incidence rate remained the same without significant changes. The prediction model estimated that there would be 134 474 new esophageal cancer cases diagnosed in year 2015, including 104 400 males and 30 074 females, while 52 506 cases came from urban areas and the other 81 968 cases were from rural areas.

CONCLUSIONThe esophageal cancer incidence showed a downtrend, especially among urban females. By year 2015, the threat of esophageal cancer will be alleviated.

OBJECTIVEBased on the cancer registry data during 1998 - 2007, to analyze the incidence of liver cancer in China and predict the trend of incidence of liver cancer between 2008 and 2015.

METHODSLiver cancer incidence data from cancer registry between 1998 and 2007 was collected, including a total of 115 417 cases, covering 446 734 668 person-year. We calculated the annual incidence rate of liver cancer by gender and area. Age-standardized rate (ASR) was calculated by the world's population age structure. JoinPoint software was applied to analyze the incidence trend and calculate annual percent change (APC). Age-Period-Cohort Bayesian Model was used to fit the incidence trend and predict the incidence trend between 2008 and 2015.

RESULTSFrom 1998 to 2007, according to the data from cancer registry, the liver cancer incidence was 25.84/100 000 (115 417/446 734 668), with the ASR at 18.82/100 000. In urban areas, the male incidence was 34.30/100 000 (58 353/170 131 309), with ASR at 24.99/100 000; while the female incidence was 12.33/100 000 (20 324/164 830 893), with ASR at 7.99/100 000. In rural areas, the male incidence was 48.56/100 000 (27 378/56 377 236), with ASR at 42.27/100 000; while the female incidence was 16.90/100 000 (9362/55 395 230), with ASR at 13.52/100 000. During the decade, in urban areas, the APC of male and female liver cancer incidence rates were separately 1.1% and -0.5%, with ASR at -0.5% and -1.9%; while in rural areas, the APC of male and female liver cancer incidence rates were separately 3.7% and 3.1%, with ASR at 1.9% and 1.3%. Age-Period-Cohort Bayesian Model predicted that in urban areas, the male and female incidence of liver cancer in 2015 would reach 30.73/100 000 (113 279 cases) and 10.44/100 000 (35 978 cases), with ASR at 23.70/100 000 and 7.21/100 000, respectively; while in rural areas, the incidence rates would increase to 51.67/100 000 (182 382 cases) and 15.03/100 000 (49 580 cases), with ASR at 39.80/100 000 and 10.45/100 000, respectively.

CONCLUSIONThe incidence of liver cancer will increase between 2008 and 2015, but its ASR will decrease slightly. In the near future, the number of new liver cancer cases will keep increasing. Liver cancer is still the dominant cancer and one key point for cancer prevention and control in China.

OBJECTIVETo investigate the clinical features, differential diagnosis and management of congenital stenosis of external auditory canal (CSEAC) with cholesteatoma.

METHODSThe clinical information for 10 cases of CSEAC with cholesteatoma was retrospectively reviewed.

RESULTSThe patients' ages ranged from 4.75 to 22 years (average 12 years). The diameter of the external auditory canal (EAC) was < 2 mm. All 10 ears had a history of postural fistulae or sinuses. Bone erosion of EAC was distinctly shown in high-resolution computed tomography (HRCT) of all cases, as well as soft tissue masses, which led to enlargement of the bony canals. All patients underwent canaloplasty; eight ears received hearing reconstructions at the same time. Cholesteatoma in EACs was confirmed during the operations, accompanied by compression and destruction of the post-superior and/or inferior bony wall. Postoperative pathologic examinations proved the diagnosis of cholesteatoma, and excluded any tissue of bronchial cleft cyst or fistula. After a follow-up 1 to 3 years, no recurrent cholesteatoma was found in any of the 10 cases. All reconstructed EACs were clean and smooth. The hearing levels in the eight ears that received hearing reconstructions improved 20 - 35 dBHL.

CONCLUSIONSIn CSEAC with cholesteatoma, the bony wall of EAC is most commonly involved. This involvement will lead to bone erosion of the EAC and may subsequently lead to the formation of postural or cervical sinuses. HRCT of temporal bone can show characteristic signs of soft tissue mass in EAC, with adjacent bone erosion.

Mitral regurgitation(MR)is a common valvular heart disease in China,the prevalence of which increases with age,and most patients present with a wide range of cardiac or non-cardiac comorbidities.Transcatheter mitral valve edge-to-edge repair(TEER)has become a guideline-recommended,safe and effective treatment option for patients with severe primary or secondary mitral regurgitation.With the rapid development of TEER technology in China,relevant devices have been developed and approved for clinical trials,including the self-designed and manufactured JensClip system,which adopts a unique slider locking design to realize the innovation of mitral clip locking mode.Here we reported a case of JensClip device in treatment of a patient with degenerative mitral regurgitation(DMR).

Transcatheter aortic valve replacement(TAVR)is currently one of the main therapeutic strategies for aortic valve disease.Preoperative imaging assessment is crucial for operation project planning and prevention of procedure-associated complications.Different from planar image reconstruction,3D printing technology can accurately depict the anatomical structure of the aortic root.It enables further assessment of operative risk and therapeutic strategy through in vitro simulation,especially for assessing the risk of coronary artery obstruction and planning interventional procedures.Here,we report on two patients who underwent a 3D printing aortic root anatomical simulation model,followed an by in vitro balloon dilatation/valve implantation test,to evaluate the risk of coronary artery obstruction suggested by CT angiography planar image reconstruction before TAVR.
