This study aimed to investigate viral infections and the prevalence of influenza-like illness (ILI) in Shijiazhuang, China, in 2011 and to provide a scientific basis for the diagnosis and control of respiratory tract infections. Throat swab specimens were collected from 483 cases of ILI who were outpatients in the influenza surveillance sentinel hospitals in Shijiazhuang between January and December 2011. All specimens were examined by multiplex RT-PCR for the following 15 respiratory tract viruses: adenovirus (ADV), human rhinovirus (HRV), human parainfluenza virus (PIV types 1-4), influenza virus A (FluA), influenza virus B (FluB), human enterovirus (HEV), respiratory syncytial virus (RSV-A and -B), human metapneumovirus (HMPV), human coronavirus (HCoV-229E/NL63 and -OC43/HKU1), and human bocavirus (HBoV). Among the 483 cases of ILI, 214 (44.31%) were positive for viruses, including ADV (8.7%), HEV (8.7%), RSV-A (8.07%), HRV (7.45%), FluA (5.38%), HCoV-OC43/ HKU1 (2.9%), PIV-3 (2.9%), HMPV (1.86%), PIV-1 (1.24%), HCoV-229E/NL63 (1.04%), PIV-2 (1.04%), HBoV (0.83%), and FluB (0.41%). Twenty-six (5.38%) of all cases were co-infected with two or more viruses, most commonly HEV/HRV with other viruses. Cases of viral infection were detected throughout the year, with peaks in January and February. ADV and HRV were detected throughout almost the whole year without obvious seasonality. HEV was detected between April and November, with a peak of prevalence in summer and autumn. FluA and FluB reached epidemic levels mainly in winter and spring. All cases of RSV were identified to be subtype A. PIV infection was mainly caused by PIV-3. The positive rate of HCoV-OC43/HKU1 infection was significantly higher than that of HCoV-229E/NL63. The leading five viruses that resulted in ILI Shijiazhuang in 2011 were HEV, ADV, RSV-A, HRV, and FluA, and these viruses have different epidemiological features.

Objective: To evaluate the impact of coronavirus disease 2019 ( COVID-19 ) prevention and control measures in Huzhou on influenza epidemic strength and characteristics in 2020, so as to provide reference for formulating influenza prevention measures. Methods: Using the influenza surveillance data of the national influenza sentinel surveillance system from January 2015 to July 2020, the seasonal characteristics of influenza epidemic were analyzed, the proportion of influenza-like illness cases ( ILI% ) and the positive rate of influenza virus in January to July of 2020 were compared with those of the same period in 2015-2019, in order to evaluate the impact of COVID-19 prevention and control measures. Results : The ILI% and the positive rate of influenza virus in Huzhou were 3.90% and 15.32% during 2015-2019, while were 4.41% and 12.63% from January to July of 2020. The trends of ILI% during 2015-2019 fluctuated similar, but continued to drop since January 2020. The positive rate of influenza virus peaked from December to March in 2015-2019, also peaked from December 2019 to January 2020, but decreased to 0 in March. ILI% was positively correlated with the positive rate of influenza virus ( r=0.682, P<0.05). The growth rates of ILI% from January to July 2020 were 4.75%, -11.27%, 0.68%, 19.84% and 0.92%, compared with the same period of 2015-2019, respectively. The growth rates of ILI% in January 2020 were much higher ( >57.00% ) and from April to July were much lower ( <-33.00% ) . The growth rates of influenza virus positive rate from January to July 2020 were -47.96%, -36.53%, -3.44%, -35.92% and -39.37%, compared to the same period of 2015-2019, respectively. The growth rates of influenza virus positive rate in January 2020 were much higher ( >11.00% ) and from February to March were much lower ( <-61.00% ). Conclusion Since COVID-19 prevention and control measures were implemented in January 2020 in Huzhou, the ILI% and the positive rate of influenza virus in sentinel hospitals decreased significantly.

OBJECTIVETo explore the influence of conventional metal materials in oral cavity on brain magnetic resonance imaging (MRI).

METHODSFour kinds of metal materials (metal ligature wire, forging hard and slotless denture, casting nichrome denture, casting copper alloy denture) in oral cavity were scanned through MRI. FSE sequence T1 weighted imaging (FSE T1), EPI diffusion-weighted imaging (DWI) sequence of ordinary, Propeller DWI imaging were used.

RESULTSIn FSE T1 sequence, metal ligature wire and forging hard and slotless denture produced serious false image, casting nichrome denture produced moderate false image, casting copper alloy denture produced only little false image. In EPI DWI sequence, obvious magnetic-sensitive false image were produced in the dissection tissue of the brain by metal ligature wire. While in Propeller DWI sequence, magnetic-sensitive false image were greatly reduced and satisfactory images were formed.

CONCLUSIONDifferent metal materials in oral cavity have different influence on the MRI. The false images produced by different metal materials are closely related to the type of the material. Magnetic-sensitive false images can be eliminated by Propeller DWI technique.

OBJECTIVETo study the clinical and pathological features, diagnosis, therapy and prognosis of primary small intestine malignant tumor.

METHODSA retrospective analysis was performed on the clinical data from the 120 cases of primary small intestine malignant tumor.

RESULTSAbdominal pain, gastrointestinal bleeding, anemia, abdominal mass and jaundice were the main clinical features. The pathology was confirmed by abdominal X-ray, gastrointestinal barium, CT, MRI, endoscopy and surgical exploration. Most tumors originated in the duodenum (54.1%), and adenocarcinoma (55.8%) was the main pathological type. The median survival time of the patients was 19.2 months and the 1-year survival rate was 55.4%. Chemotherapy did not seem to significantly improve the 1-year survival rate of the patients (P=0.842).

CONCLUSIONPrimary small intestine malignant tumors lack specific clinical manifestations and surgical resection should be performed as early as possible.

OBJECTIVETo discuss the therapeutic effects of the atlantoaxial pedicle screw system fixation in treatment of atlantoaxial instability.

METHODSFrom June 2003 to March 2010, 32 patients with atlantoaxial instability were treated by atlantoaxial pedicle screw system fixation, included 21 males and 11 females wiht an average age of 42.5 years old ranging from 28 to 66 years. Among them, 18 cases were odontoid process fractures, 7 were congenital dissociate odontoid process, 4 were Jefferson fracture combined with odontoid fracture, 3 were rheumatic arthritis causing atlantoaxial instability. All patients suffered from the atlantoaxial subluxation and atlantoaxial instability. The JOA score ranged from 4 to 14 (means 9.1 +/- 0.3) before operation. The patients had some image examination including the X-ray of cervical vertebrae (include of dynamic position film), spiral CT 3D reconstruction and/or MRI. The position of pedicle screw system implantation,the angle of pedicle screw system implantation and screw length were measured. Operating skull traction. Operation undewent general anesthesia, implanted the pedicle screw, reduction and bone fusion under direct vision. The bone was fixated between posterior arch of atlas and lamina of axis by the lateral combination bended to posterior.

RESULTSOne hundred and twenty-eight atlantoaxial pedicle screws were implanted in 32 patients. No patient had the injure of spinal cord, nerve root and vertebral artery. All patients were followed-up from 6 to 48 months (averaged 16 months). After operation, the JOA score ranged from 11 to 17 (averaged 15.9 +/- 0.2), improvement rate was 86.1%. The fracture of odontoid process were healing completely. All fusion bone were combinated. The internal fixation wasn't loosening and breaking.

CONCLUSIONThe atlantoaxial pedicle screw system fixation was effective method to treat atlantoaxial instability. The method had many advantages, such as provide rigid and short segment fixation, safe and simple, high fusion rate. The method was worth in clinical application.

OBJECTIVETo analyze the surgical treatment result and clinical characteristics of hilar cholangiocarcinoma in order to improve the rate of early diagnosis and radical resection.

METHODSBetween 1986 and 2004,84 hilar cholangiocarcinoma patients underwent surgery, and their data were retrospectively reviewed.

RESULTSAccording to the Bismuth-Corlette staging system, 7 were type I, 18 type II, 22 type II a, 12 type IlI b, 20 type IV and 5 unclassified. 32 patients (38.1%) had had the history of operation for cholelithiasis before or were found to have cholelithiasis simultaneously at the time of diagnosis. The rate of making correct diagnosis by ultrasound, CT and MRCP was 71.4% , 84.0% and 91.4% , respectively. Of these 84 patients, 24 (28.6%) underwent radical resection, 14 (16.7%) palliative resection and 30 (35.7%) only internal or external drainage, while 16 patients was found to have contraindication for any further surgical intervention. The overall operation rate was 81.0% (68/84) with a radical resection rate of 35.3% (24/68). The 1-, 3- and 5-year survival rates was 70.8%, 50.0% and 20.8% in the radical resection group, and 50.0%, 21.4% and 0 in the palliative resection group, respectively. There was a statistically significant difference in the survival between two groups. Whereas in the internal or external drainage group, the 1-, 3- and 5-year survival rates was 20.0% ,10.0% and 0. All of the patients who did not undergo surgical intervention died within one year.

CONCLUSIONCholelithiasis may play an important role in the pathogenesis of hilar cholangiocarcinoma. Early diagnosis and radical resection are two important factors to improve the prognosis of hilar cholangiocarcinoma. Skeletonization of hepatoduodenal ligament with partial liver resection can improve the rate of radical resection for hilar cholangiocarcinoma.

OBJECTIVESTo investigate the expression of P120 catenin in pancreatic carcinoma and to explore the association between P120 catenin gene polymorphism at T755G position and pancreatic carcinoma.

METHODSThe expression of P120 catenin in 52 cases of pancreatic carcinoma and normal pancreatic tissues on the mRNA and protein levels were evaluated by RT-PCR and Western Blot methods respectively. P120 catenin gene polymorphism at T755G position of in 52 patients and 60 healthy controls were examined by PCR-restriction fragment length polymorphism (PCR-RFLP) technique.

RESULTSThe mRNA and protein expressions of P120 catenin in pancreatic carcinoma tissues were significantly lower than normal pancreatic tissues (P=0.000, P=0.002). Reduced expression of P120 catenin mRNA was significantly correlated with differentiated (P=0.033), lymph node metastasis (P=0.004), vascular invasion (P=0.022), and pTNM stage (P=0.003). Additionally, there were significant difference of P120 catenin gene polymorphism genotypes and alleles at T755G position between patients and healthy controls (P=0.008, P=0.016). The GG genotype of P120 catenin gene was associated with higher risk of incidence for pancreatic carcinoma compared with the TT genotype (OR=2.765, 95%CI=1.312-3.958).

CONCLUSIONSThe reduced expressions of both P120 catenin mRNA and protein in pancreatic carcinoma suggest its association with pancreatic carcinoma development. Polymorphism of P120 catenin gene at T755G situation might be a risk factor for pancreatic carcinoma, and it may be used to diagnosis and prevent pancreatic carcinoma early.
