Objective To investigate the disease categories of the upper alimentary tract and the ratio of Hp infection in countryside children. Methods 96 children with complaint in upper digestive tracts underwent gastro-scope and in each patient,a piece of mueosal tissue in sinus ventrieuli was taken out to perform Hp urase test. Results All of the 96 children were detected abnormal including chronic superficial gastritis (n = 63), ulcer of duodenal bulb(n = 13) ,enteritis of duodenal bulb(n =7) ,gastritis with bile reflux(n =4) ,erosive gastritis(n =2) ,ascariasis (n = 6), aneylestomiasis(n = 3). The positive rate was 100%. 49/96 (51%) were positive in Hp test, including 36/ 63(57.1%) of chronic gastritis ,10/13(76.9%) of ulcer of duodenal bulb,2/7 (28.6%) of enteritis of duodenum. Hp were positive in 11 (35.5%) in the group with age range from 3 to 6 years old and positive in 38 (58.5%) in the group with age range from 7 to 12 years old. Conclusion Chronic superficial gastritis and ulcer of duodenal bulb were the main findings in gastrescopy in children with a upper digestive tract complaint. Hp infection ratio was highest in patients with ulcer of duodenal bulb in our study, and followed by the chronic gastritis. And the infection rate in-creased with the age increased.

Objective To evaluate whether there is a correlation among plasma levels of procalcitonin (PCT),N-terminal pro-brain natriuretic peptide (NT-pro-BNP)and cardiac troponin T (cTnT)in patients with sepsis,as well as significance to prognosis of patients.Methods 48 patients with sepsis who were admitted to the intensive care unit of a hospital between September 2014 and March 2015 were chosen for study,patients were divided into severe and mild sepsis groups according to the disease condition,plasma levels of PCT,NT-pro-BNP,and cTnT were de-tected,mortality of patients were analyzed statistically,relation between plasma levels of PCT,NT-pro-BNP,cT-nT and patients’death were compared.Results The plasma levels of PCT,NT-pro-BNP and cTnT in severe sepsis group were significantly higher than those in mild sepsis group (all P <0.05);mortality of mild sepsis group was significantly lower than that of severe sepsis group (10.53% vs 41.38%,P <0.05);Levels of PCT,NT-pro-BNP and cTnT levels in died patients were all higher than surviving patients (all P <0.05);levels of PCT and NT-pro-BNP,NT-pro-BNP and cTnT were positively correlated respectively (rs = 0.337,P <0.05;rs =0.456,P =0.001, respectively ),while PCT was not significantly correlated with cTnT.Plasma levels of PCT,NT-pro-BNP,and cTnT were all correlated with the prognosis of patients (P <0.05),and is helpful for judging the prognosis of pa-tients,combination of three indexes had better prognostic value for the prognosis.Conclusion Combination detec-tion of plasmid levels of PCT,NP-pro-BNP,and cTnT can assess the severity of infection in patients with sepsis, and preliminarily judge the prognosis of patients with sepsis.

ObjectiveTo observe the effect of Ornidazol on acute pericoronitis of wisdom tooth (PWT).Methods125 patients with PWT were randomly divided into the experiment group (63 cases, treated with Ornidazol) and control group (62 cases, treated with Metronidazole). The curative effect was observed when teeth extracted.ResultsThe effective rate of the experiment group was 95.2%, that of control group was 82.2%. There was a significant difference between two groups (P<0.05).ConclusionOrnidazol has an obvious effect on acute PWT.

ObjectiveTo observe the effect of Nd∶YAG laser combined with enamel cement on dentine hypersensitiveness (DH).Methods120 DH cases (totally 182 teeth) were randomly divided into two groups. The experiment group (92 teeth) was treated with Nd∶YAG laser and enamel cement. The control group (90 teeth) was only treated with Nd∶YAG laser.ResultsEffective rates of the experiment group at the moment of treatment, 3 months and 6 months after treatment were 97.8%, 96.7% and 90.2 % respectively, and that of the control group were 95.6%, 91.1% and 84.4%. There was a significant difference between two groups (P<0.05).ConclusionNd∶YAG laser combined with enamel cement has an obvious effect on DH.

Objective To observe the role of Osterix in controlling bone volume in vertebral body and to investigate the possible mechanism .Methods X-ray radiology ,micro CT and HE staining were used to evaluate the change of bone volume in both Osterix knockout and transgenic mice .TRAP staining was used to assess the activity of osteoclasts and immunohistochemistry was used to examine the expression level of RANKL .Results No obvious changes were found in Osterix transgenic mice ,while X-ray examina-tion ,micro CT and HE staining showed that the bone density and bone volume in the lumbar vertebral body increased significantly in OSX null mice 12 weeks after birth .TRAP staining showed that the number of osteoclasts decreased in OSX null mice .IHC re-vealed that the expression level of RANKL was down-regualted in OSX null mice .Conclusion Osterix play an important role in controlling bone volume of vertebral body in mice .

OBJECTIVETo investigate the clinical value of three-dimensional (3D) laparoscopic cholecystectomy in the treatment of complicated gallstone disease.

METHODSFrom March 2014 to March 2015, 46 patients underwent cholecystectomy for complicated gallstone disease under 3D laparoscopy (3D group) and 43 received 2D laparoscopic cholecystectomy (2D group). The surgical data including the operative time, intraoperative blood loss, the rate of conversion to open laparotomy, recovery time of postoperative bowel motion and hospital stay were compared between the 2 groups.

RESULTSLaparoscopic cholecystectomy was successfully completed in 43 patients in 3D group and in 39 patients in 2D group, and the rates of conversion to open laparotomy were similar between the two groups (P>0.05). The median operation time was significantly shorter in 3D group than in 2D group (50.5∓15.2 vs 65.4∓18.1 min, P<0.05), and the median volume of intraoperative blood loss was significantly smaller in 3D group (34.1∓13.6 vs 44.5∓22.3 mL, P>0.05). No significant differences were found in the recovery time of postoperative bowel motion and postoperative hospital stays between the two groups (P>0.05).

CONCLUSION3D laparoscopy, which provides three-dimensional vision with a good sense of depth to allow precise surgical manipulation, can shorten the operation time and reduce the rate of conversion to open laparotomy for patients undergoing 3D laparoscopic cholecystectomy for complicated gallstone disease.

Model informed precision dosing (MIPD) is a new concept to guide precision dosing for individual patient by modeling and simulation based on the available information about the individual patient, medications and the disease. Compared to the empirical dosing, MIPD could improve the efficacy, safety, economics and adherence of the pharmacotherapy according to the individual's pathophysiology, genotyping and disease progression. This consensus report provides a brief account of the concept, methodology and implementation of MIPD as well as clinical decision supporting systems for MIPD. The status and future advancing of MIPD was also discussed to facilitate the appropriate application and development of MIPD in China.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
