With the progress of science technology,the 3D technology has raised comprehensive attention for its application value in medical field,especially in the orthopedic field.It has been mainly used before complicated orthopedic surgeries,and several studies have focused on 3D duplicated materials used in the treatment of bone defect.However,there are seldom studies about the 3 D technology used during surgeries,such as whether it is possible to 3D print internal fixation materials of bone fracture (the materials have biodegradability and excellent biomechanical characteristics),which can not only promote the healing of fracture,but also reduce the pain of second surgery for the patient.This paper reviews and summarizes the exploration of foreign and domestic scholars about the application value of 3 D printing technology used in complicated bone fracture,and proposes a forecast to the developing trend of the technology used in future orthopedic surgeries.

Objective To investigate the relationship between children history of asthma and family history of asthma.Methods Three thousand and five hundred outpatients of asthma children were selected as investigation subjects.Family history of asthma was investigated in the form of questionnaire,and analyzed them from whether or not having family history of asthma,the first and second degree relative having family history of asthma.Results There was no family history of asthma in 1 659 cases(47.4%) and while 1 841 cases had family history of asthma(52.6%).The children who had family history of asthma were slightly more than those who had no family history of asthma.Among the 1 841 cases with family history of asthma,the first degree relatives with family history of asthma were more than those second degree relatives with fa-mily history of asthma.The incidence rate of relatives with family history of asthma on mother′s side was 59.9%,and the incidence rate of the father′s relatives was 40.1%.The incidence rate of mother′s relatives was higher than that of father′s relatives(P

Tumor genesis and development often result from deregulation of important biological pathways at the gene expression level. Although there has been much work focused on searching gene sets using gene expression data or other prior information, proper statistical testing of the gene sets is still an open question. Most studies have expanded the testing method of a single gene into the gene sets. Parametric statistical analysis of gene sets ( p-SAGE ) was presented for determining the significant gene sets or pathways associated with a phenotype of interest. The method was applied to brain tumor experiments to identify many gene sets. Some of the newly discovered gene sets were related to signal transduction and immunity. This simple and effective method gives useful biologically meaningful results.

The imaging findings of pelvic lipomatosis as confirmed by operation and pathology were examined in 1 case and two follow-up asymptomatic cases retrospectively analyzed.The imaging findings included a compressed and deformed bladder with a superior displacement.Its shape was like an inverted tear and pear in coronal view and a banana in sagittal view.Bilateral ureters were both compressed with a medial deviation.And bilateral ureters were dilated with hydronephrosis in 1 case.Rectum and sigmoid were both compressed and became narrowed.The clinical manifestations included frequent urination , urgent urination , urination pain, dysuria, constipation, nausea, vomit and fever in 1 case while another 2 cases stayed asymptomatic.

Objective To explore the occurrence of diaphragmatic muscle fatigue(DMF) in children with pneumonia and its relationship with respiratory failure.Methods One hundred and twenty-six cases of pneumonia(pneumonia group) and 60 healthy children(healthy control group) were selected,and 2K-V1 type intelligence electric impedance respirograph was used to measure diaphragmatic function of the children in both groups to find if the ribcage-abdomen motion was synchronic and to calculate M levels.The abdomen impedance values as X-axis were calculated,which were regarded,and the chest impedance values as Y-axis were calcaulated,which described two-dimensional chart of ribcage-abdomen motion curve and the ? angle which was between connection of maximum X value to the smallest X value and the X-axis were calculated.According to the changes of chest-abdominal curve in one-dimensional chart and the changes of M value and ? angle,the degree of the diaphragmatic muscle fatigue was judged.Results There were 98 cases of DMF in the 126 children with pneumonia,and 68 cases of which were type Ⅰ DMF,and 30 cases were type Ⅱ DMF.One-dimensional chart showed contradictory chest-abdominal respiratory motional curve,and two-dimensional chart moved in a clockwise direction.M value was(46.1?8.4)%,? angle was(136.7?12.0) degrees in children with type Ⅰ DMF;One-dimensional chart showed that the peak value of chest-abdominal respiratory motional curve dislocates,and two-dimensional chart moved in a counter-clockwise direction.M value was(17.2 ? 3.2)%,? angle was(48.2 ? 9.5) degrees in children with type Ⅱ DMF;the control group had M value(4.3 ? 1.0)%,? angle was(31.7 ? 5.2) degree.There were significant differences in M value and ? angle between type Ⅰ DMF children,type Ⅱ DMF children and healthy children(Pa

Objective To investigate the applied value of computed radiography(CR) system in intravenous pyelography in children.Methods Intravenous pyelography were carried out by CR and traditional intensifying screen/film in 45 children respectively.The diagnostic specificity between CR and traditional intensifying screen/film was compared.Results Urinary system in children could be displayed well by CR,the quality of CR films was ensured.The diagnostic corresponding rate was 86.7% and 59.1% by CR and traditional intensifying screen/film respectively.Conclusion CR is of significance value in diagnosis of urologic diseases in children.

Objective:To discuss the curative effect of bifid triple viable capsules in the patients after laparoscopic cholecystecto-my ( LC) . Methods:Totally 100 cases of patients with LC were selected and divided into the observation group and the control group at random. The patients in the two groups underwent LC under the general anesthesia, and were given routine medical treatment after the operation. The patients in the observation group were additionally given bifid triple viable capsules, 630mg per time, twice a day for 1 week as the treatment course. The changes in the occurrence of diarrhea, alteration of intestinal flora and plasma D-lactic acid of the patients and drug adverse reactions in the two groups were observed and compared after the medical treatment. Results:One week after the operation, the occurrence of diarrhea and alteration of intestinal flora of the patients in the observation group were lower than those in the control group (P<0. 05), and compared with those before the treatment, the plasma D-lactic acid levels of the patients in the two groups were declined (P<0. 05 or P<0. 01), and the declining rate in the observation group was much higher than that in the control group (P<0. 05). Totally 3 and 5 cases of drug adverse reactions were appeared in the observation group and the control group, respectively with no significant difference (P>0. 05). Conclusion: The application of bifid triple viable capsules in the pa-tients after LC can effectively reduce the plasma D-lactic acid levels, occurrence of diarrhea and alteration of intestinal flora with prom-ising security, which is good for the postoperative recovery of the patients.

Objective To study the therapeutic effect of EUS-guided rendezvous (EUS-RV) when ERCP failed in patients with malignant obstructive jaundice. Methods 12 cases of malignant obstructive jaundice patients were underwent EUS-RV after unsuccessful ERCP. The operation success rate, liver function recovery 1 week and 1 month after operation, complication rates, hospital stay and patient survival were observed. Results All 12 patients were successfully operated and placed stents by endoscopic ultrasound puncture following by ERCP: 8 patients by the stomach, 4 patients by duodenum, the operation success rate was 100.00%; There were significant difference between the liver function recovery of preoperative and postoperative one week or postoperative one week and postoperative one month (P < 0.05). 1 bleeding occurred and were improved after conservative treatment, the complications rate was 8.33%; the hospital stay was (20.68 ± 5.76) d; the average survival time of patients was 224 d. Conclusion EUS-guided rendezvous may be the alternative treatment due to the diminutive trauma and good effect when ERCP failed in patients with malignant obstructive jaundice.

Objective To explore the role of endogenous and exogenous β-glucuronidase( β-G) in the development of primary common duct stones.Method Using modified Fishman method to test the activities of the endogenous and exogenous β -G in 35 patients with primary common duct stones(experimental group) and 11 patients with cystic polypus (control group) respectively.Results The activities of endogenous β -G in the bile of experimental group and control group were (7859.1 ± 738.5 ),(2174.9 ± 348.4 ) U/L(P ＜0.01).While the activities of exogenous β-G in experimental group and control group were (6786.1 ±544.3),(1504.7 ±655.7) U/L (P ＜0.01).In experimental group,there were significant statistical differences in the activities of the exogenous β -G in the sample obtained on the day of operation and 7 days after operation from 13 cases with the acute inflammation [(8935.7 ± 845.9),(2176.1 ± 956.7) U/L]and from 22 cases with the chronic inflammation [(5137.2 ±540.7),(1838.8 ±733.3) U/L],and there were significant higher in the activities of the exogenous β -G in the sample obtained on the day of operation from the acute inflammation compared to those from the chronic inflammation (P ＜ 0.05 ).Conclusions There is obvious correlation between either endogenous or exogenous β -G with primary common duct stones.And the endogenous β -G might be one of the fundamental cause in the development of primary common duct stones.
