Objective To investigate the surgical method and clinical curative results of acetabulum top compression fractures with sea gull sign. Methods Data of 14 patients who had acetabulum top compression fractures with sea gull sign were retrospectively analyzed and were accepted surgical therapy and followed up. There were 5 females and 9 males, aged from 28 to 71 years (average, 49.9 years). The pre-operative time was from 4 to 14 days (average, 9 days). Letournel-Judet fracture classifica-tion:eight cases for the anterior column+posterior semi-transverse, six cases for a simple anterior column. Three patients with lum-bar compression fracture, two patients with tibial plateau fracture, one patient with multiple rib fractures. All patients were accept-ed open reduction and bone graft and internal fixation through ilioinguinal approach or ilioinguinal approach+Kocher-Langenbeck approach. The quality of fracture reduction was assessed according to the Matta reduction criterion after operation. The hip func-tion was evaluated according to Matta. Results 14 patients were followed up from 6 to 60 months (average, 36 months). All pa-tients reached bone healing;healing time was from 3 months to 4 months (average, 3.4 months). According to the Matta reset stan-dard after operation, there were 6 excellent cases, 5 good cases, 2 fair cases, 1 poor case, the excellent and good rate was 78.5%(11/14). The Matta was from 10 to 18 scores (average, 16.4 scores), 5 excellent cases, 5 good cases, 3 fair cases, 1 poor case, the ex-cellent and good rate was 71.4%(10/14). Traumatic arthritis occurred in 3 patients. Pain was serious in two patients and disap-peared after total hip joint replacement. Pain was mild for one patient and disappeared after accepted non steroidal painkiller. One patient had heterotopic ossification after operation, which was not treatmented because of no obvious symptom. Conclusion The appropriate operation time of acetabular roof compression fracture with sea gull sign was from 5 to 10 days after fracture, which was no more than two weeks had best. Through ilioinguinal approach or ilioinguinal approach+Kocher-Langenbeck approach, the articular surface could be reduced excellent and got sufficient bone graft. The clinical efficacy was satisfactory after operation.

The acute phase of ischemic stroke patients are often treated with both Chinese patent medicine:and western medicine therapies in clinical practice. This research included 27,678 cases of the acute phase of ischemic stroke came from 14 3A level hospitals. We collected data from patients with ischemic stroke who used both Chinese patent medicine and western medicine and were hopitalized within 14 days from hospital information system (HIS). Constructing complex network of Chinese patent medicine and western medicine were found to show scale-free network. Hierarchical structure of the core algorithm was used to analyze the characteristics of combined core Chinese patent medicine and western medicine in admission condition of "acute", "critically", and "general" of ischemic stroke acute phase patient within one day, 2-3 days, 4-7 days and 8-14 days. We found that the core Chinese patent medicine mainly used for activate blood and resolve stasis medicine, and phlegm eliminating brain refreshing medicine in all kinds of patients, but the phlegm eliminating brain refreshing medicine were used to reduce with time elapsing. The core western medicine mainly used for anti-platelet medicine, improve circulation medicine, neuroprotective medicine, anticoagulants medicine and dehydration medicine. The dehydration medicine as the core western medicine for critically patients within 14 days, but the patients for general admission as core western medicine within 3 days. The neuroprotective medicine was used to decreases after 7 days in hospital. Combination of Chinese patent medicine and western medicine were mainly for neuroprotective medicine + activate blood and resolve stasis medicine, and anti-platelet medicine + activate blood and resolve stasis medicine, and improve circulation medicine + activate blood and resolve stasis medicine. The phlegm eliminating brain refreshing medicine was mainly combined with neuroprotective medicine by urgent and general admission condition patients, and it was more combined with dehydration medicine by critically admission condition patients. This research found that the dynamic characteristics for the combination of Chinese patent medicine and western medicine of acute phase of ischemic stroke patients by big data analytics and complex networks modeling, and provide basis for acute phase of ischemic stroke patients, it provide basis for ischemic stroke treatment strategy making.

Background and purpose:Herpes zoster is a common adverse event associated with the use of bortezomib. The objective of this study was to evaluate the efifcacy of different therapeutic regimens of valacyclovir prophylaxis: continuously administration and intermittent administration. Methods: We retrospectively analyzed the efficacy, side effects, expense of valacyclovir and emotional states of 31 patients with multiple myeloma who received bortezomib and valacyclovir prophylaxis. Among them, 14 patients underwent continuously administration of valacyclovir, the other 17 patients underwent intermittent administration. Continuously administration was deifned as daily oral valacyclovir 600 mg without cessation during entire period of bortezomib treatment. Intermittent administration was deifned as patients received valacyclovir at a dose of 600 mg daily during chemotherapy, while discontinue valacyclovir at the intermission time of bortezomib treatment. Results: There were no herpes zoster in patients of 2 arms. Adverse events over grade 3 associated with valacyclovir were not observed. Intermittent administration of valacyclovir showed a superiority of economic beneift. The emotional status were depended on the therapeutic effects of multiple myeloma. For those relapsed or refractory patients, continuously administration of valacyclovir might aggravate depression and anxiety. Conclusion:Intermittent administration of valacyclovir at a dose of 600 mg daily appears to be an effective prophylaxis for herpes zoster in patients receiving bortezomib.

Magnesium based implants have the characteristics of bio-degradability, osteoconductive, and, regulatory strength. After the tissue has healed sufficiently, the burden of a second surgical procedure can be avoided. However, the degradation speed is so fast as to limit its clinical application. Hence, it is crucial for the biomedical magnesium alloys to be able to change their biodegradation behavior and speed. This paper reviews the degradability, biological activity and biocompatibility of magnesium and its alloys as orthopedic biomaterial in vitro and vivo to explore the possible way to modify the characteristics of its degradability, for the purpose of controllable degradation speed.

Objective Immune and inflammatory mechanisms could play a significant role in genesis or progression of interstitial lung disease and pulmonary arterial hypertension,especially in patients with connective tissue diseases.Specific antibodies may predict the occurrence of this condition.Methods The plasma of patients with systemic sclerosis(SSc)or mixed connective tissue disease(MCTD)were screened with enzyme linked immunoserbent assay(ELISA)and Western blotting using recombinant mocsin.The clinical data were recorded and pulmonary function tests(PFTs)were performed in 78 consecutive individuals in order to identify the difference in clinical manifestations between anti-mocsin positive group and negative group.Results Our results showed high titers of anti-mocsin antibodies in 21(53%)of 40 patients with SSc,and 15(39%)of 38 patient with MCTD.The presence of anti-moesin antibodies was significantly correlated with pulmonary involvement(ILD and PAH)in SSc and MCTD patiens(P=0.001).Comparing with the antibody negative group,the total lung capacity[(82±10)% vs(90±14)%,P=0.027),forced vital capacity [(76±13)% vs(85±17)%,P=0.040]and diffu-sing capacity of the lung for carbon monoxide[(58±16)% vs (72±23)%,P=0.014]of PFTs in anti-moesin antibodies positive group were noted to be significantly decreased(P＜0.05).Conclusion Specific antibodies to moesin is prevalent in patients with SSc and MCTD,so it may be an early predictor of pulmonary involvement in patients with SSc or MCTD.

Objective:To investigate the clinical effects of lacunar closure-assisted internal fixation in the one-stage treatment of Morel-Lavallée injury complicated with pelvic fracture.Methods:The 32 patients were retrospectively analyzed who had been treated for Morel-Lavallée injury complicated with pelvic fracture at Department of Orthopedic Trauma, Honghui Hospital Affiliated to Xi'an Jiaotong University from May 2018 to November 2020. They were 21 males and 11 females, aged from 18 to 58 years (average, 40.5 years). The injury was located at a unilateral hip in 20 cases, at bilateral hips in 6 cases, at low back in 4 cases, and at posterior thigh in 2 cases. The pelvic fractures were treated by open reduction and internal fixation while the Morel-Lavallée injuries by lacunar closure at the same time. Their wound healing, pelvic function and complications were observed regularly.Results:The hospital stay of 32 patients ranged from 14 to 28 days, averaging 19.2 days. The patients were followed up for 6 to 18 months (mean, 9.3 months). The area of Morel-Lavallée injury healed after one lacunar closure in 23 patients who obtained fine skin survival and no soft tissue necrosis or other complications; the wounds in the Morel-Lavallée injury area healed well after secondary lacunae closure in 4 patients. Superficial sensation of the skin decreased around the Morel-Lavallée injury area after wound healing in 3 patients. Wound fat liquefaction was found in the Morel-Lavallée injury area but responded to symptomatic treatment in one patient. A small amount of wound secretion found in the Morel-Lavallée injury area was cured also by symptomatic treatment in another patient whose bacterial culture was negative. All the fractures healed after 3 to 6 months (average, 3.9 months). At the last follow-up, the Majeed scores for the pelvic function ranged from 65 to 100 points, averaging 84.5 points.Conclusion:For Morel-Lavallée injury complicated with pelvic fracture, lacunar closure-assisted internal fixation can result in a satisfactory one-stage treatment.

The aim of the present study was to investigate the diagnostic value of the contrast-enhanced ultrasonography for gastrointestinal stromal tumors (GISTs). The conventional transabdominal ultrasonography and contrast-enhanced ultrasonography using an intraluminal contrast agent were performed in 66 cases. The different diagnostic value between conventional transabdominal ultrasonography and contrast-enhanced hydrocolon ultrasonography was compared, including the depiction ratio and location accuracy. The morpholpgical features of GISTs were observed. The sensitivity of the contrast-enhanced hydrocolon ultrasonography in the depiction of the GISTs (57/66, 86.4%) was higher than that of the conventional transabdominal ultrasonography(33/66, 50%, P<0. 05). Furthermore, the accuracy of the contrast-enhanced ultrasonography in the location of the GISTs (52/57, 91. 2%) was higher than that of the conventional transabdominal ultrasonography (13/33, 39. 4%, P<0. 05). The GISTs with higher or lower risk have different ultrasonic features. The contrast-enhanced ultrasonography was a more valuable diagnostic method for GIST than the conventional transabdominal ultrasonography.

BACKGROUNDSeasonal influenza epidemic occurs every year in Guangzhou, which can affect all age groups. Young children are the most susceptible targets. Parents can decide whether to vaccinate their children or not based on their own consideration in China. The aim of this study was to identify factors that are important for parental decisions on vaccinating their children against seasonal influenza based on a modified health belief model (HBM).

METHODSA cross-sectional study was conducted in Guangzhou, China. A total of 335 parents who had at least on child aged between 6 months and 3 years were recruited from women and children's hospital in Guangzhou, China. Each eligible subject was invited for a face-to-face interview based on a standardized questionnaire.

RESULTSUptake of seasonal influenza within the preceding 12 months among the target children who aged between 6 months and 36 months was 47.7%. Around 62.4% parents indicated as being "likely/very likely" to take their children for seasonal influenza vaccination in the next 12 months. The hierarchical logistic regression model showed that children's age (odds ratio [OR] =2.59, 95% confidence interval [CI]: 1.44-4.68), social norm (OR = 2.08, 95% CI: 1.06-4.06) and perceived control (OR = 2.96, 95% CI: 1.60-5.50) were significantly and positively associated with children's vaccination uptake within the preceding 12 months; children with a history of taking seasonal influenza vaccine (OR = 2.50, 95% CI: 1.31-4.76), perceived children's health status (OR = 3.36, 95% CI: 1.68-6.74), worry/anxious about their children influenza infection (OR = 2.31, 95% CI: 1.19-4.48) and perceived control (OR = 3.21, 95% CI: 1.65-6.22) were positively association with parental intention to vaccinate their children in the future 12 months. However, anticipated more regret about taking children for the vaccination was associated with less likely to vaccinate children within the preceding 12 months (OR = 0.21, 95% CI: 0.08-0.52).

CONCLUSIONSThe modified HBM provided a good theoretical basic for understanding factors associated with parents' decisions on their children's vaccination against seasonal influenza.

OBJECTIVETo investigate the effects of hydroquinone (HQ) on expression of Polymerase eta (Pol eta) and DNA damage in human hepatic cells (L-02), and to explore the role and possible mechanism of Pol eta involved in the process of DNA damage-tolerance.

METHODSAfter L-02 hepatic cells were exposed to HQ with various concentrations (0, 5, 10, 20, 40, 80 and 160 micromol/L) for 24 h, cell survival rate was detected by MTT assay; DNA impairment was detected by single cell gel electrophoresis (SCGE); Real-time fluorescent quantitative PCR and Western blotting methods were used to measure the expression of Pol eta at the mRNA and protein level in L-02 hepatic cells exposed to HQ with various concentrations (0, 5, 10, 20, 40, 80 and 160 micromol/L).

RESULTSMTT assay showed that HQ with concentrations from 0 to 80 micromol/L had little effect on the survival rate of L-02 (P>0.05); whereas the survival rate of the group of 160 micromol/Lwas significantly higher than that of the control (P<0.01) after being treated with HQ for 24 h; the higher dose of HQ presented, the more degrees of DNA damage were produced. It was found that HQ in a low concentration (1-80 micromol/L) could induce the expression of Pol eta which was in proportion to the increasements of HQ concentration; the expression levels of mRNA and protein were reached to the maximum when treated with 80 micromol/L; the expression of Pol eta decreased (the relative quantity values were 2.32 +/- 0.16 and 1.20 respectively) once the concentration of HQ exceeded 160 micromol/L as compared with the group of 80 micromol/L, but it was higher than that of the control.

CONCLUSIONThis study suggested that Pol eta might involve in the process of DNA damage-tolerance induced by HQ in the hepatic cells.
