ABSTRACT

Although talus fractures are not common among foot and ankle injuries, their treatment is difficult because of their complications and poor prognosis. They can be treated conservatively or surgically, with a variety of treatment protocols. At present, the main strategy of surgical treatment is to use strong and effective fixation to restore anatomic structure of the talus and preserve blood supply to the talus as much as possible so that deformity can be avoided and early healing be facilitated. This paper reviews the difficulties and current situation, and summarizes principles and the latest progress in clinical treatment of talus fractures, hoping to provide useful references for the treatment.

ABSTRACT

Objective:To evaluate the Ganz approach in the internal fixation of Pipkin Ⅳ femoral head fracture.Methods:The data of 7 patients with Pipkin Ⅳ femoral head fracture were retrospectively analyzed who had been admitted to Department of Orthopaedics, Xijing Hospital from March 2013 to April 2019. They were 5 males and 2 females, aged from 23 to 66 years (average, 40.5 years). The time from injury to operation ranged from 5 to 13 days (average, 7.3 days). In all the 7 patients, the Ganz approach was adopted in the internal fixation with double-head compression screws for femoral head fracture and in the internal fixation with screws plus a reconstruction plate for acetabular fracture. Their operation time, intraoperative bleeding, fracture reduction, hip functional recovery and complications were recorded. The hip function was assessed by Harris hip score.Results:Their operation time ranged from 155 to 235 min (mean, 197.9 min) and their intraoperative bleeding from 450 to 765 mL (mean, 590.0 mL). This cohort was followed up for 12 to 86 months (mean, 34.4 months). According to the Letournel recommended criteria for reduction quality of acetabular fractures, anatomical reduction was achieved in 6 cases and satisfactory reduction in one; according to the Thompson-Epstein clinical and imaging evaluation, the reduction of femoral head fracture was excellent in 6 cases and good in one. Their Harris hip scores at the last follow-up ranged from 92 to 97 (mean, 93.0). Traumatic arthritis developed in one case which was still under observation and muscular vein thrombosis developed in the affected limb in 2 cases but was organized after standard treatment.Conclusion:In the treatment of Pipkin Ⅳ femoral head fracture, the Ganz approach can lead to good reduction quality and fine functional recovery of the hip.

ABSTRACT

Objective:To investigate the success rate, operation time and complications of ultrasound combined with X-ray-guided precise implantation of totally implantable access port (TIAP) in the chest wall.Methods:A total of 623 patients who underwent implantation of totally implantable venous access ports in the chest wall in Meizhou People's Hospital, China between January 2015 and August 2018 were included in this study. In group A ( n = 320), jugular or subclavian access ports were precisely implanted in the chest wall under the guidance of ultrasound combined with X-ray. During the surgery, color Doppler ultrasound was used to guide the puncture and a C-arm machine was used to locate the position of catheter tip. In group B ( n = 303), venous access ports were implanted using the conventional method. Subclavian vein puncture was performed using anatomic landmarks and the depth of catheterization was estimated by experience. The success rate of the first implantation, operation time, and complications (pneumothorax, hemothorax, catheter displacement, poor position of catheter tip, skin infection, and thrombosis) were compared between the two groups. Results:There were no statistical differences in baseline data between the two groups ( P > 0.05). The success rate of the first implantation in the group A was significantly higher than that in the group B [100% (320/320) vs. 93.06% (282/303), χ2 = 22.95, P < 0.01]. The operation time in the group A was significantly shorter than that in the group B [(26.48 ± 5.49) minutes vs. (35.51 ± 14.37) minutes, t = -10.25, P < 0.01]. In group A, 2 patients developed pneumothorax and healed after conservative treatment, 6 patients had thrombosis, and the incidence of complications was 2.5% (8/320). In group B, complications occurred in 67 patients, including pneumothorax in 9 patients, poor catheter tip position in 17 patients, thrombosis in 36 patients, and skin infection in 1 patient, and the incidence of complications was 22.11% (67/303). There was significant difference in the incidence of complications between the two groups ( χ2 = 56.53, P < 0.01). In group B, 6 out of 9 patients developing pneumothorax were healed after closed thoracic drainage, and 4 patients underwent a secondary surgery because of catheter displacement into the internal jugular vein. Conclusion:Precise implantation of venous access ports in the chest wall guided by ultrasound combined with X-ray has the advantages including 100% success rate of first precise implantation, few complications, short operation time, high comfort, safety and efficacy.

ABSTRACT

Objective:To investigate the in-stent thrombosis after carotid artery stenting revealed by optical coherence tomography (OCT) and its possible risk factors.Methods:Consecutive patients with carotid artery stenosis underwent carotid artery stenting and intraoperative OCT between January 2015 and December 2019 were selected through the Stroke Registration Center of the Second Affiliated Hospital of Guangzhou Medical University and Nanjing Stroke Registry Program. The clinical characteristics of the patients were recorded, OCT images were analyzed, and postoperative in-stent thrombosis was observed. At the same time, OCT image features such as plaque calcification, thin fiber cap, stent apposition, plaque prolapse and microdissection were collected. The risk factors for in-stent thrombosis were analyzed.Results:A total of 63 patients were included. OCT showed that 17 of them (23.3%) had in-stent thrombosis. Perioperative vascular events occurred in 4 patients due to in-stent thrombosis. One of them was more serious. There were no perioperative vascular events in the in-stent non-thrombosis group. Multivariate logistic regression analysis showed that microdissection was an independent risk factor for in-stent thrombosis after carotid artery stenting (odds ratio 5.439, 95% confidence interval 1.102-26.837; P=0.038). Conclusions:OCT can reveal in-stent thrombosis after carotid artery stenting, which was associated with perioperative vascular events, and microdissection was one of the possible causes of in-stent thrombosis.

ABSTRACT

OBJECTIVE@#To investigate the effect of other gene mutations outside the fusion gene on the first complete remission (CR) induced by one course of induction chemotherapy in patients with core binding factor-associated acute myeloid leukemia (CBF-AML).@*METHODS@#DNA was extracted from bone marrow or peripheral blood samples of newly diagnosed CBF-AML patients admitted to the Hematology Department of the Second Hospital of Shanxi Medical University from January 2015 to January 2019. Next-generation sequencing was used for detection of 34 kinds of hematologic malignancy-related gene mutations in patients with CBF-AML, the effect of related gene mutations on the first complete remission (CR) rate in one course of induction chemotherapy was analyzed by combineation with clinical characteristics.@*RESULTS@#34 kinds of genes in bone marrow or peripheral blood of 43 patients were detected by high throughput sequencing and the gene mutations were detected in 16 out of 34 genes. The mutation rate of KIT gene was the highest (48.8%), followed by NRAS (16.3%), ASXL1 (16.3%), TET2 (11.6%), CSF3R (9.3%), FLT3 (9.3%), KRAS (7.0%). The detection rates of mutations in different functional genes were as follows: genes related with signal transduction pathway (KIT, FLT3, CSF3R, KRAS, NRAS, JAK2, CALR, SH2B3, CBL) had the highest mutation frequency (72.1% (31/43); epigenetic modification gene mutation frequency was 30.2% (13/43), including ASXL1, TET2, BCOR); transcriptional regulation gene mutation frequency was 7.0% (3/43), including ETV6, RUNX1, GATA2). Splicing factor related gene mutation frequency was 2.3% (1/43), including ZRSR2). The CR rate was 74.4% after one course of induction chemotherapy. At first diagnosis, patients with low expression of WT1 (the median value of WT1 was 788.9) were more likely to get CR (P=0.032) and the RFS of patients who got CR after one course of induction chemotherapy was significantly longer than that of patients without CR [7.6 (2.2-44.1) versus 5.8 (1-19.4), (P=0.048)]. The rate of CR in the signal transduction pathway gene mutation group was significantly lower than that in non-mutation group (64.5% vs 100%) (P=0.045), while the level of serum hydroxybutyrate dehydrogenase (HBDH) was significantly higher than that in non-mutation group [(418 (154-2702) vs 246 (110-1068)] (P=0.032). There was no difference in CD56 expression between the two groups (P=0.053), which was limited to the difference between (≥20%) expression and non-expression. (P=0.048).@*CONCLUSION@#CBF-AML patients with signal transduction pathway gene mutation are often accompanied by high HBDH level and CD56 expression, moreover, the remission rate induced by one course of treatment is low.

ABSTRACT

Unraveling the genetic basis of medicinal plant metabolism and developmental traits is a long-standing goal for pharmacologists and plant biologists. This paper discusses the definition of molecular genetics of medicinal plants, which is an integrative discipline with medicinal plants as the research object. This discipline focuses on the heredity and variation of medicinal plants, and elucidates the relationship between the key traits of medicinal plants(active compounds, yield, resistance, etc.) and genotype, studies the structure and function, heredity and variation of medicinal plant genes mainly at molecular level, so as to reveal the molecular mechanisms of transmission, expression and regulation of genetic information of medicinal plants. Specifically, we emphasize on three major aspects of this discipline.(1)Individual and population genetics of medicinal plants, this part mainly highlights the genetic mechanism of the domestication, the individual genomics at the species level, and the formation of genetic diversity of medicinal plants.(2)Elucidation of biosynthetic pathways of active compounds and their evolutionary significance. This part summarizes the biosynthesis, diversity and molecular evolution of active compounds in medicinal plants.(3) Molecular mechanisms that shaping the key agronomic traits by internal and external factors. This part focuses on the accumulation and distribution of active compounds within plants and the regulation of metabolic network by environmental factors. Finally, we prospect the future direction of molecular genetics of medicinal plants based on the rapid development of multi-omics technology, as well as the application of molecular genetics in the future strategies to achieve conservation and breeding of medicinal plants and efficient biosynthesis of active compounds.

ABSTRACT

@#The apical displacement of tricuspid valve leaflets complicated with significantly enlarged, thin and fibrotic wall of the right ventricle is prone to dysfunction of right heart. Therefore, the myocardial protection for the right ventricle is important. Based on the pathological changes, an algorithm of perioperative myocardial protection strategy is summarized. Firstly, we should clearly know that the right ventricular myocardium with severe lesions is much different from the unimpaired myocardium, because it is now on the margin of failure; secondly, right heart protection should be regarded as a systematic project, which runs through preoperative, intraoperative and postoperative periods, and requires close collaboration among surgeons, perfusionists, anesthesiologists and ICU physicians. In this article, we try to introduce the systematic project of the right heart protection, in order to improve the outcome of this population.
