ABSTRACT

Human epidermal growth factor receptor-2 (HER-2)-positive breast cancer has higher predilection to metastasize and invade other organs, leading to poor prognosis. The anti-HER-2 drugs, such as trastuzumab, pertuzumab, and trastuzumab emtansinehas, can remarkably prolong the disease free survival (DFS) of patients. However, frequent multidrug resistance, tumor recurrence and metastasis, and adverse reactions such as cardiotoxicity and gastrointestinal discomfort caused by adjuvant therapy are still challenges for the treatment of HER-2-positive breast cancer. The understanding of breast cancer in traditional Chinese medicine (TCM) has a long history. In thousands of years of inheritance and innovation, a standardized treatment system with TCM characteristics has been gradually formed, which shows unique advantages and significant curative effects in breast cancer treatment. The treatment principles of ''treatment based on syndrome differentiation'', ''treatment based on stages and types'', ''treatment according to individual conditions'', and ''treatment of different viscera and viscera based on the toxin and pathogen'' are closely related to the precise treatment concept. In view of the challenges in the treatment of HER-2-positive breast cancer, such as multidrug resistance, tumor recurrence and metastasis, cardiotoxicity, and gastrointestinal discomfort, this paper summarizes the characteristics of TCM in reversing the multidrug resistance, inhibiting tumor recurrence and metastasis, prolonging DFS, improving prognosis, reducing adverse reactions caused by adjuvant therapy, and improving the quality of life after breast cancer surgery according to the principles of reinforcing healthy Qi and eliminating pathogen, and treatment based on syndrome differentiation. This article is expected to serve as a reference for TCM treatment of HER-2 positive breast cancer.

ABSTRACT

Objective To evaluate the effect of extracorporeal membrane oxygenation (ECMO) on early allograft dysfunction (EAD) after heart transplantation. Methods Clinical data of 614 heart transplant recipients were retrospectively analyzed. All recipients were divided into the ECMO group (n=43) and non-ECMO group (n=571) according to postoperative application of ECMO. In the ECMO group, the conditions of recipients undergoing ECMO after heart transplantation were summarized. Perioperative status and long-term prognosis of recipients were compared between two groups. Results Among 43 recipients undergoing ECMO, 17 cases underwent thoracotomy due to bleeding, 10 cases of infection, 4 cases of venous thrombosis of the lower limbs, and 1 case of stroke, respectively. Twenty-six recipients were recovered and discharged after successful weaning from ECMO, six died during ECMO support, six died after weaning from ECMO, five received retransplantation due to unsuccessful weaning from ECMO, and only one survived after retransplantation. Compared with the non-ECMO group, intraoperative cardiopulmonary bypass duration was significantly longer, the proportion of recipients requiring postoperative intra-aortic balloon pump (IABP), dialysis due to renal insufficiency, reoperation for hemostasis, infection, mechanical ventilation time≥96 h and tracheotomy was significantly higher, and the length of postoperative intensive care unit (ICU) stay was significantly longer in the ECMO group (all P < 0.05). The survival rate after discharge and 90-d survival rate in the ECMO group were 63% and 96%, significantly lower than 97% and 100% in the non-ECMO group (both P < 0.05). Survival analysis showed that the long-term survival rate in the ECMO group was significantly lower than that in the non-ECMO group (P < 0.05). After excluding the recipients who died within 90 d after heart transplantation, no significant difference was observed in the long-term survival rate (P > 0.05). Conclusions ECMO is an effective treatment of EAD after heart transplantation. The short-term survival rate of recipients using ECMO after heart transplantation is lower than that of those who do not use ECMO, and there is no significant difference in long-term survival of recipients surviving 90 d after heart transplantation.

ABSTRACT

PURPOSE@#The long-term situation of children with spinal cord injury (SCI) was investigated, and suggestions for helping them better return to the society were provided.@*METHODS@#SCI patients less than 18 years old hospitalized in Beijing Boai Hospital from January 2011 to December 2020 were retrospectively analyzed. Information including motor function, complications, characteristic changes, self-care abilities, school attendance and social participation were collected by telephone interview and electronic questionnaire. All the answers were statistically analyzed.@*RESULTS@#A total of 86 cases were enrolled, 77 girls and 9 boys, with a median injury age of 6 years and 2 months. The follow-up time was 3-130 months. The main cause of trauma in these children was sport injury (66.3%), the thoracic spinal cord was involved the most (91.9%), and complete SCIs accounted for the majority (76.7%). In terms of complications, children with complete SCIs were more likely to have urinary incontinence, constipation and characteristic changes (p < 0.05); whereas the incomplete SCIs often have spasticity (p < 0.05). As to the daily living abilities, children with incomplete lumbar SCIs were more capable to accomplish personal hygiene, transfer, and bathing independently than those with complete injuries, or cervical/thoracic SCIs, respectively (p < 0.05). Moreover, children older than 9 years care more able to dress and transfer independently than the youngers (p < 0.05). Wheelchair users accounted for 84.9% and more than half of them were able to propel wheelchair independently, and those who move passively in wheelchairs were mostly introverted kids (p < 0.05). Almost all (93.8%) children with incomplete injuries were able to walk independently. Most (79.1%) children continued to attending school, and 41.9% participated in interest classes. Unfortunately, 67.4% of the children spent less time playing with their peers than before the injury.@*CONCLUSION@#SCIs impair physical structures and function of children, affect their independence in daily living, and restrict school attendance and social interaction. Comprehensive rehabilitation after injury is a systematic work. Medical staff and caregivers should not only pay attention to neurological function, but also help them improve self-care abilities. It is also important to balance rehabilitation training and school work and social participation.

ABSTRACT

The spine is the most common site of bone metastases from malignant tumors, with metastatic epidural spinal cord compression occurring in about 10% of patients with spinal metastases. Palliative radiotherapy and simple laminectomy and decompression have been the main treatments for metastatic spinal cord compression. The former is ineffective and delayed for radiation-insensitive tumors, and the latter often impairs spinal stability. With the continuous improvement of surgical techniques and instrumentation in recent years, the treatment model of spinal metastases has changed a lot. Decompression surgery underwent open decompression, separation surgery, minimally invasive surgery and laser interintermal thermal ablation decompression. However, no matter what kind of surgical plan is adopted, it should be assessed precisely according to the specific situation of the patient to minimize the risk of surgery as far as possible to ensure the smooth follow-up radiotherapy. This paper reviews the research progress of decompression for spinal metastases.

ABSTRACT

Self-organized blastoids from extended pluripotent stem (EPS) cells possess enormous potential for investigating postimplantation embryo development and related diseases. However, the limited ability of postimplantation development of EPS-blastoids hinders its further application. In this study, single-cell transcriptomic analysis indicated that the "trophectoderm (TE)-like structure" of EPS-blastoids was primarily composed of primitive endoderm (PrE)-related cells instead of TE-related cells. We further identified PrE-like cells in EPS cell culture that contribute to the blastoid formation with TE-like structure. Inhibition of PrE cell differentiation by inhibiting MEK signaling or knockout of Gata6 in EPS cells markedly suppressed EPS-blastoid formation. Furthermore, we demonstrated that blastocyst-like structures reconstituted by combining the EPS-derived bilineage embryo-like structure (BLES) with either tetraploid embryos or tetraploid TE cells could implant normally and develop into live fetuses. In summary, our study reveals that TE improvement is critical for constructing a functional embryo using stem cells in vitro.

ABSTRACT

Objective:To explore the morbidity and risk factors of de novo malignancy after heart transplantation (HT).Methods:From June 2004 to August 2021, 995 patients undergoing HT were selected and followed up.The epidemiological characteristics, the morbidity of de novo malignancy (DNM) and its risk factors were examined.Kaplan-Meier survival analysis was performed for calculating the cumulative incidence and mortality of DNM.Log rank test was utilized for comparing the survival rate of each subgroup.Cox regression model was employed for examining the relationship between the included factors and the endpoint of DNM.Results:The median follow-up period was 6.36(3.64, 10.18) years.Thirty-six patients (3.6%) developed DNM during follow-up.Lung cancer accounted for 22.2%(8/36) of DNM while digestive system tumors accounted for 38.9% (including gastric cancer 6/36, 16.7%; liver cancer 3/36, 8.3%; colon cancer 2/36, 5.6%). The cumulative morbidity of DNM at Year 1/5/10/15 post-HT was 0.1%, 2.3%, 4.9% and 7.6% respectively.The median survival time of DNM recipients was 83.32 months.The mean survival time was significantly lower than those without DNM[(115.32±13.12) vs.(194.22±2.58), P<0.001]. The mortality of DNM recipients was around 6.57 folds higher ( HR=6.57, 95% CI: 4.06-10.64, P<0.01). Age was an independent risk factor for an occurrence of DNM.Hypertension and diabetes were also correlated with DNM. Conclusions:DNM after HT is associated with shorter survival time.And age is an independent risk factor for DNM after HT.

ABSTRACT

Objective:To summarize the incidence and long-term outcomes of postoperative renal dysfunction(RD) and explore the clinical predictors of postoperative RD to provide reference for preoperative evaluation and perioperative management of heart transplantation(HT).Methods:The relevant clinical data are retrospectively reviewed for 1 095 HT recipients.They are grouped into two groups of RD(352 cases)and non-RD(normal, 743 cases)according to whether or not RD occurred after HT.Two groups are compared to explore the clinical predictors associated with postoperative RD.For further examining the prognostic impact of perioperative renal dysfunction, the recipients are assigned into four groups based upon perioperative renal function.The long-term outcomes of four groups are compared.Results:The median follow-up period is 5.6 years.Among 352 RD patients (32.1%), there are new-onset(276 cases, 25.2%), occurring during postoperative hospitalization (99, 28.1%)and post-discharge until Year 1(111 cases, 31.5%).Compared with normal group, RD group have advanced age, greater body mass index(BMI), higher preoperative serum creatinine, longer cardiopulmonary bypass time, a higher ratio of male, diabetic history, preoperative RD, transplantation for previous graft failure, preoperative extracorporeal membrane oxygenerator(ECMO)and intra-aortic balloon pump(IABP); donors in this group had advanced age and higher ratio of male (all P<0.05).In terms of postoperative data, RD group had higher ratios of ECMO/IABP implantation, tracheostomy, infection, longer postoperative mechanical ventilation time, intensive care unit(ICU)stay and in-hospital stay than normal group( P<0.05).Long-term survival of patients with postoperative RD is significantly lower than that with postoperative normal kidney function( P<0.01).Long-term survival rate of patients with preoperative RD is significantly lower than that of those without preoperative RD, regardless of whether or not kidney function normalized postoperatively; long-term survival rate of patients with postoperative new-onset RD is significantly lower than that in those with normal kidney function( P<0.01).Advanced recipient age, higher BMI, existence of preoperative RD, postoperative cyclosporine dosing(versus tacrolimus)and cold ischemic time≥6 h are independent risk factors of RD post-HT. Conclusions:RD occurs predominantly within the first year post-HT.Advanced recipient age, higher BMI, existence of preoperative RD and cold ischemic time≥6 h are independent predictors of RD post-HT.The incidence of RD post-HT significantly affects perioperative and long-term survivals.

ABSTRACT

OBJECTIVE@#To observe the effect of buccal acupuncture on pain after lumbar spinal fusion.@*METHODS@#Sixty patients undergoing lumbar spinal fusion were randomly divided into an observation group (30 cases, 1 case dropped off) and a control group (30 cases, 1 case was eliminated). The patients in the control group were treated with routine anesthesia. On the basis of the control group, the patients in the observation group were treated with buccal acupuncture at bilateral back point, waist point, and sacral point for 30 min per treatment. The first acupuncture was given before anesthesia induction, and then once a day postoperation for two days, totally 3 treatments. The dosage of sufentanil, the number of remedial analgesia, and the incidence of nausea and vomiting within 48 h after surgery were compared between the two groups; rest and motion visual analogue scale (VAS) scores at 2 (T1), 8 (T2), 12 (T3), 24 (T4), and 48 (T5) h after surgery were observed; the quality of recovery-15 scale (QoR-15) at 24 and 48 h after surgery were evaluated.@*RESULTS@#The dosage of sufentanil and the number of remedial analgesia within 48 h after surgery in the observation group were lower than those in the control group (P<0.01). There was no significant statistically difference in rest and motion VAS scores between the two groups in T1, T2, T3, T4 and T5 (P>0.05). The QoR-15 scores in the observation group at 24 and 48 h after surgery were higher than those in the control group (P<0.01). The incidence of nausea in the observation group was lower than that in the control group (P<0.05).@*CONCLUSION@#Buccal acupuncture could reduce the amount of postoperative analgesic drugs of patients after lumbar spinal fusion, and promote early postoperative recovery.

ABSTRACT

Objective To evaluate the effect of renal insufficiency before heart transplantation on perioperative death, complications and long-term survival, and to compare the differences between preoperative serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) in preoperative risk assessment. Methods Clinical data of 1 095 heart transplant recipients were retrospectively analyzed. According to preoperative Scr level, all recipients were divided into the Scr < 133 μmol/L(n=980), Scr 133-176 μmol/L (n=83) and Scr≥177 μmol/L groups (n=32). According to preoperative eGFR, all recipients were divided into eGFR≥90 mL/(min·1.73m2) (n=436), eGFR 60-89 mL/(min·1.73m2) (n=418) and eGFR < 60 mL/(min·1.73m2) groups (n=241). Clinical prognosis of postoperative renal function, perioperative and long-term outcomes of recipients were compared among different groups. The effect of eGFR and Scr level on renal function injury and long-term survival after heart transplantation was assessed. Results With the increase of preoperative Scr level, the proportion of recipients undergoing postoperative continuous renal replacement therapy (CRRT) was increased, the proportion of recipients receiving postoperative mechanical circulatory support was elevated, the incidence of postoperative complications was increased, the duration of mechanical ventilation and intensive care unit(ICU) stay was prolonged, and the in-hospital fatality was increased. The differences among three groups were statistically significant (all P < 0.05). With the decrease of preoperative eGFR, the proportion of recipients receiving postoperative CRRT was increased, the proportion of recipients using postoperative intra-aortic balloon pump (IABP) was elevated, the duration of mechanical ventilation and ICU stay was prolonged, and the in-hospital fatality was increased. The differences among three groups were statistically significant (all P < 0.05). Scr≥177 μmol/L was an independent risk factor for postoperative death [adjusted hazard ratio (HR) 3.64, 95% confidence interval (CI) 1.89-6.99, P < 0.01]. Among different groups classified by Scr and eGFR, the cumulative incidence rate of postoperative renal function injury and long-term survival rate were statistically significant among three groups (all P < 0.05). In patients with preoperative Scr < 133 μmol/L, the cumulative incidence rate of postoperative long-term renal function injury was significantly increased with the decrease of preoperative eGFR (P < 0.01). There was no significant difference in postoperative long-term survival rate among patients stratified by different eGFR (P > 0.05). Conclusions Renal insufficiency before heart transplantation is associated with poor perioperative and long-term prognosis. Preoperative Scr and eGFR are the independent risk factors for postoperative renal function injury. Scr yields low sensitivity in the assessment of preoperative renal function, whereas it has high accuracy in predicting perioperative death risk. And eGFR is a more sensitive parameter to evaluate preoperative renal function, which may identify early-stage renal functional abnormality and take effective measures during early stage to reduce adverse effect on prognosis.

ABSTRACT

Neuropathic pain is a chronic disease that severely afflicts the life and emotional status of patients, but currently available treatments are often ineffective. Novel therapeutic targets for the alleviation of neuropathic pain are urgently needed. Rhodojaponin VI, a grayanotoxin from Rhododendron molle, showed remarkable antinociceptive efficacy in models of neuropathic pain, but its biotargets and mechanisms are unknown. Given the reversible action of rhodojaponin VI and the narrow range over which its structure can be modified, we perforwmed thermal proteome profiling of the rat dorsal root ganglion to determine the protein target of rhodojaponin VI. N-Ethylmaleimide-sensitive fusion (NSF) was confirmed as the key target of rhodojaponin VI through biological and biophysical experiments. Functional validation showed for the first time that NSF facilitated trafficking of the Cav2.2 channel to induce an increase in Ca2+ current intensity, whereas rhodojaponin VI reversed the effects of NSF. In conclusion, rhodojaponin VI represents a unique class of analgesic natural products targeting Cav2.2 channels via NSF.

ABSTRACT

Objective To better carries out the review of the interaction between triazole antifungal drugs and statins, ensure drug safety for patients and improve the efficiency of the manual review of pharmacists. Methods The advantageous combination with less interaction between the two kinds of drug was obtained by summarizing the interaction information of triazole antifungal drugs and statins. At the same time, optimizing the process of full manual reviews for drug interaction, and the advantageous combination of the two kinds of drug will be set up in advance on the doctor side of the review system. Doctors can adjust the drug in time according to the prompts of the information system when there is a significant interaction of the two kinds of drug in the prescription or medical order, which is issued by the doctors. Results After optimization, most doctors choose the drug combination of less interaction between the two kinds of drug according to the system prompts. The number of drug combinations of significant interaction which is manually reviewed by pharmacists is significantly reduced (P<0.05), and the review efficiency is improved, the drug safety risks brought by drug interactions to patients are reduced. Conclusion Refinement review of drug interactions between triazole antifungal agents and statins based on the optimization of the pre-audit system plays a positive role in improving the safety of patients’ medication and the efficiency of pharmacists' manual auditing.

ABSTRACT

Objective To summarize the incidence of cardiac allograft vasculopathy (CAV) after heart transplantation and the effect on the long-term survival of recipients. Methods Clinical data of 1 006 heart transplant recipients were retrospectively analyzed. Of 48 CAV patients, 4 cases were not included in this analysis due to lack of imaging evidence. A total of 1 002 recipients were divided into the CAV group (n=44) and non-CAV group (n=958) according to the incidence of CAV. The incidence of CAV was summarized. Clinical data of all patients were statistically compared between two groups. Imaging diagnosis, coronary artery disease, drug treatment and complications, postoperative survival and causes of death of CAV patients were analyzed. Results Among 1 006 heart transplant recipients, 48 cases (4.77%) developed CAV. Compared with the non-CAV group, the proportion of preoperative smoking history, preoperative hypertension history, coronary artery disease and perioperative infection was significantly higher in the CAV group (all P < 0.05). Among 44 patients diagnosed with CAV by imaging examination, 24 cases were diagnosed with CAV by coronary CT angiography (CTA), 4 cases by coronary angiography (CAG), and 16 cases by coronary CTA combined with CAG. Among 44 patients, the proportion of grade Ⅰ CAV was 45% (20/44), 30% (13/44) for grade Ⅱ CAV and 25% (11/44) for grade Ⅲ CAV, respectively. All patients received long-term use of statins after operation, and 20 patients were given with antiplatelet drugs. Among 44 CAV patients, 11 patients underwent percutaneous coronary intervention, 6 cases received repeated heart transplantation, and 8 patients died. Kaplan-Meier survival analysis demonstrated that there was no significant difference in the long-term survival rate between the CAV and non-CAV groups (P > 0.05), whereas the survival rate of patients tended to decline after the diagnosis of CAV (at postoperative 6-7 years). The long-term survival rates of patients with grade Ⅰ, grade Ⅱ and grade Ⅲ CAV showed no significant difference (P > 0.05). Even for patients with grade Ⅰ CAV, the long-term survival rate tended to decline. Conclusions CAV is a common and intractable complication following heart transplantation, and the long-term survival rate of patients after the diagnosis of CAV tended to decline. Deepening understanding of CAV, prompt prevention, diagnosis and treatment should be delivered to improve the long-term survival rate of patients after heart transplantation.

ABSTRACT

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

ABSTRACT

Acephalic spermatozoa syndrome is a rare type of teratozoospermia that severely impairs the reproductive ability of male patients, and genetic defects have been recognized as the main cause of acephalic spermatozoa syndrome. Spermatogenesis and centriole-associated 1 like (SPATC1L) is indispensable for maintaining the integrity of sperm head-to-tail connections in mice, but its roles in human sperm and early embryonic development remain largely unknown. Herein, we conducted whole-exome sequencing (WES) of 22 infertile men with acephalic spermatozoa syndrome. An in silico analysis of the candidate variants was conducted, and WES data analysis was performed using another cohort consisting of 34 patients with acephalic spermatozoa syndrome and 25 control subjects with proven fertility. We identified biallelic mutations in SPATC1L (c.910C>T:p.Arg304Cys and c.994G>T:p.Glu332X) from a patient whose sperm displayed complete acephalia. Both SPATC1L variants are rare and deleterious. SPATC1L is mainly expressed at the head-tail junction of elongating spermatids. Plasmids containing pathogenic variants decreased the level of SPATC1L in vitro. Moreover, none of the patient's four attempts at intracytoplasmic sperm injection (ICSI) resulted in a transplantable embryo, which suggests that SPATC1L defects might affect early embryonic development. In conclusion, this study provides the first identification of SPATC1L as a novel gene for human acephalic spermatozoa syndrome. Furthermore, WES might be applied for patients with acephalic spermatozoa syndrome who exhibit reiterative ICSI failures.

ABSTRACT

Objective: To evaluate the safety and feasibility of laparoscopic surgery after neoadjuvant chemotherapy for pancreatic cancer. Methods: Clinical data of 8 patients underwent laparoscopic surgery after neoadjuvant chemotherapy for pancreatic cancer at Fudan University Shanghai Cancer Center from September 2019 to June 2020 were reviewed retrospectively. There were 5 males and 3 females,aged from 47 to 72 years old. All patients underwent abdominal enhanced CT and PET-CT before operation to accurately evaluate the tumor stage and exclude distant metastasis. Results: Neoadjuvant chemotherapy with AG regimen(gemcitabine 1 000 mg/m2 and albumin bound paclitaxel 125 mg/m2) was received for 2 to 6 cycles before surgery. All 8 patients successfully completed the operation,including 5 cases of pancreaticoduodenectomy,2 cases of radical antegrade modular pancreatosplenectomy(RAMPS),and 1 case of total pancreatectomy. No conversion to laparotomy or laparoscopic assisted surgery. The operation time was 240 to 450 minutes,the blood loss was 100 to 500 ml,the postoperative length of stay was 10 to 16 days. During the follow-up period up to December 31, 2020, there was 1 case suffered grade B pancreatic leakage and abdominal infection. The numbers of resected lymph nodes were 9 to 31. All patients received R0 resection. The follow-up times were 4.5 to 9.5 months. One patient underwent RAMPS was diagnosed as liver metastasis after 2 months of the operation,and the other 7 patients still survived without tumor recurrence. Conclusion: Minimally invasive surgery of pancreatic cancer after neoadjuvant chemotherapy is safe and feasible in experienced pancreatic minimally invasive centers.

ABSTRACT

Objective:to analyze the risk factors for the side effect of anti-reflux surgery for gastroesophageal reflux disease (GERD) with regards to relief of reflux symptom, dysphagia and postoperative satisfaction.Method:The incidence of disappointing chief complaint among 192 patients who underwent anti-reflux surgery was analyzed. The related independent risk factors were identified by multivariate analysis.Results:The incidence of non-relief of reflux symptom was approximately 21.8% (42 cases), of which the risk factors were identified as preoperative depression and long-term PPI administration. The incidence of persistent dysphagia was 7.3% (14 cases), of which the risk factors were identified as preoperative depression and weak peristalsis of esophageal body. The incidence of postoperative dissatisfaction was 26.0% (50 cases), of which the risk factors were identified as long-term PPI administration and moderate-severe depression. The GERD patients with hiatal hernia and low pressure of lower esophageal sphincter were more likely benefit from anti-reflux surgery and had a higher postoperative satisfaction rate.Conclusion:Hiatal hernia and low pressure of lower esophageal sphincter are the favorable factors predicting good result of anti-reflux surgery. Long-term PPI administration and preoperative depression is an indication for poor result of anti-reflux surgery.

ABSTRACT

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.
