ABSTRACT
Objective:To investigate the correlation of lung ultrasound score and poor prognosis in internal shock patients in intensive care unit (ICU).Methods:The clinical data of 200 shock patients admitted to the ICU of Wuzhou Red Cross Hospital from July 2019 to June 2021 were selected for study. According to the prognosis of patients, they were divided into survival group and death group. The clinical data of shock patients in ICU with different prognosis were analyzed by single factor analysis, multiple factor regression analysis and predictive value analysis.Results:All patients were followed up. The end point of the study was death or transfer from ICU. The follow-up period was 28 days, with a median of 16 days. The 28-day survival rate (OS) of all patients was 62.5%(125/200). The Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, prothrombin time (PT), Fbg, D-dimer(D-D), lactic acid, oxygenation index and lung ultrasound score of the patients in the survival group and the death group were significantly different (all P<0.05), while other indexes were not significantly different (all P>0.05). The results of COX multivariate analysis showed that APACHE Ⅱ score, lactate, and lung ultrasound score were independent prognostic factors of shock patients in ICU (all P<0.05). The survival curves of patients with different lung ultrasound scores were significantly different ( P<0.05). The higher the lung ultrasound score, the lower the 28-day survival rate ( P<0.05). The receiver operating characteristic(ROC) curve analysis showed that the area under curve (AUC), sensitivity and specificity of predicting the prognosis of patients with lung ultrasound score were 0.753, 76.0% and 71.2%, respectively; The AUC , sensitivity and specificity of APACHE Ⅱ score were 0.774, 77.3% and 79.2% respectively; The AUC, sensitivity and specificity of lactic acid were 0.783, 81.3% and 68.8% respectively, with no significant difference (all P>0.05). Conclusions:The lung ultrasound score , lactic acid and APACHE Ⅱ scores are independent risk factors affecting the prognosis of ICU shock patients, and have considerable predictive value.
ABSTRACT
Bladder cancer (BCa) is one of the most common cancers in urology,whose pathogenesis is still unclear. Methyltransferase-like 3(METTL3) is the most important part of N6-methyladenosine methyltransferase complex (m6A MTC),which mediates the methylation of mRNA to regulate the stability and translation process of mRNA. Researches have shown that METTL3 can promote BCa development via AFF4/NF-κB/MYC signaling network,which involves many kinds of signaling molecules. In addition,METTL3 can affect the expressions of AFF4,NF-κB and MYC,so as to affect their downstream signaling pathways and finally promote the malignant progression of tumor.
ABSTRACT
The number of benign prostatic obstruction (BPO) patients in China is increasing, and patients tend to be younger and younger. The former "gold standard" scheme of transurethral resection of the prostate (TURP) is more suitable for patients with prostate volume ranging from 40 mL to 80 mL, which may lead to excessive resection in patients with small prostate volume and low efficiency in patients with large prostate volume. New minimally invasive techniques have been introduced,including prostate artery embolization, laser surgery (such as holmium, green, diode, and thulium), minimally invasive simple prostatectomy, transperineal laser ablation, prostatic urethral lift,and robot-assisted water jet ablation of the prostate. These methods are alternatives to TURP and increasingly used in the treatment of BPO. This article reviewed the advances in minimally invasive treatment of BPO.
ABSTRACT
In the COVID-19 outbreak, several general hospitals in Wuhan were transferred to designated hospitals. However, most of the designated hospitals had suffered from insufficient oxygen supply in different degrees. Taking a designated hospital as an example, this paper summarized the emergency management system of oxygen supply from the aspects of engineering transformation, process formulation and safety management through the PDCA cycle theory, discussed the management experience of oxygen supply under the epidemic situation, and explored the management mode of emergency normalization from the perspective of peacetime and wartime integration. The purpose was to provide reference for the management of medical oxygen supply in public health emergencies and normal operation.
ABSTRACT
Objective:To explore the efficacy and safety of transvaginal anterior pelvic floor reconstruction with mesh in treatment of patients with cystocele and lower urinary tract symptoms.Methods:A retrospective analysis of 32 patients who underwent transvaginal anterior pelvic reconstruction with mesh from June 2015 to February 2019 was performed. The age of the patients was 57-86 years old, with an average of (67.8±7.6) years; body mass index(BMI) (22.6±3.0) kg/m 2; mean duration of disease (2.9±2.3) years; delivery 1-7 times, mean(3.0±1.5) times. All patients underwent transvaginal anterior pelvic reconstruction. The anterior wall of the vagina was incised, and the space between the pelvic floor and the bladder was bluntly separated. The mesh was placed under the guidance of the puncture needle after locating marks of body surface. Patients underwent the American Urological Association Symptom Scoring (AUASS) with (14.2±3.5) points, the residual urine (71.3±53.0) ml and the maximum urine flow rate (16.9 ± 3.8) ml/s were measured preoperative. The Pelvic Organ Prolapse Distress Inventory(POPDI-6), Urogenital Distress Inventory(UDI-6) and Pelvic Floor Impact Questionnaire(PFIQ-7) were recorded as the value of (48.0±7.3) points, (41.7 ± 8.2) points and (62.5 ± 16.4) points, respectively. Thirty-two patients were divided into 2 groups as the group of urinary storage symptom (22 patients) and the group of voiding symptom (10 patients) according to the preoperative lower urinary tract symptoms. The operative time, intraoperative bleeding volume and average hospital stay were recorded. The patients were followed up with AUASS, maximum urine flow rate, residual urine, POPDI-6, UDI-6, PFIQ-7 and complications during and after operations. Results:All the operations of 32 cases were successfull. The average operation time was (61.1±18.6) min, the average intraoperative blood loss was (41.5±12.3)ml, and the average hospital day was (9.1±1.8)d. There were no major organ injuries such as bladder, ureter, iliac vessels and rectum. 27 patients were followed up for 3 to 36 months, with an average of (24.7±10.8) months. There significant improvement of LUTS. At the last follow-up, the AUASS storage phase score (3.4±1.9) points in the urinary storage symptom group(19 patients) and the AUASS urinating phase score (3.9±1.7) points in the voiding symptom group(8 patients) were compared with the preoperative AUASS scores (11.6±1.9) points and (13.9±1.2) points which were significantly reduced. By the last follow up of all the 27 patients, residual urine (23.4±11.0)ml, POPDI-6(3.1±5.4) points, UDI-6 (3.2±5.1) points and PFIQ-7 (12.4±1.7) points were significantly lower than preoperative data. The maximum urinary flow rate(22.4±4.1)ml/s, was significantly higher than that before the operation. All the differences were statistically significant ( P<0.05). All patients had no recurrence of cystocele. One patient had anterior vaginal wall mesh exposure 3 months after surgery. After removing excess mesh in the outpatient clinic, she was cured by smearing with estrogen ointment. One patient experienced frequent urination and urgency who was cured by oral tolterodine tartrate. One patient with de novo mild SUI during the 1-year follow-up. The symptoms were improved in the outpatient clinic after pelvic floor muscle exercise. At 2-year follow-up, one patient was observed de novo mild posterior wall prolapse with no clinical manifestations and no treatment was carried out. Conclusions:Transvaginal anterior pelvic reconstruction with mesh could be effective in treating cystocele with lower urinary tract symptoms with less surgical trauma, fewer complications and lower recurrence rate. It could effectively improve lower urinary tract symptoms such as frequent urination, urgency and difficulty urinating.However, safety issues such as the incidence of long-term de novo SUI and mesh exposure still require further long-term follow-up.
ABSTRACT
Objective To understand the infected strains and prevalence of brucellosis in occupational population in Tacheng and Kashgar regions,Xinjiang Uygur Autonomous Region.Methods In September 2015,blood samples from occupational population (including herders,semi-agricultural and semi-pastoral,veterinarians) and non-occupational population (including students and cadres) were collected to detect Brucellaspecific antibody and bacterial nucleic acids by rose bengal plate test (RBPT),serological standard tube agglutination test (SAT) and PCR methods,respectively.The positive products of PCR were sent to Shanghai Sangon Biotechnology Co.,LTD.Then the sequence results were retrieved online using the basic alignment search tool (BLAST) in GenBank web page and uploaded to NCBI (National Center for Biotechnology Information).Results A total of 546 blood samples were tested,including 300 males,aged (55-± 15) years old,and 246 females,aged (54 ± 12) years old.The positive rates were 17.58％ (96/546) and 6.78％ (37/546) in 546 blood samples by serological method and genetic markers targeting omp22 and omp2,respectively.The positive rates were statistically significant (x2 =29.8,P ＜ 0.05).Additionally,based on BLAST analysis of outer membrane protein omp22 and omp2 genes,the positive products were identified as Brucella abortus,and the sequence similarity was 100.00％ (253/253,863/863 bp) to Brucella abortus strain Wisconsin genome assembly,chromosome (LT651712).Conclusions Brucellosis has a high infection rate in the occupational population of some animal husbandry-based groups in Xinjiang.The infection strain is abortive species Brucella,and health education for the occupational population and prevention of brucellosis should be strengthened to reduce the infection rate.
ABSTRACT
OBJECTIVE@#To evaluate the efficiency of autologous conchal cartlage in ossicular chain reconstruction in patients with chronic suppurative otitis media.@*METHOD@#Seventy-three cases of chronic suppurative otitis media (COM) with or without cholesteatoma who had undergone mastoidectomy with tympanoplasty and ossicular chain reconstruction(OCR) using autologous conchal cartilage as prosthesis were studied retrospectively. Sixty-six cases of COM who had undergone mastoidectomy with tympanoplasty and without OCR were studied as control. The examination of pure tone hearing level of air conduction(AC) and bone conduction(BC) was done before operation, 2 months and 6 months after operation respectively. The pure tone average (PTA) of 0.5, 1.0, 2.0 kHz was observed.@*RESULT@#The average air conduction gain was more than 15dB or the PTA (AC) was less than 25 dB 2 months after operation in 35 out of 73 cases who had undergone OCR. Nevertheless, the data became 56 out of 73 cases 6 months after operation. In the control group, The average air conduction gain was more than 15dB or the PTA(AC) was less than 25 dB 2 months after operation in 10 out of 66 cases who had not undergone OCR. The data became 14 out of 66 cases 6 months after operation. In OCR group, air bone gap(ABG) was less than 20 dB in 39 cases 2 months after operation and in 57 cases 6 months after operation. In the control group without OCR, ABG was less than 20 dB only in 11 cases 2 months after operation and in 16 cases 6 months after operation. By statistically analysis, there was significant difference of postoperative hearing improvement between the two groups.@*CONCLUSION@#The autologous conchal cartilage can be used as the material of prosthesis for ossicular chain reconstruction in the operation of chronic otitis media. It has many advantages, such as easily--obtained, good histocompatibility, easy to shape and so on.

Objective To study the dynamic changes of plasma C-reactive protein (CRP) and cortisol (COR) and their clinical value in prognosis of patients with sepsis. Methods Daily CRP and COR detection was conducted to record the dynamic changes of CRP and COR for cases of sepsis patients in ICU then the rela-tionship between dynamic changes of serum CRP and COR and prognosis were analyzed. Results Serum CRP and COR levels of dead patients were significantly higher than those of survival patients after treatment (P <0.05). According to the difference of the dynamic changes of CRP and COR, the data were divided into typeⅠ:sustained elevated type , typeⅡ: up-and-down type , type Ⅲ: fluctuated type and type Ⅳ: normal or mild ele-vation type. The mortality of CRP typeⅠ patients was significantly higher than that of type Ⅱ and type Ⅳ(P <0.001). The mortality of COR typeⅠ and COR Ⅲ patients was significantly higher than that in COR Ⅱand COR Ⅳ (P < 0.001). Further analysis showed that the mortality of group with significant elevation of CRP and COR were obviously higher than that of group with significant increase of CRP or COR and that of group with no significant elevation of CRP and COR (P < 0.001); the mortality of group with significant increase of CRP or COR was also significantly higher than that of group with no significant elevation of CRP and COR (P < 0.001). Conclusions The dynamic changes of COR and CRP in patients with sepsis present certain regularity and monitor-ing the dynamic changes of the two provides accurate assessment of the prognosis of sepsis.
ABSTRACT
Objective To prepare a conjugate vaccine by linking Haemophilus influenzae type b (Hib)polysaccharide to PsaA protein carrier and evaluate the immunogenicity and efficacy of the conjugate vaccine. Methods A recombinant protein rPsaA,expressed by using the genetic engineering technology, was used as a protein carrier to prepare conjugate vaccine together with Hib polysaccharide. Ten mice at age of 3 weeks were immunized with the conjugate vaccine,while another 10 age-matched mice were immunized with Hib-tetanus toxoid(Hib-TT)vaccine which was produced formerly as a control. The mice treated with equal volume of PBS were set up as the negative control. The IgG antibodies in serum samples against PsaA and Hib polysaccharide were detected in two weeks after the final immunization. A suspension of Pneumococ-cus was injected into the middle ears of mice from experiment and control group. Histopathological analysis was performed to measure the clearance of bacteria in the middle ears and the severity of infection on days 3 and 7 after bacterial challenge. Results The rPsaA protein was prepared by the genetic engineering tech-nology and purified successfully with anion-exchange column. The Hib polysaccharide-PsaA protein conju-gate vaccine was prepared through a series of amide condensation reactions. The detection of IgG antibodies against PsaA protein and Hib polysaccharide in the immunized mice demonstrated that there was no signifi-cant difference with the titer of IgG against Hib polysaccharide between the mice immunized with the Hib-PsaA conjugate vaccine and those immunized with the Hib-TT vaccine. Less Pneumococcus strains were de-tected in the middle ears of mice immunized with the conjugate vaccine than those mice immunized with the Hib-TT vaccine three days after challenge. The mice from control group showed severe inflammation in the middle ears than those from experiment group. The Hib polysaccharide-PsaA protein conjugate vaccine im-proved protection against Pneumococcus infections as compared with the Hib-TT vaccine. Conclusion The rPsaA protein could be produced by genetic engineering technology and purified by anion-exchange column. The Hib polysaccharide was successfully conjugated with the rPsaA protein through amide condensation reac-tion. Both anti-PsaA and anti-Hib immune responses were induced in young mice by the injection of Hib pol-ysaccharide-PsaA protein conjugate vaccine. Apart from providing protection against Hib infection,the con-jugate vaccine might also be used for the prevention of acute otitis media caused by Pneumococcus infection.
ABSTRACT
OBJECTIVE@#To study the incidence of high jugular bulb (HJB) in the patients with chronic otitis media and to explore the management of its active bleeding during middle ear surgery.@*METHOD@#From January 2005 to August 2006, consecutive 287 patients undergoing surgical intervention for chronic otitis media were retrospectively studied. The high resolution CT (HRCT) scan and the surgical technique for diagnosis and management of bleeding of jugular bulb were also discussed.@*RESULT@#Sixty-five patients (22.6%) were diagnosed as HJB by HRCT scan, including 21 men and 44 women (P<0.01), with their ages ranged from 7 to 68 years (mean 41 years). Fourteen cases of them were on the left side, and 31 were on the right side (P<0.05). Twenty cases showed bilateral HJB. Five cases were found dehiscent high jugular bulb by CT scan and were confirmed in operation. Active bleeding was encountered in one case while elevating the pathological eardrum in hypotympanum. It was treated by pressure compression using collagen gelfoam cushion covered by muscle to protect the dehiscent bulb. The patients proceed through the planned surgery without complications.@*CONCLUSION@#HJB might cause hemorrhage during middle ear surgery, but preliminary attention, correct treatment and awareness of the pitfalls may lessen the operation risk.
