[Objective] To summarize the clinical manifestations, pathological characteristics, treatment options and prognosis of the world's first case of prostate ductal adenocarcinoma (PDA) complicated with prostate mucinous adenocarcinoma (PMA). [Methods] The clinical and follow-up data of a patient with PDA and PMA treated in Zhongnan Hospital of Wuhan University were retrospectively analyzed, and relevant literature in PubMed and CNKI databases was retrieved. [Results] The patient sought medical attention due to dysuria, frequent urination, urinary urgency and urinary pain for more than half a year, and was admitted to hospital 3 times in total.The initial diagnosis upon the first admission was benign prostatic hyperplasia complicated with prostatic abscess.After 2 months, the patient was readmitted due to worsening symptoms, received transurethral bladder neck incision+ cystoscopy+ transurethral plasma resection of the prostate, and postoperative diagnosis confirmed PDA with local PMA.Three months after surgery, the patient had bleeding.After auxiliary examinations revealed extensive metastasis, he received hormonal therapy.After 9 months, the patient died due to multiple lung metastases. [Conclusion] Early diagnosis has a significant impact on the treatment and prognosis, but there have been no previous reports of PDA combined with PMA, so the lack of specific biomarkers in the early stage has led to missed diagnosis or misdiagnoses.There is no specific treatment for PDA with PMA. Radical prostatectomy was not satisfactory in the treatment of this case.

Objective:To compare the real-world efficacy and safety profile of tenofovir amibufenamid (TMF) and tenofovir alafenamide (TAF) tablets in the treatment of patients with chronic hepatitis B (CHB).Methods:This retrospective study included patients with chronic hepatitis B who received TMF and TAF antiviral treatment at the Infectious Disease Outpatient Department of the First Affiliated Hospital of Zhengzhou University from January 2021 to December 2023. The primary and secondary outcome was to study the patient HBV DNA conversion rate (<20 IU/ml), alanine aminotransferase (ALT) normalization rate, renal function, and lipid levels of patients at 48 weeks of treatment. The comparison of data between measurement data groups was differentiated using a t-test and Mann-Whitney U test. The inter-group comparison rate in count data was performed using the χ2 test or Fisher's exact probability. Results:A total of 440 cases were enrolled, including 220 in the TMF group (63 treatment-na?ve and 157 treatment-experienced) and 220 cases in the TAF group (61 treatment-na?ve and 159 treatment-experienced). In terms of efficacy, the HBV DNA seroconversion rates in the TMF group and TAF group were 90.5% and 85.2% ( P=0.372), respectively, while the ALT normalization rates were 92.1% and 88.5% ( P=0.505), respectively, at 48 weeks of treatment. The HBV DNA-negative conversion rate for the newly treated patients was 99.4% and 98.7%, respectively ( P=1.000), while the rates of ALT normalization were 94.9% and 92.3%, respectively ( P=0.863). In terms of safety profile, the serum creatinine level was lower in the TMF group than that in the TAF group at 48 weeks of treatment [TMF group 66.5 (56.3, 78.3) μmol/L, TAF group 70.6 (60.7, 77.8) μmol/L, Z=-2.282, P=0.022]. However, there was no statistically significant difference in other renal function and tubular function related indicators between the two groups of patients ( P>0.05). The serum high-density lipoprotein levels were higher in the TMF group than those in the TAF group [TMF 1.4 (1.1, 1.6) mmol/L vs. TAF group 1.3 (1.1, 1.6) mmol/L, Z=-2.204, P=0.027] at 48 weeks of treatment. However, there was no statistically significant difference in other blood lipid indicators between the two groups of patients ( P>0.05). Conclusion:There is no statistically significant difference in efficacy and safety profiles between TMF and TAF at 48 weeks in the treatment of patients with chronic hepatitis B, and the overall safety profile is favorable.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a child with multiple pterygium syndrome (MPS). METHODS: A child with MPS who was treated at the Orthopedics Department of Guangzhou Women and Children's Medical Center Affiliated to Guangzhou Medical University on August 19, 2020 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and her parents were also collected. Whole exome sequencing (WES) was carried out for the child. Candidate variant was validated by Sanger sequencing of her parents and bioinformatic analysis. RESULTS: The child, an 11-year-old female, had a complain of "scoliosis found 8 years before and aggravated with unequal shoulder height for 1 year". WES results revealed that she has carried a homozygous c.55+1G>C splice variant of the CHRNG gene, for which both of her parents were heterozygous carriers. By bioinformatic analysis, the c.55+1G>C variant has not been recorded by the CNKI, Wanfang data knowledge service platform and HGMG databases. Analysis with Multain online software suggested that the amino acid encoded by this site is highly conserved among various species. As predicted with the CRYP-SKIP online software, the probability of activation and skipping of the potential splice site in exon 1 caused by this variant is 0.30 and 0.70, respectively. The child was diagnosed with MPS. CONCLUSION The CHRNG gene c.55+1G>C variant probably underlay the MPS in this patient.

OBJECTIVE：To investigate the role of clinical pharmacists on the individualized treatment of children with subglottic Talaromyces marneffei infection. METHODS ：The clinical pharmacists participated in the medication procedure for a case of subglottic T. marneffei infection child . The clinical pharmacists suggested that Budesonide suspension for inhalation should be stopped，according to the subglottic infection pathogen type （T. marneffei ）；Itraconazole oral solution should be chosen and taken orally 2.5 mg/kg，q12 h，and indicators as liver function ，blood potassium should be monitored regularly. However ，as Itraconazole oral solution needed to be applied for temporary purchase ，Itraconazole capsules 2.5 mg/kg，q12 h，p.o.，was administrated temporarily ；clinical pharmacists suggested that Itraconazole capsules should be taken after meal ，and the doctor changed the feeding mode of milk from q 4 h to continuous pumping. After purchased ，Itraconazole oral solution was used instead 2.5 mg/kg，q12 h in fasting state ，and according the clinical pharmacist ’s suggestion ，the doctor changed the nursing method to q 4 h milk pumping. After purchasing and using oral solution instead ，clinical pharmacists suggested taking it at fasting state ；according to the monitoring results and target range （0.5-1 mg/L），oral dose of Itraconazole oral solution was finally adjusted to 8.3 mg/kg， q12 h. In view of the diarrhea during the treatment ，clinical pharmacists suggested to continue the original treatment after considering the effectiveness and importance of the treatment ；at the same time ，discharge medication education should be carried out. RESULTS ： The doctors adopted the suggestions of the clinical pharmacists. The child got a clinical improvement and was discharged after 48 days. CONCLUSIONS ：Clinical pharmacists participate in the treatment of children with T. marneffei infection，timely assist physicians to adjust and improve the medication regimen ，which improve the efficacy and safety of medication for children.

Objective:To compare the clinical effect of Ilizarov frame and unilateral frame in the treatment of tibial segmental bone defect combined with soft tissue defect by open bone transport.Methods:A retrospective case-control study was conducted to analyze the clinical data of 32 patients with tibial segmental bone defect and soft tissue defect-up who underwent open bone transport technique in Tianjin Hospital from August 2008 to August 2016 and obtained complete followed-up. There were 22 males and 10 females, aged 22-64 years (mean, 36.8 years). Nineteen patients in the Ilizarov group showed the mean bone defect length of 7.9 cm and mean soft tissue defect area of 41.4 cm 2. Thirteen patients in the unilateral group showed the mean bone defect length of 7.8 cm and the mean soft tissue defect area of 39.2 cm 2. The results of fracture healing, wound healing time, radiological consolidation index, external fixation index, Association for the Study and Application of the Method of Ilizarov (ASAMI) bone and lower-limb function score and incidence of complications were compared between the groups. Results:All patients were followed up for 24 to 60 months [(32.6±1.3)months]. Bone healing was achieved in all patients. The wound healing time was (2.7±2.3)days in Ilizarov group and (2.4±1.8)days in unilateral group ( P>0.05). The consolidation index was (43.4±8.7)d/cm in Ilizarov group and (45.8±10.3)d/cm in unilateral group ( P>0.05). The external fixation index was (52.6±8.9)d/cm in Ilizarov group and (58.7±12.9)d/cm in unilateral group ( P<0.05). The results of ASAMI bone score was excellent in 10 patients, good in 6, fair in 2 and poor in 1 in Ilizarov group, with the excellent rate of 84%; and excellent in 6 patients, good in 4, fair in 2, and poor in 1 in unilateral group, with the excellent rate of 77%, with insignificant difference between two groups ( P>0.05). The results of ASAMI lower-limb function score was excellent in 8 patients, good in 7, fair in 3, poor in 1 in Ilizarov group, with the excellent rate of 79%; and excellent in 6, good in 3, fair in 3, poor in 1 in unilateral group, with the excellent rate of 69%, with insignificant difference between the two groups ( P>0.05). Incidence of axial deviation was zero in Ilizarov group versus 23% in unilateral group ( P<0.05). After operation, Ilizarov group had refracture in 1 patient and pin site infection in 5, and unilateral group had refracture in 1 patient and pin site infection in 1, showing no significant difference between the two groups ( P>0.05). Conclusions:Tibial segmental bone defect with soft tissue defect can be effectively treated by open bone transport with Ilizarov and unilateral frame. Ilizarov frame has better biomechanical properties and is more convenient for correction of poor postoperative axial alignment.

Objective:To investigate the accuracy and postoperative efficacy of fluoroscopy and CT in measuring the mounting parameters of Taylor Spatial Frame.Methods:Data of patients with peripheral knee deformities who were treated by Taylor Spatial Frame from June 2006 to December 2017 were retrospectively analyzed. According to different measurement methods of mounting parameters, they were divided into fluoroscopy group (mounting parameters were obtained by intraoperative fluoroscopy) and CT group (mounting parameters were obtained by postoperative CT). There were 33 patients (35 segments) in the fluoroscopy group, 23 males (23 segments) and 10 females (12 segments), with an average age of 36.4±11.6 years old. In CT group, there were 30 patients, 19 males and 11 females, with an average age of 36.9±13.8 years. There were 22 cases (24 segments) of high tibial osteotomy, 5 cases (5 segments) of distal femur osteotomy, and 6 cases (6 segments) of both distal femur and high tibial osteotomy. Operation time, external fixation time, the number of electronic prescription and deformity correction time, mechanical axis deviation (MAD), medial proximal tibia angle (MPTA), mechanical lateral distal femoral angle (mLDFA), range of motion (ROM) andhospital for special surgery (HSS) knee functional scores were compared between the two groups.Results:All the 63 patients were followed up for 21.9 months (range, 12-60 months). In fluoroscopy group, operating time was 100.9±9.1 min, electronic prescription number 1.4±0.6, and deformity correction time was 19.4±3.6 days. In CT group, operating time was 79.2±10.8 min, electronic prescription number 1.2±0.4, and deformity correction time was 16.0±4.4 days. The difference of the above indexes between the two groups was statistically significant ( t=8.803, 2.042, 3.440, all P < 0.05). In the fluoroscopy group, the external fixation time was 4.8±0.9 months; MAD was 4.3±2.1 mm; MPTA was 88.5°±1.9°; mLDFA was knee 89.2°; ROM was 122.4°±3.9° and HSS score was 90.0±3.6. In CT group, the external fixation time was 4.6±0.9 months; MAD was 4.0±1.9 mm; MPTA was 87.8°±1.7°; mLDFA was knee 88.6°; ROM was 122.7°±3.4° and HSS score was 91.1±2.9. There was no statistically significant difference in the above indexes between the two groups (all P >0.05). In the fluoroscopy group, 22 segmental deformities were corrected by one electronic prescription, and 13 segmental deformities were corrected by two or more electronic prescriptions. In CT group, 25 segmental deformities were corrected by one electronic prescription, and 5 segmental deformities were corrected by two electronic prescriptions. There was no incision infection and no neurovascular injury in the two groups. Conclusion:Both fluoroscopy and CT scan can obtain the mounting parameters of the Taylor Spatial Frame, and the results of correction of the peripheral deformities of the knee joint are satisfactory. However, CT measurement of the mounting parameters is more accurate which could achieve shorter operation time, and less times of electronic prescriptions.

Objective To explore the impact of nutritional risk on short-term clinical outcomes after laparoscope-assisted radical gastrectomy for gastric cancer.Methods The retrospective case-control study was conducted.The clinical data of 150 patients who underwent laparoscopic gastrectomy at the First Affiliated Hospital of Wenzhou Medical University between June 2014 and April 2016 were collected.According to nutritional risk screening 2002 (NRS 2002),42 and 108 patients were respectively divided into the nutritional risk group (NRS 2002 score ≥3) and non-nutritional risk group (NRS 2002 score ＜3).Laparoscope-assisted radical subtotal gastrectomy or total gastrectomy was performed based on tumor location.Observation indicators:(1) postoperative short-term clinical outcomes:postoperative complications,duration of postoperative hospital stay,hospital expenses,unplanned readmission within 30 days after discharging.Postoperative complications meant total complications within 30 days postoperatively,grade Ⅰ-Ⅴ of Clavien-Dindo grade was complication classification.Grade Ⅱ and above of Clavien-Dindo grade were analyzed in this research.(2) Risk factors analysis affecting occurrence of postoperative complications of patients.Measurement data with normal distribution were represented as x±s and analyzed using the independent-sample t test.Measurement data with skewed distribution were described as M (Qn) and analyzed using the Mann-Whitney U test.Categorical variables were described as number and percentage and analyzed by the chisquare test.Ranked data were analyzed by the Mann-Whitney U test.Univariate analysis was done by the chi-square test.P＜0.1 of univariate analysis was used to multivariate analysis.COX regression model in multivariate analysis was built using progressive condition method.Results (1) Postoperative short-term clinical outcomes:number of patients with total complications,number of patients with severe complications,duration of postoperative hospital stay,hospital expenses and number of patients with unplanned readmission within 30 days after discharging were 9,2,11 days (9 days,16 days),57 825 yuan (51 894 yuan,66 908 yuan),2 in the nutritional risk group and 16,3,11 days (9 days,13 days),55 067 yuan (49 395 yuan,62 423 yuan),8 in the non-nutritional risk group,respectively,with no statistically significant difference between the 2 groups (X2=0.952,0.010,Z=-1.133,-1.691,X2 =0.048,P＞0.05).Results of univariate analysis showed that age was a risk factor affecting incidence of complications after laparoscope-assisted radical gastrectomy for gastric cancer (X2 =4.468,P＜ 0.05).Results of multivariate analysis showed that preoperative hypoproteinemia was an independent risk factor affecting incidence of complications after laparoscope-assisted radical gastrectomy for gastric cancer (OR =2.797,95％ confidence interval:1.053-7.435,P＜0.05).Conclusion There is little poor impact of nutritional risk on short-term outcomes after laparoscope-assisted radical gastrectomy for gastric cancer,preoperative hypoproteinemia is an independent risk factor affecting occurrence of grade Ⅱ and above of postoperative complications.

OBJECTIVETo explore the central mechanism of postoperative fatigue syndrome by detecting the expression of NMDA receptor and tryptophan metabolism.

METHODSAfter being numbered according to the weight, ninety-six male SD rats were randomly divided into control group (bowel loop was flipped after laparotomy and received intraperitoneal injection of saline at a dose of 1 ml/kg), POFS model(70% of the length of small intestine was resected and received intraperitoneal injection of saline at a dose of 1 ml/kg), and NMDA antagonist groups(70% of the length of small intestine was resected and received intraperitoneal injection of MK801 at a dose of 1 ml/kg). Each group was divided into subgroups by postoperative 1, 3, 5 and 7 d, with 8 rats in each subgroup. The hippocampus was removed at each time point after open field test (OFT) to detect the mRNA expression levels of NMDA receptor 1 and kynurenine aminotransferase III((KATIII() by real-time PCR. Protein level of NMDA receptor 1 was detected by Western blot. High performance liquid chromatography (HPLC) was used to measure the concentrations of tryptophan (TRP), kynurenine (KYN) and kynurenic acid(KYNA). Ultra-structural changes of hippocampal neurons were observed by transmission electron microscopy(TEM).

RESULTSAs compared to control group, exercise score decreased(P<0.05), rest time and central panel residence time prolonged, periphery/central panel ratio increased (all P<0.05), mRNA and protein expressions of NMDA receptor 1 increased (P<0.05), mRNA expression of KAT III( decreased (P<0.05), KYN/TRP ratio and KYN/KYNA ratio decreased (all P<0.05) in POFS group on postoperative day 1 and 3. As compared to POFS group, central panel residence time and periphery/central panel ratio decreased on postoperative day 1, and mRNA and protein expressions of NMDA receptor 1 decreased on postoperative day 1 and 3 (all P<0.05) in antagonist group. TEM revealed that degenerated neuron was found in the hippocampus of POFS rats, while such damage was improved in antagonist group.

CONCLUSIONThe increased expression level of NMDA receptor may play an important role in POFS. NMDA receptor antagonist MK801 may improve the POFS.
