Literature analysis,expert consultation,case analysis and other methods were used to establish a public hospital specialty operation evaluation system suitable for high-quality development,including 2 first-level indicators of medical ability and economic operation and 13 second-level indicators.Urology surgery in the pilot hospital was taken as an example to carry out surgical operation effect evaluation.To strengthen the evaluation of public hospital specialized operation,it should pay attention to the evaluation of medical capacity,strengthen the cooperation of functional departments,and improve the supporting policies of operation,for better promoting the development of high-quality operation of hospitals.

Objective:To explore the diagnosis and treatment of lymphoepithelioma-like intrahepatic cholangiocarcinoma(LEL-ICC).Methods:The retrospective and descriptive study was conducted. The data of 7 patients with pathological diagnosis of LEL-ICC after hepatectomy who were treated in Lishui Central Hospital in Zhejiang Province from December 1, 2009 to January 30, 2024 were collected. There were 2 males and 5 females. The age range was from 40 to 64 years old, with a median age of 52 years old. All 7 patients showed no obvious clinical symptoms.We analysed the imaging manifestations, pathological features, treatmentsand prognoses of patients.Postoperative follow-upswere conducted via telephone, with a focus on whether the patient had relapsed. The deadline was February 20, 2024.Results:Five cases underwent ultrasound examination, of which 4 cases showed hypoechogenicity and 1 case showed hyperechogenicity. 7 cases underwent MRI examination, showing low signal on T1WI, high signal on T2WI, and high signal on diffusion-weighted imaging. 2 cases had type A enhancement, 2 cases had type B enhancement, and 3 cases had type C enhancement. All 7 cases received surgical treatment, 2 cases were received prophylactic transarterial chemoembolization (TACE) after surgery, and 3 cases were received systemic chemotherapy after surgery; All 7 cases underwent postoperative follow-up, with a follow-up time of 1-166 months and a median follow-up time of 56 months. One case developed hilar and retroperitoneal lymph node metastasis after surgery for 6 months, and underwent surgical treatment. After surgery, chemotherapy was performed. 25 months later, right adrenal gland metastasis reappeared, and after combined treatment, the metastatic lesion was reduced and the patient received surgical treatment and chemotherapy, and there is currently no recurrence. The remaining 6 cases showed no recurrence.Conclusions:LEL-ICC lacks specific clinical symptoms and imaging manifestations, diagnosis relies on histopathological and immunohistochemical examinations. Comprehensive treatment with surgical intervention as the main approach can lead to better prognosis for patients.

Objective:To explore the clinical manifestations, diagnosis and treatment methods, and prognosis of hepatic portal venous gas (HPVG).Methods:Retrospective case analysis was used in the case data of 7 patients with HPVG, who were treated in Lishui Central Hospital from January 2017 to July 2024, including 5 males and 2 females. Age ranged from 46 to 90 years, with an average age of 69 years. Abdominal pain was the first manifestation in 6 cases, and septic shock occurred in 2 cases. The initial symptoms, primary diseases, comorbidities, laboratory results, imaging examinations, treatment plans, and prognosis were analyzed. Prognostic follow-up was conducted by telephone, with the focus on whether the patient had experienced HPVG recurrence and postoperative complications. The deadline for follow-up was July 31, 2024.Results:All patients had elevated white blood cells and C-reactive protein (CRP), and prothrombin time was prolonged in 4 patients. pH and base excess decreased in 4 cases, and lactic acid increased in 5 cases. Alanine aminotransferase increased in 2 cases, and total bilirubin increased in 3 cases. Blood culture was positive in 3 cases. Contrast-enhanced abdominal CT showed clear gas shadows in the portal vein and its branches in all 7 cases, which were confined to the left liver in 4 cases and distributed in both sides of the liver in 3 cases. The primary diseases were intestinal obstruction and necrosis in 4 cases, intestinal perforation and necrosis in 1 case, inflammatory bowel disease in 1 case, and acute pancreatitis in 1 case. Five patients were complicated with hypertension, diabetes and other diseases. Two patients received surgical treatment, and the average time from surgery to diagnosis was 6.8 h. Five cases received conservative treatment, 2 cases were cured and 3 cases died, with an average time from onset to death of 21.2 h.Conclusions:Contrast-enhanced abdominal CT should be the preferred method for the diagnosis of HPVG. The primary disease and its severity should be fully evaluated in the treatment of HPVG. Patients with intestinal necrosis should undergo laparotomy as soon as possible, and enterostomy should be performed during the operation. Clinicians should strengthen the awareness of HPVG in order to improve the prognosis of patients.

Background Tributyl phosphate (TBP) is widely used as an organophosphate flame retardant. However, there are limited studies on the toxicity of TBP to aquatic organisms at low levels of exposure. Objective To investigate the effects of TBP on early development of zebrafish (Danio rerio). Methods Zebrafish embryos were randomly divided into four groups at 2 h post-fertilisation (2 hpf), namely, the 0.01% dimethyl sulfoxide (DMSO) control group and TBP exposure groups (0.02, 0.2 and 2 μg·L⁻¹). The exposure time was from 2 hpf to 120 hpf and the hatching rate, malformation rate, heart rate and body length of zebrafish embryos at 72 hpf, the frequency of tail curling at 24-29 hpf, the locomotor ability at 96 hpf and the survival rate at 120 hpf were evaluated, respectively. The whole-body triiodothyronine (T₃) and tetraiodothyronine (T₄) levels of juvenile fish were measured by enzyme immunoassay at the end of the infection, and the expression levels of hypothalamic-pituitary-thyroid axis (HPT) and neurodevelopmental-related genes were detected by quantitative real-time PCR (q-PCR). Results The heart rates of zebrafish embryos were significantly decreased in all TBP-treated groups (P<0.001), the survival rates of the 0.02 and 2 μg·L⁻¹ TBP groups were significantly decreased (P<0.05), and the malformation rate of the 2 μg·L⁻¹ treated group was significantly increased (P<0.05), which was mainly manifested by pericardial oedema. The frequency of tail curling of zebrafish embryos in all groups reached the highest at 25 hpf, which was significantly lower (P<0.001) in all exposure groups than in the control group (P<0.001). In the locomotor behaviour experiments, the swimming speed of zebrafish larvae in the dark cycle was significantly decreased in the 0.02 and 0.2 μg·L⁻¹ TBP groups (P<0.05), and similar results were found for the light cycle in the 0.2 and 2 μg·L⁻¹ TBP groups (P<0.05). Compared with the control group, the T₃ level of zebrafish juveniles in the 0.2 μg·L⁻¹ TBP group increased significantly (P<0.05). The q-PCR results showed that the expression levels of HTP axis-related genes [thyroid hormone receptors (trα, \begin{document}$tr\beta $\end{document}), thyroglobulin (tg), and sodium/iodide co-transporter (nis)] were significantly down-regulated in the exposure groups, the expression level of transthyretin (ttr) was significantly up-regulated in the 0.02 μg·L⁻¹ TBP group, and the iodothyronine deiodinase 2 (dio2) expression level was significantly down-regulated in the 0.02 μg·L⁻¹ TBP group (P<0.05); the neurodevelopment-related gene acetylcholinesterase (ache) was significantly down-regulated in the exposure groups, and the expression levels of myelin basic protein (mbp) and Elav like neuron-specific RNA binding protein 3 (elavl3) were significantly down-regulated in the 0.02 μg·L⁻¹ TBP group (P<0.05). Conclusion TBP exposure can lead to early developmental abnormalities in zebrafish, manifested as developmental toxicity, thyroid endocrine disruption and neurotoxicity during hatching and early juvenile stages.

Background The concentrations of disinfection by-products (DBPs) are varied by different water sources, disinfectants, or treatment processes in Wuxi, and the associated health risks are also different. Objective To understand the levels of trihalomethanes (THMs) and haloacetamides (HAcAms) in drinking water in Wuxi, and their variations by water sources, seasons, disinfectants or treatment processes, aiming to provide technical support for ensuring the safety of drinking water. Methods In dry period (December 2019) and wet period (July 2020), the finished water and tap water (from the beginning, middle, and end of the drinking water distribution network) from 12 centralized water treatment plants in Wuxi were collected to detect the concentrations of THMs and HAcAms in water samples. A purge and trap-gas chromatography-mass spectrometry method was applied to detect trichloromethane (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and tribromomethane (TBM), and a solid-phase extraction-gas chromatography-mass spectrometry method to detect dichloroacetamide (DCAcAm), trichloroacetamide (TCAcAm), bromochloroacetamide (BCAcAm), dibromoacetamide (DBAcAm), bromodichloroacetamide (BDCAcAm), dibromochloroacetamide (DBCAcAm), and tribromoacetamide (TBAcAm). Analyses and comparisons were made on the concentrations of THMs and HAcAms in drinking water by water sources (the Yangtze River/the Taihu Lake/reservoir), wet/dry seasons, disinfection methods (liquid chlorine/sodium hypochlorite), and treatment processes (conventional treatment/conventional+advanced treatment). Results A total of 96 drinking water samples were collected in Wuxi. THMs were positive in all the water samples (100%), with concentration ranging from 1.027 to 40.225 μg·L⁻¹ and the M (P₂₅, P₇₅) concentration being 24.782 (17.784, 30.932) μg·L⁻¹. None of the 4 THMs exceeded the standard limit of the Standards for drinking water quality (GB 5749-2022 ), and the order of the 4 THMs concentrations from high to low was TCM > BDCM > DBCM > TBM. Five of the 7 HAcAms were detected, the total concentration ranged from 0.137 to 3.288 μg·L⁻¹, and the M (P₂₅, P₇₅) was 0.808 (0.482, 1.704) μg·L⁻¹. The DCAcAm concentration was the highest (2.448 μg·L⁻¹), followed by BCAcAm, while TCAcAm and DBCAcAm were not detected. The M (P₂₅, P₇₅) of the total concentration of THMs in the drinking water from the Taihu Lake was 33.353 (26.649, 36.217) μg·L⁻¹, that of the Yangtze River was 27.448 (24.312, 31.393) μg·L⁻¹, and both were higher than the level of the reservoir [16.359 (2.305, 21.553) μg·L⁻¹] (P<0.05), while the M (P₂₅, P₇₅) of the total concentration of HAcAms in the drinking water from the Taihu Lake was 0.616 (0.363, 0.718) μg·L⁻¹, which was lower than those of the Yangtze River [0.967 (0.355, 2.283) μg·L⁻¹] and the reservoir [1.071 (0.686, 1.828) μg·L⁻¹] (P<0.05). There were no statistically significant differences in the total concentrations of THMs and HAcAms between wet season and dry season, or between different disinfection methods (P>0.05). The M (P₂₅, P₇₅) concentrations of THMs and HAcAms in drinking water after advanced treatment process involving ozone, activated carbon, and membrane were 20.565 (3.316, 27.185) μg·L⁻¹ and 0.623 (0.452, 1.286) μg·L⁻¹ respectively, and were lower than the corresponding values after conventional treatment process, 28.740 (23.431, 35.085) μg·L⁻¹ and 0.934 (0.490, 2.116) μg·L⁻¹ respectively (P＜0.05). Conclusion The concentrations of THMs and HAcAms in drinking water in Wuxi are generally at a low level. The levels of controlled THMs meet the requirements of national standards, and the levels of uncontrolled HAcAms as new DBPs are up to μg·L⁻¹. The concentrations of the two kinds of DBPs in drinking water vary by water sources. The concentrations of THMs and HAcAms produced by the advanced treatment process are lower than that by the conventional treatment process.

Objective:To study the results of using a sequential menagement of conservative treatment, percutaneous transhepatic cholangial drainage(PTCD), laparoscopic cholecystectomy(LC) combined with laparoscopic common bile duct exploration(LCBDE) and primary duce closure(PDC) in patients with cholecystolithiasis and common bile duct stone(CBDS) who presented with acute cholangitis.Methods:The clinical data of 397 patients with CBDS and cholecystolithiasis who presented with acute cholangitis from January 2015 to August 2020 were retrospectively analyzed, including 230 patients from the West Campus, Beijing Chaoyang Hospital, Capital Medical University, 95 patients from the Second People's Hospital of Binzhou and 72 patients from Rizhao Central Hospital. Conservative treatment, PTCD and LC+ LCBDE+ PDC were used sequentially. The interval between PTCD and LCBDE, the decrease of serum total bilirubin and alanine aminotransferase after PTCD, the operative time of LC+ LCBDE+ PDC, and the intraoperative blood loss were analyzed. Postoperative indwelling time of abdominal drainage tube and PTCD tube time, postoperative hospital stay, postoperative complications, etc.Results:These were 15 males and 18 femals with the mean age of 57.5 years old. The mean serum total bilirubin and alanine aminotransferase levels decreased from (148.3±36.8) μmol/L and (172.6±26.9) U/L before PTCD to (32.6±5.9) μmol/L and (45.7±7.2) U/L after PTCD, respectively. The interval between PTCD and LCBDE was (25.3±2.6) d. The operation time of LC+ LCBDE+ PDC was (95.4±14.2) min. The intraoperative blood loss was (35.2±9.5 )ml and the mean postoperative hospital stay was (12.4±3.5) d. The postoperative indwelling time of abdominal drainage tubes and PTCD tubes were (10.6±2.3) d and (25.8±4.7) d, respectively. After surgery, bile leakage occurred in 3 patients (9.1%), abdominal hemorrhage in 1 patient (3.0%), biliary bleeding in 1 patient (3.0%), navel incision infection in 1 patient (3.0%), lower common bile duct stenosis in 2 patients (6.1%). All complications responded well to conservation treatment.Conclusions:Sequential treatment using conservative treatment, PTCD combined with LC+ LCBDE+ PDC in patients with cholecystolithiasis and CBDS who presented with acute cholangitis was safe, and efficacious using the minimally invasive approach. This approach is worth promoting to other centers.

Objective:To summarize the clinical experience of transurethral columnar balloon dilation of prostate (TUCBDP) in the treatment of patients with benign prostatic hyperplasia(BPH).Methods:A retrospective analysis of 379 BPH clinical data from the Hubei Provincial Hospital of Traditional Chinese Medicine using TUCBDP was performed between June 2015 and June 2018.Their age was (71.3±14.5)years old. The history of disease ranged from 1 month to 36 years. The prostate volume was(47.4±2.1) ml. Preoperative maximum urinary flow rate was (Q max)(9±4) ml/s, postvoid residual urine(PVR) was (123.1±72.4) ml. Their international prostate symptom score (IPSS) was (21±6) points. The quality of life score (QOL)was (5±1) points. The international index erectile function questionnaire (IIEF-5)in 32 patients, who had sex before surgery, was 15±4. We set the time of catheter structure improvement in June 2016 as the boundary, including the early stage (June 2015 to May 2016, 121 cases) and the recent stage (June 2016 to June 2018, 258 patients). In the early stage, the principle of operation is the inner balloon of the catheter to dilate the membrane urethra, and the outer balloon to dilate the urethra of the prostate and the bladder neck. The main surgical steps include the insertion of a dilatation catheter, localization by touching the skin of the scrotum bottom, the inner and outer balloon are filled with water, the first time of drainage and decompression in the inner and outer balloon, the catheter continuous irrigation, drainage and decompression of the inner and outer balloon again, removing the dilatation catheter, and the ordinary urinary catheter was replaced and continuous irrigation. In the recent stage, the principle of surgery is that the inner balloon only served for positioning and fixation. The outer balloon is used to dilate the membrane urethra, prostate urethra, and bladder neck. The inner and outer balloon are drained and decompressed at one time after surgery. The main surgical steps are that the resectoscope was used to examine the bladder and urethra and to guide the dilatation catheter into the bladder. The apex of the prostate touching was used to conform the location. The inner balloon water filling was used for fix the positioning. The inner and outer balloon are filled with water, decompressed and pulled out for urination test, the gland expansion is observed under the resectoscope, and ordinary urinary catheter is replaced for continuous flushing. We observed the changes in Q max, PVR, IPSS, and QOL at 1, 3, 6, 12, and 24 months after the operation. the complications differences in two-stage patien, including the International Incontinence Advisory Committee Urinary Incontinence Questionnaire (ICI-Q-SF) score; those who had sex before surgery were recorded changes in the IIEF-5 score, was compared. Results:There were no deaths during and after operation in this study. The operation time was (18.5±6.7) min. The number of follow-up cases at 1, 3, 6, 12, and 24 months after operation were 326, 253, 201, 194, and 181, respectively. The Q max at 1, 3, 6, 12, and 24 months after operation were (17±9)ml/s, (15±2)ml/s, (12±4)ml/s, (13±6)ml/s and (13±4)ml/s, respectively. The PVR were (17.4± 11.6) ml, (20.6±9.8)ml, (25.4±13.1)ml, (31.5±11.5)ml, and (29.1±12.4)ml, respectively. The IPSS were(7±5) points, (4±4) points, (4±4) points, (6±5) points, (4±4) points, respectively. The QOL were (2±1) points, (2±1) points, (2±1) points, (2±1) points, and (2±1), respectively. All those results that were significantly different from those before surgery ( P<0.05). There were 32 patients who had sex before the operation. The postoperative IIEF-5 score was (17± 6), which was not significantly different from that before the operation ( P>0.05). Two patients had transient retrograde ejaculation, which relieved spontaneously within the 6 month. 4 cases with pseudourinary incontinence in the recent stage (1.5%) were not statistically different from 6 cases (4.9%) in the early stage ( P>0.05). one case(0.4%) of major bleeding in the recent stage was statistically different from 6 cases (4.9%) in the early stage ( P<0.05). 2 cases (0.7%) of patients with acute urinary retention in the recent stage were significantly different from 15 cases (12.4%) in the early stage ( P<0.05). Conclusions:TUCBDP has a positive overall effect and high safety. The major complications of surgery in the recent stage, except for pseudo-urinary incontinence, are significantly lower than that in the early stage, which may be related to the improvement of the catheter structure and the accumulation of clinical experience.

Background: Most patients including health care workers (HCWs) survived the coronavirus disease 2019 (COVID-19), however, knowledge about the sequelae of COVID-19 after discharge remains limited. Methods: A prospectively observational 3-month follow-up study evaluated symptoms, dynamic changes of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) IgG and IgM, lung function, and high resolution computed tomography (HRCT) of survivors of COVID-19 after discharge at Wuhan Union Hospital, China. Results: Seventy-six survivors (55 females) with a mean age of 41.3 ± 13.8 years were enrolled, and 65 (86%) were HCWs. A total of 69 (91%) patients had returned to their original work at 3-months after discharge. Most of the survivors had symptoms including fever, sputum production, fatigue, diarrhea, dyspnea, cough, chest tightness on exertion and palpitations in the three months after discharge. The serum troponin-I levels during the acute illness showed high correlation with the symptom of fatigue after hospital discharge (r = 0.782; P = 0.008) and lymphopenia was correlated with the symptoms of chest tightness and palpitations on exertion of patients after hospital discharge (r = −0.285, P = 0.027; r = −0.363, P = 0.004, respectively). The mean values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC, total lung capacity and diffusion capacity were all normal (> 80% predicted) and lung HRCTs returned to normal in most of the patients (82%), however, 42% of survivors had mild pulmonary function abnormalities at 3-months after discharge. SARS-CoV-2 IgG turned negative in 11% (6 of 57 patients), 8% (4 of 52 patients) and 13% (7 of 55 patients), and SARS-CoV-2 IgM turned negative in 72% (41 of 57 patients), 85% (44 of 52 patients) and 87% (48 of 55 patients) at 1-month, 2-months and 3-months after discharge, respectively. Conclusion Infection by SARS-CoV-2 caused some mild impairments of survivors within the first three months of their discharge and the duration of SARS-CoV-2 antibody was limited, which indicates the necessity of long-term follow-up of survivors of COVID-19.

Objective To investigate the relationship between subgroups of central lymph node metastasis (sCLNM) and lateral lymph node metastasis (LNM) of unilatal papillary thyroid carcinoma (uPTC) with cervical lymph node negative(cN0).Methods The clinical and pathological data of 161 patients with cN0-uPTC who underwent total thyroidectomy+central lymph node dissection+lateral lymph node dissection from Jan.2016 to Dec.2016 were retrospectively analyzed.The relationship between the lymph node metastasis of each subarea in the central area of the affected side and the lymph node metastasis of the affected side was investigated.Results Binary logistic regression analysis of cN0-uPTC subregions in the affected central region showed:pre-laryngeal lymph node metastasis,pre-tracheal lymph node metastasis and paratracheal lymph node metastasis were independent risk factors for lymph node metastasis in the affected lateral region(P=0.008,0.016,0.035,respectively).Prelaryngeal lymph node metastasis was an independent risk factor for lymph node metastasis in the affected area Ⅱ (P=0.015).Pre-tracheal lymph node metastasis was an independent risk factor for lymph node metastasis in affected area Ⅲ (P=0.004).Pre-tracheal and para-tracheal lymph node metastasis were independent risk factors for lymph node metastasis in the affected Ⅳ area (P=0.035,0.011,respectively).Conclusions The lymph node metastasis pathway of thyroid cancer had certain regularity.The pre-laryngeal lymph node metastasis has the prediction value for the lymph node metastasis of the affected area Ⅱ.The pre-tracheal lymph node metastasis has the prediction value for the lymph node metastasis of the affected area Ⅲ.The pre-tracheal and paratracheal lymph node metastasis have the prediction value for lymph node metastasis of the affected area Ⅳ.Lymph node dissection in affected areas Ⅲ and Ⅳ needs to be considered in patients with pre-tracheal or paratracheal lymph node metastases.On this basis,lymph node dissection on the affected areas Ⅱ,Ⅲ,and Ⅳ might be considered if there is pre-laryngeal lymph node metastasis at the same time.
