Objective To explore the technical process and clinical application of laparoscopic combined upper midline incision minimally invasive liver transplantation. Methods A retrospective analysis was conducted on 30 cases of laparoscopic combined upper midline incision minimally invasive liver transplantation. The cases were divided into cirrhosis group (15 cases) and liver failure group (15 cases) based on the primary disease. The surgical and postoperative conditions of the two groups were compared. Results All patients successfully underwent laparoscopic "clockwise" liver resection, with no cases of passive conversion to open surgery or intolerance to pneumoperitoneum. In 6 cases, the right lobe was relatively large, and the right hepatic ligaments could not be completely mobilized. One case required an additional reverse "L" incision during open surgery. All patients successfully completed the liver transplantation, with no major intraoperative bleeding, cardiovascular events, or other occurrences in the 30 patients. The model for end-stage liver disease (MELD) score in the cirrhosis group was lower than that in the liver failure group (P<0.001). There were no statistically significant differences between the two groups in terms of age, surgical time, blood loss, anhepatic phase, or cold ischemia time (all P>0.05). During the perioperative period, there was 1 case of hepatic artery embolism, 1 case of portal vein anastomotic stenosis, no complications of hepatic vein and inferior vena cava, and 3 cases of biliary anastomotic stenosis, all of which occurred in the liver failure group. Conclusions In strictly selected cases, the minimally invasive liver transplantation technique combining laparoscopic hepatectomy with upper midline incision for graft implantation has the advantages of smaller incisions, less bleeding, relatively easier operation, and faster postoperative recovery, which is worthy of clinical promotion and application.

Objective:To predict the molecular mechanism of Biminkang Granules in the treatment of allergic rhinitis using network pharmacological methods combined with animal experiments.Methods:Active component targets and allergic rhinitis targets were screened from TCMSP, OMIM, GeneCards, TTD, DrugBank and PharmGKB databases; R language software was used to map the intersection of drug and disease targets; Cytoscape software and String platform were used to construct intersection target PPI network and conduct network topology analysis; DAVID platform was used to perform GO enrichment and KEGG pathway analysis, and perform molecular docking verification on the main active components and key targets. 32 rats were divided into a blank group of 8 and a model group of 24 using a random number table method. Model rats were induced by ovalbumin to establish an allergic rhinitis model. 24 SD rats that were successfully modeled and were randomly divided into model group, Western medicine group, and Biminkang Granules group using a random number table method, with 8 rats in each group. The Western medicine group was gavaged with 1 mg/kg of loratadine solution, the Biminkang Granules group was gavaged with 4.1 g/kg of Biminkang Granules solution, and the blank group and model group rats were gavaged with the same volume of physiological saline once a day for 2 consecutive weeks. The symptoms of rhinitis in each group of rats for 30 minutes were observed and recorded, and the pathological changes of the rat nasal mucosa were observed using HE staining. ELISA method was used to detect the levels of IL-17 and IL-6 in rat serum, and Western blot method was used to determine the expressions of TNF and STAT3 proteins in rat tissues.Results:A total of 41 target proteins of BiMinKang Dranule in the treatment of allergic rhinitis were predicted, and TNF, STAT3 and other core target proteins were obtained by PPI network topology analysis. The biological process of GO involved drug response, inflammatory response, cytokine response, etc.KEGG enrichment is involved in Th17 cell differentiation, lipid and atherosclerosis, IL-17, toll-like receptor and other pathways. Molecular docking results indicated that the main active components had good binding activity to key target proteins.Animal experiments showed that BiMinKang Dranule could improve the inflammatory symptoms of allergic rhinitis rats, down-regulate the expression of IL-17 and IL-6 in blood, and inhibit the expression of TNF and STAT3 proteins.Conclusion:Biminkang Granules can treat allergic rhinitis through multiple active components, multiple target proteins and multiple pathways, and the mechanism may be related to the regulation of Th17 cell differentiation pathway related proteins.

Objective:To investigate the anatomic classification and reconstruction of right intrahepatic bile duct in the donor liver of split liver transplantation (SLT).Methods:The retrospective and descriptive study was constructed. The clinical data of 85 patients who underwent SLT in the Third Affiliated Hospital of Sun Yat-sen University from July 2014 to January 2022 were collected. There were 65 males and 20 females, aged 45(range, 1-82)years. Observation indicators: (1) surgical conditions; (2) anatomy of right intrahepatic bile duct; (3) bile duct reconstruction; (4) postoperative biliary complications; (5) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range) or M( Q1, Q3).Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Surgical conditions. Of the 85 donor livers, 11 donor livers were split between the left and right hemilivers, and 74 donor livers were split between the classic right trilobe and left lateral lobe. The cold ischemia time of 85 donor livers was 291(273, 354)minutes, and the operation time, anhepatic phase time and volume of intraoperative blood transfusion of 85 recipients were (497±97)minutes, 51(40, 80)minutes and 8(7, 12)U. (2) Anatomy of right intrahepatic bile duct. Of the 85 donor livers, there were 47 donor livers with classic bile duct anatomical model (type 1), of the ratio as 55.3%(47/85), and 38 donor livers with anatomical variants, of the ratio as 44.7%(38/85). Of the 38 donor livers with anatomical variants, 7 donor livers were type 2, 16 donor livers were type 3a, 2 donor livers were type 3b, 2 donor livers were type 3c, 1 donor liver was type 4, 3 donor livers were type 5a, 4 donor livers were type 5b, 3 donor livers were type 6. For bile duct splitting patterns of the 85 donor livers, 84 donor livers were split with the main trunk of common hepatic duct preserving in the right hemiliver or right trilobe, and 1 donor liver were treated with complete left and right hemiliver splitting to preserve the main trunk of the common hepatic duct in the left hemiliver and the right hemiliver in the right hepatic duct (type 1 bile duct anatomical model). There were 84 donor livers with only one bile duct opening, and 1 donor liver with two bile duct openings (type 3c bile duct anatomical model). (3) Bile duct reconstruction. Of the 85 recipients, there were 69 recipients with common bile duct end-to-end anastomosis to common bile duct of donor liver (38 donor livers with type 1 bile duct anatomical model, 5 donor livers with type 2 bile duct anatomical model, 14 donor livers with type 3a bile duct anatomical model, 2 donor livers with type 3b bile duct anatomical model, 1 donor liver with type 4 bile duct anatomical model, 3 donor livers with type 5a bile duct anatomical model, 4 donor livers with type 5b bile duct anatomical model, 2 donor livers with type 6 bile duct anatomical model), 11 recipients with jejunum anastomosis to common bile duct of donor liver (7 donor livers with type 1 bile duct anatomical model, 2 donor livers with type 2 bile duct anatomical model, 1 donor liver with type 3c bile duct anatomical model, 1 donor liver with type 6 bile duct anatomical model), 3 recipients with jejunum anastomosis to common hepatic duct of donor liver (1 donor liver with type 1 bile duct anatomical model, 2 donor livers with type 3a bile duct anatomical model), 1 recipient with jejunum anastomosis to right hepatic duct of donor liver (type 1 bile duct anatomical model), 1 recipient with common hepatic duct end-to-end anastomosis to right posterior branch of donor liver combined with jejunum of the recipient Roux-en-y anastomosis to common hepatic duct of donor liver (type 3c bile duct anatomical model). (4) Postoperative biliary complications. Of the 85 recipients, 6 cases had postoperative biliary complications, with an incidence of 7.1% (6/85). Of the 6 recipients with postoperative biliary complications, there were 5 recipients with donor liver with type 1 bile duct anatomical model, including 3 cases undergoing postoperative biliary stricture with biliary leakage and 2 cases undergoing postoperative biliary anastomotic stricture, 1 recipient with donor liver with type 3b bile duct anatomical model and undergoing postoperative biliary anastomotic stricture and bile leakage in the liver section. Cases with biliary complications were 5 in the 47 recipients with donor liver with classic bile duct anatomical model and 1 in the 38 recipients with donor liver with anato-mical variants, showing no significant difference between them ( P>0.05). (5) Follow-up. There were 83 recipients receiving followed up for 52(12,96)months. During the follow-up period, 2 recipients died due to non-biliary complication factors (1 donor liver with type 1 bile duct anatomical model and 1 donor liver with 3a bile duct anatomical model). Conclusion:The anatomical classification of right intrahepatic bile duct of donor liver in SLT is mainly classical bile duct anatomical model, and the bile duct reconstruction scheme is mainly common bile duct of donor liver end-to-end anasto-mosis to common bile duct of recipient.

β2-adrenergic receptor （β2-AR） agonists are widely used as first-line drugs in the treatment of bronchial asthma （hereinafter referred to as “asthma”）， but long-term use can lead to β2-AR desensitization and reduce its clinical efficacy， resulting in poor symptom control of some asthma patients. The mechanism of β2-AR desensitization induced by β2-AR agonists mainly includes slow hyposensitization （related to the decrease of β2-AR density in airway mucosa） and rapid hyposensitization （related to the mechanism of stimulatory G protein decoupling）. Cyclic adenosine monophosphate（cAMP）-protein kinase A and cAMP- exchange protein activated by cAMP signaling pathways are closely related to β2-AR desensitization. Glucocorticoids， peroxisome proliferator-activated receptor-gamma agonists， ASM-024， Chinese medicine monotherapies and formulations， when combined with β2-AR agonists， can improve the sensitivity of β2-AR， so as to better control asthma symptoms.

OBJECTIVE To investigate the effects of 3 different primitives or the same primitives with different characters of Tibetan medicine Zuomoxing[Caragana changduenais Liou f. with red heartwood, Caragana jubata(Pall.) Poir. with brown and white heartwood] on rats with pattern of toxic heat-induced blood stasis. METHODS　Ninety SD rats were randomly divided into the blank group, model group, aspirin-positive group, Changdu low-dose group(CDD), Changdu high-dose group(CDG), whitewood of Guijian low-dose group(GJBD), whitewood of Guijian high-dose group(GJBG), brown wood of Guijian low-dose group(GJZD), Brown wood of Guijian high-dose group(GJZG). Models with heat toxicity and blood stasis pattern were established by intraabdominal injection of carrageenan combined with tail vein injection of lipopolysaccharide. The effects of each group on blood rheology, coagulation four indices and blood routine were determined, and the content of arachidonic acid(AA), IL-1β, IL-6, TNF-α and thromboxane B2(TXB2) were measured with ELISA. RESULTS ①Blood rheology: Compared with model group, CDD and CDG significantly decreased whole blood viscosity(WBV), reduction viscosity of whole blood(WBRV), erythrocyte rigidity index(HGX), erythrocyte deformability index(EDI), whole blood relative index(WBRI) (P<0.01), and increased plasma viscosity(P<0.01). GJZG and GJZD significantly decreased HGX(P<0.01 or P<0.05), and increased plasma viscosity(P<0.01). GJBG and GJBG significantly decreased WBHSV, WBHSRV, HGX, EDI, and whole blood high shear relative index(WBHSRI)(P<0.01). ②Coagulation four indices: Compared with model group, CDD significantly reduced the thrombin time(TT)(P<0.01). GJZG significantly reduced activated partial thromboplastin time(APTT) and TT(P<0.01 or P<0.05). GJBD significantly reduced prothrombin time(PT) and APTT (P<0.01 or P<0.05). ③Blood routine: Compared with model group, GJZD and GJBD significantly decreased the percentage of monocytes(P<0.01 or P<0.05). The number of large platelets in CDD significantly increased(P<0.05). CDG significantly increased the platelet number, platelet hematocrit, and large platelet number(P<0.01 or P<0.05), and tended which to be normal. ④Inflammatory factors: Compared with model group, the levels of TNF-α, IL-6, TXB2 were significantly increased in CDD and CDG(P<0.01 or P<0.05). The levels of IL-6 and TXB2 were significantly increased in GJZD and GJZG(P<0.01). GJBD was significantly increased TXB2(P<0.01), and GJBG was significantly increased IL-1β, IL-6, and TXB2(P<0.01), while decreased AA(P<0.05). CONCLUSION Zuomoxing with separate sources have different degrees of effects on rats with pattern of toxic heat-induced blood stasis, and have different degrees of effects on hemorheology, coagulation factors, blood routine and inflammatory mediators, and the degree and trend of effects are different with different doses. The effect of promoting blood circulation and removing blood stasis was generally manifested as Changdu > whitewood of Guijian > Brown wood of Guijian. The effect of promoting blood circulation and removing blood stasis may be the result of multiple pathways and mechanisms.

Objective To investigate immunogenic and toxic effects of graphene oxide (GO) nanoparticles in mouse skeletal muscles and in human blood in vitro. Methods GO nanoparticles prepared using a probe sonicator were supended in deionized H2O or PBS, and particle size and surface charge of the nanoparticles were measured with dynamic light scattering (DLS). Different concentrations (0.5, 1.0 and 2.0 mg/mL) of GO suspension or PBS were injected at multiple sites in the gastrocnemius muscle (GN) of C57BL/6 mice, and inflammatory response and immune cell infiltrations were detected with HE and immunofluorescence staining. We also examined the effects of GO nanoparticles on human red blood cell (RBC) morphology, hemolysis and blood coagulation using scanning electron microscope (SEM), spectrophotometry, and thromboelastography (TEG). Results GO nanoparticles suspended in PBS exhibited better colloidal dispersity, stability and surface charge effects than those in deionized H2O. In mouse GNs, injection of GO suspensions dose- and time-dependently resulted in sustained muscular inflammation and myofiber degeneration at the injection sites, which lasted till 8 weeks after the injection; immunofluorescence staining revealed obvious infiltration of monocytes, macrophages, dendritic cells and CD4+T cells around the injection sites in mouse GNs. In human RBCs, incubation with GO suspensions at 0.2, 2.0 and 20 mg/mL, but not at 0.002 or 0.02 mg/mL, caused significant alterations of cell morphology and hemolysis. TEG analysis showed significant abnormalities of blood coagulation parameters following treatment with high concentrations of GO. Conclusion GO nanoparticles can induce sustained inflammatory and immunological responses in mouse GNs and cause RBC hemolysis and blood coagulation impairment, suggesting its muscular toxicity and hematotoxicity at high concentrations.

[Objective]This study aimed to improve the existing semen processing methods in the field of reproductive male medicine,particularly focusing on the 300×g 20 min treatment condition in the double-layer density gradient method,to enhance fertilization outcome.[Methods]Semen specimens from 1623 patients undergoing assisted reproductive techniques at the Reproductive Medicine Center of the Sixth Affiliated Hospital of Sun Yat-sen University from July and September 2020 and March and May 2022 were collected for preliminary experiments.Four different double-layer density gradient methods(200×g 10 min,200×g 20 min,300×g 10 min,and 300×g 20 min)were compared for sperm DNA fragmentation rates and recovery rates after processing.Subsequently,the optimal method was selected as the new approach and compared with the current method in use(300×g 20 min double-layer gradient method)to assess any statistical differences in fertilization rates.Further optimization to a single-layer density gradient method was performed based on the new method and compared with the double-layer density gradient method to determine any statistical differences.Experimental conditions were strictly controlled for temperature,centrifugation speed,and duration,with the quantity and processing conditions of each sample recorded.[Results]Among the four double-layer density gradient methods,the sperm DNA fragmentation rate was lower with the 300×g 10 min treatment compared to 300×g 20 min while ensuring sufficient sperm recovery rates.Consequently,the 300×g 10 min method was selected as the new approach for experimentation.Results indicated that the total fertilization rate and 2 pronuclei(2PN)fertilization rate with the new 300×g 10 min method were higher than with the 300×g 20 min method,the difference was statistically significant(P<0.05).Although the cleavage rate with 300×g 10 min was slightly higher than 300×g 20 min,the difference was not statistically significant(P>0.05).The total fertilization rate and 2PN fertilization rate were slightly higher with the single-layer density gradient method compared to the double-layer density gradient method,but the difference was not statistically significant(P>0.05).The cleavage rate with the single-layer density gradient method was higher than the double-layer density gradient method,and the blastocyst formation rate is lower than that of the double-layer density gradient method,and the differences are statistically significant(P<0.05).[Conclusion]The 300×g 10 min double-layer density gradient method successfully improved total fertilization rates,2PN fertilization rates,and cleavage rates compared to the existing 300×g 20 min method,while reducing the time required for semen optimization processing.Although the single-layer density gradient method improves the cleavage rate,and saves reagent costs and operation time,its blastocyst formation rate has decreased.These findings provide valuable guidance and insights for semen processing methods in the field of reproductive andrology.
