ObjectiveTo compare the contents and relative molecular weight distributions of proteins and polypeptides in Naoxuekang dropping pills， Huoxue Tongmai capsules and Maixuekang capsules of Hirudo single medicinal preparations， to evaluate the in vitro anticoagulant， antiplatelet and fibrinolytic activities of the three preparations， and to investigate the effects of temperature， pH and digestive enzymes on the anticoagulant activities of the three preparations. MethodsThe contents of soluble proteins and polypeptides in the three preparations were determined by bicinchoninic acid assay（BCA） and Bradford method， and the relative molecular weight distributions of the three preparations were determined by electrophoresis combined with gel chromatography. The antithrombin activity of the three preparations was evaluated by fibrinogen-thrombin time（Fibg-TT） method， and their anticoagulant activities were further assessed by the elongations of activated partial thromboplastin time（APTT）， prothrombin time（PT） and thrombin time（TT）. The antiplatelet aggregation activities of the three preparations were measured by turbidimetry and the fibrinolytic activities were measured by fibrin plate method. Relative TT was used as index to investigate the effects of temperature， pH and digestive enzyme buffer on anticoagulant activities of the three preparations. ResultsAt the lowest single dosage， the contents of proteins and polypeptides were in the order of Maixuekang capsules>Huoxue Tongmai capsules>Naoxuekang dropping pills. Both Huoxue Tongmai capsules and Maixuekang capsules had 11 electrophoretic bands between 4.0 kDa and 90 kDa， the bands of Maixuekang capsules were more clear in the range of >25 kDa， and there was 1 obvious band at 14 kDa for the two capsules. Huoxue Tongmai capsules had one specific band at 9.0 kDa and Maixuekang capsules had one specific band at 48.0 kDa. Naoxuekang dropping pills only had 2 electrophoretic bands at 6.5 kDa and 8.5 kDa， primarily containing peptides below 2 kDa， most of which were oligopeptides. The anticoagulant activity concentrations of the three preparations exhibited a certain dose-dependent effect. At the lowest single dosage， The anticoagulant activity concentrations were ranked as Naoxuekang dropping pills>Huoxue Tongmai capsules>Maixuekang capsules. The prolongation effect of the three preparations on coagulation time was dose-dependent. At the same concentration， the prolongation effect of Naoxuekang dropping pills and Huoxue Tongmai capsules was APTT prolongation rate>TT prolongation rate>PT prolongation rate， whereas for Maixuekang capsules， the sequence was TT prolongation rate>APTT prolongation rate>PT lengthening rate. At the single minimum dosage， the order of APTT prolongation rate was Maixuekang capsules>Huoxue Tongmai capsules≈Naoxuekang dropping pills， the order of PT prolongation rate was Naoxuekang dropping pills≈Maixuekang capsules>Huoxue Tongmai capsules， and the order of TT prolongation rate was Maixuekang capsules>Huoxue Tongmai capsules>Naoxuekang dropping pills. The three preparations showed dose-dependent effects on platelet aggregation induced by adenosine diphosphate（ADP） and arachidonic acid（AA）， and the effect induced by ADP was stronger than that induced by AA. The anti-platelet aggregation effect of Naoxuekang dropping pills was significantly stronger than that of Maixuekang capsules（P<0.01）， whereas Huoxue Tongmai capsules had the effect of promoting platelet aggregation. None of the three preparations had the ability to dissolve fibrin. The anticoagulant activity of Naoxuekang dropping pills was least affected by heating， while the activities of the two capsules decreased significantly within 5 min above 80 ℃， and continued to decrease within 2 h. Compared with pure water， the anticoagulant activities of the three preparations could be increased by 1-3 times under strong acidity（pH 1-3）. In the pepsin buffer， the anticoagulant activity of Naoxuekang dropping pills could be increased by 1-3 times， while the anticoagulant activities of Huoxue Tongmai capsules and Maxuekang capsules were significantly decreased， the lowest levels were about 60% and 20%， respectively. In trypsin buffer， the anticoagulant activities of Naoxuekang dropping pills， Huoxue Tongmai capsules and Maixuekang capsules decreased significantly， and the lowest levels decreased to about 41%， 41% and 35%， respectively. ConclusionThe contents of proteins and polypeptides and relative molecular weights of the preparations derived from lyophilized fresh Hirudo powder， dried Hirudo powder and reflux extract of Hirudo decrease sequentially， and the anticoagulant activity decrease gradually， but the anticoagulant pathway is different. And the anti-platelet aggregation activity of the reflux extract is significantly enhanced. The heat resistance and gastrointestinal stability of the three preparations increase successively， and the first two are suitable for enteric-soluble preparations， while the latter is suitable for routine oral administration. The above results can provide data reference for the rationality of different preparation methods， active substances， pharmacodynamics and mechanism of Hirudo preparations.

ObjectiveTo observe the mechanism of Jiawei Guizhi Fuling decoction （JGFD） in alleviating sciatic nerve injury in painful diabetic peripheral neuropathy （PDPN） rats by regulating mitophagy through the PTEN-induced putative kinase 1 （PINK1）/Parkin signaling pathway. MethodThe PDPN model was established by intraperitoneal injection of streptozotocin （STZ）. After modeling， the rats were randomly divided into JGFD high， medium， and low dose groups （JGFD-H， JGFD-M， JGFD-L； 39.6， 19.8， 9.9 g·kg^-1·d^-1， respectively）， a positive drug group （lipoic acid capsules， LA； 50 mg·kg^-1·d^-1）， and a model group （PDPN）. A blank control group （CON） was established. Drug intervention was administered continuously for 8 weeks after modeling. Measurements included body weight and fasting blood glucose of PDPN rats at weeks 0， 2， 4， and 8， mechanical pain threshold and thermal pain threshold at weeks 0 and 8， and motor nerve conduction velocity at week 8. Hematoxylin-eosin （HE） staining was used to observe the morphology of sciatic nerve tissue. The ultrastructure of mitochondria and autophagosomes was observed by transmission electron microscopy. Western blot was performed to detect the protein expression levels of PINK1， Parkin， p62， Beclin-1， and LC3 in sciatic nerve tissue. Additionally， real-time quantitative PCR （Real-time PCR） was performed to detect the mRNA expression levels of PINK1， Parkin， p62， Beclin-1， and LC3 in sciatic nerve tissue. ResultCompared with the CON group， the PDPN group showed a significant decrease in body weight at all time points， a significant increase in fasting blood glucose， significantly shortened mechanical pain and thermal pain thresholds， and significantly reduced motor nerve conduction velocity. The protein and mRNA expression of PINK1， Parkin， Beclin-1， and microtubule-associated protein light chain 3（LC3） in sciatic nerve tissue was significantly reduced， while p62 protein and mRNA expression was significantly increased （P<0.01）. Pathological changes included edema of sciatic nerve fibers， segmental demyelination， loose and disordered arrangement of the myelin sheath layers， significant swelling of mitochondria， reduced electron density， disappearance of cristae， and absence of typical autophagosome and autolysosome structures. Compared with the PDPN group， each JGFD dose group showed a significant increase in body weight and a significant reduction in fasting blood glucose （P<0.05， P<0.01）. The mechanical pain threshold and thermal pain threshold were significantly prolonged， and motor nerve conduction velocity was significantly increased across all JGFD and LA groups. The expression levels of PINK1， Parkin， Beclin-1， and LC3 proteins and mRNA in sciatic nerve tissue were significantly increased， while p62 protein and mRNA expression levels were significantly decreased （P<0.05， P<0.01）. Pathological damage to the sciatic nerve was alleviated to varying degrees， with a relatively intact myelin sheath morphology and intact or slightly edematous outer mitochondrial membrane. Autophagolysosome structures were observed in the JGFD-M and JGFD-H groups. Compared with the LA group， the JGFD-H group showed a significant increase in body weight， a significant reduction in fasting blood glucose， a significant increase in motor nerve conduction velocity， a significant increase in PINK1 protein expression and PINK1， Parkin， and Beclin-1 mRNA expression in sciatic nerve tissue， and a significant decrease in p62 mRNA expression （P<0.05， P<0.01）. ConclusionJGFD may alleviate sciatic nerve injury in PDPN rats by activating mitophagy through the regulation of the PINK1/Parkin signaling pathway.

Objective·To explore the correlation between the genetic variations rs7305526 and rs11615756 of nitric oxide synthase 1(NOS1)and the human sleep traits,including insomnia,sleep duration,and clinical quantitative traits related to obstructive sleep apnea(OSA).Methods·The NOS1 gene expression pattern at the whole-brain level using the Allen Human Brain Atlas dataset was analyzed.Subsequently,we performed expression quantitative trait locus(eQTL)analysis to investigate the impact of rs7305526 and rs11615756 on NOS1 gene expression.Regression analysis was conducted to assess the associations between rs7305526 and rs11615756 with insomnia and sleep duration based on the United Kingdom Biobank(UKB)Genome-Wide Association Study(GWAS)dataset.Furthermore,we explored the relationships between rs7305526 and rs11615756 with clinical quantitative traits of OSA,such as respiratory events,oxygen levels,and sleep traits,using clinical monitoring data from the Shanghai Sleep Health Study Cohort(SSHS)based on standard polysomnography(PSG).Results·The NOS1 gene demonstrated elevated levels of expression in various brain regions crucial for regulating sleep,namely the amygdala,basal forebrain,striatum,and thalamus,as well as in the respiratory center,including the mesencephalon and pontine tegmentum.In contrast,the expression level of NOS1 gene was significantly reduced or absent in areas such as the cerebral cortex and cerebellum.Variants rs7305526 and rs11615756 were significantly negatively correlated with the expression levels of NOS1 in the cerebral cortex.Additionally,rs11615756 was also significantly negatively correlated with the expression level of NOS1 in the amygdala.Analysis of the UKB GWAS data revealed that the variant rs7305526 was not significantly associated with either insomnia or sleep duration,while rs11615756 demonstrated a noteworthy negative correlation specifically with sleep duration.Data obtained from the SSHS indicated a significant association between rs7305526 and alterations in clinical quantitative traits of OSA,including lowest pulse blood oxygen saturation(LSpO2),apnea-hypopnea index(AHI),and the ratio of non-rapid eye movement(NREM)stage 2 sleep duration.Although rs11615756 showed a notable negative correlation solely with the quantity of NREM stages 2 and 3,both rs11615756 and rs7305526 showed significant correlations with some respiratory events and oxygen traits after stratification according to the severity of OSA.Conclusion·Genetic variants of NOS1 gene are respectively associated with human sleep duration traits and OSA-related variables,suggesting that NOS1 gene plays a crucial regulatory role in human sleep and clinical quantitative traits of OSA.The regulation of sleep traits by rs7305526(C>A)is independent of its regulation of respiratory events and oxygen traits.

Objective:To investigate the diagnostic value of urine pH, serum uric acid and related clinical indicators in the diagnosis of urinary infection stones, and to construct a prediction nomogram.Methods:The clinical data of 432 patients with urinary calculi admitted to Xuzhou Central Hospital from August 2018 to November 2023 were retrospectively analyzed. The study included 289 males and 143 females, with an average age of (52.72±13.46) years old. Among the patients, there were 98 cases of hypertension, 67 cases of diabetes, and 100 cases of recurrent calculi. Kidney stones were present in 152 cases, ureteral stones in 242 cases, and bladder stones in 38 cases. Urine bacterial culture yielded positive results in 97 cases. According to the results of postoperative stone composition analysis, the two groups were categorized as infection and no-infection stone groups, and the differences in general data between the two groups were compared. Univariate and multivariate logistic regression analysis were conducted to assess the diagnostic value of urine pH, serum uric acid, and related clinical indicators for urinary infection stones. Receiver operating characteristic (ROC) curve and area under curve (AUC) were utilized to evaluate the clinical significance of urine pH, serum uric acid, and combined indexes in preoperatively diagnosing urinary infection stones, as well as constructing a nomogram prediction model.Results:There were 127 cases of infection stones and 305 cases of no-infection stones. The infection stone group exhibited a higher urine pH value [7.0(6.5, 7.5) vs. 6.0(5.5, 6.5), P<0.001], lower serum uric acid levels [(301.38±70.12) vs. (358.88±88.99) μmol/L, P<0.001], a higher proportion of females [55.1%(70/127) vs. 23.9%(73/305), P<0.001], younger age [(48.36±14.83)vs. (53.12±12.61)years old, P<0.001], a higher proportion of recurrence stones [34.6 %(44/127) vs. 18.4%(56/305), P<0.001], and a higher rate of positive urine bacteria culture[29.9%(38/127)vs. 19.3%(59/305), P=0.016]and nitrite test results [18.9%(24/127)vs. 6.3%(19/305), P <0.001]. Univariate logistic regression analysis revealed that urine pH value, serum uric acid levels, gender, age, recurrent stones, urine bacterial culture, and urine nitrite were associated with urinary infection stones ( P< 0.05). Multivariate logistic regression analysis revealed that urine pH value ( OR= 4.836, 95% CI 3.342-6.997), female gender( OR=2.320, 95% CI 1.286-4.186), recurrent stones ( OR=2.225, 95% CI 1.208-4.101), positive urine bacterial culture ( OR=2.061, 95% CI 1.094-3.883), serum uric acid ( OR=0.992, 95% CI 0.949-0.989), age ( OR=0.969, 95% CI 0.949-0.990) were independent risk factors for urinary infection stones ( P<0.05). The combined diagnostic value of six indicators was the highest, with an AUC of 0.874 (95% CI 0.837-0.911). Following this, urine pH exhibited an AUC of 0.818 (95% CI 0.778-0.858), while serum uric acid had an AUC of 0.704 (95% CI 0.652-0.756). The nomogram model was successfully constructed based on the six indicators. The mean AUC of the ROC curve after 1 000 resamples of the Bootstrap method was 0.864 (95% CI 0.828-0.900), and the calibration curve showed that the predicted curve fit the ideal curve well, with a mean absolute error of 0.005 and a Hosmer-Lemeshow test of P>0.05. Clinical decision curve analysis (DCA) showed that the model had a higher net clinical benefit when the model had a threshold probability value≥0.01. Conclusions:Urine pH and serum uric acid are closely related to urinary infection stones. A nomogram model combining these factors with gender, age, recurrent stones, and urine culture results can effectively predict the probability of infection-related stones, providing significant clinical value.

Objective:To compare the prognoses of salvage liver transplantation fulfilling the Criteria of Milan, University of California San Francisco(UCSF)and Hangzhou.Methods:Clinical data were retrospectively reviewed for 256 patients with recurrent hepatocellular carcinoma(HCC)undergoing donation after citizen death(DCD)liver transplantation(LT)from January 2015 to October 2019.They were divided into two groups of primary(PLT, n=175)and salvage(SLT, n=81). General profiles, tumor pathological characteristics and postoperative complications of two groups were compared by T-test, rank-sum or χ2 test.Kaplan-Meier method and Log rank test were employed for comparing overall survival rate(OS)and recurrence-free survival rate(RFS)between two groups.In SLT group, 31 cases fulfilled Milan criteria, 45 cases UCSF criteria and 69 cases Hangzhou criteria.OS/RFS of three groups were compared.According to there was downstaging or bridging treatment pre-LT, SLT group was divided into downstaging group(n=32)and non-downstaging group(n=49). OS/RFS of two groups were compared.According to the Rescit1.1 criteria, downstaging group were divided into remission group(n=14)and non-remission group(n=18)and OS/RFS of two groups were compared. Results:The operative durations of PLT and SLT groups were(439.5±74.9)and(475.1±83.4)min respectively.There was significant inter-group difference( P<0.05); However, no significant inter-group difference existed in amount of intraoperative bleeding, blood transfusion, postoperative hospital stay or incidence of postoperative complications(all P>0.05). No significant difference existed in OS/RFS between PLT and SLT groups( P>0.05). No significant difference existed in OS at 1/3/5 years post-SLT among Milan, UCSF and Hangzhou criteria groups(all P>0.05); However, RFS in Milan criteria group at 1/3/5 years post-SLT were 93.5%, 81.7% and 81.7% respectively.They were significantly higher than 68.9%, 59.7% and 59.7% in UCSF criteria group and 78.3%, 58.8% and 55.5% in Hangzhou criteria group(all P<0.05). For patients on downstaging therapy, OS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 73% and 73% respectively, which was significantly higher than 83.3%, 49.4% and 0 in non-Remission group( P=0.042). RFS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 62.5% and 46.9% respectively, which was significantly higher than 52.9%, 0 and 0 in no-Remission group( P=0.001). Conclusions:The survival outcome of SLT recipients is similar to that of PLT recipients.The overall survival of SLT recipients shows no significant difference between Milan, UCSF and Hangzhou criteria.However, SLT recipients fulfilling Milan criteria have the longest recurrence-free time.The prognosis of patients with remission after preoperative descending treatment is superior to that of patients without remission.

Objective:To investigate the imaging anatomical features of donor liver blood vessels in laparoscopic left lateral donor liver acquisition and their clinical significance.Methods:The retrospective and descriptive study was conducted. The clinical data of 39 living donor liver transplantation (LDLT) donors who were admitted to Huashan Hospital Affiliated to Fudan University between October 2016 and December 2018 were collected. There were 10 males and 29 females, aged (31±7)years. The clinical data of 39 LDLT recipients were collected. There were 26 males and 13 females, aged 8 months (range, 4-68 months). Abdominal enhanced computed tomography and three-dimensional vascular reconstruction were performed on donors to evaluate the anatomical characteristics of hepatic vessels. All the donors underwent laparoscopic left lateral donor liver acquisition. Observation indicators: (1) three-dimensional vascular reconstruction of preoperative imaging; (2) surgical conditions; (3) follow-up. Follow-up was performed using outpatient examination to detect complications of recipients after LDLT up to October 2019. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was analyzed by the t test. Measurement data with skewed distribution were represented as M (range). Count data were expressed as absolute numbers or percentages. Results:(1) Three-dimensional vascular reconstruction of preoperative imaging: the anatomical characteristics of hepatic artery and hepatic vein revealed by three-dimensional vascular reconstruction of preoperative imaging of 39 donors included ① middle hepatic artery was present in 11 donors, among which 5 started from the right hepatic artery, 3 from the confluence of the right and left hepatic artery, and 3 from the left hepatic artery. Two donors had anatomical variation in the left hepatic artery which was presentation of left accessory hepatic artery originated from the left gastric artery. The other 26 donors had no middle hepatic artery or anatomical variation in the left hepatic artery. ② The left hepatic vein and the middle hepatic vein of 9 donors were respectively drained into the inferior vena cava. Seven donors had the left upper branch of the left hepatic vein, and 23 donors had a joint trunk of the left hepatic vein and the middle hepatic vein which drained into the inferior vena cava. (2) Surgical conditions: ① all the 39 donors successfully underwent laparoscopic left lateral donor liver acquisition. The operation time and volume of intraoperative blood loss were (160±32)minutes and (142±74)mL. ② Of 11 donors with middle hepatic artery, left hepatic artery was the dominant artery in 8 donors and was used for hepatic artery anastomosis and reconstruction in liver transplantation, middle hepatic artery started from left hepatic artery in 3 donors and the joint trunk of left and middle hepatic artery was used for hepatic artery anastomosis and reconstruction in liver transplantation. Of 2 donors with anatomical variation in the left hepatic artery, one had left accessory hepatic artery as the dominant artery and the other had left hepatic artery as the dominant artery. Left accessory hepatic artery and left hepatic artery were respectively used for hepatic artery anastomosis and reconstruction in liver transplantation. The other 26 donors had left hepatic artery for hepatic artery anastomosis and reconstruction in liver transplantation. ③ Among the 39 donors, 11 received intraoperative left hepatic vein preferred approach and 28 received intraoperative non-left hepatic vein preferred approach. The operation time and volume of intraoperative blood loss of donors with left hepatic vein preferred approach were (147±22)minutes and (110±44)mL, respectively, versus (169±33)minutes and (154±81)mL of donors with non-left hepatic vein preferred approach, showing significant differences in the above indicators between the two groups ( t=4.19, 2.81, P<0.05). (3) Follow-up: 39 donors were followed up for 10 months. During the follow-up, there was no hepatic artery anastomotic bleeding, stenosis, ischemic bile duct injury and biliary stenosis caused by poor hepatic arterial blood supply, or any complications related to hepatic venous outflow tract stenosis. Conclusions:Three-dimensional vascular reconstruction before laparoscopic left lateral donor liver acquisition can reveal the anatomical variation of middle hepatic artery and left hepatic artery, which can guide the selection of surgical approach. The left hepatic vein preferred approach is recommended for the qualified donor in the laparoscopic left lateral donor liver acquisition, which can shorten the operation time and reduce the volume of intraoperative blood loss.

This study was aimed to observe the safety and effectiveness ofShugan Jieyu Capsules in the treatment of vasovagal syncope (VVS) with mild-to-moderate depression and anxiety, and to compare the effect with Flupentixol and Melitracen Tablets. A total of 89 VVS cases with mild-to-moderate depression and anxiety were randomly divided into 3 groups, which were group A (Shugan Jieyu Capsules group), group B (Flupentixol and Melitracen Tablets) and group C (control group). Based on the conventional therapy of VVS treatment, treatments were given to all three groups for 8 weeks. And the negative conversion ratio of VVS in each group was observed. Hamilton Depression Scale (HAMD 24 items) and Hamilton Anxiety Scale (HAMA) were evaluated for the calculation of reductive rate. Treatment emergent symptoms scale (TESS) was used in the evaluation of adverse reactions of both medications during the treatment. In the 12-month follow-up after treatment, the recurrence rate of syncope was observed in each group. The results showed that compared with pretreatment, HAMD-24 and HAMA scores of group A and group B after treatment were significantly reduced (P < 0.05). Compared with group C, the heat-up tilt testing-negative rate, HAMD-24 and HAMA reductive rate of group A and group B after treatment were significantly increased (P < 0.05). Compared with group B, the negative rate, HAMD-24 and HAMA reductive rate of group A were more significant (P < 0.05). After treatment, scores for TESS of group A was significantly lower than group B (P< 0.05). In the 24-month follow-up, the recurrence rate of syncope of group A and group B was significantly lower than group C (P < 0.05); and group A was obviously better than group B (P < 0.05). It was concluded thatShugan Jieyu Capsules can be used in the treatment of VVS with mild-to-moderate depression and anxiety. Its effectiveness and safety may be better than Flupentixol and Melitracen Tablets.

This study was aimed to investigate the effect ofDanlou pills on prevent atherosclerosis from hypercholesterolemia rabbit and its relationship with inflammatory factors as well as PI3K/AKT signal pathways. A total of 24 Japanese male white rabbits were randomly divided into the control group (CL), model group (M) and Danlou group (DL), with 8 in each group. Normal diet was given to CL rabbits. High-fat diet was given to rabbits in other groups to establish the atherosclerosis model. Danlou pills (0.5 g·kg-1·d-1) were also given to DL rabbits. Rabbits were sacrificed after 9-week medication. The contents of blood lipid, TNF-α and IL-6 were detected. HE staining was used in the observation of histological changes in the aorta. Western blot was used to observe PI3K and p-AKT expression in the aorta. The results showed that compared with CL, the contents of TG, TC, LDL, IL-6 and TNF-α were significantly increased in M (P < 0.01); PI3K and p-AKT expression in the aorta were significantly decreased (P < 0.01). Compared with M, blood lipid, IL-6 and TNF-α were significantly reduced in DL (P < 0.05, orP < 0.01); PI3K and p-AKT expression were significantly increased (P < 0.01). It was concluded thatDanlou pills had prevention effects on atherosclerosis through reducing blood lipid and inflammatory factors. The action mechanism maybe related to the activation of PI3K/AKT signal pathways.
