ABSTRACT
ObjectiveTo study the medication rules of Professor. WANG Xingkuan and inherit his academic experience in the treatment of chest stuffiness and pain with the aid of the Traditional Chinese Medicine Inheritance Computing Platform V3.0 （TCMICS V3.0）. MethodThe original medical records of patients with angina pectoris in coronary heart disease （CHD） diagnosed and treated by Prof. WANG in the outpatient department of Hunan University of Chinese Medicine from 2017 to 2020 were collected and entered into the TCMICS V3.0. The rules of prescriptions and drugs were analyzed by the software. ResultA total of 1 044 prescriptions of Prof. WANG for the treatment of chest stuffiness and pain were collected. Most of the drugs were sweet and bitter in flavor and mainly acted on the lung meridian， followed by heart， spleen， liver， stomach， and kidney meridians. Among the prescriptions， Shengmaisan was the most commonly used classic prescription， and Xintongling No. Ⅲ was the top experienced prescription. High-frequency drugs mainly included Ophiopogonis Radix， Pinelliae Rhizoma， Salviae Miltiorrhizae Radix et Rhizoma， Trichosanthis Pericarpium， Coptidis Rhizoma， Schisandrae Chinensis Fructus， and Bupleuri Radix. The common doses of drugs were 3， 5， 10， and 15 g. The analysis of formulation rules revealed 129 combinations of common drugs， 58 combinations with confidence > 0.99， and the core drugs of common syndromes. Six core drug combinations were obtained by drug clustering. ConclusionProfessor WANG treats chest stuffiness and pain based on syndrome differentiation following the principles of benefiting Qi， nourishing Yin， eliminating phlegm， resolving stasis， soothing liver， and promoting bile secretion， reflecting his academic idea of "regulation of multiple organs and comprehensive treatment". The core prescriptions can be used for reference by clinical practitioners， but further clinical and experimental studies are still needed to verify their efficacy.
ABSTRACT
Objective@#To monitor the adverse events following immunization (AEFI) with combined attenuated live measles, mumps and rubella vaccines (MMR) in Huzhou City from 2015 to 2021, so as to provide insights into the implementation of the MMR immunization strategy.@*Methods@#All AEFI caused by MMR immunization in Huzhou City from 2015 to 2021 were captured from the AEFI Monitoring Information Management System of the Immunization Planning System of Chinese Disease Control and Prevention Information System, and the incidence, clinical features and epidemiological features of AEFI were analyzed descriptively.@*Results@#The reported incidence of AEFI caused by MMR immunization appeared a tendency towards a rise in Huzhou City from 2015 to 2021 (χ2trend=124.126, P<0.001). Totally 324 386 doses of MMR vaccines were immunized, and 317 cases with AEFI were reported, with an reported incidence rate of 9.77/104 doses. Following two-dose immunization, the reported incidence of AEFI caused by two-dose MMR immunization was significantly lower than by one-dose immunization (6.01/104 doses vs. 25.43/104 doses; χ2=113.692, P<0.001). The incidence rates of general reactions, abnormal reactions and coincidental events were 6.20/104 doses, 3.42/104 dose and 0.15/104 doses, respectively. Fever and allergic rash were predominant clinical manifestations of AEFI, and no vaccine quality accident, inoculation accident or psychogenic reaction were reported. There were 246 (77.60%) cases with AEFI within 24 hours following vaccination, and among children with AEFI, there were 173 boys (54.57%), and 200 children (63.09%) age ages of less than one year (63.09%). AEFI was reported in each quarter, and 99 cases (31.23%) were reported in the fourth quarter. The largest number of children with AEFI was reported in Wuxing District (78 cases, 24.61%).@*Conclusions@#The safety of MMR vaccination is high in Huzhou City. General reaction is the predominant AEFI, which mainly occurs within 24 hours following vaccination. Two-dose MMR vaccination does not increase the risk of AEFI.
ABSTRACT
Objective:To observe the effects of "pushing patella and extending knee" manipulation on the protein and mRNA expression levels of integrin β1 (ITGβ1) and phosphorylated adhesion plaque kinase (p-FAK) in rabbit knee osteoarthritis (KOA) model, and to investigate the mechanism of manipulations in the treatment of KOA.Methods:Twenty healthy 6-month-old New Zealand rabbits were divided into the normal group, the model group, the acupuncture group, and the manipulation group according to the random number table method. Among them, the model group, the acupuncture group, and the manipulation group were modeled using the modified Hulth method for KOA. After 7 d of successful modeling, the normal group and the model group did not receive any intervention, while the acupuncture group and the manipulation group received one acupuncture intervention and one "pushing patella and extending knee" manipulation intervention daily, respectively. After 2 weeks of treatment, the rabbit KOA model was executed by air embolization, and the protein and mRNA expression levels of ITGβ1 and p-FAK in knee cartilage were measured by Western blot and real-time polymerase chain reaction (PCR), respectively.Results:Compared with the normal group, the ITGβ1 protein expression level was decreased ( P<0.05) and p-FAK protein expression level was increased ( P<0.05), and the mRNA expression levels of ITGβ1 and p-FAK did not change significantly (all P>0.05) in the model group. Compared with the model group, the ITGβ1 protein expression level was increased ( P<0.05), the p-FAK protein expression level decreased ( P<0.05), and the mRNA expression levels of both ITGβ1 and p-FAK increased (all P<0.05) in the acupuncture group. Compared with the acupuncture group, ITGβ1 protein expression level increased ( P<0.05), p-FAK protein expression level decreased ( P<0.05), and mRNA expression levels of both ITGβ1 and p-FAK increased (all P<0.01) in the manipulation group. Conclusions:The "pushing patella and extending knee" manipulation can optimize the protein and mRNA expression levels of ITGβ1 and p-FAK in the articular cartilage of the rabbit KOA model.
ABSTRACT
AIM: To investigate the efficacy and safety of 577nm subthreshold micropulse laser(SML)in patients with chronic central serous chorioretinopathy(CSC).METHODS: Prospective single-arm case study. There were 24 patients(32 eyes)with chronic CSC treated by using 577nm SML. A total of 6mo was followed up after treatment, the best corrected visual acuity(BCVA, LogMAR)and optic coherence tomography(OCT)were performed at each month. Fluorescein fundus angiography(FFA)was performed at 1,3 and 6mo after treatment.RESULTS: The BCVA was 0.46±0.34 and central retinal thickness(CRT)was 259.15±57.54μm of 32 eyes at baseline period. After treatment of SML at 1mo, there was no subretinal fluid in 21 eyes(66%), and subretinal fluid was observed in 11 eyes(34%). The BCVA was 0.43±0.27, the CRT was 232.13±42.58μm. CRT was significantly reduced compared to the baseline period(P<0.05). After treatment of SML at 3mo, subretinal fluid and fluorescein leakage from retinal pigment epithelium(RPE)were observed in 5 eyes(16%). The BCVA was 0.39±0.26 and CRT was 231.26±49.25μm. The CRT was still significantly lower than baseline period(P<0.05). The 5 eyes with subretinal fluid and leaked fluorescein were treated by using SML again. After treatment at 6mo, subretinal fluid was observed in only 3 eyes(9%). The BCVA was 0.19±0.47 and CRT was 217.25±35.54μm. Both of the BCVA and CRT showed a significant improvement from the baseline period(P<0.05). CONCLUSION:SML seems effective and safe for treatment of chronic CSC. It may be an alternative way for treatment of chronic CSC.
ABSTRACT
OBJECTIVE@#To investigate the correlation between the changes of cervical curvature and atlantoaxial instability.@*METHODS@#The correlation between the changes of cervical curvature and atlantoaxial instability was retrospectively studied in 50 outpatients with abnormal cervical curvature (abnormal cervical curvature group) from January 2018 to December 2019. There were 24 males and 26 females in abnormal cervical curvature group, aged from 18 to 42 years old with an average of(30.62±5.83) years. And 53 patients with normal cervical curvature (normal cervical curvature group) during the same period were matched, including 23 males and 30 females, aged from 21 to 44 years with an average of(31.98±6.11) years. Cervical spine X-ray films of 103 patients were taken in lateral position and open mouth position. Cervical curvature and variance of bilateral lateral atlanto-dental space(VBLADS) were measured and recorded, Pearson correlation coefficient analysis was used to study the correlation between the changes of cervical curvature and atlantoaxial instability.@*RESULTS@#Atlantoaxial joint instability accounted for 39.6%(21/53) in normal cervical curvature group and 84.0%(42/50) in abnormal cervical curvature group. There was significant difference between two groups(P<0.01). VBLADS in abnormal cervical curvature group was (1.79±1.01) mm, which was significantly higher than that in normal cervical curvature group(0.55±0.75) mm(P<0.01). Pearson correlation coefficient analysis showed that the size of cervical curvature was negatively correlated with VBLADS.@*CONCLUSION@#Cervical curvature straightening and inverse arch are the cause of atlantoaxial instability, the smaller the cervical curvature, the more serious the atlantoaxial instability.

ABSTRACT
Objective:To explore the clinical application and effect of repairing the donor site of ipsilateral fibular hallux flap with the transverse V-Y advancement flap of the great toe.Methods:Form January 2017 to January 2020, the donor sites of the ipsilateral fibular hallux flap were repaired by the transverse V-Y advancement flap of the great toe in the Department of Hand Surgery, 521 Hospital of Weapon Industry on 20 patients, including 16 males and 4 females with an average age of 33 (18-52) years old. First, the donor site of the fibular hallux flap was sutured to reduce the size of wound. The width of the remaining wound was 0.4 to 1.6 cm, and the area of the remaining wound was 0.5 cm×0.8 cm-1.6 cm×1.8 cm. Then the remaining wound was repaired with the transverse V-Y advancement flap of the ipsilateral great toe. The distance for transfer of transverse advancement V-Y flap was 0.2-0.8 cm, and the area of the transverse V-Y advancement flap was 1.0 cm×1.4 cm-1.8 cm×2.4 cm. The end of postoperative follow-up was scheduled in July 2021. The follow-up items included: survival of the transverse V-Y advancement flap, wound infection, appearance, shape, texture and sensation of the V-Y advancement flap, pain on the V-Y advancement flap and the great toe, cold tolerance and the scar condition at the donor site of the ipsilateral fibular hallux flap and the V-Y advancement flap, the appearance, sensation and flexion and extension of the great toe at the donor site, other discomforts in the donor site of great toe, walking and other functions affected by the discomforts.Results:The postoperative follow-up lasted from 12 to 18(average of 14) months. All the V-Y advancement flaps survived without infection at the donor sites of the great toe, and donor sites healed primarily. The appearance, shape and texture of the advancement V-Y flap were close to the skin of the same area of the contralateral great toe. The TPD of the V-Y advancement flap and the ipsilateral great toe ranged from 4 to 7 mm. The average score of the Visual analog scale(VAS) was 0.3 and 0.6 respectively in the evaluation of cold tolerance of the advancement V-Y flap and the ipsilateral great toe. The average score of the Vancouver scar scale(VSS) was 0.2 and 1.2 respectively in the scar evaluation of the V-Y advancement flap and the ipsilateral great toe. There was no visual difference between the appearance of the great toe at the donor site and the contralateral toe. There was no pain and other discomfort on the V-Y advancement flap and the ipsilateral great toe. The functions of the donor foot were not affected in walking, running, jumping and tiptoeing in all cases.Conclusion:It is a simple, safe and effective method to repair the donor site of the small-area ipsilateral fibular hallux flap by the transverse V-Y advancement flap of the great toe. It only causes a small wound but the appearance and function of the ipsilateral great toe can be repaired with a transverse V-Y advancement flap of the great toe.
ABSTRACT
To evaluate the clinical efficacy and safety of Hot AXIOS, a novel luminal metal stent with a cautery system guided by endoscopic ultrasound, for the treatment of infected pancreatic necrosis (IPN), 5 cases of IPN treated with endoscopic ultrasound-guided Hot AXIOS placement in Hangzhou First People's Hospital from December 2021 to January 2022 were retrospectively analyzed. The results showed that all 5 cases successfully completed the treatment, with 8-21 minutes of the operation time. The symptoms of abdominal pain and bloating on the first day after operation were significantly relieved, and the abdominal CT showed that the walled-off necrosis was significantly reduced. After 2-9 times of direct endoscopic necrosectomy, supplemented by antibiotics, patient's temperature and blood inflammatory indexes returned to normal, the cavity was reduced and necrosis was removed. The Hot AXIOS stent was indwelled for 12-40 days and then removed. After 25-113 days of the follow-up, all patients survived without recurrence. Preliminary results suggest that endoscopic ultrasound-guided Hot AXIOS placement is safe and effective for the treatment of IPN.
ABSTRACT
Objective:To investigate the effect of CIRc_0000267 on proliferation, migration, invasion and apoptosis of gastric cancer cells in vitro.Methods:Gastric cancer cell lines with circ_0000267 knockdown and miR-661 overexpression were constructed in vitro, and the expressions of circ_0000267, miR-661 and NGAL mRNA in gastric cancer tissues and cells were detected by qRT-PCR. Cell proliferation, migration, invasion and apoptosis were detected by clonogenesis, Transwell chamber and flow cytometry, and related protein expression was detected by Western blot. Online prediction combined with double luciferase assay and RNA pull down assay was used to verify the targeting relationship between circ_0000267, miR-661 and NGAL. Tumogenesis assay in nude mice was used to observe the effect of circ_0000267 knockout on the growth of gastric cancer cells in vivo. Results:Circ_0000267 was highly expressed in gastric cancer tissues and cells. Knockdown circ_0000267 inhibited the proliferation, migration and invasion of gastric cancer cells and promote apoptosis. Circ_0000267 targeted miR-661, and inhibition of miR-661 partially reversed the effect of circ_0000267 on gastric cancer cells. NGAL was the target gene of miR-661, and overexpression of miR-661 regulated the proliferation, migration, invasion and apoptosis of gastric cancer cells by inhibiting NGAL. Knockdown circ_0000267 targeting miR-661 inhibited NGAL expression in gastric cancer cells; Knockdown circ_0000267 inhibited the growth of gastric cancer cells in vivo.Conclusions:Circ_0000267 may regulate the proliferation, migration, invasion and apoptosis of gastric cancer cells and inhibit the growth of tumors in vivo by regulating the expression of miR-661/NGAL.
ABSTRACT
Objective:This study aims to reveal the special immune infiltrating environment and possible immune escape mechanism of giant cell tumor of bone through single-cell sequencing data.Methods:The fresh samples obtained from 4 patients with primary giant cell tumor of bone from January 2018 to December 2021 were collected, and single-cell transcriptome sequencing was performed on the 10X platform to explore the characteristics and immune environment of giant cell tumor of bone by using t-distributed stochastic neighbor embedding ( t-SNE). The main cell types and signal pathways of immune cell regulation and function in giant cell tumor of bone were observed by cell communication analysis. Results:Cell clustering, the definition of basic cell types, the classification of immune cells, and the mutual regulatory relationship between cell types were analyzed for 35 643 single-cell data from 4 giant cell tumor samples of bone. It was found that giant cell tumor of bone was composed of 9 basic cell types, in which the immune cells were mainly CD8 + T cells (51%) and the non-immune cells were mainly fibroblast like spindle stromal cells (74%). The immune infiltration of giant cell tumor of bone is dominated by cytotoxic CD8 + T cells and lacks exhausted CD8 + T cells. CD4 + T cells are characterized by high expression of immune checkpoint genes CTLA4 and TIGIT. In giant cell tumor of bone, immune cells mainly act on multinucleated osteoclast like giant cells through PARs and CCL signaling pathways, but not stromal cells. Conclusion:This study defined the main cell types of giant cell tumor of bone through single cell sequencing data, and further revealed the composition characteristics of its immune infiltration, and found that the target of its immune cells was mainly multinuclear osteoclast like giant cells, which provided effective information for further understanding the occurrence and development of giant cell tumor of bone.
ABSTRACT
Objective:To analyze the efficacy and prognosis of different surgical treatments for Bismuth-Corlette type III and IV hilar cholangiocarcinoma (HCCA).Methods:The clinical data of 86 Bismuth-Corlette type III and IV HCCA patients treated at the First Affiliated Hospital of Anhui Medical University from January 2010 to December 2016 were retrospectively analyzed. There were 45 males and 41 females with age of (59.5±10.5) years old. According to the operative method, 57 patients were included into the extended hepatectomy group, and 29 patients into the perihilar hepatectomy group. The perioperative clinical data and survival rates were compared between the two groups. Through inpatient interviews, regular outpatient or telephone follow-up, factors affecting prognosis were analyzed by univariate and multifactorial Cox regression.Results:The operative time and intraoperative blood loss in the extended hepatectomy group were significantly higher than those in the perihilar hepatectomy group, [320(270, 380) min vs. 270(210, 300) min, P<0.001; 300(200, 400) ml vs. 100(100, 150) ml, respectively P<0.001]. The incidences of ≥ Clavien-Dindo grade III complications and ISGLS grade C liver failure in the extended hepatectomy group were significantly higher than those in the perihilar hepatectomy group [36.4%(20/57) vs. 13.8% (4/29), P=0.037; 13.8% (7/57) vs. 0(0/29), respectively P=0.047]. The cumulative 1-, 3- and 5-year survival rates of the extended hepatectomy group were 89.5%, 38.6% and 19.3%, respectively. The cumulative 1-, 3- and 5-year survival rates of perihilar hepatectomy group were 86.2%, 20.7% and 10.3%, respectively. The difference between the two groups was statistically significant ( P=0.048). Multivariate analysis showed that perihilar hepatectomy ( HR=1.958, 95% CI: 1.174-3.268, P=0.010), non-R 0 resection ( HR=6.040, 95% CI: 2.915-12.513, P<0.001) and TNM stage III/IV( HR=2.144, 95% CI: 1.257-3.654, P=0.005) were independent risk factors for overall survival after surgery for HCCA patients ( P<0.01). Conclusions:Patients with Bismuth-Corlette type III and IV HCCA who received extended hepatectomy had significantly better overall survival than those patients who underwent perihilar hepatectomy. However, the incidences of surgical complications and liver failure in the extended hepatectomy group were also significantly higher.

ABSTRACT
Objective:To explore the value of high resolution vascular wall MRI (VW-MRI) in drug balloon therapy of intracranial atherosclerotic stenosis.Methods:A total of 21 patients with intracranial atherosclerotic stenosis admitted to the First Affiliated Hospital of Shandong First Medical University from September 2019 to July 2021 were retrospectively analyzed, aged 22-73 (49±15) years, including 15 males and 6 females. All patients were treated with SeQuent Please drug coated balloon recanalization, and performed digital subtraction angiography (DSA), routine MRI and VW-MRI examinations within one week before operation and 2 to 3 months after treatment. The changes of atherosclerotic plaque area, length, enhancement index and stenosis degree before and after recanalization were evaluated. Paired t-test or Wilcoxon test was separately used to compare the difference before and after operation. The value of plaque characteristics in evaluating postoperative efficacy was analyzed by the receiver operating characteristic (ROC) curve. Pearson correlation analysis and Bland-Altman images method were used to test the correlation and consistency of VW-MRI and DSA in measuring the lumen stenosis degree. Results:After endovascular treatment with drug-coated balloon, the plaque area [(1.86±1.28)mm 2], length [3(2, 4)mm],enhancement index [(60±20)%] and lumen stenosis degree [(28±16)%] were significantly lower than those before endovascular treatment [(5.97±1.15)mm 2, t=10.93, P<0.001; 7(6, 9)mm, Z=-3.94, P<0.001; (107±46)%, t=4.26, P<0.001; (89±5)%, t=17.27, P<0.001]. The plaque area, length and enhancement index showed diagnostic value for evaluating the endovascular treatment efficacy (area under the ROC curve=0.89, 0.86, 0.74, respectively). Stenosis degree measured by VW-MRI had a positive correlation ( rpreoperative=0.66, P<0.001; rpostoperative=0.96, P<0.001) and consistency with DSA before and after recanalization. Conclusion:VW-MRI can be used to comprehensively and effectively evaluate treatment effect after endovascular treatment from the changes of plaque basic characteristics and stenosis degree, which is a good imaging follow-up tool.

ABSTRACT
Objective:To investigate the feasibility and safety of a novel single-port robotic surgical system with flexible 3D endoscope and deformable surgical instruments in zero ischemic partial nephrectomy.Methods:From May 2021 to October 2021, a prospective study on patients with renal tumor who plan to receive zero ischemic partial nephrectomy was conducted. Inclusion criteria included over 18 years old, body index between 18.5 to 30.0 kg/m2, American Society of Anesthesiologists Score ranged from 1 to 3 points, cooperation with the follow-up and related examinations, voluntary in participating the clinical trial and signing the informed consent. Exclusion criteria included patients with other co-existed malignant tumors or a medical history of other malignant tumors, the patients who have received the same urological surgery in the past, the patients who underwent or plan to undergo other major operations 3 months before or after the surgery, the patients with active pulmonary tuberculosis or severe systemic diseases, the patients to be considered not suitable to enroll in by the researchers. A novel single-port robotic surgical system was used to perform the surgery. The system consiststed of a remote control console, a surgical equipment cart, a four-arm operation cart and deformable robotic instruments which were reusable. The two-section deformable robotic instruments were able to bend in four directions and carried different surgical instruments such as unipolar scissors, bipolar grasping forceps and needle holders. The deformable robotic instruments entered the body through a special trocar with single hole and multi-channel, and then unfolded in a triangle. By bending instruments, surgeons could perform single-port robotic surgery without the trouble of "chopstick effect" or "reverse direction" . Four cases of single-port partial nephrectomy were carried out. Under general anesthesia, the patients were taken the lateral recumbent position, with elevated waist and lowered head and feet. A 3-4 cm incision was taken layer by layer along the lateral edge of the rectus abdominis at the umbilicus level. A special 2.5 cm robotic trocar was set into the cavity, and a high-definition 3D laparoscopic lens and a snake shaped mechanical arm were then put into the abdominal cavity through the trocar. All operations were performed by transperitoneal approach with an auxiliary port through the same or a different skin incision if necessary. Tumor resection and renal reconstruction were performed by the way of zero ischemia. The perioperative parameters such as tumor size, operation time, intraoperative bleeding and postoperative complications were analyzed.Results:Four patients were involved, including 2 males and 2 females, with 2 of them having a history of hypertension. The ECOG scores were all 0, and KPS score was 100 in 3 cases and 90 in 1 case. Preoperative mean serum creatinine was (76.8±18.8)μmol/L (range 70-104 μmol/L). The tumors were located on the left in 3 cases and on the right in 1 case. The diameter of the tumor ranged from 1.1 to 2.8 cm, with the TNM classification of T 1a. The R. E.N.A.L. scores were 4a, 7p, 6p and 4P respectively. The first operation was performed by pure single-port surgery, and the other 3 cases were performed with the help of an auxiliary port to ensure the safety .The operation time ranged from 155 min to 210 min, and the intraoperative bleeding ranged from 20 ml to 170 ml. Postoperative pathology showed 2 cases of renal clear cell carcinoma with negative margin and 2 cases of angiomyolipoma. No severe complications, such as bleeding or urinary leakage, were observed during the perioperative period, and the change of serum creatinine was insignificant before discharge and before operation( P=0.24). Conclusions:A robotic single-port partial nephrectomy can be successfully carried out by using this novel single-port robotic surgical system with flexible 3D endoscope and deformable surgical instruments.
ABSTRACT
Objective:To explore the application value of three-dimensional visualization technology in the analysis of anatomic variation of peripancreatic vessels in patients with pancreatic space occupation.Methods:A total of 98 cases in Yijishan Hospital of Wannan Medical College, the First Affiliated Hospital of University of Science and Technology of China, the First Affiliated Hospital of Anhui Medical University, the Second Affiliated Hospital of Anhui Medical University, the First Affiliated Hospital of Bengbu Medical College, Fuyang People's Hospital from June 2018 to December 2019 were retrospectively analyzed. Of 94 patients were enrolled, including 56 males and 38 females, aged (61.2±7.2) years. Abdominal organs and blood vessels were reconstructed by 3D visualization technology, and anatomic variation of peripancreatic vessels was analyzed, including abdominal trunk, hepatic artery system, portal vein system and dorsal pancreatic artery.Results:The three-dimensional reconstruction rate of celiac trunk vessels was 100.0% (94/94). The 60 cases of abnormal celiac trunk were as follows: liver and spleen trunk in 5 cases (5.3%), stomach and spleen trunk in 1 case (1.1%), liver, stomach and spleen mesentery trunk in 3 cases (3.2%), liver, stomach and spleen mesentery trunk in 17 cases (18.1%), celiac trunk with one or more inferior phrenic arteries in 34 cases (36.2%). There were 69 cases (73.4%) of Michels type Ⅰ, 2 cases (2.1%) of Michels type Ⅲ, 1 case (1.1%) of Michels Ⅴ, 2 cases (2.1%) of Ⅷ, and 1 case (1.1%) of type Ⅸ of hepatic artery system. There were 17 cases (18.1%) of accessory left hepatic artery from celiac trunk which did not belong to Michels classification. Left accessory hepatic artery originated from left gastric artery and left hepatic artery originated from superior mesenteric artery in 1 case (1.1%), right accessory hepatic artery originated from celiac trunk combined with proper hepatic artery and right anterior hepatic artery combined with gastroduodenal artery originated from right posterior hepatic artery in 1 case (1.1%). Abnormal walking of dorsal pancreatic artery in 3 cases. The inferior mesenteric vein flowed into the superior mesenteric vein in 38 cases (40.4%), and the inferior mesenteric vein flowed into the splenic vein and superior mesenteric vein in 4 cases (4.3%).Conclusion:Three-dimensional visualization technique is helpful to determine the variation of peripancreatic vessels, and has certain significance for accurate preoperative evaluation and surgical guidance of patients with pancreatic space occupation.
ABSTRACT
The important pathogenesis of knee osteoarthritis (KOA) lies in kidney deficiency and blood stasis. Therefore, Traditional Chinese Medicine (TCM) for tonifying the kidney and activating blood circulation is widely used in clinical practise with high response. The existing literature mainly focuses on single medicine for tonifying the kidney and activating blood circulation, as well as TCM compounds, such as classic prescriptions Yougui Pill, Duhuo Jisheng Decoction, which contain TCMs for tonifying the kidney and activating blood circulation, or self-made empirical prescriptions Bushen Huoxue Recipe and Bushen Tongluo Recipe, which are based on the idea of tonifying the kidney and activating blood circulation. The above TCMs mainly regulate oxidative stress response, inflammatory cytokine level, no level, lymphatic function and microcirculation Inhibit chondrocyte apoptosis, regulate cartilage metabolism, protect and repair cartilage, and inhibit matrix degrading enzymes to play a therapeutic role.
ABSTRACT
Although multifarious tumor-targeting modifications of nanoparticulate systems have been attempted in joint efforts by our predecessors, it remains challenging for nanomedicine to traverse physiological barriers involving blood vessels, tissues, and cell barriers to thereafter demonstrate excellent antitumor effects. To further overcome these inherent obstacles, we designed and prepared mycoplasma membrane (MM)-fused liposomes (LPs) with the goal of employing circulating neutrophils with the advantage of inflammatory cytokine-guided autonomous tumor localization to transport nanoparticles. We also utilized in vivo neutrophil activation induced by the liposomal form of the immune activator resiquimod (LPs-R848). Fused LPs preparations retained mycoplasma pathogen characteristics and achieved rapid recognition and endocytosis by activated neutrophils stimulated by LPs-R848. The enhanced neutrophil infiltration in homing of the inflammatory tumor microenvironment allowed more nanoparticles to be delivered into solid tumors. Facilitated by the formation of neutrophil extracellular traps (NETs), podophyllotoxin (POD)-loaded MM-fused LPs (MM-LPs-POD) were concomitantly released from neutrophils and subsequently engulfed by tumor cells during inflammation. MM-LPs-POD displayed superior suppression efficacy of tumor growth and lung metastasis in a 4T1 breast tumor model. Overall, such a strategy of pathogen-mimicking nanoparticles hijacking neutrophils in situ combined with enhanced neutrophil infiltration indeed elevates the potential of chemotherapeutics for tumor targeting therapy.
