[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

Apoptosis inhibitor of macrophage(AIM)belongs to group B of the scavenger receptor cysteine rich-super family.AIM is a soluble protein secreted by macrophages.The expression of this protein is controlled by the liver X receptor.AIM,which is secreted by macrophages,plays important and broad roles in the immune responses of the body.It not only inhibits the apoptosis of macrophages but also participates in the regulation of macrophage polarization.In addition,studies have revealed that AIM is involved in various physiological and pathological processes,such as inflammation,obesity,atherosclerosis,and cancer.It has been used as a biological marker for the diagnosis of diseases such as tuberculosis and liver cirrhosis.Moreover,it can promote the lipolysis of adipose cells by inhibiting the activity of fatty acid synthase(FAS),playing an important role in the regulation of lipid homeostasis,lipid metabolism,and autoimmune diseases.In this paper,we review the multiple functional characteristics of AIM and its effects on inflammation,lipid metabolism,and related diseases to provide a theoretical basis for relevant medical research.

ObjectiveBased on network pharmacology and transcriptomics， the mechanism of Zishen Qinggan prescription （ZSQGF） in improving glucose and lipid metabolism in type 2 diabetes （T2DM） model rats was explored. MethodBased on network pharmacology analysis of the differential genes between ZSQGF and T2DM， gene ontology（GO）analysis and Kyoto encyclopedia of genes and genomes（KEGG） analysis were conducted， and molecular docking analysis was used to verify the binding between components and targets. A T2DM rat model was established by high-fat feeding and injection of streptozotocin （STZ）. The rats were randomly divided into the control group， model group， metformin （Met， 72 mg·kg^-1） group， and ZSQGF high-， medium-， and low-dose groups （ZSQGF-H， ZSQGF-M， and ZSQGF-L， with 4.8， 2.4， and 1.2 g·kg^-1 raw drug in the solution）. The living status of rats was monitored and the levels of total cholesterol （TC）， total triglycerides （TG）， high density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， aspartate aminotransferase （AST）， and alanine aminotransferase （ALT） in rat serum were detected. The liver tissues were subjected to Hematoxylin eosin（HE） staining and oil red O staining. The differential genes were analyzed through transcriptomics， GO and KEGG analysis， and the protein-protein interaction（PPI） network was obtained to screen key targets. With network pharmacology and transcriptomics analysis results， the protein pathways were identified. The expression levels of nuclear factor-κB （NF-κB）， matrix metalloproteinase（MMP）-1 and MMP-9 proteins in liver tissues were detected by Western blot. The mRNA expression of B-cell lymphoma-2（Bcl-2） modifying factor（BMF）， nicotinamide adenine dinucleotide phosphate （NADPH） oxidase 4 （NOX4）， and fatty acid synthase（FASN） was detected by real-time polymerase chain reaction（Real-time PCR）. The expression of MMP-1 and MMP-9 in the liver was detected by immunofluorescence staining. ResultTranscriptomics and network pharmacology analysis suggested that ZSQGF may protect the liver through the glucose and lipid metabolism pathway and the inflammation pathway. Experiments showed that after 8 weeks of administration， the body weight， blood sugar， serum indicators， and pathological staining results of rats were improved. Western blot results indicated a decrease in the relative expression levels of NF-κB， MMP-1 and MMP-9 proteins in the liver. Real-time PCR results showed a decrease in the transcriptional expression of BMF， NOX4， and FASN in the ZSQGF-H group， while immunofluorescence staining results present decreased expression of MMP-1 and MMP-9 in the ZSQGF groups. ConclusionZSQGF can improve the glucose and lipid metabolism by inhibiting the expression of FASN， reducing lipid synthesis， and regulating the NF-κB signaling pathway.

Objective:To explore the regulatory effect of Suaeda salsa on renal apoprosis inhibitor of macrophage (AIM) and macrophage polarization in diabetes kidney disease (DKD) model rats.Methods:A DKD rat model was established using a high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin (STZ). The rats were divided into model group, metformin group, and Suaeda salsa high-, medium-, and low-dosage groups using a random number table method, with 8 mice in each group. The normal group was set with 8 rats in this group. The metformin group was given 85.71 mg/kg of metformin solution by gavage, while the Suaeda salsa high-, medium-, and low-dosage groups were given 3.08, 1.54, and 0.77 g/kg of Suaeda salsa suspension by gavage (raw dosage). The normal group and model group were given equal volumes of saline by gavage, once a day, administered by gavage for 12 weeks of intervention. Fasting blood glucose (FBG) and glucose tolerance (OGTT) were measured, and the area under the curve (AUC) was calculated; the levels of glycosylated hemoglobin (HbA1c) and glycosylated serum protein (GSP) were detected; urea nitrogen (BUN), serum creatinine (SCr), and 24-hour urine protein (24 hUP) were detected; HE staining was used to observe the pathological morphology of the kidneys; Masson and PAS staining were used to observe renal tissue fibrosis; Western blot method was used for detecting AIM, CD206, CD86, TNF-α and IL-10 protein levels in renal tissue; Immunofluorescence was used to detect the average optical density values of AIM, CD206, and CD86 proteins in renal tissue.Results:Compared with the model group, the FBG, OGTT AUC, HbA1c, GSP of each dosage group of Suaeda salsa decreased ( P<0.01); the expression levels of AIM, CD206, and IL-10 proteins in renal tissue increased ( P<0.01 or P<0.05), while the expression levels of CD86 and TNF-α protein significantly decreased ( P<0.01 or P<0.05); HE, Masson, and PAS staining results showed that compared with the model group, the changes in renal microvasculature and renal fibrosis of rats in each dosage group of Suaeda salsa were improved. Conclusion:Suaeda salsa may regulate AIM, promote polarization of M2 macrophages, improve the inflammatory microenvironment of macrophages, thereby lowering blood lipids of DKD rats, and improving renal pathological damage.

The functional reconstruction of large maxillofacial defects is a major issue in oral and maxillofacial surgery, and autologous bone transplantation is the main method. However, bone is readily absorbed following an autologous bone transplant. Even with vascular anastomosis, spontaneous osteoporosis of transplanted bone is still serious, which affects dental implantation and functional recovery. Therefore, osteoporosis of the grafted bone has become one of the main complications of jaw reconstruction, and there is no preventive measure. The problem that autologous bone with sufficient blood supply cannot avoid osteoporosis suggests that systemic factors such as nerves, which have been neglected in traditional methods, may regulate the internal environment of the transplanted bone. Based on previous studies on the regulation of mesenchymal stem cells by the neural microenvironment, we initiated a new surgical procedure for innervated and vascularized iliac bone flaps based on animal model and cadaver studies. In the innervated and vascularized iliac bone flap, vascular microanastomosis was performed in conjunction with microneuronal anastomosis between the simultaneously harvested ilioinguinal nerve (which innervates the iliac bone and is usually sacrificed and neglected in the conventional vascularized iliac bone flap) and the inferior alveolar nerve proximally and with the mental nerve distally. By conducting clinical retrospective studies and prospective randomized controlled trials, we proved that the novel method of simultaneous innervated iliac bone transplantation can not only prevent bone resorption but also restore the sensation of adjacent soft tissues such as the lip. This may solve the key problems of sensory loss and osteoporosis after mandibular reconstruction, ensure the success of dental implant dentures, and put forward the new concept of "blood supply + innervation" bi-system bone transplantation.

Objective:To explore the clinical effect of the simultaneous innervated "Bi-system bone flap" on preventing postoperative spontaneous resorption of the bone grafts and recovering lip sensation after reconstructing mandibular defects.Methods:Patients with segmental mandibular defects from the Department of Oral and Maxillofacial Head and Neck Oncology, Shanghai Ninth People’s Hospital were prospectively selected. Following the screening, they were randomly divided into an innervated group and a control group according to the random number table. When the free vascularized iliac bone flap was used to repair the mandibular defect, the ilioinguinal nerve was chosen to innervate a composite tissue flap containing one pedicle (deep circumflex iliac artery), double islands (an internal oblique muscle flap and an iliac bone flap) and one nerve (ilioinguinal nerve). We anastomosed the ilioinguinal nerve with the inferior alveolar nerve and the mental nerve in the innervated group. In the control group, no nerve was involved in the composite tissue flap which contained one pedicle (deep circumflex iliac artery) and double islands (internal oblique muscle flap and iliac bone flap). CT value(Hu) decrease rate, width and height of iliac bone flap 6 months after the operation were used to evaluate the postoperative resorption. The algesia examination, two-point discrimination test and current perception threshold (CPT) test of sensory nerves were used to evaluate the recovery of the lower lip sensation. P value less than 0.05 in independent-samples t test meant the statistically significant difference. Results:Eight patients between 17-38 years old were included with an averaged age of 29.5 years, and the range of mandibular defects was 5-9 cm. There were 4 cases in the innervated group and 4 cases in the control group. All the iliac bone flaps survived. The appearance was satisfactory, and no severe complications were found in the donor and recipient sites. In six-month follow-up, the CT value decrease rate of the bone grafts was (3.13±1.21)% in the innervated group, less than that (20.32±5.23)% in the control group, and the difference was statistically significant ( t=-6.401, P=0.006). Few changes of width and height of the bone grafts were found 6 months after surgery in both groups, and the difference was not statistically significant ( P>0.05). The sensation of the lower lip in the operation area was recovered in the innervated group to some extent, and no obvious pain was showed in the control group. In the two-point discrimination test, it was more than 20 mm in the affected side of the control group, while it was less than 20mm in the innervated group. In the healthy side of the two groups, it was less than 14 mm. The results of the quantitative sensory examination in affected lower lip by CPT test showed that two cases in the innervated group were mild sensory dysfunction, one slight sensory dysfunction and one moderate sensory dysfunction, while all cases in the innervated group were severe sensory dysfunction. The sensory dysfunction of the healthy side was milder than that of the affected side. Conclusions:The innervated "Bi-system" DCIA flap can prevent postoperative osteoporosis of the bone grafts and recover the sensation of the lower lip following mandibular reconstruction, improving the quality of mandibular defect reconstruction.
