This paper summarizes Professor LU Fang's clinical experience in treating systemic lupus erythematosus （SLE） based on the differentiation and treatment of heat-toxin and blood-stasis in the collaterals. SLE is generally characterized by deficiency in origin with excess in manifestation. The core pathogenesis is heat-toxin obstructing the collaterals. During the acute active stage， the predominant pattern is blazing heat-toxin causing blood stasis， while in the chronic remitting stage， the main pattern is toxic stasis blocking the collaterals with qi and yin deficiency. Clinical treatment follows the basic principle that treat with salty-cold herbs， when heat invades internally and that assist with acrid-dispersing herbs when stasis obstructs the collaterals. The self-formulated Yimian Decoction （抑免汤） serves as the base formula and is applied in stages. During the acute active stage， it is often combined with herbs for clearing heat and detoxifying， cooling blood and resolving stasis， and unblocking the collaterals. In the chronic remitting stage， it is often combined with herbs for activating blood circulation and unblocking the collaterals， as well as tonifying qi and nourishing yin.

Anorectal malignant melanoma is a rare and highly aggressive malignant tumor,often misdiagnosed as benign conditions such as rectal polyps or thrombosed hemorrhoids.In this case,the patient underwent 3D laparoscopic abdominoperineal resection for rectal cancer at our hospital on April 16,2024,with pathological examination confirming malignant melanoma.As of August 9,2024,contrast-enhanced computed tomography of the chest and abdomen and magnetic resonance imaging of the whole abdomen suggested multiple systemic metastases.This underscores that patients with malignant melanoma are often at an advanced stage at the time of clinical presentation.Current treatment primarily involves surgery combined with various adjuvant therapies;however,the prognosis remains poor.The cornerstone of management lies in early recognition and timely intervention.

OBJECTIVE: To develop a polymerase chain reaction-sequence specific primer (PCR-SSP) method for simultaneous amplification and identification of the KIR genes among Chinese population. METHODS: Peripheral blood samples from 132 healthy donors who had given blood at Shenzhen Blood Center from January 2015 to November 2015 were selected as the study subjects. Based on the polymorphism and single nucleotide polymorphism (SNP) information of high-resolution KIR alleles in the Chinese population and the IPD-KIR database, specific primers were designed to amplify all the 16 KIR genes and the 2DS4-Normal and 2DS4-Deleted subtypes. The specificity of each pair of PCR primers was verified by using samples with known KIR genotypes. During PCR amplification of the KIR gene, co-amplification the fragment of human growth hormone (HGH) gene by multiplex PCR was used as the internal control to prevent false negative results. A total of 132 samples with known KIR genotypes were randomly selected for blind inspection to verify the reliability of the developed method. RESULTS: The designed primers can specifically amplify the corresponding KIR genes, with clear and bright bands for the internal control and KIR genes. The results of detection are fully consistent with the known results. CONCLUSION The KIR PCR-SSP method established in this study can yield accurate results for the identification of the presence of KIR genes.

A 4-year-old boy received an IV infusion of cefoperazone sodium sulbactam sodium 0.8 g once per 12 hours for severe pneumonia. On day 3 of the treatment, the child developed brown urine, abdominal pain, pale skin, and cold limbs at about 15 minutes of the infusion. Then the infusion was stopped immediately. Laboratory tests showed decreased red blood cell count 1.7×10 12/L(4.7×10 12 before treatment) and hemoglobin 67 g/L(121 g/L before treatment), reticulocyte 0.12, total bilirubin 54.7 μmol/L, indirect bilirubin 42.4 μmol/L, direct Coombs test positive, urine protein (++), urine occult blood (++), urobilinogen (+++), 87 urine red blood cells per high power field. The acute hemolysis caused by cefoperazone sodium sulbactam sodium was considered. The drug was discontinued immediately and IV infusion of methylprednisolone and other symptomatic treatments were given. Then the boy′s condition gradually improved. The anti infection treatment was replaced by azithromycin for injection. On day 9 of cefoperazone sodium sulbactam sodium withdrawal, the boy′s blood routine and urine routine returned to normal and the direct Coombs test was negative.

Objective: To explore the long-term effect of neuroendoscopy followed by radiotherapy on cystic craniopharyngiomas. Methods: Cystic craniopharyngiomas in 9 patients were treated with neuroendoscopic cyst aspiration and fenestration, followed by fractionated stereotactic radiotherapy (FSRT). The neuroendoscopic procedure focused on widening of cyst fenestration and extensive irrigation of the cyst contents. The collimator of FSRT ranged from 2.5 cm to 3.0 cm, and the target volume 1.1-43.8 cm^3, dose per fraction 1.8 Gy, total dose 50.4 Gy. Results: The median follow-up period was 72.9 months. Tumor control was achieved in 8 of 9 patients. Marked tumor volume reduction was obtained with the neuroendoscopic procedure alone at 6 months, 1 year, and 2 years. One recurrent case showed multilobulated cysts, and a second surgery was required 1 year after the treatment. Clinical symptoms such as headache and visual disruption were rapidly alleviated after the neuroendoscopic procedure. No new visual disturbances, endocrinopathy, or hypothalamic dysfunction was observed during follow up. Conclusions Stereotactic radiotherapy for cystic craniopharyngioma after endoscopic fenestration can effectively control the tumor for a long period of time, improve the clinical symptoms and avoid endocrine diseases.

Objective: To determine the effect of a motor-specific neurotrophic factor, glial-derived neurotrophic factor (GDNF) on motor nerve regeneration. Methods: We used a nerve conduit filled with a fibrin-based delivery system that provided controlled release of GDNF during nerve regeneration. The motor branch of the rat femoral nerve was used to assess motor nerve regeneration across a 5-mm gap. Four experimental groups (n=5) were evaluated. These included GDNF with the fibrin-based delivery system (GDNF-DS group), fibrin alone(fibrin group), empty conduit (negative control group), and nerve isograft (positive control group). Nerves were harvested at 5 weeks for analysis by histomorphometry and electron microscopy. Results: At 5 mm distal to the conduit or isografts, the GDNF-DS group was not significantly different from the nerve isograft group in the following histomorphometric measures: total nerve fibers, percentage of neural tissue, and nerve density. The number of nerve fibers (respectively: 1 744±274 , 1 481±288) and the percentage of nerve tissue [(14.2±3.9)%, (11.0±2.2)%] in theisograft group and the GDNF-DS group were significantly higher than that in the fibrin group and the empty conduit group [(respectively: 538±93, 535±96) and the percentage of nerve tissue respectively: (4.3±1.6)%, (3.7±0.9)%]. There were no differences in fiber width among all groups. By electron microscopy, the GDNF-DS and isograft groups also demonstrated more organized nerve architecture than the fibrin alone and empty conduit groups. Conclusions The delivery of GDNF from the fibrin-based delivery system promotes motor nerve regeneration at a level similar to an isograft in the femoral motor nerve model. This study gives insight into the potential beneficial role of GDNF in the treatment of motor nerve injuries.

Objective To explore the expression levels of chemokine (C-C motif) ligand 18 (CCL18) in human glioma tissues and its effects on the invasion,migration and proliferation ofglioma cells.Methods (1) Sixty samples were harvested from the glioma which was excised surgically and confirmed pathologically from the patients at the Department of Neurosurgery,Affiliated Hospital to Binzhou Medical College from January 2012 to December 2017.Of the samples,by the WHO grading,26 belonged to grade Ⅱ,18 to grade Ⅲ and 16 to grade Ⅳ.Ten samples of normal brain tissue were harvested as controls from the contemporary patients who underwent intracranial decompression and excision due to brain injury.CCL18 mRNA expression was determined by real-time RT-PCR and CCL18 protein expression in tumor cells by immunochemically histological staining.(2) U251 glioma cells cultured in vitro were incubated with CCL18 serum-free culture media (0 ng/mL,5 ng/mL and 10 ng/mL) for 24 h before they were subjected to Transwell,scarification and CCK-8 assays to measure cellular invasion,migration and proliferation.Results (1) The expression of CCL18 mRNA was significantly increased in the order from normal brain,glioma of grade Ⅱ,glioma of grade Ⅲ to glioma of grade Ⅳ (P＜0.05);the expression of CCL18 protein was significantly increased in the order from glioma of grade Ⅱ,glioma of grade Ⅲ to glioma of grade Ⅳ (P＜0.05).(2) The 24 h Transwell assay for invasion showed that the number of transmembrane cells was significantly increased in the order from 0 ng/mL group to 5 ng/mL group to 10 ng/mL group (43.5±8.3,202.0±18.5 and 279.7±18.6 cells) (P＜0.05).The widths of scratch (pixels) in the scarification assay for migration were 498.4±75.3,381.3±21.4 and 347.7±14.2 at 12 h,and 299.5±15.3,284.6±7.8 and 237.3±20.6 at 24 h,respectively,showing significant differences between the groups of 0 ng/mL,5 ng/mL and 10 ng/mL recombinant CCL18 (P＜0.05).The cell growth in CCK-8 assay for proliferation was 1.000±0.019,1.260±0.094 and 2.070±0.138 fold at 24 h,respectively,also showing significant differences between the groups of 0 ng/mL,5 ng/mL and 10 ng/mL recombinant CCL18 (P＜0.05).Conclusions Expression of CCL18 in glioma is associated with the malignancy of the tumor.As CCL 18 promotes invasion,migration and proliferation of glioma cells,it may be a potential biomarker for detecting and grading human glioma.
