OBJECTIVETo explore efficacy enhancing and detoxification roles of Jiedu Quyu Zishen Recipe (JQZR) in treating systemic lupus erythematosus (SLE) by studying its effect on Toll like receptor 9 (TLR9) signal pathway of murine macrophage cells after JQZR stimulated CpG oligodeoxynucletide (CpG ODN).

METHODSMurine macrophage cells in vitro cultured were randomly divided into 4 groups, i.e., the blank serum group, the CpG ODN stimulus group, the CpG ODN + dexamethasone group, the CpG ODN + medicated serum group. Murine macrophage cells were collected after 24-h intervention. The expression of TLR9, myeloid differentiation factor 88 (MyD88), NF-KB, IFN-α mRNA were analyzed by RT-PCR. The expression of TLR9 and NF-κB protein were analyzed by Western blot. Changes of the NF-KB transcriptional activity were assayed by Dual-Luciferase reporter assay system.

RESULTSmRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were enhanced, showing statistical difference when compared with those of the blank serum group (P <0. 05, P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of MyD88, NF-κB, and IFN-α, the protein expression of NF-κB and the NF-κB transcriptional activities decreased in the CpG ODN + dexamethasone group with statistical difference (P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were decreased in CpG ODN+ medicated serum group with statistical difference (P <0. 01).

CONCLUSIONEfficacy enhancing and detoxification roles of JQZR in treatment of SLE might be realized through regulating TLR9 signal pathways.

Abstract: Objective　To investigate the clinical and laboratory characteristics of pulmonary infection caused by Nocardia otitidiscaviarum. Methods　The clinical data of a patient with pulmonary infection caused by Nocardia otitidiscaviarum were reported, and the clinical characteristics, laboratory characteristics and drug sensitivity of pulmonary infection caused by Nocardia otitidiscaviarum were summarized in combination with the relevant literature at home and abroad from January 2010 to December 2022. Results　A 67-year-old female patient was admitted to the hospital on June 30, 2020 because of "repeated chest tightness and shortness of breath for 3 years, aggravated cough, expectoration and fever". The sputum, alveolar lavage fluid and blood of the patient were collected for culture, and the detected pathogenic bacteria were identified. There are pathogenic bacteria growing in sputum and alveolar lavage fluid, which are identified as Nocardia otitidiscaviarum by Autof ms mass spectrometer. According to the results of pathogenic bacteria and the patient's condition, meropenem combined with compound sulfamethoxazole tablets were given anti-infection treatment, and the patient's condition improved and discharged. Conclusion　The clinical manifestations and imaging features of nocardiosis are lack of specificity, and are prone to misdiagnosis and missed diagnosis. Etiology is the key to disease diagnosis, and clinical examination and culture should be conducted in time.

OBJECTIVE: To investigate the relationship between platelet activating factor (PAF) and occurrence of hepatorenal syndrome (HRS). METHODS: A total of 57 cases of patients with liver cirrhosis or hepatitis gravis were enrolled. The serum concentrations of PAF, lipopolysaccharide (LPS) and prothrombin activity (PTA), total bilirubin, and serum creatinine were detected in patients combined with HRS and in patients without HRS in hospital at the term. The correlations among the PAF, LPS, and the function of liver and kidney were analyzed. RESULTS: The concentrations of PAF and LPS in the patients combined with HRS were significantly higher than those patients without HRS. There were linear correlations between the PAF and LPS level, the total bilirubin level and PAF level, the PAF level and serum creatinine level. CONCLUSION The PAF associates with the occurrence of HRS. The PAF may mediate the occurrence of HRS induced by LPS. The PAF level may forecast whether patients with liver failure will take place HRS.

To determine the optimal condition of pollen germination. The pollen of Prunella vulgaris was cultured in vitro. Pollen germination rates were recorded using 10% H3BO4, 30% Ca(NO3)2, 20% MgSO4 and 10% KNO3 as the basic mineral medium with PEG of different molecular weight, sucrose of various density and multiple pH value. The rates were also measured under different cultivation temperature and pollen acquisition time. The optimal condition of pollen germination is 10% H3 BO4, 30% Ca(NO3)2, 20% MgSO4, 10% KNO3, and 25% PEG-4000 as the medium, with pH about 6. 5 and pollen acquired at the beginning of blossom.

Objective To evaluate the changes of nerve conduction velocity in degenerative rabbit sciatic nerve authograft induced by 60Co irradiation after orthotopic replantation. Methods A 30-mm-long segment was severed from normal adult rabbit sciatic nerve and exposed to 60Co irradiation at the dose of 350 Cry to induce neural degeneration. The nerve segment was then replanted orthotopicaily, and the nerve conduction velocity was determined using electrophysiological test at 4, 6 and 8 months after the replantation. Results At 6, 8 months after the replantation, the nerve conduction velocity in the degenerative nerve autograft showed no significant difference from that in normal sciatic nerve (P>0.05). But at 4 months after the replantation, the nerve conduction velocity in the autograft was significantly lower than the normal velocity (P<0.05). Conclusion The nerve conduction velocity can be obtained by replantation of a long (3 mm) degenerative nerve segment due to 60Co irradiation.

OBJECTIVETo investigate the effect of Shengdi injection on rat model of lung inflammation.

METHODThe rat model was established by intratrachea instillation of lipopolysaccharides (LPS). The total and different white blood cell counts in bronchoalvoelar lavage fluid (BALF) were performed and the level of tumor necrosis factor-alpha (TNF-alpha), superoxide anion radical (O2-) and myeloperoxidase (MPO) was measured, as well as pathologic change of pulmonary tissue was tested.

RESULTShengdi injection could depress the increasing of the amount of total white blood cells and neutrophils and inhibit the increasing of TNF-alpha, O2-, MPO caused by LPS, as well as relieve the pathologic change including Neutrophils infiltrating and mucous edema in tracheae after intravenous administration. While it did not show the effect on monocyte, and histological lesion of the lung tissue.

CONCLUSIONShengdi injection shows some anti-inflammatory effect in rat lung induced by LPS and it can be concluded tentatively that anti-inflammatory, inhibiting the release of cytokine and inflammatory medium, and antioxidation are some of the mechanism of its effect on COPD.

OBJECTIVETo study the clinical application value of middle segment pancreatectomy in the treatment of benign tumors of the amphi-neck of the pancreas.

METHODSFifteen cases were retrospectively analyzed treated from November 2005 to June 2009. There were 3 male and 12 female aging from 30 to 50 years. They all received middle segment pancreatectomy for benign tumors of the amphi-neck of the pancreas.

RESULTSThere was no death during perioperative period. All the 15 patients received middle segment pancreatectomy. Fourteen of them received the closure of broken ends of pancreatic head, pancreaticojejunostomy (mono-anastomosis) and the rest one received dipl-anastomosis. Postoperative pathology showed that in the 15 patients, 1 got solid-pseudopapillary tumor of the pancreas, 3 got non-functional islet cell tumor, 11 got cystadenoma of pancreas. Three of them got pancreatic fistula and were self cured in 3 months. Follow-up visits to all the patients kept in the following 2 to 45 months. There was no death. No patients got new-onset diabetes and pancreatic pseudocyst. And their tumors were not relapsed.

CONCLUSIONSThere is an exact therapeutic effect of middle segment pancreatectomy for benign tumors of the amphi-neck of the pancreas. The treatment has little function damage to patients' endocrine and external secretion. The incidence rate of pancreatic fistula in middle segment pancreatectomy is higher than that in pancreaticoduodenectomy. As long as the drainage is kept unobstructed, most of the pancreatic fistula can be self cured.
