OBJECTIVE: To observe the clinical efficacy of Xujiang Xie's bloodletting therapy combined with Qingyan Lige decoction on acute pharyngitis with lung-stomach heat accumulation. METHODS: A total of 88 patients with acute pharyngitis of lung-stomach heat accumulation were randomly divided into an observation group (44 cases, 4 cases dropped out) and a control group (44 cases, 4 cases dropped out). The control group was treated with oral Qingyan Lige decoction, 150 mL each time, twice a day for 6 continuous days. On the basis of the treatment in the control group, Xujiang Xie's bloodletting therapy was applied at bilateral Shaoshang (LU11), Shangyang (LI1), and Erjian (EX-HN6) in the observation group, 0.1-0.5 mL of bloodletting per site, once every other day for 3 times in total. The TCM symptom and sign score, complete blood count (white blood cell [WBC] count, neutrophilic granulocyte percentage [NE%]), inflammation indexes (serum levels of C-reactive protein[CRP], interleukin[IL]-1β, IL-6, tumor necrosis factor [TNF]-α) and immune indexes (？？, ？？, ？？) of the two groups were observed before treatment and after 6 days of treatment, and the clinical efficacy was evaluated. RESULTS: After 6 days of treatment, the sore throat scores, redness and swelling scores of pharyngeal mucosa and uvula, pharyngeal dry and burning scores, hyperemia scores of posterior pharyngeal lymphoid follicles, chill and fever scores, total scores of TCM symptom and sign, WBC count, NE%, CRP, IL-1β, IL-6, TNF-α and ？？ in both groups were decreased compared with those before treatment (P<0.05), the above indexes in the observation group were lower than those in the control group (P<0.01, P<0.05, P<0.001). After 6 days of treatment, the levels of ？？ and ？？ in both groups were increased compared with those before treatment (P<0.05), and the above indexes in the observation group were higher than those in the control group (P<0.001). The total effective rate of the observation group was 95.0% (38/40), which was higher than 90.0% (36/40) in the control group (P<0.001). CONCLUSION Xujiang Xie's bloodletting therapy combined with Qingyan Lige decoction could improve the symptoms in patients with acute pharyngitis of lung-stomach heat accumulation, inhibit inflammatory response and improve immune function.

Objective To analyze the characteristics and drug resistance of pathogenic bacteria isolated from patients undergoing solid organ transplantation(SOT)at West China Hospital,Sichuan University in re-cent years,in order to provide a basis for empirical anti infective treatment after SOT surgery.Methods A retrospective analysis was conducted on the isolation of major pathogens and their resistance to common anti-biotics from various specimens collected from patients undergoing kidney transplantation(KT),liver trans-plantation(LTx),and lung transplantation(LT)at West China Hospital,Sichuan University from 2017 to 2022.Results A total of 1 077 non-duplicate strains of pathogens were isolated from the samples of patients with infections after SOT surgery during the 6-year period,of which approximately 74.8％(806/1 077)were Gram negative bacteria and 25.2％(271/1 077)were Gram positive bacteria.There were differences in the distribution of pathogenic bacteria among different types of SOT groups and different specimens.Compared to E.coli isolated from urine specimens,the strains of E.coli isolated from non-urinary specimens exhibited a higher resistance rate to common antimicrobial drugs(P＜0.05).The resistance rate of E.coli to β-lactam/β-lactamase inhibitor combinations(cefoperazone/sulbactam and piperacillin/tazobactam)in the LTx group was significantly higher than that in the KT group(P＜0.05).The overall proportion of multidrug-resistant bac-teria after SOT surgery was 11.3％(122/1 077).The proportion of carbapenem resistant Acinetobacter bau-mannii and carbapenem resistant Pseudomonas aeruginosa among the same group and type of pathogens in the LTx group(93.8％,37.5％)was significantly higher than that in the KT group(55.8％,9.2％).Conclusion The specimen types and strain distribution of pathogenic bacteria after different types of SOT surgery are different.The same pathogenic bacteria have different antibiotic resistance among different types of SOT groups and specimens.Therefore,it is necessary to strengthen the pathogen examination after different types of SOT and optimize the anti infection treatment plan related to transplantation based on drug sensitivity re-sults.

ObjectiveTo perform a predictive analysis of the quality marker（Q-Marker） for the anticoagulant activity of Kunning granules. MethodThe chemical components of Kunning granules were analyzed by ultra high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry（UHPLC-Q-TOF-MS/MS） on a Waters ACQUITY UPLC HSS T3 column（2.1 mm×100 mm， 1.8 μm） with the mobile phase of acetonitrile（A）-25 mmol∙L^-1 ammonium acetate aqueous solution（B） for gradient elution （0-5 min， 5%-22%A； 5-10 min， 22%-30%A； 10-15 min， 30%-95%A； 15-20 min， 95%-5%A； 20-30 min， 5%A）， flow rate of 0.2 mL∙min^-1， column temperature at 30 ℃， injection volume of 1 μL， electrospray ionization（ESI）， positive and negative ion detection modes. Interaction analysis between the targets of chemical components and the targets of abnormal uterine bleeding（AUB） was performed by network pharmacology， and the key components were screened through network topology analysis. The fingerprints of 10 batches of Kunning granules were established by high performance liquid chromatography（HPLC）， the anticoagulant activity of the granules was determined by blood coagulation method and fibrinogen plate method， and the spectrum-effective relationship was established. The components co-occurring in the topological analysis and spectrum-effective relationship were selected as Q-Markers， and their anticoagulant activities were verified and confirmed. ResultA total of 475 chemical components were identified from Kunning Granule， of which 22 key components such as salvianolic acid B， paeoniflorin， naringin and neohesperidin， were the potential material basis for the treatment of AUB. The spectrum-effective analysis showed that peaks 7（paeoniflorin）， 9（naringin）， 10（neohesperidin） and 11（salvianolic acid B） were the optimal principal components， and in vitro activity test showed that these four components could better characterize their anticoagulant activity. ConclusionSalvianolic acid B， paeoniflorin， neohesperidin and naringin may be Q-Markers for the anticoagulant activity of Kunning granules.

【Objective】 To investigate the effect of sinomenine hydrochloride （SH） on angiogenesis and the underlying mechanism in breast cancer. 【Methods】 The 4T1 orthotopic tumor model of breast cancer was utilized， and mice were treated with different dosage of SH to investigate the effect of SH on tumor growth. IHC staining of CD31 was used to evaluate angiogenesis within tumors under different treatment. ELISA was performed to measure the bFGF level within tumor extracellular fluid （TEF） and tumor cells to analyze the effect of SH on bFGF secretion and production. RT-qPCR was utilized to evaluate the effect of SH on the mRNA expression of bFGF in tumor cells. Kaplan-Meier Plotter was analyzed online to investigate the relationship between bFGF expression and the survival of patients with breast cancer. 【Results】 SH at 100 mg/kg could inhibit 4T1 orthotopic tumor growth compared with saline （P<0.05）， but SH showed little cytotoxicity in vitro under the tested concentrations. SH at 100 mg/kg suppressed the vessel area compared with saline （P<0.01）， and the concentration of angiogenic factor bFGF in TEF and tumor cells was decreased by SH treatment （P<0.05）， while the mRNA expression of bFGF in tumor cells was also downregulated by SH treatment （P<0.05）. Kaplan-Meier Plotter online analysis showed that elevated mRNA expression of bFGF in the primary tumor was associated with poorer OS， RFS and DMFS in patients with breast cancer （P<0.01）. 【Conclusion】 SH inhibits breast cancer growth by suppressing bFGF-induced angiogenesis， which enriches the pharmacological effects of this traditional Chinese medicine.

Objective: To investigate the physical properties of Ti-6Al-4V clasps generated by selective laser melting (SLM) with different construction directions and to compare these clasps with cast clasps, which could provide a basis for fabricating SLM clasps with high precision and excellent mechanical properties. Methods: Ti-6Al-4V clasps were fabricated by SLM at 0 degrees (SLM0 group), 45 degrees (SLM45 group) and 90 degrees (SLM90 group) (n = 12). Twelve clasps were cast by the casting method as the control group. Meanwhile, four metal abutments were cast randomly as the abutments of the four groups. X-ray was used to detect cracks in the clasps of each group. The roughness of the clasps was measured by confocal microscopy, the fitness tests between clasps and abutment were processed by stereomicroscopy, and the microstructure of clasps in each group was observed under a metallographic microscope to evaluate the physical properties. Results : There were 0-8 visible cracks in the casting group but no obvious defects in the SLM groups. The maximum surface roughness was observed in the cast group (18.102 ± 3.762) μm, while the minimum roughness was observed in the SLM90 group (5.942 ± 1.486) μm (P < 0.05). There was no statistically significant difference in surface roughness between the SLM0 group [(8.711 ± 2.378) μm] and the SLM45 group [(8.513 ± 1.161) μm]. Fitness was worst in the casting group [(68.445 ± 14.876) μm] and best in the SLM90 group [(33.417 ± 5.880) μm] (P < 0.05). There was no statistically significant difference in fitness between the SLM0 group [(52.917 ± 12.102) μm] and the SLM45 group [(50.889 ± 7.011) μm]. In addition, the growth direction of the β grains was roughly parallel to the build direction, and acicular α grains were present between β grains. SLM was composed of fine grains, while the cast group had large grains. Conclusions Specimens generated by SLM had finer grains than cast specimens. In addition, SLM90 clasps had the highest fitness and the lowest surface roughness.

OBJECTIVETo compare the efficacy differences between catgut implantation at stellate ganglion combined with oral administration of alendronate sodium and oral administration of alendronate sodium alone on postmenopausal osteoporosis (PO).

METHODSSixty patients of PO were randomly divided into an observation group and a control group, 30 cases in each one. The patients in the control group were treated with oral administration of alendronate sodium. Based on the treatment of control group, the patients in the observation group were treated with catgut implantation at stellate ganglion. The treatment was given once a week in the two groups; the consecution treatment of four weeks constituted one session, and totally six sessions were given. The changes of total syndrome score, bone mineral density of lumbar vertebra (L to L) and femeral neck (FN) and estradiol were observed before and after treatment; the clinical efficacy was compared between the two groups.

RESULTSCompared before treatment, the total syndrome score, bone mineral density of lumbar vertebra (L to L) and FN and estradiol were significantly improved after treatment (all <0.05); which were more significant in the observation group (all <0.05). Compared before treatment, the level of estradiol in the control group was not significantly changed after treatment (>0.05), while that in the observation group was significantly changed after treatment (<0.05). After treatment, the level of estradiol in the observation group was higher than that in the control group (<0.05). The total effective rate was 93.3% (28/30) in the observation group, which was significantly higher than 83.3% (25/30) in the control group (<0.05).

CONCLUSIONCatgut implantation at stellate ganglion combined with oral administration of alendronate sodium are superior to oral administration of alendronate sodium alone for postmenopausal osteoporosis, which improve the clinical symptoms, regulate the hormone level and increase bone mineral density.

OBJECTIVE: To analyze the differences of sleep respiratory parameters recorded by PSG and synchronous blood pressure measured by ambulatory blood pressure monitor between obstructive sleep apnea (OSA) patients with hypertension (HT) and simple OSA and simple HT; To determine the characteristics of sleep respiratory parameters and blood pressure changes in patient with OSA accompanied HT. METHOD: We chose the patients who were diagnosed simple HT (n=45) and simple OSA (n=50) and OSA with HT (n=56), Compared the sleep respiratory parameters and blood pressure changes between the three groups. Meanwhile the correlations about the sleep respiratory parameters and synchronization blood pressure were analyzed. RESULT: Compared with simple HT and simple OSA, OSA with HT has higher apnea hyponea Index (AHI) (P<0. 001), oxygen desaturation index (ODI), awake index (AI), wake after sleep onset (WASO) and the proportion of non-rapid eyemovement sleepl (N1) in total sleep time(TST), has lower mean arterial oxygen saturation (MSaO2), lowest arterial saturation oxygen (LSaO2), the proportion of slow wave sleep (SWS) and rapid eyemovement sleep (REM) in TST (P<0. 05). There were positive correlations between the systolic/diastolic blood pressure (SBP/ DBP) and AHI, ODI, AI, WASO and N1/TST (P<0. 05). Compared with simple OSA, the mean day systolic blood pressure (dMSP), mean night systolic blood pressure (nMSP), mean day diastolic blood pressure (dMDP), mean night diastolic blood pressure (nMDP) and mean night diastolic blood pressure (nMDP) were significantly decre- sed, meanwhile the difference between the average systolic/diastolic blood pressure day and night were significantly increased after continuous positive airway pressure (CPAP) treatment. OSA with HT has higher There were negative correlations between the SBP/DBP and MSaO2, LSaO2 (P<0. 05). Blood pressure mainly changed in the later sleep stage when the REM phase was increased. Blood pressure changes were characteristic of increasing DBP and decreasing SaO2. CONCLUSION There are significant differences between simple OSA and OSA with HT in the sleep respiratory parameters, which are closely related with changes of blood pressure in sleep stage; AHI is the high risk factor of the OSA with HT. PSG is a effective factor in estimating the OSA accompanied HT course of development and prognosis.
