Huangqintang， with its accurate efficacy， is a classic formula specialized in treating dysentery recommended and promoted by medical experts from successive generations， and it was included in the Catalogue of Ancient Classic Prescriptions （the Second Batch， Han Chinese medicine prescriptions） published by the National Administration of Traditional Chinses Medicine （TCM） in 2023. The method of bibliometrics was applied in this study to conduct textual research on the classic formula Huangqintang and provide a literature reference for the development of modern preparations of Huangqintang. A total of 2 026 pieces of ancient literature were searched with "Huangqintang" as the key word， and 23 pieces of effective data were selected， involving 15 ancient TCM books. The historic evolution， composition， dosage， origin， processing methods， preparation and decocting methods， efficiency， and application of Huangqintang were carefully reviewed. The results showed that Huangqintang was first recorded in the Treatise on Febrile Diseases written by ZHANG Zhongjing. It has the effect of clearing heat， stopping dysentery， regulating the middle， and downbearing counterflow and has become one of the classic formulas widely used in clinical practice. Because of its accurate efficacy， medical experts from later generations have modified it from its original composition. Though many prescriptions have different names， it is the manifestation of physicians' inheritance and development of the thought of ZHANG Zhongjing. Ancient literature showed this prescription had wide indications yet centered on digestive system diseases such as dysentery and abdominal pain. Modern applications of Huangqintang involve digestive， respiratory， ophthalmology and otolaryngology， gynecological， skin， musculoskeletal system， and connective tissue， and this prescription has great potential in treating ulcerative colitis， diarrhea， acute enteritis， and damp-heat dysentery. Through a systematic textual excavation and review of the ancient literature about Huangqintang， the paper has confirmed its key information， so as to provide a scientific basis for the clinical application and new drug development of classic formulas.

Nocardiosis is a collective term for tissue and organ damage caused by Nocardia infection.Solid organ transplant recipients(SOTR)are at an increased risk of various pathogen infections,including Nocardia infection,due to immunosuppressive therapy which weakens their immune function.The diagnosis of nocardiosis has been challenging in the past.With the advent of molecular biology and other diagnostic methods,the diagnostic rate has significantly improved.Nocardia not only prone to cause necrotic pulmonary lesions but also invade other organs and tissues,such as intracranial infections and skin soft tissue infections,and can develop into systemic disseminated infections.For SOTR,nocardiosis is a potentially fatal disease with a fatality as high as 30%.Therefore,this article reviews the clinical characteristics of common nocardiosis in SOTR,new diagnostic technologies,and different anti-infective treatment strategies,aiming to provide a reference for the prevention and treatment of nocardiosis in clinical SOTR.

Type 2 diabetes mellitus （T2DM） can be categorized into “xiao ke （消渴）” in traditional Chinese medicine （TCM）. The theory of “yin restricts fire” originates from Inner Canon of Yellow Emperor （《黄帝内经》） which states that “yin essence restricts chief fire”， and the crucial pathogenesis and treatment of xiao ke coincide with this theory. ZHANG Zhongjing^，s three prescriptions of Jizizhuang （egg yolk） are Baihe Jizizi Decoction （百合鸡子汤）， Huanglian Ejiao Decoction （黄连阿胶汤） and Painong Powder （排脓散）， which are scattered in different chapters of Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》）. By analyzing and summarizing the mechanism and characteristics of the three prescriptions， it is found that the three prescriptions are in line with the characteristics of “yin restricts fire” and the pathogenesis of T2DM. These three prescriptions are composed of Jizizhuang and different medicinals. Baihe Jizizi Decoction is composed of Jizizhuang and Baihe （Bulbus Lilii）， and can be used to treat T2DM and mental diseases. Huanglian Ejiao Decoction is composed of Jizihuang， Ejiao （Colla Corii Asini）， Shaoyao （Radix Paeoniae Alba seu Rubra）， Huanglian （Rhizoma Coptidis） and Huangqin （Radix Scutellariae）， which could be used to treat T2DM and cardiorenal system diseases. Painong Powder is composed of Jizizhuang， Shaoyao， Jiegeng （Radix Platycodonis） and Zhishi （Fructus Aurantii Immaturus）， which can be used to treat T2DM and carbuncle. Therefore， based on the theory of “yin restricts fire” and “many different diseases can be treated in the same wa”， this paper propose that the three Jizihuang prescriptions could be used in T2DM， which could provide ideas for clinical treatment.

Objective:To explore the relationship between the diameter of drainage used in closed thoracic drainage (CTD) and the prognosis of patients with thoracic trauma.Methods:This study was a retrospective cohort study, a total of 146 patients who were admitted to the 971st Navy Hospital due to thoracic trauma from April 2017 to June 2021 and received closed thoracic drainage were selected as the research subjects. According to the prognosis, they were divided into a good group ( n=96) and a poor group ( n=50), and the clinical efficacy, general data and postoperative complications of the two groups were compared and analyzed. Multivariate Logistic regression was used to analyze the risk factors for poor prognosis, and a nomogram prediction model was established, and the model was evaluated. The relationship between the size of drainage diameter and the prognosis of patients with thoracic trauma was analyzed by Pearson correlation. The normally distributed measurement data was expressed by the ( ± s), and the independent samples t test was used for comparison between groups; The chi-square test was used for comparison of count data between groups. Results:The clinical efficacy of CTD was good, with a total effective probability of 87.67%; and 3 weeks after surgery, the patient′s prognosis was good, with a good prognosis probability of 65.75%. Logistic analysis showed that age 60 years old ( OR=1.501, 95% CI: 1.105-2.177), excipient replacement time of 2-3 d ( OR=2.543, 95% CI: 1.729-3.168), drainage bottle higher than thoracic cavity ( OR=1.692, 95% CI: 1.314-2.482), long wound healing time ( OR=1.971, 95% CI: 1.479-2.720), frequent cough ( OR=2.259, 95% CI: 1.564-2.924), and drainage tube diameter 16 F ( OR=3.087, 95% CI: 2.074-3.793) were independent risk factors for poor prognosis ( P<0.05). The size of drainage diameter was positively correlated with hospitalization and wound healing time, pain VAS score ( P<0.05), and negatively correlated with Barthel Index ( P<0.05). Conclusion:Drainage tube diameter 16 F is one of the independent risk factors for poor prognosis of patients. The smaller the drainage diameter, the shorter the postoperative hospital stay, faster wound healing, lighter pain and stronger ability of life and activity.

Emphysematous cystitis is a rare inflammation of the bladder, which can be life-threatening in severe cases. A senior gentleman with emphysematous cystitis was recently admitted to our hospital. He got bilateral renal hydronephrosis and bilateral terminal pneumatosis of the ureter. The comorbidity was prostatic hyperplasia and diabetes. After indwelling catheter , glucose levels control and anti-infection treatment for 3 days, the repeated CT showed the gas inside the bladder the end of ureter decreased significantly. The blood routine, urine routine, renal function was better than before. The patient was instructed to continue anti-infection treatment. The above laboratory examination indicators returned to normal after a week's re-examination.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Objective To observe the results and reality of transurethral resection of bladder tumor with preexcitation of electric cutting loop in the prevention of obturator nerve reflex.Methods The clinical data of 186 patients with bladder tumors admitted from January 2015 to August 2018 were retrospectively analyzed.There were 112 males and 74 females aged 35 to 83 years,average (59 ± 11)years.76 patients were admitted because of intermittent gross hematuria and 110 patients were admitted because of physical check-up.All patients underwent ultrasound,CT (plain scan/enhancement) and cystoscopy before operation.The pathological diagnosis of cystoscopy biopsy was bladder urothelial cell carcinoma.There were 105 cases clinical stage Ta stage,81 cases of T1 stage.There were 103 single cases and 39 multiple cases of non-muscular invasive bladder.According to the different surgical techniques,the patients were divided into two groups:the pre-excitation group and lateral incision group.There were 142 cases in pre-excitation group.In the pre-excitation group,the tumors were removed routinely by the resection ring.When the resection ring was far away from the tumors,the pedal switch was pressed to excite the resection ring.The resection ring was moved to the location of the tumors,and the tumors were cut to the muscular layer.The operation was completed after 2 cm electric cauterization around the wound and hemostasis.In the lateral incision group,the tumors were removed routinely by the electric resection ring.The operation time,incidence of obturator nerve reflex,incidence of bladder perforation,amount of bleeding,retention time of catheter,pathological grading,risk grading,hospitalization time and recurrence rate of tumors at 6 months after operation were compared between the two groups.Results The operation was successfully completed in both groups,and there was no transition to open operation.In the pre-excitation group,the operation time was 10 minutes to 56 minutes,with an average of (28 ± 12) minutes,and the intraoperative blood loss ranged from 5 ml to 70 ml,with an average of (35 ± 15) ml.In the lateral incision group,the operation time was 15 minutes to 65 minutes,with an average of (28 ± 11) minutes,and the blood loss was 10 ml to 80 ml,with an average of (40 ± 15) ml.There was no significant difference in operation time and blood loss between the two groups (P ＞ 0.05).There were only 3 cases of obturator nerve reflex in preexcitation group,the incidence was 2.1％.There were 13 cases of obturator nerve reflex in lateral resection group,the incidence was 29.5％.There was significant difference of nerve reflex incidence between the two groups (P ＜ 0.05).Conclusions In transurethral resection of bladder tumors,the method of pre-excitation of plasma resection ring can effectively decrease obturator nerve reflex and make the operation safer.

Objective To study the feasibility,efficacy and safety of ultrasound-guided percutaneous radiofrequency ablation (RFA) in the treatment of hepatocellular carcinoma (HCC) in the caudate lobe.Methods From November 2006 to June 2017,31 patients with 31 HCCs located in the caudate lobe were treated with percutaneous RFA at the First Affiliated Hospital of Sun Yat-sen University.The treatment efficacy,complications,and the local tumor progression (LTP),disease-free survival (DFS) and overall survival (OS) rates were analyzed.Results Residual tumors were detected in 5 patients after the first treatment.Complete necrosis was achieved in all the patients after the second treatment.The mean number of ablation sessions was 1.16±0.37.At a follow-up period which ranged from 3 to 65 months,19 patients had died,10 patients were still alive,and 2 patients were lost to follow-up.The 1-,2-,3-,and 5-years OS rates were 78.4％,48.5％,12.1％ and 12.1％,respectively.On follow-up,9 caudate lobe HCC lesions were detected to have LTP.The 1-,2-,and 3-years LTP rates were 21.5％,41.6％ and 41.6％,respectively;while the 1-,2-,and 3-years DFS rates were 22.3％,11.2％ and 11.2％,respectively.Ablationrelated complications were detected in 4 patients.Conclusions Ultrasound-guided percutaneous RFA was safe and effective for patients with HCC in the caudate lobe.These patients should be followed-up closely to detect LTP.

Objective To investigate the beneficial role of synbiotics in the intestinal microbiota of patients with chronic functional constipation (CFC).Methods According to the inclusion and exclusion criteria,6 patients with CFC were enrolled with their fresh fecal samples collected,after a continuous treatment of one month their fresh fecal samples collected again.Meanwhile,6 healthy volunteers were enrolled as the control group with their fresh fecal samples collected.All samples were transported with ice and stored in -80 ℃ refrigerator,and were analyzed by metagenomics sequencing.Results After 4 weeks of symbiotic treatment,the intestinal microbiota had changed in species in patients with CFC.Bacteria of Escherichia_ coli,Clostridium_ sp._ SS2/1 and Clostridium_ sp._ 7_ 3_ 54FAA,which were rich in the people with constipation,decreased in abundance after the treatment.Bacteria of Lactobacillus_ oris and Bifidobacterium _ animalis,which were rich in the healthy people,increased in content after the treatment.Bacteria of Veillonella_ parvula,Veillonella_ sp._ 6_ 1_ 27,Veillonella_ sp._ 3 _ 1_ 44 which were rich in the healthy people,decreased in content after the treatment.LEfSe analysis showed that Parabacteroides distaso nis,Escherichia_ coli and Enterobacter-cloacae were the specific species of the three groups respectively.Conclusion Synbiotics can change the intestinal microbiota showing therapeutic effect,thus can be used as a novel clinical treatment method.

Objective To investigate the influence of infection factors on kidney transplantation after organ donation and possible countermeasures.Methods Thirty-seven cases of kidney transplantation in Organ Transplantation Center of Qianfoshan Hospital Affiliated to Shandong University from January 2014 to December 2016 were retrospectively analyzed.The patients were divided into two groups according to perioperative infection prevention programs:42 patients with postoperative routine use of cephalosporins or penicillin for 2 weeks,and 95 patients with postoperative application of carbapenems + micafungin.Postoperative infection rate,occurrence time,pathogen infection;donor age,perioperative pathogens of donor and receptor (organ preservation solution,drainage fluid,urine,sputum samples),acute rejection,delayed graft function (DGF),diabetes mellitus,and the use of immunosuppressive agents were recorded.Results The infection rate in carbapenem + micafungin group was 12.6％,and the infection rate in cephalosporin or penicillin group was 19.4％ (P＜0.05).Pathogen positive detection rate of the drainage fluid,urine and sputum was lower in carbapenems + micafungin group than that in cephalosporins or penicillin (P＜0.05).Within 2 weeks after operation,the detection rate of bacteria and fungi in the carbapenems +micafungin infection prevention group was lower than that in the control group (P＜0.05).There was no significant difference in the detection of viruses (P＞0.05).There were no significant differences in the detection of pathogens among the two weeks to six months after surgery (P＞ 0.05).Donor infection,acute rejection,DGF,and diabetes mellitus were the risk factors for postoperative infection (P＜0.05).Conclusion The application of carbapenems and micafungin can reduce the incidence of infection for the early stage of DCD kidney transplantation.Donor infection,acute rejection,DGF and diabetes mellitus are all risk factors for the postoperative infection.
