ObjectiveTo observe the clinical efficacy and relative mechanism of the Modified Wenshen Yixin Formula （温肾益心方加减， MWYF） as an auxiliary treatment of coronary heart disease （CHD） complicated with hypothyroidism of spleen-kidney yang deficiency. MethodsA total of 135 CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency were included and divided into control group （67 cases） and experimental group （68 cases） according to the patients' wishes of herbal medicine administration. The control group was given conventional western medicine， while the treatment group was additionally given MWYF， 1 dose per day； both groups were treated for 8 weeks. The traditional Chinese medicine （TCM） syndrome scores， angina scores， SF-36 scores， thyroid function indicators including thyroid stimulating hormone （TSH）， thyroxine （T4） and triiodothyronine （T3）， as well as serum cyclic adenosine monophosphate （cAMP）， cyclic guanosine monophosphate （cGMP）， monocyte chemoattractant ligand 2 （CCL2）， and tumor necrosis factor-related activator protein （CD40L） levels before and after treatment were compared between the two groups. The dosage and reduction and discontinuation rate of thyroid hormone preparations after treatment were compared between the two groups. The effectiveness regarding TCM syndrome and angina pectoris was evaluated， and the safety was assessed. ResultsBias was adjusted by matching on propensity score， and 102 cases were finally included in the statistical analysis， with 51 cases in each group. The total effective rate regarding TCM syndrome ［94.12% （48/51） versus 64.71% （33/51）］， the total effective rate regarding angina pectoris ［80.39% （41/51） versus 62.75% （32/51）］， and the reduction and discontinuation rate of thyroid hormone preparation ［39.21% （20/51） versus 5.88% （3/51）］ were significantly higher in the experimental group than those in the control group （P＜0.05 or P＜0.01）. After treatment， the total TCM syndrome score， individual scores of major symptoms ， the major symptoms score， the secondary symptoms score， angina pectoris score， and TSH level were significantly reduced （P＜0.01）， while all dimensions of SF-36 scores， T4， T3， and cAMP levels significantly increased in both groups （P＜0.05 or P＜0.01）. The dosage of thyroid hormone preparations and the levels of cGMP， CCL2， and CD40L in the experimental group significantly decreased after treatment （P＜0.01）. When compared between the two groups after treatment， the total TCM syndrome score， the major symptoms score， the scores of individual major symptom （chest tightness， chest pain， fear of cold， cold limbs， waist and kness soreness and weakness）， the secondary symptoms score， angina pectoris score， TSH， cGMP， CCL2， and CD40L levels of the experimental group were significantly lower than those of the control group （P＜0.05 or P＜0.01）， while all dimension scores of SF-36， T4， T3， and cAMP levels were significantly higher （P＜0.01）. A total of three adverse events occurred during treatment， none of which were judged to be related to the interventions of this study. ConclusionMWYF can significantly ameliorate the TCM syndrome， angina pectoris， quality of life and thyroid function in CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency， and can promote the reduction and disconti-nuation of thyroid hormone preparations. The mechanism may be related to the regulation of cAMP/cGMP balance， the regulation of hypothalamic-pituitary-thyroid metabolic axis and the reduction of immune inflammation.

In infants with severe bronchopulmonary dysplasia(sBPD),severe pulmonary lobar emphysema may occur as a complication,contributing to significant impairment in ventilation.Clinical management of these infants is extremely challenging and some may require lobectomy to improve ventilation.However,prior to the lobectomy,it is very difficult to assess whether the remaining lung parenchyma would be able to sustain adequate ventilation postoperatively.In addition,preoperative planning and perioperative management are also quite challenging in these patients.This paper reports the utility of selective bronchial occlusion in assessing the safety and efficacy of lobectomy in a case of sBPD complicated by severe right upper lobar emphysema.Since infants with sBPD already have poor lung development and significant lung injury,lobectomy should be viewed as a non-traditional therapy and be carried out with extreme caution.Selective bronchial occlusion test can be an effective tool in assessing the risks and benefits of lobectomy in cases with sBPD and lobar emphysema.However,given the technical difficulty,successful application of this technique requires close collaboration of an experienced interdisciplinary team.

Objective To explore preemptive analgesic effect of preoperative intramural tramadol injection in percutaneous kyphoplasty(PKP)of vertebrae following local anesthesia.Methods From August 2019 to June 2021,118 patients with thora-co lumbar osteoporotic fractures were treated and divided into observation group and control group,with 59 patients in each gruop.In observation group,there were 26 males and 33 females,aged from 57 to 80 years old with an average of(67.69±4.75)years old;14 patients on T11,12 patients on T12,18 patients on L1,15 patients on L2;tramadol with 100 mg was injected intramuscularly half an hour before surgery in observation group.In control group,there were 24 males and 35 females,aged from 55 to 77 years old with an average of(68.00±4.43)years old;19 patients on T11,11 patients on T12,17patients on L1,12 patients on L2;the same amount of normal saline was injected intramuscularly in control group.Observation indicators included operation time,intraoperative bleeding,visual analogue scale(VAS)evaluation and recording of preoperative(T0),intraoper-ative puncture(T1),and working cannula placement(T2)between two groups of patients,at the time of balloon dilation(T3),when the bone cement was injected into the vertebral body(T4),2 hours after the operation(T5),and the pain degree at the time of discharge(T6);adverse reactions such as dizziness,nausea and vomiting were observed and recorded;the record the patient's acceptance of repeat PKP surgery.Results All patients were successfully completed PKP via bilateral pedicle ap-proach,and no intravenous sedative and analgesic drugs were used during the operation.There was no significant difference in preoperative general data and VAS(T0)between two groups(P＞0.05).There was no significant difference in operation time and intraoperative blood loss between the two groups(P＞0.05).VAS of T1,T2,T3,T4 and T5 in observation group were all lower than those in control group(P＜0.05),and there was no significant difference in T6 VAS(P＞0.05).T6 VAS between two groups were significantly lower than those of T0,and the difference was statistically significant(P＜0.05).There was no signifi-cant difference in incidence of total adverse reactions between two groups(P＞0.05).There was a statistically significant differ-ence in the acceptance of repeat PKP surgery(P＜0.05).Conclusion Half an hour before operation,intramuscular injection of tramadol has a clear preemptive analgesic effect for PKP of single-segment thoracolumbar osteoporotic fracture vertebral body under local anesthesia,which could increase the comfort of patients during operation and 2 hours after operation,and improve patients satisfaction with surgery.

Objective To investigate the clinical effect of minimally invasive transforaminal lumbar interbody fusion(Mis-TLIF)technique combined with preoperative position reduction in the treatment of spondylolisthesis and summarize its advan-tages.Methods Between July 2016 and July 2022,60 patients with lumbar isthmic spondylolisthesis were retrospectively ana-lyzed,including 26 males and 34 females,with an average age of(51.32±4.24)years old ranging from 35 to 72 years old.They were divided into observation group and control group according to the operation methods.There were 30 patients in the obser-vation group,including 12 males and 18 females;the age ranged from 35 to 71 years old with an average of(51.80±6.38)years old,the course of disease ranged from 12 to 60 months with an average of(24.17±1.98)months;there were 18 cases of L4 spondylolisthesis and 12 cases of L5 spondylolisthesis;according to Meyerding classification,there were 20 cases of grade Ⅰspondylolisthesis and 10 cases of grade Ⅱ.The observation group was treated with preoperative postural reduction combined with intraoperative reduction assisted minimally invasive transforaminal lumbar fusion via Quadrant channel(Mis-TLIF).There were 30 patients in the control group,including 14 males and 16 females,with an average of(50.00±4.24)years old ranging from 36 to 72 years old;the course of disease ranged from 12 to 60 months with an average of(23.70±1.53)months;there were 16 cases of L4 spondylolisthesis and 14 cases of L5 spondylolisthesis;according to Meyerding classification,there were 19 cases of grade Ⅰ spondylolisthesis and 11 cases of grade Ⅱ.The control group was treated with open transforaminal lumbar interbody fusion(Open-TLIF).The differences of operation time,intraoperative and postoperative blood loss,hospital stay,radiation exposure time and complications between the two groups were analyzed.Visual analogue scale(VAS),Oswestry disability index(ODI)and Japanese Orthopaedic Association(JOA)score were used to evaluate the clinical effect.X-ray and CT were followed up to evaluate the interbody fusion.Results All patients were followed up for 12 months.There was no signifi-cant difference in operation time,VAS of low back pain,slip angle and slip rate between two groups(P＞0.05).The intraoperative and postoperative blood loss in the observation group(165.50±15.56)ml and(59.17±10.59)ml were less than those in the con-trol group(259.33±35.32)ml and(165.33±29.56)ml(P＜0.05).The length of hospital stay in the observation group(3.53±0.68)days was less than that in the control group(5.20±0.41)days(P＜0.05).The intervertebral space height,slip angle,slip rate,ODI,VAS and JOA scores were significantly improved in the two groups at the final follow-up(P＜0.05).There were signifi-cant differences in ODI[(9.93±1.11)％vs(10.93±1.11)％]and JOA[(26.07±1.01)points vs(25.43±1.25)points]between the observation group and the control group at the final follow-up(P＜0.05).Conclusion In the treatment of spondylolisthesis,preoperative position reduction combined with intraoperative reduction assisted Mis-Tlif technique has advantages of less trau-ma,less bleeding and shorter hospitalization period than traditional open surgery.It is a safe and effective technique.

OBJECTIVE: To investigate the safety and the short-term efficacy of venetoclax combined with azacitidine followed by cladribine (VAC regimen) in children with refractory/ relapsed acute myeloid leukemia (AML). METHODS: The clinical data, treatment outcomes, complications, and blood product consumption of 6 children with refractory/relapsed AML treated with VAC regimen in the Children's Hospital of Soochow University from August 2021 to December 2021 were retrospectively analyzed. RESULTS: Among the 6 children, there were 1 male and 5 females. 5 cases were refractory AML, and 1 case was relapsed AML, which recurred again 16 months after allogeneic hematopoietic stem cell transplantation. 4 children were accompanied by chromosomes or genes that predicted poor prognosis, such as RUNX1, FLT3-ITD, KMT2A exon 2-exon 8 dup, MLL-AF6, 7q-, KMT2A exon 2-exon 10 dup, etc. After received VAC regimen, 4 cases achieved CR+CRi, 1 case achieved PR (only MRD did not relieve, MRD was 0.59%), and 1 case was NR (but the proportion of bone marrow blasts decreased). All 6 patients had grade Ⅳ neutropenia, and 4 patients had grade Ⅳ thrombocytopenia. During the period of neutropenia, none of the 6 children developed symptoms of infection such as fever, cough, and diarrhea. No treatment-related death occurred. CONCLUSION Venetoclax combined with azacitidine followed by cladribine provides a new treatment option for patients with relapsed/refractory AML who have poor efficacy in early induction remission theragy, showing good efficacy and safety.

This study was aimed at identifying species of ticks and investigating infections with tick-borne pathogens a-mong people in Yadong,Tibet.The total of 23 ticks(Ixodes and Haemaphysalis)collected from livestock in Yadong,Tibet in July 2021,the gene sequences of cytochrome oxidase subunitⅠ(COX Ⅰ),mitochondrial 16S ribosomal DNA(16S rDNA)and mitochondrial 12S ribosomal DNA(12S rDNA)were identi-fied on the basis of molecular biology classification.The gene sequences of spotted fever group rickettsia(SFGR),Borrelia burgdorferi,Francisella tularensis and Coxiella burnetii in ticks were amplified by PCR and sequenced,and phylogenetic ana-lyses were performed.In addition,184 serum samples collected from Yadong in 2021 were screened for antibodies to Lyme dis-ease,Q fever,spotted fever,and tularemia by ELISA,and infections with tick-borne pathogens in Yadong were comprehen-sively analyzed.The ticks(Ixodes)collected in Yadong,Tibet,were grouped into two categories.The COX Ⅰ,16S rDNA,and 12S rDNA gene sequences of the ticks had 99.5％,97.57％,and 99.12％ similarity,respectively,to those of Ixodes nuttallia-nus in GenBank.The similarities between the COX Ⅰ and 16S rDNA gene sequences of another Ixodes tick species and the COXⅠ and 16S rDNA gene sequences of Ixodes ovatus in GenBank were 88.29％ and 95.75％,respectively.The similarity between the COX Ⅰ,16S rDNA,and 12S rDNA gene sequences of Haemaphysalis ticks and those of Haemaphysalis Tibet in GenBank were 96.04％,96.17％,and 97.47％,respectively.The sequence amplification results for Borrelia burgdorferi,Francisella tularensis,and Coxsiella burnetii in 23 ticks were negative,whereas gltA gene amplification of spotted fever group Rickettsia in 23 ticks was positive.The similarity of gltA gene sequences with respect to those of Candidatus Rickettsia tarasevichiae,Rickettsia raoultii,Rickettsia canadensis,and a Rickettsia endosymbiont of Eucalyptus brunneri in GenBank was 96.77％,96.76％,95.35％,and 95.35％,respectively.Among 184 serum samples from Yadong,the positivity rates of Lyme disease,Q fever,spotted fever,and tularemia were 6.52％,12.50％,8.70％,and 10.87％,respectively.These results indicated that the 23 parasitic ticks collected in Yadong,Tibet,in July 2021 were Ixodes nuttallianus,Ixodes ovatus and Haemaphysalis ti-betensis,and 23 ticks were infected with SFGR.Lyme disease,Q fever,spotted fever,and tularemia infection were prevalent in the population of Yadong.Therefore,efforts to control tick-borne diseases must be strengthened.

Background: The common reference intervals (RIs) for thyroid hormones currently used in China are provided by equipment manufacturers. This study aimed to establish thyroid hormone RIs in the population of Lanzhou, a city in the subplateau region of northwest China, and compare them with previous reports and manufacturer-provided values. Methods: In total, 3,123 individuals (1,680 men, 1,443 women) from Lanzhou, an iodine-adequate area of China, perceived as healthy were selected. The Abbott Architect analyzer was used to determine the serum concentration of thyroid hormones. The 95% RI was estimated using the 2.5th and 97.5th percentiles as the lower and upper reference limits, respectively. Results: The serum levels of thyroid-stimulating hormone (TSH), total triiodothyronine (TT3), antithyroglobulin (ATG) antibody, and antithyroid peroxidase (ATPO) antibody levels were significantly correlated with sex (P<0.05). TSH, total thyroxine (TT4), and ATPO levels were significantly correlated with age (P<0.05). The serum levels of TSH, ATG, and ATPO in men were significantly lower than in women; in contrast, the serum TT3 level was significantly higher in men than in women (P<0.05). Serum TSH, TT3, TT4, and ATG levels differed across age groups (P<0.05), but no such variation was observed for ATG levels (P>0.05). The established RIs of TSH, ATG, and ATPO in this study differed between sexes (P<0.05). The thyroid hormone RIs established herein were inconsistent with the manufacturer-provided values. Conclusion The RIs of thyroid hormones in the healthy population of Lanzhou were inconsistent with those in the manufacturer’s manual. Validated sex-specific values are required for diagnosing thyroid diseases.

Neoadjuvant therapy has been widely applied in the treatment of rectal cancer, which can shrink tumor size, lower tumor staging and improve the prognosis. It has been the standard preoperative treatment for patients with locally advanced rectal cancer. The efficacy of neoadjuvant therapy for rectal cancer patients varies between individuals, and the results of tumor regression are obviously different. Some patients with good tumor regression even achieve pathological complete response (pCR). Tumor regression is of great significance for the selection of surgical regimes and the determination of distal resection margin. However, few studies focus on tumor regression patterns. Controversies on the safe distance of distal resection margin after neoadjuvant treatment still exist. Therefore, based on the current research progress, this review summarized the main tumor regression patterns after neoadjuvant therapy for rectal cancer, and classified them into three types: tumor shrinkage, tumor fragmentation, and mucin pool formation. And macroscopic regression and microscopic regression of tumors were compared to describe the phenomenon of non-synchronous regression. Then, the safety of non-surgical treatment for patients with clinical complete response (cCR) was analyzed to elaborate the necessity of surgical treatment. Finally, the review studied the safe surgical resection range to explore the safe distance of distal resection margin.

This study aims to provide evidence for clinical practice by systematically reviewing the efficacy and safety of Gusongbao preparation in the treatment of primary osteoporosis(POP). The relevant papers were retrieved from four Chinese academic journal databases and four English academic journal databases(from inception to May 31, 2022). The randomized controlled trial(RCT) of Gusongbao preparation in the treatment of POP was included after screening according to the inclusion and exclusion criteria. The quality of articles was evaluated using risk assessment tools, and the extracted data were subjected to Meta-analysis in RevMan 5.3. A total of 657 articles were retrieved, in which 15 articles were included in this study, which involved 16 RCTs. A total of 3 292 patients(1 071 in the observation group and 2 221 in the control group) were included in this study. In the treatment of POP, Gusongbao preparation+conventional treatment was superior to conventional treatment alone in terms of increasing lumbar spine(L2-L4) bone mineral density(MD=0.03, 95%CI[0.02, 0.04], P<0.000 01) and femoral neck bone mineral density, reducing low back pain(MD=-1.69, 95%CI[-2.46,-0.92], P<0.000 1) and improving clinical efficacy(RR=1.36, 95%CI[1.21, 1.53], P<0.000 01). Gusongbao preparation was comparable to similar Chinese patent medicines in terms of improving clinical efficacy(RR=0.95, 95%CI[0.86, 1.04], P=0.23). Gusongbao preparation was inferior to similar Chinese patent medicines in reducing traditional Chinese medicine syndrome scores(MD=1.08, 95%CI[0.44, 1.71], P=0.000 9) and improving Chinese medicine syndrome efficacy(RR=0.89, 95%CI[0.83, 0.95], P=0.000 4). The incidence of adverse reactions of Gusongbao preparation alone or combined with conventio-nal treatment was comparable to that of similar Chinese patent medicines(RR=0.98, 95%CI[0.57, 1.69], P=0.94) or conventio-nal treatment(RR=0.73, 95%CI[0.38, 1.42], P=0.35), and the adverse reactions were mainly gastrointestinal discomforts. According to the available data, Gusongbao preparation combined with conventional treatment is more effective than conventional treatment alone in increasing lumbar spine(L2-L4) bone mineral density and femoral neck bone mineral density, reducing low back pain, and improving clinical efficacy. The adverse reactions of Gusongbao preparation were mainly gastrointestinal discomforts, which were mild.
