OBJECTIVETo observe the therapeutic effect of Wenshen Huatan Recipe (WHR) on patients with early or middle stage chronic renal insufficiency (CRI) and investigate the clinical validity of applying sputum and blood stasis theory in treating CRI.

METHODSSixty CRI patients were selected and randomly assigned to the treated group (n = 32) and the control group (n = 28), all received conventional and symptomatic treatment, but those in the treated group were given WHR additionally. Two months were taken as one treatment course and the study lasted for 3 treatment courses. Total effective rate was assessed at the end of the 2nd and 6th month, changes of clinical symptom scores of TCM, and levels of blood urea nitrogen (BUN) and serum creatinine (SCr) in the two groups were observed as well.

RESULTSThe total effective rate of the 2nd and 6th month was 68.8% and 75.0% respectively in the treated group and 42.9% and 35.7% in the control group respectively, the difference between the two groups was significant (P < 0.05). Symptoms were improving along with the increasing medication time, and the improvement between the two groups was significant (P<0.01). Levels of SCr and BUN were significantly lowered in the treated group after 2-month and 6-month treatment (P < 0.05, P < 0.01).

CONCLUSIONWHR can significantly improve the clinical effect of treatment on CRI during early-middle stage, suggesting that CRI could be treated based on sputum and blood stasis theory with definite clinical efficacy.

OBJECTIVETo evaluate the treatment effect of the two surgical methods for upper eyelid retraction with thyroid associated-ophthalmopathy.

METHODSTwenty-two patients (32 eyes) with inactive thyroid associated-ophthalmopathy were divided into 2 groups (11 for each group) randomly. 11 patients (18 eyes) in the group A were treated by central tenotomy of levator aponeurosis. Another 11 patients (14 eyes) in the group B were treated by lengthening of Mullers' muscle combined with levator muscle. The treatment effect was investigated in 6-month follow-up study.

RESULTSAll of the patients were improved with the two surgical methods, which there was very significant difference before and after the treatments (P < 0.01), but not between the two surgical methods (P > 0.05) by statistical analysis. There was recurrent retracting in 4 patients (6 eyes) of group A and in 1 patient (1 eye) of group B, which there was significant difference between the two groups (P < 0.05) by Chi-square test. None of the patients was overcorrected.

CONCLUSIONSThe two methods are both effective and safe in correcting upper eyelid retraction. The rate of recurrent retracting is lower in lengthening of Mullers' muscle combined with levator muscle than that in central tenotomy of levator aponeurosis.

OBJECTIVETo study the clinical effectiveness of Wenshen Huatan Recipe (WHR) in treating early-middle stage chronic renal insufficiency (CRI) of Pi-Shen yang deficiency syndrome (PSYDS).

METHODSNinety early-middle stage CRI patients of PSYDS were recruited and randomly assigned to the treated group (60 cases) and the control group (30 cases) in the ratio of 2:1. All patients received conventional and symptomatic treatment, but those in the treated group received WHR additionally. The observation was lasted for six months. The total efficacy, the Chinese medicine syndrome integral, and indices of the renal functions [including serum creatinine (SCr), blood urea nitrogen (BUN), creatinine clearance (CCr), serum cystatin C (Cys-C)], blood lipids [total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C)], as well as adverse reactions were observed before and after treatment.

RESULTSAfter six months of treatment, the total effective rate in treated group was 70.0% (42/60), which was obviously higher than that in the control group [43.3% (13/30), P < 0.05]. The Chinese medicine symptoms in the treated group were obviously improved, showing statistical difference between the two groups (P < 0.01). Better effects in lowering SCr, BUN, Cys-C, and LDL-C and increasing CCr were obtained in the treated group than in the control group (P < 0.05).

CONCLUSIONWHR could postpone the progression of CRI, improve the lipid metabolism, indicating certain therapeutic efficacy could be obtained in treating early-middle stage CRI from sputum theory.

Background and purpose:It has been demonstrated that radical prostatectomy for patients with oligometastatic prostate cancer may contribute to improving local control of prostate cancer and overall survival by several retrospective studies. Perioperative complications play an important role in determining whether radical prostatectomy is appropriate for patients with oligometastatic prostate cancer. This study aimed to discuss the recurrence rate and the sever-ity of perioperative complications, and the primary curative effect of radical prostatectomy on oligometastatic prostate can-cer patients.Methods:A total number of 247 patients who received radical prostatectomy were recruited in the study from Jul. 2015 to Jan. 2016, including 25 patients with oligometastatic prostate cancer and 222 patients with localized prostate cancer. Patients with perioperative complications in both groups were graded with the Clavien-Dindo grading system. The proportion of PSA decline and the rates and severity of perioperative complications were analyzed in both groups.Results:The cases of prostate specific antigen (PSA) decline in the oligometastatic group were 21 (84.0%), lower than the localized group with 212 cases (95.5%). There were 6 cases (24.0%) with postoperative complications in the oligometastatic group, including serious complications (Ⅲ or above) 1 case (4.0%), and 49 cases (22.1%) with postoperative complications in the localized group, including serious complications (Ⅲ or above) 7 cases (3.2%). The differences between the groups reached no statistical significance (P>0.05).Conclusion:Radical prostatectomy for patients with oligometastatic prostate cancer could be safe, effective, and appropriate, the risk of perioperative complications should not be one of the limiting factors.

OBJECTIVETo observe the therapeutic effect of Yishen Qingre Huashi Recipe (YQHR) in treating proteinuria of chronic glomerular disease patients with Pi-Shen deficiency complicated damp-heat syndrome (PSDCDHS).

METHODSTotally 121 stage 1 -2 primary chronic glomerular disease patients with PSDCDHS were randomly assigned to the treated group (85 cases) and the control group (36 cases) according to 2:1. All patients received conventional and symptomatic treatment. Patients in the treated group took YQHR additionally, while those in the control group took Losartan Potassium Tablet (50 mg each time, once per day) additionally. The therapeutic course for all was 6 months. Changes of 24 h urine protein, blood urea nitrogen (BUN), serum creatinine(SCr), and estimated glomerular filtration rate (eGFR) were observed at different time points. And the difference in therapeutic effects were compared between the two groups.

RESULTSCompared with the control group after 6 months of treatment, 24 h urine protein obviously decreased in the treated group (P <0. 05). There was no statistical difference in SCr, BUN, or eGFR between the two groups after 6 months of treatment (P >0. 05). The total effective rate after 2, 4, and 6 months of treatment in the treated group was 77. 6% (66/85 cases), 82. 4% (70/85 cases), and 89. 4% (76/85 cases), respectively. They were 47. 2% (17/36 cases), 55. 6% (20/36 cases), and 61. 1% (22/36 cases) in the control group, respectively. Compared with before treatment in the treated group, the total effective effect after 6 months of treatment was higher than that after 2 months of treatment (χ2=4. 28, P <0. 01). Compared with the control group at the same time points, the total effective rate in the treated group after 2, 4, and 6 months of treatment was higher (χ2=10. 87, 9. 53, 13.16, P <0. 01).

CONCLUSIONYQHR could significantly lower proteinuria in chronic glomerular disease patients with PSDCDHS, improve the clinical effect, thereby providing clinical evidence for treating chronic glomerular disease proteinuria from resolving dampness and clearing heat.

BACKGROUNDIn bone marrow transplant patients, the microenvironment in bone marrow is damaged after chemotherapy or radiotherapy. Subsequent to allogenic hematopoietic stem cell transplantation in patients with clinically successful engraftments, the source of mesenchymal stem cells (MSCs) remains controversial. To further verify the stimulatory effect of the simultaneous transplantation of cells from second donors on engraftment success for hematopoietic stem cell transplantation in support of donor MSCs engraftments, the aim of this study is to monitor the dynamics of the engraftment of bone marrow-derived MSCs in patients after transplantation with mismatched-sex hematopoietic stem and third-party cells.

METHODSIn this study, the hematopoietic stem cells from 32 clinical donors of different sexes that resulted in successful engraftments were selected for transplantation and were classified into three groups for research purposes: group A consisted of 14 cases of transplantation with bone marrow and recruited peripheral hematopoietic stem cell transplantation, group B contained 8 cases of simultaneous re-transfusion of MSCs from the second donor, and group C contained 10 cases of simultaneous re-transfusion of umbilical blood from the second donor. The bone marrow from 32 patients with successful engraftments of hematopoietic transplantation were selected and sub-cultured with MSCs. Flow cytometry (FCM) was used to measure the expression of surface antigens on MSCs. Denaturing high-performance liquid chromatography (DHPLC) in combination with polymerase chain reaction amplification of short tandem repeats (STRPCR) was used to measure the engraftment status of fifth-generation MSCs in patients. Fluorescence in situ hybridization (FISH) revealed the sex origin of the fifth-generation MSCs in 32 patients. Dynamic examinations were performed on patients receiving donor transplantations.

RESULTSThe progenies of fifth-generation MSCs were successfully cultured in 32 cases. The results of FCM demonstrated that the expression levels of CD14+ and CD45+ cells were lower than 0.04% in the fifth-generation MSCs. The analysis using DHPLC and FISH showed similar results. One patient from group B also received a temporary transplantation of MSCs from the donor. The MSCs in the remaining 31 patients all originated from the patients themselves.

CONCLUSIONSAfter transplantation, the MSCs present in patients originated from the host. In patients transplanted with MSCs from a second donor, the phenomenon of temporary chimerization of MSCs was observed.

OBJECTIVETo investigate the influence of intrauterine infection caused by lipopolysaccharide on Toll-like receptor 4 (TLR4) signaling pathway in fetal and neonatal rat lungs in order to explore immunomodulating activity of innate immunity responding to intrauterine infection and its effect on lung development.

METHODSOn day 17 of pregnancy, 30 pregnant Sprague-Dawley (SD) rats were randomly divided into two groups: LPS group and saline group. For LPS group, LPS (10 microl, 40 microg/ml) was intrauterine injected between every two embryonic sacs of the pregnant rats, while the rats in the control group were injected with the same volume of pyrogen-free saline. Lung tissues of fetal rats and corresponding placental tissues were collected on the embryonic day 18 (E18), E20, and E22. Neonatal lung tissues were also harvested on postnatal day 1 (P1), P3, and P7. Lung sections and placental tissues were stained with hematoxylin and eosin for histological examination. Reverse transcription quantitative polymerase chain reaction (RT-PCR) analysis was performed to test mRNA expression for TLR4, myeloid differentiation 88 (MyD88) and IL-1beta, while immunohistochemistry was used to evaluate TLR4 and MyD88 expression in lung tissues. All data were analyzed with one-way analysis of variance (ANOVA) and q test.

RESULTS(1) Placental hematoxylin-eosin staining showed a great number of neutrophils infiltration, obvious interstitial hyperplasia and narrow capillaries in placental tissues in the LPS group which indicated that intrauterine infection occurred. However, there were no obvious inflammatory cells in the control group. (2) On E18, E20 and E22, the lung of LPS group showed no obvious pathological changes, and there were no apparent neutrophils infiltrated in alveoli, then some structural changes appeared. On P7, we found that the number of alveoli decreased, space of alveoli was larger than ever, septa thickened, but without significant constructive disorder. (3) In the LPS group, the TLR4, MyD88 and IL-1beta mRNA levels increased compared with control group, higher than control group at E20 and E22 (P < 0.05), and peaked at E22. Then the expression levels of these substances decreased slowly. (4) The result of immunohistochemistry showed that in lung tissues of the two groups at E18, there was no remarkable positive staining of TLR4 and MyD88, which mainly expressed in cytoplasm of bronchiole and alveolar epithelial cells, then positive cells increased slowly.

CONCLUSION(1) For perinatal rat lungs, intrauterine LPS infusion can induce an increased expression levels of TLR4 and MyD88 to a certain extent, which then returned to normal level gradually. At the same time, lung tissues showed a mild pathological change and inflammatory reaction. We propose that innate immune system of fetal lungs controls the magnitude of the LPS-induced cytokine response during the perinatal period. (2) The findings confirmed that LPS-activated signaling transduction pathway was the MyD88-dependent pathway.

Ultrasound therapy is a new type of therapy technology, there are hyperthermia and high intensity focused ultrasound surgery (HIFUS). Compared with a single frequency system, mutiple frequency system has an additional function to combine power patterns of different frequencies. This function increases the availability of power patterns to treat tumors of various shapes and depths. Therefore, we have in this article proposed a system with the ability to drive ultrasonic phased arrays of multiple resonant frequencies for ultrasound hyperthermia and HIFUS. The results show that this system is able to (1) drive multi-element applicators or phased arrays of a single resonant frequency through the multichannel power amplifiers, (2) concurrently drive transducer with different resonant frequencies, (3) adjust the relative phase and output power of each channel for the scanning ultrasonic focus, and (4) operate each channel with good output stability.
