RESUMO
Osteoporosis is an important cause of bone weakness and susceptibility to fractures. Anti-osteoporosis drugs of Western medicine cannot reverse its progression, and can only reduce the loss of bone density; long-term use of them is accompanied by certain adverse reactions. Traditional Chinese medicine focuses on syndrome differentiation and holistic approach, which can make up for the shortcomings of Western medicine’s treatment. The mammalian target of rapamycin (mTOR) signaling pathway is involved in the growth, proliferation, and differentiation of bone cells, and is closely related to the occurrence and development of osteoporosis. In recent years, various traditional Chinese medicine monomers (such as flavonoids, polysaccharides, alkaloids, etc.) and traditional Chinese medicine formulas (such as Bushen huoxue decoction, Liuwei dihuang pills, Erzhi pills, etc.) have been proven to promote bone formation, inhibit bone resorption, enhance bone cell autophagy, and delay the progression of osteoporosis by regulating the mTOR signaling pathway. Therefore, the article summarizes the traditional Chinese medicine monomer and formula that intervene in the mTOR signaling pathway for the treatment of osteoporosis, in order to provide medication ideas for the traditional Chinese medicine treatment of osteoporosis.
RESUMO
Objective:To investigate the effects of laparoscopic surgery versus open surgery on acute appendicitis in children. Methods:We retrospectively analyzed the data of 50 children with acute appendicitis who underwent surgery in Zhoushan Women and Children Hospital from December 2016 to December 2019. They were randomly divided into observation ( n = 27) and control ( n = 23) groups. The observation group underwent three-port laparoscopy. The control group underwent open surgery. Operation-related indicators, postoperative recovery, parental satisfaction, and complications were compared between the two groups. Results:Operative time was significantly longer in the observation group than in the control group [(56.57 ± 5.35) minutes vs. (40.23 ± 6.31) minutes, t = 9.78, P < 0.001). Intraoperative blood loss was significantly less in the observation group than in the control group [(10.11 ± 2.36) mL vs. (18.36 ± 3.21) mL, t = 10.45, P < 0.001]. Duration of pain was significantly shorter in the observation group than in the control group [(1.23 ± 0.23) days vs. (2.98 ± 0.87) days, t = 10.06, P < 0.001). Time to postoperative exhaust was significantly shorter in the observation group than in the control group [(21.39 ± 4.35) minutes vs. (39.88 ±5.39) minutes, t = 13.35, P < 0.001]. Time to defection was significantly shorter in the observation group than in the control group [(50.12 ± 3.35) minutes vs. (61.23 ± 4.21) minutes, t = 10.33, P < 0.001]. Time to first diet was significantly shorter in the observation group than in the control group [(13.25 ± 2.56) hours vs. (19.96 ± 2.67) hours, t = 9.07, P < 0.001]. Length of hospital stay in the observation group was significantly shorter in the observation group than in the control group [(4.13 ± 1.12) days vs. (7.98 ± 1.96) days, t = 8.53, P < 0.001). Parental satisfaction was significantly higher in the observation group than in the control group [96.30% vs. 47.83%, χ2 = 13.360, P < 0.001]. The incidence of complications was significantly lower in the observation group than in the control group [7.41% vs. 52.17%, χ2 = 10.58, P < 0.001]. Conclusion:Laparoscopic surgery is superior and safer to open surgery in the treatment of acute appendicitis in children.

RESUMO
Objective To compare the clinical value of XELOX and FOLFOX6 in the treatment of elderly patients with colorectal cancer. Methods Clinical data of 68 elderly patients(aged>60 years)with colorectal cancer were retrospectively analyzed.The patients were divided into XELOX group(n =32)and FOLFOX6 group(n =36) according to the chemotherapy regimen.The response evaluation criteria in solid tumors,progression free survival, 2 -year mortality,chemotherapy related adverse reactions and health related quality of life in the two groups were compared.Results Compared with the FOLFOX6 group,the neurotoxicity incidence in the XELOX group was signifi-cantly lower (3.13% vs.22.22%,χ2 =5.380,P =0.020).The neutrophils reduced incidence was significantly lower(9.38% vs.30.56%,χ2 =4.649,P =0.039).The hand foot syndrome complications significantly increased (34.38% vs.8.33%,χ2 =7.027,P =0.008).There was no significant difference in the incidence of nausea,vomi-ting,diarrhea,oral mucosal ulcer,thrombocytopenia and elevation of transaminase in the two groups(χ2 =0.001, 0.000,0.008,2.102,1.071,1.851,all P >0.05).The quality of health related quality of life was significantly higher in the XELOX group than in the FOLFOX6 group at 6 months after the operation[(67.94 ±12.49)points vs. (57.39 ±13.59)points,t =3.198,P =0.015].There were no significant differences in the curative effect grade at 6 months after the operation,2 -year mortality rate and progression free survival time between the two groups(χ2 =0.949,0.008,t =0.573,all P >0.05).Conclusion Although XELOX increases the incidence of hand foot syn-drome in elderly patients with colorectal cancer,but it significantly reduces the incidence of neurotoxicity and neutro-phil,and improves the quality of life of patients after surgery.
RESUMO
National traditional Chinese medicine (TCM) master professor Ban Xiuwen had rich experiences on treatment of gynecological diseases with unique insights on diagnosis and treatment for disorders of menstruation, leukorrhea, pregnancy and delivery. FemaleYin-Wei, which was a gynecological disorder, was recorded in the book ofHuang-Di Nei-Jing. However, due to different reasons, TCM study on femaleYin-Wei was far less than the study on male impotence. ProfessorBan Xiuwen had specific considerations for this disease on the book of Treatment of Miscellaneous Gynecological Diseases. In his understanding, femaleYin-Wei was due to four aspects, which were the innate deficiency, yang deficiency and coldness of the uterus; seven emotion damage, liver-qi soothing disorder; spleen-stomach deficiency,qi-blood deficiency; and phlegm-dampness stasis,qi stagnation. Through the analysis and study on case records of femaleYin-Wei treatment by national TCM master professorBan Xiuwen, this article briefly elaborated professorBan Xiuwen’s understandings on femaleYin-Wei treatment from etiology, pathogenesis, treatment according to syndrome differentiation, and clinical experiences. Two femaleYin-Wei cases treated by professorBan Xiuwen were given as examples in order to analyze the etiology, pathogenesis, treatment according to syndrome differentiation and treatment experiences in details. The therapeutic effects of both cases were obvious, which were also important study documents.
RESUMO
Objective To compare the perioperative outcomes of robot-assisted partial nephrectomy (RAPN) with transperitoneal laparoscopic partial nephrectomy (LPN).Methods From July 2009 to March 2013,114 patients were treated in our hospital due to renal carcinoma,including RAPN in 45 patients and LPN in 69 patients.Their data were retrospectively reviewed.Clinical and pathological variables,R.E.N.A.L nephrometry score,operation time (OT),warm ischemia time (WIT),estimated blood loss (EBL),drainage volume,the length of hospitalization,estimated glomerular filtration rate (eGFR) outcomes,and complications were analyzed.Results There were no significant differences between the RAPN and LPN group with respect to patient age,sex,tumor laterality,size,R.E.N.A.L nephrometry score,the rate of hilar tumor and preoperative eGFR (P>0.05).The median OT was shorter in the RAPN group than that in LPN group (165 min vs.196 min,P<0.05).The median WIT was shorter in the RAPN than that in LPN group (21 min vs.25 min,P<0.05).However,there were no significant differences in the postoperative eGFR and changing of eGFR within the 2 groups (P>0.05).The rate of transfusion was similar between the RAPN (2/45) and LPN (4/69) group (P=0.72).There was also no significant difference in EBL (P=0.16).The drainage volume was also similar within two groups (167 ml vs.163 ml,P=0.81).The length of hospitalization was more favorable in the RAPN group (6.5 d vs.8.0 d,P=0.01).In RAPN group,27 cases were clear-cell carcinoma,5 cases were papillary cell carcinoma,2 cases were chromophobe cell carcinoma and 1 1 cases were angioleiomyolipoma.In LPN group,45 cases were clear-cell carcinoma,9 cases were papillary cell carcinoma,3 cases were chromophobe cell carcinoma and 12 cases were angioleiomyolipoma.There was no difference of pathological types between LPN and RAPN groups (P>0.05).The rate of positive surgical margins was 0% (0/45) in RAPN group and 1.4% (1/69) in LPN group (P=0.69).The rates of complication requiring intervention (Clavien grade Ⅲ) were 2.2% (1/45) and 2.9% (2/69) in the RAPN and LPN group,respectively (P>0.05).Median follow up was 12 (4-36) months in the RAPN and 13 (5-34) months in the LPN group.No local recurrence or metastasis occurred in two groups.Conclusions Early comparative outcomes suggest that RAPN has a significant benefit over the LPN in terms of OT,WIT and hospital stay.Meanwhile,it offers equivalent prognosis and postoperative renal function preservation compared with LPN.
RESUMO
ObjectiveTo study the risk factors of renal artery pseudoaneurysm (RAP) following partial nephrectomy.MethodsOpen partial nephrectomy was performed on a total of 464 cases of renal cell cancer from July 2003 to May 2010. Five patients ( 1.1% ) had postoperative hemorrhage from RAP.The surgery technique of the open partial nephrectomy, the clinical presentation, imaging findings and treatment of RAP were reviewed. The anatomical characteristics of these five renal tumors on enhanced CT were quantified using the R.E.N.A.L. Nephrometry Score System.ResultsAll five cases were male, two had tumors on the left side and three on the right side. Median tumor size was 3.6 cm ( range from 2.5 to 5 cm; Radius score 1 - 2). Four tumors were exophytic of these, three had a major endophytic component (≥50%) deep in the parenchyma (Exophytic/endophytic score 2 ), one was entirely endophytic (score 3 ). The distance of all the tumors to the collecting system was ≤4 mm ( Nearness score 3 ). Four of the five tumors were across the polar line and/or renal axial midline ( Location score 3 ). The other tumor was located under the lower pole ( Location score 1 ) but close to the renal hilar. All patients presented with delayed gross haematuria and decreasing hemoglobin occurred on mean postoperative day 12 (3 -23 day). Four patients complained of flank pain, two of which had signs of hypovolemia requiring blood transfusion. The diagnosis was confirmed by the contrast medium-enhanced CT and selective angiography, and RAP was found most commonly arising from the segmental branch of renal artery. Superselective microcoil angioembolization was successfully performed in four cases, once in three cases and twice in the remaining case. The procedure failed in one patient and a nephrectomy was done. At a mean follow-up of 21 months (12 -30) , all patients had normal renal function without evidence of recurrence.ConclusionsRAP should be considered in all patients who had delayed hematuria after partial nephrectomy. A central, deep tumor and its relationship to the segmental branch of renal artery could be an important risk factor for this complication. Choosing the case properly for partial nephrectomy and suturing the transected vessels and the defect of parenchymal correctly could reduce occurrence of this serious complication. Early use of selective angioembolization could be a primary choice of treatment.

RESUMO
OBJECTIVE: To investigate the effects of Wenyang Huoxue Recipe (WRHXR), a compound traditional Chinese herbal medicine for warming yang and promoting blood flow, on the expression of angiopoietin mRNA in rats with chronic aristolochic acid nephropathy induced by Caulis Aristolochia Manshuriensis (CAM) decoction, and to explore the protection mechanism of WYHXR against kidney damage. METHODS: Twenty-eight male SD rats were randomly divided into normal control group, CAM group and WYHXR-treated group. Rats in the normal control group (n=8) and CAM group (n=10) were intragastrically administered with normal saline 10 ml/(kg.d) or CAM decoction 10 ml/(kg.d) respectively. Rats in the WYHXR-treated group (n=10) were intragastrically administered with WYHXR 30 g/(kg.d) and CAM decoction 10 ml/(kg.d). The expressions of Ang-l and Ang-2 mRNAs were detected by real-time reverse transcription polymerase chain reaction (RT-PCR) after 20-week treatment. RESULTS: Compared with the normal control group, the expression of Ang-l mRNA was significantly decreased, and the expression of Ang-2 mRNA was significantly increased in the CAM group (P0.05). Renal pathology showed that renal damage in WYHXR-treated group was significantly reduced as compared with the CAM group. CONCLUSION: WYHXR can up-regulate the expression of Ang-l mRNA, which may be its action mechanism in protecting the kidneys.
RESUMO
@#Objective To explore the degeneration of motor end plates (MEP) by observing the expression of calcitonin gene-relative peptide (CGRP) and acetylcholine esterase (AChE) in the MEP after different types of spinal cord injury. Methods 60 adult female Wistar rats were randomly assigned to 3 groups: sham group, completely transection group and contusion group. The content of AChE in the MEP was detected with Karnovsky-Roots staining and the expression of CGRP was then determined with immunohistochemistry. Results The content of both AChE and CGRP significantly decreased after either type of spinal cord injury. However, their activity gradually recovered to the normal level in the contusion group, but not in the transection group. Moreover, the changes of CGRP occurred earlier than those of AChE. Conclusion The motor end plate degenerates differently after different kinds of spinal cord injury in adult rat, CGRP and AChE are related to the degeneration of MEP.

RESUMO
@#Objective To explore the restoration of motor function and the expression of calcitonin gene-related peptide(CGRP)and acetylcholine esterase(AChE)in the anterior horn motoneurons after different types of spinal cord injury.Methods 60 adult female Wistar rats were randomly assigned to 3 groups:sham group,completely transection group and contusion group.Average combined scores(ACOS)were applied to assess the motor function at various time after the surgery.The content of AChE in the anterior horn of L2-L4 was detected with Karnovsky-Roots staining and the expression of CGRP was then determined with immunohistochemistry.Results The scores of ACOS were much higher in the contusion group than in the transection group at each time point examined.The content of both AChE and CGRP significantly decreased after either type of spinal cord injury.However,their activity gradually recovered to the normal level in the contusion group,but not in the transection group.Moreover,the changes of CGRP occurred earlier than those of AChE.Conclusion There is strong relationship between the motor function recovery and the functional state of anterior horn cells.CGRP or AChE may play an important role in the functional recovery of locomotion after spinal cord injury in rats.
RESUMO
@#ObjectiveTo evaluate the biocompatibility of a kind of scaffolding material,Injured Nerve Regenerated Materid(INRM), which play the roles of regeneration of nerve after traumatic brain injury.MethodsINRM scaffolding material were transplanted into cortex of rats after traumatic injury.The brain coronal sections were stained for Nissel, astrocyte and microglia at 1 week, 1 month, and 2 months after injury.ResultsThe presence of INRM did not alter patterns of astrocyte compared with the control group (detected with antibodies against GFAP) at any time point; but decreased the expression of microglias (detected with antibodies against OX42) compared with the control group.ConclusionThe biomaterial INRM is well suited as a biocompatible scaffold material for the repair of brain injury in the brain.
RESUMO
@#ObjectiveTo study the effect the chitosan tube combined with the bio active carrier system on inducing nerve axon regeneration of rats with spinal cord injury.Methods50 female Wister rats were characterized by the right spinal cord hemisections at the seventh and eighth thoracic segment to make the model of spinal cord hemisection. The chitosan tube serving as a regenerative loculus was implanted in the defect location of the experimental models.In the experimental group,the bio active carrier system was injected into the chitosan tube,while in control group injected nothing.The drua was sutured to restore cerebrospinal fluid circulation.Results6 months and 12 months after operation,the regenerative nerve axon had passed the defect area of spinal cord in the experiment group. According to WGA-HRP anterograde axonal tracing study, some TMB-positive axons were observed in the distal graft host interface,and came into the host environment. TEM-ultrastructure indicate some neonate synapse, myelinated nerve fibers.In the control group,few regenerative axon could be seen, there was no regenerative axon pass the middle of the tube.ConclusionsThe chitosan tube in which the bio active carrier system was injected can induce the spinal cord nerve axon regeneration.
