The connection between tendons and bones is called the tendon bone connection. With the continuous improvement of national sports awareness, excessive exercises and the related intensity are prone to damage the tendon bone connection. Tendon bone healing is a complex repair and healing process involving multiple factors, and good tendon bone healing is a prerequisite for its physiological function. The complexity of tendon bone structure also poses great challenges to the repair of tendon bone injuries. In recent years, researches have found that stem cells, growth factors, macrophages, and other factors are closely related to the healing process of tendon bone injuries, among which macrophages play an important role in the healing process. The authors reviewed relevant research literature in recent years and summarized the role of macrophages in tendon bone healing, in order to provide new ideas and directions for treatment strategies to promote tendon bone healing.

Schistosomiasis is a neglected zoonotic parasitic disease. Currently, praziquantel is the drug of choice for the treatment of schistosomiasis, and is the only effective chemical for treatment of schistosomiasis japonica. Since its introduction in the 1970s, praziquantel has been used for large-scale chemotherapy of schistosomiasis for over 40 years. However, there have been reports pertaining to the resistance to praziquantel in schistosomes. Therefore, development of novel antischistosomal agents as alternatives of praziquantel, is of great need. Histone deacetylases and histone acetyltransferases have been recently reported to play critical roles in the growth, development and reproduction of schistosomes, and are considered as potential drug targets for the treatment of schistosomiasis. This review summarizes the latest advances of histone deacetylase and histone acetyltransferase inhibitors in the research on antischistosomal drugs, so as to provide insights into research and development of novelantischistosomal agents.

Objective:To investigate the clinical efficacy of laparoscopic adrenalectomy and traditional open adrenalectomy for adrenal tumors in children.Methods:In Department of Pediatric Surgery, Fujian Provincial Maternity and Children′s Hospital from June 2008 to June 2016, the clinical data of 31 pediatric adrenal tumors was retrospectively analyzed.According to different surgical methods, they were divided into traditional open adrenalectomy group and laparoscopic adrenalectomy group.Bleeding loss, operation duration, incision length, abdominal drainage time, postoperative hospital stay, postoperative complications and recurrence were compared between the 2 groups.Results:There was no significant difference in age, sex, weight, and tumor size between the 2 groups (all P>0.05). The intraoperative bleeding loss was (18.06±4.86) mL for open adrenalectomy group and (15.20±4.48) mL for laparoscopic adrenalectomy group, and there existed no significant difference in the amount of bleeding between the 2 groups( T=-1.702, P>0.05). The operation duration was (137.44±19.32) min for open adrenalectomy group versus (134.80±6.21) min for laparoscopic adrenalectomy group, and there was no significant difference in operation duration between the 2 groups ( T=-0.504, P>0.05). The length of incision was (7.94±1.34) cm for open adrenalectomy group versus (3.44±0.21) cm for laparoscopic adrenalectomy group, the length of incision in laparoscopic group was shorter than that in open adrenalectomy group.There was significant difference in the length of incision between the 2 groups ( T=-12.843, P<0.001). The hospitalization time was (9.63±2.55) d for open adrenalectomy group versus (7.20±1.37) d for laparoscopic adrenalectomy group, the hospitalization time in laparoscopic group was shorter than those in open adrenalectomy group.The difference of operation time between the 2 groups was statistically significant ( T=-3.261, P=0.003). The average indwelling time of abdominal drainage tube was(5.94±1.53) d for open adrenalectomy group versus (4.80±1.74) d for laparoscopic adrenalectomy group, with no significant difference in postoperative abdominal drainage time between the 2 groups( T=-1.938, P>0.05). There was 1 case of retroperitoneal hematoma in laparoscopic adrenalectomy group and 2 cases of complications in open adrenalectomy group.There was no significant difference in the incidence of complications between the 2 groups ( P=1.000). There were 3 cases of distant metastasis and 1 case of recurrence in laparoscopic group, and 2 cases of distant metastasis and 1 case of recurrence in open adrenalectomy group.There was no significant difference in recurrence between the 2 groups ( P=1.000). Conclusions:Compared with open adrenalectomy surgery, laparoscopic adrenalectomy in children has various advantages, including beautiful incision, less trauma and fast recovery.However, it is necessary to select the appropriate cases.

OBJECTIVE: To investigate the expression of DNMT3b in human bladder cancer tissues and its correlation with postoperative survival of patients with bladder cancer. METHODS: Thirty-eight pairs of surgically resected human bladder cancer tissues and adjacent bladder tissues were detected by immunohistochemistry for DNMT3b expression, and the correlations of DNMT3b expression level were analyzed with the patients'age, gender, pathological grade, tumor size, T stage, lymph node metastasis and TNM stages. Kaplan-Meier survival analysis was performed to assess the effect of DNMT3b expression on survival outcomes of the patients. RESULTS: High DNMT3b protein expression was detected in 63.16% of the bladder cancer tissues and in 13.16% of the adjacent tissues ( < 0.05). The expression level of DNMT3b was associated with the pathological grade (=0.002), tumor size ( < 0.001), T stage ( < 0.001), lymphatic metastasis (=0.039) and TNM stage ( < 0.001), but not with gender or age of the patients. Multivariate logistic regression analysis showed that the protein expression level of DNMT3b was correlated with tumor size (=0.008) and TNM grades of the tumor (=0.042). Kaplan-Meier analysis showed that the patients with a high DNMT3b expression had a significantly shorter overall survival than those with a low DNMT3b expression (=0.021). CONCLUSIONS DNMT3b overexpression in bladder cancer is closely related to such clinicopathological factors as pathological grade, tumor size, T stage, lymphatic metastasis, and TNM stage and a shorter overall survival of the patients, suggesting the potential value of DNMT3b as a prognostic marker and a new therapeutic target for bladder cancer.

Objective: To investigate the difference in the clinical efficacy by thoracoscopy or thoracotomy for treating esophageal atresia. Methods: Thirty-one cases of type-Ⅲ esophageal atresia undergoing surgical treatment from February 2015 to May 2018 at the Department of Pediatric Surgery of Fujian Provincial Maternity and Children′s Hospital were included, and according to the different surgical methods they were divided into thoracoscopic group (15 cases) and thoracotomy group (16 cases). The operation duration, blood loss, postoperative chest drainage time, posto-perative hospital stay and postoperative complications were analyzed between 2 groups. Results: The mean time of operation was (181.33±13.86) min in the thoracoscopic surgery group and (139.06±10.98) min in the thoracotomy group, the thoracoscopic group had longer operation duration than thoracotomy group, and there was a significant difference in operation duration between two groups (t=9.44, P=0.000); mean blood loss was (3.07±0.96) mL in the thoracoscopic surgery group and (5.06±1.12) mL in the thoracotomy group, the thoracoscopic group had less amount of blood loss than thoracotomy group, and there was a significant difference in blood loss between two groups(t=-5.29, P=0.000); mean postoperative chest drainage time was(11.67±1.34) d in the thoracoscopic group and (12.25±1.06) d in the thoracotomy group, and there was no significant difference in postoperative chest drainage time between two groups(t=-1.34, P=0.19); mean time of postoperative hospitalization time was(15.20±0.94) d in the thoracoscopic group and (16.00±0.96) d in the thoracotomy group, and there was a significant difference in the postoperative hospitalization time between two groups (t=-2.33, P=0.027); the anastomotic leak rates were 33.33% (5 cases) versus 25.00% (4 cases) with closed or open approaches, respectively; anastomotic stricture rates were 40.00%(6 cases) versus 31.25% (5 cases) with closed or open approaches, respectively.There was no significant difference in postoperative incidence of anastomotic fistula and anastomotic stenosis between two groups. Conclusions Compared with thoracotomy in the treatment of esophageal atresia, thoracoscopic approach has smaller incision and less bleeding, less chest deformity, short hospital stay postoperatively, so it is safe and effective.However, the surgeon must have experience in doing thoracoscopic operation.

Objective To analyze the clinical characteristics of pseudohypoparathyroidism ( PHP ) inpatients in our hospital from January 2008 to December 2017 and to gain a better understanding of this disorder. Methods 18 inpatients diagnosed as sporadic PHP in our hospital were analyzed retrospectively, as regarding the clinical manifestation, laboratory examination and imaging data. Results 18 inpatients were diagnosed sporadic PHP consisting of 12 males and 6 females, with 13 adults and 5 child participants respectively. The medium age of onset was 14 (6-57), and the average age at diagnosis was (24.9± 14.7) years old. Initial onset of symptoms reported were: 12 patients complained of tetany, 3 reported convulsions, 1 reported numbness, 1 reported dysnoesia, and 1 were asymptomatic. Among them: 3 patients were found to have short distal phalanx, 7 displayed a round face, and 3 out of 15 adults were less than 155 cm in height. 12 patients had a positive Trousseau sign, 1 had an ectopic calcification. 11 were found to have intercranial massive calcifications by head computed tomography. Serum calcium was reported at (1.58 ± 0.11) mmol/ L and parathyroid hormone was (359.5 ± 146.6) pg/ ml. 3 patients were discovered to have hypothyroidism, 2 had been misdiagnosed with epilepsy, and 1 with encephalitis. Conclusions Tetany and intracranial calcifications were the most common signs of PHP patients. A number of the PHP cases in this study lacked typical Albright's Hereditary Osteodystrophy ( AHO) appearance. The age of onset and or duration of the disease varied somewhat in the different patient populations. The heterogeneity nature of the clinical manifestations of PHP makes it difficult to diagnose. It is therefore important to make accurate differential diagnosis of PHP to avoid misdiagnosis of the condition.

Objective To investigate the structure and optical activity of flavonoid derivative:2-(3,4-dimethoxyphenyl)-4-oxo-4 H-chromen-3-yl acetate(4).Methods The absolute configuration was obtained by X-ray single crystal diffraction.The optical rotation of the compound was determined by the SGW ?R-1 automatic polarimeter.Results X-ray single crystal diffrac-tion showed that compound 4 belongs to the orthorhombic space group P212121with a=7.763(2)?A,b=13.930(4)?A and c=14.906(4),α= β= γ=90.00°,V =1611.91(8)?A3,Z=8.There is no hydrogen bonding between the molecules in this crystal state.The molecules maintain their stable arrangement in space by van der Waals forces.It can be seen from the single-crystal data that there is a 33.9(2)° torsion of the dimethoxy-substituted benzene ring in the compound 4 with respect to the 4 H-chromene skeleton,suggesting that there may exist optical activity.Further experimental results of the optical rotation proved that the compound has a L-rotatory,specific rotation[α]19.1D = -5.077°.Conclusion The results of the single crystal indicated that the benzene ring substituted with dimethoxy group in compound 4 has a 33.9(2)° torsion relative to the 4 H-chromene skeleton,which results in chirality and optical activity.This is the first report that non-flavonoid-glycoside has optical activity.

Objective To investigate the efficacy and safety,as well as surgical essentials of upper urinary tract calculi (calculi being≤2 cm in diameter) complicated with pre-surgical uncertain pyonephrosis through one-stage renal calculi removal by percutaneous nephrolithotomy and suction device.Methods Retrospective analysis was used to detect the thirty-three cases with upper urinary tract calculi complicated with pre-surgical uncertain pyonephrosis collected from August 2010 to March 2016 in Yellow River Sanmenxia Hospital Affiliated to Henan University of Science and Technology,all the cases in the group had no pre-surgical fever,no apparent infection by blood-urine routine test,different degrees of hydronephrosis and no indications of pyonephrosis confirmed by CT and color Doppler ultrasonography,no pre-surgical anti-infection cure,pyonephrosis was found during the operation.First of all,a suction device was used to suck pus through percutaneous renal channel,rinsing repeatedly with small amount of fluid until the sucked rinsing fluid was clear;then,the one-stage calculi was removed by percutaneous renal lithotripsy,and the pus was sent to be cultured during the surgery,and the cases were treated by postoperative intravenous anti-infection for seven to seventeen days.Operation condition,postoperative blood routine,temperature,calculi removal and other clinical recovery conditions should be carefully observed.Results All the 33 cases underwent the one-stage single channel percutaneous nephrolithotom,the surgery was successful,the operation lasted 28-59 minutes,with an average of 41 minutes per case.Within the first-week of operation,CT reexamination showed the stone-free rate was 90.9% (30/33),and three cases had residual stone,the maximum diameter was about 6mm;seven cases had high fever within 3 days after the surgery (21.2%),and the temperature in four cases was higher than 38.5℃(12.1%) and two cases had fever within 3-6 days after surgery (6.1%),the highest temperature reached 38.0℃,and no fever existed after 6 days.Compared with preoperative values,the postoperative blood routine indicated that the surgery-relevant hemoglobin has decreased to (6.16±5.21) g/L;three days after surgery,white blood cell count was (7.16±4.86) 109/L.There were no severe complications such as sepsis,septic shock,renal abscess,hemorrhage.All cases were followed up for 6 to 36 months and no secondary pyonephrosis or renal dysfunction occurred during that period.Conclusion The treatment of upper urinary tract calculi,complicated with pyonephrosis without pre-surgical fever through one-stage renal calculi removal by percutaneous nephrolithotomy and suction device is effective and safe,it can be used as the routine method in basic hospitals and more attention should be paid to the operation and renal pelvic pressure in order to avoid the occurrence of complication.

OBJECTIVETo detect potential mutation in a pedigree affected with congenital nephrogenic diabetes insipidus (NDI).

METHODSClinical data of a male patient affected with NDI was collected. Genomic DNA was extracted from peripheral blood samples from the patient and five family members. The whole coding region of the arginine vasopressin receptor 2 (AVPR2) gene was amplified by PCR and directly sequenced.

RESULTSThe patient presented polyuria and polydipsia postnatally. Computerized tomography revealed bilateral hydronephrosis and hydroureter. The patient was responsive to hydrochlorothiazide but not to desmopressin. DNA analysis identified a hemizygous missence mutation c.295 T>C in exon 2 of the AVPR2 gene in the proband. His mother and grandmother were both heterozygous for the same mutation.

CONCLUSIONThe congenital NDI in the patient was probably due to mutation of the AVPR2 gene.

Objective:To analyze effect on the CD154-CD40 signaling pathway and Th1/Th2 polariza-tion by deficient inducible co-stimulator ( ICOS)-ICOS ligand ( ICOSL) signaling in mice infected with Schistosoma japonicum. Methods:ICOSL knockout ( ICOSL-KO) mice and wild-type C57BL/6J mice were used as experimental Schistosomiasis model infected with Schistosoma japonicum. The expressions of CD154 and CD40 on splenocytes and on inflammatory cells around granulomatous infiltration of liver in mice infected with Schistosoma japonicum were analyzed by flow cytometry,immunohistochemical staining, respectively, on the day before infection (0 week) and at the end of 4, 7, 12, 16 and 20 weeks post-infection. The splenocytes of the mice were stimulated with soluble egg antigen( SEA) for 72 hours, then the concentrations of interferon gamma(IFN-γ) and interleukin-4 (IL-4) in the culture supernatants were measured by sandwich enzyme-linked immunosorbent assay ( ELISA) kits. The levels of SEA-specific an-tibodies of IgG and IgG1 and IgG2a were measured in the mice sera by ELISA. The granulomatous pa-thology in the mice liver was dynamically observed by hematoxylin and eosin ( HE ) staining. Results:Compared with the wild-type C57BL/6J mice, the expressions of CD154 on CD4 + T splenocytes [(18. 62 ± 4. 76)% vs. (27. 91 ± 3. 94)%, (22. 44 ± 4. 67)% vs. (40. 86 ± 5. 21)%, (25. 50 ± 6. 81)% vs. (43. 81 ± 8. 41)%, (20. 22 ± 5. 28)% vs. (40. 95 ± 7. 34)%, (17. 87 ± 4. 59)% vs. (33. 16 ± 6. 31)%, all P <0. 01] and of CD40 on CD19 + B splenocytes [(19. 43 ± 3. 26)% vs. (24.37 ±3.59)%, (23. 00 ± 4. 47)% vs. (31. 80 ± 5. 86)%, (24. 46 ± 5. 01)% vs. (35. 85 ± 5. 32)%, (23. 42 ± 4. 69)% vs. (33. 30 ± 6. 14)%, (22. 85 ± 3. 78)% vs. (30. 88 ± 5. 94)%, all P<0 . 05 ] in the ICOSL-KO mice significantly decreased at the end of 4 , 7 , 12 , 16 and 20 weeks post-infection. Moreover, the expressions of CD154[(0. 319 ± 0. 066) vs. (0. 488 ± 0. 086), (0. 389 ± 0. 067) vs.(0.596±0.082),(0.378±0.064) vs.(0.543±0.072),(0.348±0.069) vs.(0.523±0.076), all P<0. 01] and CD40[ (0. 398 ± 0. 066) vs. (0. 546 ± 0. 079), (0. 461 ± 0. 085) vs. (0. 618 ± 0. 076), (0. 453 ± 0. 087) vs. (0. 587 ± 0. 074), (0. 449 ± 0. 065) vs. (0. 565 ± 0. 082), all P <0 . 05 ] on inflammatory cells around granulomatous infiltration in liver from the ICOSL-KO mice were sig-nificantly lower than those of the wild-type C57 BL/6 J mice at the end of 7 , 12 , 16 and 20 weeks post-in-fection. The levels of IFN-γ of the ICOSL-KO mice were significantly higher than those of the wild-type C57BL/6J mice at the end of 4, 7, 12, 16 and 20 weeks post-infection (P <0. 05). However, the levels of IL-4 of the ICOSL-KO mice were significantly lower than those of the wild-type mice ( P <0. 05). Compared with the wild-type C57BL/6J mice, the levels of SEA-specific antibodies of IgG and IgG1 and IgG2a in the sera of the ICOSL-KO mice significantly decreased (P<0. 01). Moreover, The Th2 differentiation index of the ICOSL-KO mice was significantly lower than that of the wild-type mice in post-infection (P<0. 01). Also, the ratio of IgG1/IgG2a of the ICOSL-KO mice were significantly lower than that of the wild-type mice at the end of 7 , 12 and 16 weeks post-infection ( P<0 . 05 ) . And the vo-lume of liver egg granulomas of the ICOSL-KO mice was significantly smaller than that of the wild-type mice ( P <0 . 01 ) . Conclusion: These findings suggest that there is obvious down-regulation in the expressions of CD154 and CD40 and impairment of Th2 immune response in the ICOSL-KO mice infected with Schistosoma japonicum, accompanying with notedly reduced hepatic granulomatous pathology. The ICOS-ICOSL signaling has a regulatory effect on CD154-CD40 signaling pathway, and may play an impor-tant role in the hepatic egg granuloma formation of Schistosomiasis.
