Objective To investigate the feasibility and characteristic of tissue engineered testicular prosthesis with highdensity polyethylene(HDPE，trade name: Medpor) and polyglycolic acid(PGA). Methods The chondrocytes were isolated from the swine articular.The PGA scaffold was incorporated with medpor which semidiameters were 6mmand 4mm respectively.Then, the chondrocytes (5×10 7/ml) were seeded onto Medpor-PGA scaffold and cultured for 2 weeks. The ten BALB／C mice were divided into two groups randomly(n=5). In the experimental group, the cell-scaffold construct was implanted into subcutaneous pockets on the back of nude mice. In the control group, the Medpor-PGA scaffold was implanted. The mice of two groups were sacrificed to harvest the newly formed cartilage prosthesis after 8 weeks. Macroscopy, histology and immunohistochemistry observations were made. Results The gross observation showed that on changes were in shape and at size, the color and elasticity were similar to that of normal cartilage and that the cartilage integrated with Medpor in the experimental group; no cartilage formed and fiberlike tissue was found in the control group. HE staining showed that many mature cartilage lacuna formed without blood vessel and some PGA did not degradated completely. Toluidine blue staining showed extracellular matrix had metachromia. Safranin O-fast green staining showed that many proteoglycan deposited and collagen type Ⅱ expression was bly positive. In the control group, Medpor was encapsulated by fiber tissue with rich blood vessel. Conclusion The newly formed complex of Medpor-PGA and cells was very similar to testicle in gross view and to normal cartilage in histology. This pilot technique of creating testicular prosthesis by incorporating tissue-engineered cartilage with Medpor demonstrated success.
From October 1985 to October 1988, fourty-nine impalpable testis in 39 patients were treated. The ages of the patients ranged from lyear 10 months to 11 years. There were fixed testis into scrotum (in 24 cases), superficial layer of aponeurosis of musculus obliquus externus abdominis (in 4 cases), autotransplantation (in 7 cases), and testectomy (in 11 cases). No testis in 3 cases were conformed in exploration. The author suggestes it necessary to do exploration early in impalpable testis of children to obtain good physiologic function of testis.
ObjectiveTo explore the differences in ultrasonographic features of testicular teratoma and yolk sac tumor (YST) in children.MethodsA total of 44 patients were selected, including 30 with testicular teratoma and 14 with YST, whose diagnoses were confirmed by surgery and pathology in West China Second University Hospital, Sichuan University from January 2015 to June 2019. The differences in ultrasonograhic characteristics of the two groups were compared, such as the size, location, internal echo, composition, and blood supply of the tumors.ResultsThe mean value of maximum diameters of testicular teratomas was (24.25±12.13) mm and that of YSTs was (29.71±18.75) mm, with no statistically significant difference between the two groups (F=0.531, P=0.383). In terms of the compositions of the tumors, cystic-solid lesions were the most common in testicular teratomas (17/30), followed by solid lesions (8/30) and cystic lesions (5/30); while solid lesions were the most common in YSTs (12/14), followed by cystic-solid lesions, and cystic lesions did not appear. The difference in the compositions of tumors was statistically significant between children’s testicular teratomas and YSTs (P=0.001), especially in the proportion of solid lesions. In terms of Adler grade of blood flow, there were 9 cases of Adler 0, 10 cases of Adler 1, 10 cases of Adler 2, and 1 case of Adler 3 in testicular teratomas, while there were 0 case of Adler 0, 1 case of Adler 1, 4 cases of Adler 2, and 9 cases of Adler 3 in YSTs. The difference in the blood supply was statistically significant between children’s testicular teratomas and YSTs (P<0.001). Testicular teratomas tended less to behave as Adler 3, while Adler 3 was the most common in YSTs. There was no statistically significant difference in other ultrasonic features, like the location, internal echo, or the existence of calcification (P>0.05).ConclusionsUltrasound has a certain meaning for the differential diagnosis of testicular teratoma and YST in children. By comparing the solid component and the blood supply of the tumor, it is helpful for enhancing the diagnostic confidence of sonographer.

Methods We retrospectively analyzed the ultrasonographic features before and after treatment, and the clinical treatment results of 53 patients with epidemic parotitis accompanied by orchitis between October 2008 and December 2010. Results All patients had different level of increment in their parotid gland, submaxillay gland, testicle or epididymis. Most cases of the increment occurred to unilateral parotid gland and submaxillay gland on the same side, as well as unilateral testicle and unilateral epididymis. After clinical treatment for 15 to 20 days, parotid and testicular swelling and pain, and self-conscious symptoms disappeared. Forty patients returned to normal ultrasonic image, and the ultrasonic images of 13 other patients resumed normal basically. After being discharged, all patients were followed up and ultrasound observation was carried out which showed that 3 to 4 months or 4 to 6 months later, all ultrasonic images were normal. Conclusion Ultrasound dynamic observations before and after treatment have important values to the diagnosis and prognosis of epidemic parotitis accompanied by orchitis.
To explore the effect of burying testis in inguinal pocket on spermatogenesis. Methods Sixty New Zealand rabbits of 6-8 months old included 36 males and 24 females, weighing 2.5-2.7 kg. The male rabbits were randomly divided into the experimental group (n=18)and the control group (n=18). The model of repairing skin defect of scrotum were establ ished by burying testes in inguinal region subcutaneously in the experimental group. The rabbits were not treated in the control group. The sperms were collected and the surface temperature of testis was measured in both groups after 8 weeks. Testes biopsies were harvested from 6 rabbits of 2 groups randomly respectively. The apoptosis of spermatogeniccells was detected with TUNEL. The other 12 male rabbits in two groups were fed respectively with female rabbits to observe the fertil ity. Results The semen density and the spermid activity ratio were (237.3 ± 39.7) × 109/L and 76.9% ± 3.8% in the control group, and were (4.7 ± 2.7) × 109/L and 0 in the experimental group respectively; showing statistically significant difference between two groups (P lt; 0.05). The average superficial temperature of testes was (38.02 ± 0.36)℃ in the experimental group and (36.15 ± 0.64) in the control group (P lt; 0.05). TUNEL results showed: The spermatogenic epithel ium became thin and obvious apoptotic spermatogenic cells were found in experimental group; the spermatogenic epithel ium was normal and few apoptotic spermatogenic cells were found in the control group. The apoptotic index (AI) was 89.69% ± 3.76% in the experimental group and 7.73% ± 4.95% in the control group (P lt; 0.05). The Pairing results showed that the female rabbits pairing with male rabbits of the experimental group were all not pregnant, and those of the control group were all pregnant (P lt; 0.05). Conclusion As the same as the scrotum was reconstructed with skin flaps, it will induce the rabbit infertil ity that the testes were buried in inguinal region subcutaneously to repair defect of scrotum skin. The main reason is the excessive apoptosis of spermatogenic cell by the high testes environmental temperature.
OBJECTIVE: To investigate the injury on isolated testes induced by ischemia/reperfusion(I/R), and the protective effect of Yisheng injection on the injury. METHODS: Twenty-six isolated cadaver testes contributed by 13 persons were preserved with 4 degrees C 250 ml hypertonic citrate alloxuric (HCA) solution and then reperfused with 37 degrees C 500 ml HCA. Solution of experimental group contained 500 micrograms/ml Yisheng injection. In simple cold preservation test, involving in 8 experimental and 8 control testes, a series of time points (6, 12, 18, 24, 36, 48, 60, 72 hours) were set to harvest. 10 testes (1 testis respectively on 6, 12, 18, 24 and 36 hours in experimental and control groups) were reperfused with 37 degrees C HCA for 6 and 12 hours. Histological and histochemical changes were observed. RESULTS: In the experimental testes, 4 degrees C cold preservation in 24 hours could not induce obvious pathologic changes. After 24 hours, changes such as swelling, vacuolar degeneration or detachment of endothelial cells (ECs), separation between basement membrane and seminiferous epithelium, mal-alignment of spermatogenous cell and edema of mesenchyme could be observed. In the testes preserved for 12 hours, the activity of lactic dehydrogenase(LDH) and succinic dehydrogenase (SDH) increased, then fallen after 24 hours. The activity of Nitric oxide synthetase(NOS) decreased after 18 hours. All changes were more obvious after following 37 degrees C reperfusion. In the control testes, swelling and vacuolar degeneration of ECs occurred on 12 hours cold preservation, and injury was worse along with the prolongation of cold preservation time. Pathologic changes of ECs, seminiferous epithelium and mesenchyme were serious after 37 degrees C reperfusion. CONCLUSION: 4 degrees C cold preservation in 24 hours can only cause mild ECs’ injury, and obvious abnormal testes’ histological profile can be observed beyond 24 hours. 37 degrees C reperfusion will make injury worse. Yisheng injection can keep isolated testes histologic structure well in 24 hours cold preservation, and it has protective effect on I/R injury.
