RESUMEN
Objective:To explore the effective method for treatment of small and short penis after hypospadias surgery.Method:s From November 2017 to November 2018, 57 children aged 4 to 14[mean age(7.91±2.89)years] with hypospadias who met the diagnostic criteria of small penis were reexamined at the First Affiliated Hospital of Xin-xiang Medical University.They were randomly divided into the physical treatment group and the drug treatment group according to the order of visits, and the untreated patients were included in the control group.Among them, 21 patients in the physical treatment group were treated with penile rehabilitation therapy apparatus, supplemented by Salvia mil-tiorrhiza bath (30 minutes/time, once/day, 10 days), and 20 patients in the drug treatment group were treated with Testosterone cream topically (3 times/day, 10 days). Penile relaxation length, stretch length, transverse and longitudinal diameters of glans in 2 groups before and after the treatment were measured.The relevant indexes of 16 patients in the control group measured before and after 10 days and compared with those in the treatment group.Result:s (1)The penile relaxation length in the physical treatment group increased from (25.48±6.13) mm to (30.72±6.49) mm, the length of stretch increased from (34.90±7.71) mm to (41.08±8.43) mm, the transverse diameter of glans increased from (14.81±3.40) mm to (16.57±3.42) mm, and the longitudinal diameter increased from (13.94±3.15) mm to (15.82±3.52) mm, and the differences were statistically significant (all P<0.05). (2)The penile relaxation length in the drug treatment group increased from (21.07±4.26) mm to (31.32±4.72) mm, the length of stretch increased from (31.94±7.96) mm to (45.39±7.24) mm, the transverse diameter of glans increased from (13.38±1.77) mm to (16.64±2.10) mm, and the longitudinal diameter increased from (13.09±1.77) mm to (16.62±1.86) mm, and the differences were statistically significant (all P<0.05). (3)There was no significant difference in penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans before and after 10 days in the control group (all P>0.05). (4) Compared with the control group, the penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans in the physical treatment group increased significantly, and the differences of growth values between the two groups were statistically significant (all P<0.05). (5) Compared with the control group, the penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans in the drug treatment group also increased significantly, and the difference of growth values between the two groups were statistically significant (all P<0.05). (6) The growth of penile relaxation length, the length of stretch and transverse and longitudinal diameters in the drug treatment group were higher than those in the physical treatment group, and the difference of growth values were statistically significant (all P<0.05). Conclusions:Both the negative pressure suction method and topical application of Testosterone cream are effective in the treatment of small and short penis after hypospadias surgery.However, Testosterone cream is difficult to obtain, and the treatment of negative pressure suction is simple, noninvasive, painless and free of adverse reactions.
RESUMEN
Objective To explore the clinical effect of negative pressure suction combined with washing by Chinese herbal bath to treat small penis in obese children at school age.Methods The data of 60 obese cases with small penis at the First Affiliated Hospital of Xinxiang Medical University from June 2016 to September 2017 were retrospectively analyzed,the age ranged from 7 to 15 years old,and the average age was (11.1 ± 2.0) years old,the body mass index(BMI) was 19.2-30.5,and the average BMI was 24.5 ± 2.6.Treatment group received the penis treatment with negative pressure instrument suction supplemented by traditional Chinese medicine bath treatment,once a day,20 minutes each times,10 days asa course,a totally of 2 treatment courses.Other 46 cases of male children who came to our hospital in the same period for physical exam were selected as healthy control group,aged 8-14 years old [(11.2 ± 2.1) years],BMI:14.6-21.0,mean 18.1 ± 1.6,and the relaxation length and elongation of 20 days before and after the normal growth state of the penis in the control group were measured.The length and elongation of the penis in the treatment group were compared with those of the healthy control group before and after treatment.Results The length of penile relaxation in the treatment group increased to (3.76 ±0.61) cm in comparison with that before treatment (2.94 ± 0.52) cm,and the difference was statistically significant (t =-7.82,P ＜ 0.05);the penis elongation increased compared with that before treatment (4.29 ± 0.67) cm to (5.37 ± 0.82) cm,and the difference was statistically significant (t =-7.91,P ＜ 0.05).The initial relaxation length of the control group was (3.96 ± 0.65) cm,(4.07 ± 0.65) cm 20 days after natural growth,the difference was not statistically significant (t =-0.82,P ＞ 0.05),the initial stretch length was (5.96 ± 0.92) cm,(6.03 ± 0.90) cm natural growth after 20 days,and the difference was not statistically significant (t =-0.37,P ＞ 0.05).Before and after treatment,the length of penis relaxation and elongation were significantly increased,but they didn't reach the normal level at the same age.Conclusions Negative pressure suction supplemented with Chinese herbal medicine bath has a significant effect on treating obese children with small penis.
RESUMEN
<p><b>OBJECTIVE</b>To explore the effects of electroacupuncture (EA) on behavioral function and synaptic plasticity in hippocampal CA3 area in rats with chronic stress depression.</p><p><b>METHODS</b>According to the random number table method, 144 SD male rats were assigned into a blank group, a model group, an EA group and a fluoxetine group, then each group was divided into a 7 d subgroup, a 14 d subgroup and a 21 d subgroup, 12 rats in each subgroup. The chronic mild unpredictable stress stimulus combined with lonely breeding were applied to establish the depression model of rats, which was performed simultaneously with intervention treatment. The rats in the EA group were treated with EA (dilatational wave) at "Shenting" (GV 24) and "Baihui" (GV 20), while the rats in fluoxetine group were treated with intragastric administration of fluoxetine, once daily. With open-field test, sugar consumption experiment and transmission electron microscope, the changes of behavior and neuronal synapse inhippocampal CA3 area were observed.</p><p><b>RESULTS</b>On 7 d, 14 d and 21 d, compared with the blank group, the open-field test score, sugar consumption and body mass were significantly lower in the model group (all<0.01); compared with the model group, the open-field test score, sugar consumption and body mass were significantly higher in the EA group and the fluoxetine group on 14 d and 21 d (<0.01,<0.05). On 14 d and 21 d, compared with the blank group, the synapse in hippocampal CA3 area was significantly lower in the model group (both<0.01); compared with the model group, the synapse in hippocampal CA3 area was significantly higher in the EA group and the fluoxetine group (<0.01,<0.05). The neurons cells in hippocampal CA3 area in the model group showed pyknosis and deformation from 7 d with fusion structure and unclear boundary of synapse, which were significantly improved on 21 d; the neurons cells in hippocampal CA3 area in the EA group and the fluoxetine group were significantly improved from 14 d and restored to normal level on 21 d, in addition, the structure of synapse restored to normal level.</p><p><b>CONCLUSIONS</b>EA is involved in the regulation of synaptic plasticity in hippocampal CA3 area, and promotes the recovery of depression symptoms.</p>
