Varicocele is a common disease of the male reproductive system, and the pampiniform plexus in the spermatic cord manifests abnormal dilatation, extension, and circuity, which is a vasculopathy. In this article, we believe that the relevance of the essence chamber collaterals to the spermatic vein in terms of anatomical morphology and physiological function is high and that when pathogenic qi invades the essence chamber, the qi and collaterals of the essence chamber are out of harmony, the fluid collaterals are impassable, and the blood collaterals are obstrcuted, and the essence chamber collaterals are blockaded with several pathological products, and even intermingled phlegm and blood stasis in the blood collaterals and form vascular clusters, resulting in the formation and development of varicocele. Based on this, this article proposes the core treatment principle of healing, harmonizing, activating, and dredging the collaterals, with the basic treatment method of nourishing qi and harmonizing collaterals, activating blood collaterals, and dredging blood stasis to, respectively treat degree Ⅰ, Ⅱ, and Ⅲ varicocele, aiming to prevent the change of the varicocele, dredge the curvature of the varicocele, and dissipate the knots of the varicocele. The proposal of essence chamber collaterals is of great significance to understanding the common law and pathological aspects of the occurrence and development of essence collateral and vascular lesions from the perspective of integrated traditional Chinese and Western medicine.

The theory of "brain-heart-kidney-semen chamber" axis is proposed based on the basic theories of traditional Chinese medicine， the modern physiological characteristics of men's diseases， and clinical practice. According to this theory， dysfunctions of the brain， heart， kidney， and semen chamber are the core mechanisms for the occurrence of premature ejaculation， and the loss of control of the opening and closing of the seminal orifices due to the dysfunction of the semen chamber is the final link in the occurrence of premature ejaculation. The treatment of premature ejaculation based on the theory of "brain-heart-kidney-essence chamber" axis highlights the overall regulation of the Zang-fu organs involved in the disease， while focusing on the simultaneous treatment of the mind and body. By exploring the biological basis of the "brain-heart-kidney-essence chamber" axis and premature ejaculation， we propose that the biological basis of premature ejaculation and the axis is mainly related to the function decline of the local brain area， neuromodulation malfunction， central neurotransmitter imbalance， endocrine disorders， and enhanced sensory afferents of the penis. This study aims at providing a new approach for the prevention and treatment of premature ejaculation by traditional Chinese medicine and a scientific basis for the development of more effective therapeutic methods.

Male lower urinary tract symptoms is a collective term for a group of symptoms associated with lower urinary tract disorders characterized by frequent urination, urgent urination, and difficulty of urination, of which the common causes are benign prostatic hyperplasia or overactive bladder. With the aging of the global population, the incidence of male lower urinary tract symptoms is increasing year by year. Based on the theoretical connotation of " zang-fu extraordinary connection", the relationship between the lungs and the bladder, the spleen and the small intestine, and the kidneys and the sanjiao with the formation of male lower urinary tract symptoms is explained from three perspectives. It is believed that lung qi depression and closure, disturbance of qi transformation in bladder, and insufficient spleen transport occur, the small intestine is dysfunctional, kidney yang is exhausted, and obstruction of the sanjiao waterway are the basic pathogenesis of male lower urinary tract symptoms. It is emphasized that the location of the disease should be identified. If it is related to the lungs and the bladder, then the disease should be treated by lifting the pot to lift the lid and diffusing the lung qi to benefit the bladder with Wuling Powder plus perilla leaf and bitter apricot seed; if it is related to the spleen and the small intestines, then the disease should be treated by raising the clear and directing the turbid downward and improving the spleen qi in order to support the small intestines with Shenling Baizhu Powder; if it is related to the kidneys and the sanjiao, then the disease should be treated by seeking the yang within the yin and warming and tonifying the kidney qi in order to dredge up the sanjiao with Bawei Shenqi Pill. According to the patient's condition, treatment can be combined with acupuncture, exercise, and other therapies. This paper can provide reference for clinical treatment of male lower urinary tract symptoms.

Male infertility,a common condition in andrology,falls under the category of"no son"in traditional Chinese medicine(TCM).Unhealthy eating habits and excessive sexual activity,prevalent due to improved living standards,have contributed to the increasing incidence of male infertility.YE Tianshi proposed the theory of"maintaining with the sweet and restoring the body fluids",which emphasizes the importance of ample body fluid for the nourishment of the male essence chamber.Sufficient body fluid is crucial for normal sperm generation.In TCM,the primary pathogenesis of male infertility involves the loss of body fluids and insufficiency of yin essence.Sweet Chinese herbal medicinal is recommended as it nourishes yin,enriches essence,and replenishes male reproductive essence without producing phlegm and dampness.Therefore,when treating male infertility,attention should be given to the use of sweet Chinese herbal medicinal,adhering to the principle of"abundant body fluids nourish kidney yin,and abundant kidney yin supports semen production".Therapies such as purging fire to preserve body fluids with Zengye Decoction,nourishing yin to enrich essence with Guilu Erxian Decoction,benefiting qi to promote fluid production with Buzhong Yiqi Decoction,and warming yang and transporting fluids with Xianfu Shezi Decoction should be considered.Medication and dosage adjustments should be made based on the specific etiology,pathology,and related symptoms to improve the quality of male sperm and enhance the chances of conception.

Objective:To compare the clinical efficacy and complications of intra-arterial chemotherapy (IAC) and intravenous chemotherapy (IVC) for unilateral advanced retinoblastoma (RB).Methods:A retrospective clinical study. From January 2020 to January 2021, 40 patients (40 eyes) unilateral group cT2 RB patients diagnosed at Baoding Children’s Hospital and Beijing Children’s Hospital were recruited in this study. There were 22 males (22 eyes) and 18 females (18 eyes). All were monocular. All the patients were assigned to two groups according to different treatment modalities they received: IVC group and IAC group. There were 26 eyes and 14 eyes, respectively. When the tumor invades the optic nerve, choroid, sclera, anterior chamber and iris, enucleation was performed. The globe salvage rate, tumor extraocular metastasis rate, solid tumor control rate, treatment-related complications and pathological high-risk factors after enucleation were observed. The globe salvage rate and solid tumor control rate were compared between the groups by chi square test.Results:The globe salvage rate of IAC group and IVC group were 88.5% (23/26) and 50.0% (7/14), respectively. Solid tumor control of IAC group and IVC group were 84.6% (22/26) and 42.9% (6/14), respectively. There were statistically significant differences in globe salvage rate and solid tumor control between the two groups ( χ 2=7.18, 7.56; P<0.05). Compared with IVC group, IAC group had less systemic complications, mild ocular and periocular side effects. Among 26 cases in IAC group and 14 cases in IVC group, 3 and 7 cases underwent enucleation respectively. The results of pathological examination showed that there were 2 cases and 3 cases with pathological high-risk factors in the two groups, respectively. During the follow-up period, 2 cases in IAC group had extraocular metastasis, there was no extraocular metastasis in IVC group. Conclusion:Compared with IVC, IAC has the advantages of high tumor control rate, high globe salvage rate, less and mild complications, however, there is still tumor recurrence.

Objective:To explore the optimal matching of the current parameters about artificial facial nerve (AFN) for inducing contraction of the orbicularis oris muscle (OOM) in rabbit with peripheral facial paralysis.Methods:According to the combinations of different stimulus parameters, at different time points, we used AFN to induce contraction of the affected side OOM of the paralyzed rabbit in waking state. We recorded the current amplitudes of the threshold stimulation and peak stimulation under each combination, then compared the total charge of the stimulus consumption under different combinations.Results:Compared the total stimulus charge consumption of the AFN threshold stimulation and that in the peak stimulation respectively under different stimulus frequency and pulse width matching combinations, we found that the frequency, the pulse width and the interaction of the frequency and pulse width among different groups could affect the total charge, the differences were statistically significant ( P<0.05). Conclusions:When AFN stimulus frequency is 60 Hz and the stimulus pulse width is 100 μs, the output current intensity is relatively lowest and the total consumed charge is the lowest under the premise of effectively inducing the paralytic side OOM contraction. Thus we recommend this stimulus parametric combination as the optimal combination for meeting the low power consumption of AFN.

Objective: To explore the clinical effect of artificial dermis on partial nail bed defects. Methods: From May 2013 to September 2016, 16 cases of 21 fingers with partial nail bed defect and bone exposure received primary repair with artificial dermis after debridement. Then the outer dressing was changed 3 days after the operation, and the dressing was changed once every 3 to 5 days. The pink dermis like tissue was placed on the wound surface 2 to 3 weeks after the operation. The wound surface was naturally epithelialized. Results: All the fingers were survived after artificial dermis repair, and the fingertip surface of nail bed defect was epithelialized naturally and healed well. Postoperative follow-up was 5 to 16 months, with an average of 8.2 months. The growth of fingernails was smooth with symmetrical appearance, natural toughness, good adhesion between the nail body and the nail bed, and no pain or hyperesthesia at the tip. Results of curative effect evaluation showed excellent in 18 fingers, good in 3 fingers. Results of patient′s satisfaction with postoperative finger appearance showed very satisfactory in 13 cases and satisfactory in 3 cases. Conclusions The method of repairing partial defect of nail bed using artificial dermis is simple with minimal damage and a good clinical effect.

Objective: To explore the optimal positions of the implanted stimulating eletrodes for artificial facial nerve (AFN) for inducing contraction of the orbicularis oris muscle (OOM) in rabbit with peripheral facial paralysis. Methods: According to the four microelectrodes of the AFN stimulating side, four modes of the implanted positions were divided. In line with different modes, the electrodes were implanted into the affected OOM of the rabbits with unilateral peripheral facial paralysis. AFN output electric stimulation to induce contraction of the affected OOM with uniform stimulating frequency and pulse length in vitro. Then compared the stimulus threshold amplitude and the peak amplitude separately among different modes by SAS 9.3 version statistical software. Results: The differences of the stimulus threshold amplitude and the peak amplitude had no statistically significant separately between the first mode and the second mode (P>0.05), but there were statistically significant differences between the third mode and the fourth mode (P<0.05). Both kinds of the amplitudes were approximated between the first mode and the second mode respectively, and higher than those in the third mode or the fourth mode. Furthermore, both kinds of the amplitudes in the fourth mode were higher than those in the third mode. Conclusions The microelectrodes of the AFN stimulating lateral are implanted into the upper lip with a public microelectrode and an output microelectrode, into the lower lip with an output microelectrode, and into the way, which is located to the angle 40° to 45° about the line joining between the midpoint of the ipsilateral auricle root and the corner of the mouth with an output microelectrode. This is the third positional mode which requires lowest effective stimulus current intensity. Thus the mode is suitable as the optimal placement programme.
