OBJECTIVE:
To explore the relationship between spinous process deviation and lumbar disc herniation in young patients.
METHODS:
From March 2015 to January 2022, 30 treated young (under the age of 30) patients with lumbar disc herniation were included as the young group. In addition 30 middle-aged patients (quinquagenarian group) with lumbar disc herniation and 30 patients with non-degenerative spinal diseases (young non-degenerative group) were selected as control groups. The angle of the spinous process deviation was measured on CT and statistically analyzed by various groups. All the data were measured twice and the average value was taken and recorded.
RESULTS:
The average angle of spinous process deviation in the degenerative lumbar vertebra of young patients were (3.89±3.77) degrees, similar to the (3.72±2.98) degrees of quinquagenarian patients(P=0.851). The average angle of s spinous process deviation young non-degenerative group were (2.20±2.28) degrees, significantly less than young group(P=0.040). The spinous process deviation angle of the superior vertebral of the degenerative lumbar in the young group was (4.10±3.44) degrees, which similar to the (3.47±2.87) degrees in the quinquagenarian group (P=0.447). A total of 19 young patients had the opposite deviation direction of the spinous process of the degenerative lumbar vertebra and upper vertebra, while only 7 quinquagenarian patients had this condition(P=0.02). The type of lumbar disc herniation in young patients had no significant relationship with the direction of spinous process deflection of the degenerative or upper lumbar vertebra (P>0.05).
CONCLUSION
Spinous process deviation is a risk factor of young lumbar disc herniation patients. If the deviation directions of adjacent lumbar spinous processes are opposite, it will increase the incidence of lumbar disc herniation in young patients. There was no significant correlation between the type of disc herniation and the deviation direction of the spinous process of the degenerative or upper lumbar vertebra. People with such anatomical variation can strengthen the stability of spine and prevent lumbar disc herniation through reasonable exercise.

Medicinal plants are the main source of clinical medication in traditional Chinese medicine(TCM). China has achieved large-scale cultivation and production of medicinal plants. As an important resource for the sustainable development of agriculture in the future, microorganisms can also promote the green, ecological and high-quality development of Chinese medicine agriculture. However, research on the medicinal plant microbiome is still limited. Therefore, based on the development timeline of microbiome research, the present study reviewed the origin, technology, and hotspots of microbiome research and proposed some suggestions for future research according to the advances in medicinal plant microbiome.(1)Systematic investigation of medicinal plant microbiome on the species, genus, and family levels should be carried out on the medicinal plants of different chemotypes in order to reveal the coevolution of the microorganisms and their host plants.(2)Spatial and temporal research on medicinal plant microbiome should be performed to reveal the effects of microorganisms on the growth, development, and secondary metabolite accumulation of medicinal plants, as well as the underlying mechanisms.(3)Model medicinal plant species should be selected and microorganism-plant interaction research models should be established.(4)Core microbiome of medicinal plants should be explored for the future application of crucial microbes in the sustaina-ble agriculture of Chinese medicine.(5)Breeding of medicinal plant-associated microbes should be carried out to lay the foundation for novel medicinal plant breeding strategies.(6)High-throughput sequencing, traditional incubation, and isolation of microbes should be combined to study medicinal plant microbiome, thereby promoting the exploitation and application of uncultured microbial strains.(7)Platforms for the preservation of medicinal plant-associated microbe strains and data of their metabolites should be established and the exchange of information and cooperation between these platforms should be subsequently enhanced. With these suggestions, the efficient and rapid development of medicinal plant microbiome research is expected to be promoted.

A retrospective cohort study was conducted at the Children's Hospital of Chongqing Medical University from November 2004 to December 2020 to investigate the long-term follow-up results after testicular torsion (TT) in children. Boys with TT were divided into the salvage orchiopexy group and the orchiectomy group, and the baseline characteristics, ultrasonographic indications, intraoperative findings, testicular volumes, and adverse events during follow-up were compared. A total of 145 cases were included in this study. Approximately 56.6% of patients who underwent salvage orchiopexy had testicular atrophy (TA), and the median testicular volume loss of the testes was 57.4%. Age less than 6 years, delayed surgery, and intraoperative poor blood supply were associated with TA in pediatric TT after orchiopexy. Most atrophied testes appeared within 3-6 months after surgery. Compared with the corresponding age-matched healthy controls, the contralateral testicular volumes were larger in the orchiopexy (P = 0.001 without TA, and P = 0.042 with TA) and orchiectomy groups (P = 0.033). The adverse events were comparable in patients with orchiectomy or orchiopexy. In summary, follow-up before 3 months after surgery may not offer sufficient clinical value, while that 3 months after surgery should be regarded as the first follow-up time for testicular monitoring. The contralateral testes of patients with TT showed compensatory hypertrophy. We suggest performing orchiectomy when torsed testes are surgically assessed as Arda grade III or inviable.

According to Chinese medicine, the atlantoaxial joint is a composite joint composed of tendons and bones, and the stability of the joint depends on the 'tendon-bone balance' involving tendons, ligaments, atlas and axis. Multiple causes of 'tendon off-position, joint subluxation' will lead to joint 'tendon-bone imbalance', which will evolve into atlantoaxial subluxation (AAS), endangering human health. Chinese therapeutic massage (tuina) is a very effective treatment for AAS in adults, but conventional manipulations are prone to ineffectiveness or accidents due to neglect of the causal relationship of the 'tendon-bone imbalance' and inappropriate manipulations. Compared with conventional manipulations, the rational choice of modified manipulations under the guidance of 'tendon-bone balance' theory is more effective and less risky, and more worthy of clinical promotion. From the 'tendon-bone balance' theory, we considered the shortcomings of conventional manipulations, and introduced several modified manipulations that have their own strengths in 'tendon smoothing' and 'bone setting', in order to provide new ideas for treatment of AAS in adults.

Intestinal Peyer's patches (PPs) are local immune tissues of the intestine, which are considered to be the main induction site of the intestinal mucosal immune response, and closely related to immune-related refractory enteropathies, such as ulcerative colitis and Crohn's disease. In recent years, more and more scholars have tried to find a new breakthrough for treating refractory enteropathies with a limited efficacy of clinical interventions through in-depth study of the relationship between PPs and enteropathy. Traditional Chinese medicine (TCM) polysaccharides are considered to be a key component for immune regulation with TCM. Modern studies show that TCM polysaccharides have a significant positive intervention effect on the structure and function of PPs, with good development prospects. Based on this, this paper focuses on PPs and intestinal-related diseases, and systematically introduces the physiological structure of PPs and their drug delivery mechanism, and summarizes the interactions of PPs with effect on immune-related enteropathies, analyze of current studies and prospects of effect of TCM polysaccharides in intervening intestinal disease and its dysfunction by regulating PPs, with the aim to provide new strategies for basic studies and clinical treatment of immune-related refractory enteropathies from the perspective of PPs, and new ideas for basic studies and clinical studies on effect of TCM polysaccharides in intervening enteropathies.

Traditional Chinese medicine (TCM) and western medicine have their respective advantages and limitations in the diagnosis and treatment of common otorhinolaryngology head and neck diseases. Although the integrated TCM and western medicine exhibits definite curative effects, there is no consensus on the otorhinolaryngology head and neck diseases responding specifically to TCM or integrated TCM and western medicine, as well as the diagnosis and treatment schemes. The China Association of Chinese Medicine (CACM) thus organized the otorhinolaryngology head and neck specialists of both TCM and western medicine to discuss the etiology, pathogenesis, and clinical diagnosis and treatment methods of common otorhinolaryngology head and neck diseases with the results of multiple clinical trials taken into account. The acute pharyngitis, chronic pharyngolaryngitis, paraesthesia pharyngis, hysterical aphasia, allergic rhinitis, subjective tinnitus, and otogenic vertigo were confirmed to respond specifically to TCM or integrated TCM and western medicine. Then a mutually agreed diagnosis and treatment scheme and recommendation with integrated TCM and western medicine was formulated as a reference for clinical practice, thus benefiting more patients.

Journal of Peking University(Health Sciences) 2021;53(3):613-622
OBJECTIVE:
To construct a preoperative evaluation system for partial nephrectomy using CT three-dimensional visualization technology and to explore its practical value.
METHODS:
The clinical data of the patients who underwent partial nephrectomy for renal tumors in Department of Urology, Peking University First Hospital were collected retrospectively. At the same time, the homogenized standard data of patients who underwent partial nephrectomy for renal tumors were collected in 16 clinical centers in China. The CT three-dimensional visualization system was applied (IPS system, Yorktal) to evaluate tumor anatomy, blood supply, perirenal fat and other information. The parameters were summarized to build a three-dimensional nephrometry system, on the basis of which virtual surgery design and intraoperative navigation were completed.
RESULTS:
A three-dimensional visualization image was established based on the enhanced CT urography. The nephrometry system included the longest diameter and volume of the tumor, proportion volume of tumor invading the parenchyma, maximum depth of the tumor invading the parenchyma, contact surface area, flatness of the tumor surface, renal segment where the tumor was located, vascular variation, and perirenal fat. The average two-dimensional diameter of the tumor was (2.78±1.43) cm, the average three-dimensional maximum diameter was (3.09±1.35) cm, and the average postoperative pathological size was (3.01±1.38) cm. The maximum tumor diameter in the three-dimensional image was significantly related to the prolonged renal artery clamping time and intra-operative blood loss (r=0.502, P=0.020; r=0.403, P=0.046). The three-dimensional and pathological tumor volume were (25.7±48.4) cm3 and (33.0±36.4) cm3, respectively (P=0.229). The tumor volume was significantly related to the intraoperative blood loss (r=0.660, P < 0.001). The proportion volume of the tumor invading into renal parenchyma was significantly related to the prolongation of renal artery clamping and the occurrence of postoperative complications (r=0.410, P=0.041; r=0.587, P=0.005). The tumor contact surface area and the presence of vascular variation did not show correlation with the perioperative data and postoperative complications. While the preoperative evaluation was completed, the reconstructed three-dimensional image could be zoomed, rotated, combined display, color adjustment, transparency, and simulated cutting on the Touch Viewer system. The process generally consisted of showing or hiding the tissue, adjusting the transparency of the interested area, rotating and zooming the image to match the position of the surgical patient. Together, these functions met the requirements of preoperative virtual surgery plan and intraoperative auxiliary navigation.
CONCLUSION
Three-dimensional images can provide a more intuitive anatomical structure. The CT three-dimensional visua-lization system clearly displays tumor anatomical parameters, blood supply and perirenal fat. The three-dimensional nephrometry system for renal tumors can help predict the difficulty of partial nephrectomy and perioperative complications. Importing the reconstructed three-dimensional visualization image into the specified program or robot operating system can complete virtual surgery and intraoperative navigation, helping the surgeon to better grasp the surgical process. The indexes included in the nephrometry system and the score weights of each index need to be confirmed and perfected by multi-center study with large samples.

Journal of Peking University(Health Sciences) 2021;53(5):891-895
OBJECTIVE:
To bring forward an arthroscopic classification of the popliteal hiatus of the lateral meniscus (PHLM) tears and to assess the effects of arthroscopic all-inside repair with suture hook in management of such injuries.
METHODS:
This study involved 146 patients who underwent arthroscopic operation because of PHLM tears from April 2014 to October 2017, eliminating the patients who had discoid lateral meniscus. There were 81 males and 65 females, with 54 left knees and 92 right knees. The average ages were (34.7±3.7) years. Among the selected participants, there were 107 patients with anterior cruciate ligament (ACL) injuries, 39 patients with medial collateral ligament (MCL) injuries, and 48 patients with medial meniscus tears. The average preoperative Lysholm and International Knee Documentation Committee (IKDC) scores were 57.7±9.2 and 54.1±8.9, respectively. The arthroscopic classification was based on the extent and degree of PHLM tears and using the arthroscopic all-inside repair with suture hook for such injuries. For the patients associated with ACL injuries, the ipsilateral autograft hamstring tendons use as the reconstruction graft for single bundle ACL reconstructions. The suture anchors were used for treatment of MCL Ⅲ injuries, and the arthroscopic all-inside repair for medial meniscus tears.
RESULTS:
A total of 146 PHLM tears in 146 patients were divided into type Ⅰ (tears not involved in popliteus tendon incisura; n=86, 58.9%), type Ⅱ (tears involved in popliteomeniscal fascicles; n=36, 24.7%), and type Ⅲ (tears involved in popliteus tendon incisura; n=24, 16.4%). For type Ⅰ, there were three subtypes, including type Ⅰa: longitudinal tear (n=53, 61.6%), type Ⅰb: horizontal tear (n=27, 31.4%), and type Ⅰc: radial tear (n=6, 7.0%). For type Ⅱ, there were also three subtypes, including type Ⅱa: anterosuperior popliteomeniscal fascicle tear (n=5, 13.9%), type Ⅱb: posterosuperior popliteomeniscal fascicle tear (n=20, 55.6%), and type Ⅱc: both tears (n=11, 30.6%). For type Ⅲ, there were two subtypes, including type Ⅲa: horizontal tear (n=9, 37.5%), type Ⅲb: radial tear (n=15, 62.5%). In the follow-up for an average of 15.3±2.6 months, all the patients had done well with significantly improved Lysholm (84.6±14.3) and IKDC (83.2±12.8) scores at the end of the last follow-up relative to preoperative scores (P > 0.01).
CONCLUSION
We propose that it is possible to classify lateral meniscus tears at the popliteal hiatus region for three types, which can summarize the injury characteristics of this area. The arthroscopic all-inside repair with suture hook for the PHLM tears can avoid stitching to popliteal tendon or narrowing popliteal hiatus and have satisfactory clinical results.
