Objective: To evaluate the safety and efficacy of the retroauricular transmeatal approach in the treatment of condylar head and neck fractures, and to provide a reference for clinical practice. Methods: This study has been reviewed and approved by the institutional medical ethics committee and has obtained informed consent from the patients. A retrospective analysis was conducted on the clinical data of patients with condylar head and neck fractures treated via the retroauricular transmeatal approach between March and October 2024. Postoperative follow-up was performed for at least 3 months, including clinical and radiographical evaluations. The assessed parameters included facial nerve function, temporal region numbness, hematoma, infection, salivary fistula, mouth opening, malocclusion, mandibular movement function, temporomandibular joint (TMJ) pain and clicking, external auditory canal (EAC) stenosis, hearing function impairment, surgical scar concealment, postoperative reduction and fixation outcomes. Results: A total of 16 patients with condylar fractures were treated via the retroauricular transmeatal approach, including 10 unilateral and 6 bilateral cases. Specifically, 18 sides were condylar head fractures, and 4 sides were condylar neck fractures. All patients achieved a House-Brackmann Grade I, indicating normal facial nerve function postoperatively. On postoperative day 1, 3 sides experienced temporal numbness in the temporal region on the surgical side, with spontaneous resolution in all cases. All patients recovered after surgery without hematoma, infection, or salivary fistula. Limited mouth opening was improved (14 cases with restricted mouth opening preoperatively vs. 3 cases postoperatively). No malocclusion occurred in any patient. All patients achieved satisfactory recovery of postoperative mandibular movement function, manifested as restored range of motion without pain. No TMJ clicking was observed within 3 months after surgery. One keloid-prone patient developed progressive EAC stenosis (2 mm lumen constriction) accompanied by conductive hearing impairment, which recovered after dilation therapy. All patients were satisfied with the aesthetic outcomes. Radiographically parametric assessment demonstrated satisfactory fracture reduction and fixation; with no loosening of titanium plates or screws. Conclusion The retroauricular transmeatal approach effectively reduces the risk of facial nerve injury and salivary fistulas formation with providing concealed scarring and high patient satisfaction. However, caution should be exercised regarding EAC stenosis, especially for keloid-prone patients.

Objective To systematically evaluate the efficacy and safety of video-assisted thoracoscopic surgery (VATS) with different numbers of ports in the treatment of spontaneous pneumothorax. Methods We conducted a comprehensive search of CNKI, PubMed, The Cochrane Library, Web of Science, EMbase, Wanfang Data, and the Chinese Medical Journal Full-text Database for clinical controlled trials on VATS with different port numbers for spontaneous pneumothorax, from their inception to March 2023. Two researchers independently screened the literature and assessed its quality.The Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of cohort and case-control studies, and the Cochrane risk-of-bias tool was used to evaluate randomized controlled trials (RCT). Meta-analysis was performed using RevMan 5.4.1 software. Results A total of 107 studies were included, comprising 35 RCT, 2 cohort studies, and 70 case-control studies. All cohort and case-control studies included in the analysis had NOS scores≥7. The meta-analysis revealed that compared to two-port VATS (2P-VATS) and three-port VATS (3P-VATS), single-port thoracoscopic surgery (SPTS) was associated with less intraoperative blood loss (SMD=–1.58, 95%CI: –1.93 to –1.22, P<0.001; and SMD=–1.59, 95%CI: –2.03 to –1.14, P<0.001, respectively), shorter postoperative hospital stay (SMD=–1.05, 95%CI: –1.29 to –0.82, P<0.001; and SMD=–1.08, 95%CI: –1.39 to –0.77, P<0.001), shorter duration of postoperative chest tube drainage (SMD=–0.75, 95%CI: –1.00 to –0.50, P<0.001; and SMD=–1.23, 95%CI: –1.72 to –0.75, P<0.001), fewer postoperative complications (OR=0.34, 95%CI: 0.26 to 0.45, P<0.001; and OR=0.47, 95%CI: 0.33 to 0.68, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P<0.05). The operative time for SPTS was shorter than that for 2P-VATS (SMD=–0.53, 95%CI: –0.90 to –0.16, P=0.005) but showed no significant difference compared to 3P-VATS (P=0.21). When comparing 2P-VATS with 3P-VATS, 2P-VATS demonstrated less intraoperative blood loss (SMD=–1.02, 95%CI: –1.81 to –0.22, P=0.01), shorter postoperative hospital stay (SMD=–0.59, 95%CI: –1.11 to –0.06, P=0.03), shorter duration of chest tube drainage (SMD=–0.46, 95%CI: –0.85 to –0.08, P=0.02), fewer postoperative complications (OR=0.36, 95%CI: 0.22 to 0.59, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P≤0.05). Conclusion Both SPTS and 2P-VATS are effective and safe surgical options for spontaneous pneumothorax, deserving further promotion and application in clinical practice. However, due to limitations in the quantity and quality of the included studies, more large-sample, high-quality research is needed to validate these findings.

Objective To systematically evaluate the efficacy of immune checkpoint inhibitors (ICIs) in treating esophageal cancer patients of different genders. Methods Computer searches were conducted on PubMed, Cochrane Library, and Embase databases to collect randomized controlled trial (RCT) on ICIs treatment for esophageal cancer patients from the establishment of the databases to January 25, 2024. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. The outcome indicators were overall survival (OS) and progression-free survival (PFS), and RevMan 5.4 software was used for meta-analysis. The modified Jadad scoring scale was used to evaluate the quality of the included literature. Results A total of 10 RCT involving 5364 esophageal cancer patients were included in this study, with 2684 patients in the trial group and 2680 patients in the control group. The Jadad scores of the included literature were all ≥6 points, indicating high-quality RCT. Meta-analysis results showed that female esophageal cancer patients receiving ICIs treatment [HR=0.72, 95%CI (0.59, 0.87), P<0.001] had a more significant median OS prolongation than male patients [HR=0.73, 95%CI (0.68, 0.78), P<0.001]; while male patients [HR=0.57, 95%CI (0.52, 0.64), P<0.001] had a more significant PFS prolongation than female patients [HR=0.72, 95%CI (0.55, 0.94), P=0.01]. Female patients treated with ICIs alone [HR=0.66, 95%CI (0.50, 0.87), P=0.003] had a more significant median OS prolongation than male patients [HR=0.79, 95%CI (0.72, 0.87), P<0.001]; while male patients receiving ICIs combined with chemotherapy [HR=0.67, 95%CI (0.61, 0.74), P<0.001] had a more significant median OS prolongation than female patients [HR=0.77, 95%CI (0.59, 1.01), P=0.06]. Conclusion Female patients receiving ICIs have a slight advantage in OS compared to male patients, while male patients have an advantage in PFS. Male patients receiving ICIs combined with chemotherapy have better survival benefits than female patients, while female patients using ICIs monotherapy have better survival benefits than male patients.

Houpo Qiwutang originated from the Synopsis of the Golden Chamber， and it consists of seven medicines： Magnoliae Officinalis Cortex， Rhei Radix et Rhizoma， Aurantii Fructus Immaturus， Cinnamomi Ramulus， Zingiberis Rhizoma Recens， Glycyrrhizae Radix et Rhizoma， and Jujubae Fructus. It is a basic formula for the treatment of abdominal fullness. Through the bibliometric method， the historical history， drug base， preparation and dosage， decoction method， and ancient and modern applications of Houpu Qiwu Tang were analyzed by means of textual research. The research finds that Houpu Qiwu Tang has been passed down through the generations in an orderly manner with fewer changes. The drug base of this formula is basically clear， and the base of Magnoliae Officinalis Cortex， Rhei Radix et Rhizoma， Cinnamomi Ramulus， Zingiberis Rhizoma Recens， and Jujubae Fructus is consistent with the 2020 edition of Chinese Pharmacopoeia. The mainstream base of Aurantii Fructus Immaturus is the dried young fruit of Citrus aurantium of Rutaceae family， and the historical mainstream base of Glycyrrhizae Radix et Rhizoma is the dried root of Glycyrrhiza uralensis of Leguminosae family. The modern dosage of this formula is 110.40 g of Magnoliae Officinalis Cortex， 41.40 g of Rhei Radix et Rhizoma， 69 g of Aurantii Fructus Immaturus， 27.60 g of Cinnamomi Ramulus， 69 g of Zingiberis Rhizoma Recens， 41.40 g of Glycyrrhizae Radix et Rhizoma， and 30 g of Jujubae Fructus. In addition， the decoction method is to add 2 000 mL of water with the above seven flavors of the medicine， boil it to 800 mL， and then take 160 mL in a warm state each time. The amount of the medicine taken for each time is 22.08 g of Magnoliae Officinalis Cortex， 8.28 g of Rhei Radix et Rhizoma， 13.80 g of Aurantii Fructus Immaturus， 5.52 g of Cinnamomi Ramulus， 13.80 g of Zingiberis Rhizoma Recens， 8.28 g of Glycyrrhizae Radix et Rhizoma， and 6 g of Jujubae Fructus. The modern application of this formula involves the digestive system， respiratory system， and urinary system. It is more advantageous in digestive system diseases such as early postoperative inflammatory bowel obstruction， functional dyspepsia， gastric pain， functional abdominal distension， and gastric reflux esophagitis. By comprehensively examining the key information of Houpu Qiwu Tang， this paper aims to provide literature support for the development and clinical application of this formula.

Objective:To investigate the effect of a new method of utilizing frontalis sling with polypropylene non-absorbable sutures for the treatment of senile ptosis.Methods:A retrospective analysis was conducted on the clinical data of senile patients with blepharoptosis who were treated with frontalis sling surgery with polypropylene non-absorbable sutures at the Department of Plastic Surgery, Affiliated Hospital of Nanjing University of Chinese Medicine between January 2022 and December 2023. The palpebral fissure height and margin reflex distance (MRD1) of the upper eyelid margin were measured and recorded before and after the operation, and the operation time and postoperative detumescence time were recorded. Postoperative complications and recurrence of ptosis were followed up. Patients’ satisfaction with the postoperative effect was investigated and divided into three levels: very satisfied, satisfied, and dissatisfied. Normal distribution measurement data were expressed as Mean±SD; counting data were expressed as frequency.Results:A total of 8 patients were enrolled, including 3 males and 5 females, with an age of (68.8±6.1) years. Six patients underwent bilateral ptosis correction surgery, and two underwent unilateral ptosis correction surgery. The ptosis was graded as follows: 1 case was mild, 2 cases were moderate, and 5 cases were severe. There were 2 cases of aponeurotic ptosis, 3 cases of congenital ptosis and 3 cases of traumatic ptosis (1 of which was prosthetic eye). The operative time of 8 patients (14 eyes) with unilateral ptosis was (43.9±4.9) min. The swelling resolved in (9.4±1.7) days. One patient still had symptoms of lagophthalmos and corneal irritation 7 days after the operation. The symptoms gradually relieved after wearing corneal protective goggles and applying eye ointment. The postoperative follow-up lasted from 2 to 15 months (mean 6.3 months). Palpebral cleft height [(9.8±0.6) mm vs. (3.3±1.2) mm] and MRD1[(4.1±0.5) mm vs. (-1.1±0.8) mm] in 8 patients (14 eyes) after surgery were significantly higher than those before the operation( P<0.01). There was no recurrence of ptosis after the operation. There were 2 cases of upper eyelid hysteresis, of which 1 case was mild upper eyelid hysteresis, and the other case had relatively obvious upper eyelid hysteresis on prosthetic side. Satisfaction survey showed that 7 patients were very satisfied with the result of the operation, and 1 patient was satisfied. Conclusion:Frontal muscle suspension with polypropylene non-absorbable suture is a feasible method for the treatment of ptosis in elderly patients with simple operation, little tissue damage, positive effect, rapid postoperative recovery and acceptable complications.

Purpose To evaluate the static structural changes of mitral annulus and leaflets in mitral valve prolapse via three-dimensional transesophageal echocardiography(3D-TEE),and their continuous dynamic changes during the cardiac cycle.Materials and Methods Twenty-six patients with mitral valve prolapse diagnosed by transesophageal echocardiography in Wuhan Asia Heart Hospital from June 2022 to June 2023 were retrospectively included,and 30 patients who were examined by transesophageal echocardiography in our hospital during the same period due to monitoring of patent foramen ovale or non-cardiac surgery were selected as the control group.The related parameters of the valve annulus were measured.In addition,the meaningful parameters were measured at late diastole(LD),early systole(ES),middle systole(MS)and late systole(LS),and the change rate was calculated.The static structure of mitral valve device was compared between the two groups,and the differences of various parameters at different times were analyzed.Results Compared with the control group,the annulus height(AH)and the ratio of annulus height and combined width(AHCWR)in the case group decreased,and the other parameters increased(t=-7.447-12.472,all P<0.05),but there was no statistical difference in the maximum displacement distance of the annulus between the two groups(P>0.05).Comparing the related parameters of LD,ES,MS and LS at four different time points,compared with the control group,all the parameters in the case group increased except AH and AHCWR(t=-16.224-15.683,all P<0.05).Comparing the continuous changes at four different times,the continuous changes of all parameters in the control group were statistically significant(F=7.632-323.837,all P<0.05),and there were significant differences in the parameters of the control group from LD to ES(all P<0.05).Except anterolateral to posteromedial diameter,intertrigonal diameter and annulus area,the continuous changes of other parameters in the case group were statistically significant(F=3.041-71.082,all P<0.05),and only non-planar angle,AH and AHCWR in the case group had statistical differences in LD to ES(all P<0.05).Compared with the control group,the change rate of parameters in the case group decreased,and the difference was statistically significant(t/U=-7.069-780.000,all P<0.05),and the change rate of C-ring was greater than that of intertrigonal diameter.Conclusion 3D-TEE can quantitatively analyze the dynamic changes of mitral annulus and leaflets,and analyze the continuous changes of mitral valve in cardiac cycle in detail,which can provide more accurate preoperative evaluation for patients and guide treatment.

Objective:To summarize the experience of designing hair transplantation for post-cleft lip repair moustache defects based on the morphological and tissue characteristics of the upper lip.Methods:A retrospective analysis was conducted on the clinical data of male patients treated at the Hair Transplantation Center of Plastic Surgery Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from January 2011 to July 2024. Based on the morphology and tissue texture of the upper lip after cleft lip repair, the position and shape of the moustache were designed. Hair follicles were harvested from the mid-occipital region and/or the jaw shadow area using either the strip harvesting method or the follicular unit excision (FUE) technique. Needles of 21 or 22 gauge were used to create incisions in the recipient sites down to the superficial subcutaneous layer. The hair shafts were clamped with micro-forceps and then transplanted into the recipient sites to restore the moustache shape. Postoperatively, the density, shape, direction of the moustache, and the condition of the donor site scars were observed and followed up.Results:A total of 47 male patients, aged 23-43 years (mean 28.7 years), were included. Among them, 29 had undergone lower triangular flap repair, 13 received the Millard technique, and 5 were treated with other surgical methods for cleft lip repair. For hair follicle extraction, the strip method was used in 7 cases, and FUE in 40 cases. The donor sites included the jaw shadow area (9 cases), mid-occipital region (23 cases), and a combination of both (15 cases). The number of transplanted follicular units ranged from 33 to 500 (mean 217). Follow-up duration ranged from 9 months to 10 years (mean 3.5 years). Postoperative complications included folliculitis in 6 cases, and 4 cases required additional transplantation due to insufficient density after one year. The remaining patients exhibited satisfactory hair growth, with natural mustache shape and direction. The graft survival rate was approximately 80%, and donor site scarring was minimal.Conclusion:When performing hair transplantation to treat post-cleft lip repair moustache defects, the design should prioritize the morphological and tissue characteristics of the upper lip, followed by consideration of overall position and bilateral symmetry of the moustache. Only by fully considering the characteristics of the recipient area can optimally repair outcomes be achieved.

In recent years, non-alcoholic fatty liver disease (NAFLD) is the fastest growing pathogenic factor of primary liver cancer (PLC). Compared with virus-associated hepatocellular carcinoma (HCC), HCC associated with NAFLD has a unique immune microenvironment, and combined treatment with corresponding targets can improve the immunetherapeutic efficacy. However, prospective studies are still needed for the immunotherapy response of different causes of PLC is different and the therapeutic efficacy has not reached consensus. The high-level evidence of etiology stratification, personalized precision immunotherapy and combinational therapy may be the future milestones in this area. We hereby reviews the epidemiology, tumor microenvironment, and immunotherapy of NAFLD-related HCC.
