Objective:To explore the therapeutic effect of acupuncture plus Zi Shen Tiao Gan (Kidney-reinforcing and Liver-regulating) Decoction for perimenopausal women with insomnia.
Methods:A total of 126 eligible cases were randomly divided into two groups, 63 cases in each group. Patients in the observation group were given acupuncture plus Zi Shen Tiao Gan (Kidney-reinforcing and Liver-regulating) Decoction. Those in the control group were treated with the same acupuncture treatment as the observation group. The therapeutic effects were assessed after continuous treatment for four weeks.
Results:The total effective rate was 96.8%in the observation group and 74.6%in the control group. The comparison of the total clinical effects between the two groups was statistically significant (P<0.01). After treatment, the intra-group comparisons of SPIEGEL score were statistically significant in both groups (P<0.05, P<0.01);the inter-group comparison of SPIEGEL score difference between before and after treatment was statistically significant (P<0.05).
Conclusion: Acupuncture plus Zi Shen Tiao Gan (Kidney-reinforcing and Liver-regulating) Decoction for perimenopausal insomnia is affirmative in the therapeutic effect, and the therapeutic effect is better than simple acupuncture treatment.

Melorheostosis is a rare disorder of osteopathia. The clinical characteristics of melorheostosis in children is totally different from that in adults. The radiographic features of melorheostosis include the hyperostosis in endosteal on the one side of the cavum medullare and formed streakiness. The soft tissue contracture of the limb and joint deformities are the symptoms of melorheostosis. Here, the authors reported a melorheostosis case of 6 years old girl who suffered from severe valgus deformity of the right knee with permanent patellar dislocation. A surgical stabilization was applied with lateral soft tissue release, medial soft tissue stabilization and transferred the vastus medialis laterally (kinetic stability). After 19 years follow up postoperatively, the limb developed well in satisfied alignment with good function of knee joints, even participated in some sports activities. Other authors reported a similar case of melorheostosis with surgical treatment and achieved good outcomes in limb realignment and reduction. The further suggested that the surgical treatment should be produced before epiphyseal closure.

Objective:To explore the correlation between the indexes of tongue coating exfoliated cells and the Traditional Chinese Medicine (TCM) syndromes of patients with chronic gastritis.Methods:One hundred and forty-eight patients with chronic gastritis in our hospital from March 2017 to May 2018 were selected and divided into 4 groups, including 36 patients with spleen and stomach weakness syndrome, 39 patients with liver-stomach discordance syndrome, 32 patients with stomach yin deficiency syndrome, and spleen and 41patients with stomach damp-heat syndrome according to the TCM classification. In addition, another 50 healthy people without cold and heat deficiency syndrome were selected as healthy control group. The maturity index (MI) and mature value (MV) of tongue coating exfoliated cells, chemical indicators and cell cycle of tongue coating exfoliated cells were detected. The spearman rank correlation method was used to analyze the indicators of tongue coating exfoliated cells and TCM syndromes.Results:Compared with the healthy control group, the subjects with spleen and stomach weakness syndrome, liver-stomach discord syndrome, stomach-yin deficiency syndrome, spleen-stomach damp-heat syndrome showed significantly higher percentage of intermediate cells [(14.85 ± 4.03) % vs. (26.47 ± 3.94) %, (22.32 ± 5.41) %, (31.47 ± 3.28) %, (35.62 ± 3.96) %, P<0.05], significantly lower percentage of surface cells [(85.15 ± 5.33) % vs. (73.53 ± 6.47) %, (77.68 ± 5.38) %, (68.53 ± 4.20) %, (64.38 ± 4.39) %, P<0.05], and significantly lower percentage of MV value [(92.61 ± 3.74) % vs. (83.52 ± 3.10) %, (87.64 ± 2.95) %, (79.38 ± 3.21) %, (75.63 ± 2.83) %, P<0.05]. Compared with the healthy control group, the ACP, LDH, SDH, and -SH in tongue coating exfoliated cells of subjects with spleen and stomach weakness syndrome, liver and stomach discordance syndrome, and stomach yin deficiency syndrome were all significantly decreased ( P<0.05), while ACP, LDH, SDH, and -SH in subjects with spleen and stomach damp-heat syndrome were all significantly increased ( P<0.05). the percentage of cells in G1 phase of subjects with gastric yin deficiency and spleen and stomach damp-heat syndrome were significantly decreased ( P<0.05), while the percentage of S phase cells were significantly increased ( P<0.05). Spearman rank correlation analysis showed that each syndrome type was correlated with ACP, LDH, SDH, -SH ( r values were 0.608, 0.712, 0.704, 0.631, respectively, all Ps<0.05). Conclusion:Patients with different TCM syndromes of chronic gastritis may have different morphological changes of tongue coating exfoliated cells, large differences in cell cycle, and different levels of cell biochemical indicators.

Objective:To summarize the morphological characteristics and clinical experience of pulmonary artery sling(PAS) combined with anomalous bronchial branching, and provide new considerations for surgically treating PAS.Methods:A retrospective review of surgical experience of all patients with anomalous bronchial branching from January 2012 to December 2018 at Shanghai Children's Medical Center was conducted. There are 4 types according to the morphology of anomalous bronchial branching: tracheal bronchus, bronchial trifurcation, bridging bronchus, tracheal bronchus combined with bronchial trifurcation. The proportion of patients with anomalous bronchial branching combined with PAS was counted. The rate of tracheoplasty for four types was determined. We measured the interbronchial and subcarinal/subpseudocarinal angles before and after tracheoplasty.Results:140 patients were included in our study. The tracheal diameter of 11(21%, 11/53) patients with tracheal bronchus and 4(9%, 4/44) patients with bronchial trifurcation was normal. Among these patients, 125 patients had congenital tracheal stenosis(CTS). 115 patients underwent tracheoplasty. The rate of tracheoplasty of bridging bronchus was higher than tracheal bronchus(100% vs. 60%, P=0.000). One-stage surgery was performed in 76(61%) patients who had PAS. The interbronchial and subcarinal/subpseudocarinal angles were significantly reduced postoperatively( P=0.000). Conclusion:It is difficult to explain merely with vascular compression in patients with PAS with CTS and anomalous bronchial branching. One-stage slide tracheoplasty is currently the optimal option.

BACKGROUND:As a traditional treatment for multilevel cervical myelopathy,nterior long-segmental decompression has the shortcomings of great operative trauma,high difficulty,low fusion rate,etc.,which can affect the postoperative efficacy.OBJ ECTIVE:To evaluate the clinical effects of three different anterior surgeries on multilevel cervical myelopathy.DESIGN:A comparative observation.SETTING:Department of Orthopaedics,Changzheog Hospital,the Second Military Medical University of Chinese PLA.PARTICIPANTS:Thirty-six patients with multilevel cervical myelopathy of 3 consecutive segments,who were surgically treated,were selected from the Department of Orthopaedics,Changzheng Hospital,the Second Military Medical University of Chinese PLA from June 1999 to June 2003,including 25 males and 11 females,35-62 years of age,the disease course ranged from 3 to 26 months. According to the clinical manifestations and imaging esults,they were diagnosed as multilevel cervical myelopathy,and they were not suffering from consecutive ossification of posterior longitudinal ligament and ossification of ligamenta flava. Informed contents were obtained from all the patients and their relatives.METHODS:All the patients were grafted with utologous bone. Autologous ilium or cancellous bone excluding vertebral body was filled into titan net or Cage,which were made of titan and characterized by high intensity,tolerance to decay,good biocompatibility,etc. According to the operative manner,the patients were divided into 3 groups:① two-level corpectomy with fusion group(long-segmental decompression group,n =11):There were 4 cases grafted with long-titan net,and 7 cases grafted with autologous iliac bone. Sub-total two-level corpectomy with fusion was performed. ②segmental decompression group(n =16):including 12 cases of titan net+cage graft,4 cases of autologous bone+cage graft. One-level decompression and sub-total single corpectomy with fusion were performed. ③three-level decompression group(n =9):Only discectomy without corpectomy was performed. After complete decompression,3cages were used to fill artificial bone or grafted with autologous bone.MAIN OUTCOME MEASURES:Cervical anteroposterior and lateral radiographies,flexion and extension radiograph were reexamined within 1 week and at 3,6 and 12 months postoperatively. The neurological function was assessed using the Japanese Orthopaedic Association(JOA) scoring method preoperatively and 3 months postoperatively. The total score was 17 points,the higher the score,the better the neurological function. The duration of operation,perioperative bleeding amount,length of stay,cost of hospitalization,graft fusion at 3 months postoperatively,improved JOA score at 3 months postoperatively were recorded in the three groups. The occurrence of postoperative complications was observed by means of return visit.RESULTS:All the 36 patients with multilevel cervical myelopathy were involved in the analysis of results. The mean duration of operation,mean perioperative bleeding amount and mean length of stay in the segmental-decompression group and three-level decompression group were obviously fewer or shorter than those in the long-segmental decompression group(P ＜ 0.05),and the average cost of hospitalization was obviously higher than that in the long-segmental decompression group(P ＜ 0.05). The postoperative improved JOA score and graft fusion rate were close among the groups(P ＞ 0.05).CONCLUSION:Segmental anterior cervical decompression is a recommendable technique for multilevel cervical myelopathy by comprehensively considering the fusion rate,recovery of neurological function,duration of operation,perioperative bleeding and length of stay.

Objective　To evaluate the clinical value of detection of urinary interleukin-8（IL-8） in patients with lupus nephritis （LN）.Methods　Urinary levels of IL-8 were determined by using sandwich ELISA in 38 LN patients.Results　In the LN patients during the　stage　of　normal renal function and diminished renal reserve stage， urinary levels of IL-8 were significantly higher than those in healthy controls（P＜0.001），and urinary levels of IL-8 in the patients during diminished renal reserve stage were significantly higher than those in the patients during normal renal function stage（P＜0.01）.High IL-8 levels in LN patients were associated with high levels of erythrocyte sedimentation rate and lower levels of C3 complement components. Urinary levels of IL-8 in LN patients with microscopic leukocyturia were significantly higher than those without microscopic leukocyturia. In LN patients treated with cyclophosphamide （CTX） and prednisone， urinary IL-8 levels of post-treatment were significantly lower than those of pre-treatment（P＜0.01）. Conclusions 　Urinary levels of IL-8 may be a useful indicator for monitoring disease activity and degree of renal damage in LN. The mechanism of noninfective leukocyturia may be associated with the elevation of urinary IL-8 levels in LN. CTX and prednisone may have a significant effect on inhibiting the production of IL-8 in the immunocytes and renal intrinsic cells.

OBJECTIVE: To compare the clinical effect between Gamma nail and proximal femoral nail (PFN) on the treatment for femoral intertrochanteric fractures in the elderly.METHODS: A total of 131 cases (39 males and 92 females; aged 70?81 years, mean age of 76 years) with femoral intertrochanteric fractures were collected from the Department of Orthopaedics, the Affiliated Changhai Hospital of the Second Military Medical University of Chinese PLA from January 2005 to January 2008. Femoral intertrochanteric fractures were classified based on AO system, including type A1 (n=56) and type A2 (n=75). All cases were randomly divided into Gamma nail group (n=65) and PFN group (n=66). Pre- and post-operative blood loss, blood transfusion volume, operating time, and length of stay were recorded, while the complications were detected following nail implantation. Functional changes of injured limbs were detected after 9 months.RESULTS: At 9 months after following up, there was no significant difference in blood loss, blood transfusion volume, operating time, and length of stay between the two groups before and after implantation (P> 0.05). Furthermore, complications did not occur during or after implantation. Six cases in the PFN group had infection in which of them had diabetes mellitus. There were no complications such as cutting out of femoral head, femoral shaft fractures, breakage of internal device or pushing out phenomenon. All cases got bone union at the final follow-up of nine months and did not get nonunion, delayed union of fractures or shortening of injured extremity.CONCLUSION: Gamma nail and PFN have equal effect on the treatment of femoral intertrochanteric fractures in the elderly.
